Porous floating breakwater suitable for long waves

Abstract

The invention relates to prefabricated and combined porous floating breakwater suitable for long waves. The breakwater can be arranged in harbors, coasts, rivers and the like. Multiple energy dissipation mechanisms such as reflection resistance, energy peak dissipation, turbulence energy consumption, porous seepage energy consumption and the like are adopted. The floating breakwater consists of three parts, namely, floating components, mooring systems and connecting devices between adjacent floating components. The problems that existing breakwaters are complex in construction method, long in construction period and high in engineering cost are solved. Another technical scheme of the breakwater is as follows: in order to realize a better wave dissipation effect, water surfaces of the floating components are set as vertical still water surfaces, a plurality of wave-dissipation through holes are formed in wave surfaces and back surfaces, and grooves are formed in upper surfaces of the floating components, so that the wave energy can be consumed effectively, and the wave height behind the breakwater can be reduced. The breakwater adopts a thin-wall reinforced concrete structure and is high in self-strength; fixing seams are connected into a whole, and the firmness is good; the construction operation is convenient, short in period and high in efficiency; vertical construction can be performed in water surfaces of embankments of canals, ponds, rivers, lakes, seas and the like as well as waters, the foundation earth volume is small, the paving area is small, and the engineering cost is low.

Description

technical field [0001] The invention relates to the field of harbor and coastal hydraulic structures. Background technique [0002] Breakwaters are important hydraulic structures in ports and coasts. It is used to prevent the erosion of waves on the port area and the near coast, to ensure stable waters in the port and near the coast, and may also have the functions of sand prevention, flow prevention, ice prevention, diversion, or the inner side doubles as a pier. With the development of the world economy and the growth of trade, in order to reduce the cost of water transportation and increase the size of ships, the good harbors have been almost completely developed, and the new ports have to be developed in sea areas with deep water, large waves, complex geology and other harsh environments. However, the existing breakwaters, especially for deep-water long-wave absorption effects are not good, and the cost is high, the investment is large, and the soft foundation sea area ...

AI Technical Summary

Problems solved by technology

However, the existing breakwaters, especially for deep-water long-wave absorption effects are not good, and the cost is high, the investment is large, and the soft foundation sea area is difficult to construct, so it is difficult to meet the needs of economic development and construction.
