Description
Technical field
The utility model relates to a kind of riffled tube, the plastic construction wall pipe that particularly a kind of buried pollution discharge is used, employing complex method is made.
Background technique
Riffled tube refers to inner wall smooth, outer wall is with the special construction tubing of radial reinforced rib, because radial reinforced rib adopts i-beam structure, more traditional straight wall pipe compares that to have quality light, intensity advantages of higher, reaching the more straight wall pipe of riffled tube that same intensity requires can material-saving 40-60%, and its superior usability and good cost performance, make riffled tube be widely used in city-building draining, drainage project.
PVC-U riffled tube is made up of herd polyvinyl chloride material, herd polyvinyl chloride material is a kind of brittle material, when making PVC-U reinforcement tubing be subject to active force, easily there is cracking destruction phenomenon, especially outstanding radial reinforced rib, in construction and handling process, very easily by external force collision, cause damage.Meanwhile, the compromise face of riffled tube, make tubing transport and and work progress, be not easy to carrying and drag.
Therefore, a kind of riffled tube of special needs, to solve above-mentioned existing Problems existing.
Model utility content
The purpose of this utility model is to provide a kind of riffled tube, with solve the PVC-U riffled tube that exists in prior art stressed, carry flimsy problem.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of riffled tube, it is characterized in that, it comprises a PVC-U pipe, described PVC-U tube wall is provided with integrated radial reinforced rib with it, described radial reinforced rib top is connected with a polyolefin external layer, defines an inner chamber between described polyolefin external layer, radial reinforced rib, PVC-U tube wall.
In an embodiment of the present utility model, described polyolefin external layer is connected with radial reinforced rib top by extruding coated mode.
In an embodiment of the present utility model, described polyolefin external layer is circular pipe, and described PVC-U pipe is through circular pipe, and radial reinforced rib is connected with circular internal surface of bloom.
In an embodiment of the present utility model, described polyolefin external layer is sheet material base, and is coated on outside PVC-U pipe by rotation.
In an embodiment of the present utility model, the smooth outer surface of described polyolefin external layer.
A kind of riffled tube of the present utility model, compared with present product, PVC-U riffled tube has light weight, intensity is high, abundant raw material source, the advantage that cost is low, coated polyolefine material is flexible material, there is very high toughness and resistance to outer impact strength, it is coated on tubing periphery, effective protection can be formed to tubing, tubing is by external force collision, can not act directly on outstanding radial reinforced rib, but be dispersed in the tube surfaces be made up of polyolefine material, the resistance to external impacts intensity of tubing improves, structure is simple, very practical, realize the purpose of this utility model.
The detailed description and obtaining that feature of the present utility model can consult the graphic and following better mode of execution of this case is well understood to.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of riffled tube of the present utility model;
Fig. 2 is the A portion enlarged diagram of Fig. 1;
Fig. 3 is another schematic diagram of the present utility model;
Fig. 4 is another schematic diagram of the present utility model.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, setting forth the utility model further below in conjunction with specific embodiment.
A kind of riffled tube, it comprises on PVC-U pipe 10, a PVC-U tube wall and is provided with integrated radial reinforced rib 11 with it, and radial reinforced rib top is connected with a polyolefin external layer 20, and defines an inner chamber 30.
As shown in Figure 1, 2, in PVC-U pipe tubing periphery, by extruding coated mode, coated one deck polyolefin external layer.Polyolefin outer skin thickness, requiring different according to application, is 0.5% to 1.5% of pipe diameter.Polyolefin external layer is plastified by extruder to be extruded as material base, under hot melt state, bonds with riffled tube, by thermal shrinkage and the hot-melt bonding performance of polyolefin external layer, is closely fixed on tubing periphery.
Described polyolefin external layer is polyethylene or polypropylene pipe level raw material.
Describedly extrude coated mode, refer to the technological process by heating, plastifying, extrude, make the material base that the plasticizing of polyolefin external layer is molten state, and this material base is evenly coated on the compromise face of reinforcement tubing, the tubing of the smooth circular wall formed for polyolefin external layer with obtained periphery.
As shown in Figure 3, the polyolefin external layer of the round tube billet that the polyolefine material first extruding melting by plasticizing is made, reinforcement tubing passes in round pipe, and pipe is bonded in tubing periphery, moves with tubing, obtains tubing through cooling and shaping; Made tubing, internal layer is PVC-U riffled tube, and periphery is the smooth pipe that polyolefin external layer is made.At the radial reinforced rib top of riffled tube, because polyolefin external layer is in the molten state, be attached to tubing top, its heat some by contact, be delivered to radial reinforced rib top, make it fusing and bond with pipe.On the other hand, polyolefin external layer has certain thermal shrinkage, pipe coated with riffled tube periphery after, after cooling meat, pipe internal diameter is by being greater than riffled tube external diameter, be retracted to and be slightly less than riffled tube external diameter, thus be firmly coated on riffled tube periphery, make the polyolefin external layer of periphery and riffled tube form an entirety.
As shown in Figure 4, the polyolefin external layer of the sheet material base that the polyolefine material first extruding melting by plasticizing is made, reinforcement tubing extrudes direction perpendicular to sheet material base, move to side while rotating, sheet material base presses the mode of spiral, be wrapped in tubing periphery, after cooling and shaping, obtained tubing.
It is high that riffled tube in the utility model remains PVC-U reinforcement tubing intensity, the advantage that cost is low, and it is crisp effectively to overcome this tubing matter, by the problem of external force collision cracky, improves the actual usability of tubing.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; the just principle of the present utility model described in above-described embodiment and specification; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
