This  precast segment casting form system consists of fixed vertical bulkhead of the cross section shape at one(long-line method)/both ends(short-line method), side forms, core forms with movable supporting system, and soffit with trolley.

• The side forms are fixed on the bracket system with spiral adjustment rod and rotating hinge, and the template can be adjusted through the spiral adjustment rod

• Two sets of soffit and supporting systems are equipped for one cast cell(for the matching and will be casted segments respectively). Their position are exchangable: apply the trolley for moving our, and crane for moving in. It is equipped with two sets of hydraulic jack horizontally and vertically respectively in order to achieve the 3D movement of the soffit and the matching segments.

• The core form is designed to assemble smaller units to achieve the cell dimension change, which can be adjusted according to each precast segment. The core form is fixed to the sliding beam. The hydraulic system realizes its vertical extension /collapse and horizontal opening/closing.

• The supporting frame of the side form is designed with sufficient stiffness and strength to avoid both the side shifting and deformation of the formwork during the casting process.

• The convertibility of the precast segment in length, cross-section, and curvature can be realized.

Auto position adjustment:  The accuracy for 3D position adjustment is +-1mm, takes no more than 1 hour.
