Abstract

The utility model provides a plastic double-wall corrugated pipeline. According to the plastic double-wall corrugated pipeline, corrugated peaks or valleys of the plastic double-wall corrugated pipeline are provided with strengthening beams, wherein the width of the strengthening beams is 1/20 to 2/3 of the width of the corrugated peaks, and the width of the strengthening beams is also 1/20 to 2/3 of the width of the corrugated valleys. Because the corrugated peaks or valleys of the plastic double-wall corrugated pipeline are provided with the strengthening beams, the ring stiffness is increased, and the requirement on high ring stiffness of special projects to the plastic pipeline can be met.

Description

The double-wall corrugated pipeline of a kind of plastic cement

Technical field

The utility model relates to plastic cement pipeline field, relates in particular to the double-wall corrugated pipeline of a kind of plastic cement.

Background technique

The structure of the double-wall corrugated pipeline of existing plastic cement; As shown in Figure 1, its inwall is level and smooth, in order to increase the anti-pressure ability of plastic cement pipeline; The double-wall corrugated pipeline outer wall of the plastic cement of existing technology is a bellows-shaped, and the trough of outer wall and inwall are united through extrusion bonded formation of high temperature together.But the double-wall corrugated pipeline of this plastic cement of the prior art, when special engineering was higher to the pipe ring rigidity requirement, this pipeline can't meet the demands.

The model utility content

The purpose of the utility model provides the double-wall corrugated pipeline of a kind of plastic cement, can improve the withstand voltage degree of double-wall corrugated pipeline in the existing technology.

In order to solve the problems of the technologies described above, the double-wall corrugated pipeline of the plastic cement that the utility model provides is achieved in that

The double-wall corrugated pipeline of a kind of plastic cement, at the ripple crest of the double-wall corrugated pipeline of said plastic cement or/and trough is provided with buttress brace.

Optional, the width of said buttress brace is 1/20～2/3 of a said ripple crest width, the width of said buttress brace is 1/20～2/3 of a said ripple trough width.

Optional, the section of said buttress brace is trapezoidal, rectangle, parabola shaped, oval, hyperbola or circular arc.

Optional, said buttress brace is a hollow or solid.

Optional, the double-wall corrugated pipeline of said plastic cement is by PVC or polyvinyl chloride modifying material, high density polyethylene (HDPE) or high-density polyethylene modified material, polyethylene or polyethylene modified material, or polypropylene or polypropylene modified material are processed.

The double-wall corrugated pipeline of the plastic cement that the utility model provides or/and trough is provided with buttress brace, does not have the plastic cement double-wall corrugated pipeline of buttress brace with respect to existing technology at crest, and ring stiffness increases, and can satisfy special engineering to the high demand of plastic cement pipe ring rigidity requirement.

Further; The double-wall corrugated pipeline of the plastic cement that the utility model provides; The width of buttress brace is 1/20～2/3 of a ripple crest width, and the width of buttress brace is 1/20～2/3 of a ripple trough width, and width can not surpass the width of crest or trough; According to the buttress brace of special engineering, save cost when satisfying requirement of engineering to the different requirement making different in width of ring stiffness.

Further, buttress brace is a hollow, and this structure can improve the ring stiffness of plastic cement pipeline, can also save cost simultaneously.

Embodiment

Clear more bright 1 for the purpose, technological scheme and the advantage that make the utility model, below in conjunction with accompanying drawing and embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Like Fig. 4, Fig. 5 and shown in Figure 6; The double-wall corrugated pipeline of the plastic cement that the utility model provides; Or/and trough is provided with buttress brace 1, can only buttress brace be set at the ripple crest of the double-wall corrugated pipeline of plastic cement, also can only buttress brace be set at trough at crest; If ring stiffness is required height, can at crest and trough buttress brace be set simultaneously.

The width that is arranged on the buttress brace 1 of crest is 1/20～2/3 of a ripple crest width, and the width that is arranged on the buttress brace 1 of trough is 1/20～2/3 of a ripple trough width.According to the engineering demands of different, the width of buttress brace 1 is set, can satisfy requirement of engineering, also save cost.

The section configuration of buttress brace 1 is trapezoidal, rectangle, parabola shaped, oval, hyperbola or circular arc, and the utility model does not limit the section configuration of buttress brace.

And buttress brace 1 can be set be hollow or solid, the structure of hollow can improve the ring stiffness of plastic cement pipeline, can also save cost simultaneously.

The double-wall corrugated pipeline of plastic cement is by PVC (PVC; Polyvinyl chloride polymer) or polyvinyl chloride modifying material, high density polyethylene (HDPE) (HDPE; High Density Polyethylene) or high-density polyethylene modified material, polyethylene (PE; Polyethylene) or polyethylene modified material, or polypropylene (PP, Polypropylene) or engineering plastics material such as polypropylene modified material process; The utility model does not limit the material of the double-wall corrugated pipeline of plastic cement making the utility model and provide, and those skilled in the art can select the engineering plastics material that is fit to as required.

The scheme of the utility model can be applied to the single-wall corrugated pipe road equally.

The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
