双层筒钻E

小筒体先行切入，大筒钻跟进环切释放岩石围压；

截齿阶跃破碎兼研磨钻进 ;

小钻具取芯率高，大钻具分级配合破碎 ;

适用地层：碎石土，卵石层，中风化岩层；

1.The inner shell starts drilling first, the outer shell follows.

2.The cutting rings are attached with 21-70 rock drilling bits, this design releases the internal stress of rock.

3.These rock drilling bits perform stage breaking and foundation drilling.

4.The small inner core barrel facilitates the coring operation, the large outer barrel performs stage breaking.
