More specifically, the crack initiation hole step S10 punctures a crack hole for a non-vibrating arm and a vibrating arm on a free surface on which a tunnel is to be excavated. As shown in FIGS. 5 and 8, A crack hole (H1) is drilled in a defined area of the free surface to form a large crack hole (H1) cluster and a small crack hole (H2) is formed on the free surface other than the large crack hole (H1) do.

The large crack hole H1 is formed to have a large diameter in comparison with the small crack hole H2. In an embodiment of the present invention, the large crack hole H1 has a diameter of about 105 mm, a small crack hole H2 The diameter can be about 76mm.

Which are illustrative and may be selectively implemented with various diameters according to embodiments to which the present invention is applied.

As shown in FIG. 5, the large crack hole (H1) cluster can be realized by dividing a certain area at the center of the free surface where the tunnel is to be excavated, and puncturing a plurality of large crack holes (H1) Or as shown in FIG. 8, a long section may be disposed on both sides of the lower portion of the free surface on which the tunnel is to be excavated, and the section may extend upwardly from the center to form a region having a shape such as 'ㅗ' have.

Also, the large crack hole (H1) cluster can be implemented in multiple areas on the free surface where the tunnel is excavated.

The depth at which the large crack hole H1 and the small crack hole H2 are drilled is drilled at least twice as long as the length of the main body 110, to be.

In the large crack releasing step S20, the main body 110 of the chalcan system equipped with the extension unit for the long hole crack is inserted into the perforated large crack hole H1 to provide the hydraulic pressure, A first sublimation step of pressing the inner circumferential surface of the crack hole H1 to generate a crack and a step of joining the extension unit 200 while the main body 110 is inserted into the large crack hole H1, The second sub-step of performing the second sub-step is performed by advancing the main body 110 to a deep depth and providing the hydraulic pressure again through the press block 120.

As shown in FIGS. 6 and 7, the bore diameter S, which is a space where the space corresponding to the large crack hole H1 is formed, is formed through the first and second sub-stages.

The sill diameter (S) refers to the space formed in the depth direction of the tunnel to be excavated by non-vibrating arm of the large crack hole (H1), and the larger the depth of the sill diameter S toward the tunnel direction, H1) The more complicated the shape of the segmented region of the cluster is, the more likely it is that the size of the S-shaped free surface generated inside the S-shaped aperture (S) becomes wider.

When the width of the free surface S of the pre-bore S is widened, it is possible to obtain the advantage that the small-fracture assist step S30 to be described later can be performed more quickly.

In the small crack releasing arm step S30, as shown in FIG. 7, the rock breaking operation is performed by applying vibration through the arm equipment M to be oscillated in the small crack hole H2.

The shallow cracks of the small crack hole (H2) proceed from the small crack hole (H2) adjacent to the lead aperture diameter (S) formed through the large crack joint arm step (S20) and the closer to the free surface of the lead aperture diameter (S) So that it can easily proceed.

In the deburring step (S40), the burr generated through the large crack releasing arm step (S20) and the small crack releasing arm step (S30) is removed from the space formed inside the tunnel to the outside.

The support material installation step S50 is a step of reinforcing shotcrete, rockbolt, etc. so that the upper and both walls of the tunnel space formed through the process described above are firmly supported.

Through one of these steps, one excavation process is completed, and the crack initiation step S10, the large crack releasing arm step S20, the small crack releasing arm step S30, the deburring removing step S40, S50) is repeatedly performed along the longitudinal direction of the tunnel.
