Small road roller for sale compaction operation:
- One，The choice of compaction machinery should be light and then heavy. At the beginning, the soil is soft, and if the small road roller for sale is too heavy, it will cause the soil to accumulate, the thickness will be uneven, and the compaction degree will not be guaranteed. Therefore, first use a light small road roller for sale to compact the soil evenly, and then use a heavy road roller to roll to the required degree of compaction after the sugared soil has a certain strength. If it is a vibratory roller, the initial pressure should be static pressure, and then from weak vibration to strong vibration.
- The compaction speed should be slow first and then fast. The rolling speed of the small road roller for sale should be gradually increased with the increase of the number of rolling passes, that is, the rolling speed should be carried out at a lower speed during the initial pressing, which can prolong the action time of the rolling pressure, increase the influence depth, and speed up the soil deformation. , to avoid the phenomenon that the rolling wheel is crowded with soil, and prevent the occurrence of abnormal situations such as the small road roller for sale trapped.
As the number of rolling passes increases, the compactness of the paving layer also increases rapidly. Increasing the rolling speed is beneficial to improve the flatness of the surface of the paving layer and improve the operating efficiency of the small road roller for sale.
