Description
Technical field
The present invention relates to hydraulic engineering fields, and in particular to a kind of filling pile head processing method and the perfusion of Quick Release pile crown
Stake.
Background technology
During pile foundation concrete construction, since bored concrete pile top concrete coarse aggregate sinks, easily there is laitance.It often leads to
Pile crown concrete strength is poor, and stake top absolute altitude is not easily controlled in bored concrete pile casting process.To ensure pile body strong concrete
Pile height usually when pouring is higher than the absolute altitude of design requirement, then manually cut again by degree and stake top absolute altitude, the prior art
Redundance, until designed elevation.There is no a kind of simple and practicable special processors in pile crown cuts construction.
Prior art generally use pneumatic pick is manually cut, is carried out ring cutting using abrasive machine or abolished by large-scale pile crown to set
It is standby to abolish.After using pneumatic pick or abrasive machine, cover concrete is abolished, it is necessary to which main reinforcement is removed concrete, Ran Houzai from lateral
Pile crown is taken out.Rebar surface has screw thread texture convenient for being combined with concrete more.This two methods not only low construction efficiency, and stake
Head is taken out in the process often because concrete combination is excessively firm, and the reinforcing bar of impact bending, is easy to cause reinforcing steel bar bear fracture.Reinforcing bar is
Just it is not broken, reduces intensity due to also can be because fatigue yield after plate again is straight.
In particular, manually punching or ring cutting grooving after, it is similary easily because of break up location of punchinging when being lifted to pile crown
The problems such as offset, pile crown were combined jail with pile body or reinforcing bar makes pile crown and reinforcing steel bar bear uneven, pile body is triggered to be undermined reinforcing bar curved
It is bent.Meanwhile equipment not only cost height is abolished using large-scale pile crown, it is more serious to the nocuity of reinforcing bar greatly because abolishing power.
The content of the invention
In order to solve the problem of that above-mentioned prior art Stake head handling efficiency is low, cost is high big to reinforcing bar injury, the present invention carries
Not only easy to operate for a kind of filling pile head processing method and Quick Release pile crown bored concrete pile, construction efficiency is high；And it can protect
Reinforcing bar safety, ensures pile body pile quality.
The purpose of the present invention can be realized by following technical proposal：A kind of filling pile head processing method, construction procedure
Including：
1. setting bored concrete pile framework of steel reinforcement with matching in fill orifice, the pile body portion of the framework of steel reinforcement includes erecting
To reinforcing bar and stirrup, the pile crown portion of the framework of steel reinforcement includes vertical reinforcement；
2. setting steel bar sleeve on the vertical reinforcement in the pile body portion, frame is laterally set on the stirrup on pile body portion top
Vertical reinforcing bar, makes the cableway between filling pile head and pile body；
3. installing empty slot template on the cableway, make stake of the empty slot template-setup above bored concrete pile pile body
Head bottom is arranged between filling pile head and pile body, and the empty slot template is in center pair compared with the pile body axle center
Claim；
4. the concrete perfusion pile into fill orifice；
5. jack is set in the empty slot template, compared with the pile body axle center in center at the jack jacking
Symmetrically, jack between pile crown and pile body into flush joint；
6. fixing pile crown concrete by empty slot in empty slot template and flush joint, pile crown concrete is vertically separated with pile body.
Preferably, the empty slot template-setup has at least two groups intersected in pile body axle center.The empty slot template is in pile body
Being evenly distributed in the upper surface is evenly distributed with formed reserved through hole, and from through hole, jacking contributes to pile crown bottom surface uniform stressed.
Preferably, the empty slot template includes upper frid and lower frid, and the upper frid is opposite with the lower frid to be fastened
Into through hole.It is furthermore preferred that the through hole crosses bored concrete pile after pile.The split type empty slot template can be in jacking process
In preferential separation up and down, promote being further formed for flush joint, avoid local stress between pile crown and pile body excessive, anarchial cleavage occur
Line.
Preferably, jack at least described in two groups is provided with described in every group in empty slot template, is symmetrically arranged in the group
The both ends of empty slot template inner via hole.
Preferably, the jack is separated type hydraulic jack.The more preferably slim jack or ultra-thin of the jack
Type jack.
The present invention also provides a kind of bored concrete piles with Quick Release pile crown constructed using above-mentioned processing method.
According to the present invention, empty slot template is fixed by the cableway in stirrup, by bored concrete pile physics be divided into advance pile body and
Pile crown two parts, and pass through steel bar sleeve and avoid pile crown concrete adhesion.It is formed after pile is perfused, in the empty slot template pre-
Through hole is stayed, avoids later stage caused bored concrete pile pile body irregularly impaired or reinforcing bar lateral bending when drilling.In the jacking of jack
Under effect, concrete uniform stressed tension failure that pile crown is made to be connected with pile body forms uniform flush joint, pile crown is avoided laterally to crush
Or reinforcing bar caused by lifting load unevenness is lateral stressed, further facilitates follow-up vertical lifting.
Resultant effect includes caused by the present invention：
1st, pile crown disposably abolishes success rate height stage by stage.Slim at present/ultrathin jack good application effect, jacks energy
Power is met the requirements, and by bored concrete pile of the present invention, can disposably manufacture flush joint between pile crown and pile body.
2nd, construction efficiency is high.Mutually more conventional artificial pneumatic pick does the processing modes such as hole, abrasive machine ring cutting, present invention construction speed
It spends fast, efficient and more laborsaving.
3rd, material, equipment are simple and easy to get, low cost, repeat and utilize.Mutually relatively large Stake head handling equipment, the present invention relates to
Main material be reserved empty slot template, conventional channel steel, I-steel or plank can be selected from；Main tool is slim/super
Slim jack, it is reusable.Material and instrument are simple, low cost.
4th, avoid generating damage to reinforcing bar and pile body concrete.Effectively protection main reinforcement safety, it is right in Normal practice to avoid
The Bending Damage of main reinforcement.And ensure that pile body concrete reaches design plane height, it will not be accidentally injured by Stake head handling process.
