What Are The Key Points in The Construction of Rotary Drilling RIGS

Rotary drilling RIGS, as the core equipment in modern pile foundation construction, are widely used due to their high efficiency and flexibility. However, during construction, it is necessary to strictly control the key links in order to ensure the quality and safety of the project.

1. Site investigation and preparation: Before construction, it is necessary to clarify the distribution of underground pipelines and geological layers, level the site and compact it to prevent settlement during the operation of the drilling rig. At the same time, plan the areas for mud circulation and construction waste storage well.

2. Drilling rig positioning and debugging: Precisely position the drill pipe based on the pile position coordinates, and adjust the verticality of the drill pipe. The error must be controlled within the specified range. Before starting, check the power system and hydraulic devices to ensure stable operation.

3. Drilling parameter control: Select the type of drill bit based on geological conditions. For soft soil layers, the drilling speed can be appropriately increased. For rock layers, the rotational speed should be reduced and the pressure applied should be controlled to avoid stuck drill or drill pipe breakage.

4. Mud Management: The specific gravity and viscosity of the mud should be adapted to the geological conditions. Mud can be naturally produced in clay layers, while in sand layers, mud needs to be artificially prepared to protect the walls and prevent collapse. At the same time, sediment should be cleared in a timely manner to ensure the performance of the mud.

5. Hole formation quality inspection: After hole formation, the hole diameter, depth and verticality need to be measured. If problems such as diameter reduction or hole collapse occur, remedial measures such as backfilling and re-drilling should be taken promptly before proceeding to the next process.

6. Safety Operation Norms: Operators must be certified to work and wear protective equipment during operation. In case of bad weather such as heavy rain or strong wind, work should be stopped immediately to prevent equipment damage or casualties.

In conclusion, the construction of rotary drilling RIGS should integrate technical specifications with the actual situation on site, and control the entire process from the initial preparation to the hole formation. This not only enhances construction efficiency but also lays a solid quality foundation for pile foundation projects and reduces the risk of rework in the later stage.
