Description

Reinforcement spiral tube

The present invention relates to a reinforced spiral pipe widely used for sewer pipes and drainage pipes buried underground.

In general, the spiral tube is integrated with the spiral winding circuit while maintaining a constant distance as the fusion splicing, the inner surface is smooth and the outer surface is a reality using the product consisting of the groove portion and the hollow portion protruded at a constant interval in the longitudinal direction.

Therefore, in the case of long-term use of the spiral pipe body in which the spiral winding circuit and the fusion zone are repeatedly integrated into the spiral winding circuit in the ground, the hollow section provides a double structure to the upper side and the inner side at the hollow portion maintaining a constant width. If the sewage flowing inside the spiral pipe flows quickly in the sand and soil, the inner wall of the spiral pipe made of synthetic resin is worn out and there is a high risk of breakage when used for a long time.

In addition, since the fusion zone is fused to the spiral winding in the manufacturing process of the spiral pipe and formed on the inner side, as described above, foreign materials such as sand and soil flowing into the sewage are subjected to wear and burial of the fusion zone and external pressure is applied. It is a reality that a problem arises in the quality of the spiral tube which should be used for a long time.

In order to reinforce the above problem, the spiral tube circumscribed by the outer wall surface at the upper side of the hollow part provides the effect of forming the reinforcing bar at the fusion site and strengthening it, but this is a reality that provides only the same effect as the double wall surface of the hollow part.

In addition, the spiral tube which is integrally formed on the inner side and smoothly along the convex portion protruding to the inner side in the corrugated structure in which the protruding portion is formed alternately in the longitudinal direction is internally indented to provide a separate inner side provided as in the case of long-term use. The product is also a slight reality to provide the wear protection and external pressure reinforcement effect.

In particular, the spiral tube formed of the hollow portion and the welded portion is a situation where the reinforcement structure against external pressure and inner wear has a problem in practical use as described above, and the use range is very narrow.

The present invention solves the above-described problems, while in the conventional spiral tube formed integrally with the spiral winding circuit, the hollow portion formed in the spiral tube in the longitudinal direction at regular intervals formed by one rotation of the spiral winding circuit, that is, one pitch, is formed. It is devised to provide abrasion resistance and external pressure reinforcement at the inner side while inscribed a plurality of reinforcement to the inner side while being small.

The present invention is as shown in Figs. 1 and 2 in the spiral tube 1 which is formed while the hollow portion 2 protrudes and the fusion zone 14 is maintained at a constant distance in the longitudinal direction as described above. On the inner side of the hollow part 2 and the inner side of the fusion base 14, a plurality of reinforcements (3) (3 ') (3 ") (4) (4), each subdivided into a plurality of pieces to reinforce external pressure and breakage strength ') (4 ") is formed integrally formed in one pitch section to reinforce by subdividing the interval in the longitudinal direction of the hollow portion (2) and fusion zone (14) and reinforcement (3) (4) As it is reinforced with overlapping structure, it shows durability against abrasion such as sand and soil mixed with sewage flowing inside the spiral pipe, thus providing products for stable use in the long term.

In general, the spiral pipe (1) used in the underground buried in the hollow part (2) when the structure of the spiral pipe (1) is used to analyze the structure of the upper side and the inner side and the fusion zone 14 is a manufacturing process In the spiral tube manufacturing machine, the fusion zone 14 integrally overlaps the fusion portions protruding from the lower portion of the hollow portion 2 formed at regular intervals while rotating in a spiral winding, making the structure more fragile than the hollow portion 2 portion. In order to reinforce its weakness, as shown in Fig. 3, only the hollow part is provided with a plurality of reinforcing holes (3) (3 ') (3 ") which are subdivided into the longitudinal width of the hollow part (2) on the inner side. It is devised to provide a product configured by placing the reinforcing holes 4 and 4 'on both side portions of the side wall portions of the hollow portion 2, respectively.

At this time, it is necessary to reinforce the weaknesses in the recessed portion of the fusion zone 14 to be formed, so for the reinforcement thereof, as shown in FIGS. 4 and 5, the cross section is located on the upper side of the hollow part 2. The upper surface and the cross section of the concave arc-shaped or hollow portion 2 form the outer wall surface 6, 6 'in a straight line, and the reinforcing sphere 4' is formed in the middle portion of the fusion zone 14, as described above. It is a product that provides a reinforcement structure of the fusion zone 14 part.

In the spiral tube of the present invention, in general, in the structure of the hollow part 2, the structure of both wall surfaces 2 'is buried in the ground and external soil pressure is applied when it is used for a long time. The circumferential cross section of the fusion zone 14 is bent in an elliptical direction and is curved in an elliptical shape to provide a structure for long-term use as a reinforcement thereof. As shown in FIG. 6, the upper side of the hollow part 2 is provided. When the support 7 is formed at the intermediate position of the recessed portion of the fusion splicer 14 by fusion welding on both side walls 2 'to the middle upper portion of the hollow portion 2, the external pressure is applied. Even if the support strength of both side wall surface (2 ') is reinforced, the product is provided that the spiral tube 1 of the present invention is firmly reinforced.

At this time, instead of the support 7 described in FIG. 6, a concave portion is formed in a hemispherical reinforcement 8 formed by alternately successively repeating convex portions and concave portions in the longitudinal direction spirally wound into the recessed portions of the fusion splicing 14. Providing a product configured integrally with the concave portion in the fusion zone 14 is also devised to provide the reinforcement product described above.

In addition, the spiral tube used in the underground buried in the hollow portion (2) between the inner surface and the outer wall surface 6 is composed of a spiral winding, so the thickness gap is very wide, so when buried underground and used for a long time If the circumferential cross section is deformed, the thickness of the outer circumferential surface is high, so that the tensile force acts on the outer wall surface 6 to reinforce it. It is required to configure the structure of the holder 9 to form a portion, but is fixed with a reinforcing bar (9 ') between the convex portions, as shown in Figures 8 and 9 of the hemispherical reinforcement described in Figure 7 The invention provides a spiral tube that is fused and strengthened integrally by a fixing bar 9 fixed to a convex part formed while forming a predetermined gap on the upper side of the hollow part 2 by an integrated reinforcing bar 9 '.Also provide excellent reinforcement product pressure or the like.

The present invention is a product in which a plurality of reinforcing parts are subdivided into the inner surface by reinforcing integrally in the pitch formed in a predetermined width in a spiral tube formed by a generally repeated hollow portion and a fusion zone in the longitudinal direction. In addition to reinforcing the fragility that is damaged by the concentrated load of the fusion zone, as well as the support and hemispherical reinforcement, sufficient strength to be applied to the construction site is maintained, it is a useful product excellent in workability, economical efficiency, external pressure reinforcement.
