Meanwhile, the four sides of the main body 100 of the present invention are formed by the net part 110.

Here, the hole size of the net portion 110 may be all formed identically.

On the other hand, as shown in FIG. 5, the hole sizes of the net portions 110 may be formed to have different sizes.

This is an efficient structure for preventing the aggregates 10 from being separated from each other when the aggregates 10 having different sizes are filled.

In order to further improve the above-mentioned prevention effect, a plurality of mesh portions 110 may be formed overlapping each other (FIG. 6).

In this case, each of the plurality of mesh portions 110 and 110a is formed with holes of different sizes.

With this structure, it is possible to more effectively prevent the aggregate 10 from being separated when the aggregates 10 having different sizes are filled.

In addition, in the above structure, only the mesh portion 110 having a large hole size is usually used, and the mesh portion 110a having a small hole size may be additionally laid over the mesh portion 110a.

It is preferable that the main body 100 is mounted with the fixing frame 140 along the rims of the upper portion 101 and the bottom portion 103 to maintain the shape thereof (Fig. 7).

That is, since it is difficult to maintain the shape of the net portion 110 of the main body 100, it is possible to maintain the shape of the net portion 110 by mounting the fixing frame 140 along the upper and lower edges, It is possible to obtain an advantage that the installation work is stable and facilitated.

Here, the fixed frame 140 may be of any material that satisfies the above function, but it is preferably formed of rubber or similar flexible material.

The method for restoring the loss chamber using the structure for restoring the loss chamber of the present invention is as follows.

A main body installation step for installing the main body 100 in the oil chamber 3 of the road 1 or the slope 2 and an aggregate filling step for filling the aggregate 10 in the main body 100 are performed.

The main body 100 is mounted on the inside of the guide frame 30 to fill the aggregate 10 in the main body 100 (FIGS. 8 and 9).

That is, since the work of filling the aggregate 10 in the main body 100 having the cross section of the net 110 may be difficult in the field, it is possible to easily and efficiently perform the aggregate filling step through the guide frame 30 will be.

Here, it is preferable that the guide frame 30 has a very simple structure, and is formed so as to be able to effectively support the guide frame 30 from the outside of the main body 100.

Therefore, the guide frame 30 is provided with a bottom support portion 31 formed to have the same structure as the bottom portion 103 and a side support portion 102 supporting the side portion 102 of the main body 100 to support the bottom portion 103 of the main body 100 And a plurality of side support portions 32 protruding upward from the bottom support portion 32 (FIG. 8).

Further, it is more preferable that the guide frame 30 includes a partition wall portion 33 provided between a plurality of side support portions 32 (Figs. 10 to 14).

The partition wall portion 33 is provided with a plate member 34 closing a space between the plurality of side support portions 32 by a predetermined height along the upper direction of the side support portion 32, And the frame 35 is coupled to the barrier rib structure.

The structure of the guide frame 30 is advantageous in that workability can be improved by supporting the main body 100 more stably when the aggregate 10 is filled in the main body 100.

After the aggregate filling step, a filling step of filling the filler 20 in the interior of the main body 100 is performed to fill the gap between the aggregates 10 and the gap between the main body 100 and the oil chamber portion (FIG. 15).

Here, the charging step is performed by using a mortar mixer, pump equipment, or the like.

In the present invention, the filler 20 may be filled immediately after the main body 100 is filled with the aggregate 10 as described above.

When installing the oil chamber portion 3 of the road 1, after the main body 100 is installed, the first construction is completed by filling the aggregate 10 inside, and then the road is opened.

As a result, the quick recovery work is sufficiently performed, and the aggregate 10 is naturally collapsed as the road is opened.

Further, it is possible to secure a sufficient supporting force even without external compaction through filling of the gap.

Then, after a lapse of a predetermined period of time, the container can be utilized as a port restoration facility through a secondary construction in which the filler 20 is filled in the main body 100.

As described above, the loss chamber restoration method of the present invention is advantageous in that it can satisfy both simultaneous concepts of quick, emergency recovery and port restoration.

On the other hand, the filler 20 used in the oil chamber restoration method of the present invention can obtain high flow properties by incorporating air bubbles into the basic composition of the mortar composition.

This makes it possible to efficiently fill the space between the aggregates 10 and the spaces between the main body 100 and the oil chamber 3 and to improve the structural stability of the oil chamber 30 by improving the rigidity of the structure .
