Description

Reinforced COnstructure of Sprial Pipe}

The present invention relates to a PE spiral pipe used for drainage by laying in the ground, and to provide more economical pressure reinforcement and firmness than when it is used in underground laying by reinforcing the structure of a spirally wound reinforced hollow sphere.

In general, in the case of civil engineering and building construction, the spiral pipe used for drainage by laying in the ground is manufactured to a certain length for transportation or construction, and is used by laying underground at the construction site. Same as

PE spiral pipe, which has been widely used in the related art, has a reinforcing hollow tool 11 spirally wound on the outer surface of a pipe, and the external pressure reinforcement is formed, but the bending stress of both side wall 13 of the reinforcing hollow tool 11 is a spiral pipe. In this case, the bending pressure appears when the external pressure strength reaches a certain limit, and at the same time, the cross section of PE spiral pipe is deformed into an elliptical bar. In this design, a reinforcing hollow tool of spiral pipe of the same standard is used to solve this problem. ) Is reduced to about half, but the auxiliary hollow sphere 18 extruded from a separate die is integrated with the upper side 13 of the reinforcing hollow tool 11 and the lower side 22 of the secondary hollow tool 12. When fusion is fused but integrally fused to both sides 12 of the reinforcing hollow tool 11 by the coupling rib 17, both side wall 12 is reinforced by the coupling rib 17 at the same time lowering about half the height of the existing standard Bending strength beams are welded and reinforced by wall (19) It is to provide products that become steel.

The present invention was devised to solve the above problems, while structurally reinforcing both side surfaces 12 and the upper side 13 to reinforce the bending stress in the reinforcement hollow tool portion of the PE spiral pipe and inclined to both sides It is a product that reinforces the support for external earth pressure reinforcement by reinforcing the rigidity by forming the support.
