Description

Slope structure construction method using wire ring

The present invention relates to a method of constructing a slope structure using wiring. In detail, it not only minimizes the construction period by encouraging the quick and safe installation of the slope structure and suppresses the occurrence of safety accidents, but also reduces impact energy. This relates to a method of constructing a slope structure using wiring that efficiently absorbs and blocks soil or falling rocks from entering the road.

Generally, when constructing a road that includes a mountainous area, an artificial cut surface or slope is formed due to cutting, etc. In such a cut surface or slope, the rock fragments are separated from the parent rock due to the relaxation of the discontinuity within the bedrock, causing rockfall. In addition, rockfall prevention facilities are installed because there are concerns about large-scale rock collapse.

The construction of such rockfall prevention facilities is divided into reinforcement and protection methods according to their functions. Reinforcement methods include cutting methods, surface preparation, anchors, rock bolts, concrete buttresses, concrete block methods, shotcrete, and drainage methods. Construction methods include rockfall prevention nets, rockfall prevention fences, rockfall prevention retaining walls, rockfall tunnels, and vegetation methods.

As an example of a rockfall prevention net, a protection net is covered on a cut slope or slope, and longitudinal and transverse wire ropes are installed on it at regular intervals, and the intersection points of these wire ropes are fixed with fixtures or anchored to the ground with anchor bolts, etc. Safety nets are used, which prevents various accidents by suppressing the occurrence of falling rocks on cut surfaces or slopes and guiding them under the rockfall prevention net in case of falling rocks to prevent them from flying out.

The wire rope safety net is largely divided into pocket type and curtain type. The pocket type safety net is made by attaching a PVC coated net to the rock wall, crossing the wire rope in the longitudinal and horizontal directions at intervals of several meters, and then selecting each intersection point. It is fixed with a binding clip and anchor bolts are fixed to the bedrock to increase the resistance of the wire rope at certain positions to increase the bearing capacity of the PVC coated net and wire rope. The curtain-type safety net is installed at the top without an anchor bolt installed in the middle. It reinforces anchor bolts only on the left and right sides and is mainly used on cut surfaces consisting of soft rock or weathered rock where the rock is severely cracked and weathering progresses rapidly.

As a related prior art, Korean Patent Publication No. 2001-0086663 (published 20010915) discloses a core material inserted into a plurality of holes drilled in a grid shape on the cutting slope, and a core material injected into the tip of the hole to anchor the core material in the ground. A plurality of reinforcements consisting of grouting; A plate-shaped acupressure plate with a hole formed in the center into which the core material is inserted; It is installed on the acupressure plate and consists of a flat plate smaller in size than the acupressure plate and a wall protruding along the circumference of the lower surface of the plate. A hole is formed in the center of the plate into which the core material of the reinforcement material is inserted, and the wall is spaced at 90 degree intervals. A fixture having a plurality of guide holes; Liner screws and nuts for anchoring and fixing the core material of the reinforcement onto the anchoring hole; And a connection wire that is inserted through the guide hole of the anchor and binds a plurality of anchors installed in a grid to each other.
