Precautions for guardrail net construction

Guardrail nets are very important transportation infrastructure, and their safety and practicality have very strict requirements. Usually we have to be very careful when installing guardrail nets, and there are many precautions during construction.
Precautions 1. When installing the guardrail net, the construction unit should accurately grasp various construction drawings, and the accurate position of various pipelines buried in the roadbed. During the construction process, no damage to underground facilities is allowed.
Precautions 2. When installing the guardrail net, if the column is driven too deep, the column must not be pulled out for correction. The foundation must be re-compacted before being driven in, or the position of the column must be adjusted directly. When approaching the depth during construction, attention should be paid to controlling the hammer force. Flanges should be installed for railway guardrails, and attention should be paid to the positioning of the flanges and the control of the top elevation of the columns.
Precautions 3. The guardrail net is a safety facility installation project for railways and an important part of the appearance quality of highways. The inherent quality of the guardrail net lies in the raw materials and processing process, and its appearance quality depends on the construction process. During construction, attention should be paid to the combination of construction preparation and pile drivers, and continuous experience should be summed up and construction management should be strengthened to ensure the installation quality.
