Abstract:

The film bag grouting technology injects chemical materials into the film bags by highpressure grouter. As chemical material meets water, it quickly disperses, emulsifies, expands，solidifies and forms a new compound elastomer which makes the film bag expand and completely fill the larger holes or pipes to stop water leakage. Combined with the treatment process of leakage in Xuecheng Hydropower Plant, the application of the filter bag grouting technology is  introduced as a reference for similar cases.
