Method for connecting rigid body and flexible body of dam foundation of reservoir

The invention discloses a method for connecting a rigid body and a flexible body of a dam foundation of a reservoir. A lapping-joint method is adopted. In the process of pouring of a thin concrete cutoff wall, the method is characterized by including the steps of drilling out a first-stage slotted hole and a second-stage slotted hole in the thin concrete cutoff wall completely, burying a concrete pipe in the transition segment between the first-stage slotted hole and the second-stage slotted hole, pouring first-stage concrete into the first-stage slotted hole, breaking the position, close to the second-stage slotted hole, of the concrete pipe to form a cavity, drilling out a perpendicular film-laying segment slotted hole in the position, close to the second-stage slotted hole of the thin concrete cutoff wall, placing a vertical film rolling pipe and then spreading out and laying plastic film, filling slurry into the film-laying segment slotted hole, placing guide pipes with the same number in the two sides of the plastic film respectively, and pouring second-stage concrete below the slurry in the film-laying segment slotted hole. The method for connecting the rigid body and the flexible body of the dam foundation of the reservoir has the advantages of being simple and easy to implement, the joint between the rigid body and the flexible body is good in soundness and tightness, and therefore a tight perpendicular seepage-preventing system can be effectively formed.
