Embodiment two
Shown in Figure 11 to Figure 19, the present embodiment three provides a kind of Power compound drilling tools more according to embodiment one again to make
The method of standby type stake 4 comprising: the demand according to stratum to engineering method and leads position connection at the upper power drilling tool 1, middle power drilling tool 2
Dynamic drilling tool 3 is successively drilled into respective projected depth successively；Start concrete pump 5, start pressure concrete injecting, upper power is successively promoted in pressure concrete injecting
Drilling tool 1, middle power drilling tool 2 and position linkage drilling tool 3 is led, until Synchronous lifting goes out aperture absolute altitude after each drilling tool bottom end is successively concordant,
Concrete, which is also pressed, simultaneously fills pile to designed elevation.
In the treatments of soft foundation such as building structure or railway, highway, need to carry out the foundation soil of disposal field soil from shallow to deep
According to mean shear wave velocity value changing rule can generally be divided into Soft site soil (soil layer average clearance method≤140m/s), in
Soft Site Soil (140m/s < soil layer average clearance method≤250m/s), native (the 250m/s < soil layer average shear wave of Moderate stiff soil sites
Speed≤500m/s), hard ground it is native (500m/s < soil layer shear wave velocity).
For diameter-variable pile:
Such as: it is Moderate stiff soil sites soil (or the overwhelming majority is Moderate stiff soil sites soil) for stratum in the processing long range of stake, adopts
With casting engineering method, casting pore-forming is successively crept by center drilling tool 12- intermediate sleeve drilling tool 22- outer sleeve drilling tool 32 respectively.Into one
Step, this kind of 15 pressure point of process flow pressurizing device is set on power head 11 most preferably.
Such as: for stratum in the processing long range of stake be it is weak, in soft Site Soil (or the overwhelming majority it is weak, in soft field
Ground soil), using soil compaction engineering method, soil compaction is successively crept by center drilling tool 12-intermediate sleeve, 22-outer sleeve of drilling tool drilling tool 32 respectively
Pore-forming.Further, this kind of 15 pressure point of process flow pressurizing device is set on power head 11 most preferably.The first variable diameter of stake top
Casting mode (mainly seeing intermediate sleeve drilling tool 22 to the compacted degree of hole wall soil) also can be used in pile body pore-forming engineering method.
Such as: handling stratum top in the long range of stake is soft Site Soil in weakness-, and lower part is Moderate stiff soil sites soil, using crowded
Engineering method is had both in casting, and by intermediate sleeve drilling tool 22, (drilling tool 12 drill bit in center stretches out 22 bottom end of intermediate sleeve drilling tool at this time, when drilling
For reversion, spin-ended casting is prevented, only play as the positioning of intermediate sleeve drilling tool 22, break ground and creep into function)-outer sleeve drilling tool 32 is successively
Soft Site Soil creeps into soil compaction pore-forming in weakness-respectively, and (or 22 bottom end of intermediate sleeve drilling tool slightly penetrates soil compaction area) stops boring, so
It is rotated forward afterwards by center drilling tool 12, continues drilling rotation casting into stake holes, reach projected depth in Moderate stiff soil sites soil.Further,
Stake top the first variable diameter pile body pore-forming engineering method also can be used casting mode and (mainly see intermediate sleeve drilling tool 22 to the compacted journey of hole wall soil
Degree).This kind of 15 pressure point of process flow pressurizing device is set on middle power head 21.
For screw thread diameter-variable pile:
Such as: in the processing long range of stake stratum be it is weak, in soft Site Soil (or the overwhelming majority it is weak, in soft place
Soil), using partial threads soil compaction engineering method, by center drilling tool 12 using simultaneous techniques drilling soil compaction at screw thread stake holes；Intermediate sleeve
The extruding and removing soil drilling tool drilling and forming hole based on soil compaction is successively respectively adopted in 22-outer sleeve of drilling tool drilling tool 32.Intermediate sleeve drilling tool
22, outer sleeve drilling tool 32 it is weak, in soft Site Soil drilling reach projected depth after stop boring, (intermediate sleeve drilling tool 22, outer sleeve
For drilling tool 32 when soil compaction area pore-forming is crept into, drilling tool 12 drill bit in center stretches out 22 bottom end of intermediate sleeve drilling tool, is reversion when drilling, prevents
Only soil is drained into outside aperture by the rotation of center drilling tool 12, only plays as intermediate sleeve drilling tool 22, the positioning of outer sleeve drilling tool 32, drilling of breaking ground
Function), it is then rotated forward by center drilling tool 12, using simultaneous techniques drilling soil compaction at screw thread stake holes.Further, this kind of technique stream
15 pressure point of journey pressurizing device is set on middle power head 21.Further, the first variable diameter of stake top pile body pore-forming engineering method can also adopt
With casting mode (mainly seeing intermediate sleeve drilling tool 22 to the compacted degree of hole wall soil).

In addition, for main body pile body 41, it can also be there are many form.
For example, non-threaded type diameter-variable pile: there are two back taper stepped ramp type body 42, the back tapers for setting on the main body pile body 41
The angle 5 °~900 of place inclined-plane extended line and 41 central axis of main body pile body at the variable diameter of stepped ramp type body 42.
In another example screw-type diameter-variable pile: there are two back taper stepped ramp type bodies 42 for setting on the main body pile body 41, from top to bottom
It is divided into the first pile body, the second pile body and third pile body, wherein third pile body has helicitic texture.The back taper stepped ramp type body 42
The angle 5 °~900 of place inclined-plane extended line and 41 central axis of main body pile body at variable diameter.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme.
