본 발명은 지중 매설하여 널리 사용하는 상하수관용으로 사용되는 고강도 나선관(이하에서는 고강도 나선관이라 칭한다)에 관한 것이다.The present invention relates to a high strength spiral tube (hereinafter referred to as a high strength spiral tube) used for water and sewage pipes which are widely used underground.

일반적으로 고강도 나선관을 지중 매설시켜 급,배수관용 등으로 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 지반 침하 등으로 나선권회로 구성된 나선관에서 중공구가 형성된 부위가 취약한 구조로 파손되는 문제점이 있어서 고강도 나선관의 사용범위가 넓지 못하는 문제점이 있었다.In general, when high-strength spiral pipes are buried underground and used for a long time for supply and drainage pipes, high-strength spiral pipes are classified into hollow spheres and I-beam structures due to the structure of the product. In the construction area that does not correctly carry out the problem of the hollow tube formed in the spiral winding structure due to the unbalanced load or ground subsidence is damaged due to the fragile structure of the hollow sphere, there was a problem that the use range of the high-strength spiral pipe is not wide.

그래서, 상기와 같은 문제점을 보완하기 위하여 양측벽면으로 서로 나선권회로 일체화시켜 준 중공구에 경질수지대 또는 경질 발포체 또는 보강 수지관 등을 충만 시켜준 제품이 제공되었다.Thus, in order to compensate for the above problems, a product was provided in which a hollow resin sphere, which is integrated with a spiral winding on both side walls, is 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

Figure 112006504373002-pat00076
300m/m 이하인 소형 규격에서는 외토압 등이 양호하나
Figure 112006504373002-pat00077
800m/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 is a drainage pipe when the structure of the spiral pipe in the longitudinal direction
Figure 112006504373002-pat00076
In the small size of 300m / m or less, the external pressure is good.
Figure 112006504373002-pat00077
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 견고성을 위하여, 중공구와 양측벽면이나 접합대로 일체화되는 나선관을 2～3등분시켜 2층 및 3층 구조로 중첩시켜 중공구 부위의 취약점을 보완하기 위한 발명이다.The present invention is to provide a reinforcement of the problems presented above, in order to strengthen the strength of the high-strength of the portion of the I-beam structure that is integrated into the hollow sphere and the side wall in the conventional spiral tube, the spiral tube is integrated with the hollow sphere and both side wall or junction It is an invention to compensate for the weakness of the hollow sphere part by dividing it into 3 layers and overlapping it into 2 layer and 3 layer structure.

본 발명은 상기 설명된 구조 보강 나선관을 제공하기 위한 발명으로서 나선관의 중공구에 단면이 ━형 지지대 또는

The spiral reinforcing bar is formed on the upper, lower and both side walls of the hollow sphere, and has been provided with a spiral tube manufactured by integrating both side walls with a spiral winding.

따라서 본 발명을 상기 설명된 도면에 의하여 상세히 설명한다.Accordingly, the present invention will be described in detail by the above-described drawings.

본 발명에서와 같이 중공구간에 단면이

Figure 112006504373002-pat00057
형 보강대(19)가 형성된 경우에는 중공구의 형상이 2층 구조로 되어 있으므로, 배수로관으로 지중 매설하여 장기간 사용하는 경우에는 외토압의 보강을 높혀 주기에 구조상 한계가 있다.
따라서, 중,소형 규격 위주로 사용될 수 밖에 없으므로, 이에 대한 외토압 보강을 위한 해결을 위한 실시예로서 제품을 제공하기 위한 발명으로서, 도4에 도시된 바와 같이 상기 설명된 중공구간에 단면이

Figure 112006504373002-pat00057
Since the hollow sphere has a two-layered structure when the type reinforcing rod 19 is formed, there is a structural limitation in increasing the external earth pressure reinforcement in the case of using it underground for a long time by laying it in the drainage pipe.
Therefore, the invention is to provide a product as an embodiment for solving the external pressure reinforcement for this, because it can only be used mainly in the small and medium size, the cross section in the hollow section described above as shown in FIG.
Figure 112006504373002-pat00058
In the hollow section formed of both side walls (12) and the upper and lower sides (15, 16) instead of the type reinforcement (19)

The cross section of the main part of the reinforced product formed by integrally forming the type reinforcement
Figure 112006504373002-pat00089
Since the hollow sphere is formed as a three-layer structure as a type reinforcing structure, the external pressure reinforcement is increased to provide a medium and large sized product.

The invention provides a structural spiral reinforcement pipe 25 that is reinforced with a two-layer structure that solves a weakness such as breakage occurring in a hollow section of the hollow spheres 11 and 11 'and increases external pressure reinforcement.

여기서 사용되는 융착 보강층(가)에서는 본 발명의 보강 나선관(25)을 제조하는 경우 양측 표면이 평활한 상태로 형성되므로, 융착 표면에서 제조 공정 도중에 기포 등이 혼입하여 매끄럽게 융착되지 못하는 단점이 있는바, 이에 대한 해결을 위하여 상,하측면으로 돌출부가 원주방향으로 교호상으로 돌출되는 단면이

As an invention provided to reinforce external pressure reinforcement and robustness in the structurally reinforced product of the hollow sphere 11 reinforced by the shape reinforcing rod 19, the thickness T of the same specification is divided into two to three equal parts. The invention consists of forming a fusion reinforcement layer that overlaps the hollow spheres on the upper and lower sides to form a fusion reinforcement, and as a reinforcement structure, bends both side wall surfaces of each hollow sphere formed in a two to three-layer structure, By providing an integrated product, it is a useful invention that can be used stably for a long time in the construction site because it reinforces the vulnerability of the hollow ball, which is highlighted as a weak point when underground settlement or uneven load of the buried area is applied.
