BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-functional unloading pier used for unloading work and for mooring a ship therefor.

[0002]

2. Description of the Related Art Conventionally, as a fishing port or a port facility, a jetty is installed projecting from the quay for mooring, unloading, and unloading fishing boats. Breakwaters will be constructed in the port to secure routes and increase quietness against waves. The beach is reclaimed for the purpose of obtaining a working yard, and upright or inclined quays and revetments are constructed as the waterfront facilities. Most of the natural beaches have disappeared due to the construction of facilities in fishing ports and harbor areas. By the way, it is known that small and small organisms that inhabit a large amount of sand and mud on natural beaches promote the purification of seawater by digesting and oxidizing suspended organic matter in the seawater.

[0003]

[Problems to be Solved by the Invention] However, the concentration of suspended organic matter increases as it flows from a river into the bay, and a small amount of sand and mud layer cannot cope with it. This is largely due to the disappearance of natural beaches. On the other hand, a large amount of floating mud floats in the seawater inside and outside the harbor and does not settle and deposit. S. As a (floating suspension), the transparency of seawater is poor. Therefore,
It is possible to create an artificial beach and purify seawater by installing a net-like material that absorbs and fixes floating mud and actively depositing floating mud to form a sand mud layer.

It is an object of the present invention to provide a multi-functional unloading jetty having a sand-mud layer formed below it in order to create an ecosystem of aquatic plants and animals that grow in the sand-mud layer.

[0005]

In order to achieve the above-mentioned object, the present invention is a pier provided for the work of digging or unloading the floor or the floor above the plurality of foundation piles driven into the seabed. Underneath, a net is inclined in each section surrounded by the plurality of foundation piles, and a plurality of nets are attached so as to be in a fault state with each other. The net may be tilted by raising the shore side in a place surrounded by four foundation piles below the water surface and maintaining the shape with a strong rope around the square net.

[0006]

With the above-described structure of the present invention, seawater passes through the net which is a wall in the flow direction, and floating mud floating in the seawater is absorbed and fixed on the net. Then, by repeating the flow, the suspended mud in the seawater in the vicinity is reduced and a sand-mud layer is formed instead. This sand-mud layer is formed on multiple nets to promote the generation of micro and small organisms, and it becomes possible for fish and seafood that feed on the micro and small organisms to gather and live there.

[0007]

Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIG. 1 and FIG. 2, the unloading pier 1 has a pipe-shaped foundation pile 2 which is driven horizontally and vertically into the ground of the seabed at equal intervals. W. L. The upper digit 3 is installed.
A connecting plate 4 is installed at the end of the digit 3 and is connected to the quay.

The four foundation piles 2 forming each section are
L. W. L. A quadrilateral net 6 whose periphery is fixed to a lower position by a guide frame 5 is fixed by a fixture 7 with the quay side higher and the open sea side lower. The nets 6 that are installed so as to be inclined are provided in a multi-tiered manner with a space between each other in the vertical and horizontal directions and in the vertical direction. The net 6 is formed of a synthetic resin in a mesh shape of about 1 mm, and the guide frame 5 may be a strong rope or a vinyl chloride pipe formed in a square shape. Further, the net 6 and the guide frame 5 may be integrally formed.

As described above, the net stretched obliquely between the foundation piles becomes like a wall against the tidal current, so that seawater passes through the net, at which time floating mud in the seawater is absorbed and fixed on the net. To do. Once the floating mud is adsorbed and fixed, the floating mud is adsorbed and fixed one after another on this surface to form a sand mud layer on the net. Further, since the load of sand and mud applied to the net is supported by the guide frame, the net is prevented from being deformed. In this way, the floating mud in the seawater is reduced, and the transparency of the seawater is increased, and the accumulated sand and mud layer creates artificial beaches similar to natural beaches due to the generation of micro and small organisms, and the activity of flora and fauna. Creation of an ecosystem can be expected. Also, the purification of seawater will be promoted by small and small organisms.

[0010]

[Effects of the Invention] Since the present invention is configured as described above, a multi-stage sand-mud layer can be easily formed below the existing or newly constructed unloading jetty, and it is ecological due to the generation of micro and small organisms and food chains. A system can be created. And fine
It is possible to promote purification of seawater by small organisms and increase fishery resources by the fish reef effect. In addition, the construction cost is low because only the net is installed under the unloading jetty.
