Description

The present invention is a mooring pile in which a floating body that moves up and down in response to fluctuations in the sea surface or water surface, such as a floating pier for mooring a ship or a floating body in which a sewage treatment device is suspended and installed in a sewage pond, is fixed to the seabed or the like. Regarding a floating body mooring device for mooring.

When a ship is moored on a quay, the height of the quay is constant, whereas the height position of the ship fluctuates according to the tide level due to the rise and fall of the sea surface, or constantly fluctuates depending on the wave height. For this reason, by mooring a ship at a floating pier and arranging a crossing bridge between the floating pier and the quay, crew members such as sailors and passengers can get on and off the ship smoothly. That is, as shown in FIG. 7, the floating pier 2 is arranged at a position appropriately separated from the quay 1, and the quay 1 and the floating pier 2 are connected by a crossing bridge 3. Vessel S is moored at the floating pier 2. Since the floating pier 2 is floating on the sea surface, it moves up and down due to fluctuations in the tide level and wave height, and its upper surface is always at a constant height with the sea surface. Therefore, the crew of the ship S can smoothly get on and off the floating pier 2. The end of the pier 3 on the floating pier 2 side, which is hung between the floating pier 2 and the quay 1, is moved up and down together with the floating pier 3 so that the erected state with the quay 1 is maintained. , The occupants are allowed to come and go between the quay 1 and the floating pier 2 by the crossing bridge 3.

Since it is inconvenient if the crossing bridge 3 is separated from the quay 1 and the floating pier 2, the floating pier 2 must be in a fixed position with respect to the quay 1. Therefore, the floating pier 2 is arranged by connecting the mooring device 5 to four mooring piles 4 having a substantially rectangular cross section, which are fixedly installed on the seabed so as to correspond to the corners of the floating pier 2. Has been done. As a mooring device for this purpose, there are various devices described in Patent Documents 1 to 3. This type of mooring device is attached to the floating pier 2 in connection with the mooring pile 4.

FIG. 8 is a side view showing an example of the mooring device 5, in which notches are formed at the four corners of the floating pier 2 having a substantially rectangular plane shape in a substantially rectangular shape, and the sides of the square are formed on the side surfaces of the floating pier 2. A mooring device 5 is attached to each of the side portions. The mooring device 5 is provided with a guide roller 5b rotatably provided on the gantry 5c with the horizontal direction as the axis 5a, and the gantry 5c has a structure in which a cushioning member 5d is interposed. The guide roller 5b is arranged so as to come into contact with the side surface of the mooring pile 4.

The movement of the floating pier 2 in the sea surface is restrained by the mooring pile 4 via the mooring device 5, and the guide roller 5b is the mooring pile 4 against the rise and fall of the sea surface due to a change in the tide level or waves. The floating pier 2 is allowed to move up and down by guiding while rotating along the side surface of the pier.

By the way, in response to changes in the tide level due to ebb and flow during normal times, as described above, the floating pier 2 floats on the sea surface while being restrained by the mooring pile 4 by the mooring device 5, and the sea level rises and falls due to changes in the tide level and waves. There is no risk of damage to the floating pier 2 and the mooring pile 4. On the other hand, in abnormal weather such as a storm caused by a typhoon, the behavior of the floating pier 2 becomes violent, so that the mooring device 5 may collide violently with the mooring pile 4 and the mooring device 5 may be damaged. In such a case, it is preferable to release the connection with the mooring pile 4 so that the floating pier 2 can be moved to another place so as to be released from the restraint by the mooring pile 4.

However, the conventional mooring device cannot release the connection with the floating pier, and the floating pier cannot be released from the restraint by the mooring pile unless the floating pier is disassembled. In addition, there is one equipped with a structure in which a chain fixed to the floating pier is wound around the mooring pile, and the connection between the floating pier and the mooring pile is released by unwinding the chain to float. There is a mooring device that allows the pier to be separated, but the sway of the floating pier in normal times becomes large and the smoothness of work on the floating pier is impaired, or the chain is constantly rubbing the mooring pile. Therefore, there is a possibility that problems such as severe damage to the mooring pile may occur.
