Abstract
The utility model discloses a jacketed wall large-size plastic pipeline. The utility model is formed by equal diameter continuous constant pitch wrapping of rectangle hollow beams 1. Two rows of V-shaped recesses 3 are arranged on the two sides of the rectangle hollow beams1. A plastic adhesive tape adhesion layer 2 is arranged in the thread pitch slits between adjacent rectangle hollow beams1. Inverted V convex rings 4, which are detained with the V-shaped recesses, are arranged on the two side of the plastic adhesive tape adhesion layer 2. The jacketed wall large-size plastic pipeline has advantages not only including light in weight, easy in transportation, construction and erection, no leak-out, and easy in connection, but good anti-fracture ability, low in production cost, simple in facilities and low in investment and so on. The utility model is widely applicable to the main pipelines of field irrigation diversion works and municipal building drainages.
Description
Technical field
The utility model relates to a kind of water drainage plastics tubing, and especially a kind of dual-layer wall heavy caliber water drainage plastics pipe is applicable to field irrigation diversion works and urban engineering project drain header road.
Background technique
Along with the expansion of field irrigation diversion works and urban construction water supply and sewage work to the tubing demand, green heavy caliber pipe has become the focus in tubing market in recent years, this type of heavy caliber pipe, still use materials used for cement pipes at present mostly, be with the deficiency of materials used for cement pipes: making needs a large amount of reinforced concrete, thick heaviness, difficulty of construction is big, the transportation difficulty, seepage is difficult for repairing easily; The someone had developed the large-caliber double-wall waved plastic pipe in recent years, to replace cement pipe, the advantage of this waved plastic pipe is: low weight, transportation installation easily, connect reliable, easy to leak not, but also have deficiency, significant disadvantages is: producing this corrugated plastic pipe material needs large-scale manufacturing mechanism, complex process, invest hugely, improved cost of production, therefore also influenced and promoted the use of, simultaneously, this waved plastic pipe is because of there being certain distance between the ripple, fracture has reduced bearing capacity easily.
Summary of the invention
The purpose of this utility model is to provide a kind of can not only overcome the shortcoming that the heavy caliber cement pipe is had, and low, the easy processing of cost of production, equipment investment is little, intensity is high dual-layer wall heavy caliber water drainage plastics pipe.
For reaching above purpose, the technological scheme that the utility model adopted is: this dual-layer wall heavy caliber water drainage plastics pipe, be entwined continuously by same diameter uniform pitch by the rectangle hollow pipe, at first producing section is the strip tubing of rectangle, on Wrapping formed machine, twine then, the bi-side of rectangle hollow pipe are provided with two row " V " connected in stars, inner face and outside are the plane, after being wound in the spiral pipe, establish the plastic glue strip bonding layer in the pitch slit of adjacent rectangle hollow tubular, establish " V " shape bulge loop that interlocks with " V " connected in star in plastic glue strip bonding layer both sides, the close and firm more so that plastic glue strip bonding layer and rectangle hollow pipe bond, guarantee the intensity of heavy-caliber plastic pipe, to strengthen the bonding firm degree of rectangle hollow pipe, easy-rupturing is not difficult for producing seepage, this plastic glue strip bonding layer can be in rectangle hollow pipe winding process thermosol pour and form the smooth outer surface of pipe.The utility model is also implemented by following measure: the winding inner diameter of described rectangle hollow pipe is 160-2000mm, double-deck wall thickness 20mm-140mm, the section of rectangle hollow pipe can be a square, also can be rectangular, the winding pitch 20-150mm of rectangle hollow pipe.
The beneficial effects of the utility model are: compare with the heavy caliber bellows of present use, not only have advantages such as in light weight, transportation and construction and installation easily, non-leakage, easy connection, but also having not advantage such as easy-rupturing, cost of production is low, equipment is simple, little investment, its ring stiffness can reach S
2More than the level, reach as high as S
4Level (is 16KV/m
2), internal pressure-resistant can reach 1Mpa, and tensile strength is greater than 2300, and resistance to frost is good, but in subzero 40 ℃ of proper functioning.
