Description
Technical field
Stake drilling aid under a kind of aqueous geological stratification of water conservancy construction of the utility model, it is related to one kind in water conservancy construction mistake
Cheng Zhong, to the device that stake drilling is aided under aqueous geological stratification, belong to water conservancy construction field.More particularly to a kind of cooperation is existing
Rig carries out the lower stake of aqueous geological stratification drilling, mitigates the device that the soil body avalanche of drill hole inner wall influences.
Background technology
At present, during water conservancy construction, the lower stake that drills can be carried out to ground, to carry out supporting or other work, bored
During hole, the situation that the soil is porous can be run into, is especially all in the aqueous geological stratification area such as beach, soil property from top to down
Loose, because soil property is soft, easily there is the soil body avalanche of drill hole inner wall, after piercing, the soil body sink borehole sealing, makes
Must drill to be used, while drill bit is difficult to withdraw, and existing to use impact drill, the up-and-down movement by drilling tool is entered more
Row drilling, but vibration caused by impacting can aggravate the avalanche of the drill hole inner wall soil body, drilling effect is bad, and when drilling, it is right
The fixation of drilling tool is also problem, is also had using combinationdrill, but combinationdrill complicated, tedious process, inconvenience
In movement, it is very inconvenient to use, and more suitable for large-scale water conservancy construction engineering, for the provisional drilling branch of part
Shield is inapplicable, can not meet the provisional supporting drilling demand of a small range.
The content of the invention
In order to improve the above situation, stake drilling aid provides under a kind of aqueous geological stratification of water conservancy construction of the utility model
It is a kind of to coordinate existing rig to carry out the aqueous lower stake of geological stratification drilling, mitigate the device that the soil body avalanche of drill hole inner wall influences.Knot
Structure is simple, convenient and practical.
Stake drilling aid is realized under a kind of aqueous geological stratification of water conservancy construction of the utility model：This practicality is new
Stake drilling aid bores chamber, storage slag chute, inscribe by main drill bushing, mounting pin, interior cut under a kind of aqueous geological stratification of water conservancy construction of type
Sword, bearing, the axis of guide, spring, installation neck, circumscribed blade and outer tool rest composition, multiple outer tool rests are equal by mounting pin respectively
It is even to be placed on main drill bushing outer wall, installation neck is provided with the outer tool rest, circumscribed blade is placed in installation neck, the outer cut
Hangnail is equipped with piece, is uniformly equipped with multiple interior cutting blades on the main drill bushing inwall, the main drill bushing be built-in with cut brill chamber, it is described
Bearing outer ring is provided with least two and extends radially through groove, and described axis of guide one end is fixed on the end face of main drill bushing, and the other end is from axle
Extending radially through in groove on bearing outer-ring passes, and spring is cased with the axis of guide, spring is between main drill bushing and bearing.It is described
Storage slag chute is provided with main drill bushing inwall, the depth of the storage slag chute close to bearing one end to the other end from gradually increasing.
In use, when carrying out stake under water conservancy construction drilling to aqueous geological stratification, bearing outer ring is connected with rig first
Connect, bearing inner race is connected with external pipe, main drill bushing is placed vertically on the ground, rig band dynamic bearing rotates, bearing
Driving main drill bushing to rotate by the axis of guide, while push down on bearing, bearing drives main drill bushing to move down by the axis of guide, from
And in main drill bushing precession ground, main drill bushing drives multiple outer tool rests on outer wall to rotate, and outer tool rest drives circumscribed blade rotation, from
And circumscribed blade is cut the soil layer on the outside of main drill bushing, the interior cutting blade on main drill bushing inwall is carried out to the soil layer in main drill bushing
Cutting, part are cut slag and can entered in storage slag chute, meanwhile, bearing drives pipeline to move down, and pipeline progresses into drilling
It is interior, drill hole inner wall is supported, inwall soil slide is prevented, puts barbed design on the circumscribed blade, can aid in
Circumscribed blade is cut soil layer, is further improved stock-removing efficiency, the design of the storage slag chute, is easy to cut the entrance of slag,
Reach the stake in the case where coordinating existing rig to carry out aqueous geological stratification drilling, mitigate the purpose that the soil body avalanche of drill hole inner wall influences.
Beneficial effect.
First, it is simple in construction, it is convenient and practical.
2nd, cost is cheap, easy to spread.
3rd, the lower stake of aqueous geological stratification drilling, the influence of drill hole inner wall soil body avalanche can be mitigated.
Brief description of the drawings
Fig. 1 is the three-dimensional structure diagram of stake drilling aid under a kind of aqueous geological stratification of water conservancy construction of the utility model.
In accompanying drawing
Wherein part is：Main drill bushing（1）, mounting pin（2）, inside cut brill chamber（3）, store up slag chute（4）, interior cutting blade（5）, bearing
