Segment assembly Urban viaduct durable Prefabricated Short line bed bridge strength box beam girder mould

- Long line match casting method
- Short line match casting method

There are two types of bridge segment construction: the long-line method and the short-line method. The difference is that the beam segment has different modes of production at the factory. Long-line method prefabricated section, the ength of the bottom mold is equal to the length of the beam, and then each section is casted to obtain several sections. The short-line method is that the bottom mold has only two sections of length, which is taken after pouring one and then poured next for a period until several
segment completed.

Advantages and Benefits

1. Construction Simplicity
• easier installation of external post-tensioned tendons

2. 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.

3. Quality Control Q - A/QC
• precast segment to be produced in factory-manner condition w/ good quality control.
• minimum interruption natural impacts such as bad weather, rain.
• minimum waste of material
• good precision in production

4. Inspection and Maintenance
• external prestressing tendons can be easily inspected and repaired if required.
• maintenance program can be scheduled.
