6. A fine tuning support beam for use in adjusting the planar position of a fabricated pavement slab as set forth in claim 1, wherein: and a plurality of groups of support base plates are arranged at the bottom of the support beam.
7. A fine tuning support beam for use in adjusting the planar position of a fabricated pavement slab as set forth in claim 2, wherein: the cross section of the supporting beam is a symmetrical U-shaped plate, and the supporting beam further comprises a plurality of groups of connecting plates for connecting the two U-shaped plates.
8. A fine tuning support beam for use in adjusting the planar position of a fabricated pavement slab as set forth in claim 7, wherein: corresponding threaded holes are formed between the U-shaped plates and the plates, and the U-shaped plates further comprise third bolts, and third nuts are connected with the third bolts through the threaded holes to realize detachable connection of the supporting beams and the vertical adjusting devices.
9. A fine tuning support beam for use in adjusting the planar position of a fabricated pavement slab as set forth in claim 5, wherein: the screw rod seat is of a rectangular block structure, a through hole is formed in the screw rod seat, and the threaded rod freely penetrates through the through hole; a gasket is arranged between the screw rod seat and the nut.
10. A fine tuning method for a fine tuning support beam for adjusting the planar position of an assembled pavement slab, characterized in that a fine tuning support beam for adjusting the planar position of an assembled pavement slab according to claim 2 is adopted, comprising the steps of:
s1: two ends of two supporting beams are placed on the adjacent road panels of the road panels to be regulated in advance, the supporting beams are positioned above the road panels, a threaded rod vertically penetrates through the supporting beams and then is in threaded connection with a hoisting leveling hole in the road panels, and a vertical regulating device penetrates through the threaded rod and then is placed on the supporting beams; then the leveling nut is connected above the threaded rod in a threaded manner, and the leveling nut is screwed until the leveling nut is attached to the upper side of the first leveling assembly; continuously screwing the leveling nut to drive the threaded rod to ascend so as to realize the ascending of the road panel;
s2: after the road surface plate is lifted to a preset height, the threaded rod and the road surface plate connected with the threaded rod are controlled by the first plane adjusting component to move along the direction of the supporting beam until a preset adjusting position is reached;
simultaneously, the second plane adjusting component is used for controlling the first plane adjusting component and the threaded rod to move along the direction perpendicular to the supporting beam;
s3: and then screwing the adjusting nut reversely to enable the threaded rod and the road surface plate connected with the threaded rod to descend until the road surface plate is in alignment with the adjacent road surface plate, and thus the adjustment of the plane position of the road surface plate is completed.
