Abstract
The invention discloses a production method of a steel plastic concrete composite wound pipe. The method comprises the following steps of: a, producing a coiled plastic board strip with designed shape; b, winding the plastic board strip and mutually sticking the side walls of the plastic board strip or mutually lapping and sticking the edges of the plastic board strip; c, winding a steel strip and embedding the wound steel strip into a plastic board strip clamping groove, and cutting the steel strip into sections after a set length is achieved; d, fixedly connecting a netlike steel bar on the periphery of the formed spiral steel strip; e, coating glue on the plastic board strip, the netlike steel bar and the steel strip; and f, pouring cement mortar into the cavity of the steel strip, the cavity of the plastic board strip or the cavity formed by the steel strip and the plastic board strip together. The pipe produced by the method has strong integral performance and high tensile strength, bending strength and impact strength; the service life of the pipe can reach over 50 years; and the pipe can bear high internal pressure and external pressure, has wide application range, can be used as a water supply pipe, a gas supply pipe, an oil pipe and a jacking pipe, and is widely applied to a water supply and drainage system, a gas supply system and a crude oil delivery system.
Description
Technical field
The present invention relates to a kind of production method of composite pipe, especially the steel used of discharge pressure liquid, gas is moulded the concrete composite tube production method.
Background technique
At present, the plastics strip of various steel plastic composite structure wall waste pipes all is a hollow, though advantage in light weight, conservation is arranged, can not carry liquid, gas with big pressure, can only use narrow in application range as waste pipe.In addition; Be rigidly connected owing to be wound into not have between the spiral steel band zone circle; Therefore the rigidity that adds steel band, plastics strip itself is not enough, has that tensile strength is low, the defective of bend resistance ability, and excessive tensile force or bending power make the body cracking easily or fractures.In a word, there is low, the defective of internal pressure-resistant not of intensity.
Summary of the invention
The purpose of this invention is to provide a kind of steel and mould concrete composite winding pipe material production method, accomplish that the tubing of producing can bear bigger interior pressure, and tensile strength is high, the bend resistance ability is strong.
Production stage of the present invention is following:
1, the plastics strip with designing shape of at first production rolling.
2, adopt spiral Wiring apparatus coiling plastics strip and, or the rim of plastics strip is overlapped bonding formation inner tube wall each other the mutual bonding formation inner tube wall of plastics strip sidewall.
3, with steel coil strip around with embed in the plastics strip draw-in groove, when steel coil strip when embedded length reaches every pipe joint road preseting length, with cutting machine steel band and plastics strip are together cut into joint.
4, constituting on the spiral steel band periphery fixing parallel to an axis steel bar parallel to each other and equally distributed more than 4, parallel to an axis steel bar and each steel band zone circle intersection are welded with the spot welding mode or are affixed with tap bolt; The two ends of two oblique steel bars are intersected respectively be welded on the outer end of per two adjacent parallel to an axis steel bars, promptly the parallel to an axis steel bar is intersected serial connection and constitute netted steel bar with oblique steel bar.
5, on plastics strip, netted steel bar and steel band periphery, cover glue, form plastic layer pipe outer wall.
6, with the past steel band cavity of grouting equipment, cement injection mortar in the common cavity that forms of plastics strip cavity or steel band and plastics strip, the proportioning of slush is a cement: sandstone: water=3: 1: 2.
7, treat that slush is solidified after, obtain finished product.
Compared with present technology, the present invention has following characteristics:
1, because the interconnect function of netted steel bar makes all zone circles of steel band of spirality be fixed into cylindrical shape integral body; Deliquescing is connected to and is rigidly connected; Integrity is strong; Add and be perfused with concrete steel band or the plastics strip has extremely strong rigidity, so the stretch-proof of this composite pipe, bend resistance and impact resistance intensity are high especially, have basically no fracture, phenomenon fractures.The tubing of producing reaches more than 50 years working life.
3, since netted steel bar to the solid effect of increasing of spirality steel band, therefore, the tubing of production can bear bigger interior pressure and external pressure; Using scope is wide; Can be used as water supply, air feed and transport pipe and use, also can do pipe use in advance, be widely used in supply and drain water system, air supply system and Crude Oil Transportation system.
