遊式緩衝装置の改良に関するものである。[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a floating shock absorber that absorbs the impact energy when a floating object such as a ship or driftwood collides with an underwater structure such as a bridge pier. This invention relates to improvements to floating shock absorbers that prevent damage to ships and protect underwater structures.
近年、船舶航行量の多い海域に長大橋等が建設

物が衝突する危険が多くなつてきた。
In recent years, long bridges have been constructed in areas where there is a large amount of ship traffic, and this has increased the risk of ships accidentally colliding with underwater structures such as bridge piers, or of floating objects such as driftwood colliding with them. It's here.

限に抑え得るようにしている。 Therefore, a floating shock absorber is installed around an underwater structure, and when a ship enters the underwater structure, this floating shock absorber absorbs the ship's collision energy and protects the underwater structure. This prevents collisions with underwater structures and ships, minimizing damage to underwater structures and ships.

より構成されている。 As shown in FIGS. 8 and 9, the conventional floating shock absorber F of this type has a bale-shaped (straight cylindrical) buoyancy regardless of the external shape of the underwater structure G, especially its shape in plan view. A plurality of fenders 10 provided with water are simply connected to each other by chainnets 20 and connectors 21 to float around the underwater structure G, and are attached to mooring devices 30 to prevent this from being washed away. Therefore, it is configured by being moored to the underwater structure G.

However, the conventional floating shock absorber F having the structure described above has the following drawbacks. That is, (1) In particular, the fender 10b located at the curved corner Gb of the underwater structure G has a smaller area than the fender 10a located at the flat part Ga. It will come into contact with the outer surface. As a result, the fender 10 located at the curved corner Gb
b is the influence of fluctuating external forces such as waves and currents,
Compared to the fender 10a located in the flat area Ga, the fender 10a receives significantly more damage, and the chainnet 20 and connectors 21 wear out prematurely, causing their constituent members to fall off and lose their connection function, and the fender itself to wear out. In the case of pneumatic fenders, there is a risk of sinking, while dents occur and the cushioning performance is quickly impaired.

The distance B is larger than the distance A between the fenders 10a located in the flat portion Ga. As a result, if the ship collides with the bow at the interval B,
Since it does not have a buffering function, there is a risk that the connector 21 will be cut and the bow will directly collide with the underwater structure G, causing the bow to be unilaterally crushed.

This invention is constructed as described above, and the fender located at the curved corner of the underwater structure has its inner surface shape curved in accordance with the curved shape of the corner of the underwater structure. Therefore, it can come into contact with the outer surface of the underwater structure with an area equivalent to that of the fender located on the flat part. Therefore, fenders located in curved corners are affected by fluctuating external forces such as waves and currents to a much greater extent than fenders located in flat areas, as in the conventional case described above. can be prevented.

As described above, the present invention provides a floating shock absorber in which a plurality of fenders imparted with buoyancy are connected to each other and moored to surround an underwater structure. Since the side surface shape is formed in a shape corresponding to the outer surface shape of the underwater structure, and a balancing means is provided on the outside of the fender located at the curved part of the underwater structure, the following effects are achieved. That is, (1) In particular, fenders located in curved parts such as corners of underwater structures should have their inner surfaces curved to correspond to the curved shape of the underwater structure, as described above. Therefore, it can come into contact with the outer surface of the underwater structure with the same area as the fender located on the flat part. Therefore, fenders located in curved areas, like the conventional ones mentioned above, are able to withstand the effects of fluctuating external forces such as waves and currents on flat areas.
Compared to fenders located in Ga, it is not affected significantly. As a result, it is possible to prevent the chainnets and connectors of the fender located in the curved part from being worn out prematurely, and it is also possible to prevent the fender itself from being worn out or dented, which is different from conventional methods of this type. Durability can be significantly improved compared to floating shock absorbers.
