Background
Hundreds of large and medium-sized reservoirs are built in China. Along with the development and utilization of hydropower resources in recent years, fewer and fewer storehouses with excellent engineering geological conditions and greater engineering construction difficulty are provided, and the dam building and the reservoir building in the region with low reservoir bank underground water level, fault development or karst are common at present. Reservoir surface seepage prevention is often required in reservoir sites with poor geological conditions, for example, a concrete panel seepage prevention type is adopted in some projects. The concrete panel has high rigidity and poor adaptability to deformation, and can only adapt to rocky slopes generally. For geological defects such as local weathering deep grooves, geological structure zones, faults and the like, the existing built engineering generally adopts a method of digging grooves, backfilling concrete and then arranging impermeable panels to smoothly connect the panels. There are problems with this:
1. for the engineering of excavating a steep slope, the backfilling concrete increases the sliding force of the slope, and a prestressed anchor cable, an anchor bar pile and the like are required for anchoring, so that the difficulty in slope treatment is increased.
2. If the range of the reservoir basin is large and the range of geological defects is wide, the backfill concrete can reach thousands of squares or even tens of thousands of squares, and huge investment increase is caused.
3. The backfill concrete has large thickness, needs to be poured in layers and blocks, and is troublesome to construct.
