市政污水管道清疏施工技术研究

Research on Municipal Sewage Pipeline Dredging Construction Technology

随着市政污水管道行业发展,市政污水管道清疏给施工造成了很大困扰,主要体现为管道淤塞严重,空气流动较慢,管内淤积状况不能完全掌握,管道周围环境错综复杂,城市污水管密布,现场封堵较难等。介绍道清疏现状,根据现场施工情况,总结清疏的难点及对策,对现场清疏做出简述。

With the development of municipal sewage pipeline industry,the dredging of municipal sewage pipeline has caused great troubles to construction.The main manifestations are serious silting of pipeline,slow air flow,insufficient control of silting condition in pipeline,complex surroundings of pipeline,dense urban sewage pipe,and difficult on-site plugging.This paper introduces the current situation of pipeline evacuation,summarizes the difficulties and Countermeasures of pipeline evacuation according to the construction situation on site,and gives a brief description of pipeline evacuation on site.
