But, there is following defect in double-wall corrugated pipe in the market: 1, the waveform of existing double-walled corrugated tube is independent wave mode, its physical and mechanical property as ring stiffness, that ring is flexible, impact resistance is difficult to balance is up to standard, indices must be made qualified by adjustment production technology and composition of raw materials, thus cause production capacity low high with cost; 2, the crest place wall thickness of existing double-walled corrugated tube is less than the wall thickness at other positions, and its physical and mechanical property has to be hoisted; 3, because the socket wall thickness of its large enlarging only has 3-6mm, and the external diameter of bellmouth is greater than the external diameter of crest, carrying, stack and in installation process bellmouth yielding or break, easily cause waste; 3, because its large enlarging place wall thickness only has 3-6mm, and the external diameter of large enlarging is greater than the external diameter of crest, carrying, stack and in installation process large enlarging yielding or break, easily cause waste; 4, line seal performance has to be hoisted; 5, because large enlarging module empty avoiding calibration sleeve size is comparatively large, more consuming time in production technology operating process, enlarging and tubing cool asynchronous, and manufacturing efficiency has to be hoisted.
The problem such as to have much room for improvement for the traditional double-wall corrugated pipe complex manufacturing described in above-mentioned correlation technique, physical and mechanical property, not yet propose effective solution at present.
Model utility content
For problems such as traditional double-wall corrugated pipe complex manufacturing above-mentioned in correlation technique, physical and mechanical property have much room for improvement, the utility model proposes a kind of dual damascene structure wall pipe, rational in infrastructure, production technology is simple and physical and mechanical property is high.
The technical solution of the utility model is achieved in that
A kind of buried plastics dual damascene structure wall pipe, comprise body, described body comprises internal and external layer bound site, and described internal and external layer bound site side is one-body molded is provided with pipe tail internal and external layer bound site, and the opposite side of described internal and external layer bound site is provided with integrated flat enlarging; Described pipe tail internal and external layer bound site is provided with the socket dual ripple crest matched, and described internal and external layer bound site is provided with the outer dual ripple crest matched, and the external diameter of described outer dual ripple crest is identical with the external diameter of described flat enlarging; Further, described inboard wall of tube body is smooth internal walls.
Further, the external diameter of described socket dual ripple crest is less than the external diameter of described outer dual ripple crest.
Further, described pipe tail internal and external layer bound site is 0.3m ~ 0.5m together with the length of socket dual ripple crest, and described internal and external layer bound site is 5.5m ~ 5.8m together with the length of dual ripple crest.
Further, the number of described socket dual ripple crest is 3-5, and the number of described outer dual ripple crest is 60-120.
Further, the material of described buried plastics dual damascene structure wall pipe comprises PP-HM (polypropylene), HDPE (high density polyethylene (HDPE)) and PVC-U (PVC＝polyvinyl chloride).
The beneficial effects of the utility model: rational in infrastructure, physical mechanics (ring just/ring is soft/impact) performance is high, and production technology is simple, can save production cost, reduce tubing breakage waste, improve line seal performance, thus make this buried plastics dual damascene structure wall pipe have more wide market prospects.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of a kind of buried plastics dual damascene structure wall pipe according to the utility model embodiment.
In figure:
1, internal and external layer bound site; 2, outer dual ripple crest; 3, pipe tail internal and external layer bound site; 4, flat enlarging; 5, socket dual ripple crest.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain, belongs to the scope of the utility model protection.
As shown in Figure 1, according to the one of the utility model embodiment buried plastics dual damascene structure wall pipe, comprise body, described body comprises internal and external layer bound site 1, described internal and external layer bound site 1 side is one-body molded is provided with pipe tail internal and external layer bound site 3, and the opposite side of described internal and external layer bound site 1 is provided with integrated flat enlarging 4; Described pipe tail internal and external layer bound site 3 is provided with the socket dual ripple crest 5 matched, and described internal and external layer bound site 1 is provided with the outer dual ripple crest 2 matched, and the external diameter of described outer dual ripple crest 2 is identical with the external diameter of described flat enlarging 4; Further, described inboard wall of tube body is smooth internal walls.
