본 발명을 도면에 의거 상세히 설명하면Referring to the present invention in detail based on the drawings

도2 및 도3에 도시된 바와 같이 보강부(2)와 접합부(11)으로 나선권회되어 일체화된 종래의 나선관 에서는 지중매설 하여 장시간 사용하여야 하므로 지역에따라 하중이 집중적으로 가해지는 경우에는 보강부(2)의 사이사이에 형성된 접합대(11) 부위가 원주방향으로 파손되는 취약점이 노출되는바 본 발명에서는 구조가 간단하면서 고강도의 제품 제공하므로서 이의 해결을 위하고 또 본 발명의 제품에서 취약점으로 사료되는 외토압의 보강을 위하여 안출된 제품으로서 보강부(2)의 중간벽(2A)의 양측 부위에서 받침대(8)을 돌출시켜 외측방향으로 경사시켜서 보강부(2)의 상측벽(2B)와 같이 외측덮개(4)로 외접시켜 주어서 구성된 발명으로서 지중 매몰시켜 장기간 사용하면 매몰된 주위의 토양으로부터 외토압이 외측덮개(4)로부터 가해지므로 보강부(2)의 중간벽(2A)에서 돌출되어 외측방향으로 형성되어 외측덮개(4)로 일체된 받침대(8)의 구조적인 보강으로 외토압이 보강되며 이때 보강부(2)에 도3에 도시된 바와같이 중공구(6)을 형성하여 주어도 본 발명의 제품이 제공되는 발명이다As shown in Figs. 2 and 3, in the conventional spiral tube spirally wound and integrated into the reinforcing part 2 and the joint part 11, it must be used for a long time by underground embedding. The vulnerabilities in which the joint 11 formed between the parts 2 are damaged in the circumferential direction are exposed. In the present invention, the structure is simple and provides a high-strength product for solving the problem and in the product of the present invention. As a product designed for reinforcement of external soil pressure, the upper wall 2B of the reinforcing part 2 is inclined outward by protruding the pedestal 8 from both sides of the middle wall 2A of the reinforcing part 2. As an invention configured by externally enclosing the outer cover (4), the earthquake is buried in the soil for a long time, so that the external soil pressure is applied from the outer cover (4). The external pressure is reinforced by the structural reinforcement of the pedestal 8 which protrudes from the partition wall 2A and is formed in the outward direction and is integrated with the outer cover 4, wherein the hollow sphere is shown in FIG. (6) is an invention provided with the product of the present invention even if formed

이때 본 발명에서 외측덮개(4)의 실시예로서는 도4 및 도5에 도시된 바와같이 보강부(2)의 상측벽(2B)이 노출되도록 상측벽(2B)에 융착되면서 요홈덮개(3)로 받침대(8)의 단부에 일체로 고정시켜 주면 받침대(8)와 요홈덮개(3)의 접합부위가 견고히 일체화되어서 외토압이 가해질 경우 중간벽(2A)의 굽힘 응력이 보강이 되어서 경량화되는 고강도 구조 보강용 나선관의 제공이 되며 실시예를 설명하면 다음과 같다At this time, as an embodiment of the outer cover 4 in the present invention as shown in Figures 4 and 5 to the groove cover 3 while being fused to the upper wall (2B) to expose the upper wall (2B) of the reinforcing portion (2) If the fixing part is integrally fixed to the end of the pedestal 8, the joint portion of the pedestal 8 and the recess cover 3 is firmly integrated, and when the external pressure is applied, the bending stress of the middle wall 2A is reinforced to reduce the weight, thereby increasing the weight. The reinforcing spiral pipe is provided and describes an embodiment as follows.

도6에 도시된 바와 같이 보강부(2)의 굽힘응력을 분산시켜서 구조적으로 균일하게 외압이 적용하도록 요구되는바 이의 대책으로서 요홈덮개의 중간부에 보강대(5)가 형성된 단면이형 보강대(5')를 외측덮개(4)로 외접하여 일체시켜 형성하고 보강부(2)의 하측벽(2C)의 두께를 보강하여 중간벽(2A)의 요홈 덮개(3)가 일체로 융착된 두께와 같이 보강시켜 주면 구조적으로 외토압 보강용 배수관이 제공된다As shown in Fig. 6, the cross section in which the reinforcing table 5 is formed in the middle of the groove cover is required to disperse the bending stress of the reinforcing part 2 and to apply the external pressure structurally uniformly. The reinforcing member 5 'is formed by externally covering the outer cover 4 and integrally formed, and the groove cover 3 of the intermediate wall 2A is integrally fused by reinforcing the thickness of the lower wall 2C of the reinforcing part 2. If it is reinforced with the same thickness, the drain pipe for external pressure reinforcement is structurally provided.

도7에 도시된 바와 같이 도6에서 도시된형 보강대(5')에서 보강대(5)를 2개 이상의 다수개로 형성시켜 주면서 외측덮개(4)로 외접하여 일체화되도록 부착하고 하측벽(2C)의 두께를 보강하여 형성된 제품이다As shown in FIG. 7, as shown in FIG. It is a product formed by forming the reinforcing bar 5 in the form of a plurality of reinforcing bar 5 'and attaching it so as to be externally integrated with the outer cover 4 and reinforcing the thickness of the lower wall 2C.

상기 설명한 바와같이 본 발명은 배수관의 단면구조를 개선하여서 외토압에 대하여 강도가 증대되는 효과가 있는 것이다As described above, the present invention has the effect of increasing the strength against external pressure by improving the cross-sectional structure of the drain pipe.

특히, 본 발명은 합성수지제로된 배수관에 있어 강도가 약한 재질적 특성의 단면구조를 개선하므로서 고강도의 제품을 제공할수 있는 유익한 발명인 것이다In particular, the present invention is an advantageous invention that can provide a high-strength product by improving the cross-sectional structure of the material properties of weak strength in the synthetic resin drain pipe.
