1. Labor cost of highway guardrail replacement 1km.
1. First of all, the cost of installing guardrail on expressway is higher than the usual labor cost. After all, there are some safety problems in the expressway, so changing the guardrail about one meter is about 150 yuan.
2. The industrial guardrail we refer to is mainly used in houses, highways, commercial areas and other occasions, and it also has a certain protective effect on personal safety and equipment. Guardrail is also a kind of material that can be seen everywhere in our lives. The guardrail is also different according to the height and length of each meter, and the price is also different.
Second, the highway guardrail installation matters needing attention
1. First of all, the installation of expressway guardrail must be at the rear pay-off, which has a great influence on the appearance quality of corrugated beam guardrail. It is necessary to master the correct method and key points of pile location lofting, and there are some errors in the design of longitudinal and transverse paving kerbs. If all the setting-out places are based on kerbs, and the guardrail column is not straight in the longitudinal direction, after installing the guardrail wrench, the straight part generally has convex and concave surfaces. This is according to the design drawings for column lofting, all controlled by bridges, passages, interchanges and grade crossing. It is necessary to adjust the addresses of some columns and change some ways to fix them.
2. Secondly, after the columns are installed, they are spliced with each other by bolts, and the connecting bolts are fixed on the columns or beams. The splicing direction of corrugated beam is the main installation point, and it must be consistent with the direction and form of chain link during construction. The corrugated beam should be constantly adjusted during installation, so the connecting bolts and splicing bolts should not be tightened too early, so that some long round holes of the corrugated beam can be used for adjustment during installation. After installation, we will conduct a comprehensive inspection and determine the guardrail.
