Foundation pit base face water-free construction structure under sandy gravel and mudstone geological conditions
The invention discloses a foundation pit base face water-free construction structure under sandy gravel and mudstone geological conditions. The structure comprises a foundation pit drainage system, awater collecting well and a water pumping and draining system, wherein 1) the foundation pit drainage system comprises a foundation pit side wall drainage system and a foundation pit bottom drainage system, and the foundation pit side wall drainage system communicates with the foundation pit bottom drainage system; 2) the water collecting well is arranged at the bottom of a foundation pit, and thewater collecting well communicates with the foundation pit bottom drainage system so as to collect water at the bottom of the foundation pit into the water collecting well; and 3) the water pumping and draining system is arranged at the water collecting well and is used for draining the water in the water collecting well. The structure is easy to install and operate, the underground water is effectively prevented from permeating into the foundation pit, the defects of a well point dewatering method are effectively overcome, and the potential safety hazard of water-carrying construction of thefoundation pit is reduced; construction of the foundation pit is not affected while the water is pumped and drained, and water-free construction of the base face of the foundation pit is truly achieved; and when the centralized water pumping and draining device system is sealed, a water pump is recovered from the device, and the investment cost of a project is also saved.
本发明公开了一种砂卵石与泥岩地质条件下基坑基面无水化施工结构，其包括：1)基坑排水系统，其包括基坑侧壁排水系统和基坑底部排水系统，所述基坑侧壁排水系统与所述基坑底部排水系统连通；2)集水井，其设置在基坑的底部，所述集水井与所述基坑底部排水系统连通以将基坑底部的水汇集到所述集水井中；3)抽排水系统，其设置在所述集水井处，用于将所述集水井中的水排出。本发明具有安装操作简单，有效防止了地下水渗入基坑，有效弥补了井点降水法的不足，降低了基坑带水施工的安全隐患；抽排水的同时并不影响基坑进行施工，真正的实现了基坑基面的无水化施工；在集中抽排水装置系统密封之时将水泵从装置中回收，也节省了项目的投入成本。
