Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a mooring device for mooring ships, and is particularly suitable for mooring small ships in sea areas with large tidal level differences. Regarding the retention device.

(Prior art) The tidal level difference varies greatly depending on the sea area, but for example, on the coast of Kyushu, there are places where it reaches 6M. On a coast with such a large tidal level difference, if you moor a small boat on the quay and try to land fish, etc., at low tide there will be a drop of more than 4 meters between the top of the quay and the boat. Landing it would be completely impossible.

Therefore, conventionally, as shown in FIG. 5, for example, a pontoon 2 is floated on the sea away from a quay 1, and a floating bridge 4 is constructed by building a bridge 3 between the pontoon 2 and the quay 1. Either you can place a boat next to Pontoon 2, unload the cargo onto Pontoon 2, and then use a cart or the like to cross the bridge 3 and unload the cargo, or as shown in Fig. Either a ramp 5 is extended and a ship is placed next to the ramp 5 to unload cargo, or a stairway 6 is installed by cutting out a predetermined area of the quay 1 as shown in Fig. 7a and b. A ship was placed next to the stairs 6 and the cargo was unloaded using stairs of an appropriate height.

(Problems that the invention attempts to solve) However, in the case of the floating bridge 4 (Fig. 5), there is a difficulty in anchoring the pontoon 2, and large swinging of the pontoon is unavoidable. (Fig. 6) or the stairs 6 (Fig. 7), the surface became slippery due to the adhesion of seaweed, etc., and both cases involved dangerous work.

In addition, the floating bridge 4 and the jetty-type ramp 5 protrude greatly into the port, narrowing the harbor area.Furthermore, the ramp 5 and the stairs 6 have cargo unloading points in one place corresponding to the tide level. Because of the limited number of locations, there was a problem that there was a lot of wasted space, and none of them could be used as fundamental countermeasures.

(Means for solving the problems) In order to solve the above-mentioned conventional problems, the present invention
The gist is that a notch is provided in at least one section of the quay, a pontoon is housed in the notch, and a bridge is constructed between the pontoon and the quay.

(Function) In the mooring device with the above configuration, by storing the pontoon in the notch provided in the quay wall, it becomes possible to suppress the swinging of the pontoon on the quay wall itself, which is coupled with ensuring a working surface that does not get wet with seawater. This will enable safe work to be established. In addition, it is possible to eliminate a protruding part from the front of the quay that interferes with the harbor anchorage, and the entire surface of the pontoon can be used as a work surface, increasing its utility value.

(Example) Hereinafter, an example of the present invention will be described based on the accompanying drawings.

In Figures 1 to 4, 11 is a quay;
The quay wall 11 has a plurality of notches 12 at a predetermined pitch.
12... are provided. On both sides of each notch 12, caissons 13 and 1 forming part of the quay wall 11 are provided.
3 is installed. A part of this caisson 13 protrudes into the notch 12 on the sea side to form a jetty 13a.
is finished with an irregular cross section that is wider at the back. Reference numeral 14 denotes a pontoon that is accommodated in the notch 12 and floats on the sea surface, and has a cross-sectional shape similar to the cross-sectional shape of the notch 12, and has protrusions 1 provided on both sides of the pontoon.
4a is located at the rear of the jetty portion 13a of the caisson 13. The pontoon 14 also includes a number of fenders 15 on its sides, the fenders 15
is in sliding contact with the quay 11 and the caisson 13. Reference numeral 16 denotes a bridge built between the quay wall 11 and the pontoon 14, one end of which is fixed to the quay wall 11 with a hinge (not shown), and the other end slidably attached to a pedestal 17 provided on the pontoon 14. Supported.

Here, the pontoon 14 is made of concrete, for example, and has a total length of 60M, a total width of 10M,
It is a small ship with a total height of about 3 meters.
This allows for multiple anchorages.

With such a configuration, the pontoon 14 moves up and down within the notch 12 according to the tide level, and as a result, the pontoon 14 moves up and down within the notch 12 in accordance with the tide level, and as a result, the pontoon 14 moves up and down in the notch 12 in accordance with the tide level, and as a result, both at low tide (Fig. 3) and at high tide (Fig. 4),
The relative level between pontoon 14 and shippaku 18 hardly changes, and the relative level from shippaku 18 to pontoon 14
On the other hand, cargo unloaded onto the pontoon 14 can be unloaded onto the quay 11 using the bridge 16 at low tide, and at high tide, the level of the pontoon 14 is lowered. Since it goes up, it is possible to land directly on the quay 11 without using the bridge 16. Of course, you can also use Ferry 16 during high tide. However, the pontoon 14 is always connected to the quay 11 and the caisson 1.
3, and large swings are regulated.
The landing can be carried out without any dangerous work.

In the above embodiment, the caisson 13 was used to specify the cross-sectional shape of the notch 12, but it goes without saying that the irregularly shaped notch 12 may be formed by directly notching the quay 11 without using the caisson 13. be. Further, the number of notches 12 provided in the quay wall 11, that is, the number of pontoons 14, is not particularly limited, and one or more may be provided. Further, the bridge 16 in the above embodiment can be replaced with a conveyor.

(Effects of the invention) As explained in detail above, in the mooring device according to the present invention, the pontoon is housed in a notch provided in the quay wall, so the rocking of the pontoon can be suppressed by the quay wall itself. This has the effect of ensuring safe work by ensuring a work surface that does not get wet with seawater. Furthermore, it is possible to eliminate a protruding part from the front of the quay that interferes with the harbor anchorage, and the entire surface of the pontoon can be used as a working surface, which has the effect of significantly improving the utility value as a whole.
