Large excavation construction structure and method for water supply and drainage pipeline underneath passing railway bridge
The invention provides a heavy excavation construction structure and method for water supply and drainage pipeline underneath penetrating railway bridge, the heavy excavation construction structure comprises I-shaped steel and a foundation pit, buttresses are arranged at the two ends of the foundation pit, the I-shaped steel is arranged on the buttresses, the foundation pit comprises an upper cavity and a lower cavity, an inverted filter layer is laid on the inner wall of the lower cavity, and the inverted filter layer is arranged on the inner wall of the upper cavity. A waterproof layer is laid at the bottom of the reverse filtering layer, supporting walls are arranged on the two sides of the reverse filtering layer, sand cushion layers are laid on the waterproof layer and the supporting walls, sleeves are placed on the sand cushion layers and connected with through pipes, openings in the upper ends of the through pipes are connected with grouting pipes, the I-shaped steel is connected with the upper ends of steel wire ropes, and the steel wire ropes are connected with the steel wire ropes. The lower end of the steel wire rope penetrates through the through pipe to be connected with a pipeline, and the pipeline is sleeved with the through pipe. And the grouting accuracy of the pipeline is controlled, so that the water supply pipeline does not leak water during operation, and foundation pit collapse caused by precipitation operation during construction is prevented.
本发明提供了一种给排水管道下穿铁路桥大开挖施工结构及方法，包括工字钢和基坑，所述基坑的两端设置有支墩，所述工字钢设置在支墩上，所述基坑包括上腔室和下腔室，所述下腔室的内壁上铺设有反过滤层，所述反过滤层的底部上铺设有防水层，两侧设置有支护壁,所述防水层和支护壁上均铺设有砂垫层，所述砂垫层上放置有套管，所述套管上连接有通管，所述通管的上端开口连接有注浆管，所述工字钢上连接有钢丝绳的上端，所述钢丝绳的下端穿过通管连接有管道，所述管道套在通管内。控制管道注浆精确度使运营期间给水管道不漏水，防止施工期间降水作业使基坑垮塌。
