The impact compaction of an impact roller involves three processes:

• 1. Under the strong impact of external loads, soil particles overcome the frictional resistance between particles to produce sliding and rolling displacement, and move and fill to finer and more stable positions, resulting in the compression of void volume. The reduction of sand and soil gaps leads to a denser roadbed surface;
• 2. Under the strong impact energy, soil particles not only produce sliding and rolling displacement, but also local fragmentation at the edges and corners of large particles, resulting in a decrease in soil volume. Fragmented small materials are more conducive to filling and compacting gaps;
• 3. Under the tremendous impact of the CMG impact roller, the material body undergoes a certain degree of compression deformation. Although this elastic deformation appears weak compared to the first two processes, it is also an effect that other compaction machinery besides dynamic compaction cannot achieve with the CMG impact roller.

The enormous impact force of an impact roller not only brings compaction effect, but also brings great destructive force to sandy and silty soil that is more prone to large displacement. The pressure of the impact roller should be moderate, which is also the reason why the pentagonal impact roller is commonly used for sandy and silty soil.

It is precisely for this reason that the triangular impact roller is not suitable for road surface crushing, as the huge impact force produces a huge recoil force, causing huge damage to the impact roller and tractor.

There are many techniques for impact roller compaction construction. Speaking of this, many spectators can't help but want to call me. My phone number is 185 3836 1111 on WeChat.

Professional, very suitable for use on me in the field of impact rollers.

The impact compaction wheel is an important component of the impact compaction machine, usually composed of 3 to 5 non circular equal edge tugs. It achieves the purpose of compacting the road surface and roadbed through continuous rolling impact technology. Due to the lack of power in the CMG impact compaction wheel itself, it needs to be driven by large traction equipment to work.

The pentagonal impact roller is mainly used for road surface crushing and impact roller compaction construction of silty or sandy soil in certain areas. I'm not sure if you understand.
