Water-rich stratum foundation pit sheet-pile wall inter-pile gravel inverted filtration anti-seepage structure and construction method
The invention belongs to the field of foundation pit supporting, and particularly relates to a water-rich stratum foundation pit sheet-pile wall inter-pile gravel inverted filtration anti-seepage structure and a construction method. The water-rich stratum foundation pit sheet-pile wall inler-pile gravel inverted filtration anti-seepage structure comprises front-row cast-in-place piles and rear-row cast-in-place piles which are arranged in two rear rows, a pile front soil retaining plate is arranged on the front sides of the front-row cast-in-place piles, the space between the rear side of the pile front soil retaining plate and the front-row cast-in-place piles is filled with a sand gravel inverted filter layer, clay I is arranged at the bottom of the sand gravel inverted filter layer I, and a plurality of drainage holes I are formed in the pile front soil retaining plate and communicate with the sand gravel inverted filter layer I and the outside; a top beam is arranged between the tops of the front-row cast-in-place piles and the rear-row cast-in-place piles, a concrete cushion layer is arranged at the bottom of the top beam, a retaining wall is arranged on the front side of the top of the top beam, a sand gravel inverted filter layer II is arranged on the rear side of the retaining wall, clay II is arranged at the upper end and the lower end of the sand gravel inverted filter layer II, a plurality of drainage holes II are formed in the retaining wall and communicate with the sand gravel inverted filter layer II and the outside, and the retaining wall and the top beam are connected into a whole through supporting ribs.
本发明属于基坑支护领域，具体是一种富水地层基坑桩板墙桩间砂石反滤防渗漏结构及施工方法。包括后两排设置的前排灌注桩和后排灌注桩，前排灌注桩前侧为桩前挡土板，桩前挡土板后侧与前排灌注桩之间填充有砂砾石反滤层，砂砾石反滤层I底部设置有粘土I，桩前挡土板设有若干泄水孔I，泄水孔I连通砂砾石反滤层I与外部，所述的前排灌注桩和后排灌注桩顶部之间设置有冠梁，冠梁底部设置有一层砼垫层，冠梁顶部前侧设置有挡土墙，挡土墙后侧设置砂砾石反滤层II，砂砾石反滤层II上下两端为粘土II，挡土墙上设置有若干泄水孔II，泄水孔II连通砂砾石反滤层II和外界，挡土墙通过扶肋与挡土墙和冠梁连接成整体。
