Abstract
The invention provides a method for producing steel-plastic multi-element composite pipes, which comprises the following steps of: modifying high-density polyethylene (HDPE) or polyvinyl chloride (PVC) plastics and manufacturing plastic plate strips; manufacturing hollow reinforcing ribs of which two side edges are recessed and overlapped; welding notches of the recessed bottoms of the reinforcing ribs by using continuous welding equipment; synchronously winding the welded reinforcing ribs with the plastic plate strips to form an inner wall of a pipe; coating and rolling on the wound pipe wall; coating a fiber mesh or winding a fiber strip and rolling on the rolled pipe wall; coating and rolling on a fiber layer to form an outer wall of the pipe; cutting the pipe which is finished in the seventh step at fixed length; sealing a port of each reinforcing rib at one end of the cut pipe, and injecting prepared cement slurry into each square reinforcing rib at the other end of the pipe by using grouting equipment; and finally, vertically erecting and fixing the pipe which is injected with the cement slurry, so that the cement slurry is solidified to form a finished pipe. The invention has the advantages that: the pipe can resist internal and external pressures and prevent cracking, an expansion on heating and contraction on cooling coefficient of the pipe is reduced, and the reinforcing ribs are prevented from rusting.
Description
Technical field:
The present invention relates to the tubing production technical field, refer in particular to the production method that a kind of steel is moulded polynary composite pipe.
Background technology
Is two great development trend to mould Dai Gang with the development pipeline transportation; Wherein, the high performance of plastic pipe, characteristics such as high-strength, lightweight, wear-resisting, anti-corrosion, inexpensive and heavy caliber have obtained using widely; Because this type of tubing rigidity and temperature tolerance are poor, can't be used for fields such as oil transportation and high pressure water delivery; And that the characteristics of metal tube are mechanical strengths is better, can not be out of shape, but its shortcoming is to get rusty easily.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, the production method that provides a kind of technology is simple, cost is low steel to mould polynary composite pipe.
For realizing above-mentioned purpose, technical scheme provided by the present invention is: a kind of steel is moulded the production method of polynary composite pipe, and described production method includes following steps:
First step: through modified device with HDPE or PVC plastics strengthen, toughening modifying, and be made into the plastics strip;
Second step: the hollow reinforcement that steel band is rolled into dual-side indent and mutual overlap joint through steel rolling equipment;
Third step: with of the notch welding of continuous welding equipment with recess in the reinforcement bottom;
The 4th step: reinforcement and plastics strip after will welding with the spiral Wiring apparatus are twined the formation inside pipe wall synchronously;
The 5th step: on Wrapping formed tube wall, cover glue, roll extrusion;
The 6th step: covered fiber net or winding fabric strip and roll extrusion on the tube wall of accomplishing the 5th step;
The 7th step: on the fibrage after the roll extrusion, cover glue and roll extrusion, form the pipe outer wall;
The 8th step: the tubing fixed length cutting that will accomplish the 7th step;
The 9th step: will cut the reinforcement port sealing of back tubing one end, the cement slurry for preparing in advance toward the interior injection of the square reinforcement of the tubing other end with grouting equipment;
The tenth step: the tubing of filled with water material-mud is stood to holding up, fixing, cement slurry is solidified, be formed into article tubing.
Described reinforcement cross section is square, trapezoidal, arc or triangle.
After overlapping each other, described reinforcement side extends to form fixed hook up or down.
The invention has the advantages that first: after adopting cement slurry to fill perfusion, adopt the thick steel band of 1mm to make reinforcement, also can reach the performance of the thick reinforcement tubing of 4mm in the market, manufacturing cost reduces greatly; Second: in reinforcement, after the slip casting, can promote the compressive property of tubing greatly; The 3rd: welding back reinforcement has formed an integral body, can strengthen the resistance type performance of tubing greatly; The 4th: fixed hook is divided into two concrete chambeies with the space in the reinforcement, not only can jail, concrete dungeon be caught on, and prevents that tubing is in use loosening, and strengthens the support force of reinforcement; The 5th: after adopting fibrage, the anti-interior pressure of tubing, critical external compressive resistance, the anti-performance of breaking increase greatly, and have promoted the resisting longitudinal power and the non-deformability of tubing; The the 6th: after having adopted fixed hook, make in the reinforcement to combine, form an integral body, reduce the tubing coefficient of thermal expansion and contraction, prevent that simultaneously reinforcement from getting rusty with concrete.

The specific embodiment
Below in conjunction with institute's drawings attached the present invention is described further, preferred embodiment of the present invention is: the production method that the described steel of present embodiment is moulded polynary composite pipe includes following steps:
First step: through modified device with HDPE or PVC plastics strengthen, toughening modifying, and be made into plastics strip 1;
Second step: the hollow reinforcement 2 that steel band is rolled into dual-side indent and mutual overlap joint through steel rolling equipment; And extend upward after the reinforcement side overlaps each other and form fixed hook 3.The cross section of reinforcement can be square, trapezoidal, arc or triangle; Can also be designed to other geometry as required.Fixed hook 3 is used for fixing the cement slurry after solidifying.
Third step:, make reinforcement form an integral body with of the notch welding of continuous welding equipment with recess in the reinforcement bottom;
The 4th step: reinforcement and plastics strip after will welding with the spiral Wiring apparatus are twined the formation inside pipe wall synchronously;
The 5th step: on Wrapping formed tube wall, cover glue, roll extrusion;
The 6th step: covered fiber net or winding fabric strip and roll extrusion on the tube wall of accomplishing the 5th step are close on the tube wall fleece or fabric strip;
The 7th step: on the fibrage after the roll extrusion, cover glue and roll extrusion, form the pipe outer wall;
The 8th step: the tubing fixed length cutting that will accomplish the 7th step;
The 9th step: the reinforcement port sealing that will cut back tubing one end; The cement slurry for preparing in advance with grouting equipment injection in the square reinforcement of the tubing other end; Cement slurry can be concrete commonly used in the market, also can adopt the special concrete perfusion according to the market demand;
The tenth step: the tubing of filled with water material-mud is upright to holding up, fixing, prevent that cement slurry from solidifying the back slump; Through 10 ~ 15 days time, cement slurry is solidified again, be formed into article tubing, can the entrucking transportation.
The embodiment of the above only is the present invention's preferred embodiment, is not to limit practical range of the present invention with this, so the variation that all shapes according to the present invention, principle are done all should be encompassed in protection scope of the present invention.
