工程勘察施工中避让地下管线的探讨

Discussion on Avoiding Underground Pipelines in Engineering Survey and Construction

城市管线分布情况复杂,会对工程勘察施工产生不利影响。为了解决这一问题,论文总结了城市地下管线常见类型及其分布特征,从管线隐蔽性、管材、权属单位、管线数据库等方面分析了工程勘察中管线避让的难点,提出了详细收集地下管线资料、加强地下管线探测(电磁感应法、磁梯度法)、选用聚丙烯(PP)新型钻头等措施来避让地下管线。

The complex distribution of urban pipelines can have adverse effects on engineering survey and construction.In order to solve this problem,this article summarizes the common types and distribution characteristics of urban underground pipelines,and analyzes the difficulties of pipeline avoidance in engineering exploration from the aspects of pipeline concealment,pipe materials,ownership units,pipeline databases,etc.Subsequently,measures such as collecting detailed information on underground pipelines,strengthening underground pipeline detection(electromagnetic induction method,magnetic gradient method),selecting new polypropylene(PP)drill bits,and strengthening training of survey personnel were proposed to avoid underground pipelines.
