Description

Floating breakwater

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floating breakwater, and more particularly to a floating breakwater that attenuates the energy of blue while floating in an aqueous phase.

Generally, breakwaters are outer facilities for protecting harbor facilities and ships from the waves of outer sea, and gravity type structures mostly fixed to the seabed are mainly installed.

Gravity breakwaters are firmly supported on the sea floor and submerged in the seabed, which is a substructure that blocks the flow of seawater, and is supported by the top surface of the sandstone mound, the upper part of which protrudes above the surface of the seawater, It is made of caisson, an upper structure that absorbs the incoming wave energy.

Since these gravity breakwaters are integrally constructed from the bottom to the surface of the sea, they provide a stable advantage, but due to excessive blockage of the sea, there is a problem that the water quality in the port is contaminated because the seawater circulation in the harbor is not made smoothly. However, in the area where tidal tides are large, the upper structure must be installed on the basis of the high tide, so the height of the upper structure becomes higher than necessary in the low tide, and excessive amount is required to firmly support the lower structure on the sea floor. In addition to dredging and increase of facility materials, the difficulty of construction is very high due to underwater construction.

On the other hand, in order to solve the problems of the gravity breakwater floating floating body is known to reflect or vanish the blue waves pushed from the sea to the inner sea by fixing the floating body on the sea surface via a chain or cable mediated.

Such float breakwater has a deep water depth, a large difference in tidal range, a weak ground, and can be installed at a low cost in a short period of time where the installation of breakwaters is difficult, and the water pollution of the port can be prevented.

However, the conventional floating breakwater has a structure in which a floating main body is formed by welding steels to have an internal space having buoyancy, and thus is susceptible to corrosion and heavy, requiring high floating force, and causing internal floating by partial breakage. If water enters the space, it can sink easily. In order to suppress the inundation caused by partial breakage, even when the internal floating space of the floating body is partitioned into a plurality of independent floating spaces, condensation water is generated due to the temperature difference with the water temperature in the internal floating space. The problem arises by decreasing the floating force.

The present invention was devised to improve the above problems, while improving the attenuation efficiency of the wave energy while smoothly discharging the water generated by condensation in the inner space providing the floating force while improving the floating force. The purpose is to provide a floating breakwater.
