Description

Fence for preventing falling stone using waste tire}

The present invention relates to the fall prevention and fall prevention measures installed in civil works and road construction sites. More specifically, it is possible to prevent the steel pipe pillars and wire mesh from being damaged by falling rocks and falling rocks in the slopes caused by road opening. In general, it is related to the prevention of falling rocks using waste tires.In general, when a loose rock mass existing on a slope with falling rocks and rocks is left unattended, the rock moves to the lower slope with large kinetic energy and moves to houses, buildings, and roads. It can cause great damage to the back, and furthermore, the relaxed rock moves down the slope, causing the surrounding mass to move, causing greater damage to the lower slope. Therefore, in order to protect nearby structures from rockfall, rockfall prevention measures are usually installed.

In Figs. 1A to 1C, reference numeral 1 is ground, and reference numeral 2 is a round steel pipe. Reference numeral 3 is cement for fixing the steel pipe 2 to the ground 1, and reference numeral 4 is a rock mass. Reference numeral 7 is a wire mesh, and reference numeral 8 is a drilling hole for inserting a steel pipe (2).

Looking at the conventional rockfall prevention measures of the above structure, after simply inserting the steel pipe (2) to the ground (1), it is configured in such a way that between the steel pipe (2) and the steel pipe (2) with a wire mesh (7). Therefore, when a rockfall with a large impact energy occurs on the slope, the installed round steel pipe 2 fails to absorb the impact energy of the rockfall. In addition, rockfalls that penetrate between the wire mesh 7 may invade the road and cause traffic accidents, and may cause other safety accidents.

The present invention has been devised to improve the problems of the conventional rockfall prevention measures as described above, it is possible to prevent the steel pipe pillars and wire mesh from being damaged by the heavy weight of rockfall and falling that occurs on the slope existing in civil engineering and road construction sites The purpose is to provide a rockfall prevention measures using waste tires.

Rockfall prevention measures using waste tires according to the present invention in order to achieve the above object, to be installed in front of the inclined surface of the road cut slope or the slope of the mountain to prevent rock and rock from invading the road into the ground, In the fall prevention measures provided with a plurality of circular steel pipes installed vertically, and a wire mesh installed on the circular steel pipes to block between the plurality of circular steel pipes, Between the plurality of circular steel pipes installed perpendicular to the ground and the inclined surface of the incision Anchoring loops for reinforcing the resistance of circular steel pipes against impact of rockfall and rock fall are respectively installed at right angles to each circular steel pipe, and the space between the fence and the slope consisting of the circular steel pipe and the wire mesh is in It is characterized by the fact that a number of waste tires are filled to alleviate the impact caused. Like this, by connecting the anchor to the circular steel pipe installed perpendicularly to the ground, the steel pipe is connected with the ground of the side slope one more time, and the waste tire is filled between the fence and the slope, so that the impact load caused by the massive rockfall and fall It is possible to protect the vertical circular steel pipe and wire mesh from the.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 (A) to (C) shows the structure of the rock fall prevention measures using the waste tire according to the present invention, (A) is a side view, (B) is a front view, (C) is a perspective view.

Referring to Figures 2 (A) to (C), the rockfall prevention measures using the waste tire according to the present invention is installed in front of the inclined surface of the road cut slope or mountain slope to prevent the falling rock and fall from the slope to the road For the purpose, basically a plurality of circular steel pipe (2) installed perpendicular to the ground (1), and a wire mesh (7) installed in the circular steel pipe (2) so as to block between the plurality of circular steel pipe (2) basically Equipped. In addition, between the plurality of circular steel pipe (2) installed perpendicular to the ground (1) and the inclined surface of the incision site, an anchor loop for reinforcing the brace resistance of the circular steel pipe (2) against the impact force of the falling rock and rock ( 6) is further installed at approximately right angles to each circular steel pipe (2). Here, one such an anchor loop 6 may be provided in each circular steel pipe 2, but preferably two in each circular steel pipe 2 for reinforcing force of the circular steel pipe 2, respectively. In addition, the space between the fence and the slope consisting of the circular steel pipe (2) and the wire mesh 7 is filled with a number of waste tires (9) for mitigating the impact caused by falling rocks and falls.

Construction of a rockfall prevention measure using waste tires according to the present invention as described above, first, a plurality of circular steel pipes (2) are inserted in a line in the drill hole (8) spaced apart from each other at predetermined intervals on the road surface of the road where the slope exists. . At this time, the alignment interval of the circular steel pipe (2) is installed about 2m. And it is preferable that the depth which the steel pipe 2 is buried in the ground 1 inserts in about 1m-2m. The cement (3) grouting is performed to fix the circular steel pipe (2) inserted into the drilling hole (8) to the ground (1). When the insertion of the steel pipe and the cement grouting is completed, the drill hole 8 for fixing the anchor loop 6 is formed in the rock mass 4 of the slope. When the formation of the drilling holes 8 is completed, the anchor loop 6 is inserted into each of the drilling holes 8, and then cement grouting is performed. After the curing period of the cement, the anchoring loop (6) coming out of the slope rock (4) is fixed to the pre-installed circular steel pipe (2) using an angle (5). After the binding between the anchor loop 6 and the round steel pipe 2 is completed, the wire mesh 7 is mounted between the respective round steel pipes 2. Then, a plurality of waste tires 9 are finally filled in the space between the fence and the slope formed of the steel pipe 2 and the wire mesh 7. At this time, it is preferable that the stacking height of the waste tire 9 is piled up to approximately 1m below the tip of the steel pipe 2.

When the rockfall prevention measures are installed in the above manner, the impact energy of the rockfall is absorbed by the anchor loop 6 and the waste tires 9, thereby preventing the steel pipe 2 and the wire mesh 7 from being damaged by the rockfall. Therefore, it is possible to prevent damage to the surrounding roads and traffic accidents caused by falling rocks.

As described above, according to the fall prevention measures using the waste tire according to the present invention, to strengthen the propulsion resistance of the round steel pipe against the impact force of the falling rock and rock fall between the slope of the incision site and a plurality of circular steel pipe vertically installed on the ground An anchor loop is installed, and waste tires are filled between the slope and the fence, so that rockfalls generated on the slopes can be more firmly prevented, and in case of heavy rockfalls, steel pipes and wire meshes can be prevented from being broken. In addition, it is possible to prevent damage to surrounding roads, traffic accidents and casualties caused by falling rocks.
