Cast-in-place by highway movable scaffolding system is often adopted when it is difficult to set up precast bridge site due to terrain or other conditions or it is uneconomical to adopt precast erection scheme from investment considerations.
The highway movable scaffolding system uses pier or pile cap as the supporting base. After the template is installed, assemble steel bars and pour concrete on site. Tension the prestressed steel bars to form the box girder. Then, the equipment moves to the next span for construction. This bridge construction method dates back to the 1950s in Europe. It is now widely used in bridge construction in China.
