Description
Technical field
The utility model is related to a kind of Country Tubular Goods, are specifically a kind of outer octagon inner circle double-wall corrugated pipe.
Background technology
Circular double-wall corrugated pipe is of the prior art double as its pipeline inside and outside the pipelines generally use such as sewage disposal at present
Wall bellows jointly there are it is following the shortcomings that：1st, because it is circular configuration, tubing is needed to install pipe pillow additional when mounted, allowed it to
It is fixed that (pipe is such as rested the head on, tubing will roll, cause security risk, be not easy when stacking layer by layer withouyt external for square pipe
Installation), it is small that 2, circle corrugated pipe and object contact surface lack stress, and circular tube wall stress is easily deformed when heavier or breakage, due to
Containing a large amount of pollutants and corrosive substance in its sewage, easily pipeline is caused to corrode, pipe-line system is caused to be damaged.
Utility model content
Shortcoming in for the above-mentioned prior art, the utility model are intended to provide a kind of compression strength height, inner wall light
Sliding and corrosion resistant outer octagon inner circle double-wall corrugated pipe.
In order to solve the above technical problems, the outer octagon inner circle double-wall corrugated pipe of the utility model, including outer tube and interior
Layer is managed, and hollow corrugation structure is provided in the outer tube, and the hollow corrugation structure passes through hot-melt welds with the outer tube
Together, pressure release layer is provided between the outer tube and the inner tube, the pressure release layer is tube wall made of compression-resistant material,
The inner tube inner wall smooth.
Preferably, the outer tube is in polygonized structure body.
Preferably, the rounded structure of the inner tube.
Preferably, the thickness of the pressure release layer is 2~4cm.
Preferably, the compression-resistant material in the pressure release layer is general compression-resistant material.
The outer octagon inner circle double-wall corrugated pipe of the utility model has the following advantages：First, its outer tube is arranged to
Polygonized structure substantially increases the ring stiffness of pipeline, further pressure release layer is set in its outer tube lower end, in its pressure release layer
Middle increase compression-resistant material can be very good protection inner tube, ensures that inner tube influences from external force, avoids inner tube because of external force
Caused by damage；Second, internal layer inside pipe wall is arranged to smooth, the flow velocity of sewage can be increased, meanwhile, it will not be because on inner wall
The phenomenon that residue occur and causing line clogging, the small good corrosion resistance of the utility model water resistance, transport easy to install.
Description of the drawings
Fig. 1 is the sectional view of the outer octagon inner circle double-wall corrugated pipe of the utility model；
Fig. 2 is the side view of the outer octagon inner circle double-wall corrugated pipe of the utility model.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe.
As shown in Figs. 1-2, the outer octagon inner circle double-wall corrugated pipe of the utility model, including outer tube 1 and inner tube 2,
Hollow corrugation structure 3 is provided in the outer tube 1, the hollow corrugation structure 3 is existed with the outer tube 1 by hot-melt welds
Together, pressure release layer 4, the pressure release layer 4 pipe made of compression-resistant material are provided between the outer tube 1 and the inner tube 2
Wall, 2 inner wall smooth of inner tube.
Further, the outer tube 1 is in polygonized structure body.So that the utility model connects when in use with other objects
Contacting surface is big, while substantially increases compression strength.
Further, the 2 rounded structure of inner tube.
Further, the thickness of the pressure release layer 4 is 2~4cm.
Further, the compression-resistant material in the pressure release layer 4 is general compression-resistant material.
Specifically, the utility model is since its outer tube 1 is using the setting of outer octagonal _type layout and pressure release layer 4 so that its
Double compression resistant increases its compression strength, meanwhile, the corrosion resistance of the utility model is high, and the application method of the utility model
Very simple, the finished product pipeline produced is directly installed, and can be used after installation is complete, the utility model have with
The advantages of object contact surface is quickly and expediently installed greatly, service life length, compression strength height and corrosion resistance and good.
