Described waist tooth, back, the maximum gauge of trapezoidal brill wall guard shield and bottom heel teeth of falling are D-20mm, and D is the Pile Foundations Design diameter.
Described three base plate heel teeths are positioned at two of both sides outwardly, in the middle of being positioned at inwardly.
The described trapezoidal steel plate both sides of falling are welded with waist tooth stiffener.
The both sides of described back are welded with the back stiffener.
Described circular platform type bores and has the slurry hole of overflowing on the wall.
Compared with prior art the utlity model has following characteristics and beneficial effect:
The one, the utility model passes through to bore the wall waist at the circular platform type of rotary drilling rig cleaning bottom of hole drilling tool and increases the waist tooth, and increases bottom heel teeth towards the back in the bottom by the precious pretty young woman's bucket tooth that changes bottom edge, can effectively embed hole wall, improves the efficient of cleaning bottom of hole.
The 2nd, increased back and improved the form of boring the wall guard shield by bore the wall waist at the circular platform type of rotary drilling rig cleaning bottom of hole drilling tool, make cleaning bottom of hole after hole wall mud skin can effectively form, accidents such as prevent to collapse hole, undergauge take place.
The 3rd, it is easy to make that the utility model only needs that existing common drilling tool is reequiped field machining.
