Construction method of super-long foundation pit supporting servo system adjacent to protected object
The invention relates to a construction method of an ultra-long foundation pit supporting servo system adjacent to a protected object, the system comprises an enclosure structure, a diagonal bracing system, a concrete enclosing purlin and a hydraulic oil cylinder, the diagonal bracing system comprises a first diagonal bracing substructure, a second diagonal bracing substructure and a third diagonal bracing substructure which are separated in the length direction, the first diagonal bracing substructure is arranged at intervals, and the second diagonal bracing substructure is arranged at intervals; the second diagonal bracing substructures are located on the two sides of the first diagonal bracing substructure, and the third diagonal bracing substructure is located between the two second diagonal bracing substructures. A hydraulic oil cylinder is arranged between the concrete enclosing purlins of the first, second and third diagonal bracing substructures and the enclosure structure; and the first, second and third diagonal bracing substructures are sequentially loaded in batches until the support system is formed. A staging wall is omitted, the construction speed is increased, and the cost is reduced; by arranging the first diagonal bracing substructure, the second diagonal bracing substructure and the third diagonal bracing substructure, a large pit is implemented in a partitioned mode, a diagonal bracing system is rapidly formed, and therefore the length of the foundation pit is reduced, the long-side effect of the foundation pit is reduced, large slope excavation can be conducted, and the construction speed is increased.
本发明涉及一种紧邻保护对象的超长基坑支撑伺服系统的施工方法，该系统包括围护结构、对撑体系、混凝土围檩及液压油缸，对撑体系包括沿长度方向分隔而成的第一、第二及第三对撑子结构，第一对撑子结构间隔设置，第二对撑子结构位于第一对撑子结构的两侧，第三对撑子结构位于两个第二对撑子结构之间；第一、第二和第三对撑子结构的混凝土围檩与围护结构之间设有液压油缸；第一、第二、第三对撑子结构分批依次加载，直至支撑体系形成。本发明取消了分期墙，加快了施工速度，减少了成本；通过设置第一、第二、第三对撑子结构将大坑分区实施，快速形成对撑体系，从而减少基坑的长度，降低了基坑长边效应，还可以进行大斜面开挖，加快施工速度。
