Common Accidents During The Construction Process of Rotary Drilling RIGS

Rotary drilling RIGS are widely used in engineering construction, but various accidents may also occur during the construction process. Understanding common accidents can help prevent them in advance and ensure construction safety. The following are six common types of accidents during the construction process of rotary drilling RIGS:

1. Hole wall collapse: Insufficient mud concentration or imbalance of water level inside the hole can easily cause hole wall collapse, which may lead to the drilling rig being buried, affecting the construction progress and increasing the treatment cost.

2. Buried and stuck drill: During drilling, if encountering a layer of shifting sand or improper operation, the drill tool may be seized by the sand and mud, which requires a lot of time and effort to retrieve and may even damage the equipment.

3. Main coil wire rope breakage: The wire rope may suddenly break due to long-term use wear or overload, causing the drill bit to fall, posing a safety hazard and delaying the project schedule.

4. Oil leakage from the power head: Aging of the sealing parts or improper installation can lead to oil leakage from the power head, which not only pollutes the construction site but may also cause equipment failure due to insufficient lubrication.

5. Pipe blockage: If the pipe is blocked during concrete pouring, it will interrupt the pouring process, which may cause quality problems such as broken piles and affect the load-bearing capacity of the pile foundation.

6. Equipment overturning: Poor site flatness or a shift in the center of gravity of the drilling rig may cause the entire machine to overturn, leading to serious safety accidents and threatening personnel lives and equipment safety.

Conclusion: Common accidents in the construction of rotary drilling RIGS are mostly related to equipment maintenance, operation norms and site conditions. Before construction, it is necessary to conduct thorough equipment inspection and site treatment. During construction, strictly follow the operating procedures and strengthen on-site monitoring. Only in this way can the risk of accidents be effectively reduced and the project be advanced safely and efficiently.
