Description
Technical field
The present invention relates to technical field of buildings, and in particular to a kind of method that cast-in-situ bored pile pile crown is abolished.
Background technique
Traditional construction method makes to play the part of out main reinforcement with the artificial of low price, break a heart concrete into pieces, the method encounters wage
Go up or when level of ground water is high, it is time-consuming and draw water costly；Such as by the vertical main reinforcement of stake top concrete segment, wrap up in protective case, every
The concrete chisel of cutting then need to only be broken to the effect that bonds of main reinforcement, can be easy to hang out as honeycomb briquette by disconnected concrete；
The present invention is entangled main reinforcement using plastic tube mainly by the construction of drilled pile pile crown first during screwing steel bars cage completely,
Plastic tube bottom end is bound with tied silk and is blocked.Pile crown is finally integrally hung out to pile crown ring cutting after having poured excavation.
Summary of the invention
Present invention aims at the present invention for time-consuming existing in the prior art and to draw water the problems such as costly, provides one
The method that kind cast-in-situ bored pile pile crown is abolished.
To reach above-mentioned purpose, the technical solution adopted in the present invention is as follows:
A kind of method that cast-in-situ bored pile pile crown is abolished, comprising the following steps:
Step 1: main reinforcement is protected: main reinforcement being protected using plastic tube, isolation steel reinforcement cage and pile crown concrete
Between bonding, plastic tube is protruded into cushion cap and entangles main reinforcement completely, and bottom end is blocked with adhesive tape on the plastic tube, simultaneously
Plastic tube bottom end is bound with tied silk；
Step 2: production circulation hangs muscle: welding round hanging ring, another end reinforced and hook 1 reinforcing bar one end first
Welding, reinforcing bar is connect with steel reinforcement cage to be connected using snap ring, according to the difference of hangs muscle length, adjusts snap ring to control the length of hangs muscle
Degree；2 M16 nuts are welded at the hook mouth of bottom end, and nut is inserted into using the round steel bolt isometric with hangs muscle；
Step 3: steel reinforcement cage installation: when steel reinforcement cage is transferred, according to casing top and stake top absolute altitude, adjusting the length of circulation hangs muscle
The hook that 2 recycle hangs muscle is hooked the reinforcement stirrup on top on the inside of steel reinforcement cage, finally with the reinforcing bar bolt isometric with hangs muscle by degree
It is inserted into screw cap hole；When steel reinforcement cage positions, guarantee vertically, after the completion of drilled pile perfusion, snap ring to be unclamped, bolt is extracted, takes
Hangs muscle is recycled out；
Step 4: the horizontal ring cutting processing of pile crown: after the completion of drilled pile construction, using minitype cutting machine in pile crown elevation location
It carries out ring cutting one week, and in pile crown absolute altitude symmetric position drill two holes hole；
Step 5: carrying out pile crown splitting: being cleaved using the hole that hydraulic splitting machine has been drilled insertion pile crown；
Step 6: progress pile crown, which is hung, to be removed: hang removing to the pile crown that step 5 has cleaved using crane；
Step 7: to progress crotch processing at the top of steel reinforcement cage: being carried out using reinforcing bar of the Portable steel bar bending machine to pile crown curved
Song processing.
From the above technical solution of the present invention shows that, the beneficial effects of the present invention are:
Compared with prior art, the invention has the following advantages that a kind of method that cast-in-situ bored pile pile crown is abolished of the present invention,
Have many advantages, such as apparent save the cost, shortens the construction period, reduce security risk, reduce artificial, raising work efficiency, relatively traditional stake
Head, which abolishes construction, biggish breakthrough.

Specific embodiment
In order to make related personnel know more about technology contents of the invention, now specific embodiment is said in conjunction with institute's accompanying drawings
It is bright as follows.
Referring to Fig.1-Fig. 4, a kind of method that cast-in-situ bored pile pile crown is abolished, comprising the following steps:
Step 1: to the protection of cushion cap main reinforcement is protruded into, reinforcing bar being protected using plastic tube, isolation steel reinforcement cage and pile crown are mixed
Bonding between solidifying soil.Plastic tube is protruded into cushion cap main reinforcement to entangle completely, and bottom end is blocked with adhesive tape on the plastic tube.Together
When wound plastic tube from falling off and spillage, plastic tube bottom end are bound with tied silk to prevent.
Step 2: production circulation hangs muscle, circulation 2 HRB400 φ 20mm reinforcing bars of hangs muscle, snap ring, hook welding assembly and
At.Round hanging ring is welded 1 20mm reinforcing bar one end φ first, the fixation for steel reinforcement cage.Another φ 20mm is end reinforced
It is welded with hook, for hanging steel reinforcement cage.Reinforcing bar is connect with steel reinforcement cage to be connected using snap ring, can according to the difference of hangs muscle length
The length of hangs muscle is controlled to adjust snap ring.Simultaneously to prevent steel reinforcement cage from breaking off relations, in bottom end, hook mouth welds 2 M16 nuts, applies
Working hour uses and is inserted in 2 nuts with the isometric HPB300 φ 10mm round steel bolt of hangs muscle.
Step 3: steel reinforcement cage installation: when steel reinforcement cage is transferred, first according to casing top and stake top absolute altitude, adjusting circulation hangs muscle
Length, the hook that 2 recycle hangs muscles is symmetrically hooked to the reinforcement stirrup (HRB400 φ 20) on top on the inside of steel reinforcement cage, is finally used
In isometric 10 reinforcing bar bolt of the HPB300 φ insertion screw cap hole of hangs muscle.When steel reinforcement cage positions, guarantee vertically, to remove so that pile crown is hung.
After the completion of drilled pile perfusion, snap ring is unclamped, extracts bolt, circulation hangs muscle can be taken out.
Step 4: the horizontal ring cutting processing of pile crown: after drilled pile construction completes excavation of foundation pit, in pile crown elevation location using small
Type cutting machine carries out ring cutting one week.Pile crown absolute altitude symmetric position bore two diameters be 40mm, the hole that depth is 400mm, use
It is cleaved in pile crown.
Step 5: pile crown splitting: 2 hydraulic splitting machines being symmetrically inserted into the hole that pile crown has been drilled and are cleaved, and keeps pile crown de-
From.
Step 6: pile crown, which is hung, to be removed: after the completion of pile crown splitting, being carried out disposable whole hang with 25t crane and is removed.
Step 7: crotch processing at the top of steel reinforcement cage: finally carrying out crotch to pile crown reinforcing bar using Portable steel bar bending machine,
Complete Stake head handling.
The foregoing is merely better embodiment of the invention, protection scope of the present invention is not with above embodiment
Limit, as long as those of ordinary skill in the art's equivalent modification or variation made by disclosure according to the present invention, should all be included in power
In the protection scope recorded in benefit requirement.
Although the present invention has been disclosed as a preferred embodiment, however, it is not to limit the invention.Skill belonging to the present invention
Has usually intellectual in art field, without departing from the spirit and scope of the present invention, when can be used for a variety of modifications and variations.Cause
This, the scope of protection of the present invention is defined by those of the claims.
