Connecting structure for dam foundation gallery and dam body core wall
The invention discloses a connecting structure for a dam foundation gallery and a dam body core wall. By means of the connecting structure, the contact slope between the dam foundation gallery and the dam body core wall can be reduced. The connecting structure comprises the dam foundation gallery arranged on a covering layer and the dam body core wall arranged on the covering layer and the dam foundation gallery. The connecting structure further comprises a cushion layer and an inverted filter layer which are arranged between the dam body core wall and the covering layer and located at the upstream side and the downstream side of the dam foundation gallery respectively and a clay layer arranged between the dam foundation gallery and the dam body core wall. A water and leak proofing agent layer, a pitch anti-leakage layer and a composite geo-membrane are arranged on the surface of the dam foundation gallery. The sedimentation amount of the core wall can be reduced through the cushion layer. Piping and flowing soil can be prevented through the inverted filter layer. The deformation between the core wall and the gallery can be coordinated through the clay layer, and the contact slope between the core wall and the gallery can be reduced through the synergistic effect of the clay layer, the cushion layer and the inverted filter layer. By means of the water and leak proofing agent layer, the pitch anti-leakage layer and the composite geo-membrane, the contact slope at the bottom of the core wall and between the core wall and the gallery can be reduced, and the anti-leakage effect of the connecting structure can be reinforced.
