Abstract
The invention belongs to the field of pipe structures, and discloses a continuously-wound enhancement structural wall pipe and a production method thereof. A hollow reinforcing rib of the continuously-wound enhancement structural wall pipe has external ripples formed by fixedly sticking at least two special-shaped single-wall corrugated pipes. Due to the fact that the special-shaped single-wall corrugated pipes can be bent freely with no internal stress and can be in a proper shape selectively, the height and bending of the hollow reinforcing rib can have the wide selection range in the winding forming process, and the structural wall height and inertia moment of the pipe are increased; accordingly, the ring rigidity of the pipe is enhanced economically; meanwhile, due to the hollow reinforcing rib formed by sticking the special-shaped single-wall corrugated pipes, the structure is firmer and more stable.
Description
Technical field
The present invention relates to the production method that a kind of continuous winding strengthens structure-wall pipe material and this tubing.
Background technique
There is the polyethylene spirally enwound structure-wall tubular product of hollow structure, the little advantage of bore large (maximum caliber reaches 4 meters in the market), equipment investment can be produced because it has, be widely used in municipal drainage, blowdown pipeline network construction.
At present, the manufacture method of polyethylene spirally enwound structure-wall tubular product has two kinds usually.
The first manufacturing process of aforementioned tubes.First extrude the banded section bar of the polyethylene with various hollow structure by the first extruder, after vacuum water is cold formed, is spirally wound on side by side regularly continuously and is equipped with on the circular forming cylinder of many active rotation roller bearings.Again by the second extruder constantly to the polyethylene melten gel clamp-oning molten state between the banded section bar of spiral winding side by side, roll through pinch roller, the adjacent regions of banded section bar is by polyethylene melt adhesive together.Because the hollow structure of banded section bar is different, form the polyethylene spirally enwound structure-wall tubular product with various hollow structure type.As polyethylene spirally enwound structure-wall A type pipe, internal-rib helical bellows, winding bellows etc.But there is following defect in this technique:
(1), banded section bar forms tube wall by melt adhesive again after water-cooled, owing to being cold and hot bonding, can have influence on the quality of cemented side seam due to the temperature control deviation of banded section bar; Simultaneously due to melten gel and the cooling of banded section bar non-concurrent, cooling meat also causes inner-walls of duct level and smooth not.
(2), banded section bar is bending again after water-cooled is wound around, and it is height-limited that bending internal stress determines such pipe structure, and shaping rear tube wall moment of inertia is little, is unfavorable for the ring stiffness improving tubing economically.
The another kind of manufacturing process of polyethylene spirally enwound structure-wall tubular product.First by the banded melten gel of the first extruder polyethylene extrusion melting, banded melten gel suitably cools, be in semi-molten soft state, this banded melten gel by continuously regularly wound side by side on forming cylinder, because banded melten gel is in semi-molten state, mutual overlap joint is namely bonding afterwards to be merged, and forms the cylindric tubing body of real wall.Use polypropylene single wall ripple pipe simultaneously, through the coated polyethylene of the second extruder compound die, because polypropylene softening temperature is higher than polyethylene, collapse so polypropylene single-wall corrugated pipe can not be heated.The polypropylene single-wall corrugated pipe of coated molten polyethylene collapses in spiral winding mode and is pressed on the fusion seam position that on pipeline body, melten gel band overlaps mutually, the polyethylene of molten coated on bellows and the melten gel band of two-layer overlap joint merge mutually and bond together, and form the polyethylene spirally enwound structure-wall Type B pipe with circular hollow stiffening rib.This kind of technique ensure that the quality of entwining tube cemented side seam, also because inwall melten gel band chilling temperature is close, makes inwall level and smooth compared with the pipe material inner wall of the first explained hereafter.The shortcoming of this kind of technique existence is, be that the round structure that skeleton is formed can not form optimum support by polypropylene single-wall corrugated pipe due to stiffening rib, single-wall corrugated pipe is owing to being subject to the high temperature of coated hot melt adhesive conduction simultaneously, cross section can become oval, the width of hollow reinforced rib is caused to be greater than height, also reduce the structure height of tubing, after being shaped, tube wall moment of inertia is little, is unfavorable for the ring stiffness improving tubing economically.
Therefore be necessary to provide a kind of winding structure wall pipe and the production method with hollow reinforced rib, to overcome the various shortcomings of above-mentioned technique and structure.
