Description

Technology Field

[0001] The present invention relates to a method for constructing a gabion retaining wall, and more specifically, to a method for constructing a gabion retaining wall in which an inclined block installed on an inclined surface is fixed to a grid-shaped fixing means to provide an anti-slip function, a drainage perforated pipe is embedded in a foundation stone to protect the drainage perforated pipe and prevent damage, and the inclined block is installed in a zigzag arrangement to distribute the load of the gabion retaining wall and ensure stability. Background Technology

[0002] Generally, gabions are structures made by filling baskets made of wire mesh or steel wire with stones or gravel. They are used in various fields such as retaining walls, fences, embankments, landslide and rockfall prevention, benches, and sculptures. They are eco-friendly because they use natural stones, and they give a charming and natural feel.

[0003] The above-mentioned gabion retaining wall is a gravity retaining wall constructed by combining wire mesh and natural stone. It is a structure that offers slope stability, drainage, aesthetics, and economic efficiency. However, compared to general concrete retaining wall construction, gabion retaining walls have the disadvantage of relatively high material costs. In particular, since the price of natural stone varies significantly depending on the type and size, it requires high construction costs. Additionally, because the entire surface is composed of natural stone, it may lack uniformity due to differences in color and size, and it has the disadvantage of requiring maintenance as soil and weeds grow in the gaps.

[0004] In addition, since the above gabion retaining wall is made of wire mesh, problems regarding corrosion may occur, and the rate of corrosion may be accelerated, especially in humid areas or near the seaside, and there is a possibility of damage to the wire mesh during construction.

[0005] However, as a prior art that deviates from wire mesh structures and constructs a box-structured retaining wall block to form a gabion retaining wall by stacking the retaining wall blocks, as described in Korean Registered Patent Publication No. 10-1775008, the retaining wall construction block comprises: a block body having an open upper surface and a lower surface and a space connecting the upper surface and the lower surface, and having one or more frames embedded and molded inside concrete; one or more drainage holes provided in at least a part of the block body; an upper cover provided to cover the upper side of the block body; a lower cover provided to cover the lower side of the block body; and one or more fastening parts provided on the outer side of the block body; wherein at least a part of the frame protrudes from the upper side of the block body, and one or more insertion holes are provided at a position corresponding to the protruding frame on the lower side of the block body.

[0006] When the gabion retaining wall of the above prior art is constructed on a slope such as an embankment or an excavation, moisture absorbed by the soil is not properly discharged, causing the blocks to shift due to soil loss, which can lead to displacement and collapse. In particular, when the weather gets cold, such as in winter, the moisture freezes and expands in volume, causing the gaps between the blocks to widen and the gabion retaining wall to collapse.

[0007] In addition, before constructing blocks on slopes such as embankments or cut slopes, a drainage pipe is installed at the bottom of the slope to drain water flowing under the gabion wall to the outside. However, there is a problem that the drainage pipe, made of PVC, is damaged during the installation process, and the drainage pipe is frequently damaged by the load of the gabion wall in the form where it is installed at the bottom of the constructed blocks. Furthermore, since the gabion wall cannot be reconstructed even if the drainage pipe installed in the gabion wall is damaged, there is a problem that the drainage pipe must be used in its damaged state.

[0008] The above gabion retaining wall has a problem of reduced stability because it is constructed in a grid shape on slopes such as embankments or cut slopes, where the blocks installed at the bottom receive a large load or the load is received in a single part. Prior art literature

[0009] (Patent Document 0001) KR 10-1775008 B1 2017.09.04. The problem to be solved

[0010] Accordingly, the inventors of the present invention have researched and developed the present invention to solve the problems of the gabion retaining wall mentioned above. The present invention aims to provide a method for constructing a gabion retaining wall that enables the blocks to be stably constructed on the slope of an embankment or cut slope, allows the blocks to be constructed in a fixed state without slipping on the slope, distributes the load so that a large load is not applied to the blocks installed at the bottom of the slope, prevents the drainage pipe from being damaged during installation, and protects the drainage pipe from being damaged by the load of the gabion retaining wall. means of solving the problem

[0011] As a means of solving the problem, the present invention comprises: a geotextile installation step of covering a slope with a geotextile and compacting the slope so that a geotextile can be installed on the slope; a foundation stone installation step of installing a foundation stone at the bottom of the slope so that a space can be formed between the lower slope formed at the bottom of the slope and the rear of the vertical block; a vertical block construction step of vertically constructing a vertical block above the foundation stone; a gravel filling step of laying gravel in the space to conform to the lower slope; a side block installation step of installing a side block on the filled gravel; and a slope block construction step of constructing a slope block on the upper slope of the side block and the slope.

[0012] As another means of solving the problem, the present invention includes a fixing means installation step in which a fixing means, such as a steel rod or an anchor, is installed perpendicularly to an inclined surface; and in the inclined surface block construction step, the inclined surface block constructed on the inclined surface is fixed to the inclined surface by the fixing means.

[0013] As a means of solving other problems, the present invention comprises: a geotextile installation step of covering the slope with a geotextile and compacting the slope so that the geotextile can be installed on the slope; a foundation stone installation step of installing a foundation stone at the bottom of the slope so that a space can be formed between the lower slope formed at the bottom of the slope and the rear of the vertical block; a vertical block construction step of vertically constructing a vertical block above the foundation stone; a gravel filling step of laying gravel to conform to the lower slope in the space; a side block installation step of installing a side block on the filled gravel; a fixing device installation step of assembling and installing a fixing device on the geotextile; and a slope block construction step in which the slope block is constructed on the right slope of the side block and the slope while being secured by a locking cut formed on the rear of the slope block to the fixing device installed on the geotextile.

[0014] As a means of solving other problems, the present invention comprises: a geotextile installation step of covering the slope with a geotextile and compacting the slope so that the geotextile can be installed on the slope; a foundation stone installation step of installing a foundation stone at the bottom of the slope so that a space can be formed between the lower slope formed at the bottom of the slope and the rear of the vertical block; a vertical block construction step of vertically constructing a vertical block above the foundation stone; a gravel filling step of laying gravel to conform to the lower slope in the space; a side block installation step of installing a side block on the filled gravel; a fixing device installation step of assembling and installing a fixing device on the geotextile; a sand and gravel filling step of filling sand and gravel between the fixing devices and compacting so that the fixing device can be firmly fixed and drained smoothly; and a slope block construction step in which the slope block is constructed on the right slope of the side block and the slope while the fixing device installed on the geotextile and the slope block are bound and fixed using a binding means. Effects of the invention

[0015] The gabion retaining wall construction method of the present invention provides the following effects.

[0016] - Provides the effect of enabling slope blocks constructed on an inclined surface by means of a fixing means to be stably installed and fixed without slippage.

[0017] - By forming a bulkhead in the vertical and inclined blocks, the front and rear sections can be stably supported, and the effect of preventing bending is provided.

[0018] - Vertical and inclined blocks can be installed in a zigzag arrangement using bulkheads, which distributes the load to ensure stability and allows for construction accuracy by positioning the vertical and inclined blocks in precise locations.

[0019] - The overall weight can be reduced by forming the bulkhead to be 1 / 3 to 2 / 3 smaller than the height of the vertical and inclined blocks.

[0020] - By creating holes in the upper and lower parts of the vertical and inclined blocks, the blocks constructed with pins can be easily installed in the correct position, providing the effect of reducing construction time.

[0021] - By embedding the drainage pipe in the foundation stone, water flows down to the bottom of the slope and enters the drainage pipe for smooth drainage. Since the drainage pipe is not exposed to the outside, damage during gabion retaining wall construction can be prevented. Furthermore, after the gabion retaining wall is constructed, the drainage pipe does not directly bear the load of the gabion retaining wall, thereby preventing damage.

Specific details for implementing the invention

[0023] In the following, the technical methods of the embodiments of the present invention are to be clearly and completely explained by combining them with the accompanying drawings. Of course, it is obvious that the described embodiments are merely preferred embodiments of the present invention and do not represent all embodiments. According to the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative labor fall entirely within the scope of protection of the present invention.

[0024] The configuration of the present invention will be explained below with reference to the attached drawings.

[0025] FIG. 1 is a flowchart showing a first embodiment of the gabion retaining wall construction method provided by the present invention.

[0026] The present invention relates to a method for constructing a gabion retaining wall (100) using blocks on a slope (S) of an embankment or cut slope, and is broadly composed of a geotextile installation step, a foundation stone installation step, a vertical block construction step, a gravel filling step, a side block installation step, and a slope block construction step.

[0027] ① Geotextile installation stage (S100)

[0028] : A step in which a geotextile (200) is installed on a slope (S) of an embankment or cut slope by covering the slope (S) with a geotextile (200) and compacting the slope (S) by applying pressure using a backhoe or crane equipment (not shown).

[0029] At the bottom of the above-mentioned inclined surface (S), a lower inclined surface (S1) is formed that is inclined more significantly than the angle of inclination of the inclined surface (S).

[0030] The above geotextile (200) is generally made from synthetic polymer raw materials such as polypropylene (PP) or polyester (PET), processed into a woven and needle-punched nonwoven fabric, and is used as a protective, filtration, reinforcement, drainage, stabilization, and separation layer to replace various terrains such as soil, rock, and sand. It is capable of providing performance such as UV resistance and thermal bonding, and can improve the stability of civil structures such as protecting slopes (S). It is used to provide erosion control or assist in drainage. The geotextile (200) is installed on a slope (S) to increase shear strength and bearing capacity and reduce permeability by compacting the slope (S) by applying pressure to the geotextile (200) covered on the slope (S) using backhoe or crane equipment (not shown).

[0031] Figure 2 illustrates a drawing showing the composition of the foundation stone.

[0032] ② Foundation stone (210) installation step (S110)

[0033] A foundation stone (310) is installed at the bottom of the lower slope (S1) so that a space (A) can be formed between the lower slope (S1) and the rear of the vertical block (300).

[0034] The above foundation stone (210) is intended to construct a vertical block (300) upward, so that the vertical block (300) can be installed accurately horizontally and vertically.

[0035] A perforated pipe installation groove (220) is formed in the foundation stone (210) so that a drainage perforated pipe (600) can be connected in the longitudinal direction, and the drainage perforated pipe (600) can be connected thereto in the longitudinal direction.

[0036] That is, the perforated pipe installation groove (220) is configured to compensate for the problem that the drainage perforated pipe (600) is damaged during the installation process when the drainage perforated pipe (600) is buried at the bottom of the slope to install the drainage perforated pipe (600), or that the drainage perforated pipe (600) made of PVC is damaged because it cannot withstand the load of the gabion retaining wall (100) after the gabion retaining wall (100) is constructed. This configuration allows the drainage perforated pipe (600) to be stably installed in the perforated pipe installation groove of the foundation stone and prevents the drainage perforated pipe (600) from being damaged by the load of the block during the installation process or after construction is completed.

[0037] At this time, the above-mentioned drainage pipe (600) is provided in a configuration wrapped in non-woven fabric (620) to prevent soil from entering.

[0038] The above drainage pipe (600) is generally configured such that several holes (610) are formed on the outer surface to allow water to flow into and drain, and to prevent soil from flowing into these holes (610), a non-woven fabric (620) is wrapped around the outer surface.

[0039] ③ Vertical block construction stage (S200)

[0040] : The vertical block construction step is a step of constructing a vertical block vertically on top of a foundation stone (210) so that a space (A) can be formed between the lower slope surface (S) on which the geotextile (200) is installed and the rear of the vertical block (300) so that the foundation stone (210) can be installed as described above can be positioned on the upper side of the foundation stone (210).

[0041] Figure 3 shows a drawing illustrating the configuration of a vertical block or an inclined block, and Figure 4 shows a cross-sectional view of Figure 2.

[0042] The above vertical block (300) has front and rear drainage holes (310) formed at regular intervals on the front and rear sides to allow water flowing into the interior to be drained to the outside, and binding holes (320) are formed on both sides so that vertical blocks (300) constructed by connecting reinforcing bars or structural steel can be connected by applying at least one of total connection, left-right connection, or top-bottom connection, and upper and lower connecting pin holes (340) (350) are formed so that a fixing pin (330) can be inserted to connect the vertical block (300) and the adjacent vertical block (300) on the upper and lower sides.

[0043] That is, the vertical block (300) is configured to form a connecting pin hole (340)(350) so as to be mutually connected with the vertical block (300) stacked by the fixing pin (330).

[0044] The above vertical blocks (300) can be constructed in a grid shape, but if the vertical blocks (300) are constructed in a grid shape, the vertical blocks (300) installed at the bottom may receive a large load. Therefore, to compensate for this, a partition wall (360) connecting the front and rear sides is formed so that the load is distributed and stability is ensured.

[0045] The above bulkhead (360) is structured to connect the front and rear sides to prevent bending of the front and rear sides of the vertical block (300), and is configured to be lightweight so as to reduce the overall weight of the vertical block (300) by forming the connected height (H1) to be 1 / 3 to 2 / 3 lower than the height (H) of the vertical block, and is configured to be connected by the lower connecting pin hole (350) and the fixing pin (330) of the vertical block (300) at the top, so as to be connected by accurately confirming the installation position of the vertical block (300) to be connected at the top.

[0046] ④ Gravel filling stage (S210)

[0047] : This is the step of filling gravel (G) into the space (A) formed between the lower slope surface (S1) and the rear of the vertical block (300).

[0048] Gravel (G) filling can be filled on the lower slope to a height similar to the bottom of the slope (S).

[0049] In the case of the gravel layer filled as described above, it provides the functionality to naturally induce and discharge water flowing in from the slope (S).

[0050] ⑤ Side block installation step (S300)

[0051] : It consists of the step of installing side blocks on the upper side of the gravel layer filled in the lower slope (S).

[0052] Figure 5 illustrates a drawing showing the configuration of the side block.

[0053] The above side block (400) is installed on filled gravel (G), and a slanted left sloped surface (410) is formed on the left side so as to be supported by contacting the rear surface of the vertical block (300), a slanted right sloped surface (420) is formed on the right side, and several drainage holes (430) are formed at the bottom so as to drain water.

[0054] In the above left and right inclined surfaces (410) (420), a binding hole (440) is formed so that the vertical block, side block (400) and inclined surface block (500) can be fastened with reinforcing bar or structural steel.

[0055] ⑥ Slope block construction stage (S400)

[0056] : A step of constructing inclined surface blocks (500) in a grid or zigzag shape on the right inclined surface (420) and the inclined surface (S) of the above side block (400).

[0057] The above-mentioned inclined surface block (500) has drainage holes (510) formed at regular intervals on the front and rear sides so that water flowing into the interior can be drained to the outside, and binding holes (520) are formed on both sides so that inclined surface blocks (500) constructed by connecting reinforcing bars or structural steel can be connected by applying at least one of total connection, left-right connection, or upper-lower connection, and upper-lower connection pin holes (540) (550) are formed so that a fixing pin (330) can be inserted to fix the inclined surface block (500) and the adjacent inclined surface block (500) to the upper and lower sides, and a partition wall (560) is formed connecting the front and rear sides so that the inclined surface blocks (500) are constructed in a zigzag arrangement.

[0058] That is, the inclined surface block (500) is configured to form a connecting pin hole (540)(550) so as to be mutually connected with the inclined surface block (500) stacked by the fixing pin (330).

[0059] The above bulkhead (560) is structured such that the front and rear sides are connected to prevent bending of the front and rear sides of the inclined surface block (500), and the connected height (H1) is formed to be 1 / 3 to 2 / 3 lower than the height (H) of the inclined surface block (500) to reduce the overall weight of the inclined surface block (500), thereby making it lightweight. A bulkhead connecting pinhole (570) is formed on the upper side so that it can be connected to the lower connecting pinhole (550) of the inclined surface block (500) with a fixing pin, and the installation position of the inclined surface block (500) to be connected to the upper side is accurately confirmed, and then the construction method of the first embodiment of the present invention is completed.

[0060] FIG. 6 is a flowchart showing a second embodiment of the gabion retaining wall construction method provided by the present invention.

[0061] The construction method of the second embodiment of the present invention is a construction method for preventing the phenomenon of a slope block (500) being pushed out when constructed on a slope (S) with a high slope angle or a slope (S) of soil with a high clay ratio, and is broadly composed of a geotextile installation step, a foundation stone installation step, a vertical block construction step, a gravel filling step, a side block installation step, a fixing means installation step, and a slope block construction step.

[0065] : It consists of a step in which a fixing means (700), such as a steel rod or an anchor, is installed perpendicularly to the inclined surface (S).

[0109] This method of constructing a gabion retaining wall (100) is intended to install a retaining wall by constructing blocks on a slope (S) of an embankment or cut slope, and can be installed on a slope (S) with a steep slope or soil with a high clay ratio to be firmly fixed without slipping.

[0110] The present invention allows a drainage pipe (600) to be embedded in the foundation stone (400) so that rainwater or water can flow to the bottom of the lower slope (S1) and enter the drainage pipe (600) to be drained smoothly, and the drainage pipe (600) is not exposed to the outside so that it can be prevented from being damaged during the work of the gabion retaining wall (100), and after the construction of the gabion retaining wall (100), the drainage pipe (600) does not directly receive the load of the gabion retaining wall (100) so that it can be prevented from being damaged.

[0111] The present invention allows for stable support of the front and rear sections by forming a partition wall (360)(560) on the vertical and inclined surface blocks (300)(500) and prevents bending phenomena. The vertical and inclined surface blocks (300)(500) can be installed in a zigzag arrangement by means of the partition wall (360)(560), thereby distributing the load to ensure stability and ensuring that the vertical and inclined surface blocks (300)(500) are positioned at the correct location, thereby providing accuracy in construction.

[0112] The foregoing is merely a preferred embodiment formed as a slight improvement of the present invention and is by no means intended to limit the present invention; any equivalent variation or equivalent modification made to the improvement of the present invention, or any combination not illustrated in this specification, should be included within the scope of protection of the present invention.
