To achieve the above object, the technical solution adopted in the utility model is as follows：
A kind of pile foundation pile crown auxiliary cuts device, including PVC sleeve pipes and reinforcing bar suspension ring, and described PVC casing inner diameters are more than
The external diameter of steel reinforcement cage cage bar, and the number of PVC sleeve pipes is not less than the number of steel reinforcement cage cage bar, the length of PVC sleeve pipes is not less than stake
The height of foundation pile head；Described reinforcing bar suspension ring have multiple, and two neighboring reinforcing bar suspension ring are connected using steel wire rope；Also include closure
Layer, bottom of the described plugged zone in PVC sleeve pipes.
It is further preferred that the length of described PVC sleeve pipes is highly bigger 10~20cm than pile foundation pile crown.
It is further preferred that a diameter of 100mm of described PVC sleeve pipes
It is further preferred that the material of described plugged zone is adhesive tape, waste and old gunnysack, polybag or bag of cement.
It is further preferred that described reinforcing bar suspension ring have two.
It is further preferred that described reinforcing bar suspension ring are made up of a diameter of 12mm of use HRB400 reinforcing bars.
Compared with prior art, its advantage is the utility model：
The utility model pile foundation pile crown aids in the use for cutting device to reduce artificial chisel and removes pile foundation steel bar cage cage bar periphery
Concrete link, improves efficiency of construction, while reduces and break after bar bending cage cage bar straightening link again, accelerates construction speed,
The duration is saved, there is great use value.

Embodiment
The utility model is described in further detail with reference to embodiment.
It will be understood to those of skill in the art that the following example is merely to illustrate the utility model, and should not be regarded as limiting
The scope of the utility model.Unreceipted particular technique, annexation or condition person in embodiment, according to document institute in the art
The technology of description, annexation, condition are carried out according to product description.Material therefor, instrument or the unreceipted production of equipment
Manufacturer person, being can be by buying the conventional products obtained.
As shown in Fig. 4~Fig. 6, a kind of pile foundation pile crown auxiliary cuts device, including PVC sleeve pipes 7 and reinforcing bar suspension ring 8, described
The internal diameter of PVC sleeve pipes 7 be more than steel reinforcement cage cage bar 2 external diameter, preferably PVC sleeve pipes 7 a diameter of 100mm, and PVC sleeve pipes 7
Number is not less than the number of steel reinforcement cage cage bar 2, and the length of PVC sleeve pipes 7 is not less than the height of pile foundation pile crown, preferably described PVC sets
The length of pipe 7 is highly bigger 10~20cm than pile foundation pile crown；Described reinforcing bar suspension ring 8 have it is multiple, preferably two, and two neighboring
The use steel wire rope 9 of reinforcing bar suspension ring 8 is connected, and preferably described reinforcing bar suspension ring 8 are made up of a diameter of 12mm of use HRB400 reinforcing bars.
Also include plugged zone 10, bottom of the described plugged zone 10 in PVC sleeve pipes 7.It is preferred that the material of plugged zone 10 is adhesive tape, given up
Used Gunny Bag, polybag or bag of cement.
It is the PVC sleeve pipes of Φ 100, the reinforcing bar suspension ring of HRB400 Φ 12 that pile foundation pile crown auxiliary of the present utility model, which cuts device,
The simple and practical construction auxiliary device of construction is cut for pile crown, its construction method is as follows：
The pile foundation pile crown for needing to cut is calculated according to this engineering stake top design altitude pile foundation perfusion depth displacement actual with scene
Length, the length of PVC sleeve pipes suitably lengthens 10~20cm according to pile foundation pile crown length, in pile foundation filling concrete to design of pile top
