Description
Technical field
The present invention relates to building bored concrete pile technology fields more particularly to one kind to take native Screw Pile drilling tool.
Background technique
Currently, common bored concrete pile broad categories, but two classes are basically divided into, i.e. straight rod type soil taking and filling pile and shaft
Screwed extrusion soil filling pile.It is both above to have shortcoming.For straight rod type soil taking and filling pile, the stake of smooth-sided compression candles
The bearing capacity that body provides is limited.It, then can only be by increasing pile body diameter and pile body length if facing higher bearing capacity demand
It realizes, a large amount of buildings and resources need to be consumed, and will cause unnecessary difficulty of construction；The screwed soil compaction of pile body is filled
For infusing stake, soil compaction negative effect will cause in formation of pile, if wanting, a spacing must be increased by reducing soil compaction negative effect, but and this
The reduction of Piling Density is so that foundation bearing capacity promotion is limited simultaneously, and extrusion soil filling pile is applied compared with soil taking and filling pile speed of application
Slowly, pile low efficiency.
Therefore, against the above deficiency, it is desirable to provide one kind takes native Screw Pile drilling tool.

Sea whelk is distributed in head, auger stem outer surface, and screw thread is distributed in drill bit outer surface, further includes the liquid driven by hydraulic power unit
Pressure stretch compression apparatus, movable thread are equipped with notch in the screw thread of the drill bit, the movable thread for making spiral shell are equipped in notch,
Hinged between movable thread and drill bit, movable thread is connect with hydraulic telescopic device, by hydraulic telescopic device driving activity thread
Horizontal direction closure or openness；The drill bit internal is double-layer structure, and the executive item of the hydraulic telescopic device is arranged described
In space clamped by double-layer structure.
Further, the movable thread is adapted with notch geometry, when movable thread is closed, outboard wheel profile and its institute
It is corresponding consistent in the helical trajectory of layer screw thread.
Further, in auger stem outer surface of upper at least a part of sea whelk outer diameter be greater than drill bit outer surface screw thread
Outer diameter.
Further, the length of the auger stem is more than or equal to the length of the drill bit.
Further, it the auger stem and the drill bit one-pass molding and is fixed together.
Further, the hydraulic power unit includes: control valve and connected pipes；The control valve is arranged in the spiral
At the top of drilling rod, the control valve is connect by connected pipes with the hydraulic telescopic device.
(3) beneficial effect
Above-mentioned technical proposal of the invention is had the advantages that cleverly compared with prior art using hydraulic telescopic device
Control activity thread automatically open and close, rotates in the forward direction and buries, rotate in the forward direction and mention, and realization takes soil, makes spiral shell, including outer diameter can
Change screw thread, fill concrete, at spiral shell, high at spiral shell quality, bearing capacity of single pile is high, and the drilling tool is using easy, speed of application is fast, construction quality
It is good, and environmental protection and energy saving, especially can with the size variation of manual control major diameter of thread, therefore, can be used for manufacturing high quality,
Major diameter of thread is alterable, the waney perfusion pile body of spiral shell diameter.
