A kind of bull deep-layer stirring device
Technical field
The utility model relates to the realm of building construction, particularly relates to the mixing plant in a kind of cement-soil stirring pile construction technology.
Background technology
Along with the utilization of deep-mixed pile (wall) technology, the research and development of deep-mixing pile driver also deepen continuously, and new stake machine and construction technology continue to bring out.As everyone knows, at present mixing pile machine commonly used is to adopt (or many) drilling rod to drive (or a plurality of) drill bit to stir construction while creeping into, and its formed pile body has the characteristics such as globality, water stability are good.Its weak point is: its formed pile body is the solid pile cylinder, when cement-soil retaining wall pouring pile hole, can get the core soil-cement body because of pouring pile hole, greatly waste cement consumption, increase engineering and drop into, high than undisturbed soil because of soil cement intensity simultaneously, increase the pore-forming difficulty.
The utility model content
For addressing the above problem, the utility model provides a kind of bull deep mixer that can effectively save the pile body construction material.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of bull deep-layer stirring device, it is characterized in that: comprise the mixer support body and be installed on the interior unit head of mixer support body, link to each other with the clutch end of unit head and to be provided with rotating disk, link to each other with rotating disk and to be provided with some drilling rods, each drilling rod be distributed in rotating disk around, the bottom of each drilling rod all is equipped with stirring-head.
Be further used as the improvement of technical solutions of the utility model, the equal diameters of each stirring-head.
Be further used as the improvement of technical solutions of the utility model, the diameter of stirring-head is less than each place, drilling rod axle center diameter of a circle.
Be further used as the improvement of technical solutions of the utility model, be provided with the connector that two ends all fix with drilling rod between two adjacent drilling rods, the below of mixer support body is provided with the rotating disk that all links to each other with each drilling rod.
Be further used as the improvement of technical solutions of the utility model, the top of each drilling rod is equipped with stock inlet.
Be further used as the improvement of technical solutions of the utility model, the diameter of stirring-head is not less than 100mm.
The beneficial effects of the utility model: the output of this bull deep-layer stirring device unit head when carrying out mixing pile construction drives turntable rotation, while driven by rotary disc drilling rod and the stirring-head that is installed on the drilling rod are whitewashed around a cement mixing method design stake circle of position center edge boring limit, thereby form the cylindrical shape stake, can effectively save pile body middle part construction material, reducing construction cost.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the apparatus structure schematic diagram of bull deep-layer stirring device in the utility model;
Fig. 2 is the utility model drilling rod position schematic cross-section.
The specific embodiment
With reference to Fig. 1~Fig. 2, the utility model is a kind of bull deep-layer stirring device, comprise mixer support body 1 and be installed on unit head 2 in the mixer support body 1, link to each other with the clutch end of unit head 2 and to be provided with rotating disk 4, link to each other with rotating disk 4 and to be provided with some drilling rods 3, each drilling rod 3 be distributed in rotating disk 4 around, the bottom of each drilling rod 3 all is equipped with stirring-head 5.
The output of this bull deep-layer stirring device unit head 2 when carrying out mixing pile construction drives rotating disk 4 rotations, while rotating disk 4 drive drilling rods 3 and the stirring-head 5 that is installed on the drilling rod 3 are whitewashed around a cement mixing method design stake circle of position center edge boring limit, thereby form the cylindrical shape stake, can effectively save pile body middle part construction material, reducing construction cost.
The quantity of drilling rod 3 can arrange according to the construction needs, becomes the set-up mode of centrosymmetric a plurality of drilling rod 3 around the power output shaft axle center of unit head 2, all in protection domain of the present utility model.
As the utility model preferred embodiment, the equal diameters of each stirring-head 5.
As the utility model preferred embodiment, all on the circumference of a rotating disk 4, the diameter of stirring-head 5 is less than each place, drilling rod 3 axle center diameter of a circle in the axle center of each drilling rod 3.
As the utility model preferred embodiment, two 3 adjacent on drilling rods are provided with the connector 6 that two ends all fix with drilling rod 3, and the below of mixer support body 1 is provided with the rotating disk 4 that all links to each other with each drilling rod 3.
Connector 6 is connected in 3 on adjacent in twos drilling rod, can strengthen the rigidity of each drilling rod 3, makes things convenient for its drilling construction, and the center of rotating disk 4 connects the axle output of unit head 2, pivots to drive each drilling rod 3.
As the utility model preferred embodiment, the top of each drilling rod 3 is equipped with stock inlet 7.
As the utility model preferred embodiment, the diameter of stirring-head 5 is not less than 100mm.
This mixer passes through stock inlet 7 to each drilling rod 3 interior slip casting, each stirring-head 5 whitewashing while holing that distributes around the unit head 2, thus form the cylindrical shape stake, wherein, the wall thickness of cylindrical shape stake namely equals the diameter of stirring-head 5.
Change the distance between the axial line distance unit head 2 output shaft axis of drilling rod 3 in this bull deep-layer stirring device, the cylindrical shape stake of the different outer circumference diameter sizes of can constructing, and after changing the size of stirring-head 5 in this bull deep-layer stirring device, the cylindrical shape stake of the different wall of can constructing degree.
Certainly, the utility model is created and is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of the utility model spirit, the modification that these are equal to or replacement all are included in the application's claim limited range.
