Description

{Eco-friendly debris flow mitigation structure and installation method}

The present invention relates to a structure for reducing damages caused by debris, and more particularly, to an eco-friendly destruction reducing structure and an installation method which are unfolded when debris flows in a state of being laid on the ground.

Generally, mountainous areas occupy more than 70% of the whole country. There are many steep slopes in Korea, and steep slopes are destroyed due to the rainy season, typhoon, and heavy rainfall in summer. Especially, in the slope area of the mountain area, there is an increasing number of cases in which the debris flows into the valley along with the sudden flow of debris, resulting in destruction of the facilities on the downstream side and devastation of the farmland.

Here, soil stone is a phenomenon in which a mountain slope, which has been subjected to weathering for a long period of time, is saturated with water due to heavy rain or rainy season, and its weight can not sustain the frictional force. These debris flows along the valley, including soil, large rocks, and a large amount of driftwood, and these large rocks and driftwood are concentrated at the tip of the stream, so they have great destructive power. Debris from natural terrain can be deposited without great damage if the terrain slope is gentle or if there are reservoirs while moving a great distance along the valley. However, if there are houses, roads, etc., Which causes a great deal of damage. In particular, in the case of roads passing adjacent to the slope of the mountain, the amount of microgravity and the transverse drainage facility are installed to allow the flow generated in the valley portion to pass to the lower portion of the road. Or transversal drainage facilities, and secondly, a large amount of toilets and driftwood flow into the roads to paralyze the function of the road for a long period of time. Thirdly, the water generated in the valley section flows over the roads, scouring and destroying the road- Causing enormous damage.

In order to prevent this, Korean Patent Laid-Open No. 10-2014-0050324 (entitled "Sambang Dam Structure") or Korean Registered Patent No. 10-1317279 (entitled "Mysterious Protected Structure") or Korean Patent No. 10-1289723 The name of the invention: a square dam equipped with a landscape function), and a structure using concrete and reinforcing bars in the valleys and valleys where the earth rock is generated. However, construction of such structures is not only difficult to transport construction materials such as concrete and reinforced concrete due to the influence of the mountainous terrain, but also necessitates the construction of additional roads for construction. Therefore, the construction of the limestone can provide a cause of landslide and landslide disasters There is a problem.

In addition, in Korean Patent No. 10-1437537 (invention: anti-disaster structure by destruction of soil) or Korean Patent No. 10-1262240 (invention: disaster prevention structure by destruction of soil) shown in FIG. 1 A structure may be constructed in which a large number of piles 10 are fixed to an area where debris flows and a fence 11 or a net 12 is installed between the piles to accommodate soil or rock. However, this structure is disadvantageous in that since the fence 11 or the net 12 is erected from the installation point, the movement path of the animal may be cut off, and natural scenery and aesthetics may be damaged.

Korean Patent Publication No. 10-2014-0050324 (published April 29, 2014) Korean Patent No. 10-1317279 (issued October 10, 2013) Korean Registered Patent No. 10-1289723 (Bulletin published on July 26, 2013) Korean Registered Patent No. 10-1437537 (Announced 2014.09.05) Korean Patent No. 10-1262240 (Announcement of May 15, 2013)
