Abstract
The invention discloses a composite flat-wall polyethylene steel-plastic drain pipe. A pipe body is formed by winding polyethylene hollow plastic sections, two adjacent polyethylene hollow plastic sections are connected by using hot melt glue through hot melt welding, and steel-plastic belt sections are wound around the inner wall of the pipe body. Because the pipe body of the composite flat-wall polyethylene steel-plastic drain pipe is formed by winding the polyethylene hollow plastic sections and the steel-plastic belt sections are arranged inside the pipe body for supporting, the consumption of plastics is greatly reduced. Especially for a large-caliber pipe body, the total weight of steel and plastics is lower than the weight of a common winding pipe, so that the raw materials can be effectively saved. The steel-plastic belt sections can be used for supporting the pipe body of the drain pipe, so that the ring rigidity of the drain pipe is greatly increased, product performance is improved, and the service life of the drain pipe is prolonged.
Description
Technical field
The present invention relates to a kind of gutter, particularly a kind of bore polyethylene hollow winding clad steel is moulded and is strengthened the planomural gutter.
Background technology
In the urban sewerage and drainage pipe, traditional concrete duct is substituted by present plastic drain-pipe, and existing plastic drain-pipe mainly contains double-wall corrugated pipe, hollow binary wall twisting and pipe, three kinds of forms of two flat walls steel-plastics composite pipe.The ring stiffness of double-wall corrugated pipe pipe is lower, the equipment price costliness, and manufacturing cost is higher, and the bellows-shaped on the surface of this gutter determined this tubing generally ground excavation can only be constructed when installing, and construction is comparatively complicated.Heavy caliber hollow binary wall twisting and pipe is the domestic a kind of pipe line made up of full plastics that begins to develop in 2000, and weight is big, and the material that needs is more, and along with the anxiety gradually of present resource, this heavy caliber hollow both arms wind pipe is eliminated gradually because of cost of production is higher.The two flat walls steel-plastics composite pipe adopts galvanized steel strip, and steel band separates with plastics, owing to steel band acid and alkali-resistance not, corrosion easily, and gutter is mainly used in urban sewerage and drainage, blow-off line, and pipe mainly adopts outer the connection, so long-time use steel band is easy to corrosion, thereby influences the use of gutter.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the technical problem to be solved in the present invention provides a kind ofly can save resource, has high strength again, the gutter of corrosion resistance characteristic.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of compound planomural polyethylene steel-plastic gutter, its body is Wrapping formed by polyethylene hollow plastic section bar, adopts PUR to connect by sweat soldering between the adjacent polyethylene hollow plastic section bar, is wound with plastic-steel banding pattern material on the inboard wall of tube body.
Preferably, described body top layer also scribbles one deck high-density polyethylene plastics coating.
Preferably, described plastic-steel banding pattern material surface scribbles one deck PE plastics.
Preferably, two corners of described plastic-steel banding pattern material and the welding of described polyethylene hollow plastic section bar are one.
Preferably, described polyethylene hollow plastic section bar end face corner is made as fillet.
Preferably, described polyethylene hollow plastic section bar end face corner is provided with one and strengthens the angle.
Technique scheme has following beneficial effect: the body of this compound planomural polyethylene steel-plastic gutter is Wrapping formed by polyethylene hollow plastic section bar, its inside is provided with plastic-steel banding pattern material and supports, make the consumption of plastics significantly reduce, particularly for the heavy caliber body, the gross weight of steel and plastics is also lower than the weight of common wind pipe, can effectively save material, plastic-steel banding pattern material can support the body of gutter, the ring stiffness of gutter is improved greatly, improve properties of product, prolonged the application life of gutter.
Above-mentioned explanation only is the general introduction of technical solution of the present invention, for can clearer understanding technological means of the present invention, and can be implemented according to the content of manual, below with preferred embodiment of the present invention and conjunction with figs. describe in detail as after.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Description of drawings

The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described in detail.
As shown in Figure 1, the body of this compound planomural polyethylene steel-plastic gutter is Wrapping formed by polyethylene hollow plastic section bar 1, adopt PUR 2 to be connected to form the helical corrugation tube shape between the adjacent polyethylene hollow plastic section bar 1 by sweat soldering, be wound with plastic-steel banding pattern material 3 in the ripple helicla flute of inboard wall of tube body, plastic-steel banding pattern material surface scribbles one deck PE plastics.Also scribble one deck high-density polyethylene plastics coating 4 on the body top layer, high-density polyethylene plastics coating 4 makes it to form smooth smooth appearance (as shown in Figure 5) by the roller rolling.
As shown in Figure 2, polyethylene hollow plastic section bar 1 is provided with bottom surface 12 and end face 11, when making mould, considers the polymer viscosity that high-density polyethylene material is higher, and end face corner 13 places can be made as fillet.Again as shown in Figure 3, the rotation angle position of bottom surface 12 and end face 11 also increases by one and strengthens angle 14, the easier moulding of this section bar that can make like this.
As shown in Figure 4, plastic-steel banding pattern material 3 is provided with top 31 and crimping 32, and the corner 33 of top 31 and crimping 32 junctions is designed to circular shape, and when the pipe of design different size, crimping 32 can suitably be increased.Two corners 33 and polyethylene hollow plastic section bar 1 weldable of plastic-steel banding pattern material 3 are one.
This compound planomural polyethylene steel-plastic gutter adopts a kind of brand-new form of structure, and plastic-steel banding pattern material 3 is coated with last layer PE plastics earlier uniformly before entering the winding die head, can protect plastic-steel banding pattern material 3 like this, and plastic-steel banding pattern material 3 just can not corroded like this.The corner of plastic-steel banding pattern material 3 and polyethylene hollow plastic section bar 1 are bonded as one fully, can improve the ring stiffness of body so greatly; Body top layer hot melt spiral is coated with last layer high-density polyethylene plastics 4, and the tension that can improve pipe rises intensity, stops to occur the bourdon tube phenomenon, is convenient to gutter and adopts more advanced form of construction work.
This compound planomural polyethylene steel-plastic gutter since plastics closely be connected with steel band, so the ring stiffness of body is higher, lighter with similar other products pipe quality of comparing under identical ring stiffness situation; Smooth smooth appearance can be selected hot melt band, multiple connected modes such as heat shrinking sleeve and socket joint for use.
More than a kind of compound planomural polyethylene steel-plastic gutter that the embodiment of the invention provided is described in detail; for one of ordinary skill in the art; thought according to the embodiment of the invention; part in specific embodiments and applications all can change; in sum; this description should not be construed as limitation of the present invention, and all any changes of making according to design philosophy of the present invention are all within protection scope of the present invention.
