Abstract
The invention discloses a kind of abrasion drill drill bit device processing uneven geology, belong to pile foundation construction technical field.It comprises convolution drill bit, it is characterized in that: the outer cover of described convolution drill bit is equipped with steel bushing (2), the cylindrical of the drill bit leg (1) of described convolution drill bit is fixedly connected with the upper end inside wall of steel bushing (2), and the lower end surface of described steel bushing (2) is provided with several carbide button heads (3) along its even circumferential.Structure of the present invention is simple, can creep into by smooth vertical, ensures hole quality, ensure the quality of pile foundation when effectively can ensure that drill bit runs into uneven geological condition.Simple structure of the present invention, principle be understandable, draw materials conveniently, with low cost, there is higher practicality.
Description
Technical field
The present invention relates to a kind of abrasion drill drill bit device, specifically a kind of a kind of abrasion drill drill bit device when adopting abrasion drill to carry out pile foundation construction under uneven geological condition, belongs to pile foundation construction technical field.
Background technology
Current most of bridge foundation adopts pile foundation, and pile foundation is the bored pile adopting convolution drilling machine construction then more.Drilled pile is in work progress, because geological condition can not be all desired uniformity soil layer, and when running into uneven geological condition during existing abrasion drill construction, in drilling process, easily cause drill bit to comparatively weak soil matter side deflection, cause pore-forming deflection, reinforcing cage to divide into the situations such as installation, directly affect the quality of pile foundation.
Summary of the invention
For the above-mentioned defect existed in prior art, the invention provides a kind of abrasion drill drill bit device that can be used in processing uneven geology, utilize it to hole, can ensure that when running into uneven geological condition drill bit smooth vertical creeps into, ensure hole quality.
The present invention is achieved by the following technical solution: a kind of abrasion drill drill bit device processing uneven geology, comprise convolution drill bit, it is characterized in that: the outer cover of described convolution drill bit is equipped with steel bushing, the cylindrical of the drill bit leg of described convolution drill bit is fixedly connected with the upper end inside wall of steel bushing, and the lower end surface of described steel bushing is provided with several carbide button heads along its even circumferential.
The present invention utilizes equally distributed high-strength alloy tooth head on steel bushing lower end surface to carry out mill to uneven geology to cut, and the soil body is fixed in sleeve by recycling steel bushing, then utilizes drill bit cutting soil to carry out drilling construction.Acting as of steel bushing: can creep into by smooth vertical when can ensure that drill bit runs into uneven geological condition, can hole quality be ensured.Convolution drill bit in the present invention can adopt convolution rig Matching Bits.
The length of described steel bushing is 900mm.
The lower end surface of described steel bushing is welded with 12 described carbide button heads.
The present invention is by convolution drill bit outer setting steel bushing arrange carbide button head at the lower end surface of steel bushing, utilize steel bushing lower surface equally distributed high-strength alloy tooth head to carry out mill to uneven geology to cut, the soil body is fixed in sleeve by recycling steel bushing, then drill bit cutting soil is utilized to carry out drilling construction, can creep into by smooth vertical when effectively can ensure that drill bit runs into uneven geological condition, ensure the hole quality of bored pile under uneven geological condition, ensure that the quality of pile foundation, thus efficiently solve existing abrasion drill drill bit easily occur hole scattering under uneven geological condition, reinforcing cage cannot divide into the technical barrier of installation, in addition, structure of the present invention is simple, and principle is understandable, and processing and fabricating is simple, draws materials conveniently, with low cost, has very high practicality.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram in the specific embodiment of the invention;
Fig. 2 is the lateral view of Fig. 1;
In figure, 1 is drill bit leg, and 2 is steel bushings, and 3 is carbide button heads, and 4 is convolution drill bits.
Detailed description of the invention
Below by non-limiting embodiment, also the present invention is further illustrated by reference to the accompanying drawings:
As shown in drawings, a kind of abrasion drill drill bit device processing uneven geology, comprise convolution drill bit 4, the outer cover of described convolution drill bit 4 is equipped with steel bushing 2, convolution drill bit 4 is positioned at the inside of steel bushing 2, the cylindrical of drill bit leg 1 and the upper end inside wall of steel bushing 2 of convolution drill bit 4 weld together, the lower end surface of steel bushing 2 is welded with the carbide button head 3 of several high strength along its even circumferential, in the present embodiment, the length of steel bushing 2 is 900mm, the lower end surface of steel bushing 2 is welded with 12 equally distributed described carbide button heads 3.
Convolution drill bit 4 in the present embodiment is prior art, and it is also provided with carbide button head 3, and convolution drill bit 4 can adopt convolution rig Matching Bits, also can custom-made processing.Steel bushing 2 in the present embodiment can adopt Q235 steel plate, adopts plate bending rolls machine-shaping.
Be connected with convolution rig when the present invention uses, and construct according to convolution Construction technology of bored pile, its hole quality is high, effectively can ensure the quality of pile foundation.
Other parts in the present invention adopt prior art, do not repeat them here.
