High-flow water seepage and quicksand blocking method for secant piles of foundation pit
The invention discloses a plugging method for large-flow water seepage and quicksand of secant piles of a foundation pit, which is realized by the following steps of: 1, in the foundation pit, firstly, plugging a water leakage point of the foundation pit by adopting objects such as cotton quilts and the like (4), and sealing a larger gap between guard piles (1) by using a steel plate or a thick wood plate (3); (2) planting steel bars on the outer side of the steel plate or thick wood plate (3) for anchoring, and pouring concrete on the inner side for blocking; 2, outside the foundation pit: 1) reserving a pressure relief water outlet pipe (2) below the fender pile (1), wherein the pressure relief water outlet pipe (2) is externally connected with an upward pressure relief pipe (5); (2) drill holes are formed in the positions close to the outer sides of the fender posts (1), and three holes, two grouting holes (6) and an air outlet hole (7) are drilled in the ground of the upper portion of each water leakage point at intervals of 30-60 cm. While internal and external plugging is implemented, internal and external water pressure of the foundation pit is balanced, so that further loss of water and sand outside the foundation pit is reduced.
本发明公开了一种基坑咬合桩大流量渗水、流沙的封堵方法，它是通过以下步骤予以实现的：一、基坑内：1）先采用棉被等物(4)对基坑漏水点进行堵漏，在护桩(1)间间隙较大处使用钢板或厚木(3)板封闭；2）然后将钢板或厚木板(3)外侧植筋锚固，内侧浇筑混凝土封堵；二、基坑外：1)接着护桩(1)的下边预留泄压出水管(2)，该泄压出水管(2)外接向上的泄压管(5)；2)在靠近围护桩(1)的外侧位置布置钻孔，在每个漏水点上部地面处钻三个间距30‑60cm的孔，两个注浆孔(6)，一个出气孔(7)。本发明在实施内外封堵的同时，使基坑内外水压达到一个平衡，从而减少基坑外水、沙的进一步流失。
