复杂环境下综合管廊新建及接舱施工实践

摘要:

本文主要分析复杂环境下新建综合管廊施工控制要点以及对原综合管廊改造工程中采用封闭加固止水、降水、自动化监测等技术手段保证土方开挖、新旧管廊接舱施工阶段,周边环境、现行管廊以及廊内管线的变形情况受控。同时对接舱段节点采用多重防水措施来保证结构的防水效果,以期通过本工程的实践为以后类似工程提供参考。

Abstract:

This paper mainly analyzes the key points of construction control of new comprehensive pipe gallery under complex environment, and uses technical means such as sealing water, precipitation and informationization monitoring to ensure the control of deformation of surrounding environment, current pipe gallery and pipeline in the gallery during earthwork excavation, the construction stage of connecting the old and new pipe gallery with the cabin in the original comprehensive pipe gallery renovation project. At the same time, the docking module node adopts multiple waterproof measures to ensure the waterproof effect of the structure, in order to provide reference for similar projects in the future through the practice of this project.
