1 to 5 , in the anchor module 10 according to an embodiment of the present invention, one end of the tension member T is inserted into the ground and the other end is exposed to the ground, so that the tensile force of the tension member T is applied. It may be a device for stabilizing the ground by

As an example, the anchor module 10 may include an inner body (not shown) that is inserted into the ground to accommodate one end of the tension member T, and a wedge part 100 that restrains the other end of the tension member T. ) may be further included.

For example, the wedge part 100 may be in contact with the tension member T to constrain the tension member T, and may be formed in plurality.

For example, the wedge part 100 may include a wedge restraining part 120 surrounding the tension member T and constraining the tension member T.

For example, the wedge restraining part 120 may form a concave-convex surface that increases the wedge action to increase the restraint of the tension member T.

For example, the anchor module 10 may further include a fixing unit 200 forming a through hole S2 through which the tension member T passes and an insertion hole S1 into which the wedge unit 100 is inserted. can

As an example, the fixing unit 200 may be disposed on the upper side of the acupressure plate (not shown) seated on the ground, and the tensile force from the tension member T is transmitted through the wedge part 100 and delivered to the acupressure plate. can

As the acupressure plate compresses the ground, the ground may be stabilized.

For example, the tension member T may be inserted into the ground through the through hole S2 and the insertion hole S1 , and the wedge part 100 may be inserted into the insertion hole S1 . have.

The insertion hole S1 may form a space having a shape corresponding to the shape of the wedge part 100 .

For example, the wedge part 100 and the insertion hole S1 may have an upper-gwang-lower narrow shape that becomes narrower toward the lower side.

For example, when the wedge part 100 is inserted into the insertion hole S1 and receives an external force in a downward direction, it may be pressed to the fixing part 200 to constrain the tension member T.

In order to re-tension or remove the tension member T, an operator may lift the tension member T exposed in the state of FIG. 3 in an upward direction.

At this time, between the wedge part 100 and the fixing part 200, it may be in an adsorption state in which it is difficult to separate due to the tensile force of the tension member T.

In this adsorption state, the wedge part 100 and the fixing part 200 are pressed against each other due to the occurrence of corrosion on the contact surface, and a state in which mutual separation is difficult may be reached.

In order to solve this problem, as shown in FIGS. 1 to 3 , the wedge part 100 faces the wedge body part 110 and the fixing part 200 forming the insertion hole S1. It may be provided with a wedge concave-convex surface 130 formed thereon.

The wedge body part 110 may mean a matrix for restraining the tension member T, and the wedge concave-convex surface 130 is on the fixing part 200 among the surfaces constituting the wedge body part 110 . It may mean an uneven surface formed on the opposite surface.

The Wetchi concavo-convex surface 130 may mean a surface having concavities and convexities such as a screw thread through a milling device, rather than a plane.

However, the unevenness of the wedge concave-convex surface 130 is not limited to being formed by a milling device, and may be formed by various methods such as etching, injection, etc. from the standpoint of a person skilled in the art.

As a result, the acid of the wedge concave-convex surface 130 may be in contact with the anchoring unit 200 , but the valleys may be spaced apart from the anchoring unit 200 , so that the area in contact with the anchoring unit 200 is small. can get

Furthermore, it is possible to minimize corrosion by allowing external air to flow in and out through the space spaced apart between the troughs of the wedge concavo-convex surface 130 and the fixing unit 200 to evaporate water, which increases corrosion.

Here, as an example, the fixing unit 200 may include the fixing body 210 and the fixing uneven surface 220 formed on the surface forming the insertion hole S1.

For example, the fixing body part 210 may refer to a body for restraining the wedge part 100 , and the fixing uneven surface 220 is the wedge part among the surfaces forming the fixing body part 210 . It may mean a surface opposite to (100), that is, an uneven surface formed on the surface forming the insertion hole (S1).

The fixing uneven surface 220 may mean a surface having unevenness such as a screw thread through a milling device, not a flat surface.

However, the unevenness of the fixing uneven surface 220 is not limited to being formed by a milling device, and may be formed by various methods such as etching, injection, etc. from the standpoint of a person skilled in the art.

That is, the distance L1 between the wetchi concavo-convex surface 130 and the fixing uneven surface 220 at any point is the distance L1 between the wedge uneven surface 130 and the fixing uneven surface 220 at another arbitrary point. The distance L2 may be formed differently.

As a result, the acid of the wedge-shaped uneven surface 130 may be in contact with the acid of the anchoring uneven surface 220 , but the valley of the wedge-shaped uneven surface 130 is the mountain and/or the valley of the anchoring uneven surface 220 . may be spaced apart from, and the contact area between the Wetchi concavo-convex surface 130 and the fixing concavo-convex surface 220 may be reduced.

In addition, due to the uneven shape of the concave-convex surface 130 and the concavo-convex shape of the fixing uneven surface 220, the wedge 100 can be more firmly fixed to the fixing unit 200 by a wedge action, and furthermore, the Corrosion can be minimized by allowing external air to flow in and out through the space spaced apart between the wetchi concavo-convex surface 130 and the fixing concave-convex surface 220 so that water, which increases corrosion, is evaporated.

Hereinafter, an additional embodiment of the anchor module 10 will be described in more detail with reference to FIGS. 4 and 5 .

As an example, the wedge part 100 is disposed on the wedge uneven surface 130 and further includes a wedge cover part 140 that prevents direct contact between the wedge uneven surface 130 and the fixing uneven surface 220 . can be provided

For example, the wedge cover part 140 may be configured to cover the wedge concavo-convex surface 130 opposite to the fixing part 200 forming the insertion hole S1 .

The wedge cover part 140 may cover the wedge concavo-convex surface 130 to prevent the wedge body part 110 and the wedge concavo-convex surface 130 from being corroded.

In addition, in that the wedge cover part 140 is disposed on the wedge concavo-convex surface 130 , the wedge cover part 140 is more firmly formed by the unevenness of the wedge uneven surface 130 . ) can be placed on

Furthermore, as an example, the wedge cover part 140 may form a cover concave-convex surface (A) on a surface opposite to the fixing part 200 .

The cover concavo-convex surface (A) may mean a surface having concavities and convexities such as a screw thread through a milling device, rather than a flat surface.

However, the concavo-convex of the cover concavo-convex surface (A) is not limited to being formed by a milling device, and may be formed by various methods such as etching, injection, etc.

As a result, the acid of the cover concavo-convex surface (A) may be in contact with the fixing unit 200 , but the valleys may be spaced apart from the fixing unit 200 , so that the area in contact with the fixing unit 200 is small. can get

Furthermore, it is possible to minimize corrosion by allowing external air to flow in and out through the space spaced apart between the trough of the cover concavo-convex surface (A) and the fixing unit 200 to evaporate water that increases corrosion.

Here, further, as an example, the wedge cover part 140 may have a different ionization tendency from the wedge body part 110 .

For example, when the ionization tendency of the wedge cover part 140 is greater than that of the wedge body part 110 , the corrosion of the wedge cover part 140 proceeds first to prevent corrosion of the wedge body part 110 . can do.

On the other hand, when the ionization tendency of the wedge cover part 140 is smaller than that of the wedge body part 110, the corrosion of the wedge cover part 140 does not progress relatively, so that the wedge body part 110 is corroded. It can be protected from the external environment.

Preferably, it is advantageous that the ionization tendency of the wedge cover part 140 is smaller than that of the wedge body part 110 , and as a result, corrosion of the wedge cover part 140 can be relatively limited.

For example, the wedge body part 110 may be made of a material containing iron as a major component, and the wedge cover part 140 may be made of nickel, lead, copper, or silver having a smaller ionization tendency than iron.

In addition, the wedge cover part 140 may be made of rubber, synthetic resin, or the like.

The wedge cover part 140 covers at least a portion of the upper surface of the wedge body part 110 as well as the wedge concave-convex surface 130 so that water flows between the wedge uneven surface 130 and the wedge cover part 140 . ingress can be prevented.

That is, the wedge cover part 140 covers the wedge concave-convex surface 130 and extends to continuously cover at least a portion of the top surface of the wedge body part 110 adjacent to the wedge uneven surface 130 . have.

Here, as an example, the fixing part 200 is disposed on the fixing uneven surface 220 and the fixing cover part 230 for preventing contact between the wedge cover part 140 and the fixing uneven surface 220 is formed. more can be provided.

For example, the wedge cover part 140 may be in direct contact with the fixing cover part 230 rather than in contact with the fixing uneven surface 220 .

In that the fixing cover part 230 is disposed on the fixing uneven surface 220 , the fixing cover part 230 is more firmly on the fixing uneven surface 220 by the unevenness of the fixing uneven surface 220 . can be placed in

For example, the fixing cover unit 230 may be a flat surface (B) having no irregularities.

Here, the fixing cover part 230 may cover the fixing uneven surface 220 and the fixing body part 210 and be connected to the fixing body part 210 to be integrated with the fixing body part 210 . In addition, it is possible to prevent the fixing uneven surface 220 and the fixing body 210 from being corroded.

For example, the fixing body part 210 may be made of a material containing iron as a main component, and the fixing cover part 230 may be made of nickel, lead, copper, or silver having a smaller ionization tendency than iron.

In addition, the fixing cover part 230 may be made of rubber, synthetic resin, or the like.

Here, as an example, the fixing cover part 230 may have a lower strength than the wedge cover part 140 .

As a result, when the wedge cover part 140 receives an external force in the downward direction while in contact with the fixing cover part 230, the wedge cover part 140 having an uneven surface is the fixing cover part 230. By pressing the surface (B) of the wedge action can be firmly fixed on the fixing cover portion (230).

Furthermore, external air flows in and out through the space spaced apart between the valley of the uneven surface of the wedge cover part 140 and the fixing cover part 230, so that water that increases corrosion can be evaporated, thereby minimizing corrosion can do.

Here, as an example, the fixing cover part 230 may cover at least a portion of the fixing uneven surface 220 and an upper surface of the fixing body part 210 .

The fixing cover part 230 covers at least a portion of the upper surface of the fixing body part 210 as well as the fixing uneven surface 220 so that water flows between the fixing uneven surface 220 and the fixing cover part 230 . ingress can be prevented.

That is, the fixing cover part 230 covers the fixing uneven surface 220, but extends to continuously cover at least a part of the upper surface of the fixing body part 210 adjacent to the fixing uneven surface 220. have.

In the above, the configuration and features of the present invention have been described based on the embodiments according to the present invention, but the present invention is not limited thereto, and it is understood that various changes or modifications can be made within the spirit and scope of the present invention.
