Abstract

The invention discloses a concrete pavement defect rapid repairing method. The method comprises steps of site cleaning, polishing, impurity removal, repairing material preparation and filling, compaction and leveling, a mixing preparation device is adopted in repairing material preparation, the mixing preparation device comprises a bottom barrel, a rotating shaft is rotatably arranged in the bottom barrel, a first stirring rod arranged in the bottom barrel is arranged on the rotating shaft, a plurality of stirring boxes are arranged on the rotating shaft in a sleeving manner, a plurality of second stirring rods in one-to-one correspondence with the stirring boxes are detachably arranged on the rotating shaft, the second stirring rods are arranged in the corresponding stirring boxes, blanking openings are formed in the lower ends of the stirring boxes, and plugging pieces are arranged at the blanking openings. Compared with the prior art, the method is advantaged in that all layers of materials can be premixed through the first stirring rod and the multiple second stirring rods, the full mixing degree of all layers of raw materials can be guaranteed after the raw materials are mixed layer by layer, the multiple raw materials can be mixed synchronously, and preparation efficiency and quality in the preparation process are effectively guaranteed.

Description

technical field [0001] The invention relates to the field of road maintenance, in particular to a method for quickly repairing concrete road surface defects. Background technique [0002] Concrete pavement defects mainly include concrete panel cracks, pavement potholes, concrete fragmentation on both sides of expansion joints, etc. After the cracks in the pavement concrete are not repaired in time, the cracks will quickly extend until the panel breaks. During the driving process of the vehicle, not only it is easy to cause damage to the wheels of the vehicle body passing by at a high speed, but also there is a greater safety hazard. [0003] The Chinese patent with the application number CN201810592964.8 in the related technology proposes a method for quick repair of concrete pavement defects. Water, inject epoxy grout into the crack, cover the strip plastic cloth on the upper part of the groove filled with grout, drill oblique holes on one side of the crack along the lengt...
