Description
Technical field
The utility model relates to pipe technology field, is specially the winding reinforcing pipe that one has polypropylene (PP) stiffening rib, is especially applicable to a kind of novel enhanced pipe being applied in municipal rain, sewage water discharge aspect.
Background technique
Polypropylene (PP) stiffening rib winding reinforcing pipe material is the buried rain, the dirty waste pipe that have all generally used both at home and abroad already, has the advantages such as service life is long, steady quality is reliable, electro-fusion socket is easy to connect, good leak tightness.
Along with the increase of urban population number, in the designing requirement medium caliber of buried pipeline in continuous increasing, simultaneously along with the increasing of bore, also need the larger buried degree of depth, the ring stiffness index that these conditions all require tubing to possess more to increase, prevents from occurring the phenomenons such as conquassation in using process.
As the important indicator ring stiffness of buried pipeline, produce raw-material Young's modulus to tubing and tubing axial rotation inertia is directly proportional, be inversely proportional to 3 powers of pipe diameter.In order to meet high ring rigidity requirement, idea reduces raw material usage as far as possible again simultaneously, only has the Young's modulus by improving raw materials and implements improvement in certain approach with increasing tube wall rotary inertia when doses as far as possible.Because polypropylene Young's modulus is far longer than high density polyethylene (HDPE), but the anti-aging deficiency of polypropylene, and so allow it be combined with high density polyethylene (HDPE), designing specific structural walls, is more satisfactory approach.Market, current home and abroad have employed the structure-wall pipe material of metal or other materials and high density polyethylene (HDPE) composite winding, but the design of its composite structure wall is unreasonable, have there is very serious resistance to compression weak spot in structure and cause tubing entirety be not a high strength, corrosion-resistant, overall structure, also there are steel band and plastics compound not to combine and effect is not play to the raising of ring stiffness, and, plastics are not a kind of materials with metal, easy separation, product poor corrosion resistance.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of winding reinforcing pipe with polypropylene stiffening rib, to solve the problem in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of winding reinforcing pipe with polypropylene stiffening rib, comprise body, described body utilizes winding unit spiral winding to form, on the overlap joint linear slit of described adjacent winding unit, to have cage walls to carry out airtight in welding, described cage walls inner wall smooth is smooth, inside is fitted with polypropylene stiffening ring, the external diameter of described cage walls is 1.2 times of described polypropylene stiffening ring external diameter, described polypropylene stiffening ring adopts single-wall corrugated pipe, the contact internal walls of the ripply outer wall of its tool and described cage walls, the inside of described polypropylene stiffening ring is then provided with polypropylene stiffening rib, described polypropylene stiffening rib is in the diametrical position of described polypropylene stiffening ring, and it is vertical with described winding unit.
In the utility model, as a kind of technological scheme of improvement, described winding unit adopts polyethylene flat rubber belting, and the overlap edge of described polyethylene flat rubber belting edge is inclined plane shape.
In the utility model, as a kind of technological scheme of improvement, the both sides of described polypropylene stiffening rib are provided with the identical polypropylene thickening layer of thickness, and polypropylene thickening layer can combine together with described polypropylene stiffening rib.
In the utility model, as a kind of technological scheme of improvement, polypropylene stiffening rib is vertical with described winding unit, and therefore after winding unit spiral winding, polypropylene stiffening rib can be in radial Hand of spiral, improve the ring stiffness of entwining tube, PP materials'use amount can be saved simultaneously.
In the utility model, the diameter of polypropylene stiffening ring and wall thickness, the thickness of winding unit, the thickness of polypropylene stiffening rib and height and pipe material inner wall thickness can determine rational numerical value according to different rings rigidity grade.
Owing to have employed above technological scheme, the utility model has following beneficial effect:
Polypropylene stiffening ring combines with polypropylene stiffening rib, improves the ring stiffness of polypropylene (pp) stiffening rib winding reinforcing pipe, under meeting the prerequisite of winding structure pipe intensity, saves PP material, saves the energy adding man-hour; Stiffening ring is inserted in stiffening ring from polyethylene cage walls opening, and the inwall of stiffening ring is withstood in the end of polypropylene stiffening ring, and polypropylene stiffening rib improves the intensity of polypropylene stiffening ring, forms the entwining tube of B type after winding unit overlap joint.
In sum, the utility model is rational in infrastructure, polypropylene (PP) is made to be in the self-enclosed structure of a polyvinyl plastics, both improve the ring stiffness of tubing, and possessed again all advantages of plastic tube, and ensure that the stability of pipe structure, under meeting the prerequisite of winding structure pipe intensity, save raw material, save the energy adding man-hour, improve company interest.
