Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an improvement of a floating quay, and more specifically, it provides a floating quay suitable for a place where the exclusive area in a port is small and where the tidal level changes relatively widely. It is.

[Conventional technology]

Many of the quays used in the past are shown in Figure 6 (A).
As shown in (II), a structure in which a harbor is dredged and a quay wall 1 having a vertical surface is formed therein is often used. A vessel 2 is moored to this type of quay 1 so as to be perpendicular to the quay, and the quay 1 is set at an appropriate height between the vessel and the top of the quay at high tide level (OWL). has been done. Therefore, at low tide (LWL), the distance l between the ship 2 and the top surface of the quay 1 becomes long, making it difficult to handle cargo. It becomes substantially difficult to utilize this quay 1, and the time during which this quay 1 can be effectively used is limited.

As shown in FIG. 7, a floating body 3 is extended perpendicularly to the quay wall 1 and moored with a mooring cable 4, and a ramp 5 is provided between the floating body 3 and the quay wall 1. A connected floating pier is proposed.

At this floating pier, a ship 2 is moored along a floating body 3, but in the case of this floating pier, even if the tide level changes, the floating body 3 follows it, and only the inclination angle of the ramp 5 changes. This has the advantage that cargo handling is not affected by the tide level.

However, since the floating body 3 is extended orthogonally to the quay wall 1 and the mooring cables 4 are spread out and stretched laterally, the area occupied by the floating pier within the harbor becomes large, and it cannot be used in a narrow harbor. Furthermore, since the ships 2 are moored along both sides of the floating body 3, there is a problem that the number of ships 2 that can be moored is small, and that it cannot be used effectively unless the port is very large.

As a method that does not use floating bodies in ports with large tidal differences, the quay is formed into a staircase shape as shown in Figure 8, and cargo is handled using appropriate steps of the staircase according to changes in the tide level. There is something I did.

However, in the case of a quay with this structure, extensive dredging and ground improvement work are required, resulting in a long construction period and an increase in construction costs.

[Purpose of the invention]

The present invention was obtained in order to eliminate the disadvantages of quays constructed in places with large tidal differences, and the purpose of the present invention is to eliminate the disadvantages of quays constructed in places with large tidal differences. To provide a floating quay that does not require much construction cost.

Furthermore, another object is to provide a floating quay that can easily convert existing quays and seawalls into mooring facilities and that requires a short construction period.

[Summary of the invention]

The configuration of the present invention for achieving the above object includes a quay, a floating body provided along the quay, and a bridge connecting the floating body and the quay, and the bridge and the floating body are connected by a hinge. , a floating quay wall configured to guide and moor the floating body up and down according to changes in the tide level.

That is, the present invention is characterized in that the floating body is arranged parallel to the quay and the floating body is moored using a bridge. Therefore, another feature is that the bridge and the quay are connected by hinges, and the bridge and the floating body are connected by hinges.

Since the floating body constitutes a substantial quay, it must be sufficiently long in relation to its width, have sufficient area and buoyancy for cargo handling, and be sufficiently safe against sea conditions such as corrosion and typhoons. It is necessary to have

In reality, this floating body is often made of concrete.

The bridge in the present invention is not just a bridge, but constitutes an important member for mooring a floating body. Therefore, it goes without saying that the crossing bridge has sufficient strength to support the movement of heavy vehicles, but it also resists the forces that cause the floating body to move away from the quay, the force that approaches the quay, or the force that causes the floating body to move along the quay. It is preferable to generate a mooring force sufficient to withstand external forces such as.

It is preferable that the mooring force of the floating body is exerted only by the bridge, but
If the bridge itself has such strength, if there are problems such as the bridge becoming larger or the joint between the bridge and the quay wall needing to be reinforced, it may be necessary to strengthen the pillars that moor the floating body. Can be used as a supplement.

The connecting part between the bridge and the floating body that moves up and down as the tide level changes will move relatively, but the connecting part needs to adopt a structure that allows the floating body to be moored while allowing this movement. be.

〔Example〕

Next, the present invention will be described in detail with reference to the drawings.

In Figures 1 to 3, an abutment 11 is extended from an existing quay 10, one end A of a bridge 12 is connected to this abutment 11 by a hinge, and the other end B of this bridge 12 is connected to a floating body 13 via a hinge. are doing.

The other end B portion is shown in FIGS. 4 and 5,
In this part, a guide rail 14 is provided on the floating body 13, and a roller 1 is supported by a shaft 15 provided at the end of the bridge 12.
6 is guided by the guide rail 14.

The shaft 15 is provided with a plurality of sliding bearing plates 17, which allow the floating body 1 to move laterally without allowing the floating body 12 to move laterally.
3 supports W12.

Further, an apron 18 is provided between the end of the bridge 12 and the upper surface of the floating body 13 to eliminate a difference in level.

The floating body 13 approaches or moves away from the existing quay 10 due to the current flowing in the bay, and a fender 20 is provided on the surface of the floating body 13 facing the existing quay 10.

A fender 21 is also provided on the side where the ship berths.

The floating quay wall configured as described above allows the floating body 13 to move up and down between 13 and 13'' in Fig. 2 according to fluctuations in the tide level, and allows ships to berth and carry out cargo handling regardless of fluctuations in the tide level. can.

〔Effect of the invention〕

The floating quay according to the present invention is composed of a quay, a floating body provided along the quay, and a bridge connecting the floating body and the quay. Since it is configured to be guided and moored, the following effects can be achieved.

(11) Even if the tide level fluctuates, the floating body follows it, so cargo handling can be carried out despite the fluctuations in the tide level.

(2) Since the exclusive area within the port is small and there is no need for mooring lines inside the port, there are no structures that will obstruct moored ships or ships navigating within the port, so there is no impact on these ships. do not have.

(3) Even without large-scale on-site construction such as dredging and reclamation,
It can be converted into a mooring facility using existing quays and seawalls, and the construction period is short and economical.

(4) Since the load acting on the floating body is transmitted to the quay side through the fender, there is no need for a large mooring device, and since the bridge also serves as a mooring device, mooring cables (chains) on the quay side are used.
The mooring operation is simple and does not interfere with ships, etc.
