Abstract
The utility model relates to an underground drainage pipeline and provides a steel strip compounded polyethylene wound pipe with the advantages of reasonable structure, excellent sealing property, tight and firm connection of faying surfaces, high annular stiffness and high strength. The steel strip compounded polyethylene wound pipe is formed by continuously winding a hollow polyethylene section bar and performing hot melt glue welding connection, wherein a steel strip is arranged in the pipe wall of the hollow polyethylene section bar and extends along the length direction of the hollow polyethylene section bar.
Description
Technical field
The utility model relates to subsoil drain, particularly a kind of steel band composite polyethylene entwining tube.
Background technique
In municipal drainage,, therefore substituted by existing plastic drain-pipe gradually because the traditional cement pipeline exists the shortcoming of corrosion-resistant, life-span weak point, joint easy to leak.Existing plastic drain-pipe mainly contains double-wall corrugated pipe, hollow binary wall twisting and pipe and three kinds of forms of two flat walls steel-plastic composite pipe, wherein, in various drainage pipes, uses hollow binary wall twisting and pipe the most generally; Advantages such as this pipeline has corrosion-resistant, good toughness, tempers toughness with gentleness, and is easy for installation; But existing hollow binary wall twisting and pipe is formed by connecting the hollow binary wall twisting and pipe that pure plastic material is entwined all-plastic square hollow material through continuous helical winding, thermofussion welding; Ring stiffness and intensity are low; If run into collision extruding such as hard stone or metal, the surface is prone to cause pit or perforation, influences its using effect.
In addition, existing hollow binary wall twisting and pipe is after twining welding, and the faying surface welding is insecure, and the phenomenon that frequent appearance is leaked or ruptured from the weld joint is not only used to people and made troubles, and increased maintenance cost.
Summary of the invention
To the problems referred to above, the utility model proposes a kind of rational in infrastructure, good seal performance, faying surface connects close and firm, has epipodium stiffness and high-intensity steel band composite polyethylene entwining tube.
For solving this technical problem; The utility model is taked following scheme: a kind of steel band composite polyethylene entwining tube; The polyethylene hollow material twine continuously, PUR weldering is formed by connecting; Be provided with steel band in the tube wall of said polyethylene hollow material, said steel band extends along polyethylene hollow material length direction.
Further improvedly be: said steel band is the flute profile steel band, and the opening of said flute profile steel band is in the polyethylene wound pipe pipe.
Further improvedly be: be evenly distributed with through hole on the said flute profile steel band, said through-hole diameter is the 2-5 millimeter.
Further improvedly be: a side of said polyethylene hollow material is provided with the buckle slot of depression, and opposite side is provided with the buckle of the convexity that is complementary with the buckle slot that caves in, and is connected with being clasped through said buckle slot between the said polyethylene hollow material.
Through adopting the aforementioned techniques scheme; The beneficial effect of the utility model is: the utility model steel band composite polyethylene entwining tube; Polyethylene hollow material being provided with steel band in the tube wall twines continuously, the PUR weldering is formed by connecting, and its intensity, rigidity are 3 times of common entwining tube, and because the barrier action of steel band; Make its impact resistance, be difficult for perforation; Said steel band is the flute profile steel band, and the opening of said flute profile steel band has increased the ability of polyethylene hollow material outer wall opposing pressure outside and impulsive contact force, the working life of having improved polyethylene wound pipe in the polyethylene wound pipe pipe; Be evenly distributed with through hole on the said flute profile steel band, said through-hole diameter is the 2-5 millimeter, through the through hole on the flute profile steel band, make the polyethylene hollow material after extruding and moulding with flute profile steel band strong bonded together; One side of said polyethylene hollow material is provided with the buckle slot of depression, and opposite side is provided with the buckle of the convexity that is complementary with the buckle slot that caves in, and twines continuously; When PUR connects, is connected with being clasped through said buckle slot between the said polyethylene hollow material, make that polyethylene hollow material continuous helical twines, when PUR welds the faying surface connection tightr; Increased the area of contact of faying surface, firm welding has solved existing technology entwining tube faying surface weld joint and has been prone to the phenomenon of leaking or rupturing; It is simple in structure; Reasonable in design, easy to use, reduced maintenance cost.

Embodiment
Combine accompanying drawing and specific embodiment that the utility model is further specified at present.
With reference to figure 1 and Fig. 2, present embodiment discloses a kind of steel band composite polyethylene entwining tube, polyethylene hollow material 1 twine continuously, PUR weldering is formed by connecting; Be provided with steel band 2 in the tube wall of said polyethylene hollow material, said steel band extends along polyethylene hollow material length direction, the polyethylene hollow material that is provided with steel band in the tube wall twine continuously, the PUR weldering is formed by connecting; Its intensity, rigidity are 3 times of common entwining tube, and because the barrier action of steel band makes its impact resistance; Be difficult for perforation; Said steel band 2 is the flute profile steel band, is U type shape, and the opening of said flute profile steel band is in the polyethylene wound pipe pipe; Opening has increased the ability of polyethylene hollow material outer wall opposing pressure outside and impulsive contact force, the working life of having improved polyethylene wound pipe in pipe; Be evenly distributed with the through hole (not shown) on the said flute profile steel band, said through-hole diameter is 3 millimeters, through the through hole on the flute profile steel band, make the polyethylene hollow material after extruding and moulding with flute profile steel band strong bonded together.
One side of said polyethylene hollow material 1 is provided with the buckle slot 11 of depression, and opposite side is provided with the buckle 12 of the convexity that is complementary with the buckle slot that caves in, and twines continuously; When PUR connects, is connected with being clasped through said buckle slot between the said polyethylene hollow material 1, make that polyethylene hollow material continuous helical twines, when PUR welds the faying surface connection tightr; Increased the area of contact of faying surface, firm welding has solved existing technology entwining tube faying surface weld joint and has been prone to the phenomenon of leaking or rupturing; It is simple in structure; Reasonable in design, easy to use, reduced maintenance cost.
The above record is merely the embodiment who utilizes this origination techniques content, anyly is familiar with modification, the variation that this creation of this art utilization is done, and all belongs to the claim of this creation opinion, and is not limited to embodiment announcement person.
