s2, chiseling: the equipment is moved to a cutting line, a chiseling bracket (43) is put down through a plurality of chiseling hydraulic supporting rods (48), a chiseling motor (41) is started, the equipment is pushed forward, and the damaged part of the bridge deck is chiseled through a plurality of chiseling sheets (45);

s3, cleaning: cleaning the bridge floor after chiseling:

s4, spreading: putting the stirred repairing material into a hopper (51) through a feed opening (72), pushing and pulling a telescopic cylinder (53) through a plurality of baffles to open a drawing baffle (52), pulling the equipment backwards, and laying the repairing material on a chiseled road base surface through a blanking opening (511);

s5, flattening: before the step S4, a plurality of height-adjustable wheels (23) are adjusted, a road roller (63) falls on a road surface, and when the step S4 is started, a flattening double-shaft motor (61) is started, the newly laid repair material is flattened through the road roller (63), and the newly laid repair material is flattened and tamped through the acting force of the flattening double-shaft motor (61) driving a balancing weight (65) to rotate;

s6, maintenance: and sprinkling water or coating the paved bridge deck according to different repairing materials.
