{ANCHOR FOR OFFSHORE STRUCTURES}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a civil engineering field, and more particularly, to a submersible submarine fixing structure.

As the problem of the noise caused by the wind power generation structure of the land is pointed out, an attempt is made to construct and use the wind power generation structure at sea.

If the water depth is shallow, it is necessary to form a foundation on the sea floor and install the wind power generation structure thereon. However, if the water depth is deep, it is difficult to perform the foundation work of the sea floor.

1, a wire 20 is connected to a wind power generation structure composed of a tower 11, a propeller 12, and a float 13, and a lower end of the wire 20 is connected to a bottom surface Use a floating foundation that secures to an undersea fixed structure (anchor: 21).

However, in the case of the conventional method, there is still a problem that such an undersea fixing structure is required to be installed on a deep sea floor.

SUMMARY OF THE INVENTION The present invention has been made to overcome the above-mentioned problems, and it is an object of the present invention to provide a submerged submerged anchoring structure having excellent workability and excellent structural stability.

In order to solve the above-described problems, the present invention provides a water treatment apparatus comprising: a body (110) formed of a material that sinks in water; (120) formed on the front of the main body (110) so that the main body (110) is conducted in a specific direction when the bottom surface is reached by sinking; An air chamber 130 formed in the main body 110 to apply buoyancy to adjust the sinking speed; And an inflow portion 131 and an outflow portion 132 formed in the main body 110 so as to communicate with the air chamber 130. The submerged submerged anchoring structure 100 shown in FIG.

The attachment 120 may include a flat portion 121 extending from the upper surface of the main body 110 to a flat surface; And an inclined portion 122 formed to be inclined downward from an end of the flat portion 121 and formed to meet a bottom surface of the main body 110.

The air chamber 130 may have a rear end higher than the front end so that the main body 110 sinks in an inclined manner.

The air chamber 130 may have a higher structure than the other side so that the main body 110 sinks in an inclined manner.

The air chamber 130 may have a structure in which the front end faces one side and the rear end faces the other side so that the main body 110 sinks in an inclined manner.

And a wedge portion 140 protruding downward from the bottom surface of the main body 110 so as to be submerged on the bottom surface due to the weight of the main body 110 when the submerged surface is reached by sinking.

It is preferable that the wedge part 140 is installed along the left and right direction with a length longer than the width.

Preferably, the wedge portions 140 are installed at a plurality of intervals.

The wedge part 140 is preferably inclined downward toward the rear.

It is preferable that the wedge part 140 has a structure in which the other side is directed forward and the other is directed backward.

The wedge part 140 is preferably formed by a sheet pile.

It is preferable that a hook 150 for coupling with the wire 20 is installed on the upper surface of the main body 110.

The present invention provides a submerged submerged anchoring structure having excellent workability and excellent structural stability.

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

As shown in FIG. 2 and subsequent drawings, the sinking submarine fixing structure 100 according to the present invention basically comprises a main body 110 formed by a material (concrete or the like) sinking in water; (120) formed in front of the body (110) so that when the bottom surface is reached by sinking, the body (110) is conducted in a specific direction; An air chamber 130 formed inside the main body 110 to apply buoyancy to adjust the sinking speed; And an inflow portion 131 and an outflow portion 132 formed in the main body 110 so as to communicate with the air chamber 130.

2 to 4, the direction in which the attachment 120 is formed is forward (Figs. 2 and 3), and the direction in which the flat portion 121 is formed is the upper side (Fig. 3).

Since the submarine fixing structure 100 is prevented from being damaged due to collision with the seabed surface since the sinking speed is adjusted to be slow due to the air in the air chamber 130, So that the seabed fixing structure 100 can be installed in a desired position and structure after sinking (Figs. 6 to 8).

The attachment 120 is a structure for allowing the main body 110 to conduct in a specific direction, and includes a flat portion 121 formed to extend from the upper surface of the main body 110 to be flat; And the inclined portion 122 formed so as to be inclined downward from the end of the flat portion 121 and to meet the bottom of the main body 110. In this case, (Figs. 2 and 3).

In order to allow the main body 110 to be turned in a specific direction, it is preferable that the main body 110 sinks with the upper attachment 120 in an inclined manner. For this purpose, the air chamber 130 formed in a rectangular cross- It is preferable to form it with a high structure (Figs. 2, 3, and 6).

For the above reason, it is preferable that the air chamber 130 is formed so as to be higher in the other side than the one side so as to sink the main body 110 in an inclined manner (FIGS.

Also, for the above reasons, it is preferable that the air chamber 130 is formed so that the front end thereof faces one side and the rear end faces the other side so as to sink the main body 110 in an inclined manner (Figs.

And a wedge portion 140 protruding downward from the bottom surface of the main body 110 so as to be buried on the bottom surface due to the weight of the main body 110 when the bottom surface is reached by sinking, The effect that the fixing structure 100 is more firmly fixed to the sea floor is added.

It is preferable that the wedge part 140 is provided along the left and right direction with a structure having a length longer than the width, in order to maximize the effect.

In the case where a plurality of the wedge portions 140 are provided so as to be spaced apart from each other, a more rigid structure can be obtained.

In order to effectively resist a load applied to the seabed fixing structure 100 by sinking in a specific direction, it is preferable that the wedge portion 140 is provided so as to be inclined downwardly toward the rear (FIG. 9).

In the above embodiment, the structure in which the air chamber 130 is formed so as to be inclined so that the seabed fixing structure 100 sinks in an inclined state has been described. In this state, when the sunken portion 140 sinks stably, It is preferable that the wedge portion 140 is formed in an inclined structure with one side of the wedge portion facing forward and the other of the wedge portion 140 facing backward (FIG. 4).

The wedge portion 140 can be realized by a plate-like structure or the like, and when it is formed by a sheet file, a more stable structural stability can be obtained.

If a hook 150 for coupling with the wire 20 is provided on the upper surface of the main body 110, it can be stably used for a structure of coupling the wind power generation structure to the wire 20 by the floating base.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It is to be understood that both the technical idea and the technical spirit of the invention are included in the scope of the present invention.
