A Summary of The Key Points of Rotary Drilling Rig Construction

In the field of construction, rotary drilling RIGS are widely used due to their advantages such as high efficiency and environmental friendliness. The construction process needs to precisely control the key links to ensure the quality and safety of the project. The following is a summary of the six key points of rotary drilling rig operation:

1.Site leveling and layout: Before construction, it is necessary to ensure that the site is flat and solid to prevent the drilling rig from tilting. Based on the design drawings, precisely set out the lines and positions, determine the center of the pile positions, make marks and recheck them to lay a foundation for the subsequent construction.

2. Drilling rig installation and commissioning: The drilling rig must be installed stably and reliably, and check whether all components are operating normally. Debug the drill bit, hoist and other devices to ensure that parameters such as drilling depth and verticality meet the design requirements, and guarantee the construction efficiency.

3. Mud preparation and management: Mix mud reasonably, control its density and viscosity to stabilize the hole wall and suspend drill cuttings. During construction, the performance of the slurry should be monitored in real time, and the slag should be cleared and the slurry replenished in a timely manner to prevent accidents such as hole collapse.

4. Drilling process control: During drilling, the speed should be uniform and slow, and the rotational speed and drilling pressure should be adjusted according to the soil layer. Closely observe the data on the instrument panel, record the drilling depth and abnormal conditions, and ensure that the hole formation quality meets the specification standards.

5. Lowering the steel cage and pouring concrete: The steel cage must be inspected and accepted as qualified before being lowered to ensure its accurate position. Concrete pouring should be carried out continuously. The pouring speed and the burial depth of the conduit should be controlled to ensure that the concrete of the pile body is dense and meets the strength standards.

6. Pile formation inspection and maintenance: After pile formation, the integrity of the pile body shall be inspected as per regulations, such as ultrasonic or low-strain testing. Proper maintenance of the pile heads should be carried out to ensure the growth of concrete strength and provide a reliable foundation for subsequent projects.

Conclusion: The key to the construction of rotary drilling RIGS lies in strictly controlling the details of each link. From site preparation to pile formation and maintenance, every step needs to be operated in a standardized manner. Through scientific management and technical control, the advantages of rotary drilling RIGS can be fully leveraged to ensure the safe and efficient completion of pile foundation projects.
