Abstract:Introduced the situation of leakage,construction difficulties,properties and application ranges of the grouting materials of Huilong Pumped Storage Power Station. Listed the construction technology of each material,adopted the corresponding treatment schemes to variety types of cracks for different construction areas,the cause for the construction cracks of high strength mortar have been analyzed and the concrete treatment measures are listed. Emphasized the necessity of completely repairing various cracks on the surface of the base layer before the anti-seepage construction of the large area polyurea waterproof coatings.
