Abstract
The utility model discloses a HDPE cavity wall plastic steel winding pipe, including body, waterproof layer and corrosion -resistant layer, this body forms tubular product by the strip after with adjacent edge reason overlap joint mode spiral winding in proper order and joint, and this strip is the polyethylene material, has the cavity cavity in the strip, and the inner wall subsides of this cavity are covered and are had the steel band, and this waterproof layer covers on the internal face of body, and this anti -corrosive layer covers in the waterproof layer on the surface. Through being provided with the steel band, utilize the steel band to make product structural strength effectively strengthen to steel band and strip shaping combine easily, and simple structure is firm, and the cooperation is provided with waterproof layer and anti -corrosive layer, the infiltration phenomenon appears in order to avoid the product, still further improve the corrosion resistance of product, thereby have prolonged the life of product greatly.
Description
Technical field
The utility model relates to tubing art, refers in particular to a kind of HDPE hollow wall plastic-steel winding.
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 helical bellows 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, helical bellows production line is in continuous increase, and the output of helical bellows also can progressively increase.
But, current helical bellows ubiquity strength deficiency, easily there is infiltration, the problem such as corrosion resistance is poor, working life is short, therefore, be necessary to improve the helical bellows of object.
Summary of the invention
In view of this, the utility model is for the disappearance of prior art existence, its main purpose is to provide a kind of HDPE hollow wall plastic-steel winding, and it effectively can solve existing helical bellows exists strength deficiency, easily occurs the problems such as infiltration, corrosion resistance is poor, working life is short.
For achieving the above object, the utility model adopts following technological scheme.
A kind of HDPE hollow wall plastic-steel winding, include body, watertightness barrier and anti-corrosion layer, this body forms tubing after also being engaged with neighboring edge successively overlapping mode spiral winding by band, this band is polyethylene material, in band, there is hollow cavity, the inwall of this hollow cavity is covered with steel band, and this watertightness barrier is covered on the internal face of body, and this etch resistant layer is covered on the surface of watertightness barrier.
Preferably, the inwall of described body is formed with helical groove.
Preferably, described steel band includes curved portions, two rakes and two hook portions, this belt body has a protuberance, this arc part is in protuberance, this two rake is connected with the both side edges of curved portions is one-body molded respectively, this curved portions and two rakes are all covered on the internal face of hollow cavity, and this two hook portions is connected with the lower ora terminalis of two rakes is one-body molded respectively, and two hook portions is all inserted in band.
The utility model compared with prior art has obvious advantage and beneficial effect, specifically, as shown from the above technical solution.
By being provided with steel band, utilize steel band that product structure intensity is effectively strengthened, and steel band is combined easily with band material forming, structure is simply firm, and be equipped with watertightness barrier and etch resistant layer, to avoid product to occur infiltration phenomenon, also improve the corrosion resistance of product further, thus substantially prolongs the working life of product.
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.

Embodiment
Please refer to shown in Fig. 1, that show the concrete structure of the preferred embodiment of the utility model, include body 10, watertightness barrier 20 and anti-corrosion layer 30.
This body 10 forms tubing after also being engaged with neighboring edge successively overlapping mode spiral winding by band 11, this band 11 is polyethylene material, there is in band 11 hollow cavity 101, the inwall of this hollow cavity 101 is covered with steel band 40, this watertightness barrier 20 is covered on the internal face of body 10, and this etch resistant layer 30 is covered on the surface of watertightness barrier 20.And the inwall of described body 10 is formed with helical groove 102.
Specifically, described steel band 40 includes curved portions 41, two rake 42 and two hook portions 43, this belt body 11 has a protuberance 111, this curved portions 41 is positioned at protuberance 111, this two rake 42 is connected with the both side edges of curved portions 41 is one-body molded respectively, this curved portions 41 and two rakes 42 are all covered on the internal face of hollow cavity 101, and this two hook portions 43 is connected with the lower ora terminalis of two rakes 42 is one-body molded respectively, and two hook portions 43 is all inserted in band 11.
Design focal point of the present utility model is: by being provided with steel band, utilize steel band that product structure intensity is effectively strengthened, and steel band is combined easily with band material forming, structure is simply firm, and be equipped with watertightness barrier and etch resistant layer, to avoid product to occur infiltration phenomenon, also improve the corrosion resistance of product further, thus substantially prolongs the working life of product.
Below know-why of the present utility model is described in conjunction with specific embodiments.These describe just in order to explain principle of the present utility model, and can not be interpreted as the restriction to the utility model protection domain by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other embodiment of the present utility model, and these modes all will fall within protection domain of the present utility model.
