At this time, one end of the tensile wire 21 is coupled to the anchor 20.
Preferably, a hollow tension tube 22 is coupled to the anchor 20, and the tension line 21 is disposed inside the tension tube 22.
That is, the tension tube 22 has one end coupled to the anchor 20 and the other end disposed to the outside of the perforation hole 10, Is coupled to the anchor (20) and the other end is disposed outside the perforation hole (10).
The above-described anchor 20 may be formed using conventional anchor structures disclosed in Korean Patent No. 10-1464683 and Japanese Patent No. 10-1617151, and a detailed description thereof will be omitted.
When the anchor 20 is inserted into the perforation hole 10 and the other end of the tension line 21 exposed to the outside of the perforation hole 10 is pulled, Is inserted into the inner circumferential surface of the perforation hole (10) and is fixedly engaged with the inner circumferential surface of the perforation hole (10) while the wing portion of the anchor (20) do.
That is, as shown in FIG. 1 (b), as the other end of the tension line 21 is pulled, the anchor 20 is expanded and fixedly coupled to the inner circumferential surface of the perforation hole 10.
As shown in FIG. 3 (a), the tube installation step S3 is a step of installing a hollow tube 30 on the inclined surface after the anchor 20 is installed.
At this time, the tensile wire 21 and the tensile pipe 22 pass through the hollow tube 30, and the diameter of the hollow tube 30 is larger than the diameter of the hole 10.
In some cases, the block installation step S4 may be performed immediately without the tube installation step S3.
3 (b), the block installation step S4 includes laminating a retaining wall block 40 on a concrete foundation floor 49 installed in front of the inclined surface, And the other end of the block 40 is inserted through the block 40 so as to be coupled.
In the block installation step S4, a plurality of the blocks 40 are stacked in an upward direction.
The tensile wire 21 and the tensile pipe 22 are formed in the through hole 41 of the block 40. The tensile wire 21 penetrates through the through hole 41, A separate fixing member is coupled to the block 40 to be coupled thereto.
An insertion hole 43 is formed in the upper and lower portions of the block 40 and a fixing pin 44 is inserted in the insertion hole 43 to connect the blocks 40 stacked up and down.
As shown in FIG. 3 (b) and FIG. 4, a coupling groove 48 is formed on the rear surface of the block 40, and in the block installation step S4, The engaging members 45 are inserted into the engaging grooves 48 to engage with each other.

As a matter of course, the filling material 50 may be made of a material other than concrete.
5 (b), the other end of the tensile wire 21 passing through the block 40 is pulled so that the block 40 is inserted into the filler 50 And the other end of the tensile wire 21 is fixedly coupled to the block 40 while being in close contact with each other.
In the tensile bonding step S6, when the filler material 50 is made of concrete, the concrete is hardened.
5 (c), the filling step S7 is carried out in the hollow pipe 30 and the perforation hole 10 through the injection hole 42 formed in the block 40 and the grouting material 55 ).
The grouting material 55 may be filled in the hollow tube 30 and the perforation hole 10 by the filling step S7.
Further, it is also possible to laminate gravel, aggregate, sand or the like on the filler material 50 and plant the plant thereon.
In the present invention, since the grouting material 55 filled in the perforation hole 10 is injected most late, the work is completed without the operator having to wait for the next work after injecting the grouting material 55, The working time can be shortened.
As described above, according to the present invention, a plurality of retaining wall blocks 40 are fixedly engaged and installed by using the anchor 20, so that the retaining wall blocks 40 can be more firmly and easily installed on the inclined surfaces.
The method of constructing the retaining wall of the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the technical idea of the present invention.
