Description

Reinforced soil wall structure and construction method

The present invention relates to a reinforced soil retaining wall structure and a construction method thereof, and more particularly, to a reinforced soil retaining wall structure and a method of constructing a block or panel forming a skin of a reinforced soil retaining wall to be connected in a horizontal direction. .

The slopes generated by cutting or embankment form skins of reinforced soil retaining walls with blocks or panels to prevent safety accidents due to the loss and collapse of soil and improve the landscape. In addition, the backfilling soil filled in the rear of the retaining wall has a reinforcement so that one end of the reinforcement is connected to a block or panel forming a skin. Geogrid may be used as the reinforcing material, and recently, a band-shaped reinforcing material is used.

The band reinforcement is band-shaped and is made of a somewhat flexible synthetic resin material, which may be constructed with high strength polyester fibers or polyethylene sheaths thereon. Such a band-shaped reinforcement should be installed horizontally in the backfilling soil to maximize the frictional force with the backfilling soil to firmly fix the block or panel forming the skin of the reinforcing soil wall.

Conventionally, in order to connect the band-shaped reinforcement with a block or a panel, an installation groove is placed in the block or panel, and the band-shaped reinforcement is hooked around the guide rod by walking on the installation groove or by placing a guide rod in the block or panel. This is well disclosed in Korean Patent Publication No. 10-2018-0066926 in the following prior art document.

However, the installation groove is formed to open on the top or rear end of the block or panel is a form that the belt-shaped reinforcement is seated from the top. Therefore, when the backfill soil is stabilized and the position of the band reinforcement is changed, there is a problem that the band reinforcement is easily dropped from the installation groove and the fixing to the block or the panel is damaged.

In addition, when the belt-shaped reinforcement is placed in the installation groove to be hooked to the block or panel, there is a problem that a portion of the belt-shaped reinforcement is not maintained in a horizontal state, the friction force is not properly made between the back-filled soil in the corresponding portion.

And, around the band-shaped reinforcement with the guide rods, in practice, when the band-shaped reinforcement is folded and connected to the block or panel, the guide rod is used at the time of construction, so the number of parts increases and the work of wrapping the band-shaped reinforcement to surround the guide rod is required. There is a problem in that the construction is not easy.

In addition, in the prior art, since a band-shaped reinforcement is located on the same layer in the backfill soil, as described above, the relative position between the band-shaped reinforcement and the block or panel is easy to change, and the damage of the band-shaped reinforcement itself is prevented by folding the band-shaped reinforcement. There is a problem that is easy to occur.

And, when constructing the reinforced earth retaining wall, in the existing method of connecting the band-shaped reinforcement in the horizontal (horizontal) direction from the earthwork surface, such as fixed reinforcing bars and fixing reinforcing bars or fixing pins for connecting and installing the zigzag on the back side of the retaining wall Subsidiary materials should be used and some rigid band-shaped reinforcements should be folded completely and installed. In particular, the belt-shaped reinforcement has some stiffness, so it is very difficult and inconvenient to construct it to be folded at 180 degrees, and if it is folded rapidly, damage to the band-shaped reinforcement may occur.

In adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used to refer to the same components as much as possible, even if displayed on different drawings. In addition, in describing an embodiment of the present invention, if it is determined that the detailed description of the related well-known configuration or function interferes with the understanding of the embodiment of the present invention, the detailed description thereof will be omitted.

In addition, in explaining the component of the Example of this invention, the terms, such as 1st, 2nd, A, B, (a), (b), can be used. These terms are only for distinguishing the components from other components, and the nature, order or order of the components are not limited by the terms. If a component is described as being "connected", "coupled" or "connected" to another component, that component may be directly connected or connected to that other component, but there is another component between each component. It will be understood that may be "connected", "coupled" or "connected".

As shown in the drawings, the reinforced earth retaining wall structure according to the embodiment of the present invention is installed with a block 20 stacked in a plurality of layers on the ground 10, the band-shaped reinforcement 30 directly connected to the block 20 Is positioned horizontally in the backfill soil 40 behind the block 20 over several layers.

In the illustrated embodiment, the band reinforcing material 30 is to pass through the two blocks 20 are stacked at the same time, but is not necessarily so, it may pass through only one block 20. In the embodiment illustrated in FIG. 1, two stacked blocks 20 are formed to form one block layer. However, one block 20 may be formed to form one block layer.

And, as can be seen in FIG. 1, one in the lower layer and one in the upper layer are staggered from each other so that one block of the upper layer is on two adjacent blocks 20 of the lower layer. 20 is seated. By stacking the blocks 20 in this manner, the skin of the reinforced soil retaining wall formed by the block 20 is firm.

Here, the configuration of the block 20 will be described in detail with reference to FIGS. 4 and 5. The block body 21 forms the skeleton of the block 20. The front plate 22 forms a front portion of the block body 21. The front plate 22 forms the front surface of the reinforcing soil wall. At both ends of the front plate 22, a plurality of valleys are sequentially formed to be inclined backward. The rear plate 22 ′ forms a rear portion of the block body 21. The width of the back plate 22 ′ is smaller than the width of the front plate 22. Both ends of the front plate 22 have concavities and convexities (not shown) corresponding to each other so that the concave and convex portions of adjacent blocks 20 may be coupled to each other.

A portion of the block body 21 connecting the front plate 22 and the rear plate 22 ′ has an approximately H shape in cross section, but the shape of the block body 21 may be variously made. . The through hole 23 is formed by penetrating the block body 21 up and down. The strip-shaped reinforcement 30 penetrates the through hole 23.

On the upper surface of the block body 21, there are two tip projections 25. The tip protrusion 25 is formed to protrude to the rear adjacent to the front plate (22). Two rear end projections 26 protrude from the upper end of the block body 21, that is, the position adjacent to the rear plate 22 ′.

A front end channel 25 ′ and a rear end channel 26 ′ are formed on the bottom surface of the block body 21 to correspond to the front end protrusion 25 and the rear end protrusion 26. In the front end channel 25 'and the rear end channel 26', the front end projection 25 and the rear end projection 26 of the block which are relatively lower are located. The front end channel 25 'and the rear end channel 26' are formed to transversely cross the lower surface of the block body 21.

Meanwhile, a reinforcing material passage 28 is formed in the rear plate 22 ′ of the upper surface of the block body 21. The reinforcing material passage 28 is made by removing a part of the back plate 22 'so that the band-shaped reinforcing material 30 can pass between the block bodies 21 stacked up and down, thereby allowing the band-shaped reinforcing material 30 and the block to pass therethrough. The body 21 does not interfere.

A partition hook end 29 is formed through the center of the through hole 23 so as to divide the through hole 23 into two regions. The partition hanger 29 extends from both sides of the inner surface of the through hole 23 so that the two face each other. The band-shaped reinforcing material 30 penetrating the through hole 23 is hooked to the partition hook end 29. Of course, the band-shaped reinforcing material 30 may be hooked to the back plate 22 ′ in the through hole 23. However, if the band-shaped reinforcement 30 is hooked to the partition hook end 29, even if the unintentional large force acts between the block 20 and the band-shaped reinforcement 30, even if the partition hook stage 29 is broken back Since the strip 22 is caught by the plate 22 ′, the block 20 is no longer moved, thereby minimizing damage to the reinforcing soil retaining wall.

The band reinforcing material 30 is made of a band shape having a predetermined width and thickness, basically made of a flexible material. The band reinforcing material 30 is made of a synthetic resin material, for example, may be made of a polymer material, and may be made of a high strength polyester fiber or a polyethylene coating added thereto. This strip-shaped reinforcement 30 is extended in one direction to provide a friction force between the backfill soil in the backfill soil (40). In this embodiment, the band-shaped reinforcement 30 is connected to the block 20 by penetrating the block 20 up and down, and the extension direction is changed based on the block 20. In addition, the portion of the strip-shaped reinforcement 30 and the portion of the strip-shaped reinforcement 30 emerged to the upper side relative to the through hole 23 of the block 20 is located in different layers in the backfill soil.

For reference, the specific configuration of the strip-shaped reinforcing material 30 is as follows. The strip-shaped reinforcing material 30 is composed of a strip base made of the material described above and a resistance protrusion integrally formed on the surface of the strip base. Such a band-shaped reinforcing material 30 is flexible in nature of the material, but can be folded to a certain degree or more force to be folded and should be folded by applying a considerable force so that the adjacent parts overlap each other.

Next, another embodiment of the present invention will be described with reference to FIGS. 7 to 10. For convenience of description, the reference numerals of the other components except for the reference numerals of the panel 120 used instead of the block 20 use the same reference numerals as the above embodiment.

In the present embodiment, unlike the block 20 of the above embodiment, the skin 120 of the reinforcing soil retaining wall is the panel 120. Panel 120 is a panel body 121 of the rectangular plate shape forms a skeleton. The panel body 121 has a predetermined thickness in the front-rear direction, except for the coupling end 124 which will be described below, and has a substantially rectangular plate shape. The thickness of the panel body 121 is relatively thinner than the corresponding thickness of the block 20.

An upper coupling recess 122 is formed along an upper end of the panel body 121, and a lower coupling recess 122 ′ is formed along a lower end of the panel body 121. The upper coupling recesses 122 are relatively protruded from the front side of the panel body 121, and the lower coupling recesses 122 'are relatively protruded from the rear side of the panel body 121. Therefore, when the panel 120 is stacked, the upper coupling unevenness 122 of the panel 120 in the lower portion and the lower coupling unevenness 122 'of the panel 120 in the upper portion are fitted to each other and the panel body 121 Relative movement in the front-rear direction is prevented.

Side coupling recesses 123 are formed at upper and lower sides of the panel body 121, respectively. The side coupling concave-convex 123 is made so that the front side of the panel body 121 is relatively protruded.

A coupling end 124 protrudes from the side of the panel body 121. The coupling end 124 extends in the upper and lower directions starting from the middle portion of the side surface of the panel body 121 and occupies approximately half of the side surface of the panel body 121. The coupling hole 125 is formed by penetrating the coupling end 124 up and down. The coupling hole 125 may be inserted into the coupling hole 125 of the other side panel 120 to which a separate coupling rod is installed and coupled.

Single coupling unevenness 126 is formed on the outer surface of the coupling end 124, and the single coupling unevenness 126 is formed in a shape corresponding to the side coupling unevenness 123. The side coupling recesses 123 and the single coupling recesses 126 of the adjacent panel 120 are coupled to each other.

A through path 127 is formed in the panel body 121. The through path 127 is formed in a curved shape having a predetermined curvature, both ends of which are open to the rear surface of the panel body 121. The configuration of the through path 127 is well illustrated in FIG. 10. The band-shaped reinforcing material 30 can easily penetrate the inside by the through path 127 is a curve having a predetermined curvature. There are two entrance and exit ports 128 through which the through paths 127 are opened to the rear surface of the panel body 121. Therefore, the band-shaped reinforcing material 30 enters the through path 127 through one of the entrance and exit ports 128 and exits through the other entrance and exit 128.

The through-path 127 is formed in a plurality of the panel body 121, the height of the entry and exit port 128 is formed to match those of the adjacent through-path 127. This is to make the fill work of the backfill soil 40 by a certain thickness.

Among the through paths 127, those formed adjacent to the top and bottom of the panel body 121 are made to have a length that is half of that of the other through paths 127. Therefore, the through-path 127 formed adjacent to the upper and lower ends of the panel body 121 has an intermediate outlet 128 'to be opened to the upper and lower surfaces of the panel body 121. The intermediate outlet 128 ′ allows the corresponding intermediate outlet 128 ′ of the panel 120 stacked up and down to be connected to each other to form one through path 127. The panel 120 stacked up and down by the through-path 127 having the intermediate outlet 128 ′ is connected to each other by the band-shaped reinforcement 30.

In the panel body 121, a reinforcing material passage (not shown) is formed at the position where the intermediate outlet 128 'is formed so that the band-shaped reinforcing material 30 can pass between the panels 120 stacked up and down without interference. good. For reference, in FIG. 10, a through path 127 that is not within the cutting line is indicated by a dotted line.

In the case where the panel 120 forms the skin of the reinforcing soil wall as in the present embodiment, the other components except for the panel 120 are the same in the reinforcing soil wall.

Hereinafter will be described in detail the construction process of the reinforced soil retaining wall according to the present invention having the configuration as described above. For convenience, only the case in which the block 20 is used as a skin of the reinforced soil retaining wall will be described with reference to FIG. 6.

Penetrate from bottom to top. In this embodiment, the blocks 20 are stacked two by one, but may be stacked one by one as described above. The remaining portion of the strip-shaped reinforcement 30 which has passed through the through-holes 23 of the two blocks 20 is flipped toward the front of the block 20 as shown in the drawing. In this state, fill the backfill soil (40) to perform the fill work.

Here, the strip-shaped reinforcement is cut to a predetermined length, twice the length from the rear end of the back-filling soil 40 to the block 20 and the length of the portion located in the through hole 23 of the block 20 Is cut to the combined length.

6 (a) shows a state in which the fill work for the backfilling soil 40 as high as two blocks 20 stacked on the ground 10 for the first time is completed. In this state, the belt-shaped reinforcing material 30 that has been rolled toward the front of the block 20 is placed on the upper surface of the backfilling soil 40. This state is shown in Fig. 6B. For reference, the blocks 20 are arranged in two stacked rows to cover the entire area where the reinforcing soil walls are formed.

Next, the two blocks 20 are stacked again on the two stacked blocks 20. At this time, the block 20 in the lower part and the block 20 in the upper part are not matched with each other without being stacked, so that the block 20 in the upper part is simultaneously seated on the two blocks 20 in the lower part. That is, as shown in FIG. 1, the blocks 20 stacked in two layers are alternately arranged with the blocks 20 in the lower layer as shown in FIG. 1. do.

Of course, a new strip-shaped reinforcing material 30 is laid on the upper surface of the backfilling soil 40 of FIG. 6A to penetrate the through-holes 23 of the two blocks 20 and penetrate the two blocks 20. Leave the rest of the strip-shaped reinforcement 30 to the front of the block 20. This state is shown in Fig. 6C.

Next, the backfilled soil 40 is filled in the rear of the second two stacked blocks 20, and the filling work is performed, and when the filling work is completed, the front of the block 20 on the upper surface of the backfilling soil 40 is completed. Position the rest of the strip-shaped reinforcement (30) that was turned over. This state is well illustrated in FIG.

Repetitive work in the manner described above can create a reinforcement earth retaining wall of the desired height.

In addition, when the panel 120 is used, the strip-shaped reinforcing material 30 does not penetrate the panel 120 vertically, but passes through the inside of the panel body 121 through the rear surface of the panel body 121 and again the panel body. It is to come out to the rear of the 121, both entrance and exit ports 128 of the through-path 127 made for this is open to the rear of the panel body 121 and the through-path 127 is a curve having a predetermined curvature It is.

Therefore, the band-shaped reinforcing material 30 passing through the panel 120 is not suddenly folded, and the band-shaped reinforcing material 30 positioned inside the back filling soil 40 is horizontally positioned in the entire area in different layers so that the back filling soil ( Friction with 40 can be maximized.
