Abstract
The utility model is related to Screw Pile technical field, more particularly to a kind of alloy bit.It is a kind of enter rock alloy bit, its technical scheme is：During stake machine drill has rock, six square joints are connected with stake driver drilling rod, transmission moment of torsion produces clockwise rotating force and provides plus-pressure downwards, bit matrix produces point hole by the continuous rock cutting of alloy block at its tip, aperture is expanded by both sides alloy block again, the helical tooth extruding soil of six square joint outer walls produces screw thread, after hole depth requirement is reached, stake driver drilling rod rotate counterclockwise transmits moment of torsion by six sides, simultaneously upward pile pulling power is provided by bearing pin, in the case of a speed and pitch relationship match are moved back in holding, mixed mud is pumped inward when moving back, filling speed is with moving back a speed Proper Match, complete formation of pile.The utility model can be smoothly completed to be in the milk into rock process and may realizing when moving back, and has a wide range of application, possesses the advantage for adapting to a variety of soil layers.
Description
Technical field
The utility model is related to Screw Pile technical field, more particularly to a kind of alloy bit.
Background technology
Cast-in-place Screw Pile is that have the rotary squeezing soil body using stake machine drill in work progress to be pumped concrete pile, pre- with driving into type
Stake processed is compared, and construction noise is low, without friction, on the stake constructed without influence；With full auger, the filling of conventional mud retaining wall pore-forming
Note stake is compared, mud-less pollution and spoir problem.But various complex situations, example occur in screw rod pile driving construction detailed process
The 30 meters of depths that drill such as are needed, the rock that one piece of area is more than drill bit cross-sectional area are but run into 20 meters of depth, existing drill bit was both
The rock can not be squeezed, can not also continue lower bore through the rock.
The content of the invention
The purpose of this utility model is：There is provided it is a kind of enter rock alloy bit, make Screw Pile disclosure satisfy that smoothly enter rock
Demand.
The technical solution of the utility model is：It is a kind of enter rock alloy bit, it includes：Interior six square joint, drill bit bottom
Seat, bit matrix and drill bit lid；
Interior six square joint is hollow structure, and its inwall is provided with hexagonal hole, and stake driver drilling rod is coordinated by bearing pin and hexagonal hole to be passed
Torque delivery, interior six square joints outer wall is provided with helical tooth；Interior six square joints inwall bottom is welded with sleeve pipe, the endoporus of interior six square joint
With sleeve pipe formation grouting channel；
Drill bit base is welded with interior six square joints outer wall lower end, and the outer wall of drill bit base is symmetrically provided with two arc openings
Groove；Dividing plate is provided between sleeve pipe and drill bit base inner wall；
Bit matrix and drill bit tube chamber welds with base, are provided with alloy block on the side face of bit matrix；
The drill bit side of covering center is provided with limited block, and drill bit lid is arranged on by axle at the arc opening groove of drill bit base.
During stake machine drill has rock, drill bit base both sides drill bit lid closure, six square joints are connected with stake driver drilling rod, are passed
Torque delivery produces clockwise rotating force and provides plus-pressure downwards, and bit matrix is constantly cut by the alloy block at its tip
Rock produce point hole, then by both sides alloy block expand aperture, six square joint outer walls helical tooth extruding soil produce screw thread, when up to
To after hole depth requirement, stake driver drilling rod rotate counterclockwise transmits moment of torsion by six sides, while upward pile pulling power is provided by bearing pin,
Holding moves back a speed with the case of pitch relationship match, pumping and being reached in mixed mud, mixed mud middle sleeve necessarily inward when moving back
Both sides drill bit lid can be pushed after height open under gravity, filling speed completes formation of pile with moving back a speed Proper Match.
Beneficial effect：The utility model can be smoothly completed to be in the milk into rock process and may realizing when moving back, and has a wide range of application,
Possesses the advantage for adapting to a variety of soil layers.The utility model can transmit more high pulling torque from six sides transmission moment of torsion and structure is reliable.
