Description

{Retaining wall structure capable of linear variation in horizontal and vertical directions}

The present invention relates to a retaining wall structure, and more particularly, to a retaining wall structure capable of horizontal and vertical linear variation, in which a panel installed in a horizontal direction is linearly varied to correspond to a cut site by coupling a side rotation protrusion of a panel to a side rotation groove of another panel, or a panel installed in a vertical direction is linearly varied to correspond to a cut site by coupling a lower rotation protrusion of a panel to an upper rotation groove of another panel, and then the angle of a permanent anchor is adjusted by an angle adjustment member, the permanent anchor is passed through an anchor insertion groove to support soil pressure, and a finishing device is installed at the end of the permanent anchor to tension the permanent anchor.

In general, during the process of carrying out various civil engineering works such as road construction, housing complex development, waterway and embankment construction, retaining walls are constructed to prevent collapse due to soil loss.

At this time, retaining walls are being implemented using various construction methods, but they can be typically divided into the construction method of retaining walls on fill land and the construction method of retaining walls on cut land, and mainly, the construction method of retaining walls using blocks, couplers, and geogrids is being applied.

However, due to the nature of our country's land with many mountains, there are relatively many cut areas in the process of carrying out civil engineering works such as road construction, housing complex development, waterway and embankment construction, so the method of constructing retaining walls using blocks and underground bolts is widely applied.

And, for the retaining wall structure constructed on the cut site, the original ground is cut to form a cut slope so that a slope is formed, holes are drilled at a predetermined interval on the cut slope, ground bolts (anchors) are inserted, and grouting is injected. After that, blocks that are vertically stacked on the foundation surface are connected to the ground bolts exposed on the cut slope so that the overturning moment applied to the blocks is supported, thereby preventing the collapse of the retaining wall.

Patent Document 1 shows a conventional strength-reinforced retaining wall panel, and with reference thereto, a panel body is provided with an inclined nail hole formed in the central portion of the front side, an insertion groove formed on the upper surface, and an insertion protrusion formed on the lower surface corresponding to the insertion groove, and a soil nail is formed that enters the nail hole of the panel body and has its end embedded in a cut slope, thereby forming a reinforcing panel that finishes the front side of the panel body.

At this time, the fitting projection of the panel body is fixed into the fitting groove of another panel body, and multiple panel bodies are vertically stacked and combined, and in that state, soil nails are inserted at a set angle through the nail hole so that they are buried in the cut slope, and then the space between the cut slope and the panel body is filled with reinforcing soil, and then the entire surface of the panel body is finished with a reinforcing panel, thereby constructing a retaining wall.

However, in the patent document 1 as described above, since the panel bodies are simply laminated and joined in the vertical direction, a void is formed between the panel bodies and the cut slope, and the amount of reinforced soil fill increases depending on the area of the void between the panel bodies and the cut slope, which increases the construction cost, and since it is impossible to vary the installation state of the panel bodies to correspond to the shape of the cut slope, the installation state of the panel bodies is limited to the vertical direction, and furthermore, since the inclination angle of the soil nails embedded in the cut slope is fixed to correspond to the inclination angle of the nail hole, it is impossible to adjust the inclination angle of the soil nails, and accordingly, there is a problem that the construction of the retaining wall is difficult and the reliability of the product is reduced.

The above-mentioned catch (242) is formed to have a one-way pressing operation structure that is pressed against the inner wall surfaces of the first connecting groove (211), the second connecting groove (222), and the third connecting groove (231) by the connecting member (240) moving downward.

The above-mentioned catch (242) is pressed as it enters the third connecting groove (231) formed on the upper portion of the above-mentioned tensile member (230), and at the moment it reaches the above-mentioned assembly groove (232a), it enters the above-mentioned assembly groove (232a) and maintains a state of being caught in the above-mentioned assembly groove (232a).

The above-mentioned catch (242) is positioned within the above-mentioned assembly groove (232a), and when the above-mentioned connecting member (240) is pressed downward, it is pressed against the inner wall surface of the above-mentioned third connecting groove (231), detached from the above-mentioned assembly groove (232a), and then restored to its original state the moment it reaches the above-mentioned third catch groove (232), and is inserted and caught within the above-mentioned third catch groove (232).

The above-mentioned catch (242) is prevented from being separated from the insertion groove (241) by having one end caught on the inner wall surface of the insertion groove (241).

The above elastic spring (243) is compressed by being pressed against the catch (242) that enters the insertion groove (241), and at the moment when the catch (242) reaches the first catch groove (213), the second catch groove (223), the third catch groove (232) or the assembly groove (232a), the catch (242) is pushed out of the insertion groove (241).

The angle adjustment member (300) passes through the end of the permanent anchor (200) exposed to the outside of the anchor insertion hole (105), and is inserted and joined within the anchor insertion hole (105) to adjust the inclination angle of the permanent anchor (200).

The above angle adjustment member (300) passes through the spiral portion (221) formed in the upper mandrel (220) of the permanent anchor (200), and then rotates at a set angle within the angle adjustment groove (105a) of the anchor insertion hole (105) to adjust the inclination angle of the permanent anchor (200).

The above angle adjustment member (300) is formed to correspond to the shape of the angle adjustment groove (105a) and adjusts the inclination angle of the permanent anchor (200) within the angle adjustment groove (105a).

The above angle adjustment member (300) can be formed in any one of a hemispherical, conical or semicircular shape to correspond to the shape of the angle adjustment groove (105a), and this shape can be variously changed to correspond to the shape of the angle adjustment groove (105a).

The closing device (400) is located at the rear end of the angle adjustment member (300) and is connected to the end of the permanent anchor (200) to provide tensile force to the permanent anchor (200) buried in the ground.

The above closing device (400) is connected to the spiral portion (221) of the upper mandrel (220) exposed to the outside of the anchor insertion hole (105) through the angle adjustment member (300), thereby simultaneously tensioning the fixing portion (210), the connecting member (240), and the tensioning portion (230) through the upper mandrel (220).

The above closing device (400) is connected to the spiral portion (221) of the upper mandrel (220), and includes a tension nut (401) that tensions the spiral portion (221) toward the outside of the anchor insertion hole (105) by rotational tightening, and a cover (402) that is fixedly installed on the front surface of the panel (100) and covers the end of the spiral portion (221) exposed to the outside of the anchor insertion hole (105) and the tension nut (401).

The above tension nut (401) is tightened by rotation by a worker, thereby forcing the spiral part (221) to be pulled out of the anchor insertion hole (105), thereby applying tensile force to the permanent anchor (200).

The above cover (402) covers the end of the spiral part (221) and the tension nut (401), thereby preventing the tension nut (401) from being loosened from the spiral part (221) due to external impact or preventing rainwater or dust from flowing into the gap between the tension nuts (401).

The horizontal and vertical linearly variable retaining wall structure according to the present invention configured as described above is used as follows.

Below, a detailed description of the process of cutting a slope, drilling a hole (11) in the slope, and pouring reinforcing soil between the structure installed on the cut land (10) and the cut land (10) to allow curing is omitted.

And, the above panel (100) can be installed in a vertical or horizontal direction depending on the construction method, and can be installed in multiple horizontal directions along the perimeter of the inclined cut land (10) so as to be linearly variable, or can be installed in a vertical direction so as to be stacked so as to be linearly variable. Hereinafter, the horizontal linearly variable installation and the vertical linearly variable installation will be described separately.

First, a permanent anchor (200) corresponding to the depth of the perforation (11) of the inclined cut (10) is provided, and the permanent anchor (200) is introduced into the perforation (11) so that one end of the permanent anchor (200) is positioned on the bottom surface of the perforation (11).

At this time, the permanent anchor (200) is composed of a fixing portion (210), a connecting member (240), a tensile portion (230), and an upper manifold (220), and is provided with the fixing portion (210), and the connecting member (240) is inserted into the first connecting groove (211) of the fixing portion (210), thereby connecting and fixing the fixing portion (210) and the connecting member (240), but the third connecting groove (231) formed at the lower portion among the third connecting grooves (231) of the tensile portion (230) is combined with the upper portion of the connecting member (240), thereby sequentially combining the fixing portion (210), the connecting member (240), and the tensile portion (230) from the lower portion.

Then, the lower part of another connecting member (240) is inserted and connected into the third connecting groove (231) formed on the upper part of the tensile member (230), and then the tensile member (230) and the connecting member (240) are sequentially connected in the same manner as above.

At this time, the number of connections between the connecting member (240) and the tensile member (230) is proportional to the depth of the perforation hole (11) in the cut soil (10).

Next, the second connecting groove (222) of the upper mandrel (220) is inserted and connected to the upper end of the connecting member (240) located at the uppermost end among the plurality of connecting members (240), and in that state, the spiral portion (221) formed at the upper end of the upper mandrel (220) is exposed to the perforation (11) of the cut-off (10).

Here, the connecting member (240) forms a catch (242) on its outer surface, and the catch (242) enters the first connecting groove (211), the second connecting groove (222), and the third connecting groove (231) formed at the lower portion of the tensile member (230), and while being pressed against the inner wall surfaces of the first connecting groove (211), the second connecting groove (222), and the third connecting groove (231), enters the insertion groove (241) and compresses the elastic spring (243).

And, when the catch projection (242) reaches the first catch groove (213), the second catch groove (223) and the third catch groove (232) in the third connection groove (231) formed at the lower portion of the first connection groove (211), the second connection groove (222) and the tensile portion (230), the elastic spring (243) is exposed to the outside of the insertion groove (241) by the restoring force of the elastic spring (243) and is caught by the first catch groove (213), the second catch groove (223) and the third catch groove (232), so that the connecting member (240) is connected and fixed to the first connection groove (211), the second connection groove (222) and the third connection groove (231).

Meanwhile, the catch (242) of the connecting member (240) that enters the third connecting groove (231) formed on the upper portion of the tensile portion (230) is pressed against the inner wall surface of the third connecting groove (231) and enters the insertion groove (241), and then, at the moment when the catch (242) reaches the assembly groove (232a) of the third connecting groove (231), it is exposed to the outside of the insertion groove (241) and is caught and fixed in the assembly groove (232a).

Then, the connecting member (240) is maintained in a temporarily assembled state within the third connecting groove (231), and in this state, when the permanent anchor (200) is introduced into the perforation (11) of the cut-off (10) so that the permanent anchor (200) is pressed downward by its own weight, the engaging projection (242) located within the temporary assembly groove (232a) of the third connecting groove (231) is pressed against the inner wall surface of the third connecting groove (231) by the connecting member (240) moving downward by its own weight, and then is restored to its original state upon reaching the third engaging groove (232) and is engaged and fixed within the third engaging groove (232).

In particular, while the above-mentioned catch (242) is moved from the above-mentioned assembly groove (232a) to the above-mentioned third catch groove (232), the above-mentioned connecting member (240) is moved downward to rotate the fastening portion (233) of the above-mentioned tensile portion (230), and at this time, the fastening portion (233) is spread radially and is fitted closely to the wall of the perforation portion (11).

That is, as the connecting member (240) moves downward, it rubs against the outer surface of the rotary cam (233a) of the connecting member (233) to rotate the rotary cam (233a) toward the outside of the tensile member (230), and at this time, the wing piece (233b) formed integrally with the rotary cam (233a) is spread by the rotary cam (233a), and the end of the wing piece (233b) is fixedly fitted to the wall of the perforation (11), thereby preventing the tensile member (230) from being separated from the perforation (11).

Here, in the process of introducing the permanent anchor (200) into the perforation (11), a hose (not shown) is simultaneously introduced into the perforation (11), and grouting is injected into the perforation (11) underground through the hose (not shown), thereby filling the perforation (11) with grouting.

At this time, the grout injected into the perforation (11) is injected so that it overflows outside the perforation (11) to check whether the grouting of the perforation (11) is filled.

Then, by hardening the grout within the perforation (11), the catch (212) of the fixing portion (210) is caught and fixed within the hardened grout.

Next, when the insertion of the permanent anchor (200) into the perforation (11) as described above is completed, a plurality of panels (100) are installed horizontally or vertically depending on the construction site of the inclined cut land (10), and the horizontal installation or vertical installation of the panels (100) will be described below.

First, when installing a plurality of panels (100) in a horizontal direction, a plurality of support members (108) are installed along the ground around the inclined cut site (10), and a panel (100) is installed on each of the support members (108) so that the panel (100) surrounds the wall of the cut site (10).

At this time, the lower rotation protrusion (102) formed at the lower end of the panel (100) is fixedly joined to the rotation guide groove (108a) of the support member (108) so that the lower end of the panel (100) is fixed to the support member (108), and in that state, the side rotation protrusion (101) of the panel (100) is joined to the side rotation groove (103) of another panel (100), thereby connecting the panel (100) and the other panel (100).

Here, when the side rotation protrusion (101) is rotated toward the wall of the cut site (11) based on the side rotation groove (103) and the position of the support (108) supporting the lower rotation protrusion (102) is changed, the plurality of panels (100) installed in the horizontal direction are linearly deformed to correspond to the shape of the wall of the cut site (10), so that the panels (100) surround the periphery of the cut site (10).

At this time, the spiral part (221) formed in the upper mandrel (220) of the permanent anchor (200) inserted into the perforation (11) through the anchor insertion hole (105) of the panel (100) is exposed so that the spiral part (221) is exposed to the outside of the panel (100).

In addition, a support bar (107) having one end in close contact with the wall of the cut site (10) is installed in the fastening hole (106) of the panel (100), and by rotating the support bar (107), the distance between the wall of the cut site (10) and the panel (100) is adjusted by moving the panel (100) away from the wall of the cut site (10) or moving it closer to the wall of the cut site (10).

Here, the above fastening holes (106) are formed in multiple numbers around the edge of the anchor insertion hole (105) of the panel (100), and by rotating the multiple support bars (107) to adjust the distance between the wall of the cut site (10) and the panel (100), the panel (100) is supported by the support bars (107) and maintains a state of being spaced apart from the wall of the cut site (10) by a set distance.

And, by introducing a wire (W) into the horizontal wire groove (100a) of the panel (100) that is linearly variable in the horizontal direction and connecting each panel (100) with the horizontal wire groove (100a), the panels (100) are prevented from being separated from each other by external impact or the side rotation projection (101) of the panel (100) from being separated from the side rotation groove (103) of another panel (100).

On the other hand, when installing a plurality of panels (100) in a vertical direction, a support member (108) is placed on the ground of a sloping cut site (10), and a panel (100) is placed on the support member (108) so that the panel (100) is positioned on the wall of the cut site (10).

At this time, the lower rotation protrusion (102) of the panel (100) is positioned close to the wall of the cut site (10) while being seated in the rotation guide groove (108a) of the support member (108) and rotating based on the rotation guide groove (108a).

Next, the lower rotation protrusion (102) of another panel (100) is laminated and mounted on the upper rotation groove (104) of the panel (100) mounted on the support (108), and in that state, the lower rotation protrusion (102) of the panel (100) laminated as described above is rotated based on the upper rotation groove (104), so that the inclination angle of the laminated panel (100) corresponds to the shape of the wall of the cut site (10).

Afterwards, the lower rotation protrusion (102) of another panel (100) is laminated and installed on the upper rotation groove (104) of the panel (100) laminated in the same manner as above, and then the panel (100) is rotated as above, so that the plurality of laminated panels (100) are linearly deformed in the vertical direction.

At this time, the spiral part (221) formed in the upper mandrel (220) of the permanent anchor (200) inserted into the perforation (11) through the anchor insertion hole (105) of the panel (100) is exposed so that the spiral part (221) is exposed to the outside of the panel (100).

Here, a support bar (107) having one end in close contact with the wall of the cut site (10) is installed in the fastening hole (106) of the panel (100), and by rotating the support bar (107), the distance between the wall of the cut site (10) and the panel (100) is adjusted by moving the panel (100) away from the wall of the cut site (10) or moving it closer to the wall of the cut site (10).

Here, the above fastening holes (106) are formed in multiple numbers around the edge of the anchor insertion hole (105) of the panel (100), and by rotating the multiple support bars (107) to adjust the distance between the wall of the cut site (10) and the panel (100), the panel (100) is supported by the support bars (107) and maintains a state of being spaced apart from the wall of the cut site (10) by a set distance.

Here, after the plurality of laminated panels (100) are linearly varied in the vertical direction to correspond to the shape of the wall of the cut-off site (10), a wire (W) is passed through the vertical wire groove (100b) of the panel (100) to connect the plurality of panels (100) linearly varied in the vertical direction, thereby preventing the panels (100) that are laminated and connected from widening or the lower rotation protrusion (102) of the panel (100) from being separated from the upper rotation groove (104) of another panel (100).

That is, the panel (100) of the present invention can be linearly varied in the horizontal direction by connecting the side end rotation projection (101) of the panel (100) having a single shape to the side end rotation groove (103) of another panel (100), depending on the construction site of the cut land (10), or the panel (100) installed in multiple pieces can be linearly varied in the vertical direction by connecting the lower rotation projection (102) of the panel (100) having a single shape to the upper rotation groove (104) of another panel (100), and then be stacked in the vertical direction.

Next, when the installation of the panel (100) is completed as described above, the angle adjustment member (300) is coupled to the angle adjustment groove (105a) of the anchor insertion hole (105), so that the spiral part (221) passes through the angle adjustment member (300), and in that state, the angle adjustment member (300) is rotated at a set angle within the angle adjustment groove (105a), thereby adjusting the tension angle of the spiral part (221).

At this time, the angle adjustment groove (105a) is formed in a hemispherical, conical or semicircular shape to guide the angle adjustment member (300) to rotate at a set angle.

Thereafter, the tension nut (401) of the closing device (400) is coupled to the spiral portion (221), and the tension nut (401) is rotated in that state to tighten the tension nut (401) to the spiral portion (221), so that the spiral portion (221) is tensioned by the tension nut (401), thereby tensioning the upper mandrel (220), the connecting member (240), the tension member (230), and the anchoring member (210). At this time, the upper mandrel (220), the connecting member (240), the tension member (230), and the anchoring member (210) are fixed to the grout hardened in the perforation (11), thereby preventing the permanent anchor (200) from being detached to the outside in the perforation (11).

And, the cover (402) of the closing device (400) is tightly fixed to the front of the panel (100) to cover the spiral part (221) and tension nut (401) exposed to the outside of the panel (100), thereby preventing dust, foreign substances or rainwater from penetrating between the tension nut (401) and the spiral part (221).

Then, the permanent anchor (200) is tensioned to maintain the panel (100) in close contact with the inclined cut site (10), and at this time, reinforcing soil is injected into the space between the panel (100) and the cut site (10), thereby completing the construction of the retaining wall.

As described above, the structure in which the panels (100) are installed horizontally or vertically in layers to allow a plurality of panels (100) to be linearly variable in the horizontal direction or linearly variable in the vertical direction to correspond to the shape of the wall of the cut site (10) is such that the lower rotation protrusion (102) of the panel (100) is connected to the upper rotation groove (104) so that the vertically stacked panels (100) can be freely linearly variable to correspond to the shape of the wall of the cut site (10) or the side rotation protrusion (101) of the panel (100) is connected to the side rotation groove (103) so that the horizontally connected panels (100) can be freely linearly variable to correspond to the shape of the wall of the cut site (10). The empty space area between the panel (100) and the cut site (10) is reduced, so that the amount of reinforced soil filled into the empty space is significantly reduced, and the reinforced soil is relatively weaker than the cut site (10). The amount of landfill is reduced.

The horizontal and vertical linearly variable retaining wall structure according to the present invention described above is not limited to the above-described embodiment, and anyone with ordinary skill in the art can make various modifications and implement the same without departing from the gist of the present invention claimed in the claims below, to the extent that it has the technical spirit thereof.
