Description

Artificial reef using suction pile {ARTIFICIAL REEFS USING SUCTION PILE}

The present invention relates to an artificial reef, and more particularly, to an artificial reef installed by using a suction pile in a soft ground of the seabed.

In general, artificial reefs are artificial structures that are installed on the coast or near the sea to provide spawning and habitat space for marine life and to provide shelter for young fish to secure fishery resources of coastal fisheries.

Artificial reefs are produced separately from the ground and dropped into the sea to be installed on the ground undersea.

However, the surface of the undersea ground where the artificial reefs are installed is often weak due to high water content, and in these places, some of the artificial reefs are buried in the ground by the weight of the artificial reefs. In addition, the artificial reef is moved by the generation of currents or vortices to move away from the original position or fall, there was a problem that can not function as a fish.

Thus, in order to solve the burial due to settlement of the above problems, artificial ground for soft ground was developed, the prior art is disclosed in the Republic of Korea Utility Model Registration No. 0176858.

According to the prior art, by attaching a support plate having an area much larger than that of the artificial reef to the artificial reef, and by allowing the support plate to be supported on the soft ground, the pressure increase in the ground is reduced to prevent the artificial reef from being buried in the soft ground. It was.

However, the prior art can partially prevent the settlement of artificial reefs due to the support plate having an area larger than the area of artificial reefs, but because it is not fixed to the ground by a separate fixing means horizontal by strong current flows such as typhoons and swells There is still a fear of movement or overturning, and there is still a fear of burial of artificial reefs by the introduction of pebbles, sand, etc. in the undersea into the backing plate by currents or vortices.

In addition, a bent surface was formed at the edge of the support plate to prevent the ingress of gravel and sand into the support plate, but if the height of the bent surface was set to be high at random to prevent the ingress of gravel and sand, There was a problem that the inflow path is blocked and cannot function as an artificial reef.

On the other hand, when the artificial reefs are installed on the inclined soft ground, the support plate is inclined, so it is easy to pull in gravel, sand, etc., and there is still a possibility that the artificial reefs are buried when the seabed slope is partially destroyed.

The present invention is to solve the problems of the prior art, an object of the present invention provides an artificial reef using a suction pile that can be firmly fixed and prevent the movement, fall and buried artificial reef by sea current or vortex on the sea bottom It's there.

The present invention for achieving the above object is a base plate; A fishery unit stacked on an upper surface of the base plate and providing scattering and habitat space for marine life; And fixing means for fixing the base plate to the sea bottom.

The fixing means is coupled to the base plate, the suction pile having a vacuum chamber which is piled on the sea bottom surface and prevented from being taken out by an external force; And a valve unit provided in the suction pile to blow out the air in the vacuum chamber.

The base plate extends from an edge so as to be inclined upwardly with respect to the upper surface of the base plate so that the eocho units stacked on the edge of the base plate are inclined toward the center of the base plate to separate the eocho units from the base plate. An inclined wall for preventing is provided.

According to the present invention, the suction plate fixing the base plate on which the reef unit and the forced reef structure are to be stacked is not drawn out by the vacuum pressure and frictional force of the inner chamber during rapid upward movement of the reef by strong currents and vortices. It is firmly fixed to the bottom of the sea. In addition, by installing the suction pile, the settlement is significantly reduced by the frictional force with the subsea ground on the inner and outer friction surfaces, and there is a key block effect that prevents horizontal movement.

In addition, when installing the reefs in the inclined seabed form, the length of the suction pile is sufficient and the base plate is separated from the bottom, so that the base plate and the reef unit can be installed properly without being inclined, and the seabed ground is partially destroyed. In this case, there is an effect of preventing the investment.

Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of the present invention.

1 shows a structure of an artificial reef using a suction pile according to the present invention.

Referring to FIG. 1, the present embodiment includes a base plate 10, a reef unit 20 stacked on the base plate to provide scattering and habitat space for marine life, and fixing means for fixing the base plate to the sea bottom ( 30).

The base plate 10 has a sufficient area so that a large number of fishery units 20 can be stacked on the upper surface thereof, and is formed in a flat plate shape.

Echo unit 20 is formed in the shape of a rectangular parallelepiped, the interior space is formed for the spawning and habitat of marine life inside, the habitat space on the meat surface so that marine life can freely travel to the habitat space (21) Forced reefs with a fishing 22 penetrating outward from 21 are used.

In the present embodiment, the fish herb unit is illustrated in the shape of a rectangular parallelepiped, but the present invention is not limited thereto, and a habitat space and a fish that communicates with the outside space may be formed.

2 and 3 illustrate another embodiment of the base plate. Another embodiment of the base plate 10 is provided with an inclined wall 11 which extends a predetermined distance from the edge of the base plate and inclined upward at a predetermined inclination angle with respect to the upper surface of the base plate 10. This is such that the eocho unit 20 stacked on the edge of the base plate 10 is inclined toward the center of the base plate 10 by the inclined wall (11). Therefore, the fish paste unit 20 laminated | stacked on the edge of the base board 10 is laminated | stacked on the base board 10 more stably.

In addition, in the lamination process of the eocho unit 20, it is possible to minimize the eocho unit 20 that is separated from the base plate 10 by the current and vortex.

Referring to Figures 1 to 3, the fixing means 30 is coupled to the base plate 10, the pile is piled on the seabed ground to prevent it from being taken out of the ground by external forces (waves, currents, buoyancy, etc.) It consists of a file 30 '.

The suction pile 30 ′ has a circular pipe shape, one side of which is opened, and the other side of the suction pile 30 ′ is shielded to form a vacuum chamber 33 therein. The suction pile 30 'is provided with a valve unit for taking out air and seawater in the vacuum chamber 33.

The suction pile 30 ′ is opened at one side of the suction pile 30 ′. When the suction pile 30 'is forced to discharge air and seawater in the vacuum chamber 33 of the suction pile 30' in a state in which one side of the suction pile is in close contact with the ground, the internal vacuum of the vacuum chamber 33 It is drawn into the ground and fixed by the pressure difference between pneumatic and external seawater pressure.

The valve unit consists of an air outlet 31 and a check valve 32 provided in the air outlet 31.

The coupling of the base plate 10 and the suction pile 30 'is made by welding or mutual coupling of the bolt 41 and the nut 42.

When a bolt and a nut are used, a flange 43 is formed on the upper edge of the shielded suction pile 30 'to be in close contact with the bottom surface of the base plate 10, and the edge 43 and the flange 43 of the flange 43 are formed. The base plate 10 to be in close contact with the bolt hole 44 to which the bolt 41 is fitted is formed. At the upper end of the bolt hole 44 formed in the base plate 10, the head inlet groove 45 having the inner diameter of the bolt hole 44 extended so that the head of the bolt 41 enters is concentric with the bolt hole 44. Formed.

Hereinafter, the operation and effects of the present embodiment configured as described above will be described.

The suction pile 30 'is positioned at a predetermined position of the seabed ground by a crane (not shown) and descends. The lowering is performed until one open side of the suction pile 30 'is in close contact with the ground and closed.

3, the vacuum of the suction pile 30 ′ through the air outlet 31 of the suction pile 30 ′ using the suction pump 50 located on the land or work line 60. The seawater and air introduced into the chamber 33 are forcedly discharged. At this time, the internal pressure in the vacuum chamber 33 of the suction pile 30 'is lowered and the suction pile 30' is drawn into the ground and fixed by the hydraulic pressure acting as a larger pressure than the internal pressure.

The suction of the suction pile 30 'is drawn until the pressure inside and outside the vacuum chamber 33 is kept the same. The pulling distance of the suction pile 30 'is possible by internal pressure control. Thus, the separation distance between the base plate 10 and the ground installed on the upper end of the suction pile 30 'can be adjusted.

Therefore, by adjusting the pulling distance of each suction pile 30 ', the base plate 10 can be provided flat even in the seabed which has an uneven surface.

The suction pile 30 'prevents the reefs from being pulled out by the sub-friction force acting downward and the vacuum pressure of the inner chamber when the base plate of the reef rapidly moves upward by the action of the current or the vortex. In addition, the frictional force between the suction pile 30 'and the inner / outer friction surface and the seabed ground not only significantly reduces the settlement of the grassland by its own weight, but also penetrates into the seabed ground and acts as a key block of the grassland. To prevent horizontal movement.

Thus, the base plate 10 coupled to the suction pile 30 'is firmly fixed without being settled, moved horizontally, or conducted by current or vortex. In addition, when the base plate 10 is installed at a predetermined distance from the ground, gravel or sand of the ground does not flow into the base plate 10 due to currents or vortices. Therefore, the echo unit 20 does not move or bury in spite of various instability factors that may occur on the sea floor, and does not fall by a large wave force, thereby making it possible to function properly.

Embodiment of the present invention described above should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art can change and change the technical idea of the present invention in various forms.
