Water stop and support integrated foundation pit retaining structure and construction method
The invention relates to a water stopping and supporting integrated foundation pit supporting structure and a construction method, the water stopping and supporting integrated foundation pit supporting structure is used for being arranged at the junction of a foundation pit and the ground, the foundation pit is concavely arranged under the ground, and the water stopping and supporting integrated foundation pit supporting structure comprises a plurality of straight piles, a plurality of inclined piles and a top beam; the multiple straight piles are annularly distributed at intervals along the edge of the junction of the foundation pit and the ground, the lower ends of the multiple straight piles are vertically inserted into the ground, and the horizontal height of the lower ends of the straight piles is smaller than that of the bottom wall of the foundation pit. The horizontal height of the upper ends of the multiple straight piles is between the horizontal height of the bottom wall of the foundation pit and the horizontal height of the ground, and a waterproof curtain arranged in the vertical direction is connected between any two adjacent straight piles under the ground. The straight piles and the inclined piles are integrated through the top beams, the foundation pit supporting cost is reduced, the straight piles and the inclined piles are locally combined, the stability and the supporting strength of the supporting structure are improved, and construction is convenient and fast.
本发明涉及一种止水支护一体化基坑支挡结构及施工方法，用以设置在基坑和地面的交界处，且所述基坑凹设于所述地面下，包括多个直桩、多个斜桩和顶梁；多个所述直桩沿所述基坑和地面交界处的边缘环向间隔分布，多个所述直桩的下端竖向插入地面下，且所述直桩下端的水平高度低于所述基坑底壁的的水平高度，多个所述直桩上端的水平高度介于所述基坑底壁的水平高度和地面的水平高度之间，且所述地面的地下位于任意相邻两个所述直桩之间连接有竖向方向设置的止水帷幕。本发明通过顶梁将直桩和斜桩一体化，降低了基坑支护成本，局部采用直桩和斜桩组合，提高了支挡结构的稳定性和支撑强度，其施工方便、快捷。
