Subway station water-rich sand layer deep foundation pit construction supporting structure and construction method
The invention discloses a subway station water-rich sand layer deep foundation pit construction supporting structure and a construction method. The subway station water-rich sand layer deep foundationpit construction supporting structure comprises a plurality of layers of steel sheet pile walls arranged around a foundation pit, each layer of steel sheet pile wall is formed by continuously interlocking a plurality of wavy steel sheet piles, and the inserting and driving depth of the steel sheet pile wall on the inner layer is larger than that of the steel sheet pile wall on the outer layer; and horizontal supporting assemblies are arranged between the opposite steel sheet pile walls and comprise middle supporting pipes and end supporting pipes, the middle supporting pipes and the end supporting pipes are detachably installed, and pressing supporting pieces are arranged between the end supporting pipes and the steel sheet pile walls. According to the subway station water-rich sand layerdeep foundation pit construction supporting structure, the multiple layers of steel sheet pile walls with the depths gradually increased from outside to inside are inserted and driven to be used in the foundation pit with the large depth, the height of each layer of steel sheet pile walls can be controlled within a reasonable range, so that the pile body rigidity of the steel sheet piles is guaranteed, and quite convenience is achieved.
本发明公开了一种地铁车站富水砂层深基坑施工支护结构及施工方法，包括多层设置在基坑四周的钢板桩墙，每层所述钢板桩墙均由多个波浪状板的钢板桩连续互锁而成，内层所述钢板桩墙的插打深度大于外层所述钢板桩墙的插打深度；相对的所述钢板桩墙之间设置有水平支撑组件，所述水平支撑组件包括可拆卸安装的中部撑管及端部撑管，所述端部撑管与钢板桩墙之间设有压紧支撑件。本发明采用由外至内插打深度逐步加深的多层钢板桩墙，来实现在深度较大的基坑使用，每一层钢板桩墙的高度均可控制在较合理的范围内，从而保证钢板桩的桩体刚度，而且也很不方便。
