Description
Technical field
The utility model is related to a kind of Bellows Technology fields, and in particular to a kind of high-strength PVC double-wall corrugated pipe.
Background technology
Tubing is widely used in the engineerings such as municipal administration, building, electrical telecommunication, railway, highway, industry, agricultural, road, mineral products,
For draining, sewage ventilation pipe, the protection pipe of various power cables, but common weak yielding, the perishable, Yi Jie of tubing resistance to compression
Dirt blocks, and service life is short, and existing Double-wall PVC bellows anti-pressure ability is poor, for the adverse circumstances of buried underground, often
Phenomena such as fracture distress occur occurs, and how to improve existing Double-wall PVC bellows intensity is the problem that we are faced now,
The utility model is ad hoc in view of the above problems thus counts a kind of high-strength PVC double-wall corrugated pipe.
Invention content
To overcome above-mentioned deficiency, the utility model to provide a kind of high-strength PVC double-wall corrugated pipe.
Technical solution adopted by the utility model to solve its technical problems is：It is characterized in that：A kind of high-strength PVC is double
Wall bellows, including double-wall corrugated tube body, inner wall, outer wall, inside and outside wall sealing plate, inside and outside wall opening, supporting rack, feature exist
In：The double-wall corrugated tube body is equipped with inner wall, outer wall, inside and outside wall sealing plate, inside and outside wall opening, supporting rack, wherein double
One end end of wall ripple tube body is equipped with inside and outside wall sealing plate, and other end end is equipped with inside and outside wall opening, and inner wall is set to double
On the inner hub location of wall ripple tube body, the periphery of inner wall is equipped with outer wall, and supporting rack is set in inner wall and inner wall and outer
In cavity between wall.
The inner wall is smooth wall；The outer wall is bellows wall.
The double-wall corrugated pipe is by clinkering extrusion forming of the ripple outer wall squeezed out simultaneously and one layer of smooth inner wall.Institute
The supporting rack stated by a cylindrical support pipe and ripple supporting framework at, cylindrical support pipe is embedded in ripple supporting rack,
It simultaneously supports the cylindrical support pipe of frame one end and ripple supporting rack is interconnected to form a cover board, cover board and double-wall corrugated pipe
Inside and outside wall opening on ontology matches, and cylindrical support pipe and the ripple supporting rack of the other end are separate type, cylindrical support
Groove is formed between pipe and ripple supporting rack.
The inner wall is embedded in the groove between the cylindrical support pipe on supporting rack and ripple supporting rack.
The supporting rack is to be flexibly connected with the inner and outer wall on double-wall corrugated tube body.
The double-wall corrugated pipe primary raw material is hard polyvinyl chloride.
By using using hard polyvinyl chloride as primary raw material, Double-wall PVC bellows is squeezed by inside and outside the utility model respectively
Go out, one-pass molding, interior walls be smooth, the trapezoidal corrugated of outer wall, by the hollow plastic pipe of double wall between inside and outside wall, passes through support
Frame supports inside and outside wall, unique structure to have intensity high, and inner wall smooth, frictional resistance is small, and circulation is big, and anti-settling ability is strong, resistance to
The advantages that corrosion, service life is long, great promotion and application are commercially available in tubing.
