Description
Technical field
The present invention relates to concrete dabbing, more particularly to a kind of self-propelled concrete dabbing machine and its dabbing method, belong to
Concrete construction technical field.
Background technology
In field of civil engineering, reinforcing bar and concrete are to use most commonly used construction material in the world at present, largely
Building structure is all built up by armored concrete, but erosion due to concrete carbonization and chloride etc., causes reinforcing bar
Corrosion.Reinforcing bar volumetric expansion, which produces larger splitting stresses, after corrosion makes concrete cracking, so as to influence the security of structure and resistance to
Long property.To solve the above problems, the recovery project measure commonly used in engineering is to remove old concrete and pour new coagulation
Soil.
The adhesive property of New-old concrete is the key for being related to concrete repair engineering success or failure.New-to-old concrete interface
Bond effect quality is influenced by factors, the species of degree of roughness, interfacial agents, the intensity of New-old concrete and benefit such as interface
Force orientation of liquid/solid interface etc., wherein, the adhesive property of new-to-old concrete interface, depend greatly on interface processing and
Interface roughness, therefore coarse processing is carried out to new-to-old concrete interface, and be to the rational evaluation of the degree of roughness after processing
Important sport technique segment in concrete reinforcement reinforcing engineering.
Dabbing technique is one of main technique of the coarse processing of new-to-old concrete interface, the quality of dabbing effect, direct shadow
The bond quality of New-old concrete is rung, so as to influence the service life of structure.Traditional artificial chiseling, bristle and mechanical carving groove work
In addition to efficiency is low, subject matter is thoroughly remove laitance skill；Though milling technique can solve the problems, such as laitance, easily cause mixed
Coagulate native surface loose damage and form the different groove of a lot of depth and be unfavorable for surface cleaning；Its shot feather plucking of shot-blasting machine technique
When impact it is less big, the surface evenness that worked after construction is preferable, but dabbing depth as shallow, concavo-convex pitted skin unobvious, New-old concrete
Between cohere not good enough, the shot recovery of feather plucking is difficult in addition, and road surface shot-blasting machine is expensive；Though and plucking efficiency of constructing
It is high but a weak floor can be formed in concrete surface.
For disadvantages mentioned above, Chinese invention patent CN201310152724.3 discloses a kind of impact type pavement roughening machine.
A kind of impact type pavement roughening machine includes frame and rack-mounted wheel, on the chassis of the frame and along frame width
Direction is rotatably connected to roller bearing one and roller bearing two, is provided with the roller bearing one and along its length multiple thin bars one, multiple

The impact ball on hair road surface, it is provided with the frame for driving drive device that roller bearing one and roller bearing two rotate and for will
The power of the drive device output transmits the transmission device to roller bearing one and roller bearing two.Though the patent of invention can improve feather plucking work
Make efficiency, road surface feather plucking quality is high, but the device of the invention may be only available for the feather plucking work of pavement structure or structure top surface
Make, the feather plucking work of texture edge, inclined-plane, bottom surface can not be applied to；The device of the invention can only realize beating for some direction
Hair work, the hair side for ultimately forming teeth groove type are unfavorable for the lateral bond effect of new-to-old concrete interface；The device of the invention is not
The degree of roughness of hair side is detected, not coarse enough the local area of feather plucking can not be detected, and leave potential safety hazard.
In order to improve above-mentioned deficiency, Chinese invention patent CN201510813489.9 discloses a kind of machine-carried type dabbing machine,
The dabbing for including rail body for setting or being detachably arranged in lift support meanss including lift support meanss, activity
Machine track and the dabbing owner's body being fixed on rail body.The device still needs to be connected by support meanss with ground, when
Unhairing machine needs Mobile support device to start the feather plucking work of next stage when being moved to track end, needed in addition before feather plucking
Wanting the angle of adjusting apparatus makes it parallel with the plane of pre- feather plucking, adds the complexity of personnel's manipulation.
In summary, gratifying full-automatic roughening device is there is no in the prior art.
