The installation method of highway guardrail

1.Basic treatment: Before construction, it is necessary to carry out basic treatment on the road surface, including construction of ramps, filling, excavation, etc., to ensure that the road foundation is flat and meets the requirements of highway guardrail installation.

2.Installation and fixation of highway guardrail: Firstly, it is necessary to set up positioning stakes at fixed positions on the centerline of the road section, and determine the position of each guardrail pole according to the design scheme. Next, use a pile driver to drive the foundation piles underground, and then fix the nuts of the highway guardrail rod onto the foundation piles. Finally, use fixing bolts to tightly connect the guardrail pole to the foundation pile.

3.Splicing and installation of highway guardrail: After the guardrail poles are fixed, guardrail panels need to be installed. Firstly, assemble the guardrail panels and then fix them onto the guardrail posts. When splicing and fixing, it is necessary to ensure that the connection between the highway guardrail and the guardrail rod is firm to ensure the safety of the guardrail.
