Abstract
A dual-wall corrugated pipe has the corrugated-typed external wall. The utility model is characterized in that the wave crest position of the corrugated-typed external wall is in round arc shape of arc transitional angle. The wave crest position and the transitional angle integration of the utility model are round arc structure with uniform wall thickness, and largely reinforce the capability of anti-impact of the external force. Meanwhile, as the round arc transition is adopted, the transitional angle is slippery and smooth; in the production process of no corners, the flow of the material is smooth, the corrugated shape of the pipe is nice and consistent, which greatly improves the quality and performance of the pipe.
Description
Technical field:
The utility model relates to pipe fitting.More particularly, the especially underground double-wall corrugated pipe of burying usefulness underground.
Double-wall corrugated pipe is selected rigid polyvinyl chloride (PVC-U) extruding and moulding for use.Having different many advantages such as inner wall smooth, discharge value be big, in light weight, corrosion-resistant, is the underground best substitute of burying various tubing underground.Be mainly used in underground draining, the blow-off line buried underground in residential quarters at present; High voltage cable, post and telecommunications cable cover(ing); The pre-buried pipeline of expressway circuit; Farmland, water conservancy irrigation water delivery, water drainage; Chemical industry, mine are used for the conveying of fluid or solid etc.But, find following problem in the practical application: the corrugated outer wall shape of original tubing as shown in Figure 2, its crest section is too straight, the crest plane is long, the transition angular position has " turning " to exist, and causes wall unevenness even, and has bigger internal stress at place, transition angle.Make tubing bury underground in the process in transportation and installation, as easily damaged when being subjected to the external world and having the object hard collision of sharp keen wedge angle, cause the damage of tubing ripple.Simultaneously, this form structure in process of production, Flow of Goods and Materials is not smooth.When interlayer air pressure is unstable, can cause the inconsistent of ripple profile, influence outward appearance and quality of product.
Summary of the invention:
Technical problem to be solved in the utility model is: a kind of double-wall corrugated pipe is provided, and its external shock resistance ability is strong, ripple beautiful shape unanimity.
The technological scheme that the utility model technical solution problem is taked is: the crest position of corrugated outer wall is designed to circular shape by circular arc transition angle transition.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
Crest position in the utility model and transition angle integral body are circular shape, and wall thickness is even, have strengthened the ability that its external force resistance impacts greatly.Simultaneously, owing to adopt the circular arc transition, its transition angle slyness is smooth, and in the production process formula, Flow of Goods and Materials is smooth and easy, and the bellows-shaped of tubing unanimity attractive in appearance can greatly be improved the quality of products and performance.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the prior art structural representation.
Embodiment:
Shown in Figure 1, the inwall 1 of double-wall corrugated pipe is straight pipeline section, and outer wall 2 is corrugated, is interlayer therebetween.In the present embodiment, the crest position of corrugated outer wall 2 is the circular shape by circular arc transition angle transition.Outer wall 2 ripple slynesses are smooth, do not have at " turning ", and wall thickness is even.
Claims (1)
1, double-wall corrugated pipe has corrugated outer wall (2), it is characterized in that, the crest position of described corrugated outer wall (2) is the circular shape by circular arc transition angle transition.
