[Problems to be Solved by the Invention] By the way, in the above-mentioned public utility model gazettes, since the steel pipe piles for mooring project upward from the floating pier, the surrounding landscape is improved. There is a problem that significantly impairs it.

Further, since the steel pipe pile for mooring is only supported by (the horizontal roller of) the mooring metal fitting on the side of the floating pier,
Although the floating pier moves up and down depending on the tide level and waves, it cannot cope with swings in each direction, and there is a problem in that the mooring metal parts are easily damaged.

Further, when the floating pier moves up and down due to the tide level or waves, the mooring metal fittings (horizontal rollers) on the floating pier side rub against the steel pipe piles for mooring. Even for steel pipe piles for mooring (horizontal roller of mooring bracket)
Even if the steel pipe pile for mooring is coated with a synthetic resin thin film such as polyethylene on its outer periphery, the horizontal anti-corrosion coating of the mooring metal fitting (horizontal roll of -) Due to rubbing against and splashing, the coating is significantly deteriorated in about 1 to 2 years and peeled off,
There is a problem that rust is generated remarkably and maintenance costs are worried.

[0006]

The present invention has been made in order to solve the above-mentioned problems of the prior art. The first gist of the present invention is that the lower part of the floating pier is provided in the longitudinal direction of the outer peripheral surface. In a mooring device for a floating pier, a steel pipe provided with a sliding member for vertical movement is hung vertically via a universal joint, and the steel pipe is inserted and inserted into an underwater steel pipe pile for a guide placed at the bottom of the water.

The second gist of the present invention is as follows.
At the bottom of the floating pier, a steel pipe provided with a sliding member for vertical movement in the vertical direction of the outer peripheral surface so as to project inward from the outer peripheral surface is hung vertically through a universal joint, and a guide is placed in the steel pipe at the bottom of the water. It is located on the mooring device of a floating pier with submersible steel pipe piles inserted.

[0008]

As described above, a steel pipe having a sliding member for vertical movement in the vertical direction on the outer peripheral surface is vertically provided at the lower part of the floating pier via a universal joint, and this steel pipe is cast on the bottom of the water for guiding. Either be inserted into the middle steel pipe pile, or at the bottom of the floating pier, a steel pipe provided with a sliding member for vertical movement in the vertical direction on the outer peripheral surface so as to project inward from the outer peripheral surface is hung vertically via a universal joint. By inserting the underwater steel pipe pile for guides placed on the bottom of the water into this steel pipe, the so-called mooring steel pipe pile does not project from the water, so the surrounding landscape is not impaired and the floating pier is , Through the steel pipe on the side of the floating pier, it moves up and down with respect to the underwater steel pipe pile for the guide depending on the tide level and waves, and the universal joint can respond to rocking in each direction. Above the steel pipe pile Although it moves up and down through the sliding member for motion, since the rubbing between the underwater steel pipe pile for guide and the sliding member for up and down movement is performed in water, the water plays a role of lubrication and the corrosion-preventive life of the underwater steel pipe pile for guide is improved. Since it can be extended and has a double pipe structure of a steel pipe and an underwater steel pipe pile for guide, the mooring strength can be improved.

1 is a perspective view showing a first embodiment of the present invention, in which a universal joint is provided at a lower portion of a floating pier 1 with a steel pipe 2 provided with a vertical sliding member 2a for vertical movement. 3, the steel pipe 2 is inserted into a guide underwater steel pipe pile 4 placed on the bottom of the water to construct a mooring device for the floating pier 1.

The vertical sliding member 2a may be a horizontal roller as shown in FIG. 1 or a sliding bearing (not shown).

FIG. 2 is a perspective view showing an essential part of a second embodiment of the present invention, in which a steel pipe 2 provided with a vertical sliding member 2a vertically protruding from the outer peripheral surface so as to project inward from the outer peripheral surface. −
The mooring device for the floating pier 1 is constructed by vertically arranging the monkey joint 3 through the monkey joint 3 and inserting the underwater steel pipe pile 4 for guide, which is placed at the bottom of the water, into the steel pipe 2.

It should be noted that a protective member having corrosion resistance and resistance is provided at least at a required length portion of the underwater steel pipe pile 4 for guide which is in contact with the sliding member 2a for vertical movement, or the sliding member 2a for vertical movement is provided with corrosion resistance and strength. By using a non-metallic material having properties, the corrosion prevention life of the underwater steel pipe pile 4 for a guide can be maintained for a longer period of time.

[0013]

As described above, according to the present invention, a steel pipe provided with a sliding member for vertical movement in the vertical direction on the outer peripheral surface is vertically provided at the bottom of the floating pier via a universal joint, and this steel pipe is attached to the bottom of the water. It is either inserted into the driven submerged steel pipe pile for guides, or a steel pipe provided with a sliding member for vertical movement in the vertical direction on the outer peripheral surface so as to project inward from the outer peripheral surface at the bottom of the floating pier.
By vertically inserting it through a monkey joint and inserting an underwater steel pipe pile for guides placed at the bottom of the water into this steel pipe, the so-called mooring steel pipe pile does not protrude from the water, so the surrounding landscape can be improved. In addition, the floating pier can move up and down by the tide level and waves with respect to the underwater steel pipe pile for guide through the steel pipe on the side of the floating pier, and the universal joint can respond to swing in each direction. Further, the steel pipe moves up and down with respect to the underwater steel pipe pile for guide through the sliding member for vertical movement, but since the rubbing between the underwater steel pipe pile for guide and the sliding member for vertical movement is performed in water, It plays the role of lubrication, and can extend the anticorrosion life of the underwater steel pipe pile for guides, and further, because of the double structure of the steel pipe and the underwater steel pipe pile for guides, the mooring strength can be improved.
