【考案の詳細な説明】 この考案は係船岸壁、とくに荒天時にも船舶を係留する
ことができる係船岸壁の改良に関するものである。
[Detailed Description of the Invention] This invention relates to the improvement of mooring berths, especially mooring berths that can moor ships even in stormy weather.

従来のこの種の岸壁は、一般に、許容変位量が20cm

Conventional quay walls of this type generally have an allowable displacement of 20 cm.
Because it is constructed by arranging multiple fenders of approximately 100 to 100 cm, if the required displacement of the fenders reaches 50 to 100 cm during a typhoon or other stormy weather, there is a risk of damage to the ship or quay. was there.

Therefore, it was common practice to prevent such damage by removing ships from the port during stormy weather, but it takes a lot of time and fuel to remove all ships from the port, and the number of ships increases. In recent years, as the number of ships has increased, there have been problems such as difficulty in securing berthing space outside the port.

On the other hand, as disclosed in Japanese Patent Publication No. 49-25718, there is a constantly inflatable type that has a sufficient range of movement to climb up the berthing wall and land on the slab in synchronization with the movement of the berthed vessel. A fender device has been proposed in which a pneumatic fender and a solid fender that cushions the impact of the ship after the pneumatic fender rides on the slab are provided on the berthing wall. According to the device, most of the large berth energy can be sufficiently and effectively absorbed by the pneumatic fender during the primary berthing of a ship.

However, the pneumatic fender in this conventional technology runs aground on the slab in synchronization with the rising motion of the ship against the quay, and cannot contribute to energy absorption thereafter, so it is particularly difficult to use once the ship is parked. If the fender is repeatedly hit by the quay due to waves or wind during rough weather, pneumatic fenders should be installed.
The situation would be exactly the same as if no protection was provided, and there was a problem in that ships and quays could not be effectively protected.

This invention advantageously solves the problems of the prior art, and makes it possible to reliably protect the side and quay wall not only when the ship comes alongside, but also against collisions with the quay wall while the ship is moored. The purpose is to provide a mooring quay where ships can be moored.

The mooring wharf of this invention has a pneumatic fender whose protrusion height can be changed by supplying and discharging air between multiple fenders with low protruding heights. The pneumatic fender consists of at least a cylindrical body with both end faces closed, and protruding pieces that are integral with the cylindrical body, protrude to both sides of the cylindrical body, and extend in the axial direction. The protruding piece is fixed directly or indirectly to the side wall surface to restrain movement when the pneumatic fender is inflated.

At this mooring quay, during normal times, air is removed from the pneumatic fenders and the energy of coming alongside is absorbed only by multiple fenders with low protruding heights, but in stormy weather, pneumatic fenders are required. By inflating to a protruding height of 50 to 100 cm depending on the ship's height, the pneumatic fender restrains the ship in a predetermined position, not only the primary energy of coming alongside the ship, but also the energy of collision with the quay after mooring. Sufficient absorption at all times provides reliable protection of the sides and quays.

Here, these chains 4 connect the flanges 3b to the wall surface on both sides of the cylindrical main body 3a, and the chains have a length that can effectively restrain the movement of the fender 3 when it expands. Therefore, when the fender 3 is expanded, it can always sufficiently absorb the energy of coming alongside at a predetermined position, and the flange 3b when coming alongside
Stress concentration on the chain 4 is sufficiently alleviated by the plurality of chains 4.

In the mooring quay constructed in this way, during normal times when waves and winds are gentle, air is removed from the pneumatic fender 3 (see Fig. 3a), and the berth load is supported only by the fender 2.

On the other hand, during stormy weather, the pneumatic fender 3 is inflated (see Figure 3), and under the large permissible displacement of the fender 3, the ship is able to reach the quay not only when coming alongside but also after mooring. Even in the event of a collision, the berthing energy is always sufficiently mitigated and absorbed without damaging the ship or quay.

従って、船舶は荒天時にも港外へ退去する必要は全くな

Therefore, there is no need for ships to leave the port even during stormy weather.

Therefore, according to this invention, the pneumatic fender always reliably absorbs energy at a predetermined position against the movement of the ship during stormy weather, so there is no need for the ship to leave the port during stormy weather, and there is no need to leave the port in the event of stormy weather. The problems of fuel wastage and off-harbour berth space are advantageously solved.
