In the past, PCV version 5.6 was often used, but the editing amount after drawing was too large, and some engineering quantities were not calculated accurately.
Now there is an improved version of PCVX6.5, which has improved its functions and made many amendments to the above problems.
Let me talk about the basic introduction of PCVX6.5 and the difference between PCV5.6 for your reference:
I. Overview of PCVX:
PCVX is a software system for highway culvert design and achievement drawing, which combines culvert design theory with highway computer aided engineering (CAE). For culvert design engineers and experts and scholars in culvert theory research, it is necessary to realize the design and conception of their culverts quickly and get the results quickly through CAD. Based on the theory of culvert design in highway engineering, we can get the most basic and important knowledge and examples from the development environment of PCVX!
1. In PCVX, the number of culvert holes supports the culvert layout of any hole; The layout of culverts supports oblique forward construction and oblique construction, except open culvert and box culvert. The types of supporting culverts are: (1), slab culvert, (2), slab culvert, (3), arch culvert, (4), round pipe culvert (round pipe culvert), (5), round pipe culvert (inverted siphon), (6), round pipe culvert (corrugated pipe), (7) and box.
2. The opening types and additional openings that 2.PCVX can build for you. (1) The types of openings supported by PCVX: splayed wall, tapered slope, intake chute, side ditch for slope protection, side ditch falling into the well, paving, drainage ditch, stepped chute, inverted siphon shaft, falling into the well, falling into water, pipeline, outlet chute, step, bucket, and multi-level water-falling chute. (Additional opening types supported by PCVX: bucket, multistage stilling basin, inlet chute, ladder and drainage ditch. Paving can be used as additional opening.
3. In PCVX, the types supported at the joints of tunnel body are: I-wall, wing wall, retaining wall and side wall. The combination of caves and bodies supports vertical and parallel construction.
4. In PCVX, there are many supported routing CAD formats, including the following aspects: (1), Hyde, Haiti routing format, (2), Hyde routing format, (3), main routing format, (4) and latitude routing format.
5. Mechanical calculation and hydrological calculation of culvert are supported in 5.PCVX. Specifically, it includes four types of mechanical checking and hydraulic calculation: slab culvert, arch culvert, pipe culvert and box culvert.
6. In PCVX, two kinds of drawing frames are provided for users to choose: customization of PCVX engineering standard drawing frames; Customization of user-defined drawing frame. PCVX standard drawing frame is defined as the standard drawing frame of highway engineering.
7. Powerful processing function of stepped culvert: providing segmented and staggered functions for stepped culvert; Culvert top can be placed horizontally and obliquely (compatible with old PCV5.6 version); For the ladder culvert, the system will automatically learn the settings according to your control parameters.
8. The control methods of culverts include: the entrance elevation, exit elevation and center elevation of culverts, and only the longitudinal slopes at the entrance and exit of culverts are controlled in combination; It also provides a method to control culverts through slope width.
9. Diversification of drawing frame: two forms, custom drawing frame and system setting drawing frame, are supported.
Second, the version difference between PCVX and PCV5.6
In the process of system design and analysis, PCVX inherited all the essence of PCV5.6, combined with all customer problems since PCVX 1.0 was released, and developed an excellent culvert CAE software system according to the needs of culvert design. The main differences between PCVX and PCV version 5.6 are as follows:
1, the system runs faster: PCVX adopts ObjectARX development package and codes with VC++, which can share memory address space with AutoCAD, which is natural with AutoCAD environment.
2. Support the new standard: support the structural calculation of load grade (including automobile 1 and 2, urban road load, etc.). ) stipulated in the new bridge and culvert specification; Support the specification of new standard drawings and the drawing of structural drawings; Support the drawing of layout drawings that meet the new specifications.
3. Culvert types supported by 3.PCVX: open culvert with cover plate, concealed culvert with cover plate, arch culvert, circular culvert (including corrugated culvert, circular culvert and inverted siphon culvert) and box culvert. The number of culvert holes supports the culvert layout of any hole; Except for Ming Kai culverts and box culverts, which can only be constructed obliquely due to their own characteristics, other types of culverts all support oblique forward construction and oblique construction. Bellows culvert is a new culvert type added by PCVX. In the process of culvert design, slab culvert, arch culvert and circular culvert support any number of culvert holes, oblique construction, oblique construction, positive layout and oblique layout. The function of box culvert takes into account the support of culvert standard drawings and specifications, so the original design and parameter control are followed.
4. Portal forms supported by 4.PCVX: 65,438+07 portal forms, such as splayed walls, tapered slopes, inlet rapids, side ditches for slope protection, side ditch water drop wells, paving, drainage ditches, stepped rapids, inverted siphon shafts, water drops, pipelines, outlet rapids, steps, buckets, multi-stage stilling basins and twisted slope portal. Among them, bucket, multi-stage stilling basin, inlet chute, ladder, drainage ditch and paving can be used as additional openings. The design function of PCVX is much stronger than that of PCVX.
5. Real-time update of culvert design: PCVX can draw design drawings and detailed structural drawings in the process of culvert design through database entities, and can respond to any design parameters or environmental parameters in real time according to user requirements, so that what you see is what you get.
6.PCVX has greatly strengthened the design function of settlement joints: it supports the automatic arrangement, merging and splitting of culvert settlement joints. After the user designs the culvert, PCVX provides the dynamic interactive drag function of the culvert settlement joint and the culvert top section.
7. The design of stepped culvert provided by 7.PCVX is more automatic and free: there are two ways to provide system settings and user-defined settings.
The system will set up stepped culverts: the system will automatically and intelligently set up culverts in sections. When designing a culvert in this mode, if the longitudinal slope of the connecting line between the entrance and exit of the culvert is smaller than the control longitudinal slope of the culvert, the method of setting culvert steps is consistent with the method of designing stepped culverts by users. If the longitudinal slope of the connecting line at the entrance and exit of the culvert is greater than the control longitudinal slope of the culvert, the system will automatically switch to automatically setting stepped culverts in sections. In the process of automatic cutting, PCVX provides two functions: staggered cutting and step-by-step staggered cutting.
During the segmentation process, the system will automatically adjust the mutated segmentation information.
User-set ladder culvert: it is mainly used to set some special subsection information according to actual needs. In the process of calculating PCVX, the system keeps the length of the line segment and the length unchanged.
8. Support grade dislocation and segment dislocation of slab culvert and arch culvert: When designing slab culvert and arch culvert, the system will grade dislocation or segment dislocation of steep slope culvert according to user's settings. In the process of staggered abutment, the top of culvert can be set flat or inclined. When it is flat, the system automatically sets the slope at the top of the culvert as the minimum longitudinal slope at the top of the culvert. When the culvert top is inclined, the user can directly input the slope of the culvert top.
9. Support more combined control methods of culvert elevation layout: In PCVX system, the combined control of entrance elevation, exit elevation, center elevation and longitudinal slope of import and export connection is supported, including: entrance elevation control, entrance elevation and center ratio control, entrance elevation and longitudinal slope control of import and export connection, center elevation and exit elevation control, center elevation and longitudinal slope control of import and export connection, and exit elevation and import and export connection control. In the design process, it also supports the layout control of locking the length and elevation of the entrance or exit, which is more handy when designing and transforming culverts or culverts with building conditions.
10. Input of original design parameters related to subgrade: During the input of original design parameters of subgrade (including design line, ground line and geological line), the following methods are provided: direct input; Click and input with the mouse; Text copy; Text import; From the routing engine; Input of visual standard section, etc.
1 1. dynamic drag function: PCVX adopts the function of solid cycle drag, which realizes the dynamic adjustment function of culvert design parameters on design drawings. For example, you can directly drag grips related to the foundation of the section projection of the slab culvert to change the height or position of the foundation. After the dragging is completed, the system will update the corresponding design parameters according to the user's dragging results and the accuracy requirements set by the user, and update other design components such as elevation simultaneously.
12, AutoCAD environment variables control drawing settings more accurately: PCVX supports modifying drawing layers, label types and text types individually or in batches.
