Performance analysis
Plastic corrugated pipes are used in post-tensioned prestressed concrete structures as hole-forming pipes for prestressed tendons. Plastic corrugated pipes are generally It has the following properties:
It can improve the anti-corrosion ability and improve the protection of prestressed tendons. Metal corrugated pipes do not have permanent anti-corrosion capabilities, but corrugated pipes produced from high-density polyethylene or polypropylene can provide long-term anti-corrosion protection for prestressed tendons.
The friction coefficient of plastic bellows is smaller than that of metal bellows. A small friction coefficient can mean small prestressing loss or higher effective stress, which is particularly beneficial for ultra-long prestressed tendons and ring structures, and therefore it is possible to reduce the amount of prestressed tendons to reduce costs.
It has the characteristics of high strength and rigidity, not easy to deform, not easy to be flattened, not easy to rust, and has a long storage time.
It has good construction performance, provides convenience for installation and fixation, and is not easily broken by the vibrating rod, making the joints firm.
Good sealing can create conditions for using vacuum-assisted grouting.
