The present invention improves the blood spiral pipe for water and sewage pipes used for underground water supply and drainage pipes in underground construction works such as construction and roads, and integrates the outer surface with the recess and junction points intermittently in the spiral winding direction on the inner side. Spiral pipe, which is a product provided by assembling and fixing the fastening device of the present invention to the junction where the recess is formed, the construction and road construction that allows the space between the inner and outer surfaces to penetrate in the longitudinal and circumferential directions Of fastener double wall pipe for water and sewage pipe

In general, PE spiral pipes have been used as drainage pipes because the inner surface is smooth and hollow spheres are formed in the pitch reinforcement of the outer surface, so that they are spiral wound, but for diversification of their use or for thermal insulation or external pressure reinforcement. Reinforced by filling the inner space of the hollow sphere with cement mortar.

This is because the spiral pipe made of synthetic resin covers the inner and outer surfaces of the concrete drainage pipe formed by curing the mortar of cement, so the reinforcement for durability and impact is very high. However, cement mortar is applied to the inner space of the spiral pipe by laying underground. It is difficult to fill cement mortar because the adhesive force of the joint part made of synthetic resin is insufficient in the filling process.

In the process of filling cement mortar into the inner space at the construction site, grooves are formed by the viscosity and weight of the mortar's fluidity, and the contact point integrated on the inner surface is peeled off due to insufficient adhesive force. It is a reality that raises a problem

Therefore, as a self-governing solution for the product, a reinforcing device provided by fixing the fastening bolts to the ramp and the adhesive point was provided, but this improved the workability for the field construction, but it was pointed out that the trouble of assembling at each junction point was a problem. Therefore, it takes time and manpower accordingly, so there is an unreasonable point to provide economic feasibility.

The present invention in the above pointed PE spiral tube through the inner space between the inner surface and the outer surface in the longitudinal direction and the circumferential direction through the cement mortar by filling the inlet formed on one side of the outer surface to reinforce the external pressure and strength strength When using underground buried cement mortar to provide a product that is configured to provide robustness by forming a coupling rod externally so as to be reinforced with high-strength adhesive strength to the contact point integral to the inner surface while the groove is formed to effectively fill the work will be

The present invention solves the above problems, and in particular, when the cement mortar is filled in the inner space between the inner surface and the outer surface formed by the spiral winding of the PE spiral pipe, the adhesive force is formed to penetrate in the longitudinal direction and the circumferential direction. Fastening to reinforce the assembly sphere by bending the weak outer surface to form grooves and integrally joining rods with iron cores on the outer surface in the spiral winding direction so that the coupling force is reinforced at the joint points integrated with the inner surface. The stand is fixed externally, providing a through section formed in the gap between the recess in the inner space, and integrating the inner and outer surfaces into one another to induce diversification of use while stably using it in the construction site. Invention for providing a product for providing a release composite product such as thermal insulation foam and cement mortar. If it described in detail based on drawings as follows.

Generally, a predetermined space A is formed between the inner side surface 4 and the outer side surface 9 and penetrates into the space between the grooves in the longitudinal direction and the circumferential direction, and is formed at one side of the outer side surface 9. Filling the cement mortar (7) into the inner space (A) through the inlet (5) (5 '), the cement mortar (7) flowing stably in the release process in the process of evenly filling the inner space (A) In the blood spiral tube in which the flow is made of synthetic resin, normal work is impossible due to the peeling phenomenon of the junction 3.
Therefore, in order to provide a stable product therewith, as shown in FIGS. 1 to 5, the inner and outer surfaces 4 and 9 are overlapped with each other, while maintaining a constant interval in the spiral wound blood tube 1.
