H-shaped double-row pile foundation pit supporting structure and construction method thereof
The invention belongs to the technical field of foundation pit supporting, and discloses an h-shaped double-row-pile foundation pit supporting structure and a construction method thereof.The h-shaped double-row-pile foundation pit supporting structure comprises a plurality of front-row piles, a plurality of rear-row piles, a front crown beam, a rear crown beam, a first connecting beam, a purline and a plurality of second connecting beams, the pile top elevation of the front-row piles is lower than that of the rear-row piles, the pile tops of the front-row piles are lower than the top face of the foundation pit, the front crown beam is fixed to the tops of the front-row piles arranged in sequence, the rear crown beam is fixed to the tops of the rear-row piles arranged in sequence and is as high as the current ground, and the front crown beam and the rear crown beam are connected through a first connecting beam. And a purline is fixed on the rear-row piles at the same height as the front crown beams, the purline is connected with the front crown beams through second connecting beams, and the second connecting beams correspond to the first connecting beams in position one by one. According to the foundation pit supporting structure, the end bearing performance of the front-row piles is fully utilized, the horizontal bending resistance is high, and the overall stability is high.
本发明属于基坑支护技术领域，公开了一种h型双排桩基坑支护结构及其施工方法，该h型双排桩基坑支护结构包括若干相对间隔设置的前排桩和后排桩、前冠梁、后冠梁、第一连系梁、围檁、若干第二连系梁，其中，前排桩的桩顶标高低于后排桩的桩顶标高，前排桩的桩顶低于基坑顶面，前冠梁固定于依次排列的前排桩顶部，后冠梁固定于依次排列的后排桩顶部且与现状地面等高，前冠梁和后冠梁之间通过第一连系梁连接；后排桩上与前冠梁等高处固定有围檁，围檁与前冠梁通过第二连系梁连接，第二连系梁与第一连系梁的位置一一对应。本申请的基坑支护结构充分利用前排桩端承性能，水平抗弯性能强，整体稳定性高。
