Description
본 발명은 배수로관용으로 널리 사용하는 배수로관용 고강도 나선관(이하에서는 고강도 나선관이라 칭한다)에 관한 것이다The present invention relates to a high strength spiral tube (hereinafter referred to as a high strength spiral tube) widely used for drainage pipes.
일반적으로 고강도 나선관을 지중 매몰시켜 배수로관용으로 장기간 사용하는 경우, 고강도 나선관은 제품의 구조상 중공구와 I빔 구조로 구분이 되는바, 외토압 하중이나 지역적으로 연약 지반이나 간혹 공사 품셈을 정확히 수행하지 않는 공사 지역에서 편중 하중이나 지반침하 등으로 나선권회로 구성된 나선관에서 중공구가 형성된 부위가 취약한 구조로 파손되는 문제점이 있어서 고강도 나선관의 사용범위가 넓지 못하는 문제점이 있었다.In general, when a high strength spiral tube is buried under the ground and used for a long time as a drainage pipe, the high strength spiral tube is divided into a hollow sphere and an I-beam structure in terms of product structure. There is a problem in that the use of high-strength spiral tube is not wide because there is a problem that the hollow sphere is formed in the spiral tube formed by the spiral winding due to unbalanced load or ground subsidence.
그래서 상기와 같은 문제점을 보완하기 위하여 양측벽면으로 서로 나선권회로 일체화시켜 준 중공구에 경질수지대 또는 경질 발포체 또는 보강 수지관 등을 충만 시켜준 제품이 제공되었다Thus, in order to solve the above problems, a product was provided in which the hollow spheres integrated with the spiral windings on both side walls were filled with a hard resin zone, a rigid foam, or a reinforced resin tube.
그러나 상기 제공된 고강도 나선관은 나선관을 길이 방향으로 구조를 살펴볼 경우 배수로관이 (300m/m 이하인 소형 규격에서는 외토압 등이 양호하나800m/m 이상인 중,대 규격에서는 규격의 크기에 비교하여 견고성 및 외토압 보강이 상대적으로 취약하므로 고강도 나선관의 수요 확대 및 견고성 제공을 위하여 보다 더 고강도 구조의 제품이 요구되는 현실이다.However, the high-strength spiral pipe provided above has a drainage pipe when the spiral pipe is constructed in the longitudinal direction. In the small size of 300m / m or less, the external pressure is good. In the medium and large sizes of more than 800m / m, the strength and external pressure reinforcement is relatively weak compared to the size of the standard, so the product of a higher strength structure is required to expand the demand and provide the strength of the high strength spiral tube.
본 발명은 상기 제시된 문제점을 보강하기 위하여 제공되는 발명으로서 종래의 나선관에서 중공구와 양측벽면으로 일체화되는 I빔 구조 부위의 고강도의 견고성이 제공되는 부위의 평균화를 위하여 중공구와 양측벽면이나 접합대로 일체화되는 나선관을 2층 및 3층 구조로 동일 나선관 규격의 기존 두께와 동일 두께로 2∼3등분시켜 서로 상.하측면으로 서로 중첩시켜서 기존 동일 규격의 나선관 두께와 동일하게 제공되는 보강 나선관에다 +형 보강대 및 융착대 등으로 각층의 중공구에 충진시켜 보강되는 중공구 부위의 취약점을 보완하기 위한 발명이다.The present invention is an invention provided to reinforce the above-mentioned problems and integrated into the hollow sphere and both side walls or joints for averaging the region provided with high strength and rigidity of the I-beam structure portion integrated into the hollow sphere and both side walls in the conventional spiral tube. Reinforced helix provided with the same thickness of the existing spiral pipe by overlapping each other in upper and lower sides by dividing the spiral pipe into two and three layers with the same thickness as the existing thickness of the same spiral pipe standard It is an invention to compensate for the weak point of the hollow sphere part which is filled by reinforcing the hollow sphere of each layer with a + type reinforcing rod and a fusion rod in the pipe.
