Description

배수로관용 고강도 나선관{omitted}High strength spiral pipe for drainage pipe

본 발명은 합성수지제로 구성된 배수로관용 고강도 나선관에 관한 것으로서특히 경량이면서 외토압 보강이 증대되는 제품을 제공하는 고강도 나선관에 관한 것이다The present invention relates to a high-strength spiral pipe for drainage pipes made of synthetic resin, and more particularly, to a high-strength spiral pipe for providing a product that is lightweight and has increased external pressure reinforcement.

일반적으로 지하에 매설하여 하수로 및 오폐수로 등으로 사용되는 배수관의 외토압 보강을 위하여 나선관의 요부인 보강대의 구조가 지하에 매몰하여 사용 도중 외토압 하중을 받으면 양측 벽면이 좌우 길이 방향으로 굽혀지면서 나선관의 원주 방향 단면이 타원형으로 변형될 뿐만 아니라 매설후 외부에서 가해지는 압력에 쉽게 파손되며 배수관의 두께를 두껍게 할 경우에는 중량이 무거워지고 생산 원가가 상승하는 문제가 제기 되었다Generally, in order to reinforce the external pressure of drain pipe used in sewer and wastewater channel by laying underground, the reinforcement of the reinforcing pipe, which is the main part of the spiral pipe, is buried underground, and when the external pressure is applied during use, both side walls are bent in the left and right length direction. As a result, the circumferential cross section of the spiral pipe is not only deformed into elliptical shape, but also easily damaged by external pressure after embedding, and when the thickness of the drain pipe is thickened, the weight becomes heavy and the cost of production increases.

고로 상기 문제점을 보강하기 위하여 보강대 사이의 접착대의 요홈 부위에서 보강대의 중간 높이에 요홈지지대를 별도의 다이스에서 압출된 튜브로 일체화 시켜 구성된 제품이 제공되었으나 이는 별도의 튜브를 압출시켜 제조공정의 성형기에서 외접시켜 요홈에 지지대가 일체된 제품은 지중 매몰시켜 장기간 사용하는 경우 제조 공정에서 접착대를 융착시켜 형성된 요홈부위와 보강대 사이의 융착부위가 나선관을 지중매몰시켜 사용도중 집충하중으로 변형이 될 경우 융착부위가 박리되는 경우가 높아서 압출기에서 일체로 압출되어 지지대가 형성되는 제품의 제공이 요망되는 현실이다Therefore, in order to reinforce the above problem, the product was provided by integrating the groove support at the middle height of the reinforcement in the groove portion of the bond between the reinforcing rods by the tube extruded from a separate die, but this was extruded in a molding machine of the manufacturing process. In the case of long-term use of the product in which the support is integrated in the groove by undergrounding, if the fusion site between the groove and the reinforcing bar formed by fusion of the adhesive bar in the manufacturing process is buried in the spiral tube and transformed into a collecting load during use Since the fusion site is often peeled off, it is desirable to provide a product in which the support is formed by being integrally extruded from the extruder.

본 발명은 종래의 나선관에서 보강대 및 접착대 부위의 취약점을 보강대 구조를 개선하고 접착대 부위에 집중 외토압이 가해지는 경우 박리되는 문제점 해결과 가벼우면서도 외토압에 대한 내구력이 증대되도록 하는데 그 기술적 과제가 있다The present invention improves the structure of the reinforcing rod and the adhesive zone in the conventional spiral tube and improves the structure of the reinforcing rod and when the concentrated external pressure is applied to the adhesive zone to solve the problem and to increase the durability against light and external pressure Have a problem
