Abstract
The utility model discloses an enhanced plastic double-wall corrugated pipe which comprises a corrugated outer wall and a cylindrical corrugated inner wall. The corrugated outer wall is composed of crest sections and trough sections, wherein the crest sections and the trough sections are arranged alternately along the axial direction, reinforcing plates are arranged on the shoulder portions on two sides of the top of each crest section, and each reinforcing plate is circular in the whole. An inner reinforcing plate is arranged on a joint of each crest section and each trough section, and the inner reinforcing plate is circular in the whole. By means of the above technical scheme, strength of the crest sections can be enhanced fully, ring stiffness of an entire pipe is further enhanced greatly, and the requirement that a special project has high ring stiffness demand on a plastic corrugated pipe is met fully.
Description
Technical field
The utility model relates to a kind of pipeline, relates in particular to a kind of enhancement mode plastic cement double-wall corrugated pipe.
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 is had relatively high expectations in special engineering, the double-wall corrugated pipeline of the plastic cement of this structure will be crushed, because the crest section is hollow structure, the position of easy flattening deformation just is the shoulder of ring and the joint between crest section and the trough section in both sides, crest section top, and this just 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: a kind of enhancement mode plastic cement double-wall corrugated pipe, comprise ripple outer wall and columnar ripple inwall, the ripple outer wall is made up of crest section and the trough section of alternately arranging vertically, and the shoulder of the both sides, top of described each crest section is respectively equipped with the outer stiffening plate that one integral body is ring.
Be equipped with the whole interior stiffening plate that is ring in the crest section with trough section joint.
The outer stiffening plate of described per pass is continuous cirque structure or the cirque structure that is made of the disconnected outer arcuate plate of at least two internodes.
Stiffening plate is continuous cirque structure or the cirque structure that is made of the disconnected arc plate of at least two internodes in the described per pass.
Described outer stiffening plate, interior stiffening plate and ripple outer wall are one-body molded.
Have two axial mould closed lines of symmetry on the described ripple outer wall, two the axial mould closed lines in ripple outer wall upper edge are respectively equipped with axial stiffening plate or shaft orientation reinforcing rib.
Described axial stiffening plate is the disconnected structure of continuous structure or at least two internodes.
Described shaft orientation reinforcing rib is the disconnected structure of continuous structure or at least two internodes.
Described each crest section is equipped with the ring stiffening rib one along center of top, and described ring stiffening rib is the disconnected structure of continuous structure or at least two internodes.
Adopt technique scheme, shoulder in the both sides, top of each crest section of ripple outer wall is respectively equipped with the outer stiffening plate that one integral body is ring, be equipped with the whole interior stiffening plate that is ring in the crest section with trough section joint, so just fully increased the intensity of crest section, the ring stiffness of whole pipe is strengthened greatly, fully satisfy special engineering to the demanding demand of plastic cement corrugated conduit ring stiffness.The external frame of outer stiffening plate and interior stiffening plate cross section is curved section shape all, can increase the bonded area with crest section and trough section outer surface like this, strengthens the intensity of crest section.Outer stiffening plate, interior stiffening plate and ripple outer wall are one-body molded, are convenient to designing mould and manufacturing like this.According to the different requirements of special engineering to the double-wall corrugated pipeline ring stiffness of plastic cement, can per pass outer stiffening plate and the interior stiffening plate cirque structure that is set to continuous cirque structure or constituted by the disconnected arc plate of at least two internodes, like this can economical with materials and reduce cost.Because when making double-wall corrugated pipe, two axial mould closed line places are weak link, therefore in axial mould closed line axial stiffening plate or shaft orientation reinforcing rib are set, can fully strengthen the intensity at this place.

Fig. 2 is the central wherein joint ripple outer wall of Fig. 1 and the axial cutaway view Amplified image of ripple inwall.
Embodiment
As depicted in figs. 1 and 2, a kind of enhancement mode plastic cement double-wall corrugated pipe of the present utility model, comprise ripple outer wall and columnar ripple inwall 5, the ripple outer wall is made up of crest section 1 and the trough section 2 of alternately arranging vertically, and the shoulder of the both sides, top of each crest section 1 is respectively equipped with the outer stiffening plate 3 that one integral body is ring.Be equipped with the whole interior stiffening plate 4 that is ring in crest section 1 with trough section joint, the external frame of outer stiffening plate 3 and interior stiffening plate 4 cross sections is curved section shape all, and namely outer stiffening plate 3 and interior stiffening plate 4 are the curved surface platy structure.So just fully increase the intensity of crest section 1, the ring stiffness of whole pipe is strengthened greatly, fully satisfied special engineering to the demanding demand of plastic cement corrugated conduit ring stiffness.Outer stiffening plate 3, interior stiffening plate 4 and ripple outer wall are one-body molded, are convenient to designing mould and manufacturing like this.Outer stiffening plate 3 and interior stiffening plate 4 can be done local thickening, and particularly the concave surface place of the convex surface of stiffening plate 3 and interior stiffening plate 4 thickeies processing outside, and this comprises that also the triangle gusset is set to be strengthened handling.
Have two axial mould closed lines of symmetry on the ripple outer wall, two the axial mould closed lines in ripple outer wall upper edge are respectively equipped with axial stiffening plate 6(or shaft orientation reinforcing rib).Axial stiffening plate 6(or shaft orientation reinforcing rib) be the disconnected structure of continuous structure or at least two internodes.
Each crest section 1 is equipped with ring stiffening rib 7 one along center of top, and described ring stiffening rib 7 is the disconnected structure of continuous structure or at least two internodes.
According to the different requirements of special engineering to the double-wall corrugated pipeline ring stiffness of plastic cement, can be continuous cirque structure or the cirque structure that is made of the disconnected outer arcuate plate of at least two internodes with the outer stiffening plate 3 of per pass, stiffening plate 4 be continuous cirque structure or the cirque structure that is made of the disconnected arc plate of at least two internodes in the per pass.Can save plastic material like this and reduce cost.Because when making double-wall corrugated pipe, two axial mould closed line places are weak link, therefore in axial mould closed line axial stiffening plate 6(or shaft orientation reinforcing rib are set), can fully strengthen the intensity at this place.
