People tend to think that the greater the excitement, the better the compaction effect, which is a misunderstanding. In fact, the real effect on the compaction is the vibration of the vibratory roller on the ground, and the force of this action is two completely different forces from the force of the roller, and there is no relationship between them. It is related to the amplitude, frequency and soil physical and mechanical properties of the roller, with randomness. The excitation force is only related to the parameters of the vibratory roller itself, can be calculated, but can not be detected. In the compaction theory research and testing, the Swedish DYNAPAC company in the world leading level, it is a variety of materials, the internal friction test after the conclusion: the cohesion of small materials in the vibration state of the small internal friction To almost negligible, as long as these materials to meet the requirements of a certain degree of excitement can be completely natural through the vibration; for viscous soil material, the vibration in the state of the internal friction although significantly decreased, but only by vibration also Not enough to make the material dense, must be applied to the necessary static pressure and a large enough to compaction. hobby milling machine for sale uk
