What Do The Operators of Rotary Drilling RIGS Need To Learn

Rotary drilling RIGS are the "powerful tools" in pile foundation construction, and the professional ability of the operators is directly related to the construction efficiency and safety. To become a qualified rotary drilling rig operator, one needs to systematically study various knowledge and skills.

1. Equipment structure and principle: It is necessary to be familiar with the core components of the drilling rig such as the power head and hydraulic system, and understand the functions and interlocking mechanisms of each part. This is the foundation for precise operation. Only by understanding the structure can one predict the status of the equipment during operation and avoid blind operation.

2. Basic Operations and Parameter adjustment: One must master basic operations such as start-up and drill pipe lifting, and more importantly, learn to adjust parameters like rotational speed and pressure according to the geological conditions. For instance, the feed rate for clay layers should be slowed down, while for rock layers, the pressure should be increased to ensure stable drilling.

3. Geological identification and response: Be able to determine the geological type through the investigation report and the feel during drilling. Be vigilant against hole collapse when encountering sandy soil, and handle isolated rocks with caution. Targeted measures can effectively reduce problems such as stuck drills and buried drills.

4. Safety Regulations and Risk Control: It is essential to keep in mind the safety operation procedures. Before starting work, inspect the equipment and environment. During work, avoid risks such as high-voltage lines and soft foundations. In case of emergencies, one can stop the machine promptly to prevent the accident from escalating.

5. Simple maintenance and fault diagnosis: One should be proficient in daily maintenance, such as adding lubricating oil and cleaning drill bits. At the same time, one should be able to identify common faults, such as hydraulic oil leakage and circuit abnormalities, and provide timely feedback for repair to reduce downtime.

6.Construction collaboration and process control: It is necessary to cooperate with the surveyor to position the piles, connect the procedures with the steel cage team, and strictly control the depth and verticality of the holes in accordance with the construction specifications. Good collaboration can ensure seamless connection in the construction process.

In conclusion, the learning of rotary drilling rig operators is a combination of theory and practice. They need to have a solid knowledge reserve as well as flexible operation and adaptability. Only by constantly learning and improving can one play a key role in pile foundation construction and ensure the smooth progress of the project.
