Set up the I shape elastic component through the high spot in the cavity, further improve compressive capacity.
Description
Technical field
This utility model belongs to tubing technical field, particularly relates to a kind of PVC-U (PVC-U) riffled tube.
Background technology
PVC-U (PVC-U) riffled tube is by the heated extrusion of polyvinyl chloride resin, uses another novel PVC-U pipeline that special dies and forming technology produce, and it is the product of the hi-tech development nineties in 20th century.This tubing, under identical compression load ability, saves the material of 30% than common PVC-U solid wall pipe.PVC-U riffled tube is basically identical with PVC-U riffled tube purpose of design, actually the one of structure-wall pipe material.As buried draining, blowdown heavy caliber PVC-U pipe, it is mainly used for: under gravity sewage or rainwater etc. is displaced in sewage farm or rivers,lakes and seas, is widely used in municipal engineering construction.Additionally can be additionally used in the fields such as field irrigation, power communication, cable protection and discharge of industrial wastes.
In general, PVC-U riffled tube is often embedded in underground, such as buried drain pipe road, belong to high-line conduit, be primarily subjected to external pressure load (usual intrinsic pressure load is ignored), and the pipeline that existing PVC-U riffled tube is made belongs to flexible pipe, critical external compressive resistance ability, the form destroyed is that external pressure load causes pipe deformations excessive or lateral deflection unstability, has influence on it and extensively applies, particularly in the application of bigger city by a definite limitation.
Utility model content
Therefore, for above-mentioned problem, the utility model proposes the PVC-U riffled tube that a kind of critical external compressive resistance ability is strong, existing reinforcement pipe structure is improved so that it is meet the occasion of various high demand.
In order to solve above-mentioned technical problem, this utility model be employed technical scheme comprise that, a kind of PVC-U riffled tube, and the reinforcement being placed equidistant including polrvinyl chloride body and spiral surrounding polrvinyl chloride body forms cavity between reinforcement and polrvinyl chloride body；Adjacent said rib forms undulatory projection and depression, is provided with I shape elastic component in each projection.I shape elastic component is set by the high spot in cavity, improves anti-pressure ability further.
Preferably, described I shape elastic component is made into integration, and it can be that rubber is made, it is also possible to be that other elastomeric materials are made.
When riffled tube is by external pressure, first pressure arrives reinforcement, pressure in order to make reinforcement decompose is bigger, and itself destruction is little, as a preferred scheme, the vertical section of described reinforcement is isosceles trapezoid, the upper end of isosceles trapezoid and go to the bottom with polrvinyl chloride body axially in parallel.
The pitch of described reinforcement is 1-5cm.Shorter reinforcement pitch, more pressure than existing structure.
Described reinforcement is to be realized by the polyethylene layer of parcel steel band.
Further, the tube wall of described polrvinyl chloride body is hollow structure (tubular structure), and the inside and outside wall of polrvinyl chloride body is smooth structure.The polrvinyl chloride body of tubular structure not only increases the number of plies of tube wall, reduces permeability, and can be used for preventing polrvinyl chloride body and rupture because of extraneous extruding.
This utility model passes through such scheme, has the advantage that
1, I shape elastic component is set by the high spot in cavity, substantially increases voltage endurance capability；
2, this utility model reduces the pitch between reinforcement, thus increases anti-pressure ability；
3, this utility model uses the polrvinyl chloride body of hollow structure, also can prevent the polrvinyl chloride body at center further and rupture because of extraneous extruding, improve overall quality further, extend service life；
4, this utility model is skillfully constructed, simple in construction, it is easy to accomplish, it is simple to industrialization produces, and has good practicality.
Accompanying drawing explanation
Fig. 1 is the sectional view of embodiment of the present utility model.
Detailed description of the invention
In conjunction with the drawings and specific embodiments, this utility model is further illustrated.
As a specific embodiment, see Fig. 1, a kind of PVC-U riffled tube of the present utility model, the reinforcement 2 being placed equidistant including polrvinyl chloride body 1 and spiral surrounding polrvinyl chloride body 1, between reinforcement 2 and polrvinyl chloride body 1, form cavity；Adjacent said rib 2 forms undulatory protruding 3 and caves in, and is provided with I shape elastic component in each protruding 3.
When riffled tube is by external pressure, first pressure arrives reinforcement 2, pressure in order to make reinforcement 2 decompose is bigger, and itself destruction is little, as a preferred scheme, the vertical section of reinforcement 2 is isosceles trapezoid, the upper end of isosceles trapezoid and go to the bottom with polrvinyl chloride body axially in parallel.It addition, reinforcement 2 is to be realized by the polyethylene layer of parcel steel band.The pitch of reinforcement 2 is 1-5cm.Shorter reinforcement 2 pitch, more pressure than existing structure.
It addition, in order to further enhance toughness, the tube wall of polrvinyl chloride body 1 is a tubular structure (hollow structure), and the inside and outside wall of polrvinyl chloride body 1 is smooth structure.The polrvinyl chloride body 1 of tubular structure not only increases the number of plies of tube wall, reduces permeability, and can be used for preventing polrvinyl chloride body 1 and rupture because of extraneous extruding.
Wherein, I shape elastic component includes the first cross bar of level and the second cross bar and vertical montant, and montant is vertically placed, and the first cross bar and the second cross bar are horizontally disposed with, and are placed in the two ends of montant.In the present embodiment, I shape elastic component is made into integration, and the length of the first cross bar is more than the length of the second cross bar.Make it addition, it can be rubber, it is also possible to be that other elastomeric materials are made.By arranging I shape elastic component at the projection 3 in cavity, improve anti-pressure ability further.
This utility model uses said structure, its cross-section structure is followed successively by reinforcement 2, cavity, I shape elastic component, double-deck polrvinyl chloride body 1, so whenever having pressure, the outer layer of reinforcement 2 is first subjected to pressure and is alleviated, stopped by the first cross bar of I shape elastic component in cavity and the carrying out of the second cross bar the most again, significantly decompose pressure, the pressure being eventually transferred on polrvinyl chloride body 1 is the least, not only increase the impact flexibility of reinforcement, also effectively prevent polrvinyl chloride body and rupture because of extraneous extruding.
Although specifically showing in conjunction with preferred embodiment and describing this utility model; but those skilled in the art should be understood that; in the spirit and scope of the present utility model limited without departing from appended claims; this utility model can be made a variety of changes in the form and details, be protection domain of the present utility model.
