Description

[Detailed description of the invention] The present invention relates to a method of constructing a mooring pier.

For example, if there is no suitable port on the coastline where a ship is trying to berth, building a port on that coastline would take a long time and would not be useful in an emergency.

Furthermore, even if cargo is only to be unloaded and unloaded for a certain period of time, building a port will not be cost-effective. Therefore, the present invention proposes a method of constructing a mooring pier that is most suitable for such cases.

Hereinafter, one embodiment of the present invention will be described based on the drawings. This embodiment relates to a pier for a slurry carrier 1, in which 2 is a mooring pier, which includes a pier main body 3 that can be floated on the sea surface W, and four through holes formed at the four corners of the pier main body 3. Each pillar 4 is inserted into the pillar 4 so that it can be raised and lowered, and the pinion 6 that meshes with a rack 5 disposed along the longitudinal direction of each pillar 4 on the outer circumferential surface of each pillar 4 is rotated in the forward and reverse directions. and a sinking weight 9 movably mounted on each of the columns 4 and supported by a stopper 8 at the lower end of each column 4. 10
11 is a pair of foldable pipe joints arranged at the center of the upper surface of the pier body 3, and 11 is a flexible hose connected to the base of each joint 10, the tip of which is connected to the base of the pipe from the land 12 through the seabed. It is connected to the tip of the slurry pipe 13.

Note that this flexible hose 11 is stored within the pier main body 3 when the pier 2 is sailing. 14 is an on-off valve provided at the tip of the slurry pipe 13, and 15 is a rubber fender provided on the side of the pier body 3 facing the slurry carrier.

Reference numeral 16 denotes a mooring barge, which has almost the same structure as the mooring pier 2, and includes a barge main body 17, a stopper 18, a support column 20 with a rack 19, and a drive that rotates the pinion 21 meshing with the rack 19 in the forward and reverse directions. It has a device 22 and a sinking bell 23, and its function is almost the same as that of the mooring pier 2.

24 is a mooring rope for mooring the carrier ship 1 to each barge body 17.

Based on the above configuration, the mooring pier 2 and the mooring barge 16
We will explain how to construct it. First, the drive device 7 is operated to raise each support column 4 via the pinion 6 and rack 5, and the mooring pier 2 is placed in the state shown in FIG. In this case, the sinker 9 is supported by the stopper 8 and lifted together with the support column 4, and is positioned near the bottom surface of the pier body 3. Similarly, each support 20 of each mooring barge 16 is raised. Next, the mooring pier 2 and the mooring barge 16 are navigated to a predetermined location, that is, near the tip of the slurry pipe 13. Next, each drive device 7, 22 is operated to lower each support column 4, 20, and each sinker 9, 23 is placed on the seabed. The ship body 17 is pulled up above the sea level W. Next, the tip of the flexible hose 11 is connected to the tip of the slurry pipe 13, and the valve 14 is opened. This completes the construction. Next, the slurry carrier 1 is moored to the mooring pier 2, and the bow and stern of the carrier 1 are moored to each mooring barge 16 with the mooring elements 24, and the foldable pipe joint 1
0 is connected to the manifold la of the carrier 1, and slurry is loaded into the carrier 1 via the slurry pipe 13, flexible hose 11, and the piping joint 10. Next, when moving the mooring pier 2 and the mooring barge 16, the pinions 6, 21 are driven by the drive devices 7, 22.
It is only necessary to pull up the columns 4, 20 via the racks 5, 19. As a result, the above poem # Hishihashi Bridge 2 and Barge 1
6 is landed on the water, and each sinking key 9, 23 hits the stopper 8, 18.
It is supported by and pulled up together with each pillar 4, 20.
As shown in Fig. 4, each support 4, 20 is pulled up sufficiently,
Once the flexible hose 11 is stored in the pier main body 3, it may be sailed to a predetermined location. In the above embodiment, the racks 5, 19 and the pinions 6, 321 support the supports 4, 2
In this embodiment, the robot is raised and lowered, but it may be raised and lowered using a wire rope and a winch device.

As described above, according to the method for constructing a mooring pier of the present invention, the pier body is floated on the sea, each support is raised by a drive device, the mooring pier is then sailed to a predetermined location, and then The structure can be constructed in an extremely short period of time, as each support is lowered by a driving system to lower each sinker to the seabed, and the lower end of each support is pressed against the seabed to raise the pier above the sea surface. It is also useful in emergency situations. In addition, since it can be moved freely anywhere by simply pulling up each support, it is most suitable when the period for lifting and unloading cargo is only for a certain period of time.

Claims (1)

[Claims] 1. A pier body that can be floated on the sea, struts each inserted into a plurality of through holes formed in the pier body so as to be able to rise and fall freely, and a drive device that raises and lowers each of the struts;
The main body of the mooring pier, which has a sinker that is movably fitted onto each of the above-mentioned supports and is supported by a stopper at the lower end of each of the supports, is floated on the sea, and each support is raised by a drive device. The mooring pier is then brought to a designated location by navigation, and then each support is lowered by the drive device to place each sinker on the seabed, and the lower end of each support is pressed against the seabed to raise the pier body above the sea surface.
