Description

{METHOD FOR REINFORCING WALL PANEL USING NATURAL ROCK}

The present specification relates to a method for reinforcing a retaining wall, and more particularly, to a method for reinforcing a retaining wall using natural stone.

Unless otherwise indicated herein, the matters described in this identifier are not prior art to the claims of this application, and their description in this identifier is not intended to be an admission that they are prior art.

In general, a structure that prevents the collapse of soil is called a retaining wall, and the construction of a retaining wall is divided into a cut retaining wall installed on the cut surface by cutting the soil, and a fill retaining wall installed on the fill area.

There is a method of reinforcing existing retaining walls using the nail method, but there are problems such as a decrease in strength due to thermal deformation of the base material at the welding area, a delay in the process due to the rust prevention work process at the welding area, and a delay in the process due to the work of cutting the connecting reinforcing bars because the length change of the anchor and reinforcing bars is difficult.

In addition, there is a grid method among the methods of reinforcing retaining walls, but there are problems such as the impossibility of adjusting the spacing when connecting anchors and grid beams, and the delay in the process that occurs when measuring the length of each connecting bolt and cutting and joining them.

Therefore, it is necessary to develop a method that avoids processes that cause delays in the process, allows for anchor length adjustment, and allows reinforcement of retaining walls even by non-skilled workers by simply installing the finished product.

In this regard, Korean Patent Publication No. 10-1530871 discloses a natural stone retaining wall structure using a belt-shaped fiber reinforcement material and a construction method thereof, and Korean Patent Publication No. 10-1528725 discloses a slope reinforcement method using natural stone.

However, existing inventions do not disclose inventions that shorten the working time of reinforcement methods.

The present invention provides a method for reinforcing a retaining wall using natural stone, which is easy to work with and allows for adjustment of the length of a computerized bolt or anchor connecting natural stone and a slope through a nut combination.

In addition, it is obvious that the technical tasks are not limited to the technical tasks described above, and that other technical tasks may be derived from the following description.

According to one embodiment of the disclosed content, a method for reinforcing a retaining wall using natural stone includes a foundation construction step of constructing a foundation member on ground, a natural stone installation step of erecting a natural stone on top of the foundation member, a bolt fixing step of fixing an anchor bolt to the rear of the natural stone, a computer bolt connection step of connecting one end of the computer bolt to the foundation member, an anchor bolt connection step of connecting the other end of the computer bolt and the anchor bolt, and a soil filling step of filling soil to the rear of the natural stone.

In addition, the above-mentioned basic construction step can include pouring the basic and reinforced concrete, cutting the slope of the slope formed at the rear of the natural stone, inserting nail reinforcement bars, and injecting grout.

In addition, the above-mentioned foundation construction step can insert and connect a portion of the vertical bars extending upward and downward after pouring the foundation and reinforced concrete into the foundation and reinforced concrete.

In addition, the computer bolt connection step can connect a plate-shaped anchor plate with a nut to an end of the base member, and connect one end of the anchor plate and the computer bolt at a position adjacent to the base member.

In addition, the computer bolt connection step may insert an end of the base member into a hole formed in one end of a ring-shaped eye nut, and bolt one end of the computer bolt and the other end of the eye nut to each other.

In addition, the anchor bolt connection step can be performed by inserting the ends of the computer bolt and anchor bolt into each of the holes formed in the clip, and then fastening a nut to the ends of the computer bolt and anchor bolt.

In addition, between the bolt fixing step and the computer bolt connecting step, a clip having one end and the other end connected to the front and rear of the end of the anchor bolt and surrounding a predetermined space may be connected to the anchor bolt, and a grid connecting step of inserting a grid bar attached to the front of a mesh-shaped grid into the space may be further included.

In addition, construction can be repeated from the foundation construction stage to the soil filling stage on top of the soil.

According to one embodiment disclosed in the present specification, a method for reinforcing a retaining wall using natural stone has the advantage of improving the convenience of fastening and reducing the process time by allowing adjustment of the length between an anchor and a screw bolt to be connected to the natural stone.

In addition, the method of reinforcing a retaining wall using natural stones has the advantages of being able to stably fix natural stones using a grid according to the terrain, improving the convenience of connecting bolts using clips and anchor plates, and being able to control the tension of the grid.

Hereinafter, with reference to the attached drawings, the configuration, operation, and effect of a method for reinforcing a retaining wall using natural stone according to a preferred embodiment will be described. For reference, in the drawings below, each component is omitted or schematically illustrated for convenience and clarity, and the size of each component does not reflect the actual size. In addition, the same reference numerals refer to the same components throughout the specification, and drawing numerals for the same configuration in individual drawings are omitted.

As shown in Figures 1 and 2, the method (1) for reinforcing a retaining wall using natural stone includes a foundation construction step (S110), a natural stone installation step (S120), a bolt fixing step (S130), a computerized bolt connection step (S140), an anchor bolt connection step (S150), and a soil filling step (S160).

A method for reinforcing a retaining wall using natural stones (1) repeats the foundation construction stage (S110), natural stone installation stage (S120), bolt fixing stage (S130), computer bolt connection stage (S140), anchor bolt connection stage (S150), and soil filling stage (S160) after the soil filling stage (S160) when the height of the natural stones being manufactured increases, thereby reinforcing the vertically stacked natural stones (10, 11, 12) so that they are stably fixed in their current positions.

In the basic construction stage (S110), one end and the center of the nail reinforcement (100), which is a basic member, are inserted into a perforated inclined surface (50), and grout made of cement, mortar or any one of the chemicals is injected into the perforation to secure the nail reinforcement (100) to the ground forming the inclined surface (50).

In the basic construction stage (S110), another basic material, basic concrete (110), is poured on the lower part of a slope (50) made of soil or rock, and reinforced concrete (120) is poured on top of the basic concrete (110).

In the natural stone installation step (S120), before the reinforced concrete (120) hardens, a lower portion of the natural stone (10) is inserted into the reinforced concrete (120), and the remaining portion of the natural stone (10) extends upwards so as to be perpendicular to the ground.

In the bolt fixing step (S130), one end of the chemical anchor bolt (130) is inserted into a hole formed on the back surface of the natural stone (10) and fixed, and the other end of the chemical anchor bolt (130) is extended from one end to a position separated from the inclined surface (50) toward the rear by a predetermined distance.

In the computer bolt connection step (S140), one end of the computer bolt (140) penetrates the other end of the anchor plate (150) connected to the other end of the nail reinforcement bar (100), and is fixed to the anchor plate (150) by being connected to a nut placed at the rear of the anchor plate (150).

In the computer bolt connection step (S140), one end of the computer bolt (140) is connected to the nut by passing through a through hole (152) that passes through the anchor plate (150) at a position adjacent to the corner of the anchor plate (150).

In the computer bolt connection step (S140), the other end of the nail reinforcement (100) penetrates the hollow (151) of the anchor plate (150) formed in the shape of a square plate and is connected to a nut at the front of the anchor plate (150).

Therefore, in the computer bolt connection step (S140), the worker can conveniently adjust the connection position of the computer bolt (140) and the chemical anchor bolt (130) by changing the position of the anchor plate (150) and adjusting the position of the computer bolt (140).

In addition, in the computer bolt connection step (S140), the computer bolt (140) may be arranged so that the extension direction is horizontal to the ground or may be arranged so that it extends at an angle from one end toward the front and top, and even when the front of the anchor plate (150) is inclined toward the front and top, one end of the computer bolt (140) may pass through the through hole (152) and be arranged at the rear of the anchor plate (150).

That is, since the outer diameter of one end of the computer bolt (140) is smaller than the inner diameter of the through hole (152), one end of the computer bolt (140) can be connected to the anchor plate (150) after passing through the through hole (152) regardless of the position of the other end of the computer bolt (140), so the computer bolt (140) can be conveniently connected to the other end of the chemical anchor bolt (130) while changing the position of the other end of the computer bolt (140).

In addition, in the computer bolt connection step (S140), one end of each of the plurality of computer bolts (140) can be inserted into each of the through holes (152) and connected to the anchor plate (150), and the other end of each can be connected to the clip (160) by passing through the clip (160).

In the anchor bolt connection step (S150), the other end of the computer bolt (140) extends forward from one end by a predetermined distance and intersects with the chemical anchor bolt (130) at a position adjacent to the other end of the chemical anchor bolt (130) and is combined with the clip (160).

In the anchor bolt connection step (S150), the other end of the computer bolt (140) penetrates one side of a square plate-shaped clip (160) and is placed in front of the clip (160), and is combined with a nut to be combined with the clip (160).

In the anchor bolt connection step (S150), the other end of the computer bolt (140) intersects with the chemical anchor bolt (130) while moving to various positions with one end of the computer bolt (140) connected to the anchor plate (150) as an axis.

In the anchor bolt connection step (S150), the other end of the chemical anchor bolt (130) penetrates the other side of the clip (160) and is placed at the rear of the other side of the clip (160), and is fixed to the clip (160) by combining with a nut.

In the soil filling step (S160), soil (170) is filled on top of the reinforced concrete (120) between the natural stone (10) and the slope (50), and the soil (170) is filled and compacted to a horizontal line that is relatively lower than the upper surface of the natural stone (10).

After the soil (170) is filled to a horizontal line of a certain height, the natural stone installation step (S120), the bolt fixing step (S130), the computer bolt connection step (S140), the anchor bolt connection step (S150), and the soil filling step (S160) are repeated several times on top of the soil (170) to stack multiple natural stones (11, 12) and reinforce the retaining wall.

The method (2) for reinforcing a retaining wall using natural stone according to the present embodiment is substantially the same as the method for reinforcing a retaining wall using natural stone of FIGS. 1 to 3, except for the foundation bar (200), eye nuts (210, 220), chemical anchor bolts (132, 134, 136, 138), computer bolts (142, 144), grids (250, 260), natural stone installation step (S170), bolt fixing step (S180), and grid connection step (S190), and therefore the same reference numbers and names are used, and duplicate descriptions are omitted.

As shown in Figures 4 to 6, the method for reinforcing a retaining wall using natural stone (2) includes a foundation construction step (S110), a natural stone installation step (S120), a bolt fixing step (S130), a computerized bolt connection step (S140), an anchor bolt connection step (S150), a soil filling step (S160), a natural stone installation step (S170), a bolt fixing step (S180), and a grid connection step (S190).

A method for reinforcing a retaining wall using natural stones (2) can reinforce vertically stacked natural stones (10, 11, 12) so that they are stably fixed in their current positions by repeating the natural stone installation step (S120), the bolt fixing step (S130), the computer bolt connection step (S140), the anchor bolt connection step (S150), and the soil filling step (S160) instead of the natural stone installation step (S170), the bolt fixing step (S180), and the grid connection step (S190) after the soil filling step (S160) to increase the height of the retaining wall.

In the basic construction stage (S110), the foundation concrete (110), which is a foundation material, is poured at the front lower portion of the slope (50), and before the foundation concrete (110) hardens, one end of a foundation bar (200) that extends upward and downward in a cylindrical shape is inserted into the foundation concrete (110).

In the basic construction stage (S110), after the foundation concrete (110) has hardened, reinforced concrete (120) is poured on top of the foundation concrete (110) and the central portion of the foundation bar (200) is inserted into the reinforced concrete (120).

Reinforced concrete (120) can be poured on top of the foundation concrete (110) after the computer bolt connection step (S140) depending on whether eye nuts (210), computer bolts (142), and chemical anchor bolts (132) are installed.

In the basic construction stage (S110), the other end of the foundation bar (200) protrudes toward the upper part of the reinforced concrete (120) and can extend upward as the number of chemical anchor bolts (132, 134) connected to the natural stone (10) increases.

In the natural stone installation step (S120), the lower part of the natural stone (10) is inserted into the front inner side of the reinforced concrete (120) before the reinforced concrete (120) hardens, and the remaining part extends upwards so as to be perpendicular to the ground.

In the bolt fixing step (S130), one end of the chemical anchor bolt (132) is inserted into and fixed into a hole formed in the lower back surface of the natural stone (10), and the other end of the chemical anchor bolt (132) is extended from one end toward the rear and lower side by a predetermined distance.

In the bolt fixing step (S130), one end of the chemical anchor bolt (134) is inserted into and fixed in a hole formed on the back surface of the natural stone (10) at a position spaced from the upper portion of the chemical anchor bolt (132), and the other end of the chemical anchor bolt (134) is extended from one end toward the rear and bottom by a predetermined distance.

In the computer bolt connection step (S140), one end of the computer bolt (142) is connected to an eye nut (210) connected to a foundation bar (200), and in this case, the reinforcing concrete (120) is poured on top of the foundation concrete (110) while the eye nut (210) and the computer bolt (142) are connected to each other.

In the computer bolt connection step (S140), one end of each of the eye nuts (210, 220) is formed in a ring shape, and is lowered to surround the base bar (200) and connected to the base bar (200), and the other end of each of the eye nuts (210, 220) is bolt-connected with one end of each of the computer bolts (142, 144) by having a portion of one end protrude rearward in the shape of a nut.

In the computer bolt connection step (S140), one end of the computer bolt (144) is bolted to the other end of an eye nut (220) connected to the other end of the base bar (200), and the other end of the computer bolt (144) is arranged to extend forward and upward.

In the computer bolt connection step (S140), the inner diameter of the eye nut (210, 220) can be manufactured to be larger than the outer diameter of the base bar (200), and accordingly, the eye nut (210, 220) can be connected to the computer bolt (142, 144) with one end connected to the base bar (200) and the other end of the eye nut (210, 220) inclined toward the upper or lower front.

In the anchor bolt connection step (S150), one end of the computer bolt (142) is inserted into the reinforced concrete (120), and the other end of the computer bolt (142) partially intersects with the other end of the chemical anchor bolt (132), and the other end of the computer bolt (142) is connected to the chemical anchor bolt (132) through a clip (160).

In the anchor bolt connection step (S150), the other end of the computer bolt (142) is positioned at the front of the clip (160) by penetrating one side of the clip (160), and is fixed to the clip (160) by being combined with a nut, and the other end of the chemical anchor bolt (132) is positioned at the rear of the clip (160) by penetrating the other side of the clip (160) and is combined with a nut.

In the anchor bolt connection step (S150), the other end of the computer bolt (144) is partially intersected with the other end of the chemical anchor bolt (132), and the other end of the computer bolt (144) is connected to the chemical anchor bolt (134) through a clip (160).

In the anchor bolt connection step (S150), the other end of the computer bolt (144) is positioned in front of the clip (160) by penetrating one side of the clip (160), and is fixed to the clip (160) by being combined with a nut, and the other end of the chemical anchor bolt (134) is positioned in the rear of the clip (160) by penetrating the other side of the clip (160) and is combined with a nut.

In the soil filling step (S160), soil (170) is filled on top of the reinforced concrete (120) between the natural stone (10) and the slope (50), and the soil (170) is filled and compacted to a horizontal line that is relatively lower than the upper surface of the natural stone (10).

After the soil (170) is filled to a horizontal line of a certain height in the soil filling step (S160), the natural stone installation step (S120), bolt fixing step (S130), computer bolt connection step (S140), anchor bolt connection step (S150), and soil filling step (S160) corresponding to the method for reinforcing a retaining wall using natural stones (1) on top of the soil (170) are repeated several times to stack a plurality of natural stones (11, 12).

In the natural stone installation step (S170), the lower part of the natural stone (11) is installed on the upper front side of the soil (170) at the rear of the natural stone (10), and the remaining part of the natural stone (11) is extended upwards in the same direction as the extension of the natural stone (10).

In the bolt fixing step (S180), one end of the chemical anchor bolt (134) penetrates the lower part of the back surface of the natural stone (11) and is combined with the natural stone (11), and the other end extends toward the rear a predetermined distance.

In the bolt fixing step (S180), a plurality of chemical anchor bolts (134) can be attached at various locations while being spaced apart from each other on the upper and lower parts or left and right sides of the back surface of the natural stone (11) depending on the height or weight of the natural stone (11).

In the grid connection step (S190), the grid (250) is a reinforcing material formed in the form of a mesh-like grid structure, and a grid bar (251) extending toward one side or the other is formed in the front, and is connected to a chemical anchor bolt (136) through a clip (165).

In the grid connection step (S190), the grid (250) is placed in close contact with the upper surface of the soil (170) after filling the rear of the natural stone (11) with soil (170) and is connected to the chemical anchor bolt (136) through the clip (165).

In the grid connection step (S190), the grid bar (251) and a front portion of the grid (250) are placed below the chemical anchor bolt (136), and the grid bar (251) penetrates the clip (165) connected to the chemical anchor bolt (136) and is connected to the clip (165).

In the grid connection step (S190), one end of the clip (165) is connected to the front of the chemical anchor bolt (136), the central portion extends in a ring shape surrounding the grid connection space (166) formed at the rear and bottom from one end, and the other end extends upward from the central portion and is connected to the chemical anchor bolt (134).

In the grid connection step (S190), after the grid bar (251) is inserted into the grid connection space (166), the nut is connected to the other end of the chemical anchor bolt (136) and moved to the other end of the clip (165), and the clip (165) is moved forward by the nut, thereby moving the grid bar (251) forward.

In the grid connection step (S190), when the clip (165) is moved forward by the nut, the grid bar (251) pulls the grid (250), so the grid (250) is spread out, and the contact surface between the grid (250) and the upper surface of the soil (170) is improved.

In the grid connection step (S190), after the grid (250) is connected to the chemical anchor bolt (136) on top of the soil (170), soil (170) is additionally filled on top of the grid (250), and then the grid (260) is placed on top of the soil (170) and connected to the chemical anchor bolt (138).

Installing grids (250, 260) at the rear of natural stone (11) in the grid connection step (S190) is suitable for terrain where a plane (55) of a certain length is formed on the upper side of the slope (50) and a slope (57) is formed at the rear.

Meanwhile, the method for reinforcing a retaining wall using natural stone (2) can be performed by performing a bolt fixing step (S180) and a grid connection step (S190) after the foundation construction step (S110) and the natural stone installation step (S120) to place the grid (250) on top of the reinforcing concrete (120).

In addition, the method (2) for reinforcing a retaining wall using natural stone can be performed by going through a soil filling step (S160) while the grid (250) is placed on top of the reinforced concrete (120), and then going through a foundation construction step (S110), a natural stone installation step (S120), a bolt fixing step (S130), a computer bolt connection step (S140), an anchor bolt connection step (S150), a soil filling step (S160), a natural stone installation step (S170), a bolt fixing step (S180), and a grid connection step (S190) on top of the soil (170).

That is, the method for reinforcing a retaining wall using natural stones (2) can be constructed so that a foundation bar (200) and a grid (260) connected to a grid (250), a computer bolt (142) and a chemical anchor bolt (132) are arranged in order behind each of the natural stones (10, 11, 12), and various constructions can be performed by changing the arrangement of the foundation bar (200) and the grid (260) connected to the grid (250), the computer bolt (142) and the chemical anchor bolt (132).

In addition, the foundation concrete (110) and reinforced concrete (120) performed in the foundation construction stage (S110) can be constructed not only on the natural stone (10) but also behind the natural stone (11, 12), and depending on the terrain, only the chemical anchor bolt (136) and grid (250) can be constructed behind the natural stone (10, 11, 12) instead of the foundation bar (200), the computer bolt (142, 144) and the chemical anchor bolt (132, 134).

At this time, the construction stages of the method for reinforcing a retaining wall using natural stone (2) can be carried out in the following order: foundation construction stage (S110), natural stone installation stage (S120), bolt fixing stage (S180), grid connection stage (S190), and soil filling stage (S160).

As shown in Fig. 5, the natural stone (11) placed relatively higher is placed rearward at a position corresponding to the natural stones (10) placed lower, and is in close contact with the back surface of the natural stones (10), so there is an advantage in that the natural stone (11) placed higher is stably fixed by the natural stones (10) placed lower.

The grid bar (251) installed in front of the grid (250) is connected to the grid (250) through a cable tie, and the soil (170) filled in the space where the grids (250, 260) are placed firmly maintains the positions of the grids (250, 260).

Foundation concrete (110) and reinforced concrete (120) can be poured on top of the soil (170) that is filled in the location where the grids (250, 260) are placed. In this case, there is an advantage in that the grids (250, 260) are stably fixed by the weight of the foundation concrete (110) and reinforced concrete (120).

Meanwhile, a grid (250) is arranged at the rear of the natural stone (10) so that a foundation bar (200) can penetrate upward and be joined to the natural stone (10) through a chemical anchor bolt (136), and the other end of the foundation bar (200) can be joined to the natural stone (10) through a computerized bolt (144) and a chemical anchor bolt (134).

At this time, since the foundation bar (200) and the grid (250) are placed simultaneously, the grid (250) is stably fixed inside the soil (170) by restricting forward or backward movement by the foundation bar (200).

In addition, the nail reinforcement bar (100), the computer bolt (140), the anchor plate (150) and the chemical anchor bolt (130) of Fig. 1 can be placed at the rear of the natural stone (10) together with the foundation bar (200), the computer bolt (144) and the chemical anchor bolt (134), and additionally, a grid (250) and the chemical anchor bolt (136) can be placed.

Accordingly, the nail reinforcement (100), the foundation bar (200), and the grid (250) can be simultaneously placed at the rear of one of the natural stones (10, 11, 12) to stably fix the natural stone (10, 11, 12).
