1. Template processing shall be stopped according to the mechanical manufacturing process, and rounded corners shall be used at the corners of the template to make its line shape smooth. The dimensions shall be strictly manufactured according to the design requirements. Stop the trial assembly of the manufactured template, and promptly rectify any errors or discrepancies in the overall order of the Taiwan War. Only qualified templates can be used. Template requests have a certain strength and rigidity to ensure that they do not deform during construction. The installation of the anti-collision guardrail template should be strictly stopped according to the standard requirements to ensure that there is no mold running, wrong platform, deformation, or leakage during concrete construction, and to ensure the appearance quality of the concrete.

2. The anti-collision guardrail uses a special release agent to ensure that the concrete color is even and the surface is lubricated.

3. Embed 40cm internal support steel bars at a height of 10cm on the spacing beam surface, ensuring the cross-sectional size of the lower part, and tighten them with tension rods. The top surface is supported by 17cm steel bars and tightened with tension rods to ensure the size of the upper section. Pre embed steel bars at certain intervals on the inner side of the guardrail as support points for the top pull formwork, firmly supporting the guardrail formwork and ensuring its stability.

4. The template joints are pasted with plastic tape at the template joints, and the anti-collision guardrail templates are fastened with screws. The joints between the template and the pavement layer are filled with sponge material to ensure that the joints are tight, without leakage or pollution. Strictly control the phenomenon of misalignment when installing templates.

5. The broken joints of the guardrail are set at the top and middle of the pier. For anti-collision guardrails with a span greater than 30m, appropriate broken joints can be added to avoid stress concentration of concrete under driving loads and ensure that the broken joints are vertical and uniform. The joint shall be disconnected with foam data, and the end formwork shall be made of steel plate.
