Since 2003, the rotary drilling rig has risen rapidly in the domestic and international markets, and has occupied a stable position in the pile industry. As a new investment method, many people have followed the practice of rotary drilling rig, and the operator has become a very popular high paid occupation. The large output of rotary drilling rigs requires a lot of operators. What basic professional qualities should rotary drilling rig operators have?
A. About construction method
When the rotary drilling rig is used for geological grouting in the thick mud layer, it may have the problem of overbalance. There are mudstones underneath, which are slippery and hard. This requires the operator to have a certain construction ability. The mud layer requires the drilling machine to rotate at a high speed without pressurization and to move slowly to solve the problem of excessive square footage. The main reason for the difficulty in footage is the improvement of drilling tools, and more importantly, how to select drill bits.
B. Ability to maintain and repair rotary drilling rigs
As a rotary drilling rig operator, it does not mean that you are qualified to operate the drilling rig well. It is also necessary to go to the rig to maintain and inspect the rig in person. Only in this way can the problem be found and the accident handled in the bud.
For example, there is an operator who will not even add the oil of the rotary drilling rig, and let the auxiliary workers do it. The assistant just added lubricating oil to complete the task, and did not check carefully, and did not find that the screw of the lifter (rotary joint) was loose, so he lowered the power head. More than an hour after the start of construction, because the bolt fell into the drill pipe, there was a rod phenomenon, and there was a fault that the drill bit could not lift the hole. If the operator found out early and dealt with it early, things would not be so complicated, so the operator must go to maintain and inspect the drilling rig in person.
C. The skill level of the operator can directly see the interpretation of various geology and work efficiency
For example, some operators will prefer KBF (pick sand drill) and KR-R (commonly known as barrel drill, core drill) when they encounter the geology where the compressive strength of underground weathered rock is 50Kpa, rather than SBF (spiral drill bit), because the depth of the hole is more than 35 meters, many drill rig operators cannot unlock the lock of the machine lock rod, which causes the drill rod to fall when the drill rig lifts the drill. But what they don’t know is that in this geological situation, the SBF (spiral drill bit) is very superior in both structure and crushing effect. If the inclined hole can be found and the deviation can be corrected in time, the drilling effect is very good.
