Description
Technical field
The invention belongs to building construction fields, specifically design a kind of filling pile head construction method.
Background technique
Currently, bored concrete pile is commonly used to the every field of engineering construction, it is the pile body type being most widely used.To avoid
In concrete perfusion, the impurity precipitated in mud in the sediment and filling process at stake bottom can form certain thickness in concrete surface
Degree, guarantees the quality of pile crown, wherein taking a superfilled segment length to bored concrete pile, and becomes in the mode that the later period abolishes superfilled pile head
Guarantee one of important measures of pile driving construction quality.
It is due to concrete intensity height itself and big with bonding strength, cause pile crown and pile body to disconnect difficult.Pole in disconnection process
The problems such as easily causing pile body vertical and oblique crackle, pile crown absolute altitude error and flatness, or even cause pile crown too low, it influences to carry
Power.Also the investment for virtually increasing equipment and manpower, reduces construction and business efficiency；Pneumatic pick long working simultaneously, makes an uproar
Sound is big, and dust is more, seriously polluted to the shadow of environment.In addition, bending deformation reduces tensile strength, pile body when main reinforcement pulls out
Junction between cushion cap is weakened, and is hidden some dangers for construction quality.It carves the pile crown lifting removed and transport is also extremely difficult, due to stake
Leader is high and flatness is unable to control, and finally also needs manually to divide exactly pile crown.In order to increase Bar Anchorage, last pile crown reinforcing bar needs curved
45 degree bent, the artificial bending in scene is difficult.
Current existing construction technology not can solve pile crown in the prior art and pile body disconnection is difficult, in disconnection process easily
Cause pile body vertical and oblique crackle, pile crown absolute altitude error and flatness, the problems such as pile crown lifting is difficult, and bar bending is difficult.
Summary of the invention
In view of the above technical problems, the purpose of the present invention is to provide a kind of filling pile head construction methods, for solving
Pile crown and pile body disconnect difficult problem in the prior art.
To achieve the above object, the technical solution used in the present invention is:
A kind of filling pile head construction method, it is characterised in that the following steps are included:
S1, it after first processing, binding filling pile cage of reinforcement to designed elevation position, is welded three or more steel reinforcement cage main reinforcement upper ends
Lower part positioning bar, will division ring set in steel reinforcement cage main reinforcement, then in the steel reinforcement cage main reinforcement above splitting ring weld three with
On top positioning bar splitting ring is clamped；
S2, more than four splitting pipes are fixed on splitting ring, more than four splitting pipes are arranged along stake radial symmetric；
S3, upper disrance sleeve is covered at the top of every steel reinforcement cage main reinforcement；
S4, foamed glue is filled in splitting pipe, disrance sleeve respectively, sleeve cap is covered in disrance sleeve upper end；
Pile crown is exposed at S5, the reinforcing bar hanging ring that a pair of of ellipse is arranged on the disrance sleeve in the middle part of pile crown, hanging ring both ends, and a pair is hung
Ring is arranged symmetrically；
S6, molding steel reinforcement cage is transferred into design position, then pours cast-in-place pile concrete；
After S7, cast-in-place pile concrete reach design strength, Hydraulic splitter is inserted into splitting pipe, starts Hydraulic splitter for stake
Head is along splitting pipe in division anchor ring fracture；
S8, vertically pile crown is integrally hung out using hanging ring as suspension centre；
S9, splitting pipe, disrance sleeve and splitting ring are cleaned up；
S10, exposed steel reinforcement cage main reinforcement are bent outwardly 45 degree.
Further, the disrance sleeve uses pvc pipe.
Further, the splitting pipe is made of closed at one end, other end setting nut cap pvc pipe, every splitting pipe
Length 20cm.
Further, tongue and groove, the disrance sleeve lower end are equipped at each steel reinforcement cage main reinforcement in the splitting ring upper surface
It is inserted in tongue and groove, the tongue and groove is covered in steel reinforcement cage main reinforcement.
The invention has the benefit that
1, the present invention sets disrance sleeve in the main reinforcement of steel reinforcement cage, guarantees the separation of pile crown concrete and rebar, without repeatedly disturbance
Main reinforcement solves the multiple bending deformation of live main reinforcement, or even the phenomenon that fracture, while can be easily pile crown concrete from main reinforcement
In be stripped out, use manpower and material resources sparingly, while saving the duration.
2, the present invention injects foamed glue in splitting pipe and disrance sleeve, and concrete and main reinforcement can further be isolated, and prevents
Only since pressure flows into disrance sleeve in concreting process.
3, the present invention is equipped with the splitting ring of an annular in design stake top elevation location (position for needing to abolish fracture) in advance,
Make to be formed slight crack annular together between pile crown and pile body；The radial symmetric above splitting ring along stake sets 4 division holes simultaneously, side
Just Hydraulic splitter is to pile head breaking, in combination with splitting ring from fracture mechanics, it is ensured that pile crown from division ring position
Fracture, to effectively control stake top absolute altitude and flatness.
4, splitting ring is equipped with one of tongue and groove around main reinforcement, it can fixed disrance sleeve, while seepage flow can also be increased
Approach prevents concrete from entering disrance sleeve.
5,4 positioning bars are respectively set above and below splitting ring, can prevent in solidifying native casting process due to concrete pressure
Cause splitting ring displacement, inclination.
6, the oval reinforcing bar of setting one, both ends expose stake, a pair of of hanging ring are formd, after later period pile crown is abolished in the middle part of pile crown
It is convenient that pile crown concrete is lifted by crane.
7, disrance sleeve, division hole, splitting ring, positioning bar etc. are all made of live material and are process, and gather materials on the spot, construct
Convenient, stock utilization is high.
8, steel reinforcement cage main reinforcement 1 is isolated with concrete, and along with splitting ring is provided with, entire pile crown, which is abolished, only needs four dividing
It splits pipe and abolishes and pile crown can be separated with pile body, cut without entire pile crown in the previous construction of picture, reduce the later period and abolish workload,
Reduce noise pollution when pile crown is abolished, time saving and energy saving.
