There are two the mouth spray settings, is arranged in drilling rod corresponding with the center of upper and lower stirring blade
On, and in approximately the same plane.
A kind of antilock drill bit, application method are as follows: antilock drill bit carries out cement mixing method in cohesive soil and applies
Working hour, entire bit are drilled down into, and are arranged in the stirring blade up and down below drilling rod under soil body drag effect, are stirred up and down
The mouth spray of the circular hole and lower section of mixing blade center is in coincidence status, i.e., the described mouth spray is in opening state in going down process
State is arranged in the stirring blade up and down above drilling rod under soil body drag effect, the circular hole at upper and lower stirring blade center and top
Mouth spray be in 90 ° of positions, i.e., the described mouth spray is in close state in going down process, and lower section mouth spray continues to the soil body
Jet cement slurries, the stirring blade rotates together with drilling rod and carries out cutting stirring to the soil body and cement grout, described anti-
Blade is embraced to remove with drill bit one and get into the soil body, since antilock blade is socketed on drilling rod, under the extruding force of soil, antilock blade
It is not rotated with drilling rod, i.e., with respect to stirring blade, antilock blade remains static, this has effectively blocked twice stirring blade clay
Bonding between particle, preventing blade since clay bonds, the excessive pilling armful brill that generates causes lower brill difficult;Under get into bottom mark
Gao Shi, entire drill bit are lifted up, and are arranged in the stirring blade up and down below drilling rod under soil body reaction force, on
Lower stirring blade reversely rotates 90 °, and the circular hole at center and the mouth spray of lower section are in 90 ° of positions at this time, i.e., the described mouth spray exists
It is in close state in going down process, is arranged in the stirring blade up and down above drilling rod under soil body reaction force, stirred up and down
Blade reversely rotates 90 °, and the circular hole at center and the mouth spray of top are in overlapping positions at this time, i.e., the described mouth spray is drill-through under
In the open state in journey, top mouth spray continues to soil body jet cement slurries, and the stirring blade turns with drilling rod
Dynamic to carry out cutting stirring to the soil body and cement grout, the antilock blade is promoted with drill bit, since antilock blade is socketed in
On drilling rod, under the extruding force of soil, antilock blade is not rotated with drilling rod, i.e., with respect to stirring blade, antilock blade is in static
State, this has effectively blocked the bonding between twice stirring blade clay particle, prevents blade is excessive since clay bonds from generating
Pilling, which is embraced, bores and underground drilling accident is caused to continue to be promoted when rotating whitewashing, until pile is completed.
Compared with prior art, it has the advantage that
1, using antilock blade design, the bonding between twice stirring blade clay particle has effectively been blocked, blade is prevented
Brill phenomenon to be embraced since clay bonds excessive generation pilling, reduces lower brill and promotes resistance, make to stir more evenly, pile is high-efficient,
It is high-quality;
2, when inlaying high-strength plate tooth, pick on stirring blade, it can be carried out and construct into rock, stratum wide adaptation range.
3, using upper and lower whitewashing design, cement slurry utilization rate is high, and stirring is more evenly.
