Description

A kind of antilock drill bit and its application method
Technical field
The present invention relates to the mechanical related more particularly to a kind of antilock drill bits of underground construction.
Background technique
Cement mixing method uses more and more wider, soil cement as water-stop curtain and foundation stabilization in underground foundation at present Mixing pile construction generally uses single shaft, and two axis, three axis and multi-shaft stirring stake machine are constructed, when constructing in the sticky soil body, by Cohesive force is strong between clay particle, is not easy to stir evenly, and usually occurs drill bit pilling armful in whipping process and bores, grout phenomenon, Cause brill resistance under drill bit big, brill or extraction can not be descended by seriously embracing drill bit when boring, and be stirred unevenly, pile body pile low efficiency, matter It is poor to measure, and causes huge loss to construction;A kind of antilock drill bit and its application method can effectively solve the difficulty encountered above.
Summary of the invention
It is an object of the present invention to provide a kind of antilock drill bit and its application methods.The present invention be exactly to solve the above-mentioned problems, Antilock drill bit is mainly used for cement-soil stirring pile construction, and antilock blade design has effectively blocked first of stirring blade and second Bonding between road stirring blade clay particle prevents blade is excessive since clay bonds from generating pilling armful brill phenomenon, under reduction Resistance is bored and promoted, makes stirring more evenly, pile is high-efficient, high-quality.
The present invention is realized by following technical approach:
The present invention relates to a kind of antilock drill bit and its application method, the antilock drill bit includes six square joints, drilling rod, stirring Blade, reinforcing rib, wear-resisting tile, antilock blade, whitewashing conversion section, upper and lower stirring blade, pick, drill bit, mouth spray are described Six square joints are welded on drilling rod top, and the stirring blade right-angled intersection is alternate to be arranged on drilling rod, and the wear-resisting tile is inlayed On drilling rod, the antilock blade is connect by wear-resisting tile bolt with drilling rod, and the pick is mounted on first of drilling rod and stirs It mixes on blade.
The drill bit expanded diameter is 400~2000mm.
The antilock blade has twice, is arranged in up and down between stirring blade and stirring blade, the antilock blade It is made of two panels Ω type blade, and by bolt fastening, is socketed on wear-resisting tile.
There is a circular hole at the center of stirring blade up and down, and upper and lower stirring blade is socketed in drilling rod by whitewashing conversion section On, upper and lower stirring blade is freely rotatable, and rotation angle is 0~90 °.
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.
