Abstract

A roadbed powerful rammer compactor resolves the technical problems that a road roller in the prior art is poor in roadbed-stabilizing effect, labor-consuming, time-consuming, and low in efficiency. The roadbed powerful rammer compactor structurally comprises a vibratory hammer mechanism provided with a vibratory hammer, a drive motor and a vibration exciter, wherein the bottom end of the vibratory hammer is additionally provided with an action base board, and convex strips are evenly distributed on the bottom surface of the action base board. The structures of the convex strips include two types. One is a side-pressure broken board which is arranged on the bottom surface edge of the base board, and an action surface of the side-pressure broken board is a concave arc-shaped surface. The other is even-pressure convex strips which are evenly distributed in the middle of the bottom surface of the action base board, an action surface of each even-pressure convex strip is a convex arc-shaped surface, and the side-pressure broken board cuts off an outer side pressure produced by the vibratory hammer on a soil body. Acting force of the vibratory hammer mechanism is evenly scattered through the even-pressure convex strips in the middle of the bottom of the action base board, side pressure produced by the vibratory hammer mechanism on the soil body is cut off through the side-pressure broken board at the edge of the base board, and therefore overlarge side pressure on the edge of a bridge is avoided, and a bridge body is prevented from being damaged.
