摘　　要：在市政工程的给排水顶管项目中，需要设置入孔检查井，较深的检查井多采取沉管施工工艺。结合工程实例，从沉管施工设计理论计算和施工工艺两个方面论述了富水条件下深埋检查井的沉管施工方法，还强调了沉管中出现问题及处理措施。工程实践表明，顶管入孔检查井采用沉管施工工艺能成功解决富水地层的施工问题。Deeper manhole wells for inspecting of the municipal drainage project to pipe-jacking, which are taken immersed tube construction technology, need to be installed. By using the acute example engineering project, the immersed tube methods of water-rich layer deep wells were discussed from the design and construction process of immersed tube construction technology. treatment measures were stressed in this paper. And then problems that rise in the course of construction and Finally, practice shows that construction technology of immersed tube wells can be successfully reqsolved the issues of deeper manhole wells in water-rich strata.
