Description

PE double-flat-wall steel-plastic composite water drainage pipe

Technical field

The utility model relates to tubing art, refers in particular to a kind of PE double-flat-wall steel-plastic composite water drainage pipe.

Background technique

The pipeline being conventionally used to various draining that municipal administration, industry, agricultural and traffic engineering construction etc. use and drainage is generally concrete duct, its Heavy Weight, it is very inconvenient to install, have plastic winding tube at present, it is lightweight, easy for installation, in the last few years along with the expanded demand in market and the needs of development of company, winding tube production line is in continuous increase, and the output of entwining tube also can progressively increase.

But it is not good enough that current entwining tube also exists strength deficiency, corrosion resistance and weatherability, therefore, be necessary to improve the entwining tube of object.

Summary of the invention

In view of this, the utility model is for the disappearance of prior art existence, and its main purpose is to provide a kind of PE double-flat-wall steel-plastic composite water drainage pipe, and it effectively can solve the not good enough problem of existing entwining tube strength deficiency, corrosion resistance and weatherability.

For achieving the above object, the utility model adopts following technological scheme:

A kind of PE double-flat-wall steel-plastic composite water drainage pipe, include body, etch resistant layer and weathering layer, this body is PE material, in this body, there is looping pit, be provided with steel band in this looping pit, this etch resistant layer is covered on the internal face of body, and this weathering layer is covered on the outer surface of body.

Preferably, described steel band includes a horizontal part, two rakes and two hook portions, this two rake is connected with the two ends of horizontal part are one-body molded respectively, and the two ends of this two hook portions are connected with the tail end of two rakes is one-body molded respectively, the two side snap fit of two hook portions and looping pit.

The utility model compared with prior art has obvious advantage and beneficial effect, specifically, as shown from the above technical solution.

This quality of product is excellent, intensity is high, moderate, easy for installation, facilitate the construction of no-dig technique pipeline, be country advocate to mould for product made from steel, municipal blowdown, expressway, sports ground storm-water drainage engineering and draining, flood control, field irrigation etc. can be widely used in, also can be used as other and bury cable sleeve, purposes widely.Product transport, handling facility, easy construction, simple and easy, not being afraid of collision, is the optimal update products such as cement pipe, cast iron tube, Glass Steel Tube.

For more clearly setting forth structure characteristic of the present utility model and effect, below in conjunction with accompanying drawing and specific embodiment, the utility model is described in detail.

Accompanying drawing explanation

Accompanying drawing identifier declaration.

10, body 11, looping pit

20, etch resistant layer 30, weathering layer

40, steel band 41, horizontal part

42, rake 43, hook portion

Embodiment

Please refer to shown in Fig. 1, that show the concrete structure of the preferred embodiment of the utility model, include body 10, etch resistant layer 20 and weathering layer 30.

This body 10 is PE material, has looping pit 11 in this body 10, is provided with steel band 40 in this looping pit 11, and this etch resistant layer 20 is covered on the internal face of body 10, and this weathering layer 30 is covered on the outer surface of body 10.

In the present embodiment, described steel band 40 includes horizontal part 41, two rake 42 and a two hook portions 43, this two rake 42 is connected with the two ends of horizontal part 41 are one-body molded respectively, the two ends of this two hook portions 43 are connected with the tail end of two rakes 42 is one-body molded respectively, the two side snap fit of two hook portions 43 and looping pit 11.

This product has following main feature.

One, bore is large, wide in variety.Its internal diameter is 300mm-1600mm, can for different engineering.

Two, lightweight.Be significantly less than the weight of concrete pipe, be convenient to transport.

Three, good mechanical property, intensity are high.Resistance to punching press, anti-outer load performance excellence, toughness of material is good.Be out of shape recoverability after External Force Acting strong, product resistance to settling is excellent, has good adaptability to any ground.

Four, cold-resistant, ageing-resistant performance is excellent.Tubing is generally black, can bear the sun deposited with in work progress and directly shine, can not be caused Seepage at low temperature environment by bursting by freezing and expansion.

Five, there is good chemical resistance.Do not corroded by sewage, waste water and chemicals, do not corroded by erosion in soil.

Six, material friction coefficient is little, excellent in abrasion resistance.Than steel pipe, concrete abrasion-resistant, Living Water waste residue transport force is strong.

Seven, connect reliably, easy construction.Employing burning-on method connects, rapid and convenient.Pipe laying only needs excavator, without the need to main equipment.Tubing can first connect outward at ditch, then places in groove, can reduce must engineering time and expense, engineering construction, management, maintenance cost are low.
