Specific implementation mode
With reference to the accompanying drawings and examples, the specific implementation mode of the present invention is described in further detail.Implement below
Example is not limited to the scope of the present invention for illustrating the present invention.
Embodiment：A kind of cast-in-situ bored pile hole cleaning device, including drilling rod 1 are equipped at least one stirring on the drilling rod
Paddle 2, the agitating paddle are made of blade 3 and propeller hub 4, and the propeller hub encloses hoop on the drilling rod, the blade at least two panels
And blade face is fixed on upwards on the propeller hub.
The propeller hub is made of two valves, and one end of two valve propeller hubs is concave-convex type card slot 5, and the other end is to turn up in the axial direction
Butt strip 6, the radian of two valve propeller hubs it is equal and be less than 180 degree.
Agitating paddle is fixed on by the hoop effect of enclosing of two panels propeller hub on drilling rod.After stacks, agitating paddle is inserted in drilling rod,
Agitating paddle can be multiple, need to be arranged at a certain pitch on drilling rod according to construction, then the bolt passed through on butt strip fastens.
The internal diameter of the propeller hub is equal to the outer diameter of the drilling rod, and two valve propeller hubs are symmetrically set on the drilling rod, two valve paddles
One end of hub is connected by pin 7, and the other end is fastenedly connected by bolt 8.
The blade is two panels and is symmetrically distributed on the propeller hub that the blade face of the blade is in oblique helicoid.Agitating paddle
Two leaf paddles can be selected, paddle body material is steel, and two panels blade is symmetrically distributed on propeller hub circumference, and blade blade face is arranged upwards, with
Ensure that blade pushes mud upwards, blade root connect by welding with propeller hub；Propeller hub internal diameter can be equal to drilling rod outer diameter, but two valve propeller hubs
Radian be less than 180 degree, to ensure to have the space of fastening between two butt strips.
The concave-convex type card slot is equipped with vertically for the perforation of pin docking, and the butt strip is cut along circular arc
The through-hole fastened to direction for bolt.
The primary structure of the present invention is agitating paddle, and agitating paddle is made of blade, two valve propeller hubs, fastening bolt, pin.Blade
It is made by steel plate with propeller hub, blade is by being fixedly welded on propeller hub.Two valve propeller hub one end are connected by pin, and the other end is logical
Bolt is crossed to be fastenedly connected.
Propeller hub internal diameter can be equal to drilling rod outer diameter, but two valve propeller hubs should be less than 180 degree, to there is certain preload between butt strip
Space, the diameter that two panels blade is formed are less than bit diameter, to prevent agitating paddle to be damaged or rotate through during being sent under
Stake inner wall is damaged in journey；Hole-drilling pile-filling machine GPS-15 frequently with drilling rod outer diameter be 90mm, bit diameter is
800mm, the blade in embodiment can use 0.3mm steel plates to make, and propeller hub can use 0.5mm steel plates to make, and propeller hub internal diameter is 90mm, paddle
