In general, in order to reinforce earth pressure and lubrication of water, sewage pipes and conduits, spiral pipes of various structures have been provided by directly integrating both side walls of the reinforcement hollow part which is spiral wound and reinforced by both side walls. In other words, there was a weak point that the reinforcing hollow tools in the spiral wound were damaged in the circumferential cross section depending on the earth pressure.

In addition, to solve this problem, a product was provided in which a corrugated support and a support belt are integrally formed in a spiral recess formed by forming a predetermined interval between the reinforcing support parts and the spiral winding circuit. As the shaping support and the support belt are molded, the forming process of the reinforcing support is shrunk by cooling in the extrusion process of synthetic resin, which is the main raw material of the spiral tube. Durability reinforcement structure is necessary reality

In order to solve this problem, a product with a corrugated support inserted in the circumferentially helical groove exposed to the weakness in the joint between the reinforcing support parts in which the hollow sphere was omitted was provided in accordance with the application of the first invention. There is a need to provide a perfect reinforcing spiral tube that is more effective, durable and economically reconsidered.

Spiral pipes for water and sewage pipes and conduit pipes that are used for a long time by being buried in the ground are provided while maintaining a certain thickness for external pressure reinforcement, wherein the spirals formed by integrally fusion of both side wall surfaces of the reinforcing hollow part 22 in which the hollow holes 21 are formed. The pipe is buried in the ground and the hollow ball 21, which is a weak section in the spiral pipe, breaks in the spiral direction due to concentrated load or depression during long-term use.

In addition, the provision of the reinforcement support part 31 in which the hollow sphere 21 is not provided is excellent in external pressure and robustness, but the use of expensive equipment is very high due to the high occurrence rate of defects in the production process.

As a solution to the problems described above, the reinforcing structure such as the support belt and the outer wall surface integrally formed in the groove section between the reinforcing support portion 31 formed by the spiral winding while forming the reinforcing support portion and eliminating the structure of the conventional hollow sphere. Although the reinforcing spiral pipe was provided, the molding process of the reinforcing support part 31 is cooled and shrunk in the extrusion process of the synthetic resin, which is the main raw material of the spiral pipe. Durable reinforcing structure has been required

That is, the present invention distributes external shocks such as earth pressure and rotation pressure in the grooves of the joint table 33 between the thick reinforcing support members 31, which omit the hollow sphere 21 of the conventional reinforcing hollow portion 22. In order to meet the formation requirements of the structure that can be made by reinforcing the structure of the hollow section of the spiral wound hollow sphere 21 by integrally reinforcing and integrally fused to both side wall surface on the upper and lower portions of the reinforcing support part 31 As an invention for providing a spiral tube, a stress that breaks against the fragility of a hollow sphere portion consisting of a spiral tube in which a hollow sphere 21 of a conventional reinforcing hollow portion 22 is formed can be dispersed in the ground, It is to provide a product with good durability and durability by dispersing the impact or pressure applied even in the site.
