1. The spacing of the column steel lining must be consistent with the design size to ensure that the pre-assembled semi-finished products can be connected to it.
2. The horizontal and vertical steel lining of the guardrail have been installed and connected before leaving the factory, and the reinforced accessories of each bearing point have also been installed in place. During the construction on site, only the guardrail horizontal lining and the vertical column need to be connected and fixed.
3. Welded wire mesh can use mechanical expansion bolts, chemical screw inspection and other methods to fix the column steel substrate board at the center of the lower foundation for straight distribution.
4. Pull two parallel lines at the upper and lower limits of the straight line distance for the installation and adjustment reference to ensure the straightness of the upper and lower ends after the installation of the guardrail is completed.
