摘　　要：市政排水工程竖井多采用开槽施工的工艺,施工方便,但是存在开挖面较大,对周围环境影响较大的缺点,同时在城市核心商业区,地下管线复杂,部分管线难以探明,造成开槽施工无法进行施工。针对开槽施工工艺的不足,提出一种锁口悬挂式逆作竖井施工工艺。能够在保证无法改迁管线正常使用的情况下不影响工作井的施工。该文结合工程实例介绍锁口悬挂式逆作竖井的设计原理、施工工艺流程以及操作要点。Slotting construction technology is often used in municipal drainage shaft construction,which is convenient for construction.However,there are some disadvantages,such as large excavation surface and great impact on the surrounding environment.At the same time,in the core commercial area of the city,the underground pipelines are complex,and some pipelines are difficult to find out,which makes the slotting construction unable to carry out construction.Aiming at the shortcomings of slotting construction technology,a construction technology of lock-mouth suspension reverse shaft is proposed.It can ensure that the normal use of the pipeline cannot be changed without affecting the construction of the working well.This paper introduces the design principle,construction process and operation points of the lock hanging reverse shaft with engineering examples.
