How To Improve The Construction Efficiency of Rotary Drilling RIGS？

As a core equipment in foundation engineering, the construction efficiency of rotary drilling RIGS directly affects the project schedule and cost control. In actual operations, efficiency improvement does not solely rely on equipment power but requires scientific coordination from multiple dimensions such as equipment management, operation norms, and environmental adaptation. The following is a detailed explanation from six key dimensions.

1. Conduct thorough preoperative inspection and maintenance of equipment: Before operation, check the wear degree of the drill pipe, the pressure of the hydraulic system and the fuel level one by one to avoid interruption of construction due to component failure. Regularly replacing the filter element and lubricating oil as per the instructions can reduce the probability of sudden shutdown by more than 30%.

2. Reasonably match drilling tools with geological conditions: For clayey soil, use spiral drill buckets; for sand and gravel layers, switch to sand-picking drill buckets. Unsuitable drilling tools can reduce the drilling speed by 50%. The diameter of the drilling tool should be precisely matched with the designed size of the pile hole to reduce the time for reaming or repairing the hole in the later stage.

3. Optimize the setting of drilling parameters: Adjust the drilling pressure and rotational speed according to the geological hardness. For soft soil layers, the rotational speed can be appropriately increased, while for hard rock layers, the pressure needs to be increased to protect the drill teeth. Control the lifting speed of the drill bucket to prevent the spillage of debris or the shaking of the drill pipe due to excessive speed.

4. Standardize operation procedures to reduce errors: Operators must strictly follow the principle of "slow drilling, steady drilling, and gentle lifting" to avoid blind pressurization causing the drill pipe to bend. After each drilling, the debris in the drill bucket should be cleared in time to prevent the residual soil from affecting the efficiency of the next round of drilling.

5. Scientifically plan the layout of the construction site: Set the mud pit and the soil storage area within the operating radius of the drilling rig to reduce the round-trip transportation time of the drill bucket. Rationally plan the construction sequence of pile positions to avoid mutual interference during the construction of adjacent pile holes and improve the utilization rate of the site.

6. Strengthen the collaboration and coordination among construction personnel: The drilling rig driver and the ground command should maintain real-time communication to clearly understand the drilling depth and stop drilling signals. Assign dedicated personnel to be responsible for the removal of construction waste and the replacement of drilling tools, achieving a seamless connection of "drilling - debris removal - drill replacement", and reducing the idle time of equipment.

In conclusion, enhancing the construction efficiency of rotary drilling RIGS is a systematic project, which requires integrating equipment maintenance, technical adaptation, and personnel collaboration throughout the entire construction process. Through scientific management and standardized operation, not only can the efficiency of single-machine operation be enhanced, but also a solid guarantee can be provided for the overall progress control of the project. Especially in the basic projects with tight schedules, these measures can better highlight their economic and time value.
