Description

토사유출 방지용 매트 고정구{Germinating hole layer structure of vegetation mat} Matte fixture for preventing soil leakage {Germinating hole layer structure of vegetation mat}

본 발명은 절개지 또는 하천 제방 등의 법면에 식생매트, 철망, 녹생매트 등 각종 매트를 고정하기 위한 고정구에 관한 것으로, 상세하게는 매트를 법면에 안정되게 고정시켜 토사의 유출을 방지하는 한편, 잔디 등 식물의 활착 기반을 조성하도록 구성한 것이다.The present invention relates to a fixture for fixing various mats such as vegetation mats, wire netting, green mats, etc. on a legal surface such as an incision or river embankment. It is constructed to create a base for plant life.

일반적으로 매트(mat)는 절개지 또는 하천 제방 등의 법면에 설치되어 토사유출을 방지하고, 잔디 등의 식물이 활착하는 기반을 조성하도록 하는 것이다. 이러한 매트로는 식생매트, 철망, 녹생매트 등이 있으며, 이러한 매트를 절개지 또는 하천 제방 등의 법면에 고정하기 위해서는 매트를 절개지 또는 법면 등에 펼친 다음, 얇고 긴 평철을 길이 방향으로 직각으로 절곡하여(굽힘모멘트를 증가시켜) 형성된 고정구를 망치 등을 이용하여 지면에 순차적으로 박아 고정하게 된다. 또한, 이형 철근을“ㄱ”자로 절곡하여 형성된 고정구를 망치 등을 이용하여 지면에 박아 고정하는 것이다.Generally, a mat is installed on a legal surface such as an incision site or a river embankment to prevent soil leakage, and to create a foundation for plants such as grass. Such mats include vegetation mats, wire netting, green mats, etc., and in order to fix these mats on the incision surface such as an incision or river embankment, the mat is spread out on an incision or a surface, and then the thin and long flat iron is bent at right angles in the longitudinal direction (bending) By increasing the moment), the formed fixture is sequentially fixed to the ground by using a hammer or the like. In addition, the fixed bar formed by bending the reinforcing bar to “a” is fixed to the ground by using a hammer or the like.

그러나 이와 같은 평철 및 이형철근 타입의 고정구는 땅속에 자갈이나 암석이 있을 경우 좌굴을 일으킬 수 있으며, 지반의 다짐도가 약하거나, 비나 강물로 인해 지면의 토사가 팽창과 건조 수축을 반복하면서 다짐도가 떨어지면 쉽게 탈거(빠짐)되는 문제점이 발생되는 것이다.However, this type of flat iron and bimodal rebar type fixture may cause buckling when there is gravel or rock in the ground, and when the compaction of the ground is weak, or when soil or soil on the ground repeats expansion and drying contraction due to rain or river water, the compaction falls. It is a problem that is easily removed (missing).

이러한 문제점을 해결하기 위하여 평철 타입의 고정구의 양단에 줄(와이어)을 매달아 공압을 이용하는 장비로써 고정구를 땅속에 박아 넣은 다음, 표면에 도출된 줄을 이용하여 매트를 고정하는 방법이 제공되었으나, 이 방법의 문제점은 대부분의 공사현장이 일반 주거지역과는 멀리 떨어진 외곽지대에 위치되어 특수장비를 이용하는데 많은 제한이 따르는 문제점이 있는 것이다.In order to solve this problem, a method of fixing a mat using a string derived on the surface after inserting a fixture into the ground as a device using pneumatics by hanging a string (wire) on both ends of a flat iron type fixture was provided. The problem with the method is that most construction sites are located in an outer area far away from the general residential area, and there is a problem in that there are many limitations in using special equipment.

또한, 다른 방법으로는 철근 타입의 고정구를“X"자 형태로 교차하여 땅속에 박아 고정한 다음, 고정구의 교차점을 묶음 선으로 묶어 매트를 고정하는 방법이 있으나, 이는 비용이 많이 소요되고, 작업성이 현저히 떨어지며 교차점의 묶음선이 파단될 경우 교차하여 박은 효과를 상실하게 되는 등의 문제점이 발생 되었다.Also, as another method, there is a method of fixing a mat by tying a reinforcing bar type fastener in an “X” shape and driving it into the ground, and then tying the crossing point of the fastener with a tie line, but this is expensive. When the bundle line at the crossing point breaks apart significantly, problems such as loss of the effect of crossing the crossing occur.

본 발명은 이와 같은 종래의 문제점을 해결하기 위하여 안출된 것으로, 본 발명은 비용이 저렴하면서 작업성이 용이하며, 매트의 고정력을 높여 토사의 유출을 방지하는 한편, 잔디 등 식물이 활착하는 기반을 조성하도록 구성한 토사유출 방지용 매트 고정구를 제공하는 데 그 목적 있다.The present invention has been devised to solve such a conventional problem, and the present invention is a low cost and easy workability, and increases the fixing force of the mat to prevent the outflow of sediment, while providing a foundation for plants such as grass to settle. It is an object of the present invention to provide a mat fixture for preventing soil leakage.

본 발명의 과제 해결 수단은 절개지 또는 제방의 법면에 매트를 고정시켜 토사의 유출을 방지하는 한편, 잔디 등 식물이 활착하는 기반을 조성하게 되는 고정구에 있어서, 자체 탄성력이 구비된 박판의 금속띠로 이루어지고, 하단부에 첨단부가 형성되며, 중앙 영역을 중심으로 상,하부를 반대 방향으로 180°로 비틀어 형성된 나선형고정편과; 상기 나선형고정편 나선형의 비틀림 면을 따라 상호 엇갈리게 일체로 형성된 다수의 날개편으로 구성되어, 상기 매트를 고정시키는 것을 특징으로 한다.The problem solving means of the present invention is to fix the mat on the incision surface of the incision or embankment to prevent the discharge of sediment, while in the fixture to form a base on which plants such as grass are to be formed, it is made of a metal strip of a thin plate with its own elastic force A helical fixed piece formed by twisting the upper and lower parts in the opposite direction by 180° around the central area; The spiral fixing piece is composed of a plurality of wing pieces formed integrally and staggered with each other along the twisting surface of the spiral, and is characterized in that the mat is fixed.

본 발명의 토사유출 방지용 매트 고정구는, 자체의 탄성력이 구비된 나선형고정편의 나선형 비틀림면을 따라 상호 엇갈리게 형성된 다수의 날개편으로 이루어어져, 안정되게 절개지 또는 제방 등의 법면에 각종 매트를 고정시켜, 토사의 유출을 방지하는 한편, 잔디 등 식물이 활착하는 기반 조성이 용이한 효과가 제공된다.The mat fixture for preventing soil leakage of the present invention is composed of a plurality of wing pieces formed alternately along a spiral twisting surface of a spiral fixing piece equipped with its own elastic force, stably fixing various mats on a legal surface such as an incision or embankment, On the other hand, it is possible to prevent the outflow of sediment, while providing an easy effect on the composition of the base on which plants, such as grass, are active.

도 1 및 도 2에 도시된 바와 같이, 본 발명에 따른 토사유출 방지용 매트 고정구는 자체 탄성력이 구비된 박판의 금속띠로 이루어지고, 하단부에 첨단부(12)가 형성되고, 중앙 영역을 중심으로 상하부를 반대 방향으로 180°비틀어 형성된 나선형고정편(10)과;
나선형고정편(10)의 나선형 비틀림면을 따라 상호 엇갈리게 형성된 다수의 날개편(20)으로 이루어져, 절개지 또는 하천 제방 등의 법면에 식생매트, 철망, 녹생매트 등 각종 매트를 고정시켜 토사의 유출을 방지하는 한편, 잔디 등 식물이 활착하는 기반을 조성하도록 구성한 것이다.
1 and 2, the mat fixture for preventing soil leakage according to the present invention is made of a metal strip of a thin plate equipped with its own elastic force, the tip portion 12 is formed at the lower end, and the upper and lower parts are centered around the central region. And a spiral fixing piece 10 twisted 180° in the opposite direction;
Consisting of a plurality of wing pieces 20 alternately formed along the spiral twisting surface of the spiral fixing piece 10, fixing various mats such as vegetation mats, wire netting, green mats, etc. on the surface of the incision or river embankment to prevent the outflow of earth and sand. On the other hand, it is configured to create a foundation for plants such as grass to settle.

한편, 도 3a,3b,3c는 본 발명에 따른 토사유출 방지용 매트 고정구의 제작과정을 도시한 구성도로서, 이에 대한 제작과정을 설명하기로 한다.On the other hand, Figures 3a, 3b, 3c is a block diagram showing the manufacturing process of the mat fixture for preventing soil leakage according to the present invention, it will be described in the manufacturing process.

먼저, 가로의 길이가 짧고, 세로의 길이가 길게 형성되며, 자체 탄성력이 구비된 박판의 금속띠로 이루어진 평철을 준비한 다음, 평철의 하단부를 뾰쪽하게 가공하여 첨단부(12)를 형성하게 된다(도 3a 참조).First, the length of the horizontal is short, the length of the vertical is formed long, and a flat iron made of a thin metal strip with its own elastic force is prepared, and then the lower end of the flat iron is sharply processed to form the tip 12 (FIG. See 3a).

그 다음으로 세로의 정중앙을 중심으로 양단으로 경사지고 상호 엇갈리게 절개하여 다수의 날개편(20)을 형성하게 된다(도 3b 참조).Next, a plurality of wing pieces 20 are formed by being inclined at both ends and cross-cutting each other around the center of the vertical (refer to FIG. 3B).

이러한 상태에서 중앙 영역을 중심으로 상하부를 상호 반대 방향으로 180°로 비틀게 된다. 그러면, 평철이 중앙 영역을 중심으로 비틀어지면서 비틀어진 경사면을 따라 날개편(20)이 방사상으로 벌어지면서 평면에서 보면 도 2와 같은 형상으로 형성된다(도 3c 참조).In this state, the upper and lower parts of the center region are twisted 180° in opposite directions. Then, as the flat iron is twisted around the central region, the wing piece 20 is radially spread along the twisted inclined surface and is formed in a shape as shown in FIG. 2 when viewed from a plane (see FIG. 3C).

한편, 도 4를 참조로 토사유출 방지용 매트 고정구에 대한 사용상태를 설명하기로 한다.On the other hand, with reference to Figure 4 will be described the state of use for the mat fixture for preventing soil leakage.

먼저, 절개지 또는 하천 제방 등의 법면 등에 식생매트, 철망, 녹생매트 등의 매트(1)를 안정되게 올려놓게 된다.First, a mat 1 such as a vegetation mat, a wire mesh, or a green mat is stably placed on a legal surface such as an incision or river embankment.

그 다음으로 미도시된 전동드릴에 나선형고정편(10)을 결합시킨 다음, 나선형고정편(10)의 첨단부(12)를 매트(1)에 상부에 박은 후, 공구를 회전시키면 나선형고정편(10)의 첨단부(12)가 매트(1)를 통과하여 나선형고정편(10)과 날개편(20)이 드릴 날과 같은 작용을 하게 됨에 따라 적은 힘으로도 용이하게 땅 속에 박혀 고정된다.Next, the spiral fixing piece 10 is coupled to an electric drill not shown, and then the upper end 12 of the spiral fixing piece 10 is put on the mat 1, and when the tool is rotated, the spiral fixing piece is rotated. As the tip portion 12 of (10) passes through the mat (1), the spiral fixing piece (10) and the wing piece (20) act like a drill bit, and are easily fixed into the ground with little force. .

이때, 땅속에 자갈이나 암석이 있는 경우에도 나선형고정편(10)이 좌굴을 일으키지 않고 박히게 된다. 이렇게 땅 속에 삽입된 나선형고정편은 방사형으로 형성된 날개편(20)이 나무의 뿌리처럼 지지하는 형태로 되어 강력한 지지력을 형성하게 되며, 더욱이 날개편(20)을 뽑으려고 하는 외부의 힘이 작용할 경우, 날개편(20)의 상부에 위치한 흙더미가 저항체로 작용하여 상부로 뽑히는 것을 방지하게 된다.At this time, even when there is gravel or rock in the ground, the spiral fixing piece 10 is struck without causing buckling. In this way, the spiral fixed piece inserted into the ground is formed in a form in which the radially formed wing piece 20 supports like the root of a tree, thereby forming a strong support force, and further, when an external force acting to pull out the wing piece 20 acts , It is to prevent the pile of dirt located on the upper portion of the wing piece 20 acts as a resistor to be pulled out.

이때, 토사유출 방지용 매트 고정구는 현장 등에서 전동드릴의 사용이 힘들경우에는 수동으로 사용 가능하게 된다. 즉, 현장에서 파이프 등으로 제작하여 나선형고정편(10) 상부를 안정되게 결합시킨 다음, 이를 사용자의 힘으로 매트(1)에 상부에 박은 후, 회전시키면 나선형고정편(10)의 첨단부(12)가 매트(1)를 통과하여 나선형고정편(10)과 날개편(20)이 드릴 날과 같은 작용을 하게 됨에 따라 적은 힘으로도 용이하게 땅 속에 박히게 되어 매트를 고정시키게 된다.At this time, the mat fixture for preventing soil leakage can be used manually when it is difficult to use an electric drill in the field. That is, the pipe is made of a pipe or the like to stably couple the upper portion of the spiral fixation piece 10, and then put it on the mat 1 with the user's force and rotate it to rotate the tip of the spiral fixation piece 10 ( 12) As the spiral fixing piece 10 and the wing piece 20 pass through the mat 1 and act like a drill bit, they are easily embedded in the ground with little force to fix the mat.
