본 발명은 지반의 활동파괴 등으로 인하여 지반이 약한 지역이나 천재지변으로 인한 축대 붕괴지역 및 토목공사등으로 인하여 발생되는 경사이완부의 축조공사 및 보수공사를 더욱 견고하고 안전하게 시공설치 할 수 있도록 하기 위하여 제안된 식생보강토옹벽의 시공법 및 그 구조물에 관한 것으로, 탈수성 및 내습성이 양호하고 인장응력이 강력한 보강용 토목섬유매트와, 흙의 흘러내림을 방지하고 물빠짐이 원활한 부직포매트 및 성토흙을 순차적으로 적층시키고, 그 전면부에 폴리에스터망을 부착하여 다수의 앵커핀으로 고정시킨 다음, 폴리에스터망의 전면부에는 관상수의 씨앗과 유기질 비료를 혼합시킨 식생보강토를 드라이브타입으로 주사압착하면서 시공 설치하여 줌으로써 보강용 토목섬유매트와 부직포, 폴리에스터망, 앵커핀 및 유기질 식생보강토의 결합구조에 의하여 성토흙(40)의 인장응력과 탈수 및 내습기능을 발휘하면서 폴리에스터망의 전면부에 압착하는 유기질 식생보강토가 폴리에스터망을 매체로하여 전면부의 성토흙과 토착 효과를 증대시킬 수 있으며, 내,외부토압에도 무너지는 일이 없이 축조상태를 더욱 견고하고 안전하게 유지할 수 있도록 하며, 경사이완부에 성토된 평면부의 활용면적을 넓힐 수 있으며 또한 초목이나 관상수목등의 씨앗발아 및 그 생장을 촉진시킬 수 있도록 함으로써 시공지역의 환경미화는 물론 보수공사의 효율성 및 경제성을 높일 수 있도록 한 것이다.The present invention in order to be able to install more firmly and safely the construction and repair work of the slope loosening section caused by the collapsed area and civil engineering work due to the weak ground or natural disasters due to the destruction of the ground, etc. The present invention relates to a method for constructing a vegetation-reinforced soil retaining wall and its structure, and includes a reinforcing geotextile mat having good dehydration and moisture resistance and strong tensile stress, a non-woven fabric mat and a soil soil which prevents the flow of soil and smooths water drainage. Lay out sequentially, attach the polyester net to the front side and fix it with a number of anchor pins, and then install the vegetation reinforcement soil mixed with seeds of organic water and organic fertilizer on the front part of the polyester net while driving and compressing it with a drive type. Reinforcement geotextile mat and nonwoven fabric, polyester net, anchor pin and organic The organic vegetation reinforced soil, which is pressed onto the front surface of the polyester network while exerting the tensile stress, dehydration and moisture resistance of the sandy soil 40 by the combined structure of the vegetation reinforced soil, is made up of polyester soil and the indigenous effect on the front surface. It is possible to increase the size, to maintain the construction state more firmly and safely without collapsing to internal and external earth pressure, and to increase the utilization area of the flat part that is inclined to the loosening part, and also to seeds of plants and ornamental trees. By promoting germination and its growth, it is possible to enhance the efficiency and economic efficiency of the renovation work as well as the environmental beautification of the construction area.

종래에 통수성시이트나 폴리에스터매트를 경사구간의 공사면에 평면상태로깔고 성토흙을 덮어 쌓아 올리는 시공 설치 작업으로 행하여지고 있는 구조에 있어서는 통수성시이트나 폴리에스터매트가 공사면에 평면상태로만 깔아지게 되므로 성토흙을 쌓아올리는 전단부로 성토흙이 흘러내리게 되어 전단부로 흘러내리는 흙을 다시 퍼올리면서 성토작업을 하여야 되는 번거러운 결점이 있었다.Conventionally, in a structure in which a water-permeable sheet or polyester mat is laid in a flat state on a construction surface of an inclined section and covered with soil, the water-permeable sheet or polyester mat is in a flat state only on the construction surface. Since it is laid, the soil flows down to the front end portion of the piled up soil, which causes cumbersome defects to be carried out while spreading the soil flowing down to the front end portion.

이와 같은 결점을 해결하기 위하여 공사면에 평면상태로 깔아지는 폴리에스터매트의 전후방부를 연장하여 형성되어지는 연장매트로서 전후방의 성토를 덮어씌워 줌으로써 공사면의 전후방으로 형성되어지게 되는 힘받이 두둑층의 성토층과 함께 한단(段)의 쟁반형 성토층이 형성되어 지도록 시공 설치한 다음 전면부로 형성되어 지게되는 호형굴곡 형상의 전면주벽으로 텍솔을 가압 착접하여 시공 설치 작업을 완료하였으나, 이는 폴리에스터매트에 의하여 쟁반형 성토층의 인장응력의 효과는 있으나 탈수 및 내습성이 미약하여 비가 많이 오게되면 배수가 원활하지 못하여 호형굴곡형상의 전면주벽에 착접된 텍솔이 쉽게 탈이되었으며, 공사면의 상면부에 다소간의 압력이 가하여지게 되더라도 성토층의 축조상태가 변형되어 쉽게 붕괴되는 결점이 있었다.In order to solve this drawback, it is an extension mat formed by extending the front and rear parts of the polyester mat laid in a flat state on the construction surface. The installation was completed so that a single tray-type fill layer was formed along with the fill layer, and then the texol was press-welded to the arc of the front circumferential wall which is formed as a front part. The effect of tensile stress on the tray-type fill layer is due to the weakness of dehydration and moisture resistance. However, when the rain is heavy, the drainage is not smooth and the texol contacted to the circumferential wall of the arc-shaped curve is easily detached. Even if a little pressure is applied to the defect, the buildup state of the fill layer is deformed and collapses easily. there was.

본 발명은 종래의 제반 결점을 해소하기 위하여 성토흙이 보강용 토목섬유매트와 부직포, 폴리에스터망, 앵커핀 및 유기질 식생보강토의 결합구조에 의하여 인장응력과 탈수 및 내습효과는 물론 폴리에스터망의 전면부에 압착하는 유기질 식생보강토가 폴리에스터망을 매체로하여 전면부의 성토흙과 토착 효과를 증대시킬 수있도록 하며, 내외부토압에도 무너지는 일이 없이 축조상태를 더욱 견고하고 안전하게 유지할 수 있도록 하며, 성토된 평면부의 활용 면적을 높일 수 있으며, 또한 화초나 관상수목등의 씨앗발아 및 그 생장을 촉진시킬 수 있도록 함으로써 시공지역의 환경미화는 물론 보수공사의 효율성 및 경제성을 높일 수 있도록 한 식생보강토 옹벽 시공법 및 그 구조물을 제공함에 목적이 있다.In order to solve the conventional drawbacks, the present invention provides a tensile stress, dehydration and moisture resistance effect as well as the effect of tensile stress, dehydration and moisture resistance by the combination structure of earth soil reinforcement geotextile mat and nonwoven fabric, polyester network, anchor pin and organic vegetation reinforcement soil. Organic vegetation-reinforced soil compressed on the front side can increase the indigenous effect with the soil and soil on the front side by using polyester net, and it can maintain the construction state more firmly and securely without collapsing to internal and external earth pressure. Reinforcing wall of vegetation reinforced soil, which can increase the utilization area of the flattened section, and also promote seed germination and growth of plants and ornamental trees.
