Abstract
A strengthening polyethylene spiral corrugated pipe with a steel belt comprises an inner plastic pipe; a forming steel belt with outer flanges at two edges is wound on the outer surface of the inner plastic pipe at equal intervals; the outer flanges of the two adjacent circles of forming steels belt are laminated and overlapped together; a connecting steel belt is wound between the two adjacent circles of forming steel belts; and the connecting steel belt is overlapped on the outer flanges of the two adjacent circles of forming steel belts. The integral strength of the pipe wall is greatly improved, the two adjacent circles of forming steel belts are not easy to damage and leak, and the application range of the spiral corrugated pipe with the plastic steel belt is widened.
Description
Technical field
The utility model relates to the tubing technical field, particularly relates to a kind of steel band reinforced polyethylene spiral ripple pipe.
Background technique
Plastics ribbon spiral bellows is owing to have ring stiffness height, easy to connect a, low cost and other advantages, and what be used as field such as urban construction at present more and more buries ground draining, blow-off line.Existing plastics ribbon spiral bellows is when tube forming; Keep at a certain distance away between the two adjacent rings steel band, promptly plastic inner pipe exposes between the two adjacent rings steel band, has reduced the bulk strength of tube wall; When in use receiving the impact of sharp objects; Cause tube wall to break and seepage easily, influence working life, limited its application area.
Summary of the invention
The purpose of the utility model is exactly that the steel band reinforced polyethylene spiral ripple pipe that a kind of tube wall bulk strength is high, be difficult for breaking will be provided.
A kind of steel band reinforced polyethylene spiral ripple pipe; Comprise plastic inner pipe; Be wound with the shaped-steel strip that both sides have flanging in that the outer surface of plastic inner pipe is equidistant; The flanging of two adjacent rings shaped-steel strip laminates and overlaps, and is wound with the connection steel band between the two adjacent rings shaped-steel strip, connects the steel band pressure on the flanging of two adjacent rings shaped-steel strip.
Described shaped-steel strip is that both sides the U-shaped profiled strip that has a flanging and the inner plastic layer and the outer plastic layer that are coated on the profiled strip both sides constitute by sectional shape, and inner plastic layer and plastic inner pipe outer wall are bonded together.
The outside of described connection steel band is coated with plastic layer, and the outer plastic layer of these plastic layer both sides and shaped-steel strip is bonded together.
Compared with prior art, the advantage of the utility model is:
Because the shaped-steel strip of the utility model laminates winding successively; The both sides that promptly constitute the shaped-steel strip of helical corrugation overlap, and plastic inner pipe is all coated by steel band, also is wound with the connection steel band between the two adjacent rings shaped-steel strip; Connect steel band both sides pressure on the flanging of shaped-steel strip; Plastic inner pipe is all coated by steel band, thereby it has also improved the bulk strength of tube wall greatly except all advantages with existing plastics ribbon spiral bellows; Make between the two adjacent rings shaped-steel strip not cracky seepage, enlarged the application area of plastics ribbon spiral bellows.
Description of drawings
Fig. 1 is the longitudinal sectional drawing of the utility model;
Fig. 2 is the joint sectional drawing of two adjacent rings shaped-steel strip.
Embodiment
Like Fig. 1-2 illustrated embodiment; The utility model adopts the hot extrusion winding shaping process to make, and promptly is wound with the shaped-steel strip that both sides have flanging in that the outer surface of the plastic inner pipe 1 of hot extrusion moulding is equidistant, and is as shown in Figure 2; It is the enlarged view of A part among Fig. 1; Shaped-steel strip comprises that the sectional shape that has flanging is the profiled strip 3 of U type or Ω shape, is coated with inner plastic layer 5 and outer plastic layer 2 in profiled strip 3 both sides, inner plastic layer 5 and bonding being fixed together of plastic inner pipe 1 outer wall.In the time of Wrapping formed steel band; Make the flanging of profiled strip 3 laminate overlap joint; Thereby improved the intensity of shaped-steel strip junction point, between the two adjacent rings shaped-steel strip, also be wound with flat connection steel band 4, connected steel band 4 both sides pressures on the flanging of profiled strip 3.The outside that connects steel band 4 is coated in the outer plastic layer 2.
Claims (3)
1. steel band reinforced polyethylene spiral ripple pipe; Comprise plastic inner pipe; Be wound with the shaped-steel strip that both sides have flanging in that the outer surface of plastic inner pipe is equidistant, it is characterized in that the flanging of two adjacent rings shaped-steel strip laminates and overlaps; Be wound with the connection steel band between the two adjacent rings shaped-steel strip, connect the steel band pressure on the flanging of two adjacent rings shaped-steel strip.
2. steel band reinforced polyethylene spiral ripple pipe according to claim 1; It is characterized in that; Described shaped-steel strip is that both sides the U-shaped profiled strip that has a flanging and the inner plastic layer and the outer plastic layer that are coated on the profiled strip both sides constitute by sectional shape, and inner plastic layer and plastic inner pipe outer wall are bonded together.
3. steel band reinforced polyethylene spiral ripple pipe according to claim 2 is characterized in that the outside of described connection steel band is coated with plastic layer, and the outer plastic layer of these plastic layer both sides and shaped-steel strip is bonded together.
