Attention to issues during bridge guardrail construction

1. During the construction of guardrails, accurate information on various facilities should be obtained, especially the precise location of various pipelines buried in the roadbed. No damage to underground facilities is allowed during the construction process. In case of insufficient filling depth for underground communication pipelines, drainage pipes, etc., 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.
