S4. After the concrete is quantitatively fed, the controller (3) automatically controls the leveling motor (609) to work. The leveling motor (609) drives the first spiral leveling roller (603) to rotate through the leveling reducer (608). The first spiral leveling roller (603) drives the drive gear (606) to rotate. The drive gear (606) drives the transmission gear (605) to rotate. The transmission gear (605) drives the driven gear (607) to rotate. The driven gear (607) drives the second spiral leveling roller (604) to rotate. The first spiral leveling roller (603) and the second spiral leveling roller (604) rotate simultaneously to level the concrete fed through the feeding hopper (501). The leveling frame (1) is driven by the tractor and the tractor frame (2) to move, which drives the scraper plate (611) to move and scrape the concrete road surface after it has been leveled by the first spiral leveling roller (603) and the second spiral leveling roller (604). S5. After being scraped flat by the scraper plate (611), the concrete passes under the vibrating mechanism and is vibrated and compacted by multiple vibrating rods (704) installed on the vibrating frame (703). When the vibrating rods (704) are working, the controller (3) controls the dual output shaft motor (707) to work. The two output shafts of the dual output shaft motor (707) drive the drive shaft (708) to rotate through the coupling. The drive shaft (708) drives the vibrating cam (710) to rotate. The vibrating cam (710) drives the drive seat (712) to move, which drives the cam shaft (716) to move up and down on the inner wall of the stop stroke groove (715). This drives the fixed bushing (717), the vibrating frame (703) and the vibrating rods (704) to move up and down, thus compacting the concrete. S6. After the concrete pavement is compacted by the vibrating mechanism, the smoothing motor (804) is automatically controlled by the controller (3). The output shaft of the smoothing motor (804) drives the drive gear (805) to rotate. The drive gear (805) drives the driven gear ring (807) to rotate, which in turn drives the smoothing roller (803) to rotate, thus smoothing the concrete pavement. S7. During the concrete pavement pouring construction, the concrete data in the pouring is recorded and stored through the data storage module (814), and then fed back to the controller (3) and the calculation module (815) to calculate and monitor the concrete density and feed the data back to the controller (3). When the density is not up to standard, the controller (3) automatically controls the three-color sound and light alarm (813) to sound an alarm.
