Description

Slope reinforcement and protection method using wire block {CONSTRUCTING METHOD FOR REINFORCING AND PROTECTING THE SLOPE USING WIRE BLOCK}

The present invention relates to a slope reinforcement and protection method using a wire block, and in particular, slope reinforcement and protection using a wire block to prevent the occurrence or collapse of falling rocks by protecting and reinforcing slopes such as rockfall areas. It is about a method.

In general, by covering the rockfall protection net closely on the slope of the rockfall area and the like and installing a plurality of wires horizontally and vertically on the top of the rockfall prevention net to firmly support the rockfall prevention net so as to prevent safety accidents that may occur on the slope. It was.

Such a prior art has a problem that when the pressure is largely generated due to the ground behavior of the slope, the slope is almost obsolete and the entire slope collapses causing serious safety accidents.

In particular, the slope is mainly located on the side of the road due to the road construction, so it must be quickly restored to smooth the flow of traffic after an accident. Since only the rockfalls of the dog are blocked, there is a high possibility that the entire slope will collapse when a large pressure is applied due to ground pressure caused by water pressure or soil pressure.

Furthermore, when the entire slope collapses, a considerable amount of time and manpower must be invested to recover it, resulting in an increase in recovery cost and a problem of blocking traffic flow.

In particular, in case of reinforcing the slope, there may be a case of reinforcing by constructing a plurality of concrete blocks on the slope so as to be mutually connected to the surface. Pour hardening to reinforce the slope, so the construction is very difficult due to the slope of the slope, even if the slope is a large slope there was a problem that the construction itself is impossible.

Furthermore, these concrete blocks are not variable at all, so if an initial phenomenon of ground behavior occurs, not only can not appropriately cope with this problem, it is almost impossible to reconstruct due to the change of the terrain during partial collapse, there was a problem to rebuild a large area.

In addition, due to the cumbersome and cumbersome construction of the concrete block, the construction cost is greatly increased and the construction period takes a long time, and the bearing capacity of the slope acts only on the surface.

Therefore, the main object of the present invention is to firmly reinforce and protect the slopes located on the side of the road to maximize its bearing capacity, so that even if the ground behavior due to the earth pressure or the rise of water pressure is large, the slopes can be firmly supported and collapsed. It is to provide a slope reinforcement and protection method using a wire block.

Another object of the present invention is to provide a slope reinforcement and protection method using a wire block to minimize the collapse even if a strong pressure rises on the slope to quickly recover.

Another object of the present invention is to provide a slope reinforcement and protection method using a wire block that can be easily and quickly protect, reinforced.

Another object of the present invention is that when the partial collapse or initial collapse of the slope occurs, these parts can be separated and reassembled firmly or replaced with new wire blocks to be reassembled firmly, thereby quickly reinforcing the signs of collapse or partial collapse. The present invention provides a method for reinforcing and protecting slopes using wire blocks that can prevent the collapse of the entire slope in advance.

Another object of the present invention is to provide a method for reinforcing and protecting a slope using a wire block to shorten the construction period and reduce the cost, so that the slope can be easily and quickly reinforced.

Another object of the present invention is to provide a slope reinforcement and protection method using a wire block to be installed on the surface of the rockfall prevention net to maximize the rockfall prevention effect and reinforce the rockfall area to maximize the effect.
