Description

The present invention relates to a wave-dissipating device, and specifically relates to a float-type wave-dissipating device and a wave-dissipating bank.

Breakwaters are common hydraulic structures used in harbor construction, island development, and protection of marine engineering equipment. Ports built on ocean bays, coasts, or islands often use breakwaters to create protected waters, and some breakwaters prevent port pond silt and waves from eroding the shoreline. It also plays a role. However, traditional breakwaters are usually of the bottom type, and the construction cost increases rapidly as the depth of the construction water area increases, and during construction, large and specialized construction equipment is usually required, making construction more complex. At the same time, once damaged, repair is extremely difficult.

According to theoretical analysis and numerous experimental results, most of the wave energy is concentrated in the surface layer of the water body, and 90% and 98% of the wave energy is concentrated in the surface layer with a water layer thickness twice and three times the wave height, respectively. % is concentrated. Therefore, floating breakwaters have been developed that are tailored to the characteristics of wave energy distribution, and their main advantages include lower cost than fixed breakwaters as water depth increases, and ease of application in soft-soil submarine waters. , no special ground treatment is required, it does not affect seawater exchange, the impact on the coast, water, biological exchanges, environmental conditions of sea bays and estuaries is extremely small, and it can be dismantled and reused at will.

After a long period of development, the floating breakwater has now basically matured in the wave dissipation of medium and high frequency waves, and has a good wave dissipation effect. However, long-period waves have long wavelengths and a large vertical span of energy distribution. The former reduces the reflection coefficient of the floating body to waves to almost zero, while the latter makes it difficult to achieve vertical dissipation and dissipation.The combination of the two will effectively solve the current problem of long wave dissipation.
