Biyang County Shimen Reservoir is a flood control, irrigation, combined with aquaculture, tourism and other comprehensive utilization of medium-sized reservoirs. There is a poor filling quality of the dam body in the reservoir dam, which is not compacted by rolling. The sand foundation of the riverbed section is composed of medium-coarse sand. The dam foundation is not completely removed during construction, and the dam foundation of the platform section and the sub-dam sections are strongly weathered rocks. Seepage phenomenon and seepage of dam abutment. The dam foundation needs to be treated. After comparison and selection of seepage control schemes, the scheme of high pressure swing grouting is finally selected and good results have been achieved.
