Abstract
The utility model discloses a plastic double-wall corrugated pipeline which comprises a corrugated outer wall. The corrugated outer wall is formed by crest sections and trough sections. The crest sections and the trough sections are alternately arranged along the axial direction. A protruding ring which is integrally in a circular ring shape is arranged on the top of each crest section. The wall thickness of each protruding ring is identical to the wall thickness of the each crest section. Through adoption of the technical scheme, the protruding ring which is integrally in a circular ring shape is arranged on the top of each crest section on the outer wall of the corrugated pipeline. Consequently, the strength of the crest sections is enhanced, and the ring stiffness of the whole pipeline is also greatly strengthened. The plastic double-wall corrugated pipeline fully meets the requirements of a special project for the high ring stiffness of the plastic corrugated pipeline.
Description
Technical field
The utility model relates to a kind of pipeline, relates in particular to the double-wall corrugated pipeline of a kind of plastic cement.
Background technique
The double-wall corrugated pipeline of existing plastic cement is that inwall is level and smooth, outer wall is the structure of bellows-shaped, and extrusion bonded by high temperature between the trough section of outer wall and the inwall is one.When ring stiffness was had relatively high expectations in special engineering, the double-wall corrugated pipeline of the plastic cement of this structure will be crushed, can't engineering demands.
The model utility content
The utility model is in order to solve deficiency of the prior art, and a kind of ring stiffness height, the double-wall corrugated pipeline of plastic cement that compression resistance is strong are provided.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: the double-wall corrugated pipeline of a kind of plastic cement, comprise the ripple outer wall, the ripple outer wall is made up of crest section and the trough section of alternately arranging vertically, the top of described each crest section is equipped with the convex type ring that one integral body is ring, and the wall thickness of the wall thickness of convex type ring and crest section is suitable.
Described convex type ring and ripple outer wall are one-body molded, convex type ring both sides and the transition of crest section surface curve smoothing.
Described per pass convex type ring is continuous cirque structure or the cirque structure that is made of the disconnected arc of at least two internodes.
Adopt technique scheme, be equipped with one integral body at the top of each crest section of ripple outer wall and be the convex type ring of ring, increase the intensity of crest section, the ring stiffness of whole pipe is strengthened greatly, fully satisfied special engineering to the demanding demand of plastic cement corrugated conduit ring stiffness.The wall thickness of the wall thickness of convex type ring and crest section is suitable, and namely the convex type ring inner ring has the groove of ring, can reduce material consumption like this.Convex type ring and ripple outer wall are one-body molded, and designing mould and manufacturing are convenient in convex type ring both sides and the transition of crest section surface curve smoothing like this.According to the different requirements of special engineering to plastic cement corrugated conduit ring stiffness, the cirque structure that can the per pass convex type ring be set to continuous cirque structure or be constituted by the disconnected arc of at least two internodes.Like this can economical with materials and reduce cost.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is the axial cutaway view Amplified image of the ripple outer wall in the middle of Fig. 1.
Embodiment
As depicted in figs. 1 and 2, the double-wall corrugated pipeline of a kind of plastic cement of the present utility model comprises the ripple outer wall, and the ripple outer wall is made up of crest section 1 and the trough section 2 of alternately arranging vertically, and the top of each crest section 1 is equipped with the convex type ring 3 that one integral body is ring.The wall thickness of the wall thickness of convex type ring 3 and crest section 1 is suitable, it is the groove 4 that convex type ring 3 inner rings have ring, this has not only saved material consumption, also increased the intensity of crest section 1, the ring stiffness of whole pipe is strengthened greatly, fully satisfy special engineering to the demanding demand of plastic cement corrugated conduit ring stiffness.
Convex type ring 3 is one-body molded with the ripple outer wall, and convex type ring 3 both sides and crest section 1 surface curve seamlessly transit, and are convenient to designing mould and manufacturing like this.
According to the different requirements of special engineering to plastic cement corrugated conduit ring stiffness, per pass convex type ring 3 is continuous cirque structure, and the perhaps cirque structure that is made of the disconnected arc of at least two internodes like this can economical with materials and reduce cost.
