Method for reinforcing slope protection piles during deepening of foundation pit
The method comprises the following steps that before the foundation pit is deepened, a revetment at the edge of the upper end of the foundation pit is excavated to expand outwards, and after the revetment is expanded, a reinforcing pile is put into the portion, located on the side, away from the foundation pit, of each revetment pile outside a waterproof curtain; an annular reinforcing top beam is arranged at the upper ends of the reinforcing piles, and the upper end of each reinforcing pile is fixedly connected with the reinforcing top beam; a plurality of connecting beams are annularly arranged between the reinforcing top beam and the original top beam at intervals, the connecting beams correspond to the reinforcing piles one to one, one end of each connecting beam is connected with the upper end of the corresponding reinforcing pile, and the other end of each connecting beam is fixedly connected with the upper end of the slope protection pile close to the corresponding reinforcing pile; the bottom wall of the foundation pit is excavated and deepened, after the foundation pit is deepened, a bottom ring beam and a waist ring beam are arranged in the foundation pit along the edge of the bottom wall and the edge of the waist portion of the foundation pit correspondingly, and anchor cables which are downwards inserted into soil beside the foundation pit are arranged on the bottom ring beam and the waist ring beam correspondingly. The construction is convenient, and the cost is controllable.
本发明公开了一种基坑加深时护坡桩的加固方法,步骤如下:在基坑加深前,对基坑上端边缘处的护坡进行开挖以向外扩容，护坡扩容后在止水帷幕外位于每个护坡桩背离基坑的一侧下入加固桩；在多个加固桩的上端设置环形的加固顶梁,且每个加固桩的上端与加固顶梁连接固定；在加固顶梁与原顶梁之间环向间隔设置多根连接梁,且多根连接梁与多根加固桩一一对应,每根连接梁的一端与对应加固桩的上端连接,另一端与靠近对应加固桩的护坡桩的上端连接固定；对基坑的底壁进行开挖加深，在基坑加深完成后，在基坑内沿其底壁的边缘和其腰部的边缘分别设置底环梁和腰环梁，并分别在底环梁和腰环梁上设置下入到基坑旁边土壤中的锚索。其施工方便，且成本可控。
