Construction, and ground source heat pump hole construction, and take into account the construction of small foundation pile holes, hydrological well holes and blast holes.

Main feature

1.It has no dull pollution and no need air compressor when drill the incompact ground area,the gravel place and fragment rock stratum.

2.Special tube drilling technical,it can drilling fast and insure projects firmly.

3.In complex condition,it can use double tube rotating drilling,in order to make hole stable and easy to slip casting.

4.The drilling rig can be spplied for different technique methods and a variety of ground conditions.Especially in the different work condition,such as the incompact ground area,the gravel place,and the fragment rock stratume,this drilling can always provide the operator excellent solutions.

5.The speed of borehole is faster than traditional machine.

6.It has adopted top haydraulic rotart power head impact which is Germany imported,multi drilling, and excellence performance.
