Description

Gusset retaining wall {EARTH RETAINING WALL}

The present invention relates to a retaining wall, and more particularly, to a reinforcement earth retaining wall using a wire mat formed of a wire rod.

Soil is generally not strongly adhered to the particles, unlike materials such as rock, steel and concrete. Therefore, the soil itself has a limit in exerting a predetermined strength. However, when a large number of strip-shaped reinforcement materials are placed in the soil at appropriate intervals, the adhesion of the soil is greatly increased. In this way, the soil with the adhesive strength is called reinforcement soil. Reinforced soil retaining wall is a retaining wall formed by such a reinforced soil. In order to form a reinforcement earth retaining wall, conventionally, a reinforcement earth retaining wall composed of a wall material of a block or concrete panel material, a reinforcing material connected to the wall material, and a fill material filled on the reinforcing material was mainly used. In the case of the conventional reinforcement earth retaining wall is a cumbersome work because it must be connected between the wall material and the reinforcement provided separately. In addition, since a block or concrete panel is used as the wall material, vegetation is impossible on the wall. On the other hand, in US Patent Nos. 4,117,686 and 4,505,621, the wire mat is formed integrally with the wall material and reinforcing material, but the vegetation is difficult as in the prior art because the wall surface is filled with stone.

It is an object of the present invention to provide a retaining wall in which a wall member and a reinforcement are integrally formed and a method of forming the retaining wall. Another object of the present invention is to provide a retaining wall which is easier to work with and a method of forming the retaining wall. It is still another object of the present invention to provide a reinforcement earth retaining wall and a method of forming a retaining earth retaining wall capable of vegetation on a wall surface.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1 is a cross-sectional view of a reinforced soil retaining wall according to a first embodiment of the present invention. Referring to FIG. 1, the reinforcement soil retaining wall 10 includes first and second wire mesh mats 20 and 20a stacked in three layers on the basic crushed stone 200, the upper mat 80, and the auxiliary mat. A mat 30, a net member 40, a vegetation mat 50, and a fill material 15 are provided. 1 to 3, in the exemplary embodiment of the present invention, the first wire mat 20 forming the first layer and the second layer among the wire mats stacked in three layers has a plurality of transverse roots 22 and longitudinal roots 24. ) Are combined to form a lattice shape. In the present embodiment, the transverse bar 22 and the longitudinal bar 24 are galvanized steel bars, but the present invention is not limited thereto. The first wire mat 20 has a bottom portion 26 which extends flat in the horizontal direction, and a plurality of longitudinal roots 24 are bent upward from the bottom portion 26 about one transverse root 221. A wall surface portion 28 is provided. The wall portion 28 may be bent to form a desired angle at 90 degrees or less with the bottom portion 26 as shown in FIG. In the present embodiment, the bottom portion 26 and the wall surface portion 28 assume an angle slightly smaller than 90 degrees. The bottom portion 26 extends relatively longer than the wall portion 28. The bottom portion 26 interacts with the fill material 15 to help the fill material 15 maintain its position more stable. The longitudinal muscle 24 extends longer than the transverse muscle 222 provided on the top of the wall portion 28. The longitudinal muscles 24 extending above the top transverse muscles 222 extend slightly forwardly (opposite to the bottom 26) and back slightly laterally towards the rear (bottom 26) and then the original extension. Bend in the direction. In this way, the engaging portion 29 is formed in the upper portion of the wall surface portion 28 is formed by a plurality of longitudinal muscles 24 protrude forward. Transverse roots 221 between the bottom portion 26 or 26a of the first wire mat 20 or the second wire mat 20a and the wall surface 28 or 28a placed on the lower outer side of the locking portion 29. Or 221a). As shown in (a) of FIG. 2, a plurality of such first wire mats 20 are disposed to extend side by side in each layer.

1 and 2, a plurality of auxiliary mats 30 are continuously coupled to the rear side of the wall portion 28 of the first wire mat 20. Although not shown, the auxiliary mat 30 may be coupled to the wall portion 28 of the first wire mat 20 by a material such as wire. The auxiliary mat 30 is formed by combining a plurality of transverse roots 32 and longitudinal roots 34 in a lattice shape. The eye of the auxiliary mat 30 is smaller than the eye of the first wire mat 20. The height of the auxiliary mat 30 is at the top at the top of the wall surface 28 of the first wire mat 20 when the auxiliary mat 30 is coupled to the rear side of the wall portion 28 of the first wire mat 20. The degree of contact with the transverse muscle 222 is located. 1 and 2 (b), the transverse roots 32 and the longitudinal roots 34 of the auxiliary mat 30 are transverse roots 22 of the wall portion 28 of the first wire mat 20, respectively. ) And the longitudinal root (23). Referring to FIG. 2 (b), when two auxiliary mats 30 coupled to the rear side of the wall portion 28 of the first wire mat 20 are successively coupled, the longitudinal root of one end mat 30 is joined. 341, the longitudinal longitudinal roots 341 of the other auxiliary mat 30 are directly overlapped so as to be positioned (see FIG. 2 (b), which is seen from above).

Referring to FIG. 2A, not all of the auxiliary mats 30a positioned at the beginning or the end of the plurality of auxiliary mats are coupled to the wall portion 28 of the first wire mat 20, but some of them are not. Coupled to the wall portion 28 and the remaining portion is bent backward as shown, the lower portion is in contact with the bottom portion 26 of the first wire mat (20). A portion of the auxiliary mat 30a, which is bent and extended backward, is shown by a dotted line, so that the bottom portion 26 and the wall portion 28 of the first wire mat 20 form an angle smaller than 90 degrees. 26) Go down. This part, shown by the dotted line, is cut out.

Referring to Figure 1, the mesh member 40 is coupled behind the auxiliary mat (30). Although not shown in detail, the mesh member 40 has smaller eyes than the auxiliary mat 30. In this embodiment, the net member is used by the continuous molding of high-density polyethylene, but the present invention is not limited thereto. The net member 40 may be connected to the auxiliary mat 30 or the wall surface 28 of the first wire mat 20 by a material such as wire. Behind the net member 40 is a vegetation mat 50 is coupled. Vegetation mat 50 may also be combined in the same manner as the net member (40). Vegetation mat 50 is installed so that the plant toward the wall portion 28 of the auxiliary mat (30). Vegetation mat 50 may be installed after the plant is grown to some extent.

When constructing the retaining wall, as shown in Figure 1, filling the ground material 15 to the back of the vegetation mat (50) to form a first floor. Soil is used as the fill material 15, but the present invention is not limited thereto. In another embodiment, a stone such as amber or crushed stone may be used as the fill material 15. In order to form two layers, the first wire mat 20 is placed on one layer. At this time, the transverse root 221 between the bottom portion 26 and the wall surface portion 28 of the first wire mat 20 on the second floor is lower than the locking portion 29 of the first wire mat 20 on the first floor. It is placed outside and caught. Hereinafter, two layers are formed by the same method and structure which form one layer.

Through the above configuration, frictional force is generated between the longitudinal roots 24 and 24a of the bottom parts 26 and 26a of the first and second wire mats 20 and 20a and the fill material 15. In addition, acupressure resistance is generated between the transverse roots 22 and 22a of the bottom portions 26 and 26a of the first and second wire mats 20 and 20a and the landfill material 15. Due to such friction and acupressure resistance, the fill material is stabilized. The vegetation mat 50 is greened on the wall to improve aesthetics.
