Referring to the operation and effect of the marine structure installation anchor and a marine structure installation method using the present invention configured as described above are as follows.

Offshore structure installation anchor (1) applied to the present invention is installed in order to prevent the spread of marine pollution occurring in the dredging, reclamation, construction of the construction of the port construction, the anti-fouling film and sea-structure, the farm, installation, buoyancy buoyancy buoyancy tank The present invention relates to an anchor for firmly fixing a back and an installation method using the same, and to improve construction, stability, economy, and installation method.

To explain this in more detail, the anchor 1 applied to the present invention is used by being installed in the seabed depth by the membrane dropping method as shown in FIG. 5, in particular, between the two anchors 1 which are dug into the seabed depth. An installation step of the horizontal main wire 7 connected to the length in the longitudinal direction and installed on the sea floor; A plurality of vertical main wires (6) installed at a predetermined interval so as to have a cross shape with the horizontal main wires (7) and installed between both anchors (1) which are deeply dug into the seabed; The installation step of the center wire (4) which is installed vertically connected to the middle of the intersection of the horizontal main wire (7) and the vertical main wire (6) and installed at the bottom of the anti-fouling film (3); Connecting subwires 5 which are installed at both sides of the lower end of the floating body 2 to the longitudinal main wires 6, respectively; And a supporting rope 9 installed at a lower end of the floating body to support the floating body and the antifouling film together, and opposite ends of the rope are connected with the horizontal main wires to protect the antifouling film. By the step; to provide a marine structure installation method using the anchor for the marine structure installation.

In more detail, after connecting the wire to the anchor (1) applied to the present invention, if the first drop into the sea automatically anchor 10 will be dug into the seabed depth to have a resistance.

That is, the anchor (1) applied to the present invention is to touch the sea floor while descending vertically deep into the sea, as shown in Figure 4 (a), wherein the shank 85 is one of the one side or the other side, such as an imaginary line It is also rotated in the direction is inclined, it is rotated about the central axis 52 of the connection portion 50.

In the above state, when the shank 85 is pulled to the anchor 1 in a state in which the shank 85 is inclined to one side on the sea bottom, the anchor 1 is easily dug into the sea bottom. I get in and get stuck.

That is, as shown in Figure 4 (c) subsea ground inserting portion 60 and the subsea sub-ground inserting portion 80 is to be dug into the seabed to get stuck, in particular the point is pointed and the inclined surface 64 on one side When the inner blade portion 61 is formed to dig into the bottom of the seabed, the outer wing portion 62 is also sharply formed at the bottom of the bottom so as to dig deep into the bottom of the seabed. At this time, since the weight of the anchor (1) is made of iron material, it is formed to a certain weight so that it can easily penetrate into the general sea floor, but if the state of the sea floor (sand, gravel layer, etc.) is hard and not easily get stuck The anchor 1 may be easily manufactured by putting a heavy weight, and in this case, the weight 73 may be put into the body portion 71 of the weight generating frame 70 to make the overall weight of the anchor 1 easy. Allow them to dig into the sea floor. The weight body 73 is generally preferably filled with mortar, but, of course, a heavy material may be filled in addition to the mortar as necessary.

In addition, the weight body production frame 70 is provided to protrude more than the width of the shank 85 in addition to the above-described effect, so that the subsea ground inserting portion 60 is placed to be inclined on the bottom of the sea floor, so that it can dig into the seabed depth. Will provide a role.

As described above, the anchor 1 of the present invention can be transmissive without the need for meticulous technology in the conventional anchoring, of course, it does not need to be confirmed in the water, and because it is not a double-edged anchor, it is also a bottom of a work boat, such as a fishing boat, even in a low depth region. There is no fear of damage.

And ribs 65 protruding on one side of both outer wing portion 62 prevents the anchor 1 from rocking from side to side when the anchor 1 penetrates the sea floor, as well as the anchor 1 can be more firmly lodged. It also serves as a reinforcement of the outer wing portion 62.

In addition, in the present invention, the subsea subsurface insertion portion 80 installed on the front and rear of the shank 85 is also embedded in the seabed so that the anchor 1 is more firmly embedded in the seabed.

That is, as shown in Figure 4 (c) in the process of the anchor (1) to penetrate the seabed ground sub-sea sub-insertion portion 80 located on the top of the shank 10 in the drawing, but not embedded in the seabed ground, Auxiliary subsea ground insertion portion 80 located at the bottom of the 85 is embedded in the subsea ground with the subsea ground insertion portion 60 to secure the anchor (1). Of course, when the shank 85 is inclined in the opposite direction, the subsea sub-base insertion portion 80 in the opposite direction as described above is of course embedded in the seabed. In addition, the subsea basal insertion part 80 installed at the front and rear of the shank 85 is connected to the shank 85 by upper and lower connection strings 81 and 82, and then the subsea basal insertion part 80 If the) is open to each other, the upper and lower connecting straps 81, 82 is extended, the sub-sea sub-bed insertion portion 80 is stuck to the seabed as this operation is repeated.

In addition, the present invention is that the fixed shaft 53 is connected between the two frames 51 in order to prevent the shank 85 is further opened at a certain angle, the fixed shaft 53 is a shank 85 is If it does open, it supports not to open at any position.

Anchor (1) of the present invention as described above can be installed in a membrane penetration as well as continuously digging deep into the seabed to maximize the efficiency of the anchor (1) to improve the workability, and also anchors in the sand, gravel layer of the seabed (1) is easily embedded, which is good for stability and shortens working time, thereby reducing construction cost.

As described above, the anchor 1 of the present invention is excellent in workability and economical efficiency as well as safety and installation methods as described below.

That is, the function of the anchor 10 can be exhibited at 100% according to the tide direction at the time of tidal tide, and the two anchors 1 are operated simultaneously so that there is almost no movement by tidal tide.

More specifically, as illustrated in FIGS. 5 and 6, the above-described anchor 1 is connected to the seabed by the longitudinal main wire 6 and the horizontal main wire 7 in the shape of a crisscross. When the change is high or the difference between the tide is high, the main wires (6) (7) at the same time because the force is applied in all directions, and the movement of the anchor is almost eliminated as in the prior art and solves the problem of being pulled out severely. If the difference between the tide and the wave is severe, the vertical main wire 6 and the horizontal main wire 7 are connected to the cross as described above, and the vertical main wire 6 and the horizontal main wire 7 are vertical. The center wires 4 are connected to each other, and the subwires 5 connected to both sides of the lower end of the floating body 2 are connected to the longitudinal main wires 6 so that a plurality of such wires are simultaneously applied in all directions. As it works, the main wire goes up and down a little like a virtual ship, and there is no problem of losing it as in the prior art, which solves the problem of operating only one anchor whenever the tide changes, regardless of the direction of the tide. A plurality of anchors (1) to operate the force at the same time to double the efficiency of the anchor (1) so that there is almost no movement of the anti-vibration membrane by tidal tides.

In addition, the present invention supports the support rope (9) installed on one side or both sides of the bottom of the float (2) to support the float (2) and the anti-fouling film (3) as well as the support rope (9) and cross-sectional wire By the connection wire 8 connected to (7) it is possible to firmly protect the fouling prevention film (3).

As described in detail above, the present invention is equipped with a pointed submarine ground insertion part so that it can easily penetrate into the seabed, and in particular, by maximizing the efficiency of the anchor by applying the operation principle of the stockless anchor of the marine ship, fixing the offshore structure It is to achieve. And workability (dropping installation continuously penetrates into the seabed by the weight and function of the stockless anchor, maximizing the function of the anchor, simple to remove and maintain, and shorten the air) and stability (exact Maintain linearity of design position, minimize positional deviations as long as there is no membrane damage in any algae and waves, easy to sand and gravel layers on the seabed, and clearly fulfill the role of preventing pollution at sea) and economy (reduce construction cost by shortening working time) , Recyclable, and easy to install), and also improved the installation method (regardless of the direction of high and low tide, operating both anchors at the same time to double the anchor efficiency, so that the movement of the dustproof membrane by tidal tides is almost impossible.
