Water falling method for deep foundation pit high water level quicksand geology
The invention discloses a water falling method for deep foundation pit high water level quicksand geology. The method comprises the following steps that firstly, a water collection pit is excavated atthe center position of a foundation pit, thus water in the foundation pit is gathered into the water collection pit, and the water in the water collection pit is drained through a water pump. According to the method, by arranging the water collection pit, the water in the foundation pit is gathered, the water accumulated in the foundation pit is drained conveniently, drilling of a water falling well can be carried out conveniently in the foundation pit construction process, the situation that when the water falling well is drilled, water containing silt flows into the water falling well, andthe well drilling schedule of the water falling well is influenced can be prevented, by means of cooperation between a connecting opening formed in an upper end opening of a cylinder body of each supporting cylinder and a guide head arranged at the lower end, thus the supporting cylinders are stacked and connected more conveniently and rapidly, the construction efficiency of the water falling wellis improved, by arranging a filtering layer and a protecting net, the silt can be stopped, and the situation that due to the high silt content in the water falling well, normal water draining and pumping are influenced can be avoided.
本发明公开了一种深基坑高水位易流沙地质的降水方法，包括以下步骤：S1：在基坑的中心位置挖掘集水坑使得基坑内的水向集水坑中聚集，并通过水泵将集水坑中的水排出。本发明中通过设置的集水坑实现对基坑内的水的聚集方便将基坑中存蓄的水的抽排，方便基坑施工时降水井的打钻，并且防止打钻降水井时含有泥沙的水流进降水井造成回填影响降水井的钻井进度，通过支撑筒的筒体上端口设置的接口和下端设置的导向头的配合使得支撑筒的堆叠相接更加的方便快捷，提高降水井的施工效率，并且通过设置的过滤层和保护网实现对泥沙的阻拦避免降水井中的泥沙含量较高影响正常的抽排水的进行。
