Description
Technical field
The present invention relates to a kind of prefabricated pile body and preparation method thereof, particularly to a kind of prefabricated plastic casing reinforced concrete
Stake and its method for prefabricating are it is adaptable among the civil engineering such as embankment stake reinforcement system and building pile foundation.
Background technology
Currently, a kind of plastic casing on-site concrete pile is soft on highway, highway widening, railway, municipal administration, airport etc.
Base processes in engineering and obtains certain application, and Patents have:Plastic sleeve concrete pile (ZL 200920036795.6), list
The construction method (ZL 200610097347.8) of wall screw plastic casing on-site concrete pile, plastic sleeve concrete pile strength core
Hard and soft consubstantiality built pile (ZL 201120340788.2), prevent the diastrophic construction method of plastic sleeve concrete pile and its
Device (ZL 201110004366.2), plastic casing concrete pile driving machine (ZL 200820170698.1), plastic bushing mix
The method (ZL 200910024639.2) of the stake of solidifying soil and its reinforcing soft soil foundation, it is used for freezing pore-creating cast-in-situ concrete-pile
Immersed tube and frost pore-creating cast-in-situ concrete-pile construction method (in examination as to substances, application number CN201510190787.7).Should
Compared with the cast-in-place pile body of tradition, outside is provided with the plastic bushing of coarse shape to pile body, enhances rubbing of pile body and surrounding soil
Wiping acts on, and improves the bearing capacity of pile body.But this pile body there is also some shortcomings:1. plastic bushing exist for pile body
Construction increased certain difficulty, slow down speed of application to a certain extent;2. this pile body is Small Diameter Pile, conventional diameter
For 16cm or 20cm, and construction depth is in the range of 10~20m, and, more than 50, highest can be extremely for the slenderness ratio leading to this pile body
125, there is buckling failure in such high-fineness ratio pile body under vertical load, leads to the bearing capacity of pile body to have to a certain extent
Institute's reduction;3. this pile body is plain concrete pile, and its bearing capacity is relatively low, therefore applies in embankment engineering mainly as embankment stake,
And there is no application precedent in terms of industrial and civil architecture;4. concrete should not fill in so elongated plastic bushing closely knit, and
Vibrating spear cannot be inserted into the bottom of so elongated plastic bushing;5. because this pile body is to set plastic bushing in advance, therefore
The phenomenon that plastic bushing can rack under the active force of soil around pile, thus seriously reduce its pile quality;6. due to this
The slenderness ratio of pile body is excessive, increased the quality testing difficulty of its pile, and in engineering, conventional low strain dynamic dynamic monitoring is difficult to obtain
Obtain intact POP curve.However, arranging one layer of plastic bushing outside pile body have certain advantage, it is prevented from stake week
The erosion to pile concrete for the soil, particularly in the higher environment of the chlorine ion concentrations such as coastal waters, Binjiang, therefore this kind regional
Need in the engineerings such as embankment, work China Democratic National Construction Association to consider the erosion of pile foundation, extend the service life of pile foundation.Therefore, in order to overcome plastic sheath
The defect of pipe concrete stake and its scope of application of raising, need a kind of new pile mode of searching badly and had both preserved plastic bushing concrete
The advantage of stake can expand its application prospect again and seem particularly significant.
Content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, provide a kind of prefabricated plastic casing reinforced concrete stake and its
Method for prefabricating.
The purpose of the present invention is achieved through the following technical solutions:This prefabricated plastic casing reinforced concrete stake, bag
Include:Plastic bushing, pile extension section, steel reinforcement cage, concrete and pile top;Described pile extension section by flange, connect ring and connect cap and form, connect
Disk periphery is uniformly arranged keyhole;The end of the steel reinforcement cage of bottom is connected with pile top;Described plastic bushing located at outermost, under
End plastic bushing is connected by cementing agent with pile top;The end of steel reinforcement cage is provided with and connects ring, and the end connecing ring is welded on flange, phase
Adjacent flange is connected by connecing cap.
As preferred:Described plastic bushing is double-walled plastic tubing.
The method for prefabricating of this prefabricated plastic casing reinforced concrete stake, comprises the following steps:
1), stake top groove and pile top groove are set in the venue;
2), using plastic bushing as template, vertically it is placed in stake top groove and pile top groove;
3), fixed mount is set around plastic bushing, and is inserted into steel reinforcement cage in plastic bushing;
4), in plastic bushing top casting concrete, vibrating head is inserted into the closely knit pile of plastic bushing internal vibration simultaneously;
5), set flange at top and connect ring, then by the prefabricated section of maintenance molding at pile body two ends;
6), the vibration table consistent with unit pile body length is set in the venue;
7), plastic bushing two ends are respectively opened up a charging aperture and a gas outlet, and using this plastic bushing as template,
Laterally disposed on a vibration table, laterally inserted steel reinforcement cage in plastic bushing simultaneously, and expose plastic bushing certain length;
8), blind end is set at plastic bushing two ends, then passes through charging aperture casting concrete, treat that there is concrete gas outlet
During spilling, stop pouring;
9), set flange at two ends and connect ring, then by prefabricated section of maintenance molding in the middle of pile body, finally remove closing
End;
10), lift prefabricated section of pile body two ends and prefabricated section of pile body centre, accurately on the flange of each prefabricated section of docking
Each prefabricated section is finally connected as a single entity using connecing cap by keyhole, forms prefabricated plastic casing reinforced concrete stake.
The invention has the beneficial effects as follows:
1), the stake of prefabricated plastic casing reinforced concrete substitute cast-in-place plastic sleeve concrete pile improve speed of application,
Pile quality and bearing capacity;
2), the stake of prefabricated plastic casing reinforced concrete can make Small Diameter Pile (d≤25cm), intermediate diameters stake (25cm<d<
80cm) with large diameter pile (d >=80cm), reduce the slenderness ratio of pile body, and arrangement of reinforcement in pile body, improve bearing capacity of pile foundation,
Can be not only used for embankment stake, can be used for building pile foundation again, increased its scope of application;
3), the pile quality of pile body is easy to detect;
4), for steel reinforcement cage, then without having to worry about thickness of concrete cover problem, it is applicable to the stronger sea of aggressivity
In the environment such as ocean, coastal waters and Binjiang.
