• Construction Simplicity. Easier installation of external post-tensioned tendons.
• Time Savings/Cost Effectiveness. precast segment to be prefabricated and stored at casting yard while foundation and sub-structure are being built.
• By using efficient erection method and equipment, the rapid installation of viaduct can be achieved.
• Quality Control Q-A/QC
• Precast segment to be produced in factory-manner condition good quality control.Minimum interruption natural impacts such as bad weather,rain.Minimum waste of material. • Good precision in production.
• Inspection and Maintenance,external prestressing tendons can be easily inspected and repaired if required. Maintenance program can be scheduled.
• Retractile,easy-demoulding,Simple operation,saves a lot of labor,greatly improves the construction efficiency,shortens the construction period
