Abstract

The invention discloses an abrasion drill bit device for processing the uneven geology and belongs to the technical field of pile foundation construction. The abrasion drill bit device comprises an abrasion drill bit and is characterized in that the abrasion drill bit is sleeved with a steel sleeve (2), an outer circle of a drill bit surrounding wall (1) of the abrasion drill bit is fixedly connected with the inner side wall in the upper end of the steel sleeve (2). Multiple alloy teeth (3) are evenly arranged on the periphery of the lower end face of the steel sleeve (2). The abrasion drill bit device is simple in structure and capable of effectively ensuring that when the drill bit encounters the uneven geology, the drill bit can proceed stably and vertically, thus, the quality of a formed hole is ensured and the quality of a pile foundation is ensured. The abrasion drill bit device for processing the uneven geology is simple in structure, simple in principle, low in cost and high in practicability and materials are convenient to obtain.

Description

A kind of abrasion drill drill bit device of processing inhomogeneous geology
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 of using while adopting abrasion drill to carry out pile foundation construction in inhomogeneous geology situation, belongs to pile foundation construction technical field.
Background technology
Most bridge foundation adopts pile foundation, and pile foundation is the bored piles that adopt convolution drilling machine construction more.Drilled pile is in work progress, because geological condition can not be all desirable uniformity soil layer, and while running into inhomogeneous geology situation during the construction of existing abrasion drill, in drilling process, easily cause drill bit to oblique compared with weak soil matter one lateral deviation, cause pore-forming deflection, reinforcing cage cannot divide into the situations such as installation, directly affect the quality of pile foundation.
Summary of the invention
For the above-mentioned defect existing in prior art, the invention provides a kind of abrasion drill drill bit device of processing inhomogeneous geology that can be used in, utilize it to hole, when running into inhomogeneous geology situation, can guarantee that drill bit steadily vertically creeps into, guarantee hole quality.
The present invention is achieved by the following technical solution: a kind of abrasion drill drill bit device of processing inhomogeneous 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, on the lower end surface of described steel bushing, along its even circumferential, is provided with several carbide button heads.
The present invention utilizes equally distributed high-strength alloy tooth head on steel bushing lower end surface that inhomogeneous geology is ground and cut, and recycling steel bushing is fixed on the soil body in sleeve, then utilizes drill bit cutting soil to carry out drilling construction.Acting as of steel bushing: can guarantee when drill bit runs into inhomogeneous geology situation steadily vertically to creep into, can guarantee hole quality.Convolution drill bit in the present invention can adopt convolution rig Matching Bits.
The length of described steel bushing is 900mm.
On the lower end surface of described steel bushing, be welded with 12 described carbide button heads.
The present invention is by arranging carbide button head at convolution drill bit outer setting steel bushing and at the lower end surface of steel bushing, utilize steel bushing lower surface equally distributed high-strength alloy tooth head that inhomogeneous geology is ground and cut, recycling steel bushing is fixed on the soil body in sleeve, then utilize drill bit cutting soil to carry out drilling construction, can effectively guarantee can steadily vertically creep into when drill bit runs into inhomogeneous geology situation, guarantee the hole quality of bored pile in inhomogeneous geology situation, guaranteed the quality of pile foundation, thereby efficiently solve existing abrasion drill drill bit and be prone to hole scattering in inhomogeneous geology situation, reinforcing cage cannot be divided into the technical barrier of installation, in addition, the present invention is simple in structure, 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, the 1st, drill bit leg, the 2nd, steel bushing, the 3rd, carbide button head, the 4th, convolution drill bit.
The specific embodiment
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 of processing inhomogeneous 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, on the lower end surface of steel bushing 2, along its even circumferential, be welded with several high-intensity carbide button heads 3, in the present embodiment, the length of steel bushing 2 is 900mm, is welded with 12 equally distributed described carbide button heads 3 on the lower end surface of steel bushing 2.
Convolution drill bit 4 in the present embodiment is prior art, is also provided with carbide button head 3 on it, 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.
When the present invention uses, be connected with convolution rig, and according to the construction of convolution Construction technology of bored pile, its hole quality is high, can effectively guarantee the quality of pile foundation.
Other parts in the present invention adopt prior art, do not repeat them here.
