Abstract
A kind of quick construction method for abolishing filling pile head, its step is to entangle on every main reinforcement top of steel reinforcement cage with sleeve pipe, and seal sleeve pipe upper and lower ends port, then pile foundation filling concrete is carried out, until exceeding design of pile top absolute altitude, when being poured at stake top absolute altitude, embedded bar suspension ring in pile crown concrete more than stake top absolute altitude, after pile concrete solidification, the pile crown surrounding earthwork is dug out, measure and identify need cut a stake position, along mark at border uniformly drilling after with splitter separate pile crown concrete, pile crown concrete is hung out and transported.Present invention efficiently solves the damage in work progress to reinforcing bar and pile body, efficiency of construction is improved, ensure that construction quality.
Description
Technical field
The present invention relates to building construction cast-in-place pile construction method technical field, and in particular to one kind quickly abolishes grout pile
The construction method of head.
Background technology
When pouring into a mould bored concrete pile, in process of vibrating, aggregate sinks concrete, and it is upward that cement mortar carries bubble
Return, cause stake top concrete strength relatively low.To ensure pile foundation concrete strength, after the completion of pile foundation pours, it will be above stake top and set
Reinforcing bar is exposed in the pile crown part of meter absolute altitude after abolishing, and then uses the reinforcing bar of bar connecting upper strata suspended deck structure, progress superstructure
Pour.Currently used pile crown restructuring bankrupt is：Manually it is aided with small machine to cut, or pile crown is adopted in designed elevation position
Ring cutting is carried out with abrasive machine, then artificial chisel removes the cover concrete of pile crown, and cage bar peeled off into concrete from lateral, then by stake
The piecemeal cleaning of head concrete.Bending can be caused to damage when so causing to cut pile crown to reinforcing bar, easily cause reinforcing bar from bottom break,
It need to weld again.This construction method work efficiency is low, it is difficult to ensures that pile crown abolishes the construction quality of rear reinforcing bar, and needs a large amount of work
Power, have a strong impact on construction quality and progress.
The content of the invention
It is effective to solve to construct it is an object of the invention to provide a kind of quick construction method for abolishing filling pile head
To the damage of reinforcing bar and pile body in journey, efficiency of construction is improved, ensures construction quality.
The technical scheme that the present invention takes is as follows：
A kind of quick construction method for abolishing filling pile head, comprises the following steps：
(1) every main reinforcement top of steel reinforcement cage is entangled with sleeve pipe, and seals sleeve pipe upper and lower ends port；
(2) pile foundation filling concrete is carried out, until exceeding design of pile top absolute altitude；When being poured at stake top absolute altitude, in stake
Embedded bar suspension ring in pile crown concrete more than top mark is high；
(3) after pile concrete solidification, the pile crown surrounding earthwork is dug out, measuring and identifying needs to cut stake position；
(4) needing cut stake site marking at, along mark at border uniformly drilling after with splitter separate pile crown coagulation
Soil；
(5) pre-buried reinforcing bar suspension ring are hooked with lifting appliance, pile crown concrete is hung out, transports pile crown.
Step (1) described sleeve pipe internal diameter of the present invention is thicker 3~5mm than reinforcing bar, is fastened and is sealed above and below sleeve pipe using iron wire
Both ends port.
Compared with existing construction method, the present invention has advantages below：
A. pile crown departs from pile body by overall vertical lifting upwards, can effectively avoid during Stake head handling to the damage of reinforcing bar
Wound, makes cage bar parallel, does not bend, and realizes the soap-free emulsion polymeization between the concrete that need to remove；
B. pile crown is integrally hung out upwards, can reduce and pile concrete is impacted or damaged, it is ensured that pile foundation and cushion cap it
Between connection；The construction speed for abolishing filling pile head is improved, reduces the labor intensity of workmen；
C. ensure construction quality, and avoid the dust pollution surrounding environment that traditional broken pile head cuts concrete, improvement is manually applied
Work operating environment.
D. construction and installation of the present invention are convenient, and are remarkably improved efficiency of construction.
Brief description of the drawings
Fig. 1 is that every cage bar top puts plastic bushing and pre-buried suspension ring schematic diagram；
Fig. 2 is pile crown concrete separation schematic diagram；
Fig. 3 is that pile crown concrete carries out hanging out schematic diagram；
Fig. 4 is the view after pile crown concrete removes.
Embodiment
A kind of quick construction method for abolishing filling pile head, comprises the following steps：
(1) as shown in figure 1, in steel reinforcement cage processing and fabricating, stake top absolute altitude above section is located to cage bar 1 without curved
Folding, keeping parallelism state；Every cage bar is located at stake top absolute altitude (in Fig. 1 at horizontal line A) above section and is inserted in sleeve pipe 2, sleeve pipe is adopted
Tightened with soft plastic tube, and by two mouthfuls above and below sleeve pipe using iron wire winding, it is make pile crown reinforcing bar and perfusion mixed that it, which is acted on,
Do not bonded between solidifying soil；Casing inner diameter is thicker 3~5mm than reinforcing bar；
(2) pile foundation filling concrete is carried out, until exceeding design of pile top absolute altitude；As shown in Figure 1 and Figure 2, it is being poured into stake top
When at absolute altitude, the pre-buried reinforcing bar suspension ring 3 for meeting pile crown integral hoisting force request in the pile crown concrete more than stake top absolute altitude,
Expose on pile crown top of concrete the upper end of reinforcing bar suspension ring 3.Reinforcing bar suspension ring are used for hanger when pile crown removes；
(3) when the intensity that pile concrete is solidified to concrete reaches the 30% of design strength, by the pile crown surrounding earthwork
Dig out, and the position for needing to cut stake position is measured and identified according to the designed elevation of bored concrete pile, needing the position at section stake position
Do line mark in place；
(4) as shown in Fig. 2 needing to cut at the site marking of stake, cutting machine is used along after tag line B borders uniformly drilling 4
Pile crown bottom is cut along tag line border, separates the concrete of pile crown 5 with splitter afterwards；
(5) it is overall vertically to sling and remove pile crown 5 as shown in figure 3, hooking pre-buried reinforcing bar suspension ring 3 with lifting appliance, cover
Pipe 2 is removed together with pile crown.Bored concrete pile state after pile crown removes is as shown in Figure 4.To remaining filling pile head top surface
After carrying out manual amendment, you can constructed into next procedure.
Claims (2)
1. a kind of quick construction method for abolishing filling pile head, it is characterised in that comprise the following steps：
(1) every main reinforcement top of steel reinforcement cage is entangled with sleeve pipe, and seals sleeve pipe upper and lower ends port；
(2) pile foundation filling concrete is carried out, until exceeding design of pile top absolute altitude；When being poured at stake top absolute altitude, in stake top mark
Embedded bar suspension ring in pile crown concrete more than high；
(3) after pile concrete solidification, the pile crown surrounding earthwork is dug out, measuring and identifying needs to cut stake position；
(4) needing cut stake site marking at, along mark at border uniformly drilling after with splitter separate pile crown concrete；
(5) pre-buried reinforcing bar suspension ring are hooked with lifting appliance, pile crown concrete is hung out, transports pile crown.
A kind of 2. quick construction method for abolishing filling pile head according to claim 1, it is characterised in that step (1)
Described sleeve pipe internal diameter is thicker 3~5mm than reinforcing bar, is fastened using iron wire and seals sleeve pipe upper and lower ends port.
