After the main box girder construction is completed, the bridge deck elevation and offset are re-measured, the guardrail position is staked out, and the guardrail reinforcement is installed. Traditionally, the installation of guardrail reinforcement bars involves staking out points and positioning the bars one by one using a ruler. This results in inaccurate positioning and low efficiency. This ultimately results in an unsightly guardrail construction line and a low pass rate for the steel bar protective layer.
