Construction method of multi-stage echelon arrangement foundation pit supporting structure system
The invention relates to a construction method of a multi-stage echelon arrangement foundation pit supporting structure system, which is based on the multi-stage echelon arrangement foundation pit supporting structure system and comprises a first-stage supporting structure, a second-stage supporting structure and a third-stage supporting structure, the first-stage supporting structure, the second-stage supporting structure and the third-stage supporting structure are arranged in a multi-stage echelon mode from top to bottom, and the first-stage supporting structure is arranged on the side close to an important building. According to the foundation pit supporting structure system, the enclosure structure and the supporting structure of each stage of foundation pit are independent, and the stress working conditions of the enclosure structures and the supporting structures are simple; the problems of large foundation pit supporting depth, large earthwork and the like caused by unified descending are avoided, and the construction cost is saved; for the foundation pits which are arranged in an echelon mode, a flexible arrangement mode and a flexible structure mode can be adopted for arrangement of the foundation pit enclosure structure and the supporting system of each stage according to the characteristics of the foundation pits and the protection requirements of adjacent buildings.
本发明涉及一种多级梯次布置基坑支护结构体系的施工方法，所述方法基于多级梯次布置基坑支护结构体系，包括第一级支护结构、第二级支护结构和第三级支护结构，所述第一级支护结构、第二级支护结构和第三级支护结构依上至下分别多级梯次设置，所述第一级支护结构设置在紧邻重要建筑侧。本发明提出的基坑支护结构体系每一级基坑的围护结构和支撑结构均是独立的，围护结构和支撑结构受力工况简单；避免了统一降方造成的基坑支护深度大和土方工程大等问题，节省了工程造价；对于梯次布置的基坑，每一级基坑围护结构和支撑体系的布置可根据基坑特点以及邻近建筑物的保护要求，采用灵活的布置形式及结构形式。
