Overlapped wall construction water stop structure in complex stratum

According to the technical scheme, the water stop structure for the overlapped wall construction in the complex stratum is characterized in that the water stop structure comprises a sealing water stop plate, the inner wall of the sealing water stop plate is movably connected with a fastening bolt, the outer wall of the sealing water stop plate is fixedly connected with a supporting block, and the inner wall of the supporting block is movably connected with a movable rod; through the sealing water stop plate, a fastening bolt, a supporting block, a movable rod, a positioning block and a reset spring, the sealing water stop plate can be conveniently installed in a gap between the overlapping walls through the fastening bolt, the fastening bolt can be conveniently positioned and clamped after installation, loosening caused by accidental rotation is avoided, and the service life of the sealing water stop plate is prolonged. And through the fixing protruding blocks and the connecting grooves, splicing of the seali
