Abstract
본 고안은 옹벽 등의 지하 콘크리트 구조물의 배면(흙과 접하는 면)에 설치하는 배수판에 덧대는 보강된 부직포에 관한 것으로, 흙 속의 침출수가 잘 빠지도록 콘크리트 구조물에 설치하는 배수판의 돌기 사이로 침출수만 흐르도록 투수성 부직포를 배수판의 돌기위에 덧대어 흙은 걸러주고 침출수만 통과하도록 한 것으로서, 흙의 무게에 눌려 부직포가 늘어나거나 찢겨져서 돌기 사이를 막아 침출수의 흐름을 방해하지 못하도록 일반 투수성 부직포에 인장강도가 뛰어난 고강도 폴리에스터 등의 단독 혹은 혼합된 합성섬유사나 유리섬유 등의 천연섬유사를 격자나 능형망 형태로 직조하여 만든 그물망을 열융착 혹은 재봉질로 합지하여 이루어진 것을 특징으로 한다.
따라서, 본 고안의 보강된 부직포 부착식 배수판을 설치하면, 고강도 폴리에스터 등의 단독 혹은 혼합된 합성섬유사나 유리섬유 등의 천연섬유사 등이 갖는 특성으로 인하여 인강강도가 높아져 토압으로 인한 처짐에 저항하여 배수판 돌기 사이의 배수 공간을 충분히 확보함으로써, 배수가 잘되어 구조물의 누수를 방지하여 구조물의 내구성을 높이고, 수압에 의한 토압의 증가를 막아 구조물의 전도를 막아주는 효과가 있다.The present invention relates to a reinforced nonwoven fabric padded on a drain plate installed on the back surface (surface contacting soil) of an underground concrete structure such as a retaining wall. The permeable non-woven fabric is placed on the projection of the drainage board to filter the soil and pass only the leachate. It is characterized in that the mesh made by weaving a single or mixed synthetic fiber yarns such as high strength polyester or natural fiber yarns, such as glass fibers in the form of lattice or rhomboid net with heat fusion or sewing.
Therefore, when the reinforcing nonwoven fabric-type drainage plate of the present invention is installed, the toughness is increased due to the characteristics of the synthetic fiber yarn such as high strength polyester alone or mixed or natural fiber yarn such as glass fiber, thereby resisting sagging due to earth pressure. By securing sufficient drainage space between the drainage plate projections, the drainage is well prevented the leakage of the structure to increase the durability of the structure, there is an effect of preventing the conduction of the structure by preventing the increase of earth pressure by the water pressure.
Description
본 고안은 옹벽 등의 지하 콘크리트 구조물의 배면(흙과 접하는 면)에 설치하는, 보강된 부직포를 덧댄 일체형 배수판에 관한 것으로서
The present invention relates to a one-piece drain board with reinforced nonwoven fabric installed on the back surface (surface contacting soil) of underground concrete structures such as retaining walls.
해당 내용 없음None of the above
본래, 배수판은 흙 속의 침출수가 잘 빠지도록 콘크리트 구조물에 붙여서 설치하는 것으로서 배수판에 있는 돌기 사이로 침출수만 흐르도록 투수성 부직포를 배수판의 돌기 위에 덧대어 흙은 걸러주어 유실을 막고, 부직포를 통과한 침출수만 배수판의 돌기 사이를 따라 흘러 콘크리트 구조물 옆에 설치된 배수관을 통하여 신속히 배출하여야 하나, 부직포가 토압에 의해 늘어지거나 찢어져 흙이 배수판의 돌기 사이를 막아 침출수의 흐름을 방해하여 구조물에 누수가 발생하고, 그 영향으로 콘크리트 구조물의 내구성이 저하되며, 또한 배수되지 않은 침출수의 수압에 의해 콘크리트 구조물이 전도되는 등 큰 문제점으로 대두 된바, Originally, the drain board is installed by attaching it to the concrete structure so that the leachate in the soil is easily drained.The permeable nonwoven fabric is placed on the projection of the drain board so that only the leachate flows between the projections in the drain board, and the soil is filtered out to prevent the loss, and the leachate passed through the nonwoven fabric. The water flows between the projections of the drain plate and discharges quickly through the drain pipe installed next to the concrete structure.However, the nonwoven fabric is stretched or torn due to earth pressure, so that the soil blocks the projections of the drain plate and prevents the flow of leachate, causing leakage to the structure. As a result, the durability of the concrete structure is lowered, and the concrete structure is turned over by the hydraulic pressure of the leachate that is not drained.
전술한 과제를 해결하기 위해서, 본 고안은 일반 투수성 부직포에 인장강도가 뛰어난 폴리에스터, 유리섬유 등의 단독 혹은 혼합된 합성섬유사나 천연섬유사를 격자나 능형 형태로 직조하여 만든 그물망을 열융착 혹은 재봉질로 합지하여 이루어진 것을 배수판에 부착하는 것을 특징으로 한다.In order to solve the above problems, the present invention is heat-sealed a net made by weaving a single or mixed synthetic or natural fiber yarns such as polyester, glass fiber, etc. or natural fiber yarns with excellent tensile strength to a general permeable nonwoven fabric Or it is characterized in that attached to the drainage plate made by laminating with sewing.
이상에서 살펴본 바와 같이 본 고안의 보강된 일체형 배수판에 의하면, 보강망의 재질인 고강도 폴리에스터 등의 단독 혹은 혼합된 합성섬유사나 유리섬유 등의 천연섬유사가 갖는 특성으로 인하여 부직포의 인장강도를 높여주므로 해서 부직포의 변형을 최소화시켜 침출수만을 신속히 배출하는 배수판 본래의 기능을 다할 수 있어 콘크리트 구조물의 내구성을 높이고, 전도를 방지하는 역할을 하는 효과가 있다.As described above, according to the reinforced integral drainage plate of the present invention, the tensile strength of the nonwoven fabric is increased due to the characteristics of a single or mixed synthetic fiber yarn such as high strength polyester, which is a material of the reinforcing network, or a natural fiber yarn such as glass fiber. By minimizing the deformation of the non-woven fabric can perform the original function of the drain plate to discharge only leachate quickly has the effect of increasing the durability of the concrete structure, preventing the fall.
