Valency is high, speed of application is slow, and mud is big for environment pollution.
The content of the invention
Hole-forming device and its forming hole method are combined with inside spin it is an object of the present invention to provide a kind of concrete-pile external spiral, is led to
Cross and set up external spiral blade steel sleeve, pore-forming is combined with inside spin using external spiral, both improve pore-forming efficiency, lift hole quality
And security, while avoiding pollution of the conventional forming hole method to environment.
To achieve these goals, the present invention is adopted the following technical scheme that：
A kind of concrete-pile external spiral combines hole-forming device, including screw shell 1, auger stem 2, drill bit 3 and brill with inside spin
Head protection covers 4, and its feature is：Auger stem 2 is set in screw shell 1, gap is left therebetween；The lower end of auger stem 2
Head is provided with drill bit 3；Drill bit protective case 4 is hollow steel bushing, and its diameter of bore is more than the outside diameter of drill bit 3, is located at auger
Bar 2 has at the lower end of drill bit 3, is welded to connect with auger stem 2 by Steel bar rack.
Its feature is also resided in：
Described screw shell 1 is welded with helical blade and is made in the cylindrical of large diameter steel pipe, and helical blade is helically
Type, helical blade is 10 ° to 30 ° with horizontal plane angle.
Described auger stem 2 is welded with helical blade and is made in the cylindrical of steel pipe, helical blade helically type,
Helical blade is 10 ° to 30 ° with horizontal plane angle.
Described screw shell 1 and the material of the helical blade of auger stem 2 are steel alloy, the thickness of helical blade for 4-
20mm。
A kind of concrete-pile external spiral combines the forming hole method of hole-forming device with inside spin, and its feature is to include following step
Suddenly：
a：After the positioning of stake position, screw shell 1 enters Rock And Soil, internal helicoid drilling rod 2, the and of drill bit 3 using clock wise spirals mode
Drill bit protective case 4 carries out Rock And Soil using counter-clockwise helical mode, and be automatically drained out for soil body extruding by helical blade；
B. after stake position hole depth reaches predetermined absolute altitude, borehole cleaning, pile cast is carried out or prefabricated pile is put into.
Beneficial effects of the present invention：
Due to being additionally arranged external spiral sleeve pipe, external spiral sleeve pipe and inside spin drilling rod, drill bit rotate and excavate the soil body simultaneously during pore-forming, carry
Pore-forming efficiency high, improves hole quality and security；Because be automatically drained out for soil body extruding by helical blade, while avoiding
Pollution of the conventional forming hole method to environment.
