Description

[0001] The present invention relates to an artificial wall structure having a natural rock shape using an anchor,

The present invention relates to a natural rock-type artificial wall installation structure using an anchor, and in particular, it is easy to reinforce a slope, thereby shortening construction time and cost, forming a planting space by slope reinforcement, Natural rock-type artificial wall, which has a natural rock-shaped artificial wall and an anchor structure that is fixed at a right angle to the slope, And an artificial wall structure of a natural rock type using an anchor.

As the industry develops, it is inevitable to develop steep slopes such as mountains and mountains by constructing new complexes, constructing new cities, and constructing roads and railroads. Therefore, it has been demanded to establish the slope stabilization method that can satisfy the environmental conservation along with the construction and the economic efficiency while securing the stability of the road and the like by increasing the utilization of the land. As a result of these demands, researches on artificial wall making methods using nailing method and anchor have been actively carried out.

By fixing the artificial wall to the slope using nail or anchor, it is possible to prevent the landslide flowing down from the soil. In the anchor method, the slope is cut at a predetermined angle, the artificial wall is installed, the anchor is penetrated through the artificial wall and the slope by a predetermined distance, and the anchor is permanently grouted with mortar or the like in the ground, .

In the prior art, Patent Application No. 10-2003-012049 relates to a retaining wall structure using a permanent anchor and a precast concrete panel, and a method of constructing the retaining wall, which comprises horizontally arranging the ground along a boundary line to which the retaining wall is to be installed, A step of placing a panel on which hollows are formed on a horizontally arranged ground, placing a slope so as to be gradually inclined downward with respect to a horizontal direction of the earth pressure to be applied to the panel, A step of inserting an anchor into the insertion hole of the anchor and fixing the rear end of the anchor to the insertion hole of the inclined paper; a step of tilting the anchor; a step of fixing the tip of the tensioned anchor to the panel; And a method of constructing the retaining wall composed of the embankment step.

This patent application No. 10-2010-0089517 relates to a method of constructing a precast retaining wall panel and a precast retaining wall panel using the semi-prismatic back wall panel. The precast retaining wall panel includes a pre-casting member installed internally so that the anchor member is sloped downward, When the slab is constructed on the slope, the rear surface of the concrete is sandwiched by the semi-dry type backfill with the soil of the ground surface in a wedge shape to facilitate the installation of the precast retaining wall panel, The present invention provides a method of constructing the precast retaining wall panel using the precast retaining wall panel and the semi-dry type backcourt.

The problems of the above techniques are that there is a problem in that the durability of the artificial wall may be problematic because the amount of backfilling soil buried in the back surface of the artificial wall is large and the force applied to the artificial wall and the anchor supporting the artificial wall becomes large.

In addition, there is a problem that the artificial wall is vertically installed, and the tensile force of the anchor is weakened due to the weight of the artificial wall.

Also, since the amount of backfill soil filled in the rear surface of the artificial wall is large, the construction period is lengthened and the construction cost is increased.

Disclosure of the Invention The present invention has been conceived to solve the problems as described above, and it is an object of the present invention to minimize the amount of backfill soil filled in the rear surface of the artificial wall and to reduce the tensile force of the anchor due to its own weight, The present invention provides a natural rock-type artificial wall installation structure using an anchor capable of forming an artificial wall.

In order to achieve the above object, the present invention provides a structure for installing a natural rock-type artificial wall using an anchor including a natural rock-type artificial wall installed for slope stability and an anchor for fixing the artificial wall, A stepped slope part composed of a flat surface formed by cutting and arranging the ground at a predetermined angle, a slope surface, and a perforation in which an anchor is inserted; Supporting concrete installed on the flat surface; An anchor hole formed on the upper surface of the support concrete and installed to maintain a predetermined distance from the inclined surface, an anchor hole formed at a position corresponding to the perforation, an anchor groove having an anchor end located in front of the anchor hole, A natural rock-type artificial wall formed by a cap for covering an anchor groove; An inclined grooved layer formed by filling mortar or cement paste in a space between the artificial wall and the inclined surface; An anchor that penetrates the anchor hole and the ground portion and is seated on the perforation formed perpendicularly to the inclined surface; And an anchor grouting layer which is filled with mortar or cement paste into the anchor hole of the artificial wall and the perforation where the anchor is seated, wherein the anchor includes a head pipe positioned at an inner center, A grip fixing plate for fixing the pressing grip at the rear of the pressing grip; an epoxy filled outside of the pressing grip; and a fixing unit for fixing the pressing grip on the outer peripheral surface of the epoxy An outer cap which surrounds the outer circumferential surface of the inner cap and through which the head pipe passes forward; and a cap fixing plate which fixes the inner cap, the outer cap and the grip fixing plate from the rear, And a front end pipe connected to the head pipe and having a grouting hole formed therein; A grouting pipe connected to a rear end of the head pipe; A plurality of steel wires fixed to the gripping grips; At least one stopper provided at a rear end of the distal end head to prevent retraction of the distal end head; A pressure plate inserted and fixed in the anchor groove; And a reinforcement head located in the anchor groove and for reinforcement and reinforcement of the rear end of the steel wire supported by the support plate. The present invention also provides a structure for installing a natural rock-type artificial wall using the anchor.

In the present invention, at least one drain pipe may be installed at a predetermined position of the artificial wall to extend into the ground of the slope portion. By installing more than one drainage pipe on the artificial wall, it is possible to prevent the occurrence of grounding, which can occur due to penetration of moisture such as rainwater into the ground.

In the present invention, an upper portion of the artificial wall is formed with an extension portion that extends further in the vertical direction with respect to the flat surface, and the space between the extension portion and the inclined surface can be filled with backfill soil. The artificial wall may be spaced a predetermined distance from the inclined surface, and an upper portion of the artificial wall may be further extended in the vertical direction with respect to the flat surface. It is grouted with mortar between the backside of the artificial wall and the slope, and the backfilling soil can be used as a planting space such as a tree or a flower in the space between the extension part and the slope. In addition, since the space between the extension portion and the inclined surface is not wide, a large amount of gravel is not required, so that the construction period is shortened and the construction cost is reduced.

In the present invention, an anchor groove in which the anchor end is located and a cap for covering the anchor groove may be further formed in front of the anchor hole. Since the end of the anchor is covered with the cap, it is not exposed to outside air such as aesthetics or rainwater, and therefore, it can have an advantageous effect on maintenance. According to the present invention, there is provided an anchor comprising: a front end head; a plurality of steel wires fixed to the front end head; a latching pipe provided at a rear end of the front end head to interfere with retraction of the front end head; And a reinforcement head located in the anchor groove and for reinforcement and reinforcement of the rear end of the steel wire supported by the support plate. By providing a latching pipe at the rear end of the leading end head, the latching pipe interferes with the retraction of the leading end head, so that a strong tensile force can be generated. The stopping pipe may include an insert portion formed at one end, an insert portion having a diameter capable of being seated in a seat portion formed at the other end, a plurality of stoppers formed on the outer circumferential surface of the pipe, and a rake fixed to the stopper have. The rake is formed at an obtuse angle so that it can be easily inserted in the direction of travel. When a pulling force is applied to the leading end head by pulling the leading end head, the rake is arranged at an acute angle with respect to the traveling direction. Therefore, a strong tensile force can be given to the head end.

Since the backfill soil is filled only in the space between the extension part of the artificial wall and the sloped surface, the amount of the earthfill to be filled can be minimized, and the construction period and cost can be shortened.

Also, the artificial wall is installed at the same slope as the slope, and grooves are formed in the space between the artificial wall and the slope by mortar to fix the slope and the artificial wall to each other. It is possible to maximize the tensile force of the anchor without reducing the tensile strength of the anchor generated when the sagging is performed along the inclined surface.

Further, by fixing the front end head of the anchor using the latching pipe, the tensile force of the anchor is increased.

In addition, semi-permanent artificial wall construction is possible by not exposing the ends of the anchors to the outside air, and it is also possible to maximize the tensile force by reinspection by installing a reinforcement head.

In addition, since the amount of soil to be cut can be minimized without cutting a large amount of the gravel, it is economical and the construction is fast.
