The invention relates to a foundation pit dewatering construction method, relates to the technical field of foundation pit drainage, and aims at solving the technical problems that the underground water level easily permeates into a foundation pit, and the stability and the influence on the foundation pit in the construction process are serious. According to the technical scheme, the method comprises the following steps that S1, a well position is arranged according to requirements, and the ground elevation is measured; S2, a mud pit is dug beside the well position, and a backflow ditch is manually dug between a wellhead and the mud pit; S3, a drilling machine is in place to the well point position, a well hole is formed, and a well pipe is placed in an inlet hole; S4, filter materials areimmediately filled-in after the well pipe is lowered; S5, after the well point is filled with the filter materials, sealing and compacting are carried out below the wellhead; S6, after well completion, a water pump is lowered into the well for well washing; S7, drainage pipes are paved along the outer side of the foundation pit, and the drainage pipes are connected to a municipal specified drainage position; S8, the water pump is hoisted into the well through a rope; and S9, a water pump power source is started, and water in the well is pumped out. The method has the advantages that ground water permeation in the foundation pit is relieved, and the dewatering effect of the foundation pit is improved.
本发明涉及一种基坑降水施工方法，涉及基坑排水技术领域,其技术问题为地下水位的容易渗透进基坑，对基坑在施工过程中的稳定性，影响较为严重；通过以下技术方案解决，其包括如下步骤：S1、按要求布设井位，并测量地面标高；S2、在井位边挖设泥浆池，井口与泥浆池之间人工挖回流水沟；S3、钻机就位到井点位置，形成井孔，并把井管放置在进孔内；S4、井管下入后立即填入滤料；S5、井点填入滤料后，井口以下封口压实；S6、成井后将水泵下入井内进行洗井；S7、沿基坑外侧铺设排水管，排水管接入市政指定排水位置；S8、水泵采用绳子吊放至井内；S9、启动水泵电源，把井内的水抽出。本发明具有减轻基坑内地面水渗透的情况，提高基坑的降水效果。
