In addition to this, if the rail rod 200 is pivotally coupled to the pile plate 120 and has a detachable coupling structure, it is also possible to be formed to be coupled with a different structure as needed. A plurality of such rails 200 are provided and sequentially coupled in the height direction of the cut surface.

On the other hand, the rail 200 may be connected to the pile plate 120 and the connecting rod 400 .

The retaining plate 300 is to form a plate shape, and is inserted between the rail rods 200 formed for each support line 100 between the support lines 100 formed adjacently. A plurality of pieces are provided and arranged in a horizontal direction to block between the rails 200 by being sequentially inserted one after another. This retaining plate 300 serves to support the cut surface so as not to collapse.

The retaining plate 300 may be mounted on a frame 320 woven at an angle of an 'L' shape in cross section. A structure in which a plurality of retaining plates 300 are mounted to the frame 320 and configured to be set, in this configuration, the standard of the frame 320 is formed to match the length of the rail stand 200 , and the frame 320 .

Hereinafter, a method for reinforcing the incision surface using the incision surface reinforcement device according to the present invention as described above will be mainly described with reference to FIGS. 4 to 14 . A method of reinforcing the cut surface generated by excavating the ground will be described as an example.

(S1) support line formation step

When the point at which the ground is to be excavated is determined, the pile plate 120 is driven into the ground in a direction that intersects the cut surface formed during excavation to connect the pile plate 120 to form the support line 100 . The support line 100 is formed over the whole at regular intervals in the width direction of the cut surface. At this time, the same length of the pile plate 120 forming the support line 100 may be adopted, and the length of the pile plate 120 may be different from each other as needed.

(S2) 1st step of retaining

When the formation of the support line 100 is completed, the excavation point is excavated once to a predetermined depth (FIG. 4). Accordingly, a cut surface is formed, and the end of the support line 100 is exposed as the cut surface. The end of the pile plate 120 forming the end of the support line 100 is exposed. The end of the pile plate 120 is exposed for each support line 100 formed at regular intervals.

Each rail stand 200 is installed at the end of the pile plate 120 exposed as described above (FIG. 5). The rail 200 is formed in a plank shape and is coupled to the end of the pile plate 120 along the midpoint in the longitudinal direction, and at this time, it is installed in a state that can be rotated with each other, and if necessary, the rail rod using the connecting rod 400 (200) is installed at the end of the pile plate (120).

Thereafter, the retaining plate 300 is inserted between the rails 200 between the support lines 100 to the depth excavated the first time (FIG. 6). Therefore, since the retaining plate 300 supports the earth pressure in the cut surface, the cut surface does not collapse (FIG. 7).

Here, the retaining plate 300 may be mounted on a frame 320 woven at an angle of an 'L' shape in cross section as shown in FIG. 3 . According to this, by providing a plurality of retaining plates 300 of a certain width and mounting them on the frame 320, it is possible to set them, so that it is possible to install several retaining plates 300 at a time. In this configuration, if a roller is installed in the frame 320 at a point in contact with the rail 200, it may be formed to reduce friction in the descending or ascending process.

Meanwhile, a wire 500 surrounding the edge and the lower end of the retaining plate 300 may be installed between the rails 200 ( FIG. 3 ). The wire 500 is of a sufficient length, and descends along with the descent of the retaining plate 300 even in an additional retaining step to be described later, and both ends form a length that can always be exposed above the rail 200 . These wires 500 are selectively installed only at necessary points.

(S3) additional retaining step

After the first round of retaining, the excavation point is additionally excavated to a certain depth (FIG. 8). The depth that was excavated during the first retaining stage is excavated. Of course, the depth of excavation can be adjusted as needed.

When the additional excavation is performed as described above, the pile plate 120 at the end of the support line 100 is exposed as a cut surface formed as the additional excavation is performed. The rail bar 200 is installed at the end of the pile board 120 exposed in this way (FIG. 9), at this time, the rail bar 200 installed in the first retaining step is pressed down, and the rail bar 200 is thereon. Installation is possible by additionally installing (FIG. 10).

When the installation of the rail stand 200 is completed as described above, the retaining plate 300 is inserted between the rail stands 200 to the depth excavated for the additional rounds (FIG. 11). The retaining plate 300 is installed in such a way that the previously installed ones descend and the additionally installed ones are installed in the position of the previously installed ones by pressing while stacking the additional retaining plates 300 on top of the ones installed in the first retaining step. will do This additional retaining step is repeated a plurality of times to construct the retaining plate 300 to a desired depth (FIG. 12).

(S4) 1st retaining wall construction stage

When the construction of the retaining plate 300 is completed to the desired excavation depth, one row of the retaining plate 300 is lifted (FIG. 13). It is lifted by a height equal to or longer than the length of the unit rail stand 200 from the bottom. When the wire 500 is installed, the wire 500 is pulled upward and lifted. Accordingly, the space in which the retaining plate 300 is removed is formed between the support lines 100 , that is, between the rail rods 200 installed at the end of the support line 100 , so that the retaining plate 300 is removed. .

After that, the rail 200 is rotated toward the space. When this is rotated, the gap between the rails 200 in the row adjacent to the row from which the retaining plate 300 is removed is widened. As a result, the rail rod 200 that prevents the retaining plate 300 from being pushed forward is removed, and thus the retaining plate 300 can be separated and removed in front of the cut surface (FIG. 14).

A retaining wall is constructed at the point where the retaining plate 300 is removed as described above, and the first retaining wall is constructed while repeating this process in the width direction of the cut surface. Accordingly, the first retaining wall is constructed and reinforced on the cut surface.

(S5) Additional retaining wall construction stage

When the first retaining wall construction is completed, the same process is repeated to construct the retaining wall up to a predetermined height. An additional retaining wall is constructed on top of the previously constructed retaining wall while additionally lifting the retaining plate 300 in one row by a height equal to or longer than the length of the unit rail stand 200, and then removing the retaining plate 300 in an adjacent row. , to construct the retaining wall by repeating this process throughout the cut surface.

Through the process as described above, the cut surface is reinforced while excavating, and a retaining wall can be constructed on the cut surface. According to this, since the retaining wall can be constructed while removing the retaining plate 300, recycling of the retaining plate 300 This becomes possible.
