Repair structure and repair method for reservoir bottom geomembrane anti-seepage blanket with water
The invention discloses a reservoir bottom geomembrane anti-seepage blanket with water repairing structure and method, the repairing structure comprises an anti-seepage structure, an outer cofferdam and an inner cofferdam, the outer cofferdam and the inner cofferdam are located above the anti-seepage structure, the inner cofferdam divides a foundation pit defined by the outer cofferdam into a geomembrane repairing area and a shallow water working area, and the geomembrane repairing area is located above the inner cofferdam. The first drainage system, the second drainage system, the total drainage system and the water containing bucket are located in the shallow water working area, a drainage bin is arranged in the geomembrane repairing area and used for absorbing reverse seepage water of the geomembrane repairing area, a water inlet of the first drainage system is connected with the drainage bin, and a water outlet of the first drainage system is connected with the water containing bucket to drain the seepage water of the geomembrane repairing area. A water inlet of the second drainage system is located in the shallow water working area to drain seepage water in the shallow water working area, and a water outlet of the second drainage system is connected with the water containing barrel. Under the condition that the reservoir is not emptied, the reservoir bottom geomembrane underwater repairing work can be completed.
本发明公开了一种库底土工膜防渗铺盖带水修复结构及修复方法，修复结构包括防渗结构、外围堰和内围堰，外围堰和内围堰位于防渗结构上方，内围堰将外围堰围成的基坑分成土工膜修复区和浅水工作区，还包括位于浅水工作区的第一排水系统、第二排水系统、总排水系统和盛水桶，土工膜修复区设有排水仓，用于吸收土工膜修复区的反向渗水，第一排水系统的进水口连接排水仓，出水口连接盛水桶以排出土工膜修复区的渗水，第二排水系统的进水口位于浅水工作区以排出浅水工作区的渗水，出水口连接盛水桶，总排水系统的进水口连接盛水桶，出水口连接外围堰外侧。本发明可以在不放空水库的情况下，完成库底土工膜水下修复工作。
