Dual drainage structure for deep foundation pit of pump station and construction method
The invention belongs to the technical field of foundation pit construction, and particularly relates to a pump station deep foundation pit double-drainage structure and a construction method.The pump station deep foundation pit double-drainage structure comprises a foundation pit body, the foundation pit body comprises an upper slope surface, a second-stage berm and a lower slope surface, and a plurality of dewatering wells are formed in the surface of the second-stage berm; an upper drainage ditch communicated with the dewatering well is formed in the table top of the second-stage berm, a lower drainage ditch is formed in the outer edge of the pit bottom of the foundation pit body, a plurality of water collecting wells are dug in the ditch bottom of the lower drainage ditch, and a water retaining dike is arranged on the outer edge of the top of the foundation pit body. The mode of combining water collection and exposed drainage and tube well dewatering is adopted, large-scale upwelling underground water can be drained in time, the safety of the interior of the foundation pit is improved, drainage structures can be used in cooperation, and the drainage efficiency is greatly improved.
本发明属于基坑施工技术领域，尤其是涉及一种泵站深基坑双重排水结构及施工方法，包括基坑主体，所述基坑主体包括上坡面、二级戗台和下坡面，所述二级戗台的台面上开设有多个降水井，所述二级戗台的台面开设有与降水井相连通的上排水沟，所述基坑主体的坑底外缘处开设有下排水沟，所述下排水沟的沟底挖设有多个集水井，所述基坑主体的顶部外缘处设置有挡水堤。本发明采用集水明排+管井降水相结合的方式，可以利于及时排出大规模上涌的地下水，提高基坑内部的安全性，使排水结构可以相互配合使用，大大提高排水效率。
