Abstract
The utility model discloses a PVC -U adds muscle pipe, encircle the polyvinyl chloride pipe body and the strengthening rib of equidistance setting, vacuole formation between the strengthening rib and the polyvinyl chloride pipe body including the polyvinyl chloride pipe body and spiral, and simultaneously, the strengthening rib is hollow structure, the pitch of strengthening rib is 1 -5cm. Hollow structure's strengthening rib and shorter pitch, it is more more heat -resisting than current solid construction.
Description
Technical field
This utility model belongs to tubing technical field, particularly relates to 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, 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；Meanwhile, described reinforcement is hollow structure；The pitch of described reinforcement is 1-5cm.The reinforcement of hollow structure and shorter pitch, than existing solid construction more pressure-and heat-resistance.
Described reinforcement includes that the two ends of the polyethylene layer of outer layer and the steel band of internal layer, polyethylene layer and steel band are fixing and connects, and forms cavity between polyethylene layer and steel band.Preferably, described polyethylene layer and steel band are arcuate structure, and the concave surface of both arcs with convex surface facing consistent.Prior art be steel band is wrapped in polyethylene layer in and form reinforcement, being isolated of this new innovative, and formation cavity, so whenever having pressure, the outer layer of reinforcement is first subjected to pressure and alleviates, and is stopped by the steel band of internal layer the most again, decompose pressure further, the pressure being eventually transferred on polrvinyl chloride body is the least, not only increases the impact flexibility of reinforcement, also effectively prevent polrvinyl chloride body and ruptures because of extraneous extruding.
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, this utility model changes existing solid reinforcement into hollow structure, and reduces the pitch between reinforcement, thus increases voltage endurance capability；
2, reinforcement of the present utility model includes the polyethylene layer of outer layer and the steel band of internal layer, cavity is formed between polyethylene layer and the steel band of internal layer, keep out pressure, effectively prevent polrvinyl chloride body and rupture because of extraneous extruding, and certain heat-insulating property can also be played for the most one layer；
3, this utility model uses the polrvinyl chloride body of hollow structure, still prevents the polrvinyl chloride body at center and ruptures because of extraneous extruding, improves 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 1 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 3；Meanwhile, described reinforcement 2 is hollow structure；The pitch of reinforcement 2 is 1-5cm.This utility model changes existing solid reinforcement 2 into hollow structure, and reduces the pitch between adjacent said rib 2, thus increases voltage endurance capability.
In the present embodiment, reinforcement 2 includes the polyethylene layer 21 of outer layer and the steel band 22 of internal layer, and the two ends of polyethylene layer 21 and steel band 22 are fixing to be connected, and forms cavity 23 between polyethylene layer 21 and steel band 22.In the present embodiment, polyethylene layer 21 and steel band 22 are arcuate structure, and the concave surface of both arcs with convex surface facing consistent.Prior art be steel band is wrapped in polyethylene layer in and form reinforcement; being isolated of this new innovative; and formation cavity; so whenever having pressure; the outer layer of reinforcement is first subjected to pressure and alleviates; stopped by the steel band of internal layer the most again; decompose pressure further; the pressure being eventually transferred on polrvinyl chloride body is the least; so can effectively protect the polrvinyl chloride body at center; such scheme not only increases the impact flexibility of reinforcement, also effectively prevent polrvinyl chloride body and ruptures because of extraneous extruding.
It addition, in order to further enhance toughness, the tube wall of polrvinyl chloride body is a tubular structure (hollow 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.
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.
