Pipe shed guide wall structure of ultra-shallow-buried large-span underground excavation subway station and construction method
The invention discloses a pipe shed guide wall structure of an ultra-shallow-buried large-span underground excavation subway station and a construction method, the pipe shed guide wall structure is located on the inner side of an open excavation working well foundation pit, and the pipe shed guide wall structure comprises a pipe shed which is formed by arranging a plurality of steel pipes on working well fender posts in parallel at intervals in a penetrating mode and distributing the steel pipes along the outer contours of a plurality of underground excavation pilot tunnels; and the guide wall is fixed to a working well fender post and extends and is distributed along the outer contours of the underground excavation pilot tunnels, and the outer end of the pipe shed penetrates through the guide wall and then is locked. The construction method is good in overall stability, simple in connection joint, easy to construct and operate, easy to guarantee construction quality, high in construction efficiency, capable of shortening the construction period, small in influence on the main body structure of the open-cut working well and waterproof performance and capable of improving the stability of the foundation pit of the working well.
本发明公开了一种超浅埋大跨度暗挖地铁车站的管棚导向墙结构及施工方法，管棚导向墙结构位于明挖工作井基坑内侧，包括：管棚，由多根钢管相互平行地间隔穿设于工作井围护桩上并沿多个暗挖导洞的外轮廓分布形成；以及，导向墙，固定于工作井围护桩上并沿多个暗挖导洞的外轮廓延伸分布，所述管棚的外端穿过所述导向墙后被锁定。本发明整体稳定性好、连接节点简单、施工易操作、施工质量易保证、施工效率高，缩短了施工工期，对明挖工作井主体结构及防水影响小，同时提高了工作井基坑的稳定性。
