When we have new inspiration after reflection, we might as well write it down as experience and keep it in mind, so as to formulate a good summary method. Do you know how to write an experience? The following is a model essay (5 general theories) of my civil engineering experience for you. Welcome to reading. I hope you will like it.
Civil engineering experience 1 In a blink of an eye, the one-week cognitive study of civil engineering specialty is coming to an end, and I have gained a lot in this week's study and thinking. Through this professional cognitive study, I have the first opportunity to face the teachers and professors who have been engaged in professional scientific research and teaching for many years in the industry. During the study period, the teacher's vivid explanation, patient answers and professional related documentaries in class gave me a more specific understanding of all directions of civil engineering. Although some professional terms and technical terms are not well understood by teachers, I deeply understand from the teachers' explanations that civil engineering is an exploratory major and a practical one, which is worth practicing all my life.
1, construction engineering
In class, the teacher focused on the advantages and disadvantages of concrete structure and steel structure in engineering practice. Concrete is divided into plain concrete, reinforced concrete and prestressed concrete. Steel structure refers to the building structure with steel as the main body. The advantage of concrete structure lies in its strong corrosion resistance, but the disadvantage lies in its heavy weight. The advantage of steel structure lies in its good elasticity, but the disadvantage lies in its poor fire prevention ability.
Construction engineering refers to all kinds of technical work and completed engineering entities such as planning, survey, design, construction and completion of newly built, rebuilt and expanded houses, buildings and their affiliated structures and facilities. Refers to the construction of various houses and buildings, also known as construction workload.
Including factories, theaters, hotels, shops, schools, hospitals and houses; "Ancillary facilities" refer to water towers, bicycle sheds, pools, etc.
2. Bridge engineering
Bridge engineering refers to the working process of bridge survey, design, construction, maintenance and verification, as well as the science and engineering technology to study this process. It is a branch of civil engineering.
In the process of bridge construction and use, it is not uncommon to see reports that cracks affect the engineering quality and even lead to bridge collapse. Concrete cracking can be said to be "frequently-occurring disease" and "frequently-occurring disease", which often puzzles bridge engineers and technicians. In fact, many cracks can be overcome and controlled if certain design and construction measures are taken. In order to further strengthen the understanding of concrete bridge cracks, try to avoid the occurrence of harmful cracks in engineering, comprehensively analyze and summarize the types and causes of concrete bridge cracks as far as possible, so as to find out feasible methods to control cracks, facilitate design and construction, and achieve the role of nip in the bud. In the process of bridge construction, water conservancy facilities outside the scope occupied by the bridge shall not be damaged, and construction waste and soil shall not be dumped into the river, and the management of the water conservancy department shall be coordinated. The construction scheme of river closure shall not be adopted in bridge construction to ensure the normal flow of river water.
3, underground engineering
Underground engineering refers to underground civil engineering that goes deep into the ground to develop and utilize underground space resources. Including underground houses and structures, underground railways, highway tunnels, underwater tunnels, underpasses crossing the street, etc.
Construction methods of underground engineering: open excavation, shallow burial and underground excavation. There are two forms of open excavation: slope excavation and non-slope excavation.
4. Geotechnical engineering
The teacher told us that in civil engineering, the so-called "soil" refers to geotechnical engineering and "wood" refers to structural engineering. The teacher mainly talked about the object of geotechnical engineering research is rock mass and soil. In the whole geological history of its formation and existence, rock mass has experienced various complex geological processes, so it has complex structure and geostress field environment. However, due to different geological processes, the engineering properties of different types of rock masses in different regions are often very different. After rocks are exposed to the surface, they are weathered to form soil. They either stay in place, or are eroded and transported by wind, water and glaciers and deposited in different places to form soil layers.
The strength characteristics, deformation characteristics and permeability characteristics of rock and soil are all determined by experiments. In the indoor test, the representative of undisturbed samples, the inevitable disturbance during sampling, the release of initial stress, the difference between the test boundary conditions and the actual situation in the foundation and other objective reasons make the indoor test results different from the actual characteristics of rock and soil in the foundation. In in-situ testing, it is also difficult to estimate the errors caused by the representativeness of the field measuring points, the disturbance to the rock and soil when the testing elements are buried, and the reliability of the testing method. The above characteristics of geotechnical materials and their tests determine the particularity of geotechnical engineering. Geotechnical engineering is an applied science. In geotechnical engineering analysis, not only comprehensive theoretical knowledge and indoor and outdoor measurement results are needed, but also the experience of application engineers is needed to get satisfactory results.
5. Railway engineering
Railway engineering is a discipline that studies the basic theories and key technologies of planning, survey, design, construction, operation, maintenance and management of transportation infrastructure such as railways, highways, urban roads and airports. This discipline is the source training base of senior railway engineering professionals and the innovative research base of major key technologies in China, and has close ties and cooperation with academic circles at home and abroad. For a long time, it has delivered a large number of high-level technical talents for railway construction in China, and made great contributions to railway scientific and technological progress in China. The research on track dynamics is the first in China, and it is gradually expanded to "train-track-subgrade system dynamics" with trains on the ground and subgrade or bridge under.
Experience in civil engineering II. The five-week internship ended in a blink of an eye. My internship place is the construction site of the dormitory building of XX Institute of Technology in our school. I listened to the arrangement of the graduation design instructor, Mr. XX, and went to the 29th floor for an internship. This website was built by XX Construction Group Company. The internship in this construction site has benefited me a lot, which has enabled us to master more theoretical knowledge about architecture, and theory and practice are closely linked. This internship gave me a good understanding of practical skills and integrated theoretical knowledge into work practice, so I got a better exercise in practical work. As a graduating college student, it is necessary to learn the theoretical knowledge of professional courses well, and the practical study after that should be more important, necessary and scientific. Because of this, we all take this graduation internship seriously, which gives us a deeper rational understanding of this major from practice and lays a solid foundation for future professional study and work. The owners there are all very nice people. If we have any questions, they will patiently explain them to us. They will give us lessons every day when they go to the construction site and tell us the safety precautions in on-site construction. At first, we all felt very fresh. When I first came here, I treated what I saw and heard as a beginner. Construction has just started there, from looking at the construction drawings to the binding of foundation steel bars and pouring concrete. We have recorded what we saw and heard in the log. I look forward to seeing new things there every day to satisfy my curiosity. The first thing we need to know at the construction site is to be able to read the drawings, but we have hardly touched the real construction drawings at school, so we have encountered many problems when reading these drawings. Fortunately, the masters patiently told us and accumulated a lot of experience and knowledge.
After a period of internship at the construction site, I understand that it's not that what you learn in the textbook can't be used, but that you can use it, that you can be flexible, and that you can't extrapolate. The serious problems of this internship are as follows:
Question 1: The theoretical knowledge is not solid enough, such as the curing time of concrete and mortar test blocks, the degree of vibration when making test blocks, the curing temperature and curing time after concrete pouring, and the causes of concrete cracks cannot be analyzed. These concepts are very vague. I didn't know I didn't learn well until I used them in my internship. At school, I just want to cope with the exam, pass the exam, and memorize the key points the teacher said a few days before the exam. After passing the first-level exam, my mind was blank, and no matter whether I used it later, it disappeared into my memory. I didn't realize that I hadn't remembered these things until I needed them, just as no one would ask you these things when I entered the construction site at this moment. But as a technician, I don't know how to maintain the test block, what are the causes of cracks in concrete, and how to guide the construction. The solution to this problem should be firmly grasped in the future study, applied flexibly without rote memorization, and combined with reality.
Problem 2: I'm not familiar with drawings, so I can't imagine the three-dimensional appearance of plane graphics. In this way, it is impossible to clearly determine the right or wrong of construction.
Question 3: If you don't know the latest construction specifications, you can't quickly determine the right or wrong construction.
Question 4: I don't know much about some construction sequences and the operation of each construction process.
Question 5: Theory
Poor ability to connect with reality. There is too little new knowledge about architecture. Question 6: It is easy to confuse the actual elevation with the design elevation when calculating the construction elevation.
After this internship, I have a deeper understanding of the relevant knowledge of engineering. It should be said that there are many professional knowledge learned in school, which is only theoretical and still a little different from reality. This internship is of great help to my ability to read pictures. When you look at the drawings, you know where to pay attention, where to be careful, and where to study the safety during construction. It also gave me practical knowledge of construction project management and construction drawing budget. Under the leadership of engineers and technicians, I learned their excellent qualities by participating in practical work and labor. Because it is an all-weather on-site internship, it has comprehensively tested my skills in all aspects: study, life, psychology, body, thought and so on. It also meets the requirements of being diligent in practice, combining theoretical knowledge with practice, constantly learning, summarizing, gradually improving and innovating in practice, integrating knowledge, skills and wisdom in practice, improving one's comprehensive quality and skills, and laying a good foundation for the success of one's career. Although the construction site is bitter, it is worthwhile to learn some practical things and practice practical skills to solve problems.
Civil engineering experience 3 1. Practice place and schedule:
The basic arrangement is as follows: On the morning of June 20th, 20XX, visit the site of Tongtu Road-Airport Road overpass;
On the morning of June 2 1, 20XX visited the construction site of Yinbao Building in the southwest of Ningbo Yinzhou Museum.
On the morning of June 22nd, 20XX, I visited the construction site of resettlement houses for residents in Wantou Village. On the morning of June 23rd, 20XX visited the construction site of the gymnasium, badminton hall and commercial street in the East Campus of Ningbo Institute of Technology.
Second, the internship purpose:
Cognitive practice is an integral part of our study. We chose the major of civil engineering and studied for one year, but we don't know much about what civil engineering is, only vaguely know that we will be engaged in building houses and bridges in the future. Cognitive practice provides a platform for us to know more about civil engineering specialty. By organizing a visit, we collected some information and materials related to the internship topic, which laid a solid foundation for the smooth completion of the internship. Through practice, the following objectives should be achieved:
(1) Understand the basic structure of roads and bridges;
(2) Understand the composition, construction equipment and construction site plan of a construction organization;
(3) Understand the basic structure of a house;
(4) Understand some public facilities on the road;
(5) Understand the latest trends and development direction in the field of building structures;
(6) Cultivate professional interests and clarify the purpose of study;
(7) Increase perceptual knowledge for our future study of professional knowledge.
Third, the internship process and content:
The four-day cognitive exercise has finally begun. We arrived at the construction site at nine o'clock. The intern teacher first introduced us to some general situations of the project. Then, under the guidance of the practice teacher, we first visited the pavement and bridge structure under the overpass and learned about the road structure including subgrade, subgrade, pavement and ancillary equipment. This kind of pavement is asphalt concrete pavement, which is a kind of flexible pavement, which makes drivers feel more comfortable on it and is adopted by the vast roads in Ningbo. However, the pavement also has shortcomings, and the service time is shorter than that of cement concrete pavement. We also visited the bridge, which generally includes superstructure, substructure, bearing and accessory parts. Superstructure refers to the part of the bridge above the bearing, and its main function is to bear the deck load and traffic load on it. The substructure usually includes piers, abutments and foundations. Bearing is a force transmission device installed on bridge span structure and pier or abutment bearing in bridge. It can not only transmit a great load, but also ensure that the bridge-span structure produces a certain displacement.
The accessory project is a bridge construction project. In addition to the above basic structures, revetment, diversion structure and navigation device are often built as needed. Auxiliary facilities of the bridge include deck pavement, drainage and waterproof system, railings, expansion joints and lighting.
This morning, we visited the construction site of the bank insurance building. At the material stacking place, we saw all kinds of steel bars and large section steel. Because the building is an office building, it is not practical to use steel bars alone for some special columns, so large steel bars can be used instead of steel bars.
Today is the third day of internship, and we came to the construction site of resettlement house for residents in Wantou Village early. This project is a large-scale project, and what we see is the second phase of the second bid section project. First, the intern teacher also introduced us to the basic situation of the project, and then we visited it under the guidance of the engineer. What we see is a 30-story unfinished building. When we entered the tenth floor by elevator, we saw that the building is a shear wall structure, which is very suitable for high-rise residential buildings. For high-rise buildings, because the lateral load of wind is too large for a single frame structure, shear wall structure is adopted.
Today is the last day of our internship. We visited the badminton court, gymnasium and commercial street site of our school. Badminton hall and gymnasium are both characteristic buildings in our school, and a new architectural model-grid structure has been adopted. This is also a common pattern in some special buildings with the improvement of building technology. The structure is used in long-span buildings, and the components are mostly steel pipes and steel sections. The overall structure is beautiful, which makes people feel that the space is relatively empty and comfortable. Finally, I visited the construction site of the school commercial street, which is a three-story building with frame structure. Frame structure is generally suitable for low-rise buildings, and the lateral load is not very large.
Fourth, internship experience:
The source of practical knowledge is also the only truth to test knowledge. Indeed, through this internship, I have learned more about the major of civil engineering, from which I have learned a lot of knowledge that books can't learn. At the same time, we can link the knowledge learned in class with practice and have a better understanding of the knowledge in the textbook. More importantly, this internship stimulated my interest in this major and increased my perceptual knowledge for studying professional knowledge in the future. It's only the first year of college, and the theoretical knowledge of civil engineering specialty is still very few, and the practical knowledge is even blank. In this internship, we still don't understand a lot of knowledge, but I will take these questions to the professional knowledge class in the future to understand. This internship made me feel a lot and gained a lot. I will continue to understand and appreciate what I have learned in my internship, and I will apply my theoretical knowledge and practical experience to my future work and study.
Constantly apply it to practical work, and fully show your personal value and life value. Strive to realize my ideal and bright future.
Civil engineering experience 4 i. Internship tasks
The requirement of surveying practice is that each team completes large-scale topographic mapping within the specified scope. The whole operation process is also a process from control to fragmentation, from whole to part, involving the operation and use of basic measuring instruments such as level and theodolite. The basic operation methods of leveling, ranging and angle measurement, as well as their recording and calculation methods, the layout and measurement of traverse, the coordinate calculation of traverse, and the mapping operation methods of topographic map. Students must participate in all the above operations and calculations, and master the operation and calculation methods of each link.
The purpose of internship
Through practice, comprehensively consolidate and improve the basic theoretical knowledge of engineering surveying and the basic operational skills of surveying. In practice, the whole process of large-scale topographic mapping in small areas is combined to train students' organizational ability in mapping projects.
Survey of survey area
This time, our investigation area is mainly the library and its surrounding roads, lawns and flower beds. The existing control points are t 10, t1,t 12, t 13, t 14 and t 15. The whole terrain has no ups and downs, the elevation is uniform and the measurement difficulty is moderate.
Second, the content of surveying and mapping
Measurement is a pragmatic and realistic work, and it must not be sloppy. In measurement practice, it is also very important to keep the data original. In order to ensure the correctness and effectiveness of the calculation, we repeatedly check whether the data of each measuring point is correct. Of course, we will inevitably make some mistakes in the measurement, such as inaccurate reading, non-centered bubbles and so on. , will cause some errors. Therefore, we always keep measuring, calculating and drawing at the same time in the measurement, so that mistakes can be found and corrected in time, and at the same time, many unnecessary troubles are avoided, time is saved and work efficiency is improved.
1, fourth-class leveling
According to the given control point t 15 and the six broken steps selected by ourselves, the closed horizontal route around the library is measured. Because we use double readings, the error is very small, and the final height difference is only 0.5mm, and the angle difference is only 48 seconds. Our linear distance is measured by theodolite, so the error is relatively small. The increment of XX coordinate is only +0.52m, and the increment of Y coordinate is only-0.16m.
2, broken step point measurement and topographic map drawing
This part is more complicated. Because of the large terrain, we add six control points according to the known control points, namely 1, 2, 3, 4, 5 and 6 points to form a closed traverse. However, because some angles in the library are difficult to measure, we added a 1 control points to form a branch line. * * * According to the principle of "control first and then break the step", it took 4 days to measure nearly 350 step breaking points and draw a general topographic map with the scale of 1: 500.
Third, the problems and lessons encountered in the internship process
In the past week and a half, we have been sticking to our own "location" library, observing, recording, calculating and tracking points ..... We have worked together to accomplish our task better. However, in the process of measurement, we also encountered many problems and difficulties, such as
(1) When leveling the theodolite, it is difficult to center the leveling tube, and it takes a lot of patience to level it slowly.
(2) When we set the straight line, we estimated the straight line with naked eyes for the first time, and the result error reached 10m. Later, we used theodolite to set out, and the error was much smaller.
(3) The calculation must be done by two people. If only one person is prone to make mistakes in calculation, subsequent calculations will also make mistakes. Therefore, preliminary calculation and inspection are needed.
Fourth, experience
In this internship, we learned the practical ability of measurement and had more endurance in the face of difficulties. At the same time, it also recognizes the importance of group unity and the steps to measure it. First of all, I am familiar with level and optical theodolite, and have mastered the inspection and calibration methods of instruments; Secondly, in the process of data checking and correction, we know the sources of various measurement errors, including instrument error, external influence error, observation error and even recording error. To know how to avoid the error of measurement results, the maximum is to reduce the occurrence of errors, that is, to achieve: 1, improve your own measurement level and reduce errors. 2. Reduce the error through various mathematical methods of data processing, such as taking the average value from many measurements. In addition, we must master a set of scientific measurement methods and follow certain measurement principles, such as "from the whole to the part", "control first and then step by step" and "from high to low", and check step by step. Doing so can not only prevent the accumulation of errors and find them in time, but also improve the efficiency of measurement.
Through engineering practice, the hands-on ability and brain-thinking ability have been greatly improved, and the communication and cooperation ability with classmates has also been expanded. To complete a measurement practice completely, it is far from enough to rely on one person's strength and conception. Only the cooperation and unity of the group can make the exercise complete quickly and efficiently. In this internship, we learned a lot, which made me better master the basic skills and some elements of measurement. At the same time, it also promoted the communication with my classmates, made me understand the importance of unity and mutual assistance and the correct use of the instrument, which laid a solid foundation for me to use the instrument more quickly and accurately in the future.
As a student majoring in civil engineering, we can deeply appreciate the temptation of internship, because it will quickly enhance our professional ability. As the saying goes, practice is the second classroom of university life, the source of continuous innovation and development of knowledge, the touchstone of testing truth and an effective way for college students to exercise and grow. Houses are being built everywhere now, whether for living, office or other functions, we can always see them everywhere, but we can't just enter the construction site, so we used to look from a distance and only saw the external structure. Always want to go in and see what's inside.
As we all know, a person's knowledge and ability can only play a role in practice and be enriched, improved and developed. In order to grow up, college students should be diligent in practice, combine the theoretical knowledge they have learned with practice, keep learning, summarize, improve and innovate in practice, improve their comprehensive quality and ability in practice, and lay a good foundation for the success of their career. Therefore, production practice is an essential practical teaching link in the teaching plan of civil engineering specialty, and it is the unity of theoretical knowledge and engineering practice. So the school can give us this opportunity, and we all cherish it. We hope to improve our professional knowledge and quality through this internship and lay a foundation for future work.
Looking back on the experience of these days, we really learned a lot of real things and thought about many problems. We feel a lot and benefit a lot. This internship at the construction site, we can see the construction process of each team, hear the discussion of the problems by technicians and attend the regular meeting of the project in person, which is our greatest gain. All these have given me a perceptual understanding of the basic situation of project management, and also made a good warm-up for going to work immediately. The short-term study on the spot also improved my professional skills.
The competition in today's society is fierce. As a newcomer who is about to graduate, we should correct our mentality and make a good position for ourselves. We should not be too self-reliant or too self-deprecating. Every job should be earnest and down-to-earth, and only by creating value can we gain something. You should be warm to people and handle the relationships around you. The so-called "being a man before doing things" requires the ability to be a man in particular in the big circle of the construction industry. And we should learn to learn from others with an open mind, ask if you don't understand, and sincerely let others be willing to teach you your own accumulation. This bit by bit accumulation can make you develop continuously.
No matter what kind of work you are engaged in, you need a serious and meticulous work attitude, especially in civil engineering. As the saying goes, a difference of one millionth is a difference of a thousand miles. Because a slight mistake may shorten the life of the project, and even lead to great disasters, this situation is also increasing. When the project is just built, various problems will occur, which will bring great trouble to the residents and even threaten their lives. And it will also bring huge losses to the company. So we should do things seriously and pay attention everywhere.
This short internship opened my eyes, and I deeply realized my own shortcomings. At the same time, I learned a lot of practical things, which also made me think about the industry I want to engage in in in the future. The gap between theory and practice can only be understood by personal experience. The original arrogance disappeared, replaced by down-to-earth determination and confidence to work hard and study. In just over ten days, my thoughts seem to have been sublimated again, and I have gained an insight into life in my heart.
This internship made me deeply realize that reading is a way to increase my knowledge and broaden my horizons, but it is also an excellent choice to improve my comprehensive quality by practicing more, getting in touch with practical work, feeling the pulse of society and setting myself a position. As a contemporary college student, we shoulder the historical responsibility of building the four modernizations. We can't just bury ourselves in reading and talk on paper. It is our ultimate goal to benefit the society with what we have learned. Therefore, we should take part in some such practices to improve ourselves.
Seek to train language communication and communication skills, study hard, do more homework, and actively face every challenge.
Production practice is an essential practical teaching link in the teaching plan of civil engineering specialty, and it is the consistency of theoretical knowledge and engineering practice. During the internship, I went deep into the construction unit as a skilled worker, took a high-rise residential area as an internship place, and participated in the engineering operation industry under the guidance of the director of the skill room of the project department, and successfully completed the two-week internship task. Together, it also laid an excellent foundation for engaging in engineering after graduation from university.
Internship is a strange word to me, because I have experienced many internships in my student life for more than ten years, but this one is so unusual. He will examine all my abilities: study, days, mind, body, thinking and so on. It's like a touchstone to see if I can apply my theoretical knowledge to my internship. It is also the key to whether I can successfully stand in this challenging society after I establish confidence, so so is my investment in it! A month of serious internship is over, and I still have a lot of gains in this half month.
During the inspection of structural column reinforcement, the planning unit chose smooth round steel in the selection of vertical reinforcement, but the friction between stirrup and smooth round steel bound by the construction team was too small in the construction process, which led to the downward sliding of stirrup and brought inconvenience to the construction. So the construction team changed the smooth circular steel bar into threaded steel bar privately to increase the friction and facilitate the binding construction of stirrups, but this change greatly increased the cost. After positive thinking, I put forward the following rectification plan to the director of the skill room: the four vertical bars of the concealed column are two smooth round bars and two threaded bars, which are placed obliquely during construction.
There is no end to learning. After seeing the effect, we should actively think about the factors that cause the problem and how to deal with it. Only in this way can we learn more common sense in our homework and really play a prominent role in integrating theory with practice. In the process of dealing with the engineering skills problems we encounter, we can enhance our ability to analyze and deal with problems.
By studying and practicing many detailed construction methods in the schedule, I have a more real and further understanding of many detailed construction details and treatment processes.
In the process of construction project management, due to various interferences, detailed management development, scheme change, project development scheme and evaluation are often inconsistent with scheme development. This mistake must be corrected by means. We usually choose to track and check the implementation of the development plan, and when we find any doubt, we will take timely measures to deal with it.
After handling the monthly report of construction development, the project manager department can understand the construction development and existing problems of the project. The engineer who works as the scheme will go to the site to check the internship performance of the development scheme, and attend on-site meetings regularly and irregularly to understand the development of engineering practice and coordinate the development of relevant parties together. In the pipe jacking project of Zhang Gui Zhuang Road, Zhonghuan Road undertaken by our company, our project department uses the crossing chart comparison method to compare the actual performance of the project with the difference of scheme and policy.
In practice, you can not only learn common sense, but also learn how to deal with interpersonal relationships. The construction unit is a messy unit, so we should treat people sincerely. When I first came here, I met many new faces, so I didn't dare to talk to them too much because I was unfamiliar, and I didn't know my homework, so I began to get used to it. Later, I gradually found that as long as I am sincere and humble, they are willing to associate with me. In a company, you should not only learn how to do things, but also learn how to be a person. It is very important to correctly handle the relationship between partners, which will affect whether you can carry out your work.
In this internship, I will learn practical knowledge in the big campus of society. This is also the first time that I really contacted and felt the society.
Fortunately, I can touch the master to take me and give me knowledge and assistance in my homework. During the internship, I was able to fully link the theory I learned with the internship and make clear my future development direction. Although I encountered some obstacles such as language at the beginning of my internship, I am more aware of my own shortcomings, work hard, work reliably, and actively face every new opportunity.
