Operation Steps:

A:When drilling starts working,reaming sleeve will open,borehole range will increase,which will casing shoe and casing tube.
B:When finish drilling in overburden layer,pay attention to reverse circulation,reaming sleeve circles up,eccentric drilling bit lifts out from the borehole.
C:The casing that can be left in the borehole to prevent borehole from collapsing while pulling out pipe and grouting concrete.
D:Regular drilling bits can be applied to drill the depth as required in the rock stratum.
