Description

합성수지제 양면코러게이트관Double-coated corrugated pipe made of synthetic resin

제 1(a)도, 제 1(b)도는 본 발명의 일부 절개사시도.1 (a) and 1 (b) are partial cutaway perspective views of the present invention.

제 2(a)도, 제 2(b)도는 본 발명의 다른 실시예에 대한 요부확대 단면도.2 (a) and 2 (b) are enlarged cross-sectional views of main parts of another embodiment of the present invention.

제 3(a)도, 제 3(b)도는 본 발명의 또다른 실시예에 대한 요부확대 단면도.3 (a) and 3 (b) are enlarged cross-sectional views of a main part of still another embodiment of the present invention.

본 발명은 합성수지게 관체의 내외주면에 나선상으로 권회되어 돌출되게 힘받이리브를 형성한 것을 특징으로 하는 양면코러케이트관에 관한 것으로 내압강도(耐壓强度)가 높으면서도 비교적 가요성이 풍부하고 또한 대구경관체를 염가로 양산할 수 있을뿐만 아니라 특히 내압강도를 크게 요구하는 여러가지의 용도에 적합하게 예를들어 도로, 철도등의 조성지의 배수나 농지의 급배수 또는 공장의 급배수에 적합한 합성수지제관을 제공하는 것을 목적으로 한다.The present invention relates to a double-sided corrugated pipe formed by spirally wound and protruding spirally on the inner and outer circumferential surfaces of a synthetic resin tube, and has high pressure strength and is relatively flexible. In addition to mass production of large-area landscapes, synthetic resin pipes suitable for drainage of construction sites such as roads and railways, farmland drainage, or plant drainage are particularly suitable for various applications requiring large pressure resistance. It aims to provide.

종래의 내외양면이 스트레이트로 평활하게 되어있는 합성수제제관체의 내압력을 보강하기 위한여 관체외주면에 돌출되게 나선상으로 권회시켜 힘받이를 형성하여 왔던 것이다. 근자에 와서는 합성수지재질 및 그성형기술의 급속한 발달로 대구경관체를 생산하게 되었으나, 합성수지제관체가 대구경화하는 것에 따라 그 내압강도가 문제되어 이 내압강도를 보강하는 수단으로 관자체의 두께를 두껍게하거나 관체의 외주면에 돌출되게 형성하는 보강리브를 크게 또는 그 돌출리브에 강도 높은 심재를 매설하여 왔다. 그러나 이와같은 합성수지제관이라 할지라도 외부충격력이 극심한 도로와 같은 지하에 매설하는 경우는 그 내압강도가 약하여 매설관이 파손되어 관체를 교체하여야 하는데 따르는 도로면의 보수등 많은 비용을 허실하게 되는 것이었다.In order to reinforce the internal pressure of the synthetic handmade pipe body in which the conventional inner and outer surfaces are smooth in a straight line, it has been wound in a spiral so as to protrude on the outer circumferential surface of the tube body to form a force receiver. In recent years, due to the rapid development of synthetic resin materials and molding technology, large diameter pipes have been produced. However, as the size of synthetic resin pipes increases, the pressure resistance is problematic. Reinforcing ribs formed to protrude on the outer circumferential surface of the tubular body have been buried in large or high-strength cores. However, even in the case of such synthetic resin pipes, when they are buried underground, such as roads with extreme external impacts, the pressure resistance is weak, and the cost of repairing the road surface due to the damage of the buried pipes must be replaced.

본 발명은 상기한 바와같은 문제점을 시정하기 위하여 제안되는 것으로, 첨부도면에 의하여 발명의 내용을 상세히 설명하면 다음과 같다.The present invention is proposed to correct the problems as described above, the contents of the invention by the accompanying drawings in detail as follows.

제 1(a)도, 제 1(b)도는 본 발명의 양면코러게이트관(1)에 관한 것으로서 이는 예를들어 포리에치렌이나 포리프로피렌등의 포리에레핀계, PVC 등의 합성수지재료로서 관벽체(2)의 내외주면에 나선상에 권회되어 돌출되는 외부리브(3a)와 내부리브(3b)를 형성한 것이다. (a)도는 외부리브(3a)와 내부리브(3b)가 겹쳐있기 때문에 관벽체(2)의 가용성이 가장좋고 양리브(3a)(3b)는 최대한의 내압강도를 발휘하게 된다. (b)도는 관벽체(2)의 내외주면에 나선상으로 권회되어 돌출되는 외부리브(3a)와 내부리브(3b)가 서로 어긋나 위치하도록 형성한 것이다. 양 리브(3a)(3b)가 서로 어긋나 위치하고있어 관벽체(2)에 가해지는 내외측의 압력을 균일하게 받게된다.1 (a) and 1 (b) are related to the double-coated corrugated pipe 1 of the present invention, which is, for example, a synthetic resin material such as polyetherene-based resins such as polyethylene or polypropylene, and PVC. The outer ribs 3a and the inner ribs 3b are formed on the inner and outer circumferential surfaces of the tube wall 2 to be spirally wound and protrude. (a) shows that the outer ribs 3a and inner ribs 3b overlap, so that the pipe wall 2 has the highest solubility and both ribs 3a and 3b exhibit the maximum pressure resistance. (b) is formed so that the outer rib 3a and the inner rib 3b which are wound and protruded spirally on the inner and outer peripheral surfaces of the pipe wall 2 may be offset from each other. Both ribs 3a and 3b are shifted from each other, so that the inner and outer pressures applied to the tube wall 2 are uniformly received.

제 1 도에 도시한 본 발명의 양면 코러게이트관(1)의 실시에 있어서, 내외리브(3a)(3b) 및 그 구멍(4)의 크기나 형태의 변형을 제한하지 아니한다.In the implementation of the double-sided corrugated pipe 1 of the present invention shown in FIG. 1, modifications of the size and shape of the inner and outer ribs 3a and 3b and the holes 4 are not limited.

제 2 도는 제 1 도에 의하여 설명한 것과 동일하게 구성된 것으로, 관벽체(2)의 내외주면에 나선상으로 권회되어 돌출되는 내외리브(3a)(3b)들의 사이사이에 통체리브(3c)를 혼합적으로 배치하여되는 것으로서 통체리브(3c)는 (a)도에서 보는 바와같이 관벽체(2)의 내외주면에 지그재그로 배치되는 것이나, 예를드러 내측리브(3a) 전부를 또는 외측리브(3b) 전부를 각각 통체리브(3c)로 실시하여도 내압강도는 증대되는 것이다. 또한 (b)도와는 반대로 통체리브(3c)를 실시하여도 그 내압강도는 증대된다.FIG. 2 is configured in the same manner as described in FIG. 1, and the cylindrical ribs 3c are mixed between the inner and outer ribs 3a and 3b which are spirally wound and protruded on the inner and outer peripheral surfaces of the tube wall 2. As shown in (a), the cylindrical ribs 3c are arranged in a zigzag pattern on the inner and outer circumferential surfaces of the tube wall 2, for example, the entire inner ribs 3a or the outer ribs 3b. Even if the whole is implemented by the cylindrical ribs 3c, the breakdown strength is increased. In contrast to (b), even when the cylindrical rib 3c is provided, its breakdown strength is increased.

제 2 도에 도시한 본 발명의 양면 코러게이트관(1)의 실시에 있어서, 통체리브(3c)에 강도를 보강하기 위한 경심재의 매설을 제한하지 아니한다.In the implementation of the double-sided corrugated pipe 1 of the present invention shown in FIG. 2, the embedding of the hard core material for reinforcing the strength to the cylindrical rib 3c is not limited.

제 3 도에 도시한 양면코러게이트관(1)도 제 1 도의 설명에서와 같이 구성되는 것이나, 관벽체(2)의 내외주면에 나선상으로 권회하여 돌출되는 내외리브(3a)(3b)들 전부를 제 2 도에서의 통체리브(3c)로 형성하여 되는 것으로, 이 양면코러게이트관(1)은 본 발명에서 가장 우수한 내압강도를 기대할 수 있는 것이다. 이 통체리브(3c)에 적절한 보강심재를 매설하면 더욱 그 강도를 증대시킬 수 있다.The double-sided corrugated pipe 1 shown in FIG. 3 is also configured as in the description of FIG. 1, but all of the inner and outer ribs 3a and 3b which are wound around the inner and outer circumferential surfaces of the tube wall 2 and protrude in a spiral manner. It is formed by the cylindrical rib 3c in FIG. 2, and this double-sided corrugated pipe 1 can expect the best breakdown strength in the present invention. When the appropriate reinforcing core material is embedded in the cylindrical rib 3c, the strength can be further increased.

본 발명은 이상 설명되는 바와같이 구성되는 양면 코러게이트관이르모, 종래에 합성수지로 되는 어느 지하매설관에 비하여 구조적으로 강하에 되어 있을 뿐만 아니라 내압강도와 가용성을 적절하게 변화시켜 각종용도에 따르는 지하매설관을 제공하는 효과를 제공하는 것이다.The present invention is not only structurally lower than the double-sided corrugated tube irmo, which is constructed as described above, and conventional underground pipes made of synthetic resin, but also according to various uses by appropriately changing the pressure resistance and solubility. It is to provide the effect of providing a buried pipe.
