Processing；
Wherein, the step of handling steel reinforcement cage pile crown position includes: that the top setting in steel reinforcement cage pile body position adds
Strengthening tendons, and pearl cotton casing is arranged in each main reinforcement at steel reinforcement cage pile crown position, and by the suitable for reading of pearl cotton casing and
Lower mouth is blocked；
Step S2 installs steel reinforcement cage after the examination of pile foundation pore-forming in Yu Suoshu pile foundation pore-forming；
Step S3 installs conduit, in casting concrete in pile foundation pore-forming；
Step S4, after pile concrete solidification after, the pile crown surrounding earthwork is dug out, measure and identify need cut a stake position；
Step S5 cuts steel reinforcement cage using ring cutting method along mark；
Step S4 applies horizontal force to pile crown using digging machine, pile crown is separated with pile body.
Above-mentioned pile crown quickly abolishes construction technology, wherein in the step S1, using foaming agent to pearl cotton casing
Suitable for reading and lower mouth blocked.
Above-mentioned pile crown quickly abolishes construction technology, wherein in the step S1, the pearl cotton casing inner diameter is than master
Big 3~the 5mm of the outer diameter of muscle.
Above-mentioned pile crown quickly abolishes construction technology, wherein in the step S1, is consolidated pearl cotton casing using bandage
It is scheduled in main reinforcement.
Above-mentioned pile crown quickly abolishes construction technology, wherein the bandage is plastics bandage.
Above-mentioned pile crown quickly abolishes construction technology, wherein in the step S5, depth of cut is 18~22mm.
Foregoing invention is with the following advantages or beneficial effects:
The invention discloses a kind of pile crowns quickly to abolish construction technology, by cancelling steel reinforcement cage stake when steel reinforcement cage is bound
The tie hoop of head position, and reinforcing rib, and each master at steel reinforcement cage pile crown position are set in the top at steel reinforcement cage pile body position
It is arranged pearl cotton casing on muscle, and the suitable for reading of casing and lower mouth are blocked so that concrete and pile crown main reinforcement is isolated, makes
Soap-free emulsion polymeization intensity between concrete and pile crown reinforcing bar is obtained, to substantially reduce abolishing the construction period for pile crown, and is omitted big
The labour cost of amount had both accelerated the construction speed of pile foundation engineering, also saved the cost that pile crown abolishes construction, had very strong reality
The property used.

Specific embodiment
The structure in the present invention is further described with specific embodiment with reference to the accompanying drawing, but not as this
The restriction of invention.
As shown in Figure 1, the invention discloses a kind of pile crowns quickly to abolish construction technology, specifically, the construction technology includes
Following steps:
Step S1, banding steel cage 1 cancel the tie hoop 5 at 1 pile crown position 11 of steel reinforcement cage, and to 1 pile crown portion of steel reinforcement cage
Position 11 is handled.
Wherein, the step of handling 1 pile crown position 11 of steel reinforcement cage includes: in the top at 1 pile body position 12 of steel reinforcement cage
Reinforcing rib 3 is set, and is arranged pearl cotton casing 4 in each main reinforcement 2 at 1 pile crown position 11 of steel reinforcement cage, and by pearl cotton casing 4
Suitable for reading and lower mouth blocked；So as to will between the main reinforcement 2 and concrete at 1 pile crown position 11 of steel reinforcement cage carry out every
From so that not having the main reinforcement 2 and concrete binding at pile crown position 11, in the step of subsequent pile crown is abolished so as to shorten stake
Head abolishes the construction period.
In the present embodiment, due to eliminating the spiral hoop at 1 pile crown position 11 of steel reinforcement cage in 1 process of binding of steel reinforcement cage
Muscle is only provided with tie hoop 5 on 1 pile body position 12 of steel reinforcement cage, therefore does not have spiral shell in the step of subsequent pile crown is abolished
It revolves stirrup and so as to shorten abolishing the construction period for pile crown, and has saved the material cost of steel reinforcement cage 1 with concrete binding, and
Reinforcing rib 3 is set by the top in 1 pile body position 12 of steel reinforcement cage, can solve due to eliminating 1 pile crown position 11 of steel reinforcement cage
Tie hoop caused by the unstable problem in 1 pile crown position 11 of steel reinforcement cage.
In a preferred embodiment of the invention, the suitable for reading of casing 4 and lower mouth are blocked using foaming agent.
In a preferred embodiment of the invention, above-mentioned 4 internal diameter of casing is 3~5mm bigger than the outer diameter of main reinforcement 2.
In a preferred embodiment of the invention, casing 4 is fixed in main reinforcement 2 using plastics bandage.
Step S2, after the examination of pile foundation pore-forming 1, in installing above-mentioned steel reinforcement cage 1 in pile foundation pore-forming 1；Form such as Fig. 2~4
Shown in structure.
Step S3 installs conduit, in casting concrete in pile foundation pore-forming 1.
Step S4, after pile concrete solidification after, the pile crown surrounding earthwork is dug out, measure and identify need cut a stake position.
Step S5 cuts steel reinforcement cage 1 using ring cutting method along mark, and depth of cut is 18~22mm.
Step S6 applies horizontal force to pile crown using digging machine, pile crown is separated with pile body；Due to eliminating reinforcing bar
The tie hoop at 1 pile crown position 11 of cage, and pearl cotton-padded covering is used between the main reinforcement 2 and concrete at 1 pile crown position 11 of steel reinforcement cage
Pipe 4 is isolated, therefore soap-free emulsion polymeization intensity between pile crown reinforcing bar and concrete, so being applied using digging machine to pile crown horizontal
Power can integrally push over pile crown along ring cutting gap, so that pile crown is separated with pile body, structure as shown in Figure 5.
