摘　　要：城市排水设施是城市基础设施的重要组成部分,在市区施工中经常遇到井位和管位施工与现有道路、管道冲突的矛盾。本文以上海昌平、康定地区排水系统改造工程为例,针对设计顶管施工中井位和管位设置与现状道路、施工作业环境的矛盾,提出了解决措施,总结了顶管工作井施工工艺优化方案、井位设置优化技术要点及实施效果,以期为类似工程提供借鉴。Urban drainage facilities is an important part of urban infrastructure. The contradiction of well position and pipe position construction conflict with existing roads and pipelines is always encountered in urban construction. Drainage system reconstruction project in Shanghai Changping and Kangding is adopted as an example in the paper. Solutions are proposed aiming at the contradiction of well position and pipe position setting with existing roads and construction operation environment in the design of jacking construction. The construction technology optimization plan of the jacking working well, keys of well position setting optimization technology and implementation effects are summarized, thereby providing reference for similar projects.
