Excavator Mounted Rapid Impact Compactor

The rapid impact compactor can be directly used with excavators, loaders and other road engineering machinery. As a safe and environmental friendly rapid impact compactor, it is composed of tamper, tamper frame, tamper plate, hydraulic drive device, etc. 

The rapid impact compactor principle is

lift the ram to a certain height with a hydraulic cylinder and release it. The ram accelerates its descent under the combined action of gravity and hydraulic pressure. Fall behind, hit the tamping plate with cushion, put static pressure on the ground, and then tamp the ground through the tamping plate. Since the action of the rammer on the ground is implemented by the ramming plate with cushion and static pressure on the ground, compared with the traditional compaction technology and the continuous action of the mobile high-speed hydraulic rammer, its peak force is small, the action time is long, the function is soft, it is not easy to cut and fill the streamline, and rapid impact compactor has the functions of dust prevention and splash prevention. Compared with the traditional surface rolling technology, its penetration is strong and uniform, it is not easy to form surface hardening in the foundation treatment, and rapid impact compactor can obtain more uniform density in a larger depth range. As a general-purpose mobile high-speed hydraulic compactor, in order to directly tamp the structure without tamping plate, the action mechanism of the ground has greater tamping strength than the traditional tamping technology (dynamic tamping, etc.), and it can also be used to break the ground and other structures.

Application scope of rapid impact compactor

Rapid Impact Compactor can realize the overall compaction of thick fill, improve productivity, and reduce or avoid the interlayer sliding and separation that may be caused by layered compaction technology. After compaction, the thick filler can be uniformly and effectively increased. The Rapid Impact Compactor can also deal with the existing large-scale compaction or compaction machinery, such as the back of the abutment, the side of the culvert, the surrounding of the pier, the slope, the turning area of the compaction machinery to the machinery, the no road area, etc., which cannot approach the foundation of the trend, and solve the common problems such as the early rise damage of the road, the jumping of the abutment, the inclination of the pier, the sliding of the slope and so on after the partial subsidence of the important facilities such as the expressway. Rapid Impact Compactors can also reinforce rivers and dams. At present, it is impossible to solve the problem of slope collapse of high velocity soil infiltration machine for earth dams built and reinforced by layered compaction technology of small and medium-sized compaction machines.

Construction effect of rapid impact compactor

In construction projects, traditional compaction technologies include rolling, vibratory compaction, impact compaction and dynamic compaction. The effective depth of Rapid Impact Compactor can reach 4-10m, which is second only to impact dynamic compaction and larger than all kinds of compaction machinery, including impact roller. Rapid Impact Compactor can be used for large infrastructure and military facilities such as the back of abutment, culvert side, highway, railway subgrade, embankment slope protection, airport, port, etc., especially suitable for narrow construction sites.
