Work.
Before this step, the Prefabricated road repairing unit 100 of suitable dimension can be first selected, then to the road portion damaged
It cut, root out road repair hole 210 to obtain matching with the size in position.
S20: the more reinforcing bars 211 for being stretched on its side wall are implanted at road repair hole 210；
Wherein, implantation is concretely first drilled in predeterminated position using electrical drilling machine, then reinforcing bar 211 is installed to hole
It is interior.The predeterminated position is also determined by 12 position of reinforcement installation slot of Prefabricated road repairing unit 100.
S30: the structure slurry of prefabricated thickness is injected in the bottom at road repair hole 210；
Wherein, structure slurry can be concrete grout, it is preferred that structure slurry can be starched for strong concrete.
S40: by the above-mentioned corresponding installation of Prefabricated road repairing unit 100 to road repair hole 210, wherein Mei Yigang
The correspondence of muscle 211 protrudes into each reinforcement installation slot 12；
Wherein, lifting appliance can be used to lift Prefabricated road repairing unit 100, when Prefabricated road is repaired unit
After in 100 corresponding installations to road repair hole 210, the bottom wall 11 of Prefabricated road repairing unit 100 contacts formation with structure slurry
Connection.
S50: injecting structure is starched in the gap between Prefabricated road unit 100 and road repair hole 210；
Wherein, after injecting structure slurry, structure slurry can be inserted to reinforcement installation slot 12 and limiting slot 14, pre- to reinforce
Connection between roadway element 100 processed and road repair hole 210 can determine whether grouting fills by observation grouting observation panel 15
Point, judgment mode concretely, when all grouting observation panels 15 all emerge structure slurries, illustrates that injecting structure slurry is completed.
It can also include step S55 after step S50: use concrete landfill grouting observation panel 15 and hole for hoist 161.
S60: concrete curing processing is carried out.
Wherein, the sides such as watering natural curing, spray-coated film maintenance and plastic film package maintenance can be used in concrete curing
Method.
