Tube well and light well point combined dewatering construction method
The embodiment of the invention relates to a tube well and light well point combined dewatering construction method. The method comprises the following steps: arranging a tube well position according to actual hydrogeological data; arranging a tube well according to the well position of the tube well, and dewatering the tube well; after tube well dewatering is completed, a foundation pit is excavated, and a foundation pit first-stage platform is excavated; light well point well positions are arranged, and light well point pipes are arranged; light well point dewatering is conducted; and after light well point dewatering is completed, a foundation pit secondary platform is dug out. According to the embodiment of the invention, in the deep and large foundation pit with the aquitard, a tube well and light well point combined dewatering mode is adopted, the advantages of the two dewatering modes are integrated, the tube well is used for lowering the overall underground water level of the foundation pit, and then the light well point is used for rapidly draining underground water of the aquifer above the inner negative pressure control depth; the problem of retention and water seepage of the upper portion of the aquitard is solved, and therefore normal construction of a foundation and stability of a foundation pit slope are guaranteed.
本公开实施例是关于一种管井与轻型井点组合降水施工方法。该方法包括：根据实际水文地质数据，布置管井井位；根据所述管井井位布设管井，并进行管井降水；完成所述管井降水后，开挖基坑，并挖出基坑一级平台；布置轻型井点井位并布设轻型井点管；进行轻型井点降水；完成所述轻型井点降水后，挖出基坑二级平台。本公开实施例在存在弱透水层的深大基坑中，采用管井与轻型井点相结合的降水方式，综合两种降水方式的优点，利用管井降低基坑整体地下水位，再利用轻型井点迅速疏干内负压控制深度以上含水层的地下水，解决弱透水层上部滞留渗水问题，从而保证了地基基础正常施工、基坑边坡的稳定。
