Once bore a hole in the unstable soil formation, there is potential risk of hole collapsing. Casing drilling is an ideal drilling method that combine the drilling and casing process together to stabilize the hole. Powered by DTH hammer, the casing system has a pilot bit which drives a ring bit to drill a hole wide enough so that a casing tube can slide down to the hole. As the drilling process and casing process are performing at the same time, the casing tube can stabilize the hole immediately.
Overburden casing drilling system can be classified into concentric casing system, eccentric casing system and slide block casing system. Eccentric casing system is the most economical drilling solution because its reamer bits can be retrievable and can be used to drill next hole. It is ideal to drill shallow holes in well drilling and micro piling work. Eccentric overburden casing system is composed of a pilot bit, reamer bit, guide device and casing shoe.
How does Eccentric casing system(ODEX) work?
1. Once drilling starts, the reamer bit will rotate out to enlarge the hole wide enough so the casing tube can slide down smoothly behind the reamer
2.After drilling into the required depth, rotation is reversed to retract the reamer bits so the whole drilling system can be pulled out through the casing tube.
