Abstract
The reinforced polyethylene pipe has double layer wall and into the hollow part between the two layers, stuffing material of waste plastic is filled to raise strength and specific weight. The reinforced pipe is used to replace cast iron pipe and favorable to solving environmental pollution. The reinforced pipe features the space for fluid to flow and with circular cross section; the outer wall, the inner wall and the ridges as connecting bridge in between forming quadrangular hollow parts; and the reinforcing stuffing filled into the hollow parts and of reused resin, which contains inorganic matter and is extruded and filled in the shape with flat cross section.
Description
Technical field
The present invention relates to polyethylene pipe.In particular, it relates to and improves the polyethylene double-wall pipe be generally used for upper and lower water course etc., allows it keep the more fully polyethylene pipe of epistasis.
Background technique
Usually, be used for the polyethylene pipe of purposes such as sewer, utilize polyethylene resin to be squeezed into the inner hollow portion that forms square shape after, this is fused into spirality form, and is molded into body.
By the polyethylene pipe (1) of above-mentioned operation moulding,, shown in Figure 3 as Fig. 1; The circular fluid flow space (2) that formation can allow fluid move, the hollow portion (7) that the outside double wall of being made up of exterior wall (3) and interior wall (4) (5) and cross structure-ridge (6) form four jiaos of type shapes.
Above-mentioned general polyethylene pipe is compared with the polyethylene pipe of single wall because of the double wall of hollow space, and characteristics such as epistasis is superior, corrosion resistance is strong are arranged, and is suitable for sewer or draining and sewage conduct.
But above-mentioned polyethylene pipe is compared with plain cast iron pipe or concrete reinforced pipe, and shortcomings such as weak strength, light specific gravity, buoyancy difference are arranged.Above-mentioned polyethylene pipe can expose or is stranded a little less than the epistasis damaged easily after burying underground because of buoyancy.So can't be used in the middle of the actual life.In order to address these problems, some company is the hollow space between double wall also, acquires resin material and adds full hollow space.But this also because adding full hollow space can't scatter one's forces, problems such as epistasis weakens occur.
Summary of the invention
The present invention is in order to address the above problem, and the hollow portion between double wall is acquired the filler of the useless north material of utilization moulding that can the abundant intensity of reinforcement, improves intensity and proportion with this, replaces cast iron tube, helps to solve environmental problem simultaneously.

Embodiment
Fig. 4 adopts the part of the polyethylene pipe of the technology of the present invention to analyse oblique drawing, Fig. 5 is the polyethylene pipe C-C line that adopts along Fig. 4, the sectional view that extracts, Fig. 6 is the polyethylene pipe that adopts from Fig. 5, extract the sectional view of D part, Fig. 7 is in the polyethylene pipe that adopts of Fig. 5, extracts the sectional view of the D part of other illustrations, among the present invention, being described as follows of relevant polyethylene pipe through reinforcement.
Common polyethylene pipe (30) needs to form the section that can allow fluid move and is circular fluid circulation space (31).The outside of above-mentioned fluid circulation space (31), the square shape hollow portion (40) that the double wall of being made up of exterior wall (32) and interior wall (33) (35) and bridge-ridge (36) form.Characteristic of the present invention is, in order to improve the intensity and the proportion of above-mentioned hollow portion (40), filling therein reinforcing material (41).
Above-mentioned reinforcing material (41) utilizes the arbitrarily discarded useless north material in rural area to carry out moulding, and needing does not have to remove under the state of the inorganic substances that contained in the useless north material, and it is Shu shape that regenerating resin is squeezed into section, and it is filled in the hollow space (40).The loading that above-mentioned reinforcing material (41) is accepted in order to disperse, middle body can also form loading dispersion hole (50).Above-mentioned polyethylene pipe of the present invention (30) in the hollow portion (40) of common polyethylene pipe (30), so filling improves intensity and proportion because of containing the heavier reinforcing material of inorganic substances proportion (41) with this, substitutes the cast iron tube that generally uses.
The most important thing is that polyethylene pipe of the present invention (30), the reinforcing material (41) of filling hollow space (40) are to use the arbitrarily discarded useless north material in rural area to carry out moulding, to preventing the pollution of the environment, also can make suitable contribution.
The hollow space of invention as above in order to form between the double wall of strengthening polyethylene pipe, the filler by the moulding of the useless north material of filling utilization can substitute cast iron tube, also helps to solve environmental problem.
Claims (3)
1. polyethylene pipe through reinforcement is characterized in that comprising:
Form the rounded fluid circulation space (31) of section that fluid can move;
