Karst geology foundation pit dewatering and drainage structure and construction method
The invention relates to the field of foundation pit drainage construction, and particularly discloses a karst geology foundation pit dewatering and drainage structure and a construction method.The dewatering and drainage structure comprises a slope top drainage ditch arranged at the slope top and used for intercepting slope top accumulated water, and a slope bottom drainage ditch arranged at the slope toe of the pit bottom and used for collecting slope bottom accumulated water; the blind ditch is arranged at the pit bottom and is used for collecting shallow accumulated water at the pit bottom; a plurality of water collecting wells communicated with the blind ditches are arranged at the slope toe of the pit bottom at intervals, the slope bottom drainage ditches are communicated between every two adjacent water collecting wells, a plurality of dewatering wells used for collecting underground water are evenly distributed in the foundation pit, and a pumping drainage mechanism is further arranged in the foundation pit and used for pumping drainage of accumulated water collected by the water collecting wells and the dewatering wells. According to the construction method, slope top open drainage water interception, slope toe open drainage water collection and blind pipe hidden burying dewatering are combined, the three modes cooperate for dewatering and drainage, the dewatering and drainage efficiency is high, the construction technology is simple, the occupied area of a foundation pit construction area is small, and the construction method is particularly suitable for construction of the foundation pit in the karst area.
本申请涉及基坑排水施工领域，具体公开了一种岩溶地质基坑降排水结构及施工方法，降排水结构包括设置于坡顶用于截流坡顶积水的坡顶排水沟、设置于坑底坡脚处用于收集坡底积水的坡底排水沟，以及设置于坑底用于收集坑底的浅层积水的盲沟；坑底坡脚处间隔设置有多个与盲沟连通的集水井，坡底排水沟连通于相邻的两个集水井之间，基坑内均匀分布有多个用于收集地下水的降水井，基坑中还设置有抽排机构，用于对集水井和降水井收集的积水进行抽排。本申请采用坡顶明排截水、坡脚明排收水、盲管暗埋降水结合，三种方式协同降排水，降排水效率高，施工工艺简单，对基坑施工区域的占用面积小，特别适用于岩溶地区基坑的施工。
