Foundation pit pile wall integrated structure under complex conditions
The invention relates to the technical field of foundation pit supporting, and discloses a foundation pit pile-wall integrated structure under complex conditions, which comprises an underground diaphragm wall and a plurality of cast-in-place piles, the plurality of cast-in-place piles are arranged at the bottom of the underground diaphragm wall, and the plurality of cast-in-place piles and the underground diaphragm wall are connected into a whole to form the pile-wall integrated structure; the underground continuous wall is arranged in the underground continuous wall groove, the cast-in-place pile is arranged in the cast-in-place pile hole, the cast-in-place pile hole extends downwards from the bottom of the underground continuous wall groove into the underground slightly-weathered rock stratum, and the cast-in-place pile hole is communicated with the underground continuous wall groove. The construction technology that under-wall cast-in-place piles replace the underground diaphragm wall embedded into the slightly weathered rock stratum in the depth is adopted, and the hard rock stratum grooving construction difficulty and workload are greatly reduced. Disturbance to an upper soft soil layer is reduced, and the occurrence probability of hole collapse and peripheral settlement is reduced. The requirements on grooving equipment and process can be reduced, the equipment loss is reduced, the grooving efficiency is improved, the construction cost is reduced, and the project progress can be smoothly promoted.
本发明涉及基坑支护的技术领域，公开了复杂条件下基坑桩墙一体化结构，包括地下连续墙和灌注桩，多根灌注桩设于地下连续墙的底部，多根灌注桩与地下连续墙连接成整体，形成桩墙一体化结构；地下连续墙设于地连墙槽中，灌注桩设于灌注桩孔内，灌注桩孔从地连墙槽的底部向下延伸至地下微风化岩层中，灌注桩孔与地连墙槽相连通。采用墙下灌注桩替代嵌入微风化岩层这部分深度地连墙的施工技术，大大减小了硬岩地层成槽施工难度和工作量。减少了对上部软弱土层产生的扰动，降低了塌孔和引起周边沉降的发生概率。对成槽设备、工艺要求会降低，减少了设备损耗，提高了成槽效率，降低了施工成本，有利于项目进程的顺利推进。
