The invention relates to a movable energy dissipation assembly for civil engineering. A central fixing sleeve is of a cylindrical tubular structure, a support which is of an integrated structure withthe central fixing sleeve is fixedly installed at the bottom of the central fixing sleeve, eight shock pad sets are fixedly installed in the circumferential direction of the inner wall of the centralfixing sleeve at equal intervals, an energy dissipation liquid containing cavity is formed in the pipe wall of the central fixing sleeve, energy dissipation liquid is contained in the energy dissipation liquid containing cavity, an energy dissipation connecting rod installation hole communicating with the energy dissipation liquid containing cavity is formed in the portion, between every two adjacent shock pad sets, of the inner wall of the central fixing sleeve, an energy dissipation connecting rod is installed in each energy dissipation connecting rod installation hole, one end of each energy dissipation connecting rod is connected with an energy dissipation arc piece installed in the energy dissipation liquid containing cavity, the other end of each energy dissipation connecting rod isconnected with a central supporting column installed in the center of the inner side of the central fixing sleeve, and the outer wall of the central supporting column is connected with the outer sideface of the corresponding shock pad set. According to the movable energy dissipation assembly for civil engineering, energy consumption can be effectively absorbed, and accidents are reduced and avoided.
