Abstract
The utility model discloses a composite flat wall polyethylene steel plastic drain pipe, wherein a pipe body is formed by winding hollow polyethylene plastic sections, the adjacent hollow polyethylene plastic sections are connected through hot melt glue by hot melt welding, and the inner wall of the pipe body is winded with plastic steel belt sections. The pipe body of the composite flat wall polyethylene steel plastic drain pipe is formed by winding the hollow polyethylene plastic sections, the interior of the pipe body is supported by the plastic steel belt sections, so that the quantity of the plastic can be greatly reduced, especially, for the pipe body with large caliber, the total weight of the steel and the plastic are lower that the weight of the common winding pipe, the raw material can be effectively saved, the plastic steel belt sections can support the pipe body of the drain pipe, so that the circular rigidity of the drain pipe can be greatly improved, the performance of the product can be improved, and the service life of the drain pipe can be prolonged.
Description
Technical field
The utility model relates to a kind of waste pipe, and particularly a kind of bore polyethylene hollow winding Composite Steel is moulded and strengthened the planomural waste pipe.
Background technique
In the municipal 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-plastic composite pipe.The ring stiffness of double-wall corrugated pipe pipe is lower, the equipment price costliness, and manufacture cost is higher, and the bellows-shaped on the surface of this waste pipe 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 entwining tube is eliminated gradually because of cost of production is higher.The two flat walls steel-plastic composite pipe adopts Galvanized Steel Strip, and steel band separates with plastics, owing to steel band acid resistant alkali not, corrosion easily, and waste pipe is mainly used in municipal 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 waste pipe.
The model utility content
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 waste pipe of corrosion resistance characteristic.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of compound planomural polyethylene steel-plastic waste pipe, its body is Wrapping formed by polyethylene hollow plastic section bar, adopts hot melt adhesive 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 waste pipe 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 entwining tube, can effectively save material, plastic-steel banding pattern material can support the body of waste pipe, the ring stiffness of waste pipe is improved greatly, improve product performance, prolonged the working life of waste pipe.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.

Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, the body of this compound planomural polyethylene steel-plastic waste pipe is Wrapping formed by polyethylene hollow plastic section bar 1, adopt hot melt adhesive 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 spiral chute 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 joints 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 waste pipe adopts a kind of brand-new structural type, 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 waste pipe and adopts more advanced form of construction work.
This compound planomural polyethylene steel-plastic waste pipe 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 Placements such as heat-contraction sleeve and socket joint for use.
More than a kind of compound planomural polyethylene steel-plastic waste pipe that the utility model embodiment is provided be described in detail; for one of ordinary skill in the art; thought according to the utility model embodiment; part in specific embodiments and applications all can change; in sum; this description should not be construed as restriction of the present utility model, and all any changes of being made according to the utility model design philosophy are all within protection domain of the present utility model.
