Subway foundation pit support structure and construction method thereof
The invention discloses a subway foundation pit support structure and a construction method thereof, and belongs to the technical field of building construction. The enclosure structure comprises a supporting assembly arranged on the side wall of the foundation pit, the supporting assembly comprises a plurality of supporting plates and connecting assemblies for connecting the vertically adjacent supporting plates, the supporting plates are spliced up and down and left and right, and the upper end of the lower supporting plate is in lap joint with the lower end of the upper supporting plate; the connecting assembly comprises a supporting block and a bolt arranged on the supporting block, the supporting block is installed at the lower end of the supporting plate, the bolt penetrates through the upper end of the supporting plate below, and the protruding end of the bolt is in threaded connection with a nut attached to the surface of the supporting plate. The construction method comprises the four steps of a, construction preparation, b, earthwork excavation, c, supporting structure connection and d, drainage preparation. The supporting assemblies on the upper layer and the lower layer can be connected together, and the safety performance of the enclosure structure is further improved.
本发明公开了一种地铁基坑围护结构及其施工方法，属于建筑施工技术领域；围护结构包括设于基坑侧壁上的支撑组件，支撑组件包括多个支护板以及连接上下相邻支护板的连接组件，支护板上下左右拼接，且下方的支护板上端搭接在上方的支护板下端；连接组件包括支撑块以及设于支撑块上的螺栓，支撑块安装在支护板的下端，螺栓穿过下方的支护板上端，且螺栓突出的端部螺纹连接有贴合在支护板表面上的螺母；施工方法包括a.施工准备：b.土方挖掘：c.支撑结构连接：d.排水准备四个步骤。使上下层的支撑组件能够相互连接在一起，进一步提高围护结构的安全性能。
