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 block 2, the front and rear reinforcement 3 is modified, or the fixing method for the block 2, the reinforcement soil 4 and the rear soil 1 of the front and rear reinforcement 3 is modified or constructed. It is to install a lateral reinforcement (not shown) to prevent deformation of the block 2 structure.

However, in the conventional reinforcement earth retaining wall having a structure reinforced by the front and rear reinforcement 3 and the left and right reinforcement in this way, it is possible to reliably prevent deformation of the block 2 structure constructed against harmful external force, in particular, earthquake. Since no means have been developed, it has been pointed out as a problem.

That is, the above-described conventional structure of the block 2, the forward and backward reinforcement 3, and the anchor can not expect any buffering action against the longitudinal load caused by the earthquake. When seismic loads exceed the design load, the retaining wall structure had to surrender as it was.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a seismic wall structure that can be sufficiently resisted by a buffering action even when a longitudinal load is applied by an earthquake.

The present invention, in order to achieve the object as described above, a plurality of surface material 100 is built on the front of the rear soil (4), the support groove 110 is formed; It includes a left and right reinforcement portion 201 and the front and rear reinforcement portion 202, the front end is inserted into the support groove 110 so as to support the surface material 100 to the rear, the rear end is the rear soil (4) or And a reinforcement member 200 installed to be supported by the anchor, wherein the support groove 110 is formed to have a curved structure at the bottom thereof, and the inner width and depth of the support groove 110 are the reinforcement member 200. It proposes a seismic wall structure that allows local vibration, characterized in that larger than the diameter of.

The outer circumference of the reinforcement 200 is preferably covered by the rolling pipe 210 to protect the reinforcement 200 by rolling when the reinforcement 200 is driven in the support groove 110.

The rolling pipe 210 is preferably formed of an elastic material.

The rolling pipe 210 is preferably coupled to the left and right reinforcement portion 201.

The rolling pipe 210 is preferably coupled to the front and rear reinforcement portion 202.

The support groove 110 of the surface material 100 includes a 'T' shaped structure, the front end of the reinforcement 200 is a 'T' shaped, 'a' shaped or 'c' shaped structure desirable.

Protrusions 101 and recesses 102 are formed on the top and bottom surfaces of the surface material 100, respectively, and the inner width of the recesses 102 may be larger than the outer width of the protrusions 101.

Preferably, the protrusions 101 and the recesses 102 have a trapezoidal cross-sectional shape.

It is preferable that a buffer unit 120 is formed on the top or bottom of the surface material 100 to cushion the impact with the adjacent surface material 100.

The buffer unit 120 is preferably formed by the application of a buffer.

The buffer unit 120 preferably includes an elastic pad 121 coupled to the top or bottom surface of the surface material 100.

The present invention proposes a seismic wall structure that can be sufficiently resisted by a buffering action even when a longitudinal load is applied by an earthquake.

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

2, the earthquake-resistant wall structure according to the present invention is basically, a plurality of surface material 100 is built on the front surface of the rear soil 4, the support groove 110 is formed; A front end is inserted into the support groove 110 so as to support the surface member 100 rearward, and the rear end is supported by the rearing soil 4 or the anchor so as to support the surface member 100 rearward. Installed reinforcement 200; is configured to include.

Here, the support groove 110 of the surface material 100 is formed so that the bottom surface has a curved structure (for example, 'U' shaped cross-sectional structure), and the inner width and depth of the support groove 110 is the reinforcing member 200 It is characterized by being larger than its diameter.

That is, as shown in Figure 4, when the longitudinal load is applied by the earthquake, since the reinforcement 200 can vibrate to some extent inside the support groove 110 having a large width and depth, a number of such structures are stacked As a result, elastic behavior becomes possible as a whole.

In the case of the conventional wall structure, when the seismic load is applied to the earth pressure of the back ground sediment, when forced to surrender as it is, the wall structure according to the present invention has a certain degree of cushioning action due to the above elastic behavior. Even if an earthquake load is applied, the retaining wall structure does not yield.

In addition, even if the destruction of the structure cannot be avoided by a very large earthquake load, due to the above shock absorbing action, it is possible to avoid the sudden destruction of the structure (brittle failure), so that the people around can have enough time to evacuate. It has the advantage of being (ductile fracture).

Hereinafter, specific examples of the structure of the wall structure according to the present invention will be described.

When the reinforcement 200 is driven in the support groove 110 of the surface material 100, damage may occur to the surface material 100 or the reinforcement 200 by friction between the outer surface of the reinforcement 200 and the inner surface of the support groove 110. Can be.

In order to prevent this, as shown in FIG. 5, it is preferable that the outer circumference of the reinforcement 200 is covered by the rolling pipe 210 so as to protect the reinforcement 200 by rolling.

As shown in FIG. 6, when the reinforcement 200 is driven in the support member 110, the surface member 100 is driven together with the reinforcement 200 while rolling, such as the surface member 100 or the reinforcement 200 as described above. ) Can effectively prevent damage.

In addition, when the rolling pipe 210 is formed of an elastic material, it is possible to buffer by the elastic force and the elastic restoring force itself, it can further contribute to the elastic behavior of the retaining wall structure.

2 or less, the support groove 110 of the surface material 100 shows a 'T' shaped structure, the front end of the reinforcement 200 is a 'b' shaped structure as shown, The front end of the reinforcement 200 may take a 'T' shape or a 'c' shape or the like.

Rolling pipe 210 is coupled to the left and right reinforcement portion 201 of the reinforcing material 200 is inserted into the support groove 110 of the surface material 100, it is possible to sufficiently perform the above operation, furthermore rolling pipe 210 ) Is coupled to the front and rear reinforcement portion 202 of the reinforcement 200, it is added that the elasticity can also be given to the left and right behavior of the surface material 100 or the reinforcement 200.

As shown in FIG. 7, the protrusions 101 and the recesses 102 are formed on the top and bottom surfaces of the surface material 100, respectively, and the inner width of the recesses 102 is larger than the outer width of the protrusions 101. In this case, the buffering effect as described above can be obtained due to the clearance between the protrusion 101 and the recess 102.

For this purpose, it is preferable that the protrusions 101 and the recesses 102 have a trapezoidal cross-sectional shape.

As shown in FIG. 8, it is preferable that a shock absorbing part 120 is formed on the top or bottom of the surface material 100 to cushion the impact with the adjacent surface material 100. This results in the following effects. .

First, since the shock absorbing effect against the vertical impact, it is possible to prevent damage and destruction of the retaining wall thereby.

Secondly, mutual longitudinal driving is constrained by the frictional force between the cushioning portion 120 and the surface of the surface material 100 in surface contact therewith, but in the event of a large longitudinal load such as an earthquake, the mutual longitudinal driving to some extent occurs. By permitting this, it is possible to prevent sudden destruction (brittle failure) of the entire retaining wall structure.

The buffer unit 120 may be formed by applying a buffer, or may be formed by bonding the elastic pad 121 made of a rubber material or the like to the top or bottom surface of the surface material 100.
