Description

Retaining wall structure

The present invention relates to a retaining wall structure, and more particularly, to a retaining wall structure in which soil, sand and a plurality of construction units inserted with seedlings are engaged therein.

In general, a retaining wall means a structure installed to secure the robustness and stability by preventing soil loss in an area where soil collapse easily occurs due to soil pressure such as a roadside or a mountain foot. .

At present, the retaining wall has various installation methods and types, and the most conventional method is to install a steel mesh on the construction site and inject the mixed concrete to solidify it. However, this method has a disadvantage that the construction time is long because the construction scale is not only very large, but also the difficulty of the construction is high, and the time to solidify the mixed concrete is relatively long.

In addition, the retaining wall structure made of concrete is restricted to cover the soil, and it is desired to be lost due to wind or water invasion. Also, the efficiency of environmental greening is very low, and furthermore, it is difficult to preserve the soil properly.

In order to make up for the shortcomings of the existing retaining wall structure, a method of stacking the bag and completing the retaining wall is frequently used. In such a method, after filling the bag with sand / dirt, it is vertical. Or it is a structure that completes the retaining wall by stacking the horizontally connected to each other, at this time by installing the connection fixing parts between the adjacent sack, so that the sack can be fixed more firmly without slipping each other.

However, the retaining wall structure, which is completed by connecting and fixing adjacent subsidiaries using the connection fixing parts, does not have strength enough to withstand heavy rain and wind, and the wall is easily damaged in a poor environment such as sand wind (sand wind). I found the problem that this occurs.

Referring to these drawings, the retaining wall structure according to the embodiment of the present invention includes a plurality of horizontal side construction units 11, a plurality of vertical side construction units 11c, a coupling member 20, and a coupling guide member 30. do.

The horizontal side construction unit 11 is a plurality of sandbags or trowels piled on the ground 12, the vertical side construction unit 11c is a plurality of sandbags or trowels stacked on the horizontal side construction unit 11. to be. The construction unit 11 is made of a durable geotextile material, a fabric of water can flow through the construction unit 11, the seeds can germinate. The building unit in the present embodiment may be understood as a soil bag filled with soil or sand.

Hereinafter, for convenience of description, a pair of horizontal side construction units 11 and a vertical side construction unit 11c positioned on the pair of horizontal construction units 11 shown in FIG. 1 will be described.

The coupling member 20 is a pair of horizontal side construction unit 11 is adjacent to each other the first horizontal side construction unit (11a) and the second horizontal side construction unit (11b) and the first and second horizontal side construction unit It is fitted to each surface of the vertical side construction unit 11c arrange | positioned on 11a, 11b, and binds the 1st and 2nd horizontal side construction unit 11a, 11b and the vertical side construction unit 11c simultaneously.

That is, when the vertical side construction unit 11c is disposed on the first and second horizontal side construction units 11a and 11b, the coupling member 20 has a coupling protrusion 24 formed on one surface of the coupling member 20. The first and second horizontal side construction units 11a and 11b and the vertical side construction unit 11c forming the surface of the retaining wall penetrate each surface thereof and are fixed to the surface of the retaining wall.

At this time, the coupling guide between the first and second horizontal-side construction unit (11a, 11b) and the vertical-side construction unit (11c) in order to maintain the coupling fixing force between the coupling member 20 and the construction unit (11). The member 30 is disposed.

2 and 3, the first and second horizontal side construction units 11a and 11b are disposed on the ground 12 and are coupled to the first and second horizontal side construction units 11a and 11b. Guide member 30 is seated. Thereafter, the vertical side construction unit 11c is positioned on the first and second horizontal side construction units 11a and 11b and the coupling guide member 30. At this time, one end of the coupling guide member 30 is arranged to protrude from the front of the first and second horizontal side construction unit (11a, 11b) and the vertical side construction unit (11c), a portion of the coupling guide member 30 This is because the coupling member 20 passes or is inserted.

When the coupling guide member 30 is disposed between the construction units 11 as described above, one end of the coupling guide member 30 passes through the coupling hole 22 of the coupling member 20. At this time, the coupling guide member 30 and the coupling member 20 is forcibly fitted so that they can be coupled and fixed without using a separate fixing member or adhesive.

At this time, the coupling member 20 is pushed toward the construction units 11 until the coupling member 20 is in contact with one surface of the construction units 11. As such, when the coupling member 20 is pushed toward one surface of the construction units 11, the coupling protrusion 32 of the coupling member 20 penetrates one surface of each of the construction units 11, and each construction unit 11 is formed. Coupling protrusion 32 penetrating one surface of the) is bound to the soil or sand inside the construction unit 11 and can be fixed to the construction unit 11 built on the ground (12).

Looking at the coupling member 20 according to the above configuration, the coupling member 20 includes a body 26, the coupling hole 22, the coupling protrusion 24.

When the coupling member 20 is installed on the retaining wall surface, the body 26 is configured to interview the first and second horizontal side construction units 11a and 11b and one surface of the vertical side construction unit 11c.

The coupling hole 22 is formed in the body 26, the one end of the above-mentioned coupling guide member 30 is configured to penetrate through. At this time, the coupling guide member 30 is configured to be forcibly coupled to the coupling hole 22. To this end, the coupling hole 22 is formed to be smaller than or equal to the width of the cross section of the coupling guide member 30, and is preferably formed to have the same shape as that of the cross section of the coupling guide member 30.

The coupling protrusion 24 penetrates one surface of the construction units 11 when the body 26 contacts one surface of the first and second horizontal side construction units 11a and 11b and the vertical side construction unit 11c. It is configured to be inserted into the construction unit (11). Since the construction unit 11 is formed of a fabric material, the coupling protrusion 24 is formed of a material that can penetrate the surface of the construction unit 11, and more easily constructed to penetrate the surface of the construction unit 11. It is preferable that an end portion facing the surface of the unit 11 is formed as a tip, but the shape, length, and the like of the coupling protrusion 24 may be changed according to conditions.

On the other hand, the coupling guide member 30 to be fitted, mounted in the coupling hole 22 of the coupling member 20 includes a plurality of coupling protrusions (32). The coupling protrusion 32 may be formed along the outer circumference of the coupling guide member 30. When the coupling member 20 is fitted, the coupling protrusion 32 contacts the inner surface of the coupling hole 22 and the coupling guide 20. It is to increase the binding force between the members (30).

At this time, the coupling protrusion 32 is formed at the end center of the coupling guide member 30. The coupling guide member 30 is one end of the coupling guide member 30 is disposed away from one surface of the construction unit 11, is fitted in the coupling hole 22 of the coupling member 20 and the coupling member 20 The coupling protrusion 32 is preferably formed at the center of one end of the coupling guide member 30 in order to improve the binding with the coupling member 20 because it is coupled to the coupling member 20.

In addition, the coupling protrusion 32 is preferably formed at both ends of the coupling guide member (30). When the coupling guide member 30 is positioned on the first and second horizontal side construction units 11a and 11b, the coupling member 20 can be engaged with the coupling guide member 30 even when the coupling guide member 30 is seated regardless of the direction. do.

On the other hand, the coupling guide member 30 of the retaining wall structure of the first embodiment of the present invention is formed in the shape of a circular bar (bar), the coupling hole 22 of the coupling member 20 is the shape of the coupling guide member 30 For example, but the coupling guide member 30 is formed in the shape of a triangular pillar, the coupling hole 22 may be formed as a triangular hole, of course.

By the retaining wall structure of the above configuration, the coupling member for fixing the building unit can simultaneously bind the building units located on different layers, thereby improving the robustness of the surface of the retaining wall.

Further, the coupling guide member located between the construction unit and the coupling member for binding the construction unit are coupled by interference fit to improve the fixing force of the coupling member, thereby improving the rigidity of the construction unit forming the retaining wall.

On the other hand, Figure 6 is a perspective view showing a modification of the coupling guide member of FIG.

As shown in Figure 6, the coupling guide member 30 of the present invention is interposed between the first horizontal side construction unit (11a) and the second horizontal side construction unit (11b), the first and second horizontal side construction It may be formed longer than the length of the front and rear directions (refer to the direction axis of Figure 2) of the unit (11a, 11b). By the coupling guide member 30 formed as described above, the coupling member 20 is mounted in both the front direction and the rear direction of the first and second horizontal side construction units 11a and 11b and the vertical side construction unit 11. It can work.

As shown in FIG. 7 and FIG. 8, the coupling member 20 according to the modification is connected to the inner surface of the body 26 by a plurality of inner walls 25 connecting the outer surface of the body 26 and the inner center of the body 26. Is formed. At this time, between the inner wall 25 and the adjacent inner wall is formed as a hole 28 so that the deformed coupling member 20 is installed on one surface of the building unit 11 can be germinated inside the building unit (11) The growth of the plant is allowed to penetrate through the hole 28 to the outer wall of the retaining wall.

On the other hand, Figure 9 is a retaining wall structure according to a second embodiment of the present invention, Figure 10 is a perspective view showing an embodiment in which the coupling guide member of the second embodiment is installed in the horizontal side construction unit of FIG.

9 and 10, when the reference numerals illustrated in FIGS. 1 to 8 and the reference numerals illustrated in FIGS. 9 and 10 are the same, the same configuration is determined, and detailed description thereof will be omitted. .

Referring to the drawings, the coupling guide member 30A of the retaining wall structure according to the second embodiment of the present invention is located between the side surfaces of the first and second horizontal-side construction units 11a and 11b facing each other.

At this time, the coupling guide member 30A is formed in a square plate shape so as to be disposed between one side of the first horizontal side construction unit 11a and one side of the second horizontal side construction unit 11b. In particular, one end of the coupling guide member 30A is one of the bar-shaped coupling guide member 30A of the first embodiment of the retaining wall structure and the first and second horizontal side construction units 11a and 11b. It may be arranged to protrude from the surface.

On the other hand, as the coupling guide member 30A of the second embodiment of the present invention is formed in a plate shape, the coupling hole 22A of the coupling member 20 is preferably formed in a square shape.

In addition, a plurality of coupling protrusions 32 are formed on the surface of the coupling guide member 30A, so that when the coupling member 20 is coupled, the coupling holding force of the two members may be improved.

On the other hand, the coupling guide member 30A according to the second embodiment shown in the drawings is an example formed of a length shorter than the length before and after the first and second horizontal-side construction unit (11a, 11b) Like the coupling guide member 30 of the first embodiment, it is formed longer than the front and rear lengths of the first and second horizontal side construction units 11a and 11b to be perpendicular to the first and second horizontal side construction units 11a and 11b. Of course, the coupling guide member (30A) can be mounted on both the front and rear of the side construction unit (11c).

11 is a view showing a retaining wall structure constructed in accordance with another embodiment of the present invention.

Retaining wall structure according to another embodiment of the present invention is a structure that can further solidify the coupling between the construction unit consisting of the tonal and the field soil disposed behind the construction unit.

That is, in addition to the coupling of the construction units such as sack bag to withstand the load as the retaining wall structure, the coupling with the structures such as field soils built behind the construction unit is further increased.

For example, the retaining wall composed of the building units, which are the toners described above, may be referred to as the first retaining wall A, and the retaining wall for stacking the crushed stone layer or the site soil may be referred to as the second retaining wall B.

In the case of the retaining wall structure according to another embodiment of the present invention described below, a triangular shape is formed between the angular caps by a connecting member between the delta-shaped couplings (ie To form a delta shape), and may be combined with the crushed stone layer or the soil of the second retaining wall using a connecting member.

In detail, referring to FIG. 11, a retaining wall structure according to an embodiment of the present invention may include a first retaining wall A formed by stacking a plurality of building units made of soil or sand, and at least one rear of the first retaining wall A. FIG. It includes a second retaining wall (B) including a site soil layer.

In the case of the second retaining wall (B), when the retaining wall is constructed using a building unit such as sacking, it is equivalent to the pile of field soil or stone piled up by cutting the inclined surface. We propose a structure that can be closely combined with the construction unit.

The second retaining wall B may be variously constructed according to the topography of the retaining wall structure to be constructed, but the lowermost layer is composed of a crushed stone layer 101 such as gravel for drainage, and the upper portion of the crushed stone layer 101 The nonwoven drainage layer 100 is configured to suppress the introduction of a substance that prevents the drainage of foreign matters or the like into the chain layer 101.

In particular, the nonwoven drainage layer 100 helps the water seeping into the second retaining wall to drain laterally of the retaining wall. When the second retaining wall is positioned forward of the front of the first retaining wall and behind the first retaining wall, the water that has soaked into the second retaining wall by the nonwoven drainage layer 100 is drained laterally rather than forward and backward.

And, the nonwoven drainage layer 100 is to ensure a firm compaction when constructing the reinforcement soil (crushed stone, field soil, etc.) constituting the second retaining wall. That is, when constructing the spot soil on the crushed stone layer, if the drainage layer made of nonwoven fabric is placed on the crushed stone layer, and the stacked soil is piled up thereon, the nonwoven drainage layer indicates that the spot soil having a smaller volume than the crushed stone layer is introduced into the crushed stone layer. Because it prevents.

The nonwoven drainage layer 100 may suppress an increase in back water pressure, replace the geogrid used in the existing retaining wall structure, and may also secure drainage.

On the other hand, the site soil 102 to be compacted on the nonwoven drainage layer 100 can be piled on the site soil repeating the compacting several times according to the site situation, the building unit and the second retaining wall of the first retaining wall (A) The site soil 102 may be surrounded by an all-around strip 200 that allows the coupling of (B) to be tight.

In addition, the second retaining wall B may be configured with the all-around strip 200 and a straight strip 300 for coupling the material and the construction unit constituting the second retaining wall, such as a field soil or a crushed layer. These all-around strips 200 and straight strips 300 will be described in more detail together with the accompanying drawings.

In addition, the non-woven drainage layer 100 of the embodiment may be disposed between the all-around strip 200 and the straight strip 300 position, and facilitates drainage while making the compaction of the site soil during the construction of the site soil.

An all-around strip 200 and a straight strip 300 that couple the second retaining wall B and the first retaining wall A to each other will be described.

12 is a view showing the configuration of a connecting member that can be coupled to a straight strip according to this embodiment, Figure 13 is a view showing the appearance of a straight strip connecting tonal soil and earth soil as a construction unit according to this embodiment. .

According to the present embodiment, the straight strip 300 couples the sack of the first retaining wall and the field soil of the second retaining wall through the coupling member 20. The straight strip 300 may be made of a synthetic resin, by stacking the construction unit and the site soil in the field, by allowing the straight strip 300 to pass through the connection member, the coupling can be made.

The coupling member 20 of the embodiment includes a body 26 forming a body, a plurality of coupling protrusions 24 protruding from one surface of the body 26 to be inserted into the tonang, which is a construction unit, and the body. At least one strip fastening hole 40 formed in the (26).

The coupling member 20 further includes a coupling hole 22 through which the coupling guide member 20 described above may pass.

The straight strip 300 is a straight strip 300 into the strip fastening hole 40 when the coupling member 20 is coupled / inserted to the front surface of the first and second construction units in the construction layer. Pass).

Both ends of the straight strip 300 passed through the strip fastening hole 40 are coupled using a separate fastening member, etc., and are constructed so that a part of the site soil is wrapped by the straight strip 300.

When configured in this way, the upper and lower construction units are coupled to each other through the coupling member 20, the coupling / compaction between the site soil and the construction unit by the straight strip 300 is made. Through such a structure, not only the case of uneven settlement but also the structure of the tonang constituting the retaining wall structure are connected not only to them but also to the structures on the back such as the soil or the crushed stone layer. Even if a decay force occurs, it can serve as a solid retaining wall structure.

In addition, it is not necessary to construct the retaining wall by using the existing geogrid, and it is possible to achieve firm construction and smooth drainage of the retaining wall (second retaining wall) by the nonwoven drainage layer.

Meanwhile, FIG. 13 shows that one straight strip 300 is connected to one coupling member 20 so that a close density between the first retaining wall and the second retaining wall is achieved. As described above, the straight strip 300 may be coupled to only some of the coupling members of the coupling members mounted on the bag of the first retaining wall. In consideration of the state of the ground on which the retaining wall structure is constructed, the state of the second retaining wall, and the like, the straight strip 300 may be connected / coupled only to some coupling members, not all coupling members.

On the other hand, as shown in Figure 15, it will also be possible that the straight strip 300 is connected / coupled to each of the coupling members.

16 and 17 are views showing the coupling between the coupling member and the straight strip according to another embodiment of the present invention.

As in the case of Figure 16, the engaging member 20 of the embodiment does not have a straight fastening hole is formed in the coupling member, unlike the case of Figure 12, the engaging bar 22 in the coupling hole 22 so that the coupling guide member is fitted to the coupling member 50 may be formed. In this case, the straight strip 300 positioned in the reinforcement soil (field soil, etc.) of the second retaining wall is connected to the engaging bar 50, thereby making a connection between the straight strip 300 and the coupling member.

On the other hand, even when a separate configuration such as the strip fastening hole 40 of FIG. 12 or the locking bar 50 of FIG. 16 is not formed in the coupling member, the straight strip 300 may be coupled. That is, as shown in Figure 17, in the case of the coupling member formed with a coupling hole 22 for engaging with a separate member such as a coupling guide member, the straight strip 300 passes through a portion 26a of the body Since it can be connected, it is also possible to use it via a part of the coupling member body.

18 is a view showing the configuration of a connecting member that can combine the all-around strip according to the present embodiment, Figure 19 shows a straight strip surrounding the periphery, such as tonang and field soil as a construction unit according to this embodiment The figure showing.

According to the present embodiment, the all-around strip 200 combines the sack of the first retaining wall and the field soil of the second retaining wall through the coupling member 20. In particular, the all-around strip 200 may include a plurality of coupling members. Via (20), it is configured to surround the entire circumference of the first retaining wall and the second retaining wall, thereby inducing the entire engagement of the first retaining wall and the second retaining wall.

The all-around strip 200 may be made of a synthetic resin, by stacking the construction unit and the site soil in the field to pass the all-around strip 200 through a plurality of connecting members, the combination can be made.

The coupling member 20 of the embodiment includes a body 26 forming a body, a plurality of coupling protrusions 24 protruding from one surface of the body 26 to be inserted into the tonang, which is a construction unit, and the body. A strip passing portion 60 is formed on the other surface of the 26 to allow the all-around strip 200 to pass therethrough.

The strip passing portion 60 is configured to protrude from the other surface of the coupling member 20 body, and the all-round strip 200 passes through the hole made by the strip passing portion 60. By the all-round strip 200 passing through the strip passing portion 60 formed in each coupling member 20, a plurality of coupling members 20 are bound to the all-round strip 200, the all-round strip ( 200 is disposed to surround the second retaining wall behind the construction unit, which is the first retaining wall. Through this configuration, the first retaining wall and the second retaining wall are bound in a structure different from that of the straight strip 300. Since the binding is performed along the entire circumference of the retaining wall structure, the construction of the rigid retaining wall structure is possible.

20 is a view illustrating a state in which the all-around strip is coupled using the coupling member shown in FIG. 17.

That is, as in the case of Figure 17, even if the hole 22 is formed in the coupling member body 26, there is no separate configuration for coupling the all-around strip or straight strip, the first retaining wall and the second retaining wall as a whole When the all-around strip 200 disposed to surround the periphery is disposed to pass through the hole 22 from the front of the coupling member 20 to the rear, the first retaining wall and the first retaining wall 200 are to be achieved.
