This utility model discloses a movable energy-saving support frame for large-load cast-in-place box culverts, relating to the field of highway construction technology. Specifically, it is a movable energy-saving support frame for large-load cast-in-place box culverts, comprising multiple support columns, with multiple brackets welded between the support columns. Support plates are welded to the inner walls of two of the brackets. An electric push rod is fixedly installed on the upper surface of the support plate via A-bolts, and a connecting plate is fixedly connected to the output end of the electric push rod. In use, this equipment can support the formwork used during box
culvert casting from three directions, with rapid operation and significant results. It ensures strength, rigidity, and stability during
casting and movement. Furthermore, the equipment meets the static and dynamic load requirements, and the assembled frame and components meet the goal of movable construction. It optimizes the
assembly and disassembly process, solving the problem of repetitive installation and dismantling of supports during cast-in-place box
culvert construction and reducing manual labor.
