Artificial channel drainage sandbeach sedimentation reducing system

Abstract

The invention discloses an artificial channel drainage sandbeach sedimentation reducing system, and belongs to the technical field of coastal wetland ecological restoration. The artificial channel drainage sandbeach sedimentation reducing system is arranged on the silt beach side of an open sea and comprises a water injection ditch, a drainage passageway, outer walls and a water injection system.The water injection ditch is arranged on the rear land of the silt beach, the water injection system and the water injection ditch cooperate with each other, water is injected into the water injectionditch all the time, the outer walls are arranged on the two sides of the water injection ditch, water in the water injection ditch is drained to sandbeaches on the two sides through the drainage passageway; fine-particle mud in the drainage passageway is started under the action of water flow and moves, the mud is output along with offshore flow in a tide falling period, and sandbeach argillization is avoided. According to the artificial channel drainage sandbeach sedimentation reducing system, the ditch is artificially excavated, and the function of waves and tide is effectively adjusted toreduce natural hazards. Pollution can be effectively degraded through coast wetland restoration, and the primary ecological system and natural balancing mechanism are restored; and by means of ecological restoration, the diversity of the species is improved. A good basis is provided for further construction of leisure tourism inhabiting facilities, and a basis is provided for tourism development.

Description

technical field [0001] The invention belongs to the technical field of coastal wetland ecological restoration, and in particular relates to an artificial ditch drainage beach silt reduction system. Background technique [0002] Sandy coasts and silty coasts are an important part of my country's mainland coasts. In recent years, with the development of coastal tourism and the impact of human activities, natural beaches and artificial beaches have been hardened, muddy, and even degraded to varying degrees. Coastal tourism is a hot spot in world leisure experience tourism. [0003] "National Marine Economy Development Planning Outline" pointed out: "Coastal tourism is China's pillar marine industry and should be developed with priority." At present, my country has formed five major coastal tourism belts, including the Bohai Bay, the Yangtze River Delta, the west coast of the Strait, the Pearl River Delta, and the coast. [0004] But at present, many beaches in my country are g...

Problems solved by technology

[0005] The dredging of the beach is complicated and requires a lot of manpower and material resources. Once the muddy phenomenon of the beach is formed in the area, even after a short period of manual dredging, muddying will still occur after a period of time. Repeated cleaning is required, and it is difficult to maintain the beach for a long time. clean
