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 height, bend resistance ability are strong.
Production stage of the present invention is as follows:
1, the plastics strip with design 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 inside pipe wall mutually the mutual bonding formation inside pipe 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, fix axially parallel steel bar parallel to each other and equally distributed more than 4 on the spiral steel band periphery constituting, axially parallel 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 axially parallel steel bars, promptly the axially parallel 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 concrete pump, cement injection mortar in the common cavity that forms of plastics strip cavity or steel band and plastics strip, the proportioning of cement mortar is a cement: sandstone: water=3: 1: 2.
7, treat that cement mortar is solidified after, obtain finished product.
Compared with the prior art, the present invention has following characteristics:
1, because the connection effect 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, globality is strong, add and be perfused with concrete steel band or the plastics strip has extremely strong rigidity, therefore stretch-proof, bend resistance and the impact resistance intensity of this composite pipe are high especially, and essentially no fracture, phenomenon fractures.The tubing of producing reaches more than 50 years service 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, the scope of application is wide, can be used as water supply, air feed and petroleum pipeline and use, also can make pre-pipe and use, be widely used in supply and drain water system, air supply system and Crude Oil Transportation system.
