Semi-submersible wave dissipation device and wave dissipation method

Abstract

The invention provides a semi-submersible wave dissipation device which comprises a plurality of interconnected model units. Each model unit comprises a hollow pipe, wherein the upper end and the lower end of the hollow pipe are filled with cylindrical foam columns, holes are formed in the symmetrical positions on the pipe wall of the lower end of the hollow pipe, and a net bag is installed to the lower end of the hollow pipe through the holes. Each model unit is connected to an anchor pile through a cable and submerged blow the water surface. The semi-submersible wave dissipation device can be fully submerged blow the water surface and has no influence on a landscape; through the net bag design at the lower portion of each hollow pipe, buoyancy can be balanced, and shellfish can be cultivated; through the design, sea water exchange is not affected, a space is provided for cultivation, economic benefits are brought, the harbor basin quality is well maintained, and therefore, corrosion to a coast and damage to a coastline are reduced, beach protection and siltation promotion are achieved, and multiple functions are achieved.

Description

technical field [0001] The invention belongs to the field of sea area control, and in particular relates to a semi-submersible wave dissipation device and a wave dissipation method. Background technique [0002] For a long time, waves have brought many negative effects on human engineering activities and civilization development. Under the erosion of waves, natural bank slopes and embankment structures will be washed, eroded, transported and finally destroyed, endangering the safety of the project. Traditionally, the cost of wave-dissipating devices is high, which is not proportional to the practicality of materials and the consumption of wave energy. For example, the oblique wave-dissipating device, although its structural form and actual construction is not difficult, and its wave-dissipating capacity is relatively considerable, but in In the deep water area, the least material is used on the water surface where the wave energy is most concentrated, and a large amount of ...

Problems solved by technology

However, most of the floating wave-dissipating devices are floating on the water, especially for tourist places such as beaches, which will cause damage to the sea area landscape, and the sensory effect will be greatly reduced
