Description
Technical field
The present invention relates to technical field of civil engineering, and in particular to a kind of repeatable with new screw filling pile construction machine
Tool.
Background technology
At present, make pile foundation and mainly use country-level engineering method -- half screw bored concrete pile technology, but actually used
During, find this complicated geological structure that adaptation southwest is difficult into spiral shell section, this area mountains and rivers, tributary many ground qualitative change
Change big, formation strength is changed greatly, stratum is widely different because of frequently flood alluviation, and unlike North Plain, that is machine-made
Argillic horizon and without obvious supporting course, is very easy to into spiral shell, it is impossible to meet screw rod pile simultaneous techniquess.But can not synchronously
Complete screw rod pile cannot be made.
The soil structure in southwest major part river is back fill course, backfill rock ballast layer, argillic horizon, silty soil layer, powder
Layer of sand, middle layer of sand, slightly close boulder bed, in close sandy gravel, Compact sandy-pebble, severely-weathered shale, middle weathered shale, possess geology multiple
The characteristics of miscellaneous and level of ground water is higher.In prior art, screw rod pile technique possess have be not afraid of subsoil water, mud, drift sand, without heavy
Slag, without broken pile, noiselessness, environmental protection advantage, but the complicated geological of southwest is difficult into spiral shell.
Content of the invention
It is an object of the invention to：For above-mentioned southwest complicated geology and level of ground water higher so that half screw perfusion
Into the problem that spiral shell is difficult, screw rod pile is unstable, the present invention provides a kind of repeating and uses new screw filling pile construction machine pile work method
Tool.
The technical solution used in the present invention is as follows：
A kind of repeatable with new screw filling pile construction equipment, including outer tube body and inner prop cylinder, the outer tube pipe
Body upper end is provided with outer tube neck ring and enters concrete mouth, and lower end is provided with helical blade；The inner prop cylinder upper end is provided with suspension hook, under
End is provided with drill bit.
Further, the outer tube body, helical blade and drill bit are made using high-carbon steel.
Further, the outer tube body upper end is provided with outer tube connecting hole, is provided with inner prop company on the inner prop cylinder
Connect hole, and two ends insertion.
Further, the outer tube connecting hole and inner prop connecting hole orifice position, size are consistent, and are placed with connection
Post.
Further, the connection column length is much larger than outer tube outer tube diameter.
Further, the outer tube body is tubular structure, and the outer tube outer tube diameter is between 400mm-850mm.
Further, the inner prop cylinder is cylinder, and the drill bit is set to taper.
Further, the inner prop cylinder external diameter is consistent with outer tube internal diameter of tube body.
In sum, as a result of above-mentioned technical proposal, the invention has the beneficial effects as follows：
Solve the collapse hole of the pile foundations such as rotary digging stake, sediment thickness, broken pile, level of ground water high cannot pore-forming and concrete excess difficulty
Topic.

Specific embodiment
All features disclosed in this specification, in addition to mutually exclusive feature and/or step, can be with any
Mode is combined.
The present invention is elaborated with reference to Fig. 1, Fig. 2.
As shown in Figure 1 and Figure 2, it is axonometric chart of the invention and profile.This construction equipment mainly includes
A kind of repeatable with new screw filling pile construction equipment, including outer tube body 6 and inner prop cylinder 2, the outer tube
6 upper end of body is provided with outer tube neck ring 5 and enters concrete mouth 3, and lower end is provided with helical blade 8；2 upper end of inner prop cylinder is provided with
Suspension hook 1, lower end are provided with drill bit 9.The outer tube body 6, helical blade 8 and drill bit 9 are made using high-carbon steel.Described
6 upper end of outer tube body is provided with outer tube connecting hole 4, is provided with inner prop connecting hole 10, and two ends insertion on the inner prop cylinder 2,
8 pitch of helical blade is less, and screw thread is closeer.
Actually used flow process is as follows：
(1) inner prop 2 is arranged in outer tube 6, makes outer tube connecting hole 4 and inner prop connecting hole 10 align, and by connecting pole 11
It is placed in outer tube connecting hole 4 and inner prop connecting hole 10；
(2) filling pile construction equipment is placed into specified location；
(3) power set are fixed on connecting pole 11, start power set, make to be rotated under construction equipment clockwise direction
Hole is shaped to designated depth；
(4) connecting pole 11 is extracted, inner prop 2 is extracted by suspension hook 1 using crane；
(5) connecting pole 11 is inserted to outer tube connecting hole 4, and power set are fixed on connecting pole 11；
(6) concrete is extruded using the extruding of concrete machine from 6 bottom of outer tube, and rotate counterclockwise carries outer tube 6, keep outer tube 6 and the soil body
Pressure differential, it is impossible to interrupt the output of concrete, persistently output concrete is so as to forming lower end screw-type stake；
(7) after outer tube rising is close to weak soil bottom absolute altitude, it is changed to not rotate from rotation and directly carries, stake pressure injection is completed until upper end,
Form linear type stake and extract outer tube 6.
Wherein, the effect of outer tube neck ring 5 is mainly limiting construction equipment submergence depth, it is to avoid it is excessively loose soil layer occur, causes
The situation that construction equipment infinitely sink.
This construction equipment is strengthened power section, strengthens screw rod rigidity and strength of joint, improvement pile top, can be by the supporting course of stake
Close boulder bed, closely knit boulder bed or middle air slaking rammell in being directly placed into.
In sum, screw rod soil compaction, squeeze gravel and piles set into rock engineering method and solve during former screw rod pile driving construction hardly enters
Close boulder bed, closely knit boulder bed, a difficult problem for middle air slaking lithosphere is cannot be introduced into, and solve close cobble during pile tube can not be entered
The defect of layer, closely knit boulder bed, severely-weathered rammell and middle air slaking rammell.Due to screw rod soil compaction, squeeze gravel engineering method bored concrete pile
It is cast-in-place concrete, and the effectively connection of pile concrete and soil layer makes the calculating sectional area of the collateral resistance of frictional force increase and stake
Increase, its collateral resistance, end resistance are better than pile tube with aobvious.Solve the collapse hole of the pile foundations such as rotary digging stake, sediment thickness, broken pile, subsoil water
Position high cannot pore-forming and concrete excess a difficult problem.
