Water-rich sand layer suspended wall supporting structure
The invention belongs to the related technical field of underground structures, particularly relates to a water-rich sand layer suspended wall supporting structure, and aims to solve the problems that equipment installation or track laying in a tunnel can be carried out only after construction of an existing open-cut foundation pit main body structure is completed, the construction period is seriously influenced, an open-cut foundation pit cannot be supported, and in the foundation pit excavation period, the construction period is shortened. According to the technical scheme, the tunnel segment structure comprises a tunnel segment structure arranged at the deep position of the underground; the underground diaphragm wall is arranged in the open cut foundation pit, and the tunnel segment structure penetrates through the underground diaphragm wall; according to the structure, the structure is formed after the tunnel is excavated, the construction period can be shortened, continuous electromechanical equipment installation and construction in the tunnel can be guaranteed in the foundation pit excavation process by using the suspended underground diaphragm wall, and the fan-shaped steel plates are used for blocking, so that the construction period is shortened, and the construction efficiency is improved. And effective water stop of the suspended wall and the duct piece is ensured.
本发明属于地下结构相关技术领域，尤其是一种富水砂层吊脚墙支护结构，针对现有的明挖基坑主体结构施工完成后，才能进行隧道内部的设备安装或轨道铺设，严重影响施工工期，无法使明挖基坑围护和开挖基坑时段内，隧道内设备安装不间断的问题，现提出如下方案，其包括设置在地底深处的隧道管片结构；还包括设置在明挖基坑内的地下连续墙，且隧道管片结构贯穿地下连续墙；还包括上混凝土支撑组、第一钢支撑组、第二钢支撑组和下混凝土支撑组，本发明中，先隧道后明挖结构，可节约工期，使用吊脚地下连续墙可以保证基坑开挖过程中，隧道内部连续机电设备安装施工，利用扇形钢板封堵，保证吊脚墙和管片有效止水。
