Method for erecting half-cover excavation foundation pit supporting structure
The invention discloses a half-cover excavation foundation pit supporting structure erecting method, and relates to the technical field of underground engineering, the erecting method comprises the following steps: excavating a foundation pit between a first continuous wall and a second continuous wall; mounting the steel connecting beam; two steel stand columns are vertically arranged between the first continuous wall and the second continuous wall, and the steel connection beam is connected with the two steel stand columns. An upper hanging mechanism and a fixing mechanism are installed on the second continuous wall; assembling and checking the steel support; the steel support is provided with a first end and a second end in the axial direction. Hoisting the steel support; after the steel support is hoisted in place, the bottom of the steel support is supported on the steel connection beam, the first end abuts against the first continuous wall, the second end abuts against the fixing mechanism on the second continuous wall, and the second end is hung to the upper hanging mechanism through a steel wire rope. According to the erecting method for the half-cover-excavation foundation pit supporting structure, the foundation pit supporting structure can be rapidly erected, the problems that a traditional construction method is tedious in construction and long in consumed time are solved, the unsupported exposure time of a foundation pit is effectively shortened, and the foundation pit construction safety degree is improved.
本申请公开一种半盖挖基坑支护结构架设方法，涉及地下工程技术领域，架设方法包括以下步骤：在第一连续墙和第二连续墙之间开挖基坑；安装钢联系梁；第一连续墙和第二连续墙之间竖直设有两根钢立柱，钢联系梁与两根钢立柱相连；在第二连续墙上安装上挂机构和固定机构；拼装校核钢支撑；钢支撑沿轴向具有第一端和第二端；吊装钢支撑；吊装到位后钢支撑的底部承托于钢联系梁上，第一端抵靠于第一连续墙，第二端抵靠于第二连续墙上的固定机构，第二端通过钢丝绳挂接于上挂机构。本说明书所提供的半盖挖基坑支护结构架设方法，能快速架设基坑支护结构，解决了传统施工方法施工繁琐、耗时长的问题，有效减少基坑无支撑暴露时间，提高基坑施工安全度。
