The development and application of impact rollers has accelerated the development of geotechnical engineering compaction technology. It provides a new idea to solve the problem of hidden dangers in roadbed quality, such as effectively reducing the post-construction settlement of the roadbed and ensuring the overall stability of the embankment. The roadbed and embankment formed by rolling the roadbed are tested by additional rolling passes to improve the quality of the roadbed. In order to ensure the overall strength and uniformity of the subgrade, the collapsible loess foundation or weak foundation is treated by impact rolling before filling, so that the foundation can meet the requirements of bearing capacity and stability
For old gravel pavements, cement concrete pavements, etc. Road reconstruction using impact rolling technology can speed up the construction progress, meet project quality requirements, etc. At present, except for a few provinces, cities, and autonomous regions in China, most of them have been widely used.

The compaction device and the tractor are connected through a connecting device. The connecting device consists of a traction wrench, a cross joint, a pin, a traction shaft, a flange and a buffer rubber sleeve, which can buffer The impact wheel impacts the tractor and changes its stress state during the towing process, ensuring three degrees of rotational freedom between the tractor and the compaction device. When the tractor drags the compactor wheel to roll forward, the height of the compactor wheel's center of gravity from the ground alternately changes up and down, and the potential energy and kinetic energy generated are concentrated and rolled forward and downward, forming a huge shock wave that continuously passes through the polygonal arc wheel. Impact the ground evenly to make the soil evenly dense.
