Description
Technical field
The utility model is related to a kind of prefabricated pile body, more particularly to a kind of prefabricated plastic casing reinforced concrete stake, is applicable
Among the embankment stake civil engineering such as 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.
Certain application is obtained in base treatment engineering, 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), the construction method for preventing plastic sleeve concrete pile flexural deformation and its
Device (ZL201110004366.2), plastic casing concrete pile driving machine (ZL 200820170698.1), plastic bushing coagulation
The method (ZL 200910024639.2) of native stake and its reinforcing soft soil foundation, for freezing pore-creating cast-in-situ concrete-pile
The construction method (in examination as to substances, application number CN201510190787.7) of immersed tube and frost pore-creating cast-in-situ concrete-pile.The stake
Compared with the cast-in-place pile body of tradition, outside is provided with the plastic bushing of coarse shape to body, enhances the friction of pile body and surrounding soil
Effect, improves the bearing capacity of pile body.But the pile body there is also some shortcomings：1. plastic bushing exists for applying for pile body
Work increased certain difficulty, and speed of application is slow down to a certain extent；2. the pile body is Small Diameter Pile, and conventional is a diameter of
16cm or 20cm, and construction depth is in the range of 10~20m, causes the slenderness ratio of the pile body more than 50, highest can to 125,
There is buckling failure in such high-fineness ratio pile body, cause the bearing capacity of pile body to roll over to a certain extent under vertical load
Subtract；3. the pile body is plain concrete pile, and its bearing capacity is relatively low, therefore is applied in embankment engineering mainly as embankment stake, and
Industrial and civil architecture aspect there is no applies precedent；4. concrete should not fill closely knit in so elongated plastic bushing, and vibrate
Rod cannot be inserted into the bottom of so elongated plastic bushing；5. because the pile body is to set plastic bushing in advance, therefore plastics
The phenomenon that sleeve pipe can be racked under the active force of soil around pile, so as to seriously reduce its pile quality；6. due to the pile body
Slenderness ratio it is excessive, increased the quality testing difficulty of its pile, in engineering commonly use low strain dynamic dynamic monitoring be difficult to obtain
Good POP curve.However, one layer of plastic bushing is set on the outside of pile body has certain advantage, it is prevented from soil around pile pair
The erosion of pile concrete, particularly in the chlorine ion concentrations such as coastal waters, Binjiang environment higher, therefore this kind of road in area
The erosion of consideration pile foundation is needed in the engineerings such as dike, work China Democratic National Construction Association, extends the service life of pile foundation.Therefore, in order to overcome plastic bushing
The defect of concrete-pile and its scope of application of raising, need a kind of new pile mode of searching badly and both preserve plastic sleeve concrete pile
Advantage can expand its application prospect again and seem particularly significant.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of prefabricated plastic casing reinforced concrete
Stake.
The purpose of this utility model is achieved through the following technical solutions:This prefabricated plastic casing reinforced concrete
Stake, including：Plastic bushing, pile extension section, steel reinforcement cage, concrete and pile top；The pile extension section is constituted by connecing disk, connecing ring and connecing cap
, connect disk periphery and be uniformly arranged keyhole；The end of the steel reinforcement cage of bottom is connected with pile top；The plastic bushing is located at outermost
Side, bottom plastic bushing is connected with pile top by cementing agent；The end of steel reinforcement cage is provided with and connects ring, and the end for connecing ring is welded on and connects
On disk, the adjacent disk that connects is connected by connecing cap.
As preferred：The plastic bushing is double-walled plastic tubing.
The beneficial effects of the utility model are:
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), prefabricated plastic casing reinforced concrete stake can make Small Diameter Pile (d≤25cm), intermediate diameters stake (25cm<d<
80cm) with large diameter pile (d >=80cm), the slenderness ratio of pile body, and the arrangement of reinforcement in pile body are reduced, improve bearing capacity of pile foundation,
Embankment stake is can be not only used for, building pile foundation is can be used for again, increased its scope of application；
3), the pile quality of pile body is easy to detection；
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.

Footpath be 0.5m, thickness for 1cm connects disk 6, connect the mode according to Fig. 3 on disk 6, be uniformly arranged keyhole 9 on periphery, in order to connect cap
8 are spliced, and using steel pipe manufacturing length 0.3m, wall thickness 1cm, external diameter 0.45m's connects ring 7.
Successively make three sections of steel reinforcement cages 3, now first paragraph steel reinforcement cage 3 is welded with pile top 5, the other end with connect the phase of ring 7
Even, be then sleeved in first paragraph plastic bushing 1, plastic bushing 1 and pile top 5 use cementing agent are connected, treat it is cementing after the completion of,
To placing concrete 4 in plastic bushing 1, and vibratory compaction, maintenance shaping are carried out to concrete using vibrator；At the same time,
Second segment steel reinforcement cage 3 is enclosed within second segment plastic bushing 1, the two ends of steel reinforcement cage 3 each set and connect ring 7, and placing concrete 4 simultaneously shakes
It is close, the like, steel reinforcement cage 3 and plastic bushing 1 to the 3rd section are assembled, wherein one end of steel reinforcement cage 3 with connect the phase of ring 7
Connect, then placing concrete 4, vibratory compaction, maintenance shaping.
Finally, using will be provided with the end that connects ring 7, all welding connects disk 6 accordingly, as shown in Fig. 2 by connecing cap 8, general
Prefabricated section above-mentioned of three plastic bushing armored concrete are coupled together, and just form plastic bushing reinforced concrete pile.
As shown in figure 4, a number of stake top groove 11 and pile top groove 12 are made in place 10, by the modeling of length 3m or so
Material sleeve pipe 1 is vertically placed in stake top groove 11 and pile top groove 12, respectively as prefabricated section of pile body two ends, then as template
Fixed mount 14 is set around plastic bushing 1, to ensure not bend or mould during the casting concrete 4 in plastic bushing 1
Material sleeve pipe 1 jumps out stake top groove 11 and the outside of pile top groove 12 in pouring for concrete 4 under pressure is acted on；It is inserted into plastic bushing 1
Steel reinforcement cage 3, the overall diameter of steel reinforcement cage 3 is less than plastic bushing interior diameter about 3~6cm or so, then on the top of plastic bushing 1
Casting concrete 4, while vibrating head 13 is inserted into the concrete 4 that continuous vibratory compaction has been poured from the bottom up of plastic bushing 1,
Ensure pile quality；According to shown in Fig. 5, after the concrete 4 in plastic bushing 1 pour it is closely knit after, set at the top of steel reinforcement cage 3
Disk 6 is connect well and ring 7 is connect, the overall diameter for connecing ring 7 is equal with steel reinforcement cage 3, connected by welding procedure, connect the part inlay of ring 7 and exist
