    1. Detailed information

    1) pedestal

    According to the design requirements of formwork, the layout of prefabricated pedestal and track layout should be planned and designed. Especially, the transverse spacing of prefabricated pedestal is larger. The transverse spacing of traditional design pedestal is about 5 m. The transverse spacing of self-propelled integral hydraulic formwork pedestal needs to be 6.0 M. In addition, the height of the pedestal should be considered. The height of the traditional formwork pedestal is generally 20-30 cm, but the displacement of the self-propelled integral hydraulic formwork is considered, and the pedestal height is set to 50 cm.

    2) external mode

    A trolley is arranged at the bottom of the exterior mould for the falling and transverse movement of the formwork. The trolley is supported by a jack-up cylinder and a screw. The ground is designed with a pre-embedded track for the trolley to slide out.

    3) Hydraulic system

    The hydraulic system trolley is fixed with the side die, which is divided into transverse hydraulic system and vertical hydraulic system. The vertical movement and transverse adjustment of the whole side die are realized during the installation and removal of the template.

    4) core mold

    A steel plate is set at the bottom of the core mould to prevent the template from sliding out and flooding. The template is divided into left and right parts. After one side is closed, the other side is closed, and the two sides are moved back to the middle to facilitate sliding out.
