Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floating jetty with a wave canceller suitable for various boats, departures and arrivals of ships, boarding and alighting, mooring, etc.

[0002]

2. Description of the Related Art Conventionally, floating piers mainly consist of a concrete or steel box-shaped floating body generally called a pontoon, and a floating pier in which a plurality of floating bodies of the same shape are arranged on the lower surface of a deck. The former floating pier receives waves on all sides of the plane, and the wave force received and the reflectance of the waves are large, and the pier is greatly swayed and its stability is impaired. The impact on the mooring and facilities will be excessive. The latter floating pier is divided into multiple floating bodies and the wave force received structurally is relatively reduced, but it does not have a wave-dissipating function, and the pier itself oscillates and the reflectance of waves decreases. Has its own limits.

[0003]

As described above, the conventional floating jetty is apt to be swung by receiving waves directly, or by receiving reflected waves from the quay and the like, and greatly reflecting the waves, thereby providing a jetty function. Is significantly reduced, and there are issues such as adverse effects on moorings, facilities, and navigation in the surrounding area.

The present invention was developed in order to solve the above problems. The object of the present invention is to dispose a plurality of divided floats around the lower surface of the deck and to divide the surface under the water surface. A wave breaker is installed between the floats to break the wave, and the jetty is stabilized and the surrounding water surface is calmed down to provide a floating jetty with a wave breaker that improves the jetty performance as well as the mooring and navigation of the surrounding area. is there.

[0005]

According to the present invention, a plurality of divided floats are arranged at intervals around the lower surface of a deck, and the lower portions of the adjacent divided floats are connected by a horizontal frame. By installing a wave-eliminating device on the floats and arranging them between the split floats under the water surface, the split floats reduce the generation of wave force and reflected waves received by the jetty due to the waves incident from the surroundings, and It is reduced by the wave-eliminating device to effectively reduce the swing of the pier and calm the surrounding water surface.

The wave-eliminating device includes a plate-shaped member which is mounted on a horizontal frame between the lower portions of the divided floats and is arranged horizontally or at a slight inclination inwardly, and the plate-shaped member is a wave-absorbing member. It has a stabilizer function as well as a function to further improve the wave-dissipating performance and the stability of the pier. Furthermore, it is equipped with a large number of slits or holes arranged in the plate-like material, and the slits or holes allow appropriate up-and-down circulation, and the water circulation resistance cushions the wave-dissipating function and the stabilization function of the pier. , Smoothing and increasing reliability.

[0007]

The plural floats arranged at intervals around the lower surface of the deck reduce the wave force received by the jetty due to the waves incident from the surroundings of the deck and the generation of the reflected wave, and the sub-float below the water surface. The wave-dissipating device arranged between the waves efficiently cancels the waves entering from around the deck, the rocking of the jetty is significantly reduced and stabilized, and the surrounding water surface is significantly calmed down. An excellent pier function is obtained, which has a good effect on mooring and navigation in the surrounding area.

Further, in the above-mentioned wave-eliminating device, the plate-like member mounted on the horizontal frame between the lower portions of the divided floats and arranged at a gentle inclination in the horizontal direction or a slightly higher inner side has a function to prevent waves entering from around the deck. In addition to exhibiting excellent wave-dissipating function, it also has a stabilizer function as a stabilizer, which further reduces and stabilizes the swing of the pier and further calms the surrounding water surface. Further, the large number of slits or holes arranged in the plate-like material allow appropriate water flow, and the flow resistance thereof buffers and smooths the wave-dissipating function and the jetty-stabilizing function, thereby improving their reliability. The sex is further enhanced.
