Abstract

The utility model discloses a steel belt reinforced polyethylene helically-corrugated pipe and belongs to the field of pipe materials for municipal engineering. The defect that polyethylene helically-corrugated pipe metal materials in the prior art are large in consumption amount and high in manufacture cost is overcome. The key point of the technical scheme is that the steel belt reinforced polyethylene helically-corrugated pipe comprises a pipe body with a smooth inner wall, wherein an outer convex-rib-shaped hollow rib is helically wound on an outer wall of the pipe body, a steel belt with an opened trapezoidal cross section is arranged on an inner layer of the outer convex-rib-shaped hollow rib, and an inner polyethylene layer and an outer polyethylene layer are wrapped and covered on the inner side and the outer side of the steel belt. The steel belt reinforced polyethylene helically-corrugated pipe is mainly and widely applied to various drainage and sewerage systems for municipal engineering, the industry, the agriculture, traffic engineering construction and the like.

Description

Steel band reinforced polyethylene spiral ripple pipe

Technical field

The utility model belongs to a kind of tubing, specifically, relates in particular to the steel band reinforced polyethylene spiral ripple pipe that uses in a kind of municipal engineering.

Background technique

At present, metal enhancement mode polyethylene helical bellows is widely used in municipal engineering, the industry agricultural, various drainings and drainages such as traffic engineering construction, mostly adopt the hollow rib structure of helical arrangement, outer convex rib shape hollow rib internal layer is that cross section is the metallic material of circular curve, the metallic material outside covers the high-strength polyethylene material, steel band reinforced polyethylene spiral ripple pipe is in conjunction with the advantage of metal and plastics, can be with the high strength of steel, the corrosion resistance of high rigidity and plastics, wear-resistant, the pliability good characteristic organically combines, and brings into play the advantage of two aspects.

But, existing polyethylene helical bellows adopts the hollow rib structure of helical arrangement, in hollow rib, add the metallic material that section mostly is circular arc or tubulose, the consumption of polyethylene helical bellows metallic material that manufacturing has this kind hollow rib structure is bigger, and product weight is bigger, and manufacture cost is higher.

Summary of the invention

In order to overcome the above-mentioned defective that exists in the prior art, the utility model provides a kind of steel band reinforced polyethylene spiral ripple pipe.

The utility model steel band reinforced polyethylene spiral ripple pipe is realized by the following technical solutions: steel band reinforced polyethylene spiral ripple pipe, the pipeline body that comprises inner wall smooth, described pipeline body outer wall spiral is wound with outer convex rib shape hollow rib, it is the trapezoidal steel band of opening that outer convex rib shape hollow rib internal layer is provided with cross section, and outside parcel is coated with inside and outside polyethylene layer in the steel band.

Compared with prior art, the beneficial effect of the utility model steel band reinforced polyethylene spiral ripple pipe is: the utility model is in the requirement that guarantees the bellows working strength, reduced and produced the rolled steel dosage that this product consumes, alleviate the total quality of bellows, reduced the manufacture cost of bellows.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the I portion enlarged view of Fig. 1.

Among the figure: 1, pipeline body; 2, hollow rib; 3, outer polyethylene layer; 4, steel belt layer; 5, interior polyethylene layer.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

As shown in Figure 1 and Figure 2, a kind of steel band reinforced polyethylene spiral ripple pipe, the pipeline body 1 that comprises inner wall smooth, described pipeline body 1 outer wall spiral is wound with the hollow rib 2 of outer convex rib shape, outer convex rib shape hollow rib 2 internal layers comprise outer polyethylene layer 3, steel belt layer 4, interior polyethylene layer 5, the cross section of steel belt layer 4 is that opening is trapezoidal, this structure is under the prerequisite that guarantees the hollow rib support strength, reduced the consumption of steel, inboard and the outside that interior polyethylene layer 5, outer polyethylene layer 3 adopt the mode of adhere to wrap up sheathing tape layer 4.

Claims

1. steel band reinforced polyethylene spiral ripple pipe, comprise pipeline body (1), described pipeline body (1) outer wall spiral is wound with the hollow rib (2) of outer convex rib shape, it is characterized in that: described outer convex rib shape hollow rib (2) comprises outer polyethylene layer (3), steel belt layer (4), interior polyethylene layer (5), the cross section of described steel belt layer (4) is that opening is trapezoidal, inboard and the outside of interior polyethylene layer (5), outer polyethylene layer (3) parcel sheathing tape layer (4).
