FIG.

1 to 7, the perforation hole sealing apparatus 10 according to an embodiment of the present invention includes a perforation hole formed in the ground, a reinforcement material inserted into the perforation hole, and grouting is injected into the perforation hole, The filling material is inserted into the perforation hole so as to prevent the reinforcing material and the grouting from falling out of the perforation hole in the stabilizing operation, (100) for providing an insertion space (S1) into which the stiffener can be inserted and inserted into the perforation hole, the main body part (100) being adapted to be cured in the perforation hole, A grip portion 200 spaced from the main body 100 by a predetermined distance L and an external force applied to the main body 100 by the external force It may include 300.

The perforated hole sealing apparatus 10 according to an embodiment of the present invention further includes a connecting portion 400 for allowing the grip portion 200 to be spaced apart from the main body 100 by a predetermined distance L .

Here, the filler may be divided into a main body and a hardening agent, and the main body and the hardening agent may be separately packaged by the wrapping paper so as to be separated from each other and disposed in the perforation hole sealing apparatus 10.

For example, the wrapper may be a material that can be easily cut by an external force, or may be provided with a cut portion B that can be easily cut when an external force is partially applied.

An incision may mean tearing or splitting by an external force, but may also be a concept that may include being pushed by an external force to form a hole or burst.

When the subject and the curing agent flow out from the packaging paper and are mixed with each other, the filling material is expanded in volume and hardened to seal the perforation hole.

In addition, the faster the mixing speed of the subject and the curing agent is, the more the curing of the filler can be promoted.

The reinforcing member may be inserted into the perforation hole to reinforce the ground.

For example, the reinforcement may refer to a rock bolt, a soil nail, an anchor, or the like.

The main body 100 forms an insertion space S1 into which the reinforcing material can be inserted and the reinforcing material can be inserted into the perforation hole through the body portion 100 through the insertion space S1. have.

For example, the body portion 100 may be a cylindrical shape having a hollow shape, but is not limited thereto. The shape of the body portion 100 can be inserted into the perforation hole forming the insertion space S1, It is obvious that it can be transformed into.

For example, although not shown in the drawing, the main body 100 may be provided with recesses and protrusions on its outer surface so as to be fixed to the ground that defines the perforation hole.

For example, the concave-convex portion may be an elastic material.

The grip portion 200 may be spaced a predetermined distance from the main body 100 and may be positioned in the perforation hole.

Therefore, the spacing space may be formed between the grip unit 200 and the main body 100. [

The spacing space may be an area between the grip unit 200 and the main body 100.

For example, the gripper 200 can provide an area that the operator can grasp.

For example, the grip portion 200 may form an insertion space S2 into which the reinforcing member can be inserted.

The stiffener may be disposed in the perforation hole through the grip portion 200 and the main body 100.

For example, the grip portion 200 may be a cylindrical shape having a hollow.

The external force applying unit 300 may be moved with respect to the main body 100 by an external force.

The external force may be generated by an operator, or may be generated by a machine.

Here, any one of the main body 100 and the external force application part 300 may provide the arrangement space S4 in which the filler sealed in the packaging paper is disposed.

The arrangement space S4 may mean an area where the filler can be disposed.

For example, the main body 100 may form the arrangement space S4 so that the wrapping paper may be disposed on the main body 100, or the external force application unit 300 may be disposed in the arrangement space S4. And the wrapping paper may be disposed on the external force application unit 300. [

Here, the other one of the main body 100 and the external force application part 300 is configured to press the wrapping paper placed in the arrangement space S4 by the movement of the external force application part 300, (120).

The pressing portion 120 can be formed in various forms in the viewpoint of a person skilled in the art, provided that the pressing portion 120 presses the packaging paper to cut the packaging paper.

For example, the main body 100 may include the pressing portion 120, or the external force applying portion 300 may include the pressing portion 120.

That is, for example, when the main body 100 forms the arrangement space S4, the external force applying unit 300 may include the pressing unit 120. [

Conversely, for example, when the body portion 100 includes the pressing portion 120, the external force application portion 300 may form the arrangement space S4.

Hereinafter, for convenience of explanation, the main body 100 includes the pressing portion 120, and the external force applying portion 300 forms the arrangement space S4 in which the wrapping paper can be disposed .

For example, the main body 100 includes a case 110 defining a boundary between the insertion space S1 into which the reinforcing material can be inserted and a ground on the perforation hole, and a case 110, And the pressing part 120 protruding toward the arrangement space S4 of the external force application part 300. [

Here, the external force applying unit 300 may be moved in the spaced space by an external force.

The wrapping paper placed in the arrangement space S4 can be moved toward the pressing portion 120 by the positional movement of the external force applying portion 300 and can be cut by the pressing of the pressing portion 120 .

For example, the external force applying unit 300 may be configured such that the external force applying unit 300 reciprocally moves from the main body 100 toward the grip unit 200 and from the grip unit 200 toward the main body 100, Can be moved.

For example, when the external force applying unit 300 is moved from the grip unit 200 toward the main body 100 and is moved toward the pressing unit 120, The wrapping paper disposed in the pressurizing portion S4 may be pressed by the pressing portion 120 to be cut.

The filler discharged from the incised wrapping paper can be hardened on the perforation hole.

Here, when the external force applying unit 300 is moved from the main body 100 to the grip unit 200 by an external force, the pressing unit 120 moves the filler in the arrangement space S4 .

When reciprocating the movement of the external force application part 300, the filler can be further flowed, and as a result, can be hardened more quickly.

Here, as shown in FIG. 6, for example, the main body 100 may define a limit of the movement of the external force application unit 300.

For example, when the external force applying unit 300 is continuously moved from the grip unit 200 toward the main body 100, the external force applying unit 300 contacts the one end of the main body 100 It may no longer be moved in the same direction.

In addition, for example, the gripper 200 may limit the movement of the external force application unit 300.

For example, when the external force application unit 300 is continuously moved from the main body 100 toward the grip unit 200, the external force application unit 300 contacts one end of the grip unit 200 It may no longer be moved in the same direction.

The connection unit 400 may connect the grip unit 200 and the main body 100 so as to be spaced apart from each other.

The distance L between the grip unit 200 and the main body 100 can be determined by the length of the connection unit 400. [

For example, one end of the connection part 400 may be connected to the main body 100, and the other end may be connected to the grip part 200.

For example, the connection unit 400 may be integrally extended from the case 110 of the main body 100 or may be detachably connected to the case 110.

For example, the connection unit 400 may be integrally extended from the grip unit 200 or may be detachably connected to the grip unit 200.

For example, the grip unit 200 may include a groove K1 to which the connection unit 400 can be connected.

For example, the main body 100 and the grip unit 200 may not be moved by the connection unit 400.

For example, the connection unit 400 may guide the movement of the external force applying unit 300.

For example, the external force application unit 300 may include a sliding unit 330 that can be slid on the connection unit 400 to guide the movement of the external force application unit 300 by the connection unit 400.

Because of the mutual interference between the sliding part 330 and the connection part 400, the external force application part 300 can be moved in a predetermined direction without being separated from the spacing space.

In one example, the arrangement space S4 providing an area in which the wrapping paper can be disposed can be defined by the space forming part 320 surrounding at least a part of the wrapping paper.

The space forming part 320 may be formed in the external force application part 300.

For example, the external force applying unit 300 may include a head 310 providing an area to which an external force can be applied, a space forming unit 320 extending from the head 310 toward the pressing unit 120, And the sliding part 330 extending from the head part 310 toward the main body part 100.

Also, the external force applying unit 300 may form an insertion space S3 into which the reinforcing member can be inserted.

The space forming part 320 and the sliding part 330 may be integrally formed from the head part 310 or may be detachably coupled to the head part 310.

For example, the wrapper may be disposed on the arrangement space S4 formed by the space forming portion 320. [

Accordingly, as the external force applying unit 300 moves relative to the main body 100 and the grip unit 200, the external force applying unit 300 applies the external force to the main body 100 and the grip unit 200, And can be moved with respect to the gripper 200 as a reference.

FIG. 8 is a schematic perspective view illustrating a pressing unit according to an embodiment of the present invention, and FIG. 9 is a schematic perspective view illustrating a space forming unit according to an embodiment of the present invention.

As shown in FIG. 9, for example, the space forming portion 320 may include a cut-out portion B formed by partially cutting.

The filler flowing out of the wrapping paper can be discharged from the space forming part 320 through the cutout part B.

8, the pressing portion 120 may include a tip portion 121 for pressing the wrapping paper and a flow guide portion 123 for guiding the flow of the filler flowing out from the wrapping paper .

For example, the tip portion 121 may reach the wrapping paper first.

As the tip portion 121 presses the wrapping paper, the wrapping paper can be cut.

The filling material flowing out from the wrapping paper due to the incision of the wrapping paper can be flowed by the flow inducing part 123.

When the wrapping paper is continuously moved to the pressing portion 120 by the movement of the external force application portion 300, the flow inducing portion 123 occupies the arrangement space S4, So that the filler located on the substrate can flow.

For example, the space forming part 320 and the pressing part 120 may guide the movement of the external force applying part 300.

For example, the space forming portion 320 and the pressing portion 120 may have a shape corresponding to each other, and the pressing portion 120 may be inserted into the space forming portion 320.

For example, when the pressing portion 120 is inserted into the space forming portion 320, the space forming portion 320 and the pressing portion 120 may guide the external force applying portion 300 to prevent rotation have.
