Description

경사면 보호를 위한 녹화용 코어네트 시공방법{A greening core-net construction method for an incline plane protection}Greening core-net construction method for an incline plane protection

본 발명은 경사가 심한 산지의 법면에서 강우에 의한 토사의 유실과 세굴을 방지하면서 임간나지를 녹화할 수 있게 하는 경사면 보호를 위한 녹화용 코어네트를 이용한 시공방법에 관한 것이다.The present invention relates to a construction method using a greening core net for the slope protection to record the forest land while preventing the loss and sedimentation of the soil due to rainfall on the slope of the mountain slopes.

비탈진 산지의 소로 또는 등산로 등에서 흔히 발생하는 답압에 의한 세굴은 강우에 의하여 가속화되면서 물길을 형성하여 산지사면의 산사태를 유발하기도 하므로 경사면에 계단을 설치하거나 테크로드 등을 설치하고, 불가피할 경우에는 돌붙임, 돌계단, 잡석채움, 목책 등으로 토사의 유실을 방지하는 방법이 널리 사용되어 왔으나 과도한 비용이 소요된다는 문제점이 있었다.Scour due to pressure, which usually occurs in slopes or hiking trails in non-depleted mountain areas, is accelerated by rainfall, forming water paths, which can cause landslides on mountain slopes. The method of preventing the loss of soil by sticking, stone steps, rubble filling, barrier, etc. has been widely used, but there is a problem that excessive cost is required.

종래와 같은 문제점을 해결하고자 본 출원인은 공개측허 2009-0042385(2009년 04월 30일 공개)호의 도 1에 도시한 것과 같이 자연부식이 가능한 '천연섬유부재를 이용하여 산지법면의 토사유실과 세굴을 방지하고 녹화할 수 있게 하는 코어네트에 있어서, 천연섬유매트를 폭방향으로 일정간격을 이격하여 돌출되게 접어 토사포집부(7)를 형성한 코어네트(3)를 법면(4)에 설치하고 앵커(5)와 와이어(6)로 지면에 고정한 후 토사포집부(7)에 토사(8)를 채우고 다짐작업 후 다짐한 토사(8) 위쪽에 돌출되는 돌출부(1)를 법면(4)의 경사면 아래쪽 방향으로 접어 토사포집부(7)의 토사(8)를 덮을 수 있도록 하여 경사면을 보호할 수 있게 한 녹화용 코어네트 설치공법을 제안한 바 있었다.In order to solve the same problem as the prior art, the applicant has disclosed that the soil loss and scour of the mountain area surface using natural fiber member, which can be naturally corroded, as shown in FIG. 1 of Publication No. 2009-0042385 (published on April 30, 2009). In the core net for preventing and recording, the core net (3) is formed on the surface (4) to fold the natural fiber mat protruded at a predetermined interval in the width direction to form the earth and sand collecting portion (7) After fixing to the ground with the anchor (5) and the wire (6) to fill the earth and sand (8) in the soil collecting part (7), the projection (1) protruding above the compacted soil (8) after compaction work inclined surface of the surface (4) There has been proposed a method for installing the core net for greening which can be folded downward to cover the soil 8 of the soil collecting part 7 so as to protect the inclined surface.

그러나 상기의 시공방법은 경사가 심하지 않은 법면에서는 토사의 보호에 대단히 유용하였으나 경사가 심한 법면에서는 경사면의 아래쪽 방향으로 접힌 토사 포집부의 개구부로 답압에 의하여 토사가 유출되면서 강우에 의하여 씻겨 내려간다는 문제점이 있다는 것을 발견하게 되었다.However, the above construction method is very useful for the protection of earth and sand on the slope where the slope is not severe, but the problem is that the soil is washed away by the rainfall as the soil is leaked by the pressure on the opening of the soil collecting section folded downward on the slope. I found it.

본 발명은 경사가 심한 산지의 법면에서도 답압 또는 강우에 의하여 토사가 유실되는 것을 방지할 수 있게 하면서 경사면에 포설된 코어네트가 쉽게 훼손되거나 변형되는 것을 방지할 수 있게 하는 수단을 제공하는 것을 목적으로 한다.An object of the present invention is to provide a means for preventing the loss of soil by the pressure or rainfall in the slopes of mountainous slopes, while preventing the core net installed on the slope to be easily damaged or deformed. do.

본 발명은 코코넛 섬유로 길게 형성한 매트를 폭 방향으로 일정한 간격으로 돌출되게 접어 주름진 형상의 토사 포집용 코어네트를 형성하고 코어네트 돌출부 사이의 토사 포집부에는 돌출부 높이의 2/3 정도가 되게 토사를 채워넣고 다져 돌출부 높이의 1/2 정도가 되게 한 후 다져진 토사 위의 돌출부는 법면의 위쪽 방향으로 접어 토사층의 표면을 답압과 강우에 의하여 유실되는 것을 방지할 수 있게 구성하여 초류 종자 등이 부착되어 성장할 수 있게 구성한다.The present invention is to fold the mat formed by the coconut fiber protruding at regular intervals in the width direction to form a corrugated soil collecting core net of the corrugated shape, the earth and sand collecting portion between the core net projections to be about 2/3 of the height of the projections After filling up and compacting it to about 1/2 of the height of the overhang, the overhang of the overlaid soil is folded in the upward direction of the surface to prevent the soil surface from being lost due to pressure and rainfall. We construct to be able to grow.

또한 토사 포집용 코어네트가 법면을 따라 흘러 내려가는 것을 방지할 수 있도록 코어네트의 가장자리에 일정한 간격으로 앵커를 설치하고 앵커 사이에는 코어네트의 토사 포집부의 바닥면을 길이방향으로 가로지르는 강선을 연결하여 코어네트를 지면에 고정한다.Also, install anchors at regular intervals on the edges of the core net to prevent the sediment collecting core net from flowing down the surface, and connect the steel wires crossing the bottom surface of the soil collecting part of the core net in the longitudinal direction between the anchors. Secure the core net to the ground.

또한 토사 포집부의 경사면 위쪽 방향으로 접혀지는 돌출부는 바닥면의 코어네트와 길이 방향으로 일정간격이 유지되게 봉제하여 돌출부가 답압 등에 의하여 표면에서 일어나거나 변형되는 것을 방지하게 하고, 돌출부의 접힌 부분의 단부에는 열팽창계수가 높은 수지 또는 금속 선을 삽입하여 돌출부의 선단이 쉽게 변형되지 않게 하면서 열에 의하여 삽입된 와이어가 팽창하면 재봉선에 의하여 양쪽이 고정되면서 가운데 부분이 부풀어 올라 포켓역할을 하면서 경사면을 따라 흘러내리는 토사를 토사 포집부로 수용할 수 있게 구성한다.In addition, the protrusions folded in the upward direction of the inclined surface of the soil collecting part are sewn to maintain a constant distance in the longitudinal direction with the core net of the bottom surface to prevent the protrusions from occurring or being deformed on the surface due to the pressing force, etc., and the ends of the folded portions of the protrusions. Insert the resin or metal wire with high coefficient of thermal expansion so that the tip of the protruding part is not easily deformed, and when the wire inserted by the heat expands, both sides are fixed by the sewing line and the center part swells up and flows down the slope while acting as a pocket. Configure the soil to be accommodated as the soil collection.

본 발명은 표면에 노출되는 토사층이 없어 경사가 심한 법면에서도 답압이나 강우에 의한 토사의 유출우려가 없으며 토사 포집부의 토사가 답압 등에 의하여 다져져 부족해질 경우에도 코어네트 위에 토사를 뿌려주면 경사면을 따라 토사가 흘러내리면서 포켓을 통하여 토사 포집부로 보충되게 하는 등 경사가 심한 법면에서의 토사유출방지와 코어네트 사후관리를 용이하게 할 수 있게 하는 효과가 있다.In the present invention, there is no soil layer exposed on the surface, so there is no fear of leakage of soil by stepping pressure or rainfall even on a slope with a severe slope, and even when the soil of the soil collecting part is shortened due to pressure, etc. As it flows down, the soil is replenished through the pockets, so that it is effective to prevent soil leakage on the slope and to facilitate core net aftercare.
