- Installation: First, lay the track, move the pedestal system, and install the walking device. Then, lift the bound steel keel into the pedestal, install the end formwork to fix the steel keel, and install the tie - rods to complete the formwork installation.
- Concreting: After the formwork is installed, pour the concrete into the formwork and vibrate it with a vibrator.
- Demoulding: After the concrete reaches the demoulding strength, remove the tie - rods at the top, start the hydraulic device to complete the demoulding, and then move the poured T - girder to the curing room for curing by using the movable pedestal.
