Background technique
Armored concrete solid pile, section are generally square.Pile body section is generally long constant along stake.Solid square pile section ruler
Very little generally 200 × 200mm~600 × 600mm.The strength grade of concrete used in armored concrete solid pile is not preferably less than
C30(30N/mm2), the solid stake body length of armored concrete: it is limited to pile frame height, the length of in-situ precast stake is generally in 16m
Within.It is limited to traffic condition, prefabrication stake, stake is long to be usually no more than 16m, segmentation prefabricating is otherwise answered, then in piling process
In give spreading.Connector is no more than 3.The advantages of armored concrete solid pile: length and section can roots in a certain range
According to scene actual needs selection, due to prefabricated on the ground, production quality is easily guaranteed that, bearing capacity is high, and durability is good.Cause
This, using relatively wide in engineering.But after earth excavation, precast square pile needs manually abolish pile crown concrete, reserve reinforcing bar anchor
Enter in cushion cap or bottom plate, labour cost is high, and effect is low, has an effect on foundation construction progress.
Summary of the invention
Goal of the invention: present invention aims in view of the deficiencies of the prior art, provide one kind to exempt to cut pile crown type precast square pile
Constructing device and its construction method can be exempted to cut pile crown.
Technical solution: it is of the present invention exempt from cut a pile crown type precast square pile constructing device, including exempt from the prefabricated device mold of broken pile head,
Exempt from broken pile head Pile feeder, rubber gasket；The section for exempting from the prefabricated device mold of broken pile head be U-shaped square frame-shaped, cross-sectional width n with
The stake diameter of prefabricated pile is with width, and the prefabricated device die tip of broken pile head and the bottom end of exempting from is equipped with reinforcing bar fixation steel plate, the fixed steel of reinforcing bar
Plate is equipped with several through-holes and is used for fixed steel bars, and the rubber gasket is for wrapping up reinforcing bar and exempting from the prefabricated device mold of broken pile head
Formation separates；The broken pile head Pile feeder section of exempting from is square frame-shaped, and cross-sectional width m >=n+20mm is described to exempt from broken pile head Pile feeder
Inside is equipped with twice spacer.
Above-mentioned technical proposal is further improved, the wall thickness for exempting from the prefabricated device mold of broken pile head is 10mm, length is
800mm, distance is 30mm between through-hole on the steel plate, and the wall thickness for exempting from broken pile head Pile feeder is 30mm, and spacer wall thickness is
20mm。
Further, the rubber gasket is the tapered pad of 50mm thickness, diameter 30-50mm.
It carries out exempting to cut pile crown type precast square pile construction method using above-mentioned apparatus, include the following steps:
(1) after precast square pile carries out formwork, ties up reinforcing bar, in template end, the prefabricated device mold of broken pile head is exempted from installation, it is ensured that stake
Hold level with both hands whole closely knit, reinforcing bar is fixed using rubber gasket；
(2) precast square pile casting concrete demoulds after the molding of prefabricated pile crown, removes and exempt from the prefabricated device mold of broken pile head；
(3) it transports after prefabricated pile crown reaches intensity to designated place, exposed steel bar is protected；
(4) precast square pile displacement pile machine anchor ear is exempted from broken pile head Pile feeder in pile crown installation, exempts from broken pile head and send by Static pressure pile driver
Stake device is weldingly connected with former Pile feeder, and attention level when placement avoids discontinuity when piling that pile crown is caused to destroy
The utility model has the advantages that using device and method provided by the invention, by exempting from the prefabricated device mould of broken pile head at the top of prefabricated pile
Tool pours to form pile crown, and reinforcing bar is isolated by rubber gasket, carries out pile pressing protective by exempting from broken pile head Pile feeder, avoids brokenly
Except the process of pile crown, and the prefabricated pile of reserved steel bar is completed, has saved a large amount of time and human cost, improved efficiency,
Accelerate foundation construction progress.

Specific embodiment
Technical solution of the present invention is described in detail below by attached drawing, but protection scope of the present invention is not limited to
The embodiment.
Embodiment 1: exempt to cut pile crown type precast square pile constructing device as shown in Fig. 3 to Fig. 7, including exempt from the prefabricated device mould of broken pile head
Have, exempt from broken pile head Pile feeder and rubber gasket etc..Exempt from the prefabricated device mold of broken pile head using wall thickness 10mm, width n and prefabricated pile
Stake diameter is with width, and length 800mm, section is U-shaped, and in the through-hole of both ends steel plate setting diameter 30mm, for installing fixation
Reinforcing bar is used.Exempt from broken pile head Pile feeder using wall thickness 30mm, section is square frame-shaped, and box width m=n+20mm, inside is equipped with twice
The spacer of wall thickness 20mm.Rubber gasket thick, diameter 30-50mm tapered pad using 50mm, for wrapping up, reinforcing bar is same to exempt from broken pile
