市政工程勘察过程地下管线保护难点与措施

Difficulties and measures of underground pipeline protection in Municipal Engineering Investigation

市政工程勘察的场地多处于复杂的城市环境,场地内分布有各种类型的地下管网系统,这些管网系统具有隐蔽性强、权属单位多、材质类型多等特征,给地下管线的保护工作带来了难题。文章分析、总结了以往市区内勘察过程管线保护的经验教训,提出了市政工程勘察事前、事中和事后管线保护的措施。

Municipal engineering investigation sites are mostly in complex urban environment,and there are various types of underground pipeline network systems distributed in the site.These pipeline network systems have the characteristics of strong concealment,many own-ership units,and many types of materials,which bring difficulties to the protection of underground pipelines.This paper analyzes and sum-marizes the experiences and lessons of pipeline protection in the past urban investigation,and puts forward the measures of pipeline protec-tion in advance,during and after the municipal engineering investigation.
