Construction principle of hydraulic tamping machine: The upper hammer head is lifted to the set height through the hydraulic cylinder and then quickly reversely applied force. The upper hammer head is driven by the simultaneous action of gravity and the boosting force of the hydraulic cylinder. Accelerate the fall, and use the conductive backing plate to hit the hammer head to ram the foundation or fill in earth and stone, thereby achieving the purpose of improving the density.
Hydraulic tamping machines play a significant role in eliminating the differential settlement of bridges, culverts and roadbeds caused by differences in construction progress and process conditions of construction teams of different professions, as well as other factors such as deadlines and schedules.
As for the inherent defects and man-made defects of layered rolling roadbed, the hydraulic tamping machine can also eliminate the post-construction settlement that may occur during the use of the foundation in advance, solving the problems of bridgehead jumping, new and old problems that are common in China. The problem of different settlements at the junction of roadbed and roadbed filling and excavation.
Hydraulic compactors can also be used for rapid repair of roads and compaction of backfill materials at the junction of new and old roads, oil depots, ports, airports, urban buildings and other foundations, as well as municipal sanitation waste, and in situations where it is inconvenient or impossible to use. Road sections using large and small construction machinery such as road rollers, impact rollers, and hammer compactors.
