Adjustment and control drilling rod perpendicularity；Mud off is supplemented in drilling, rig operating, the bit insertion soil body, mud presses Fig. 1
Middle arrow route does circulation temperature lowering, protects cutter head, enters into pipe from mud, reaches slurry pipeline, and rotation is reached from top to bottom
Bucket is dug, and is flowed out from rotary digging bucket cutter head, in access aperture, by mud circulating pump, make mud circulating cooling cutter head, mud
Overall circulation, cooling effect and its substantially；Rubble and silt are pulled out after rotary digging drill bit destruction firm hard formation, is drilled into design hole
Deep, after the completion of work, rotary drilling rig extracts drilling rod and shifts next hole position.
A kind of method for entering rock technique using direct circulation rotary digging of the invention, comprises the following steps：
Step 1) smooth location, accomplish " three supplies and one leveling "；
Step 2) pile foundation positioning, according to Pile Foundations Design plan, stake position setting-out, measurement and positioning；
Step 3) casing should be accurately buried in the stake position for determining before drilling, and ensure that casing bottom is sitting in strongly weathered sand-rock
On.Accurate fixed bore position, isolates the surface water, and stabilization aperture is native and protects hole wall not collapse, and is carried out with sharp boring work；
Step 4) it is that rotary drilling rig prepares drilling mud to ensure hole quality；
Step 5) rig is in place, by drill bit align piles position, check it is errorless after adjustment rig perpendicularity, in drilling process, adopt
Instrument is carried with equipment observe inspection, adjustment and control drilling rod perpendicularity at any time；Mud off is supplemented in drilling；
Step 6) rig operating, the bit insertion soil body, to mud into pipe input mud；
Step 7) mud flows to rotary digging bucket cutter head by arrow head part in figure；
Step 8) mud integrally circulates, and reaches the purpose of cooling；
Step 9) rotary digging drill bit destruction firm hard formation after rubble and silt are pulled out, be drilled into design hole depth；
Step 10) the rotary drilling rig extraction drilling rod next hole position of displacement.
The present invention is suitable for different places, has a wide range of application, and saves human cost, increases economic efficiency and construction quality.
Specifically have the beneficial effect that：
