The present invention relates to a reinforced spiral pipe of synthetic resin spiral pipes widely used as a drainage pipe and a sewer pipe and a manufacturing apparatus thereof. Conventionally, various products and manufacturing apparatuses have been provided for external pressure reinforcement of a synthetic resin spiral tube composed of a hollow portion or a support portion and a recessed portion of a spiral winding. 9)] Designed to provide an improved product reinforcement and easy manufacturing process, the conventional design is to extrude the reinforcing rod extruded tube in a separate auxiliary die for external pressure reinforcement and durability reinforcement to form an extrusion hole in the die lip with an adhesive roller When the spiral tube is manufactured, it is designed to simultaneously extrude the extruded tube and integrally to form a V-shaped reinforcement with an adhesive roller at the same time.It is designed to provide real users by reinforcing not only external pressure strength but also durability and breakage strength. The detailed description is as follows. As shown in Figs. 1 and 3, the reinforcing bar formed integrally on the upper surface 12 'or the corner of the hollow part 12 of the spiral pipe 1 for the external pressure reinforcement of the reinforcing spiral pipe is used as the groove part reference. Spiral winding by integrating the V-shaped reinforcement table 5 into the joining table 4 so that the hollow spheres (a) and (a ') are formed at the same time as being integrated with the fusion table 13 on the upper side of the hollow part 12 on the other side. Reinforced both side walls of the hollow part 12 with the V-shaped reinforcement table 5, among which the wall surface is reinforced with the quadruple wall surface, so that the external pressure reinforcement and breakage strength reinforcement and the production cost are also inexpensive. The description is as follows.

[Example 1]

As shown in FIG. 2, the fusion zone 3 is formed in the spiral bone between the hollow portions 12 in the longitudinal direction, and the semi-circular protrusions 2 are formed intermittently in the spiral length direction. It is designed to support both sides of the wall, and to provide external pressure reinforcement and durability.

[Example 2]

As shown in Fig. 4 (a) and (b), the grooves between the hollow portions 12 constitute a V-shaped reinforcing bar 5 with a cross section between the wall surface and the V-shaped (tilt) reinforcing bar 5. Designed to support the reinforcing rib (6) to each other to improve the external pressure strength and to provide a breakage strength reinforcement, in this case by forming a support portion (12 ") in which the hollow section is omitted instead of the hollow portion 12 It is designed to integrate the V-shaped inclined reinforcing bar (5) by the joining table (4) to the reinforcing ribs (6) formed on both side walls.

[Example 3]

As shown in FIG. 5, it is designed to expand the use of the reinforcement spiral pipe (1), and is used in the fusion joint (4) for use as a culvert drainage pipe suitable for an area where a swamp or ground of a construction site passes through groundwater. It is designed to intermittently configure the drilling tool (20).

[Example 4]

As shown in FIG. 6, the upper portion of the upper portion of the hollow wall 12 for bending reinforcement of the hollow portion 12 is configured as a product for external pressure reinforcement. Even if the hollow sphere (a) (a ') is formed, the product is provided with reinforced external pressure and durability.

[Example 5]

As shown in FIG. 7, even if the entire area of the recess is integrated with the fusion splicing base 3 ', the product provides breakage strength and durability.

[Example 6]

As shown in FIG. 8, even when the bar-shaped protrusions 2 are intermittently formed in the recessed portions of the fusion zone 3 'and the V-shaped reinforcement 5, the external pressure reinforcement and durability of the present invention It is a devised design provided.

As the manufacturing apparatus of the present invention, as shown in FIGS. 9, 10, and 12, the extrusion bracket of the die lip 9 in the manufacturing apparatus of the spiral tube 1 composed of the die 8 and the molding machine 19 assembled in the extruder. A tube 17 "is formed integrally with the corner portion of the spiral tube 7" by forming a detention 17 'at the upper side or the corner portion 18 of the hollow part extruded portion of (7). An adhesive roller having an adhesive table 10 formed immediately after the spiral roller is fixed to the upper surface of the hollow part 12 by the auxiliary roller 15 when the spiral winding is made by the rotation of the forming roller 16 by extrusion. 11) is a device that manufactures a reinforcing spiral tube that is integrated into the joint (4) formation and the cross-section is composed of the V-shaped reinforcement (5) when the compression is rotated while pressing the die (9) in the die lip (9 ') Formed on the middle part of the upper surface 18 of the compression mold 7 and when using the main surface auxiliary roller 15, the adhesive roller ( 11) to compensate for the shortcomings and to use the adhesive roller (11) formed with the adhesive groove 14 to form the semi-circular protrusion (2) intermittently in the groove portion of the spiral tube (1).
