Description
Technical field
The present invention relates to drilling equipments, and in particular to a kind of square pile drill bit.
Background technique
Currently, the drilling machine in borehole engineering mostly uses greatly circular bite, all pile-type (pouring type) are all using drill bit
360 ° of rotation piling, all cylindrical types of pile-type, only precast square pile can be only achieved square pile requirement, and machine rotation can not the side of getting
Type bored concrete pile, this considerably increases design cost and building cost, cylinder pile " angle of repose " is zero, and square pile angle of repose can be effective
Frictional resistance is increased, the 1/3-1/4 of cylinder pile cost can be reduced under corresponding carrying, can substantially reduce and be built into
Sheet and construction period.
" angle of repose " refers in gravitational field, particle suffered gravity and grain when sliding on the free inclined-plane of powder stack layer
Frictional force, which reaches, between son balances and the maximum angular measured that remains static down.
While being now badly in need of the drill bit of patent of invention a kind of and complete rotary drilling, square hole stake need to be completed and carry out reinforcing bar and
" square pile " of cement grouting squarely.
The patent No. 201410843605.7 discloses a kind of square drilling machine, uses circular bore technology, then uses
Circular hole is drilled to square hole by tulwar, and this method is not only troublesome in poeration, and the used time is longer, and is unfavorable for the meter of square hole size
It calculates.
The patent No. 200620068205.4 discloses a kind of drill-pouring square pile drill bit, although solving square cast-in-situ pile
The problem of, but it is used " reuleaux triangle ", and rotation need to provide square dies when driving piles, and bored square pile is fillet square pile, no
Using only cumbersome and be not able to satisfy the needs of right angle square pile.
Summary of the invention
For above-mentioned deficiency in the prior art, the present invention provides a kind of square pile drillers, effectively to improve the above problem.
In order to achieve the above object of the invention, the technical solution adopted by the present invention are as follows:
A kind of square pile driller, including newel and centre drill, the centre drill be equipped with drill bit, drilling rod and beat soil device, it is described
Centre drill is fixedly connected with the newel, and centre drill generates downward drilling strength with the rotation of newel, described to beat soil
Device starts to rotate, further includes: rotating mechanism, the rotating mechanism and the newel clearance fit；Rectangular former, it is described
Rectangular former is fixedly welded with the rotating mechanism.
This set can make centre drill and rotating mechanism cooperate, and efficiently be crept into using drill bit strength.
Preferably, being equipped with equally distributed rectangular chunking on the outside of the surrounding of the rectangular former.
Preferably, including rectangular cutter, the rectangular cutter and the rectangular molding on the inside of the rectangular former
Device is detachably connected.
Preferably, the length of the rectangular cutter is greater than the height of the rectangular former.
The beneficial effect of this set is rectangular former can be introduced to drilling position, while generating downward cutting
Strength.
Preferably, the rectangular former and the centre drill generate relative motion when rotating.
The beneficial effect of this set is can not only to meet the shape need of square cast-in-situ pile, and easy to implement fast
Victory saves plenty of time and equipment cost.
The invention has the benefit that
Square pile can provide bigger foundation bearing capacity than cylinder pile.Square column angle of repose can effectively increase frictional resistance, in phase
Under the carrying answered, cost is less compared with cylinder pile, substantially reduces building cost and construction period.This example structure is simple, uses
It is convenient.
