Anti-seepage treatment of wet foundation surface with high groundwater pressure
Project Overview:
Xiangjiaba Hydropower Station is located in the lower reaches of the Jinsha River. The barrage dam is a concrete gravity dam with an elevation of 384 meters, the maximum dam height of 162 meters and a length of 909.26 meters. It is the third largest hydropower station in China and the fifth largest hydropower station in the world.The dam elevator shaft is located at the 140m head, the wall thickness of about 30cm, perennial water seepage area.Because it is the back surface waterproof, so the general waterproof coating can not be solved, so the use of good solid in the back surface spraying treatment.
construction procedure:
Remove the putty layer on the base surface and clean the first Christie (150ml / m2) for the second Christie (100ml / m2) for 28 days
Effect evaluation:
There is a large area of water seepage, and some water even flows along the wall; on the back surface, the problem of water seepage can be effectively solved.
Jiagushi is not affected by the humidity of the base surface very well play the effect of its back water surface protection and leakage repair.
