DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floating pier.

[0002]

2. Description of the Related Art Conventional floating piers are moored to piles with chains or ropes, so that even if chains or ropes become loose due to rising and falling of the sea surface, they cannot be automatically absorbed.

[0003]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems and provides a floating pier which can automatically absorb slacks such as chains or ropes even when the sea surface goes up and down. Further, the present invention also provides such a floating pier which can be easily moved.

[0004]

According to the present invention, there is provided a body having a hollow interior for containing air and water so as to float on the sea surface, a weight arranged on the seabed, and an interior arranged between the weight and the body. Is a hollow that accommodates or floats at least air without containing water, and a plurality of sheaves that are fixed to both ends of the main body and are provided on the weight and the float, respectively. And a flexible continuous member capable of maintaining a tensioned state by the buoyancy of the float so as to reciprocate a plurality of times between the floats, the float descends when the sea surface rises, and the float rises when the sea surface descends. An object of the present invention is to provide a floating pier which absorbs slack of a flexible continuous member. The present invention also relates to such a floating pier, wherein the float is fixed to a main body in a state where the sea surface is lowered, and air is supplied to one or both of the main body and the float to discharge water and rise. The present invention also provides a floating pier characterized by being movable as a whole.

Embodiments of the present invention will be described below with reference to the drawings. In the embodiment of the present invention shown in FIGS. 1 to 4, reference numeral 10 denotes a main body of a floating pier according to the present invention, which is configured substantially similarly to a normal floating pier, and has a plurality of hollows, for example, three inside, for safety reasons. There is a closed space 11 for storing air and water. The dimensions of this body are, for example, width 3.
It is made of a steel plate having a length of about 5 m, a length of about 10 m, and a height of about 0.9 m, and is used, for example, in a place where the maximum water depth is about 6.5 m. The dimensions of the body 10 and the maximum water depth used may be different from those described above. Numerals 12 denote connection ports which are connected to a compressed air source via hoses (not shown) to supply air to each space portion 11 and to discharge this air, and can be opened and closed by a stopper 13. I have. Reference numerals 15 denote connection ports through which water is supplied and discharged from a pump through hoses (not shown) into the respective space portions 11, and can be opened and closed by plugs 16. Seawater can be used as the water.

Reference numeral 19 denotes two weights submerged on the sea floor, each having a plurality of sheaves 20 mounted on the upper surface thereof in a single row. The weights 19 may be formed as one piece. Reference numeral 23 denotes a float, which has a structure similar to that of the main body and can supply and discharge air and water, and has a certain degree of buoyancy at all times.
Reference numeral 25 denotes a plurality of sheaves mounted on the lower surface of the float in two rows. Reference numeral 27 denotes a flexible continuous member such as two ropes, which may be made of various fibers, a wire rope, a chain, or the like. 25 are alternately mounted. In this case, the flexible continuous member 27 always expands due to the buoyancy of the float 23.

In the above-mentioned structure, when the tide is high, the main body 10 rises as shown in FIG.
3 falls. Also, at low tide, the main body 10 descends and the float 23 rises as shown in FIG. The rising and falling state is shown by a solid line at high tide and a dashed line at low tide in FIG. When it is necessary to navigate such a floating jetty, the float 23 is fixed to the main body 10 at low tide, and air is supplied while removing water from one or both of the main body 10 and the float 23 to supply the air. Float and tow by another ship.

In the present invention, an opening may be formed at the bottom to allow water to flow into and out of the main body 10, and the amount of water may be adjusted by air. The main body 10 may be configured such that air is always sealed in a part of the plurality of spaces, and air and water are stored in only the other spaces so as to be able to enter and exit. In some cases, a body having only one space is used as the main body 10. Float 23
Can be used as long as it has sufficient buoyancy to tension the flexible continuous member 27, and it may be configured so that only air is stored and hermetically sealed, but not necessarily water. Further, the flexible continuous member 27 may be connected to both sides at one end of the lower surface of the main body 10 to be one, or three or more flexible continuous members 27, for example.
May be used.

[0009]

The present invention has an effect that the slack of the flexible continuous member 27 due to the ebb and flow of the tide is automatically absorbed, and the main body 10 can always be held at a desired position. Further, in the invention as set forth in claim 2, there is an effect that it can be moved more easily.
