摘要
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,以期通过工程实践为以后类似工程提供参考。
The key points of construction control of new-built utility tunnel under the complex environment are mainly analyzed.The technical means of closed reinforcement water stop,dewatering and automation monitoring are used in the original utility tunnel project to ensure the deformation control of the surrounding environment,current utility tunnel and pipelines in the utility tunnel in the periods of earthwork excavation,and connecting construction of the old and new utility tunnels.The multiple waterproof measures to ensure the waterproof effect of the structure are taken in the nodes of connection segments.The practices of this project can provide the reference for the similar projects in the future.
