The present invention relates to a reinforcement soil retaining wall and a method of installation, and more particularly, to a method for installing a retaining wall of a more stable and robust structure against earthquakes and other harmful external forces by using a block and reinforcement soil and a reinforcing member.

20 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 portion of the reinforcing member 3 is fixed to the surface material block 2, and the reinforcement 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 It is structured to prevent collapse.

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

It has been pointed out as a problem because no means to prevent it have been developed.

That is, even if the protrusions and recesses are formed on the upper and lower surfaces of the surface material block 2, respectively, and the deformation of the structure of the surface material block 2 is prevented by the combination of the protrusions and the recesses, the surface material block 2 is basically a concrete or brittle. Since it is formed of a material, even if a small stress concentration is applied, the protrusion easily breaks, and thus, a problem has been raised that it is difficult to obtain the required strength.

Further, in the construction and compaction of the surface material of each layer of the reinforced soil retaining wall, longitudinal and lateral loads are applied by vibration of the compaction equipment, which causes initial cracking and decreases the strength of the structure. As a result, it is more adversely affecting the strength of the structure than the ex post load such as an earthquake.

Third, as shown in Figures 5 and 6, the surface block 100 is a vertical reinforcement member on both sides so that the secondary up and down reinforcing member insertion hole is formed by contact with the surface material block 100 is installed on the side Insertion groove 140 is further provided, the insertion hole is formed by the up and down reinforcement member insertion hole 120 and the secondary up and down reinforcement member insertion hole of the surface material block 100 of the plurality of surface material block 100 is constructed It may take a structure to be formed.

That is, the insertion grooves 140 are formed on both sides of the surface material block 100 so as to form secondary up and down reinforcing member insertion holes upon contact with the surface material block 100 to be installed adjacent to each other. By forming the insertion hole to meet the insertion hole of the surface material block 100 it is possible to form a zigzag structure.

The left and right reinforcement member 200, the up and down reinforcement member 210, and the front and rear reinforcement member 220 is generally formed by reinforcing bars, but also by materials such as steel wire, stranded wire, iron wire, plastic, reinforced plastic, and wire. It may be formed, it may be used a separate material according to the characteristics of each reinforcing member.

In addition, the left and right reinforcement member 200, the up and down reinforcement member 210, the front and rear reinforcement member 220 may have a straight structure, or may take a spiral twist structure made of steel or stranded wire material, pipe structure It does not matter if we take.

Here, when the vertical reinforcement member 210 is a vertical reinforcement pipe 210a having a pipe structure, as shown in FIG. 8, the through hole 212 of the front and rear reinforcement member 210 is formed in the core portion. In addition, the through holes 213 of the left and right reinforcing members 200 are formed at both sides of the through holes 212, so that the front and rear reinforcing members 220 are left and right in the inner space of the up and down reinforcing pipes 210a. The direction reinforcement member 200 may have a structure that is mutually fixed by the reinforcement member connecting means 300.

In the reinforcement earth retaining wall according to the present invention, the component corresponding to the largest technical feature may be referred to as a vertical reinforcement member 210. In order to obtain a more stable and robust structure, the vertical reinforcement member 210 and the surface material block ( The settlement between 100 should be stable and solid.

Therefore, it is preferable to take the structure further provided with a gap filling means 600 for filling the gap between the up and down reinforcement member 210 and the up and down reinforcement member insertion hole 120, such a gap filling means 600 ) May be implemented by various embodiments as follows.

First, in the state where the vertical reinforcing member 210 is inserted into the insertion hole 120, it is possible to fill the gap by pouring and curing epoxy, mortar, concrete or other liquid material in the insertion hole 120.

Second, as shown in Figures 9 to 11, the gap can be filled by forming a coating portion 610 formed on the surface of the up and down reinforcement member 210, this embodiment is the coating portion 610 in the factory Produces a reinforcing member with, so that it can be installed immediately in the field, it is possible to obtain the effect that the construction is easy and shorten the air.

Here, the coating part 610 is generally formed by concrete, reinforced concrete, but may also be formed by materials such as reinforced concrete, plastic, reinforced plastic, wood, stone, and the like, and characteristics of each reinforcing member or surface material block. Depending on the different materials may be used.

Since the height of the reinforcing bars and the like used as the up and down reinforcing member 210 is limited, as the height of the retaining wall increases, a joint structure of a plurality of reinforcing members is required, which is connected to the reinforcing member as shown in FIGS. 9 and 10. In the case where the coating part 610 is formed, a more rigid structure can be obtained.

Furthermore, when the up-down reinforcement member 210 formed in the covering part 610 takes the lap structure, a more rigid structure can be obtained.

In addition, the up and down reinforcement member 210 is required to be fixed with the front and rear reinforcement member 200 by the reinforcing member connecting means 300, as shown in Figure 11, the coating portion 610 and the coating portion 610 The connection part 211 is formed in the area | region between them, and the reinforcement member connection means 300 is attached to the up-down reinforcement member 210 exposed by the connection part 211, and the up-down reinforcement member 210 and the surface material Solid fixing of the block 100 and firm fixing of the up-down reinforcing member 210 and the front-rear reinforcing member 200 may be simultaneously obtained.

This makes the coupling of the chain 350 and the up-down reinforcement member 210 easier and more stable by the ring 340, and the deformation behavior of the chain 350 according to the reinforcement soil 500 when it causes ground subsidence. It is softened so that the overall stability of the structure can be secured.

Here, the front and rear reinforcement member 220 may use any of the materials and structures exemplified above, but in order to more easily engage with the rear end of the chain 350, a twisted wire having a spiral twist structure may be applied. It is preferable.

In addition, depending on the situation, two vertical reinforcement members 210 and one front and rear reinforcement member 220 may have a fixed structure.
