Hereinafter, with reference to the accompanying drawings, it will be described how to replace the natural retaining wall for replacing the concrete retaining wall of the roadside that is prone to corrosion, freezing and melting due to the use of calcium chloride during snow removal operations.

First, a part is buried in the ground of the roadside, and the rest is provided with a first natural face stone 10 exposed to the top of the roadside.

Here, the retaining wall lower support unit 100 in the lower portion of the first natural noodle (10) in order to prevent the separation of the first natural noodle (10) from the road side before installing the first natural noodle (10). Install.

Next, the second natural noodle (20) is installed on the upper portion of the first natural noodle (10). Here, the shake prevention unit 200 is installed on the upper surface of the first natural face stone 10 before the second natural face stone 20 is installed.

Next, an anti-shake unit adjusting step of adjusting the height of the anti-shake unit 200 to prevent shaking of the second natural face stone 20 after the second natural face stone 20 is installed is performed.

The anti-shake unit adjusting step is to change the height of the upper member 240 while rotating the upper member 240 is screwed with the lower member 210 disposed on the upper surface of the first natural stone 10, the The first intermediate member 221 and the second intermediate member 231 disposed between the lower member 210 and the upper member 240 are moved upward.

Next, one side is fixed to the second natural face stone 20, the other side is a natural face stone fixing unit installation step of installing a natural face stone fixing unit fixed to the slope of the road side is performed.

The natural stone stationary fixing unit installation step is to install a slope fixing anchor 500 is fixed to the slope of the road side, natural natural stone stationary anchor to install a natural stone stationary anchor 300 to the second natural stone 20 And installing an anchor connection member 400 connecting the inclined fixed anchor 500 and the natural noodle fixed anchor 300.

The natural stone stationary anchor installation step is installed elastic member to install an elastic member for elastically holding the blades 320 on the outer surface of the plurality of blades 320 is inserted and fixed to the second natural stone (20) And inserting the insertion member 310 into the anchor head of the natural noodle fixing anchor 300 and then moving the blades 320 to open the fixing head 310 to the second natural noodle 20. And an insertion movement step.

The elastic member installation step is to install a first elastic member 333 in the boundary region of the blade front portion 321 and the blade middle portion 323, the blade middle portion 323 and the toothed blade (325a) ) And installing the second elastic member 331 in the boundary region of the blade rear portion 325.

The insertion movement step is performed in the following order.

First, before the anchor head is inserted into the anchor insertion groove 21 of the second natural face stone 20, it has a shape as shown in FIG. 5A. Specifically, in the state where the front portions of the blades are not opened, the outer diameter of the rear portion of the blades at which the toothed blades 325a are positioned is the virtual line of the anchor insertion groove 1 that virtually expresses the anchor insertion groove 21. Have a diameter larger than the diameter.

In the state of FIG. 5A, since the anchor head cannot be inserted into the anchor insertion groove 21, a work for reducing the outer diameter of the anchor head is required.

Specifically, as shown in the shape of the anchor head shown in Figure 5b, the insertion member head on the first locking step (321a) formed in the blade front portion 321 before the anchor head is inserted into the second natural face stone 20 A first step of moving the insertion member 310 forward to take the 313 is performed.

Next, as shown in FIG. 5B, a second step of inserting the anchor head into the anchor insertion groove 21 is performed while the insertion member head 313 is caught by the first locking jaw 321a. do.

At this time, since the outer diameter of the anchor head is smaller than the anchor insertion groove 21, the anchor head can be easily inserted into the anchor insertion groove 21.

Next, the insertion member head 313 is rearward along the inner surface of the blade front portion 321 and the inner surface of the blade middle portion 323 to fix the anchor head to the anchor insertion groove 21. A third step of moving to is performed.

When the insertion member head 313 is moved backward, the blade 320 is opened because the inner surface of the blade front portion 321 and the inner surface of the blade rear portion 325 are inclined. .

In particular, as shown in Figure 5c, the rear tooth blade formed in the rearmost of the blade rear portion 325 is fixed while primarily contacting the inner wall of the anchor insertion groove (21).

Next, as shown in FIG. 5D, when the insertion member head 313 is continuously moved backward, the rearmost portion of the blade rear portion 325 is no longer due to the inner wall of the anchor insertion groove 21. Since it cannot be opened, the blade middle portion 323 and the blade front portion 321 are opened.

As a result, the insertion member head 313 is moved backward until all the tooth blades 325a formed in the blade rear portion 325 are firmly fixed while being lodged in the inner wall of the anchor insertion groove 21.

Here, the insertion member head 313 may be moved until the movement in the rear by the second locking jaw (323a) is limited, but all the toothed blades (325a) foil in the anchor insertion groove (21) The rear side of the insertion member head 313 can be stopped.

Next, when the anchor head is fixed to the anchor insertion groove 21, the insertion member body 311 is connected to the anchor connecting member 400.

Of course, the reflector plate unit 600 for reflecting the light of the vehicle is installed on the front surface of the second natural face stone 20 independently of the anchor head is fixed to the anchor insertion groove 21.

As described above, the present invention is not limited to the above-described specific preferred embodiments, and various changes and modifications may be made by those skilled in the art without departing from the scope of the present invention as claimed in the claims. And such variations are within the scope of the present invention.
