Abstract
The invention provides an energy dissipation wave wall structure which comprises a wave wall body, an internal energy dissipation box of the wave wall, a wall body bump and a groove which are used for connecting adjacent wave walls, and a through hole for connecting foundation joint bars. After the surging water body enters the internal energy dissipation tank, the energy dissipation effect of the wave wall is enhanced through mutual collision between the water bodies and the wall structure. Meanwhile, the water retaining system of the water retaining surface of the wave wall is mainly an arc surface, so that the impact force of surge on the wall body of the wave wall is reduced, and the overall structure stability of the wall body is improved. The energy dissipation wave wall has a water retaining effect, and the height of the top of the dam can be reduced when the energy dissipation wave wall is arranged on the dam. The energy dissipation structure eliminates the energy of water flow and avoids the damage of the over-high flow velocity of the water flow to the wall body. The main structure of the wave wall adopts the erosion and abrasion resistant concrete material, and the usable life of the structure is prolonged.
