　　Attention should be paid to the following issues during the construction of bridge guardrails: 1. Accurately grasp the information of various facilities, especially the accurate positions of various pipelines buried in the roadbed, and do not cause any damage to underground facilities during the construction process. In case of insufficient depth of underground communication pipelines, drainage pipes, or culvert roof fill, the position of the columns should be adjusted or the fixing method of the columns should be changed. 2. When the column is driven too deep, it should not be pulled out for correction. All the rest should be pulled out, and the foundation should be re compacted before being driven in, or the position of the column should be adjusted. 3. Bridge guardrails should be installed with flanges, paying attention to the positioning of the flanges and the control of the top elevation of the columns.
