The present invention relates to a reinforced soil retaining wall, and more particularly, to a method for installing a retaining wall of a more stable and rigid structure against earthquakes and other harmful external forces using surface materials and reinforced soil and reinforcing materials.

22 is a cross-sectional view showing the structure of a conventional reinforced earth retaining wall.

As shown, the conventional reinforcement earth retaining wall has a plurality of surface material blocks (2) are constructed with a predetermined space from the rear soil (1), and the front and rear directions in which the rear end is fixed to the rear soil (1) or anchor (not shown) The front end of the reinforcing material 3 is fixed to the surface material block 2, and the reinforcing soil 4 is filled and compacted in the space between the rearing soil 1 and the surface material block 2, whereby the surface material block 2 collapses. Takes a structure to prevent.

Here, the front and rear reinforcement (3) serves as a tension member connecting the surface material structure and the rearing soil, a rigid reinforcement such as reinforcing bar may be used, or a flexible reinforcement such as geogrid (mesh).

Since the reinforced earth retaining wall is evaluated as having excellent economic and mechanical stability compared to the concrete gravity retaining wall, it is being constructed by various modifications.

For example, the structure of the surface material block (2), the front and rear reinforcement (3) is modified, or the fixing method for the surface material block (2), the reinforcement soil (4), the rear soil (1) of the front and rear reinforcement (3) or In order to prevent deformation of the structured surface material block 2 structure, such as installing a left and right reinforcement (not shown).

Rigid reinforcement such as reinforcing bar may be used for the front and rear reinforcement 3, or a flexible reinforcement such as geogrid, mesh or the like may be used.

Among them, it is more advantageous to use a ductile reinforcement for the front and rear reinforcement 3 of the reinforcing soil retaining wall, for the following reason.

First, since the front and rear reinforcement (3) in the retaining soil retaining wall can be said to be a kind of tension member that is supported by the rear soil (1) to prevent the overturning of the surface material structure, it is formed by a soft material than formed by a brittle material It is more advantageous mechanically.

Second, when the reinforcement soil retaining wall is installed, the front and rear reinforcement 3 is supported between the rear end portion of the reinforcement soil 4, which is filled and compacted behind the surface material structure, and is also supported by the frictional force with the soil body. In order to increase the frictional force, the larger the contact area of both structures is, the more advantageous it is, and thus, a soft reinforcement such as a geogrid and a mesh may be advantageous compared to a rigid reinforcement such as a rebar.

Third, when a relative displacement occurs between the surface material structure, the reinforcement soils and the back soils due to earthquakes, ground subsidence, etc., a relative displacement occurs between the surface material structure and the front and rear reinforcement materials. There is a problem in that breakage is likely to occur at the contact portion of the front and rear reinforcement.

On the other hand, in order to ensure the structural stability of the reinforcement earth retaining wall, not only the material and structure of each of the surface material structure and the front and rear reinforcement should be excellent, but also the stable settlement of the surface material structure and the front and rear reinforcement must be premised.

However, in the conventional reinforcement earth retaining wall, when a flexible reinforcement is used as the front and rear reinforcement (3), no structure for stable fixing with the surface material structure has been developed. It has been pointed out as a problem because it was common to use it as a kind of forward and backward reinforcement 3.

In other words, the ductile stiffener is excellent in terms of tensile resistance, bearing capacity by the reinforcement soil, and the possibility of fracture due to ground subsidence, as described above, and thus is more suitable for use as the front and rear reinforcement (3) of the retaining soil retaining wall than the stiffening stiffener. Despite the material, due to the above problems was a fact that the frequency of use is low, the development of a stable fixing structure of the surface material structure and the flexible reinforcement can be said to have been urgently requested in the art.

The present invention has been made in order to solve the above problems, so that the flexible reinforcement that can exert a superior performance compared to the rigid reinforcement in the reinforced soil retaining wall can be applied as a front and rear reinforcement as a tension member, stable surface material structure and flexible reinforcement It is an object of the present invention to propose a reinforcement earth retaining wall having a structure capable of fixing.
