Description
Technical field
The present invention relates to highway bridge construction technology of cast-in-place bored field, and in particular to a kind of cast-in-situ bored pile quickly breaks
Except pile crown construction method.
Background technology
During cast bored concrete pile, in process of vibrating, cement mortar carries bubble and returns upwards concrete, so stake top strong concrete
Degree is relatively low, and to ensure pile foundation concrete strength, in perfusion, pile crown highly should be higher than that design stake top absolute altitude 0.5-1.0m, and in pile foundation
After the completion of pouring, the pile crown part that will be above design of pile top absolute altitude is cut, and exposes reinforcing bar, and then held with bar connecting upper strata
The reinforcing bar of platform structure, carries out pouring for superstructure.The work for cutting this part pile crown concrete is called " broken pile head ".Conventional at present
Pile crown cuts method：Manually it is aided with small machine to cut, or ring cutting is carried out using abrasive machine to pile crown in designed elevation position,
Then artificial chisel is except the cover concrete of super envelope pile crown, and cage bar peeled off into concrete from lateral, then by pile crown concrete piecemeal
Cleaning.Existing these pile crowns cut method and have the following disadvantages：
1st, cutting pile crown can cause bending to damage to reinforcing bar；
2nd, binder following pile body cover to reinforcement cracking is easily caused when pile crown cuts or is peeled off, bury the disease of cage bar corrosion
And be difficult to check and make up；
3rd, pile crown cuts low construction efficiency, influences duration progress.
The content of the invention
It is an object of the invention to provide a kind of construction method that can quickly abolish pile crown, in effective solution work progress
Damage to reinforcing bar and pile body, improves efficiency of construction, it is ensured that construction quality.
Technical scheme is as follows：
A kind of cast-in-situ bored pile quickly abolishes pile crown construction method, it is characterised in that comprise the following steps：
(1) steel reinforcement cage processing：During steel reinforcement cage processing and fabricating, cage bar is not bent positioned at stake top absolute altitude above section,
Keeping parallelism state；Every cage bar is inserted in soft sponge protection pipe positioned at stake top absolute altitude above section, and sponge is protected
Pipe two ends tighten；
(2) steel reinforcement cage is installed：When steel reinforcement cage is installed, at design stake top absolute altitude, around and fix one and be cased with plastics
The ring steel wire rope of flexible pipe, and the fag end of ring steel wire rope is located at outside pile foundation concrete to be poured；
(3) poured pile base concrete and pre-buried suspension ring：Pile foundation filling concrete is carried out, the pile crown more than stake top absolute altitude is mixed
Solidifying soil embedded set meets the reinforcing bar suspension ring of pile crown integral hoisting force request, the upper end of suspension ring expose pile crown top of concrete it
On；
(4) after pile foundation concrete reaches design strength requirement, cushion cap foundation ditch is excavated；
(5) after the completion of cushion cap excavation of foundation pit, the fag end of ring steel wire rope is connected with excavator or loop wheel machine, and ring peels off steel
Cord, makes concrete of the steel wire rope during being stripped at ring cutting stake top absolute altitude, and realization carries out ring cutting to pile crown；
(6) along ring cutting position, symmetrical horizontal inserting piling gad block makes pile crown be separated with pile body；
(7) integrally vertically sling by suspension ring with excavator or loop wheel machine and remove pile crown.
The invention has the advantages that：
1st, overall vertical lifting upwards departs from pile body, is prevented effectively from during Stake head handling the damage to reinforcing bar, makes cage bar
It is parallel, do not bend, and realize the soap-free emulsion polymeization and between the concrete that need to remove.
2nd, pile crown is integrally hung out upwards, and reduction is impacted or damaged to pile concrete, it is ensured that between pile foundation and cushion cap
Connection.
3rd, operation is simple, and efficiency of construction is high.
4th, the input of construction equipment is reduced, flexible pipe used in the present invention, steel wire rope are repeatable to be utilized, foam sleeve etc.
Material can gather materials on the spot, and substitute is more, can effective reduces cost.
5th, construction noise and dust are substantially reduced, and construction environment improves, effectively the health of protection workmen.
Brief description of the drawings
Fig. 1 is reinforcement cage structure schematic diagram of the invention；
Fig. 2 is the view after steel reinforcement cage of the present invention is installed；
Fig. 3 is the view after the completion of pile foundation concreting of the present invention；
Fig. 4 is the view after pile crown of the present invention is removed.
Specific embodiment
The cage bar of common steel reinforcement cage pile crown part bends in advance, so as to cushion cap bar connecting.
As shown in figure 1, the present invention is in steel reinforcement cage processing and fabricating, cage bar 1 is not carried out positioned at stake top absolute altitude above section
Bending, keeping parallelism state；Every cage bar is located at stake top absolute altitude (in Fig. 1 at horizontal line) above section and is inserted in soft sponge guarantor
Pillar 2, and the two ends of sponge protection pipe 2 are tightened.Sponge protects tube thickness about 10mm, and its effect makes pile crown reinforcing bar with perfusion
It is non-caked between concrete.
As shown in Fig. 2 the present invention is when steel reinforcement cage is installed, at design stake top absolute altitude, it surround and fixes one and be cased with modeling
Expect the ring steel wire rope 3 of flexible pipe, and the fag end 4 of ring steel wire rope is located at outside pile foundation concrete to be poured.Ring steel wire
Rope can simply be fixed using adhesive tape or the nonmetallic cotton rope easily broken by external force etc with steel reinforcement cage.
As shown in figure 3, when carrying out pile foundation filling concrete, the main part of ring steel wire rope 3 is poured into concrete, but
Its fag end 4 is located at outside pile foundation concrete.When being poured at stake top absolute altitude, buried in the pile crown concrete more than stake top absolute altitude
The reinforcing bar suspension ring 5 for meeting pile crown integral hoisting force request are put, the upper end of suspension ring 5 is exposed on pile crown top of concrete.Suspension ring
It is used as hanger (suspension centre) when being removed for pile crown.
After pile foundation concrete reaches design strength requirement, cushion cap foundation ditch is excavated.After the completion of cushion cap excavation of foundation pit, excavator is used
Or loop wheel machine connects the fag end of ring steel wire rope, and ring peels off steel wire rope, and by steel wire rope, ring cuts during being stripped
Concrete at stake top absolute altitude, realization carries out ring cutting to pile crown.
Along ring cutting position, symmetrical horizontal inserting piling gad block, due to the extremely low characteristic of concrete tensile strength, by symmetrical water
Plug flat beats gad block, pile crown is separated with pile body.
Pile crown is vertically sling and removed with excavator or the entirety of loop wheel machine connection suspension ring 5.State such as Fig. 4 institutes after pile crown removal
Show.After manual amendment being carried out to pile crown top surface, you can enter next procedure construction.
