Description

Debris flow prevention structure using wire ring

The present invention relates to a debris flow prevention structure using wiring, and more specifically, to a debris flow prevention structure using wiring that can efficiently block debris flow such as soil and gravel and suppress the flow at the same time depending on the characteristics of the terrain in a valley, etc.

In general, when constructing a road that includes a mountainous area, an artificial cut surface or slope is formed by cutting, etc., and on such a cut surface or slope, not only can rock fragments be separated from the parent rock due to the loosening phenomenon of the discontinuity in the rock, causing rockfall, but there is also a concern about rock collapse in which large amounts of rock fall, so rockfall prevention facilities are installed.

The construction of these rockfall prevention facilities is divided into reinforcement methods 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. Protection methods include rockfall prevention nets, rockfall prevention fences, rockfall prevention retaining walls, rock tunnels, and vegetation methods.

As an example of a rockfall prevention net, a wire rope safety net is used in which a protective net is covered on a cut slope or incline, and longitudinal and transverse wire ropes are installed at regular intervals on top of it, and the intersections of these are fixed with fixtures or anchored to the ground with anchor bolts, etc. This suppresses the occurrence of rockfall on the cut slope or incline, and in the event of rockfall, guides the rocks under the rockfall prevention net so that they do not fly up, thereby preventing various accidents.

The above 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 ropes longitudinally and transversely at intervals of several meters, selecting each intersection point and fixing it with a tie clip, and then fixing anchor bolts to the rock at regular intervals to increase the resistance of the wire rope, thereby increasing the bearing capacity of the PVC coated net and wire rope. The curtain type safety net is made by reinforcing anchor bolts only at the top and left and right sides without installing anchor bolts in the middle, and is mainly used in cut surfaces composed of soft rock or weathered rock with severe cracks and rapid weathering.

As a related art, Korean Patent Publication No. 2001-0086663 (published on September 15, 2001) discloses a slope reinforcement device using a connecting wire, which comprises: a plurality of reinforcing materials each composed of a core material inserted into a plurality of holes perforated in a grid pattern on a cut slope and grouting injected into the tip of the holes to anchor the core material into the ground; a plate-shaped pressure plate having a hole formed in the center into which the core material is inserted; an anchoring member comprising a flat plate installed on the pressure plate and smaller in size than the pressure plate and a wall protruding along the lower perimeter of the flat plate, wherein a hole into which the core material of the reinforcing material is inserted is formed in the center of the flat plate and a plurality of guide holes are formed at 90-degree intervals in the wall; a liner screw and nut that anchor and fix the core material of the reinforcing material on the anchoring member; and a connecting wire that is inserted through the guide holes of the anchoring member and connects the plurality of anchoring members installed in a grid pattern to each other.

In addition, Korean Patent Publication No. 10-2010-0138967 (published on December 31, 2010) discloses a rockfall prevention structure covering a slope by a net assembly including rope members joined in a cross direction and a wire net connected to the rope members, wherein the net assembly is fixed to the slope by a fixing means, wherein the fixing means is one or more anchors inserted into the slope to stabilize a surface layer of the slope, and the anchor and net assembly have sufficient strength to suppress movement of a rock mass identified on the slope.

In particular, the registered patent No. 10-2476908 (registered on December 8, 2022) previously applied for by the present applicant comprises a main support forming step for forming concrete blocks to fix a pillar, a wiring net joining step for connecting a plurality of wirings between the concrete blocks in a regular manner in the up, down, left, and right directions with a wiring net, a lower wiring net joining step for connecting a lower wiring net downward to the wiring net joined between the concrete blocks to cover the lower valley, and a structure construction step for fixing the outer shell of the lower wiring net. Therefore, even if debris such as graffiti flows down, it is blocked and at the same time, the lower wiring net is guided to pile up inward to efficiently prevent the debris flow from flowing down. The debris flow prevention structure is disclosed, which efficiently absorbs impact energy by the shrinkage/expansion and elastic means of the wiring net and controls it by guiding the debris flow inward from the lower wiring net, so that not only is the debris flow blocking efficiency very high, but also can continuously maintain the valley stably.

However, these conventional technologies have limitations in blocking debris flows in valleys, and there has been a continuous demand for the development of new technologies that can block debris flows efficiently and stably.

Therefore, the main purpose of the present invention is to provide a debris flow prevention structure using wiring that safely and stably blocks debris flows such as soil and gravel generated in valleys and the like, thereby efficiently suppressing damage caused by debris flows.

Another object of the present invention is to provide a debris flow prevention structure using wiring that efficiently absorbs impact energy generated by debris flow such as soil or gravel, and at the same time guides it downward and gradually blocks it, thereby preventing safety accidents caused by the inflow of debris flow.

Another purpose of the present invention is to provide a debris flow prevention structure using wiring that senses impact energy generated by debris flows such as sand or gravel and immediately reports the same, thereby enabling rapid response and significantly reducing damage caused by debris flows.

In order to achieve the above object, the debris flow prevention structure using wiring of the present invention is characterized in that it comprises a support fixing part having guide posts formed on the left and right sides of a support plate, a beam fixing part having a support plate that is in close contact with the upper side of the support fixing part while forming connection ports at the front and rear sides of the support plate and forming a pair of reinforcing support plates between the connection ports, a support part connecting a main support by erecting it on the guide posts of the support fixing part, a beam part connecting an H-beam to the connection ports of the beam fixing part by laying it on the ground front and rear respectively, a wiring net part connecting to the main support of the support part and the H beam of the beam part, and a wire rope part organically connecting the wiring net part between the main support of the support part and the H beam of the beam part.

Therefore, the debris flow prevention structure using wiring of the present invention is fixedly installed by overlapping the support plates of the beam fixing part on the support plates of the support fixing part on the left and right sides, and then the lower part of the main support is inserted between the guide support and the reinforcing support plate of the support fixing part and axially connected, and at the same time, the H beam is axially connected to the connecting holes formed in the front and rear of the beam fixing part and fixed to the ground, thereby reducing the weight and enabling smooth and safe work even in difficult work environments such as slopes, and the assembly wiring net manufactured to a certain size is connected to the upper side of the left and right main support and H beam respectively, and the assembly wiring net is fastened at the center between the left and right main support and H beam, and at the same time, the concave part is connected by weaving the connecting wiring, and then the assembly wiring net is installed on the lower side as described above, and the assembly wiring nets on the upper and lower sides are connected by weaving the connecting wire rope, so that not only the on-site work time is reduced, but also the efficiency of debris flow prevention is improved by firmly connecting them, while organically and firmly fixing them by the upper wire rope and the lower wire rope, etc., so that soil or rubble occurring in valleys, etc. It is effective in effectively suppressing damage caused by debris flows by safely and stably blocking debris flows, gradually blocking debris flows while guiding them downwards, and minimizing safety accidents caused by debris flows as much as possible. In addition, it senses the impact energy generated by debris flows and notifies the user immediately, allowing a quick response and significantly reducing damage caused by debris flows.
