Lean on, but bored concrete pile is in boring drilling process, each owing to rig out-of-flatness in place or drilling process being encountered soil layer change etc.
Plant different factors, cause pore-forming inclination, the phenomenon of off normal to happen occasionally, affect the construction quality of cast-in-situ bored pile.
Utility model content
Utility model purpose: provide a kind of drilling pile drill with high verticality, it is possible to prevent pore-forming and incline
Tiltedly, the phenomenon of off normal.
Technical scheme: double belt drilling pile drills with high verticality described in the utility model, including drilling rod,
Lower location annulus and upper location annulus；The annulus external diameter of lower location annulus and upper location annulus is equal, and passes through vertical supporting
Bar is vertically connected with composition tubbiness framework drill bit；Drilling rod is arranged on the centrage of tubbiness framework drill bit by transverse support bar, and
The two ends of drilling rod are stretched out from the two ends up and down of tubbiness framework drill bit；It is tiltedly installed with between the lower end of drilling rod and lower location annulus
Cutting knife bar；Drilling rod is tiltedly installed with propelling movement impeller；Drilling rod and on position between annulus and be provided with brace.
Use lower location annulus and upper location annulus to constitute the tubbiness framework drill bit of double waistband type, thus effectively guarantee
The perpendicularity of drill bit construction, prevents pore-forming inclination, the phenomenon of off normal；When using cutting knife bar can either meet brill under drill bit
Split requirement, can effectively strengthen again the structural strength of drill bit entirety lower end；Use and push impeller and can be easy to get out
Mud is delivered up；Brace is used can effectively to strengthen the structural strength of upper location annulus.
As further restriction scheme of the present utility model, it is provided with mounting flange in the upper end of drilling rod, on mounting flange
It is provided with alignment pin；It is provided with conical head in the lower end of drilling rod.Use mounting flange can facilitate the detachable installation of drill bit, simultaneously fixed
Position pin can effectively strengthen the steadiness of installation.
As further restriction scheme of the present utility model, lower location annulus is that cross props up by four transverse support bar
Support is on drilling rod；Upper location annulus is that cross is supported on drilling rod by four transverse support bar.Use cross hang mode
Can effectively strengthen drilling rod and lower location annulus and the steadiness of upper setting circle ring structure, annulus is askew to prevent life-time service from occurring
Oblique problem.
Compared with prior art, it provides the benefit that this utility model: (1) uses lower location annulus and upper location annulus structure
Become the tubbiness framework drill bit of double waistband type, thus effectively guarantee the perpendicularity that drill bit is constructed, prevent pore-forming and tilt, partially
The phenomenon of position；(2) use cutting knife bar can either meet split requirement when boring under drill bit, can effectively strengthen again drill bit overall
The structural strength of lower end；(3) propelling movement impeller is used can be easy to be delivered up the mud got out；(4) employing brace can
Effectively strengthen the upper structural strength positioning annulus.

Detailed description of the invention
Below in conjunction with the accompanying drawings technical solutions of the utility model are described in detail, but protection domain of the present utility model
It is not limited to described embodiment.
Embodiment 1:
As illustrated in fig. 1 and 2, double belt drilling pile drills with high verticality of the present utility model include: drilling rod
1, lower location annulus 2 and upper location annulus 3.
Wherein, the annulus external diameter of lower location annulus 2 and upper location annulus 3 is equal, and is vertically connected with by vertical supporting bar 4
Constitute tubbiness framework drill bit；Drilling rod 1 is arranged on the centrage of tubbiness framework drill bit by transverse support bar 6, and the two of drilling rod 1
End stretches out from the two ends up and down of tubbiness framework drill bit；It is tiltedly installed with cutter between the lower end of drilling rod 1 and lower location annulus 2
Bar 5；Drilling rod 1 is tiltedly installed with the propelling movement impeller 11 pushing the mud got out；Drilling rod 1 and on position between annulus 3 and set
There is brace 10；It is provided with mounting flange 7 in the upper end of drilling rod 1, mounting flange 7 is provided with alignment pin 12；Lower end at drilling rod 1
It is provided with conical head 8；Lower location annulus 2 is supported on drilling rod 1 in cross by four transverse support bar 6；Upper location annulus 3 leads to
Cross four transverse support bar 6 to be supported on drilling rod 1 in cross.
Of the present utility model have double belt drilling pile drills of high verticality when making, and needs at conventional bit
On the basis of, drilling rod 1 is lengthened, then be welded with on the drilling rod 1 after lengthening an equal amount of lower location annulus 2 and on position annulus
3, then by being welded to each other connection by vertical supporting bar 4 between lower location annulus 2 and upper location annulus 3, thus become one
The tubbiness framework drill bit of approximation tubbiness, lower location annulus 2 and upper location annulus 3 all use steel pipe cutting to form, to soft layer
Or the soil layer under different geological conditions holes and ensure that the perpendicularity of boring, effect is fine.
Of the present utility model have double belt drilling pile drills of high verticality when installing and using, and needs by peace
Dress flange 7 is connected with the drive rod on top, and is fixed installation by installing hole 9, it is ensured that drill bit does not rocks when using,
Positioning action due to conical head 8 so that drill bit location rapidly, and in going down process due to lower location annulus 2 and on position
Annulus 3 constitutes the tubbiness framework drill bit of double waistband type so that drill bit construction has preferable perpendicularity, effectively prevents
Pore-forming tilts, the phenomenon of off normal.
Although as it has been described above, represented and described this utility model with reference to specific preferred embodiment, but it must not
It is construed to the restriction to this utility model self.In the spirit and scope of the present utility model defined without departing from claims
Under premise, can various changes can be made in the form and details to it.
