Grid type concrete face rockfill dam

Abstract

The invention relates to the technical field of rockfill dams, in particular to a grid type concrete face rockfill dam. The grid type concrete face rockfill dam comprises a rockfill area, a plurality of layers of first grids, a transition area, a cushion layer area, a concrete face, a second grid and an asphalt concrete face, wherein the plurality of layers of first grids are horizontally laid in the rockfill area, the transition area is arranged on the side surface of the rockfill area, the cushion layer area is arranged on the surface of the transition area, the concrete face is arranged on the cushion layer area, the second grid is arranged on the concrete face, the asphalt concrete face is arranged on the concrete face and is fixedly connected with the second grid, a toe board is arranged on one side of the bottom of the rockfill area, and a bearing sealing gasket which is used for supporting the bottom of the concrete face and the asphalt concrete face is arranged on the toe board. According to the grid type concrete face rockfill dam, the tensile and deformation resistance of the concrete face rockfill dam can be increased, so that the structural damage to the concrete face rockfill dam is not easy to occur.

Description

technical field [0001] The present application relates to the technical field of rockfill dams, in particular to a grid-type concrete face rockfill dam. Background technique [0002] At present, the concrete face rockfill dam is mainly composed of a face plate and a rockfill dam body. The face plate is a thin plate anti-seepage structure located on the upstream surface, and the rockfill dam body plays the role of anti-seepage reinforcement and support. Under the action of self-weight and earthquake load, due to the weak tensile and deformation resistance of concrete materials, there will be large lateral or longitudinal displacements on the concrete face and rockfill dam body, and then the concrete face and rockfill dam body will be deformed. Cracks are easy to occur, which will damage the entire concrete face rockfill dam structure and lead to the failure of the anti-seepage system at this part. [0003] In view of the above-mentioned related technologies, the inventors fo...

Problems solved by technology

Under the action of self-weight and earthquake load, due to the weak tensile and deformation resistance of concrete materials, there will be large lateral or longitudinal displacements on the concrete face and rockfill dam body, and then the concrete face and rockfill dam body will be deformed. Cracks are prone to occur, which will damage the entire concrete face rockfill dam structure and cause the anti-seepage system to fail

[0003] In view of the above-mentioned related technologies, the inventors found that concrete face rockfill dams have weak tensile and deformation resistance, which is prone to structural damage of concrete face rockfill dams and thus affects the anti-seepage performance.
