Existing plastic tube mainly contains double-wall corrugated pipe, hollow binary wall twisting and pipe, Double-flat wall steel-plastic composite pipe three kinds of forms.Double-flat wall steel-plastic composite pipe adopts Galvanized Steel Strip, and steel band is separated with plastics, due to steel band not acid resistant alkali, easy corrosion, and tubing is mainly used in municipal drainage, blow-off line, and pipe mainly adopts outer connection, so long-time use steel band is easy to corrosion, thus affects the use of tubing.As publication number a kind of double-flat-wall steel-plastic tubing disclosed in the Chinese utility model patent of CN202597933U, it comprises the first flaggy, the second flaggy, is connected to the several piece vertical plate between the first flaggy and the second flaggy and embeds steel band; The outer strip of described first flaggy and the second flaggy is planomural; The two ends of each block vertical plate respectively with strip welding in the first flaggy and the second flaggy, between several piece vertical plate, fixed intervals are arranged; Embed steel band to be embedded between two pieces of adjacent vertical plates.Such scheme compression resistance and ring stiffness high, but because steel band is stuck between the first flaggy and the second flaggy, steel band easily and Cemented filling medium contact produce and corrode, such scheme does not arrange reinforced layer at the second flaggy in addition, cause the interior pressure of tubing not enough, the internal pressure easily brought because of tubing fed sheet of a media damages tubing.
Summary of the invention
Technical problem to be solved by this invention is to provide the polyethylene steel-plastic multipurpose composite pipe that a kind of ring stiffness is high, inner pressure resistant is strong, application is wide.
For solving the problems of the technologies described above, technological scheme of the present invention is as follows:
Polyethylene steel-plastic multipurpose composite pipe, comprise tube wall, described tube wall primarily of spiral winding and melting adhered multiple recombiner units form, described recombiner unit comprises outer strip, interior strip, at least 1 connecting band, enhancing steel rib, described outer strip and interior strip are planomural, connecting band is arranged at intervals between outer strip and interior strip, and described enhancing steel rib is then embedded in connecting band, is also embedded with steel wire along its length in interior strip inside.
Such scheme is preferred, and in order to strengthen the inner pressure resistant ability of tubing further, the grid of described steel wire is rhombus.
Such scheme is preferred, and in order to strengthen the ring stiffness of tubing further, the cross section of described recombiner unit is rectangle, and strengthens steel rib perpendicular to outer strip and interior strip.
Such scheme is preferred, and the width d of described enhancing steel rib is 8-100mm.
Such scheme is preferred, and the thickness of described enhancing steel rib is 0.8-3mm.
Such scheme is preferred; in order to strengthen the compressive strength of tubing further; with protection enhancing steel rib and steel wire are by the corrosion of sewage further, described recombiner unit is made up by steel plastic compount is one-body molded of outer strip, interior strip, connecting band, enhancing steel rib and steel wire.
Such scheme is preferred, and in order to improve the tensile strength of recombiner unit joint, extend the working life of tubing, the adhesion width D between adjacent recombiner unit is 40-300mm.
Such scheme is preferred, and in order to the tensile strength of recombiner unit joint improved further, adjacent recombiner unit is resin dedicated bonding by polyethylene.
Compared with prior art, the present invention has the following advantages:
1, enhancing steel rib, steel wire are embedded in connecting band, interior strip completely, avoid strengthening steel rib, steel wire contacts with water with air, enhancing steel rib is not corroded, and strengthen steel rib, steel wire can not be subjected to displacement, its good stability;
2, be embedded in steel wire in interior strip, the very big bearing capacity that improve pipe material inner wall, makes tubing can be applied to the special dimensions such as heavy caliber discharge pressure pipeline, petrochemical pipe.
3, strengthen steel rib all vertical with interior strip with outer strip, also enhance tubing road ring stiffness.
4, the bond area in addition between recombiner unit is large, and adhesive property is stablized, and also improves the tensile strength of abutting edge, extends the working life of tubing.
