Bore dia is 25~40 millimeters, and bar planting hole depth is 600~850 millimeters, and bar planting hole site is to avoid in reinforced concrete structure
Reinforcing bar is to determine principle, goes out bar planting hole drill hole location in reinforced concrete structure surface markers later.
Step 2, bar planting drilling is carried out.
Step 2.1, in the bar planting hole drill hole location on reinforced concrete structure surface, the water drilling puncher of big drill bit, institute are used
The drilling diameter for stating big drill bit is suitable with bar planting bore dia, first light to bore field planting muscle hole location, then bores into reinforced concrete structure
Hole and hydraulic pressure return slag；Big drill bit water drilling puncher pierces in reinforced concrete structure 100~200 millimeters, makes in concrete structure
Bar planting hole with 100~200 millimeters deeps.
Step 2.2, the big drill bit of water drilling puncher is changed to small drill bit, the drilling diameter of the small drill bit is bar planting hole
The 1/2~2/3 of diameter is continued along bar planting hole to reinforced concrete structure internal drilling and hydraulic pressure return slag；Small drill bit water drilling puncher
50~100 millimeters are pierced in reinforced concrete structure, makes that there is bar planting prebored hole in concrete structure.
Step 2.3, the small drill bit of water drilling puncher is changed to big drill bit, along bar planting preboring hole drilling and hydraulic pressure return slag,
Make aperture of the big drill bit water drilling puncher by the borehole enlargement of bar planting prebored hole to bar planting hole；
It is repeated in step 2.2 and step 2.3, until bar planting hole depth reaches the depth of pore forming of design.
In boring procedure, water drilling puncher should keep vertical, slow and uniform drilling operation as far as possible, drill while using
Water drilling puncher progress hydraulic pressure return slag will bore to mince in hole clears out hole.
Step 3, after the pore-forming of bar planting hole, the mud in bar planting hole is washed away completely with clear water, then wiped bar planting hole with staple
Only.
Step 4, after the bar planting hole of step 3 is dried, anchoring adhesive, the note of filling device are fed into bar planting hole using filling device
Jiao Zui is protruded near the bottom hole in bar planting hole, and the gluing nozzle of filling device is extracted on marginal not glue side out, and anchoring adhesive is perfused to apart from bar planting hole
Behind 200~300 millimeters of aperture, stops injecting glue and be fully drawn out the gluing nozzle of filling device.
Step 5, bar planting immediately after the completion of the injecting glue of step 4, bar planting reinforcing bar is slowly inserted into bar planting hole, and edge is inserted on side
Certain orientation slowly rotates, and keeps anchoring adhesive and bar planting rebar surface and bar planting hole inner wall bonding closely knit；The insertion of bar planting reinforcing bar is planted
Guarantee not disturb for 24 hours after the bottom hole of muscle hole, under room temperature, bar planting is completed after 48 hours.
Prioritization scheme does bar planting hole using heating rod after being cleaned bar planting hole with staple in step 3 of the invention
Dry processing.
The present invention has substantive distinguishing features and significant progress following prominent: the present invention is drilled to again using repeatedly change drill bit
Big drill bit is changed to small drill bit, one can effectively avoid the generation of hole inner concrete inner core when drilling to certain depth by hole technology
Fracture, one can be broken will pass through the discharge of hydraulic pressure return slag by the concrete inner core drilled out by big drill bit brill, effectively ensures bar planting hole
Hole quality and pore-forming efficiency, be very suitable to deep pore reinforced drilling construction.
Specific embodiment
Below by embodiment, the invention will be further described.
