Wave type wave-absorbing dam

Abstract

The invention relates to a wave type wave-absorbing dam which comprises a stair type dam bottom, a wave type grid wall and a wave-resisting wall, wherein the wave-resisting wall is mounted at the top end of the stair type dam bottom; the wave type grid wall is vertically mounted on the stair surface of the stair type dam bottom; the horizontal cross section of the wave type grid wall is wave-shaped; the wave type grid wall consists of an arced wall at the entrance, an arced wall at the final point and an arced wall in the middle section; the central angle of the arced wall at the entrance is 60 degrees; the central angle of the arced wall in the middle section is 120 degrees; the arced wall at the final point is connected with the wave-resisting wall. Due to the adoption of the stair type dam surface, the functions of roughening the protecting surface and eliminating the energy are achieved, and a part of the wave energy can be eliminated; due to the adoption of a wave type grid wall structure, spindrift and vortexes are formed after water flows into the dam, and then the wave is crushed and collided to achieve the energy elimination function; as the wave type grid wall is combined with the stair type dam surface, the wave entering the grid wall is subjected to dual energy elimination, the wave is prevented from raising high and washing the dam bottom, the coast is prevented from being scoured, and a good coast protection function is achieved.

Description

technical field [0001] The invention relates to a wave-type breakwater embankment. Background technique [0002] Waves are one of the main drivers of coastal erosion. Especially in the case of near-shore breaking waves and sand transporting by tidal currents, most of the eroded sediment will diffuse and migrate to areas far from the shore, causing the coast to continuously wash and recede, thereby endangering the safety of embankments. Therefore, engineering measures must be taken to protect the embankment. [0003] The key to embankment protection works is to dissipate waves and prevent tidal currents from transporting sand. At present, vertical breakwaters, oblique wave breakwaters, floating breakwaters, and concrete special-shaped blocks are often used for embankments. These forms of embankments meet the requirements of wave prevention and energy dissipation and people's requirements for landscapes, but they are close to Water is poor.
