Product Description
Casing System, also named Eccentric Casing System, is suitable for drilling water wells, geothermal wells, short mircopiles,medium mini-type grouting hole of building, diamond harbour project.
Economy: Eccentric is the most economical solutions because its ingenious reaming wing the bit is retrievable can be used at the next hole.
Working Principle:
When drilling, the reamer bit will rotate out to enlarge the hole which enough for the casing tube slide down behind the reamer. When reached required depth, the drill pipe will drill to the reverse direction and the reamer bit will retract, It is allowing the whole drilling system to pass through the casing.
working principle:
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.
