Description

Rock construction structure of using anchor and method

The present invention is to use the anchor to use the large site and to ensure the stability of the construction structure when building a retaining wall, such as river banks by stacking rocks such as blasting rock, natural stone, landscape stone, etc. in the construction site in the vertical direction It relates to a rock construction structure and its construction method.

More specifically, in the case of constructing structures such as river banks by stacking rocks in up and down directions, rock and rocks stacked in up and down directions are anchored, geogrid, and tie rods. By binding to the use, and relates to the rock structure and the construction method using the anchor to secure the stability of the structure by preventing the flow and separation of the rock.

In general, when a road, a railroad, or the like is formed in a mountainous terrain or when a complex is formed, the mountain slope is cut to have a predetermined slope to secure a space for forming a road or a complex. Walls are formed when civil works, such as banks, banks, or building works near rivers or lakes.

If these walls are left without special measures, the ground may be weakened by natural disasters such as heavy rain or earthquake, which may result in falling rocks or earth and sand loss. Can cause.

In order to prevent such damage, various types of slope stabilization methods such as concrete retaining wall method and soil nailing method are applied to the wall surface.

As shown in Figure 1, the rock construction according to the prior art,

A second step (S200) of connecting the binding member 14 integrally by welding or the like to the connection member 15 having a lower end fixed to the concrete layer 10, and

A third step (S300) of filling the rubble layer 17 to one side of the soil layer 16 so as to prevent the rock 11 from being separated from the soil layer 16 to be compacted as soil;

Fourth step (S400) to increase the binding force of the rock by the filled concrete layer 18 is filled with concrete so that the binding member 14 and the connecting member 15 is embedded between the rubble layer 17 and the rock layer 12 Wow,

Including the fifth step (S500) for covering the reinforcing member 19 by maintaining a predetermined interval in the up and down direction in the soil layer 16, rubble layer 17, filling concrete layer 18,

The rock 11, the binding member 14, the connecting member 15, and the reinforcing member 19 are integrally bound by the concrete hardening of the filled concrete layer 18. Deviation can be prevented.

Hereinafter, with reference to the accompanying drawings, the rock construction structure and the construction method using the anchor according to an embodiment of the present invention will be described in detail.

As shown in Figure 2 and 3, after the bottom surface of the place where the construction structure is constructed, the ground is weak to prevent the settlement when stacking the rock (11), to prevent the rock 11 Pour the foundation concrete layer 10 on the bottom surface so that it can (see S100).

Drilling holes 13 (for example, formed in a cylindrical shape and a conical shape) are drilled in the rock 11 stacked on the foundation concrete layer 10 using a drill machine to a predetermined depth. .

Bonding member 14 (an anchor bolt is used as an example) to the fixing hole 13 is injected to prevent the flow and separation of the rock 11 from the lamination position to inject an adhesive such as epoxy bond, mortar, etc. After grouting, fix it so that it does not come off. In this case, the technical details of fixing the binding member 14 to the fixing hole 13 formed in the rock 11 so as not to be separated are technical contents used in the art, and thus detailed description thereof will be omitted.

The binding member 14 is integrally connected to the connection member 15 (for example, a chain, steel wire, etc. is used) fixed to the foundation concrete layer 10 (which can be fixed by welding as an example). (See S 200).

Rubble (e.g., 10-30 mm outer diameter gravel having a smaller size than the rock 11) to one side of the soil layer 16 so as to prevent separation of the rock 11 from the soil layer 16 that is compacted as soil. As the stone is used), the water in the soil layer 16 is drained to secure stability of the construction structure (see S300).
