深圳市政顶管工程沉井制作与下沉施工技术

Caisson Production and Sinking Construction Technology in Municipal Jacking Project in Shenzhen

近年来,随着我国社会经济的发展及城市化进程的不断推进,各级城市对市政管网工程不断新建及改造,受施工场地、条件限制、环境复杂、管线密集繁多等因素影响,无法明挖施工时部分管网工程采用顶管工艺进行施工,保证工程施工安全及促进工程进展。本文通过实际案例,结合施工背景、现场地质情况、施工安全可靠性等对沉井施工技术进行了探讨,可为今后类似地质情况的沉井施工提供有益的参考。

In recent years,with the development of China's social economy and the progress of urbanization,cities at all levels have continued to build and renovate municipal pipe network projects.Affected by factors such as construction sites,conditions,complex environments,and intensive pipelines,some pipe network projects adopt jacking construction when open excavation cannot be used to ensure the safety of the project construction and promote the progress of the project.In this paper,through the actual case,combined with the construction background,site geological conditions,construction safety and reliability,the construction technology of the caisson is discussed,which can provide a useful reference for the construction of caisson in similar geological conditions in the future.
