A, use

Long spiral drill is widely used in high-rise buildings, urban traffic construction of pile foundation of construction of the project. Mainly used in the loose soil, sandy soil layer, the sandy soil layer and a small particles with small gravel layers. Main operation applicable methods are:

1, do homework method: after a hole withdrawing bit, shift, put reinforcing cage, pouring concrete.

2, CFG method: drill to stop drilling after the design elevation, from the power plant and drilling tools pouring concrete withdrawing bit edge center side note concrete to design elevation.

3, DDC method: after a hole drilling, and shift put to hole in the rubble, rubble hpa etc and clay, lime and solidify the mixture of heavy hammer to design elevation.

4, grouting replacement method: to design elevation drilling, after withdrawing bit edge from the power plant and drilling tools center to hole injection water mud, to design elevation, remove drilling reinforcing cage again and invest in sand, stone into piles.

5, once a pile law: drill to design elevation stop after the drilling, drilling edge to edge mention hole into the concrete to design elevation, remove the rig, to insert hole reinforcing cage into piles.

Second, the characteristics

With low noise, small vibration, torque, multi-function, into holes speed, filling pile drilling can be synchronism finish, flexible, construction efficiency etc.
