Dewatering and drainage construction method for foundation pit
The invention discloses a dewatering and drainage construction method for a foundation pit, and relates to the field of building construction technologies, and the dewatering and drainage construction method comprises the following steps that water collecting wells are excavated at all corner parts of the pit bottom of the foundation pit, inner drainage open trenches are excavated along the periphery of the pit bottom of the foundation pit, and the inner drainage open trenches are communicated with all the water collecting wells; a cofferdam is arranged on the building site and surrounds the foundation pit; an outer drainage open trench is arranged on the outer side of the cofferdam; a waterproof film is laid on the ditch wall of the outer drainage open ditch, the length direction of the waterproof film is in the length direction of the drainage open ditch, the two long edge sides of the waterproof film are in lap joint with the outer side of the outer drainage open ditch respectively, and under the condition that the length of the waterproof film is smaller than that of the outer drainage open ditch, the waterproof film covers the outer drainage open ditch. The multiple waterproof films are sequentially spliced and laid in the length direction of the outer drainage open trench; and one or more water collecting wells are provided with a drainage pump for draining water to the outer drainage open trench. When foundation pit dewatering is carried out, water pumped out of the foundation pit can be prevented from seeping back into the foundation pit in a simple mode.
本申请公开了一种基坑的降排水施工方法，涉及建筑施工技术的领域，包括如下步骤，在基坑坑底的各个角落部位开挖集水井，沿基坑的坑底四周开挖内排水明沟，所述内排水明沟与各所述集水井连通；在建筑场地设置围堰，围堰围绕基坑；围堰外侧设外排水明沟；在外排水明沟的沟壁铺设防水膜，所述防水膜的长度方向沿排水明沟的长度方向，所述防水膜的两长边侧分别搭接在外排水明沟的外侧，所述防水膜长度小于外排水明沟长度的情况下，利用多张所述防水膜沿外排水明沟的长度方向依次拼接铺设；在其中一个或多个集水井设置用于向外排水明沟排水的排水泵。本申请进行基坑降水时，能够以较为简单的方式阻碍基坑内向外抽排的水渗流回基坑内。
