Key Points of Rotary Drilling Rig Construction And Fault Handling

Rotary drilling RIGS play a crucial role in construction, but improper operation or equipment failure can easily affect the project progress. Mastering the key points of construction and the methods for handling faults can effectively enhance the efficiency and safety of operations. The following is a detailed introduction for you.

1. Pre-construction preparations: Before commencing work, a comprehensive inspection should be conducted to ensure that all components of the drilling rig are firmly connected, and that the hydraulic oil and lubricating oil are sufficient. At the same time, based on the geological investigation report, the drill bit and construction parameters should be reasonably selected to ensure that the equipment is in the best condition.

2. Drilling operation specifications: During drilling, the rotational speed and drilling pressure should be well controlled to avoid excessive speed and force, which may cause the hole wall to collapse. At the same time, pay close attention to the data on the dashboard, maintain the verticality of the hole positions, and prevent the occurrence of off-center holes.

3. Key points for handling construction waste: Timely clear the construction waste in the drill bucket to prevent overloading from affecting the drilling efficiency. For construction waste produced by different soil types, they should be classified and stacked for subsequent treatment to reduce pollution to the construction site.

4. Common faults: Insufficient power. If a decrease in the power of the drilling rig is found, it may be due to engine failure or leakage in the hydraulic system. First, check if the fuel and air filters are clogged, then investigate whether the hydraulic pipelines are leaking oil and repair them in time.

5. Common faults: Drill pipe jamming. During the drilling process, the drill pipe gets stuck, which may be due to encountering a hard object or the collapse of the hole wall. The drill pipe should be slowly reversed to try to get out of the predicament. If this is ineffective, some sand and soil need to be backfilled and the drilling Angle readjusted.

6. Equipment maintenance and care: After the construction is completed, the soil and oil stains on the drilling rig should be cleaned up in a timely manner, and the key parts should be lubricated and tightened regularly. Before long-term use, a comprehensive inspection of the equipment should be carried out and anti-rust and anti-corrosion measures should be taken.

Mastering the key points of construction and fault handling methods of rotary drilling RIGS is the foundation for ensuring the smooth progress of the project. Standardized operation can enhance construction efficiency, and timely troubleshooting can reduce losses from work stoppage. Only by attaching equal importance to construction and maintenance can the performance advantages of rotary drilling RIGS be fully exploited to ensure the smooth progress of engineering projects.
