排水工程导流与拆除施工的案例分析——以Y污水泵站进水主干管翻建工程为例

Case Study of Drainage Project Diversion and Demolition Construction--A Case Study of the Inlet Sewage Main Pipe Renovation Project at Y Wastewater Pumping Station

市政排水工程新建、翻建污水管道,有关导流与拆除施工问题往往被忽视。以实际工程案例,从设计与施工角度,分析大口径污水管道导流设计与拆除设计的必要性。导流与拆除施工是工程顺利实施的前提条件。施工阶段,导流与拆除的作业应纳入排水工程设计范围,其工程量需要单独计量,实施过程应十分注意安全生产;导流与拆除过程全员全过程参与质量控制;运行阶段关键节点维修维护需要专门导流与拆除的工程设计。

The construction problems of diversion and demolition of sewage pipelines in municipal drainage projects are often ignored.This paper analyzes the necessity of diversion design and removal design of large-diameter sewage pipeline from the perspective of design and construction with a practical project case.Diversion and demolition are prerequisites for the smooth implementation of the project.Diversion and demolition work shall be included in the design scope of drainage works,and the quantities shall be measured separately.During the implementation process,great attention shall be paid to safe production;The whole staff shall participate in the quality control during the diversion and demolition process,and the maintenance of key nodes in the operation phase requires special engineering design for diversion and demolition.The experience can be used for reference by municipal counterparts.
