Technical field
The utility model is related to technical field of civil engineering, and in particular to one kind is repeatable to use new screw filling pile construction
Equipment.
Background technology
At present, make pile foundation and mainly use country-level engineering method -- half screw bored concrete pile technology, but in actual use
During, find this is difficult the complicated geological structure of adaptation southwest, this area mountains and rivers, tributary many ground qualitative change into spiral shell section
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, it is impossible to meet screw rod pile simultaneous techniques into spiral shell.But can not synchronously
Complete screw rod pile can not 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 answer
The characteristics of miscellaneous and level of ground water is higher.In the prior art, screw rod pile technique possess have be not afraid of underground water, mud, drift sand, without heavy
Slag, without broken pile, noiseless, environmentally friendly advantage, but the complicated geological of southwest is difficult into spiral shell.
Utility model content
The purpose of this utility model is：For above-mentioned southwest complicated geology and level of ground water is higher so that half screw
Pile work method is irrigated into the problem of spiral shell is difficult, screw rod pile is unstable, the utility model provides a kind of repeat and irrigated with new screw
Pile driving construction equipment.
The technical solution adopted in the utility model is as follows：
One kind is repeatable to use 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 mouthful, 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, which is provided with outer tube connecting hole, the inner prop cylinder, is provided with inner tube company
Connect hole, and two ends insertion.
Further, outer tube connecting hole and inner tube the 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 summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：
Solve the collapse holes of pile foundation such as rotary digging stake, sediment thickness, broken pile, level of ground water height can not pore-forming and concrete excess difficulty
Topic.

Embodiment
All features disclosed in this specification, can be with any in addition to mutually exclusive feature and/or step
Mode is combined.
The utility model is elaborated with reference to Fig. 1, Fig. 2.
As shown in Figure 1 and Figure 2, it is stereogram of the present utility model and profile.This construction equipment, which mainly includes one kind, to be weighed
New screw filling pile construction equipment, including outer tube body 6 and inner prop cylinder 2 are multiplexed, the upper end of outer tube body 6 is provided with outer
Neck circle 5 and enter concrete mouthfuls 3, lower end is provided with helical blade 8；The upper end of inner prop cylinder 2 is provided with suspension hook 1, and lower end is provided with
Drill bit 9.The outer tube body 6, helical blade 8 and drill bit 9 are made using high-carbon steel.
The upper end of outer tube body 6 is provided with outer tube connecting hole 4, the inner prop cylinder 2 and is provided with inner tube connecting hole 10,
And two ends insertion, the pitch of helical blade 8 is smaller, and screw thread is closeer.
Actual use flow is as follows：
(1) inner prop 2 is arranged in outer tube 6, outer tube connecting hole 4 and inner tube connecting hole 10 is alignd, and by connecting pole 11
It is placed into outer tube connecting hole 4 and inner tube 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 is fixed on connecting pole 11；
(6) concrete is extruded from the bottom of outer tube 6 using the extruding of concrete machine, and rotate counterclockwise carries outer tube 6, keeps outer tube 6 and the soil body
Pressure differential, it is impossible to interrupt the output of concrete, persistently export concrete to form the stake of lower end screw-type；
(7) outer tube rises close to after the absolute altitude of weak soil bottom, is changed to not rotate from rotation and directly carries, until upper end stake pressure injection completion,
Form linear pattern stake and extract outer tube 6.
Wherein, the effect of outer tube neck ring 5 is main in limitation construction equipment submergence depth, it is to avoid it is excessively loose soil layer occur, causes
Construction equipment infinitely sagging situation.
This construction equipment strengthens 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 weathering rammell in being directly placed into.
In summary, 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, the problem of middle weathering lithosphere are cannot be introduced into, and solve close cobble during pile tube can not enter
Layer, closely knit boulder bed, severely-weathered rammell and the defect of middle weathering rammell.Due to screw rod soil compaction, squeeze gravel engineering method bored concrete pile
Cast-in-place concrete, and pile concrete and soil layer effective connection make frictional force increase and stake collateral resistance calculating sectional area
Increase, its collateral resistance, end resistance are better than pile tube with aobvious.Solve the collapse hole of pile foundation, sediment thickness, broken pile, the underground water such as rotary digging stake
Position it is high can not pore-forming and concrete excess problem.
