Middle sliding cannot slide, the setting of splined shaft 34 solves since driving device (not shown) is bigger in casing 26
This problem.When shaft 3 sinks to certain depth, splined shaft 34 is extracted from connector sleeve 32, then proceedes to pound pile body 1
Sink, when shaft 3 will be exposed, continue to assemble shaft 3, in cycles repeatedly aforesaid operations, until pile body 1 passes through sandy soil
Layer.The section of fin 31 is triangle, so that the endurance of fin 31 is stronger, it is ensured that in the mistake for digging thick and solid sandy soil layer
It is indeformable in journey.Discharge launder 37 is opened up on the outer wall of connector sleeve 32, discharge launder 37 is discharged outside pile body 1 convenient for sandy soil.
With reference to Fig. 1, in the boss 13 of the lower end of pile body 1 setting taper, the contact area of the boss 13 of taper and soil layer is more
It is small, so that the soil compliance conical surface be facilitated to disperse around, further facilitate the sinking of pile body 1.
Referring to figs. 2 and 3, in the drill bit 38 of the lower end of shaft 3 setting alloy, so that drill bit 38 can be thick and solid
Pilot hole is without damaging in sandy soil layer.Counterbore 11 is set in the upper end of pile body 1, fixing sleeve 12 is set in counterbore 11, in fixation
Limit sleeve 35 is threadedly coupled in set 12.T-shaped hole 36 is set in limit sleeve 35, and the butt end of T-shaped hole 36 is accompanied on connector sleeve 32, T
The taper end in shape hole 36 cooperates in shaft 3, so that shaft 3 be prevented to be detached from from limit sleeve 35, limit sleeve 35 is threaded in solid
Surely in set 12, so that limit sleeve 35 be prevented to be detached from from fixing sleeve 12, fixing sleeve 12 is embedded in pile body 1, finally makes shaft 3
Being fixed in pile body 1 will not fall off.Limit sleeve 35 includes two identical semicircular rings 351, so that limit sleeve 35 can be from
Side is connected in shaft 3 and connector sleeve 32, then is threaded in fixing sleeve 12.
With reference to Fig. 4, steel reinforcement cage 2 includes that several axial directions along pile body 1 are arranged reinforcing bar 21, are fixed on 21 inside of reinforcing bar
Inner ring 22, the outer ring 23 for being fixed on 21 outside of reinforcing bar.The setting intubation 27 between inner ring 22 and outer ring 23, intubation 27 is set on
On reinforcing bar 21, and by intubation 27 reinforcing bar 21 is positioned.Reinforcing bar 21 improves the energy of the axial tension resistance of pile body 1
Power, inner ring 22 and outer ring 23 cooperate, and improve the ability of the radial tension resistance of pile body 1, to improve the support energy of pile body 1 comprehensively
Power.
With reference to Fig. 4, along the circumferentially uniformly distributed several reinforcing ribs 24 of the radial direction of casing 26 on casing 26, the two of reinforcing rib 24
End is respectively welded on casing 26 and inner ring 22, to further put on the anti-shearing ability of pile body 1.At the both ends of reinforcing rib 24
Semicircular snap ring 25 is set, and snap ring 25 is located on casing 26 on inner ring 22 convenient for reinforcing rib 24, so that reinforcing rib 24
Quickly it is welded on casing 26 and inner ring 22.
Action process: first by shaft 3 assembly in pile body 1, then by pile body 1 pounded into soil layer into；When there is no sandy soil
When layer, pile body 1, which pounds task of driving piles in underground layer, to be terminated；When encountering sandy soil layer, rotary spacing set 35 makes limit sleeve 35 and sinks
Hole 11 is detached from, and splined shaft 34 is connected on connector sleeve 32, is connected other equipment by splined shaft 34 and is rotated come drive shaft 3,
So that carrying out pilot hole to sandy soil layer, then pile body 1 is pounded into sandy soil layer again.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
