Description

Synthetic resin reinforced spiral tubes {omitted}

The present invention relates to a synthetic resin reinforced spiral tube (hereinafter referred to as a reinforced spiral tube) widely used for drainage pipes.

In general, when reinforcing spiral pipe is buried under ground and used for a long time as drainage pipe, reinforcing spiral pipe is divided into hollow sphere and I beam structure in terms of product structure. In the construction area, there is a problem that the area where the hollow sphere is formed is broken in the spiral tube formed by the spiral winding due to uneven load or ground subsidence.

Thus, in order to solve the above problems, a product was provided in which the hollow spheres integrated with the spiral windings on both side walls were filled with a hard resin zone, a rigid foam, or a reinforced resin tube.

However, the reinforcement spiral pipe provided above has good external pressure in the small size of the drainage pipe of Φ300m / m or less when the structure of the spiral pipe is in the longitudinal direction, but in the medium and large sizes of Φ600m / m or more, Due to the relatively weak external pressure reinforcement, more high-strength products are required to expand the demand for reinforced spiral pipes and provide robustness.

The present invention is provided to reinforce the above-mentioned problems, and is integrated with the hollow spheres and both sidewalls or joints for averaging the high-strength rigidity of the I-beam structure portion integrated with the hollow spheres and both sidewalls in the conventional spiral tube. Reinforced helix provided with the same thickness of the existing spiral pipe by overlapping each other in upper and lower sides by dividing the spiral pipe into two and three layers with the same thickness as the existing thickness of the same spiral pipe standard It is devised to compensate for the weakness of the hollow sphere part that is filled by reinforcing the hollow sphere of each layer with hard foam and hard resin band in the pipe.
