Description
Technical field
The present invention relates to technical field of concrete construction, and in particular to one kind abolishes pile crown method.
Background technique
When pouring, coarse aggregate can sink pile foundation concrete, while cement mortar can float, and then make at the top of pile foundation
Concrete gravel content is accordingly less, is also easy to produce pine top phenomenon, and concrete strength also accordingly reduces, to guarantee pile foundation pouring quality
And intensity abolishes extra pile crown often in the concrete of the superfilled 0.5m-0.8m in top, and after concrete curing.
Summary of the invention
The object of the present invention is to provide one kind to abolish pile crown method, can efficiently abolish the superfilled concrete pile head in top, subtract
Few human cost, reduces difficulty of construction, improves construction efficiency.
To solve the above problems, abolishing pile crown method the present invention provides one kind includes: the first molding process of installation, filling
It starches region and the first mold is installed, and enter and install mold additional；Reinforcing bar step is installed, the first reinforcing bar is installed in first mold；
Second molding process is installed, the second mold is installed in first mold exterior, the lower part of second mold is recessed with one
Concave portion, the position that the recessed portion needs guiding through first reinforcing bar is provided with aperture, and the tapping is provided with rubber stopper,
And ensure will not spillage between first mold and second mold；Casing step is installed, second mold is being located at
Interior reinforcing bar is arranged with casing；Grouting step, to first mold and the second mold penetration concrete；Step of removal,
After concrete completes solidification, first mold and second mold are removed；Pile crown step is abolished, the recess is crushed
Concrete section；Pile crown step is removed, concrete at pile crown is hung.
After receiving in recessed portion, so that the first reinforcing bar is exposed herein, after concrete grouting, the first mold and second is removed
Mold, and the concrete at the second mold indentions portion is abolished, simultaneously because the reinforcing bar in the second mold is arranged with casing, so this
Place can hang top pile crown concrete.
Further, above-mentioned to abolish pile crown method further include: the first reinforcing bar step of adjustment is abolishing concrete at pile crown
Afterwards, by first bar straightening.
It is curved due to that may touch reinforcing bar in abolishing Concrete, so by reinforcing bar again straightening.
Further, above-mentioned to abolish pile crown method further include: the second reinforcing bar step of welding is wiped out in second mold
Reinforcing bar, and the second reinforcing bar is welded at first reinforcing bar place of wiping out.
If poured, effect is undesirable, and the reinforcing bar in the second mold, can be by recessed portion together with concrete bonding
Concrete is wiped out, and again welded reinforcement enter in next step pour.
Further, above-mentioned to abolish recessed portion described in pile crown method with a round-corner transition.
Further, above-mentioned to abolish the first mold described in pile crown method and second mold is made of plank.
Further, it is above-mentioned abolish the first molding process is installed described in pile crown method after, further includes: pre-buried step:
Second mold is laterally embedded with suspender steel pipe casing.
The present invention reduces difficulty of construction with that can reduce human cost, improves the technical effects such as construction efficiency.

Specific embodiment
In order to make the objectives, technical solutions and advantages of the present invention clearer, With reference to embodiment and join
According to attached drawing, the present invention is described in more detail.It should be understood that these descriptions are merely illustrative, and it is not intended to limit this hair
Bright range.In addition, in the following description, descriptions of well-known structures and technologies are omitted, to avoid this is unnecessarily obscured
The concept of invention.
In the description of the present invention, it should be noted that term " first ", " second ", " third " are used for description purposes only,
It is not understood to indicate or imply relative importance.
With reference to Fig. 1, illustrated embodiment of the present invention includes the following steps: to install the first molding process, installs in grouting region
First mold 1, and enter and install mold additional；Reinforcing bar step is installed, the first reinforcing bar 3 is installed in first mold 1；Installation second
Molding process, installs the second mold 2 outside first mold 1, and the lower part of second mold 2 has a recessed portion
21, the position that the recessed portion 21 needs guiding through first reinforcing bar is provided with aperture, and the tapping is provided with rubber stopper,
And ensure will not spillage between first mold 1 and second mold 2；Casing step is installed, second mould is being located at
Reinforcing bar in tool 2 is arranged with casing；Grouting step, to first mold 1 and 2 penetration concrete of the second mold；Demoulding
Step after concrete completes solidification, removes first mold 1 and second mold 2；Pile crown step is abolished, is crushed described
The concrete section of recess 21；Pile crown step is removed, concrete at pile crown is hung.
After receiving in recessed portion, so that the first reinforcing bar is exposed herein, after concrete grouting, the first mold and the second mould are removed
Tool, and the concrete at the second mold indentions portion is abolished, simultaneously because the reinforcing bar in the second mold is arranged with casing, so herein
Top pile crown concrete can be hung.
Simultaneously in order to avoid the concrete being located in the second mold 2 is Nian Jie with the first reinforcing bar 3, can be wrapped in jacket exterior
Foam, in this way at the top of removal when pile crown concrete, will not because the concrete in the second template 2 is Nian Jie with the first reinforcing bar 3 and
Cause top pile crown concrete that can not extract, so the amount of abolishing of concrete is greatly reduced.
Specifically, method shown in the present embodiment further include: adjustment 3 step of the first reinforcing bar is being abolished at pile crown after concrete,
By 3 straightening of the first reinforcing bar.
It is curved due to that may touch reinforcing bar in abolishing Concrete, so by reinforcing bar again straightening.
Specifically, method shown in the present embodiment further include: the second reinforcing bar step of welding is wiped out in second mold 2
First reinforcing bar 3, and the second reinforcing bar is welded at 3 place of wiping out of the first reinforcing bar.
If poured, effect is undesirable, and the reinforcing bar in the second mold, can be by recessed portion together with concrete bonding
Concrete is wiped out, and again welded reinforcement enter in next step pour.
Specifically, the recessed portion 21 in method shown in the present embodiment has a round-corner transition.
Specifically, first mold 1 in method shown in the present embodiment and second mold 2 are made of plank.
It, can also pre-buried two suspender steel pipes casing 22, reference in the first mold after the first molding process is installed
Steel wire is penetrated the through-hole formed by suspender steel pipe casing 22 in this way after completing concreting by Fig. 2 and Fig. 3, can be light
Pine completes lifting operation, removes pile crown.
It should be understood that above-mentioned specific embodiment of the invention is used only for exemplary illustration or explains of the invention
Principle, but not to limit the present invention.Therefore, that is done without departing from the spirit and scope of the present invention is any
Modification, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.In addition, appended claims purport of the present invention
Covering the whole variations fallen into attached claim scope and boundary or this range and the equivalent form on boundary and is repairing
