Abstract
The utility model provides an anti-freezing plastic composite corrugated pipe comprising an outer pipe and a plastic corrugated pipe body. A cavity is formed between the inner wall of the outer pipe and the outer wall of the plastic corrugated pipe body. The cavity is filled with granular foamed plastic. An insulating layer is provided for preventing frost crack of the drainage pipe.
Description
Technical field
The utility model belongs to discharge pipe line field, especially relates to a kind of plastic draining pipeline.
Background technique
In existing technology, discharge pipe line is under low temperature environment, exist discharge pipe line to freeze, cause resident living draining to be obstructed, affect resident's normal life, for fear of this situation, occur, conventionally in the time of laying water lines, adopt the method for buried waste pipe, not frozen under low temperature environment to guarantee waste pipe, the installation of this method water-feeding & drainaging pipeline brings difficulty, causes the technical problems such as installation cost raising and installation efficiency are low.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of antifreeze plastics compound bellows, is especially applicable to discharge pipe line field.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise outer tube and plastic film capicitor, between the inwall of this outer tube and the outer wall of plastic film capicitor, form cavity, filler particles shape foamed plastics in this cavity.
As further preferred, described outer tube is made by plastic cement or metallic material.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, between the inwall of outer tube and the outer wall of plastic film capicitor, form cavity, in this cavity, filler particles shape foamed plastics not only can play the effect of insulation, and there is gap between granular foamed plastics, because changing outer tube or plastic film capicitor, ambient temperature produces while expanding with heat and contract with cold, can play the effect of buffering, avoid discharge pipe line to break.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
In figure:
1, outer tube 2, granular foamed plastics 3, plastic film capicitor
4, cavity
Embodiment
As shown in Figure 1, the utility model comprises outer tube 1 and plastic film capicitor 3, between the inwall of this outer tube 1 and the outer wall of plastic film capicitor 3, forms cavity 4, the interior filler particles shape of this cavity 4 foamed plastics 2, and described outer tube is made by plastic cement or metallic material.
Owing to adopting technique scheme, between the outer wall of the inwall of outer tube 1 and plastic film capicitor 3, form cavity 4, the interior filler particles shape of this cavity 4 foamed plastics 2 not only can play the effect of insulation, and there is gap between granular foamed plastics 2, because changing outer tube 1 or plastic film capicitor 3, ambient temperature produces while expanding with heat and contract with cold, can play the effect of buffering, avoid discharge pipe line to produce and broken.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
