Large deep foundation pit supporting structure and supporting system and construction method thereof
The invention provides a large-scale deep foundation pit supporting structure and system and a construction method thereof.The large-scale deep foundation pit supporting structure and system comprises a main pressure-bearing rod installed in a foundation pit, and the main pressure-bearing rod is provided with a first triangular supporting frame and a second triangular supporting frame; the supporting column is arranged on the lower portion of the main pressure-bearing rod, one end of the supporting column is connected with the main pressure-bearing rod, and the other end of the supporting column is connected with the bottom of a foundation pit. The first triangular supporting frames and the second triangular supporting frames are arranged on the main pressure-bearing rods, the bending strength of the main pressure-bearing rods on the vertical plane is enhanced, the bending strength of the main pressure-bearing rods on the horizontal plane is enhanced through mutual connection of the multiple main pressure-bearing rods, and therefore the requirement of a large foundation pit for the large span is met, and the construction cost is reduced. The number of the supporting columns is greatly reduced, operation at the bottom of a foundation pit is facilitated, the main pressure bearing rod, the first triangular supporting frame and the second triangular supporting frame are composed of a plurality of blocks, transportation is convenient after disassembly, the main pressure bearing rod, the first triangular supporting frame and the second triangular supporting frame are connected through flanges and can be disassembled and reused, and the use cost is reduced.
本申请提出一种大型深基坑支护结构和支护系统及其施工方法，包括：主承压杆，安装与基坑内，所述主承压杆上设有第一三角支撑架和第二三角支撑架；支柱，设于主承压杆下部，所述支柱一端与所述主承压杆连接，所述支柱另一端与基坑底部连接。本申请通过在主承压杆上设置第一三角支撑架和第二三角支撑架，在竖直平面上增强主承压杆的抗弯强度，并且通过多根主承压杆的相互连接，增强主承压杆在水平面上的抗弯强度，从而满足大型基坑对大跨度的需求，极大的减少了支柱的数量，便于在基坑底部进行作业，且主承压杆、第一三角支撑架、第二三角支撑架由多块组成，拆卸后方便运输，且通过法兰连接，可以拆卸重复使用，降低使用成本。
