Furthermore, the top of the spiral squeezing and expanding drill bit is provided with a back pressure thread with the direction opposite to that of the thread at the bottom of the spiral squeezing and expanding drill bit.
The working principle is as follows:
the power head provides torque and axial pressure to drive the telescopic filling drill rod and the spiral squeezing and expanding drill bit to drill downwards, and the drill bit extrudes all soil in the pile hole into soil around the pile in the drilling process. After the pile is drilled to the designed depth, the drilling tool is lifted, the ground pump is started to continuously press and fill the filler into the extruded and expanded pile hole through the hollow channel of the drill rod and the drill bit filling channel, the filler pushes open a drill bit valve under the action of pressure and gravity to fill the pile hole, and finally the completely extruded and filled pile is formed. The telescopic drill rod can complete pile hole construction of different pile lengths according to engineering requirements, and the construction pile length is not limited by the height of the tower.
