Impact compactor is an engineering compaction equipment based on the action of impact energy. Its core converts kinetic energy into concentrated impact force on the ground through the periodic fall (or rolling impact) of heavy-duty impact wheels, achieving deep compaction treatment of materials such as soil, crushed stone subgrade, and fill. It is often used for foundation reinforcement and site leveling of large-scale infrastructure such as highways, railways, airport runways, and DAMS, and can effectively improve the bearing capacity of the foundation and reduce settlement in the later stage.
