Description
본 발명은 해안이나 강변, 간석지(干潟地) 및 늪지대 등의 점성토로 이루어진 연약지반(7)의 내부에 함유되어 있는 수분(물)을 더욱 효과적으로 탈수시킬 수 있도록 하기 위하여 제안된 부직포를 둘러 씌운 엠보형 보드드레인을 이용한 연약지반의 탈수 촉진공법 및 엠보형 보드드레인에 관한 것으로,The present invention is embossed covering the nonwoven fabric proposed in order to more effectively dehydrate the water (water) contained in the soft ground (7) made of viscous soil, such as coastal, riverside, tideland and swamps Dehydration promoting method and embossed board drain of soft ground using a type board drain,
부직포를 둘러 씌운 좌,우엠보형 보드드레인의 구조를 판형심재의 좌,우로 엠보형의 돌출부에 의하여 좌,우로 관통되는 통수구멍을 뚫은 판형심재의 둘레부에 부직포를 둘러 씌운 상태로 부착시켜 부직포를 둘러 씌운 좌,우엠보형 보드드레인을 형성하며, 이와 같이 형성시킨 부직포를 둘러 씌운 좌,우엠보형 보드드레인을 점성토 연약지반의 표면부로 돌출되도록 수직드레인으로 심설하여 배수층을 형성하며, 배수층에는 부직포를 둘러 씌워 부착시킨 구조의 유공주름관형을 수평배수관이 되도록 시공설치 한 다음, 성토흙을 적층시킴으로서, 본 발명의 시공이 완료되는 것으로서 연약지반에 함유되고 있는 물(수분)이 수직드레인으로 시공설치한 부직포를 둘러씌운 좌,우엠보형 보드드레인의 수직통로로 유입되어 유공주름배수관형 수평드레인을 통하여 더욱 효율적으로 배수되도록 한 것이다.Non-woven fabric is attached to the circumference of the plate core with the left and right embossed board drains covered by the nonwoven fabric in the periphery of the core through which the left and right embossed protrusions penetrate the left and right. A left and right embossed board drain is formed around the nonwoven fabric. A left and right embossed board drain covering the nonwoven fabric thus formed is formed by vertical drain so as to protrude to the surface portion of the soft clay, and a drainage layer is formed. The installation of the perforated corrugated pipe structure of the structure attached to the nonwoven fabric to be a horizontal drainage pipe, and then by laying the ground soil, the construction of the present invention is completed, the water (moisture) contained in the soft ground is constructed as a vertical drain It flows into the vertical passages of the left and right embossed board drains covering the installed nonwoven fabrics, And it would have to be more efficient drainage.
종래에 좌,우로 밀폐된 구형파형()심재의 좌우로 직조천이나 필터를 부착한 구조의 구형파형심재의 드레인과 금속사나 합성수지사를 심사로 하여 코일형 판상이 되도록 형성하여 코일형 판상의 둘레부에 직조천이나 부직포를 둘러 씌워 부착시킨 구조의 코일형 판상의 드레인이 있었다.Conventionally, left and right sealed square waves ( ) Wires of square wave cores with a woven cloth or filter attached to the left and right of the core are formed into a coiled plate with a screen of metal yarn or synthetic resin, and the woven cloth or nonwoven fabric is wrapped around the coiled plate. There was a coil-shaped drain of the structure.
이와 같이 종래에 실시되고 있는 구형파형심재의 드레인은 시공시에 지중의 토압이나 공사중의 충격 또는 사용(작용)중에 지반의 침하에 의하여 직조편이나 부직포가 구형파형심재의 굴곡진 요입부의 내부로 밀려 들어 가게 되어 수직 탈수 통로가 좁아지게 되며, 심한 경우는 직조천이나 부직포가 손상되거나 굴곡진 요입부가 확개되어 굴곡진 요입부의 내부로 흙이 밀려들어 가게 되어 수직통로가 막혀버리게 됨에 따라 수직 탈수통로의 기능이 상실되어 배수(탈수)기능을 발휘하지 못하게 되는 결점이 있었으며, 코일형판상의 드레인에 있어서는 시공시에 지중의 토압이 코일형판상의 드레인의 좌,우를 가압함에 따라 코일형의 형상에 의하여 형성되는 수직폭의 거리가 좁혀지거나 사용(작용)시에 지반의 침하로 인하여 코일형판상의 형체가 변형되어 탈수 기능이 저하되는 결점이 있었다.As described above, the drainage of the conventional rectangular corrugated core material is pushed into the curved concave part of the rectangular corrugated core by the soil earth pressure during construction, the impact during construction, or the ground subsidence during use. The vertical dewatering passage narrows, and in severe cases, the woven cloth or the nonwoven fabric is damaged or the curved concave indentation is enlarged, and soil is pushed into the curved concave indent, causing the vertical passage to be blocked. There was a defect that the function is lost and the drainage (dehydration) function is not exerted. In the drain on the coil plate, the earth pressure in the ground presses the left and right of the drain on the coil plate to form the coil shape. The shape of the coil plate is deformed due to the narrowing of the vertical width or the settlement of the ground during use. There was a defect that the dewatering function is reduced.
또한, 출원인의 선출원 발명 1998년 06월 08일 특허출원 제21031호(등록일자:2000년04월18일 특허 제261407호)에 있어서는 연약지반의 탈수 촉진용 부직포를 피착시킨 중공보드드레인으로서 전후면 주벽(4)(5)의 중앙부에 구형 및 장방형의 각 수직칸막이(7)(7a)(7b)(7c)이와 연통되도록 배수안내터짐부(8) 및 배수안내구멍(8a)(8b)을 형성한 구조의 몸체(2)(2a)(2b)의 둘레부에 부직포(3)를 둘러 씌워 피착함으로서 구형 및 장방형의 수직칸막이(7)가 구형과 장방형 및 원통형의 각 수직탈수통로(10)(10a)(10b)가 형성되도록 구성하였다.In addition, the patent application No. 21031 (registration date: Apr. 18, 2000, Patent No. 261407) on June 08, 1998 is a hollow board drain coated with a nonwoven fabric for promoting dehydration of soft ground. In the center of the circumferential wall (4) (5), the drain guide gutter (8) and the drain guide hole (8a) (8b) are connected to each of the rectangular and rectangular vertical partitions (7) (7a) (7b) (7c). Spherical and rectangular vertical partitions 7 are spherical, rectangular, and cylindrical vertical dewatering passages 10 by covering the nonwoven fabric 3 around the bodies 2, 2a, and 2b of the formed structure. It was comprised so that (10a) (10b) may be formed.
이와 같이 구성된 중공보드드레인(1)(1a)(1b)에 있어서는 시공설치시에 토압이나 공사중의 충격 또는 설치 후에 지반이 침하되더라도 부직포가 손상되는 일이 없으며, 중공보드드레인(1)(1a)(1b)이 변형되는 일이 없이 견고하고 안전한 상태를 유지할 수 있으나, 배수안내터짐부 및 배수안내구멍(8)(8a)(8b)을 형성하여 장방형 및 원통형의 각 수직탈수통로(10)(10a)(10b)와 연통시킨 구형 및 장방형의 각 수직칸막이(7)(7a)(7b)(7c)를 형성하는 전후면주벽(4)(5)에 의해 전후면적이 넓어지며(90%이상), 더욱이 전후면주벽(4)(5)을 부직포(3)로 둘러 씌워 피착시켰으므로 수직탈수통로(10)(10a)와 연통되는 배수안내터짐부 및 배수안내구멍(8)(8a)(8b)에 의한 수분(물)의 유입 기능이 저하되는 결점이 있었다.In the hollow board drain (1) (1a) (1b) configured in this way, the nonwoven fabric is not damaged even if the earth pressure or the impact during construction or the ground subsides after installation, and the hollow board drain (1) (1a) (1b) can maintain a solid and safe state without being deformed, but each of the rectangular and cylindrical vertical dewatering passages (10) by forming the drain guide projection and the drain guide holes (8) (8a) (8b) ( The front and rear circumferences are widened (90% or more) by the front and back circumferential walls 4 and 5, which form respective rectangular and rectangular vertical partitions 7, 7a, 7b and 7c in communication with 10a and 10b. In addition, since the front and rear peripheral walls (4) and (5) were covered with a nonwoven fabric (3) and deposited, the drainage guide rupture portion and the drainage guide hole (8) (8a) (which communicate with the vertical dewatering passage (10) (10a) ( 8b) had the disadvantage that the inflow function of water (water) is reduced.
특히, 중공보드드레인(1)(1a)(1b)을 형성하는 배수안내터짐부 및 배수안내구멍(8)(8a)(8b)와 장방형 및 원통형의 각 배수탈수통로(10)(10a)(10b)와 구형 및 장방형의 각 수직칸막이(7)(7a)(7b)(7c)를 형성하는 각 중공보드드레인의 몸체(2)(2a)(2b)의 구조가 복잡하여 제작공정의 복잡성 및 제품의 원료가 많이 소요됨에 따라서, 제작비용이 많이 들게되어 부가가치를 높일 수 없는 결점이 있었다.In particular, the drainage guide projections and drainage guide holes 8, 8a and 8b forming the hollow board drains 1, 1a and 1b, and the rectangular and cylindrical respective drainage dewatering passages 10 and 10a ( 10b) and the structure of the body 2, 2a, 2b of each hollow board drain forming the rectangular and rectangular vertical partitions 7, 7a, 7b, and 7c. As the raw material of the product is consumed a lot, the manufacturing cost is high and there is a drawback that the added value cannot be increased.
이와 같은 구조결합으로 된 각 드레인은 제품의 구조가 복잡하고 부피가 커지게 되어 시공 설치작업이 복잡하여지게 되는 결점이 있었다.Each drain of the structural combination has a defect in that the construction of the product is complicated and bulky, which makes the installation work complicated.
이와 같은 본 발명은 상기 종래의 제반 결점을 적게 하기 위하여 판형 심재를 수직면으로 하여 좌,우로 연통되는 탈수통로와 관통구멍을 뚫은 다수의 엠보형돌출부를 형성하는 구조를 단일공정에 의하여 간단히 제작하여 둘레부를 부직포로서 둘러 씌워 부착되도록 결합시킨 구성의 부피가 적은 경량의 부직포를 둘러씌운 좌,우 엠보형 보드드레인을 수직드레인으로 하여 점성토 연약지반의 지중으로 시공설치함으로써, 시공설치작업을 간편하고 용이하게 할 수 있도록 하며, 시공설치 작업시에 토압이나 충격에 의해 부직포가 손상되는 일이 없도록 하며, 지반이 침하되더라도 좌,우, 연통되는 탈수통로와 관통구멍을 뚫은 다수의 엠보형 돌출부를 형성한 판형심재가 변형되는 일이 없도록 하며, 연약지반에 함유되어 있는 수분(물)이 상기 엠보형 보드드레인의 내부로 유입되는 탈수가 관통구멍을 통하여 좌,우로 유통하면서 탈수 촉진을 더욱 증진시킬 수 있도록 함에 목적이 있다.In order to reduce the above-mentioned drawbacks, the present invention simply manufactures a structure for forming a plurality of embossed protrusions through which a dehydration passage communicating with the left and right and a through hole is made by using a plate-shaped core as a vertical plane. The installation of the left and right embossed board drains covered with a small volume of light nonwoven fabrics, which are combined to cover the parts as non-woven fabrics, is installed as the vertical drains, making the installation easier and easier. To prevent damage to the nonwoven fabric due to earth pressure or impact during installation and installation work, and the plate shape is formed with a number of embossed projections through which the left, right, communicating dehydration passages and through holes are drilled even when the ground is submerged. The core material is not deformed, and the water (water) contained in the soft ground is embossed. There are as to the dehydration from entering the inside of the drain to further promote the dehydration and facilitate left or right through the distribution through-hole object.
