The utility model discloses reduced the amount of labour used, improved the pile head efficiency of construction, reduced construction noise, both guaranteed construction quality, reduced construction cost again, improved the workman environmental quality that is under construction simultaneously.
Description
Technical field
This utility model belongs to bridge drilling stake technical field, and in particular to a kind of bridge drilling for being easy to remove pile crown
Stake.
Background technology
In existing bridge drilling stake filling pile construction, need to remove pile crown after the completion of bridge drilling pile driving construction, at present
Conventional pile crown construction method has：Manually coordinated using equipments such as air compressor machine, impact drill, iron hammer, gads and cut, concrete grammar is
Ring cutting is carried out using abrasive machine to pile crown in designed elevation position, then artificial chisel removes super pile crown concrete cover to reinforcement,
Cage bar is peeled off into concrete from lateral, then is drilled in designed elevation position and gad is squeezed into using iron hammer, by pile crown concrete from
Rupture designed elevation position.Low using these method construction efficiency, the Stake head handling time is long, causes the foundation pit construction cycle long, people
Work, machinery expenses are high, waste a large amount of artificial, and the bending of pile crown reinforcing bar can be caused to damage.
The content of the invention
This utility model to solve inefficiency when existing highway bridge drilled pile removes pile crown, machinery, labour cost it is high with
And the technical problem of the bending damage of pile crown reinforcing bar can be caused, there is provided a kind of bridge drilling stake for being easy to remove pile crown.
The technical solution adopted in the utility model is as follows：
A kind of bridge drilling stake for being easy to remove pile crown, including pile body and pile crown, the cage bar at pile crown position do not bend and often
It is cased with a protection sleeve pipe in root cage bar respectively, the length of protection sleeve pipe is matched with the height of pile crown, pile crown and pile body phase
The position of contact radially opens up some groove I along pile foundation, and extender is provided with groove I, and in groove I, extender is externally provided with for blocking up
The timber wedge of plug extender, the pile crown top left and right sides symmetrically opens up a groove II for facilitating insertion into rod iron.
The depth of the groove I for Pile Diameter 1/5 ~ 1/4.
The suspension ring for being easy to lift pile crown are provided with the top of pile crown.
The beneficial effects of the utility model：
1. this utility model realizes pile crown with pile body in Pile Foundations Design elevation location point using the expansive force effect of extender
From reducing the amount of labour used, improve pile crown efficiency of construction, reduce construction noise, both ensure that construction quality, reduced and apply again
Work cost, while improve workman's construction environment quality.
2. this utility model is cased with protecting sleeve pipe in the cage bar at pile crown position, and pile foundation can be protected when pile crown is abolished
Reinforcing bar so that pile foundation reinforcing bar is not destroyed.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure：1- pile bodies, 2- pile crowns, 3- cage bars, 4- protection sleeve pipes, 5- groove I, 6- extenders, 7- timber wedges, 8- rod irons,
9- groove II, 10- suspension ring.
Specific embodiment
As shown in figure 1, a kind of bridge drilling stake for being easy to remove pile crown, including pile body 1 and pile crown 2, the master at 2 position of pile crown
Muscle 3 does not bend and is cased with every cage bar 3 respectively a protection sleeve pipe 4, the length of the protection sleeve pipe 4 and the height phase of pile crown 2
Matching, the position that pile crown 2 is contacted with pile body 1 radially open up some groove I5 along pile foundation, and the depth of the groove I5 is set to
The 1/5 ~ 1/4 of Pile Diameter, is provided with extender 6 in groove I5, in groove I5, extender 6 is externally provided with for blocking extender 6
Timber wedge 7, the 2 top left and right sides of the pile crown symmetrically open up a groove II9 for facilitating insertion into rod iron 8.
For larger drilled pile, pile crown is hung away in order to be able to more reliable, a suspension ring can be also added at the top of pile crown 2
10。
Concrete making of the present utility model and the step of abolish pile crown it is as follows：
Step 1, steel reinforcement cage processing：During steel reinforcement cage processing and fabricating, the cage bar 3 that pile crown 2 is stretched in cushion cap is not bent, and is protected
Parastate is held, and protection sleeve pipe 4 is inserted in every cage bar 3, made between pile crown reinforcing bar and the concrete of perfusion without bonding；
Step 2, reinforcement installation：In reinforcement installation, steel reinforcement cage absolute altitude need to be accurately controlled；
Step 3, excavation of foundation pit；
Step 4, after excavation of foundation pit is in place, in Pile Foundations Design elevation location（The position that i.e. pile body is contacted with pile crown）Along footpath
To drilling, then load extender 6 in hole, blocked using timber wedge 7, pile crown 2 and stake are realized using the expansive force effect of extender 6
Body 1 is separated in Pile Foundations Design elevation location；
Step 5, on pile crown 2, radial bore insertion rod iron 8, hangs steel wire rope, and directly integrally being sling with loop wheel machine removes stake
Head.
This utility model can be protected pile foundation reinforcing bar, reduce recruitment, improve pile crown efficiency of construction, reduce applying when pile crown is abolished
Work noise, both ensure that construction quality, reduce construction cost again, while improve workman's construction environment quality.
