Introduction to the construction steps of installing highway guardrail

The following steps should be followed when using the highway guardrail

     1. Construction preparation

     Before the construction begins, the construction technicians are familiar with and understand the design drawings and related construction specifications, and check with the construction personnel to the construction site and the design drawings to find out the construction number of the construction section, various structures and various structural fences. Location, and at the same time do the construction equipment and materials into the field.

     2, the placement of the wave guardrail

     (1) The column should be staked according to the design drawings, and the bridge, channel, culvert, interchange, and level crossing should be used as the control points for distance measurement. The adjustment section can be used to adjust the spacing, and the distribution method can be used to deal with the number of pitches.

     (2) In order to accurately stake out and ensure the line shape of the guardrail, the piles are checked and closed.

     (3) After the column is staked, the surface state of each column position should be investigated. In case of underground communication lines, water discharge, etc., or when the depth of the top of the culvert is insufficient, the position of some columns should be adjusted to change the way of fixing the column.
