Abstract
The utility model discloses a high-density polyethylene (HDPE) double-wall wound corrugated pipe, which comprises a pipeline formed by spirally winding a plate strip, wherein two sides of the plate strip are provided with overlap joints which are spirally wound, and hollow bulges are formed on the plate strip and form corrugated bulges of the pipeline; and the HDPE double-wall wound corrugated pipe is characterized in that reinforcing ribs inclined to the normal of the plate strip are arranged inside the hollow bulges and are connected between the bulges and the bottom of the plate strip. The HDPE double-wall wound corrugated pipe has the advantages that the double-wall corrugated pipe is produced in a wound type instead of an extruded type, the construction cost of equipment is low, and a large-caliber pipe is easy to manufacture; the hollow part of the corrugated plate strip is changed into a truss structure, and the ring stiffness of the pipeline can be greatly improved; and moreover, the overlap joints of the plate strip are reinforced, and the pipeline is difficult to crack.
Description
Technical field
The utility model relates to the urban water supply and sewerage facility, particularly a kind of HDPE double-wall winding corrugated pipe.
Background technique
The outstanding advantage that steel is moulded waste pipe is that ring stiffness is high, but many deficiencies are also arranged: 1, because the Young's modulus of plastics and steel differs 200 times, add that the two thermal expansion coefficient also differs 10 times more than, therefore cause the various forms of crackings of tube wall; 2, owing to the poor corrosion resistance of steel, its life-span with plastics is mutually far short of what is expected, in case the steel band place damages, causes pipeline life not high, can not fully show the advantage that the plastics life-span is long; 3, become pipe processing technique complicated; 4, the steel that has is moulded the pipe waste product and can not be recycled.
For this reason, pure HDPE manages particularly that double-wall corrugated pipe has its undeniable advantage.But present double-wall corrugated pipe also has a lot of shortcomings: 1, ring stiffness is not enough; 2, manufacturing equipment is expensive; 3, be difficult to process large diameter pipeline.
The model utility content
The purpose of the utility model is: the deficiency to existing technology provides a kind of HDPE double-wall winding corrugated pipe.
The technological scheme of the utility model is that a kind of HDPE double-wall winding corrugated pipe comprises the pipeline that is entwined by the strip spiral; The both sides of strip are the lap-joint that spiral rolls; The convexity that hollow is arranged on strip, this hollow boss constitute the ripple convexity of pipeline, it is characterized in that; There is the stiffening rib that favours the strip normal direction protruding inside in hollow, and this stiffening rib is connected between convexity and the strip bottom.
The supplementary technology scheme of the utility model is following:
Preferably, the lap-joint that the strip spiral rolls connects through welding, and is externally coated with the PE reinforced layer in lap-joint.
Preferably, said stiffening rib is 2.
Preferably, said stiffening rib is about protruding axis line inside axisymmetric.
Preferably, it is two triangles and a fan-shaped figure that said stiffening rib and protruding wall constitute the cross section, and wherein leg-of-mutton base is positioned on the strip base plane, and fan-shaped arcuate segment is positioned at protruding top.
The beneficial effect of the utility model is: replace extruded type to produce double-wall corrugated pipe with wrap style, equipment manufacturing cost is low, and processes large diameter pipeline easily; Sky makes a kind of truss structure among the waveform strip, can improve the ring stiffness of pipeline greatly; Strip lap-joint strengthens, and pipeline is not easy to crack.
Description of drawings
The utility model will explain through example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the sectional view of the utility model embodiment HDPE double-wall winding corrugated pipe.
Fig. 2 is the sectional view of the sheet material of HDPE double-wall winding corrugated pipe shown in Figure 1.
Embodiment
The specific embodiment 1 of the utility model; A kind of HDPE double-wall winding corrugated pipe as shown in Figure 1 comprises the pipeline that is entwined by strip 1 spiral, and the both sides of strip 1 are the lap-joint 2 that spiral rolls; After strip 1 was rolled into pipeline, adjacent lap-joint 2 was welded together.For the reinforcing phase lap connects intensity partly, can be at the outside PE reinforced layer 5 that applies of the weld that bond together.As shown in Figure 2, the convexity 3 of hollow is arranged on strip, the ripple of protruding 3 the formation pipelines of this hollow is protruding, in the protruding inside of hollow the stiffening rib 4 that favours the strip normal direction is arranged, and this stiffening rib 4 is connected between convexity and the strip bottom.The stiffening rib 4 that tilts can be so that during the pipeline pressurized, and it is more even that internal stress disperses, and increases the ring stiffness and the working life of pipeline.
In the foregoing description; Preferably stiffening rib 4 is 2; And stiffening rib 4 is about protruding axis line inside axisymmetric; It is two triangles and a fan-shaped figure that said stiffening rib 4 constitutes the cross section with protruding wall, and wherein leg-of-mutton base is positioned on the strip base plane, and fan-shaped arcuate segment is positioned at protruding top.Such triangular structure can be so that protruding inner sub-truss structure be more firm, and the ability of bearing pressure is stronger.
Disclosed all characteristics in this specification, or the step in disclosed all methods or the process except mutually exclusive characteristic and/or the step, all can make up by any way.
Disclosed arbitrary characteristic in this specification (comprising any accessory claim, summary and accompanying drawing) is only if special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, only if special narration, each characteristic is an example in a series of equivalences or the similar characteristics.
The utility model is not limited to aforesaid embodiment.The utility model expands to any new feature or any new combination that discloses in this manual, and the arbitrary new method that discloses or step or any new combination of process.
Claims (5)
