Abstract
The utility model provides a PVC U double -walled bellows to interior outer bellows, skeleton back up coat, heat preservation and the interior straight tube of including in proper order outside from, is provided with reinforcing frame among the protruding ring of outer bellows, the inner wall of interior straight tube is smooth. The utility model discloses increased skeleton back up coat and heat preservation between bellows and the interior straight tube outside, increased the utility model discloses an intensity and thermal insulation performance can effectually prevent that the body from being destroyed by external shock power to intraductal water is difficult to freeze, in addition, be provided with reinforcing frame among the protruding ring of bellows outside, further strengthened the intensity of body.
Description
Technical field
This utility model relates to corrugated tube, particularly to PVC-U double-wall corrugated pipe.
Background technology
Existing double-wall corrugated pipe selects polrvinyl chloride (PVC-U) extrusion molding.There is inner wall smooth, stream
The advantages such as flux is big, lightweight, corrosion-resistant, are the best substitute of the various tubing of embedded underground.
But in use, due to the uneven sink-float of soil, PVC-U double-wall corrugated pipe can be caused punching
Hit, once more than the anti-pressure ability of PVC-U double-wall corrugated pipe, PVC-U double-wall corrugated pipe can be caused one
Determine the destruction of degree, affect the service life of PVC-U double-wall corrugated pipe.It addition, its heat insulating ability is poor,
In winter pipe, the water capacity easily freezes, and causes corrugated tube by the generation of bursting by freezing phenomenon.
It is thus desirable to design a kind of structural strength height and the PVC-U double-wall corrugated pipe of energy frost-cracking-preventing.
Utility model content
The utility model proposes PVC-U double-wall corrugated pipe, solve existing PVC-U double-wall corrugated pipe strong
Degree deficiency, the defect of the water capacity easily icing bursting by freezing body in winter pipe.
The technical solution of the utility model is achieved in that
PVC-U double-wall corrugated pipe, include the most successively outward corrugated tube, skeleton back-up coat, heat-insulation layer and
Interior straight tube, is provided with strengthening frame, the inner wall smooth of interior straight tube in the protruding ring of outward corrugated tube.
Further, described skeleton back-up coat is steel plate or steel mesh.
Further, described strengthening frame is curved plate or steel mesh.
Further, described heat-insulation layer is asbestos gauge.
Further, described outward corrugated tube and interior straight tube are polrvinyl chloride material.
The beneficial effects of the utility model: this utility model adds skeleton between outward corrugated tube and interior straight tube
Back-up coat and heat-insulation layer, add intensity of the present utility model and heat-insulating property, can effectively prevent body quilt
External impact force is destroyed, and in pipe, water is not easy to freeze；It addition, arrange in the protruding ring of outward corrugated tube
There is strengthening frame, further enhance the intensity of body.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below by right
In embodiment or description of the prior art, the required accompanying drawing used is briefly described, it should be apparent that below,
Accompanying drawing in description is only embodiments more of the present utility model, for those of ordinary skill in the art,
On the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of this utility model PVC-U double-wall corrugated pipe.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical side in this utility model embodiment
Case is clearly and completely described, it is clear that described embodiment is only that this utility model part is real
Execute example rather than whole embodiments.Based on the embodiment in this utility model, ordinary skill people
The every other embodiment that member is obtained under not making creative work premise, broadly falls into this utility model
The scope of protection.
With reference to Fig. 1, PVC-U double-wall corrugated pipe, include outward corrugated tube 1, skeleton back-up coat the most successively
2, heat-insulation layer 3 and interior straight tube 4, is provided with strengthening frame 6, interior straight tube 4 in the protruding ring 5 of outward corrugated tube 1
Inner wall smooth.Skeleton back-up coat 2 can select steel plate or steel mesh, can also select it the most as required
He, as long as playing reinforcement body intensity purpose.Strengthening frame 6 can select curved plate or steel mesh,
Can also be selected other.The preferred asbestos gauge of heat-insulation layer 3, asbestos gauge good heat insulating, cost is the lowest, certainly
The most do not limit other insulation material.This utility model adds bone between outward corrugated tube 1 and interior straight tube 4
Frame back-up coat 2 and heat-insulation layer 3, add intensity of the present utility model and heat-insulating property, can effectively prevent pipe
Body is destroyed by external impact force, and in pipe, water is not easy to freeze；It addition, at the protruding ring of outward corrugated tube 1
In 5 be provided with strengthening frame 6, further enhance the intensity of body.
Preferably, described outward corrugated tube 1 and interior straight tube 4 are polrvinyl chloride material.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model,
All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all
Within protection domain of the present utility model should be included in.
