电力排管施工对临近合流污水管的影响分析及保护研究

Impact Analysis & Protection Research on Electric Discharge Pipe Construction on Adjacent Confluence Sewage Pipe

针对上海地区新建电力排管与既有合流污水管敷设距离较近的情况,分析电力排管开挖(开槽埋管)和非开挖(定向钻进)2种施工工法对合流污水管的影响。根据管线保护的控制标准与经验,提出保护措施来确保污水管的运营安全,通过模拟计算验证措施的有效性。其研究思路、保护方法以及相关结论具有一定的指导意义,可为类似工程的设计与施工提供有益参考。

In view of the fact that the distance between the newly built power drainage pipe and the existing combined sewage pipe is relatively close in Shanghai area,the influence of two construction methods,excavation (grooved buried pipe) and trenchless (directional drilling),on the combined sewage pipe is analyzed.According to the control standard and experience of pipeline protection,protective measures are put forward to ensure the safety of sewer operation,and the effectiveness of the measures is verified by simulation calculation.Its research ideas,protection methods and relevant conclusions have certain guiding significance,and can provide useful reference for the design and construction of similar projects.
