Abstract

PROBLEM TO BE SOLVED: To reduce the weight so as to facilitate handling by sequentially winding a spiral cushioning cloth tape and a double-layer reinforcement stainless steel tape round the outer periphery of a conduit made of a specified resin, and the stacking a cushioning layer formed of foaming material and a specified resin layer thereon. SOLUTION: A resin-made conduit l provided in the center part is formed by extrusion molding of high density polyethylene, and a cushioning cloth tape 2 is spirally wound round the outer periphery and fixed by an adhesive. Subsequently, a first reinforcement stainless steel tape 3 is wound in the reverse spiral direction round the outer periphery and fixed by an adhesive, and further a second reinforcement stainless steel tape 4 is spirally wound round the outer periphery and similarly fixed by an adhesive. On the outside of the spirally wound second reinforcement stainless steel tape 4, a cushioning layer 5 is formed by a foaming material of a synthetic resin formed of foaming propolyprene or foaming polyethylene or the like, and a corrosion preventive straight chain low-density polyethylene layer 6 is formed thereon by an extrusion molding method. Thus, a transport pipe which is more light-weighted and inexpensive than the steel pipe can be manufactured.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transportation pipe for sewage, sewage, human waste, and the like.

[0002]

2. Description of the Related Art Conventionally, sewage, sewage,
Transport pipes for human waste are well known.

[0003]

Since the above-mentioned known products are made of steel pipes or cast steel pipes, they are heavy and difficult to handle.
Price was also expensive.

[0004]

An object of the present invention is to provide a transportation pipe for sewage, sewage, human waste, etc. which is easy to handle and inexpensive.

SUMMARY OF THE INVENTION Accordingly, the present invention relates to a high-density polyethylene resin conduit 1 formed at the center and formed by extrusion, and spirally wound around the resin conduit 1 and adhered. Buffer cloth tape 2 fixed with an adhesive, and a considerably thick first reinforcing stainless tape 3 wound around the outer periphery of the buffer cloth tape 2 in a spiral and fixed with an adhesive
A second reinforcing stainless tape 4 wound around the outer periphery of the first reinforcing stainless tape 3 in a spiral and fixed with an adhesive; Or a buffer layer 5 made of a synthetic resin foam material formed of expanded polystyrene or expanded polyurethane, or the like;
This is a transport pipe for sewage, sewage, human waste, etc., composed of an anticorrosive linear low-density polyethylene layer 6 formed on the upper surface of the buffer layer 5 by extrusion.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings.
Reference numeral 1 denotes a resin conduit provided at the center of a transport pipe for sewage, sewage, human waste, etc., which is formed by extrusion molding of high-density polyethylene.
Is spirally wound and fixed with an adhesive.
Then, the first reinforcing stainless tape 3 is wound in the opposite spiral shape and similarly fixed with an adhesive, and the second reinforcing stainless tape 4 is wound in the opposite spiral shape on the outer periphery as shown in FIG. Fix with adhesive.

The outside of the spirally wound second reinforcing stainless tape 4 is made of a foamed material of a synthetic resin formed of foamed polypropylene, foamed polyethylene, foamed polyester, foamed polystyrene, foamed polyurethane, or the like. The buffer layer 5 is formed, and the anticorrosion linear low-density polyethylene layer 6 is formed thereon by extrusion.

[0008]

The present invention relates to a transportation pipe for sewage, sewage, human waste, etc., in which a resin conduit 1 provided at the center by extrusion molding of high-density polyethylene is formed. The cloth tape 2 is spirally wound and fixed with an adhesive, and the first reinforcing stainless tape 3 is spirally wound around the outer periphery with an adhesive as shown in FIG. As shown in FIG. 6, the second reinforcing stainless tape 4 is wound in an opposite spiral shape and similarly fixed with an adhesive.

The outside of the spirally wound second reinforcing stainless steel tape 4 is formed of a foamed material of synthetic resin formed of expanded polypropylene, expanded polyethylene, expanded polyester, expanded polystyrene, expanded polyurethane, or the like. The buffer layer 5 is formed, and the anticorrosion linear low-density polyethylene layer 6 is formed thereon by extrusion.

[0010]

The present invention relates to a high-density polyethylene resin conduit 1 formed at the center by extrusion.
And a buffer cloth tape 2 spirally wound around the outer circumference of the resinous conduit 1 and fixed with an adhesive, and an equivalent spiral wound around the outer circumference of the buffer cloth tape 2 and fixed with an adhesive. A first reinforcing stainless tape 3, a second reinforcing stainless tape 4 wound around the outer periphery of the first reinforcing stainless tape 3 in a spiral and fixed with an adhesive; On the outside, a buffer layer 5 made of a foamed material of a synthetic resin formed of foamed polypropylene, foamed polyethylene, foamed polyester, foamed polystyrene, foamed polyurethane, or the like, and an anticorrosion linear formed on the upper surface of the buffer layer 5 by extrusion molding. Low density polyethylene layer 6
Since it is a transportation pipe for sewage, sewage, human waste, etc., made of high-density polyethylene resin pipe 1 formed by extrusion molding at the center, it is lighter and cheaper than steel pipe or cast pipe. Since the buffer cloth tape 2 is spirally wound around the outer periphery of the resin conduit 1 and fixed with an adhesive, the resin conduit 1 is protected, and the first reinforcing stainless steel tape 3 is disposed on the outer periphery of the buffer cloth tape 2. Is helically wound and fixed with an adhesive, and the second reinforced stainless tape 4 is wrapped twice around the outer periphery of the first reinforced stainless tape 3 in an opposite helical manner and fixed with an adhesive. Outside of the second reinforced stainless steel tape 4 is made of a foamed material of synthetic resin formed of foamed polypropylene, foamed polyethylene, foamed polyester, foamed polystyrene, foamed polyurethane, or the like. The 衝層 5 provided the anticorrosion formed by extrusion on the upper surface of the buffer layer 5 linear low density polyethylene layer 6
Provided, it is remarkably robust against abrasion, and is overwhelmingly resistant to cold compared to other materials, so it is suitable for use in cold climates. Occurrence is low. Further, since the anticorrosion linear low-density polyethylene layer 6 is provided on the upper surface of the buffer layer 5 by extrusion molding, the most difficult coating of the anticorrosion linear low-density polyethylene layer 6 can be performed most easily and easily. There is.
