Description
Technical field
The utility model is related to a kind of reverse rotation drilling rods, are especially adapted for use in multiaxial type diaphram wall drilling machine, DCM
(DEEP CEMENT MIXING SYSTEM) processor and quiet brill take root in the underground foundations construction machinery such as drilling machine, belong to underground base
Plinth construction machinery technical field.
Background technology
Existing multiaxial type diaphram wall drilling machine, DCM processors and quiet brill take root in the underground foundations construction machine such as drilling machine
Tool, blade or stirring wing on every drilling rod are rotated toward a direction, and main deficiency is that mixing effect is relatively weak.It is existing
Technology up and down reciprocatingly stirs number to improve mixing effect by input compressed air or increase, but such processing method wastes
Energy consumption reduces construction efficiency.
Utility model content
The utility model is directed to the deficiencies in the prior art, has invented a kind of reverse rotation drilling rod, which is used for
The mixing effect between cement grout and soil can be improved after drilling machine, energy saving can consume, reduce the usage amount of cement
And construction efficiency can be improved.
To realize that the above goal of the invention, the utility model use following technical scheme：
A kind of reverse rotation drilling rod, including inner tube 1 and outer tube 2, one end of inner tube 1 is equipped with coupling 11, inner tube 1 it is another
End is equipped with nipple 12, and the axial arranged of inner tube 1 has upper impeller 13 and lower stirring wing 14, outer tube 2 to be equipped with stirring wing 21, outside
Pipe 2 and inner tube 1 are set with one heart, and outer tube 2 is also placed between upper impeller 13 axial arranged in inner tube 1 and lower stirring wing 14,
Inner tube 1 drives upper impeller 13 and lower stirring wing 14 to drive 21 concentric antiport of stirring wing with outer tube 2.
As a kind of preferable embodiment, axial arranged upper impeller 13 and lower stirring wing 14 and level in inner tube 1
The angle in face is more than 0 degree.
As another preferable embodiment, the angle of axial arranged stirring wing 21 and horizontal plane is more than 0 on outer tube 2
Degree.
As another preferable embodiment, in inner tube 1 axial arranged upper impeller 13 with it is axial arranged on outer tube 2
Stirring wing 21 it is oppositely oriented.
As another preferable embodiment, upper impeller 13, lower stirring wing 14 and outer tube 2 in inner tube 1 stir
It mixes the wing 21 and divides equally arrangement on respective same plane.
Description of the drawings
Attached drawing 1 is the front view for reversely rotating drilling rod, and attached drawing 2 is the vertical view for reversely rotating drilling rod.
Specific implementation mode
In attached drawing 1, attached reverse rotation drilling rod shown in Fig. 2, which includes inner tube 1 and outer tube 2.Inner tube
1 one end is equipped with coupling 11, and coupling 11 is six side's couplings or four key couplings, and the other end of inner tube 1 is equipped with nipple
12, form and size and the coupling 11 of nipple 12 match, and the core of inner tube 1 is equipped with slurry stream siphunculus；It is axial in inner tube 1
It is disposed with upper impeller 13 and lower stirring wing 14, and is more than 0 degree, generally 30 degree or so with the angle of horizontal plane.It is set on outer tube 2
There is stirring wing 21, and be more than 0 degree with the angle of horizontal plane, is generally also 30 degree or so.Stirring wing is at an angle to the horizontal surface,
Sweeping area when stirring wing rotation can be expanded, enhance mixing effect.Outer tube 2 and inner tube 1 are set with one heart, and outer tube 2 is also set
Between upper impeller 13 and lower stirring wing 14 axial arranged in inner tube 1, inner tube 1 drives upper impeller 13 and lower stirring wing 14
21 concentric antiport of stirring wing is driven with outer tube 2.The stirring of upper impeller 13, lower stirring wing 14 and outer tube 2 in inner tube 1
The wing 21 is divided equally on respective same plane to be arranged, circumferentially angle is 120 degree, and axial arranged upper in inner tube 1
The upper impeller 13 oppositely oriented such as axial arranged in inner tube 1 with stirring wing 21 axial arranged on outer tube 2 of stirring wing 13
To be left-handed, then stirring wing 21 axial arranged on outer tube 2 is dextrorotation；Similarly, if upper impeller 13 axial arranged in inner tube 1
For dextrorotation, then stirring wing 21 axial arranged on outer tube 2 is left-handed.The oppositely oriented stirring effect that can enhance stirring wing of the two
Fruit.
After this reverse rotation drilling rod is installed on the underground constructions machinery such as diaphram wall drilling machine or DCM processors, due to
Stirring wing and the oppositely oriented of the stirring wing on outer tube 2, operating in inner tube 1 is reversed also on the contrary, therefore cement can be substantially improved
Mixing effect between slurries and soil is made it stir evenly more abundant, the consumption of the consolidations such as cement is reduced with this, and
Energy consumption can be reduced, construction efficiency is improved.
