Large foundation pit water seepage prevention system for civil engineering

WU MINHUA / ZHU SHUAILONG / XU YUDIAN

The large foundation pit water seepage prevention system for civil engineering comprises a water storage pond, a collecting pipeline is connected to the water storage pond, a plurality of pit bottom water seepage treatment and collection structures and a plurality of pit wall water seepage treatment and collection structures are connected to the collecting pipeline, and each pit bottom water seepage treatment and collection structure comprises an outer sleeve, an inner sleeve and a submersible pump; the pit wall water seepage treatment and collection structure comprises a sleeve box and a plurality of insertion pipes. Through the arrangement of the pit bottom water seepage treatment and collection structure, the pit wall water seepage treatment and collection structure and the arrangement of the water storage pond, water seepage at the bottom of the foundation pit can flow into the pit bottom water seepage treatment and collection structure and then is pumped into the water storage pond to be stored; seeping water at the side wall of the foundation pit can flow into the pit wall seeping water treatment and collection structure and then flow into the water storage pond, so that the purpose of extracting and treating the seeping water of the foundation pit is achieved, and the water accumulation phenomenon caused by continuous water seepage of the foundation pit is prevented.

本发明公开了一种土木工程用大型基坑防渗水系统，包括储水池，储水池上连接有汇集管道，汇集管道上连接有若干坑底渗水处理采集结构和若干坑壁渗水处理采集结构，坑底渗水处理采集结构包括外套管、内套管以及潜水泵，坑壁渗水处理采集结构包括套箱和若干插接管。本发通过设置的坑底渗水处理采集结构和坑壁渗水处理采集结构并设置有储水池，可使基坑底部的渗水能够流入到坑底渗水处理采集结构后被抽送至储水池中进行储存，基坑侧壁处的渗水能够流入到坑壁渗水处理采集结构后流入到储水池内，达到对基坑渗水进行抽取处理的目的，防止基坑因不断渗水产生积水现象的发生。
