When the plate thickness is more than 200mm, a roller with a diameter of 168mm should be used; a roller with a diameter of 219mm can be used for bridge deck paving or roads with a smaller thickness. Considering the flattened mixture, a larger shaft diameter is more advantageous; considering the effective compaction depth, a smaller shaft diameter is more advantageous. The diameter of the shaft is mainly 168mm, 219mm and 240mm. Using a larger shaft diameter has higher construction efficiency and better flatness, but the surface slurry is easier to segregate and the slurry is thinner. Using a smaller shaft diameter has better slurry lifting effect, but the shaft is easy to deform, so attention should be paid to correction. Generally, the axle length should be 600~1200mm longer than the road width.

The rotational speed of the vibrating shaft of the three-roller paving leveler should not be greater than 380r/min. The rotational speed of the vibrating shaft has two types: 300r/min and 380r/min. Generally, a smaller speed should be used to ensure effective tapping and slurry lifting. . The vibration power should be greater than 7.5kW; the maximum driving speed of the drive shaft should not be greater than 13.5m/min, and the drive power should not be less than 6kW. Ensure that the vibrating shaft and the drive shaft have enough power to overcome the resistance of the mixture and the template, and realize the functions of paving, vibrating compaction and leveling. The three-roller leveling machine essentially belongs to the transformation form of small machines. It combines the vibrating beams and rollers during the construction of small machines and installs them on the equipment with driving force shafts. Therefore, in the construction of high-grade roads, the three-roller leveling machine alone cannot guarantee the vibration and compactness of the pavement concrete in the lower part of the panel. It must be equipped with a dense row of vibrators for construction.

　　 Vibrator and Vibration

When paving concrete panels with a three-roller unit, it must be equipped with a row-type vibrator equipped with a plug-in vibrator group. The vibrator has a form of installing only one row of vibrators, or it is equipped with auxiliary paving at the same time. The form of auger and pine side control scraper. Generally, a row-type vibrating rod-inserting vibrating vibrator equipped with a spiral distributor and a loose side control scraper should be used, and it has an automatic walking function.

The inserting vibrating type vibrator is suitable for thicker roads. The built-in motor inserting type vibrator can be used. The vibration frequency can be selected between 50~200Hz. When the panel thickness is large and the slump is low, it can be used. Use a high frequency vibrating rod above 100 Hz. The vibrating rod is divided into models by the diameter of the rod. The diameter of the vibrating rod is generally 50-100 ram, and the effective radius is generally 4 to 10 times the diameter of the vibrating rod. The larger the diameter, the larger the effective radius, and the greater the slump of the concrete, the greater the effective radius. The spacing should not be greater than 1.5 times the effective radius of action, and not greater than 500mm.

　　 When the pavement thickness of the bridge deck is less than 150mm, the vibrating beam can be used. The vibrating frequency can be 50~100Hz, and the vibrating acceleration can be 4~5g (g is the acceleration due to gravity).
