Hengguang brand bridge prestressed plastic corrugated pipe/preserved hole cast plastic corrugated pipe
Raw material: polyethylene ()
Processing technology: Hot melt extrusion one-time molding
Wave crest - wave distance
Type: Plastic corrugated pipes for prestressed concrete bridges are divided into round pipes and flat pipes
Categories of prestressed plastic corrugated pipes for bridges Code: the round tube is coded as, the flat tube is coded as B.
Inner diameter of pipe: round pipe is represented by the long axis of flat pipe.
Example: Model of a circular plastic corrugated pipe with an inner diameter of
Example: Model of a flat plastic corrugated pipe with an inner diameter of As the main raw material, plastic corrugated pipes for prestressed concrete bridges are formed by hot melt extrusion. The formed corrugated pipe avoids bubbles, cracks, hard lumps and other scratches that may affect use during the production process.
Prestressed concrete plastic corrugated pipes (round pipes, flat pipes) are mainly used to form holes in post-tensioned prestressed concrete structures and components. When the pore-forming material is damaged, the slurry is the last protective barrier for the prestressed steel in the prestressed concrete structure. Plastic corrugated pipe is a new type of hole-forming material. Compared with metal corrugated pipe, it has the following advantages:
. B Plastic corrugated pipe is continuously extruded, has good sealing performance, and is resistant to water seepage and slurry leakage
. The raw material of B plastic corrugated pipe is acid and alkali corrosion resistance, aging resistance, and will never rust
3. The friction coefficient between B plastic corrugated pipe and steel strand is small, only., which can effectively reduce tension. Prestressed friction loss during the pulling process
. B plastic corrugated pipes are not afraid of being stepped on, are not easily chipped by tamping rods, have good flexibility, and have high ring stiffness
. B plastic corrugated pipes are not conductive and can prevent contamination Scattered current corrosion
. B Plastic corrugated pipes have large bends and are easy to connect, which can greatly improve construction efficiency.
