1. During the construction of the guardrail, the information of various facilities should be accurately grasped, especially the exact location of various pipelines buried in the roadbed. No damage to the underground facilities is allowed during the construction process. In case of insufficient depth of underground communication pipeline, drain pipe or culvert filling, the position of the column should be adjusted or the way of fixing the column should be changed.

2. When the column is driven too deep, the column should not be pulled out for correction. The rest should be pulled out, the foundation should be re-compacted, and then the column position should be adjusted.

3. The flange of the bridge should be installed with flanges, pay attention to the positioning of the flange and the control of the elevation of the top surface of the column.
