Key Points of Construction for Rotary Drilling RIGS

Rotary drilling RIGS, as highly efficient equipment for modern pile foundation construction, are widely used in construction, transportation and other projects due to their fast hole-forming speed and strong adaptability. Mastering the key points of its construction is the key to ensuring the quality and safety of the project.

1. Site preparation: The site needs to be leveled, obstacles removed, and the bearing capacity of the foundation ensured to meet the requirements for machine operation. At the same time, drainage facilities should be well established to prevent water accumulation from affecting construction.

2. Pile position marking: Precisely measure and position based on the design drawings. Mark the pile positions with wooden piles or steel bars. The error must be controlled within the allowable range of the specifications to provide an accurate reference for subsequent hole formation.

3. Positioning of the drilling rig: Place the drilling rig steadily beside the pile position, adjust the verticality of the drill pipe, ensure that the center of the drill bucket is aligned with the center of the pile position, and reduce the deviation of hole formation.

4. Hole-forming operation: Select appropriate drilling tools based on geological conditions. Control the speed during drilling. When encountering hard soil layers, slow down appropriately. Clear the debris in the hole in a timely manner to ensure the stability of the hole wall.

5. Hole cleaning and inspection: After the hole is formed, it should be cleaned to remove the sediment at the bottom of the hole. Use tools such as measuring ropes to check the depth and diameter of the hole. Only when it meets the design requirements can it proceed to the next process.

6. Hoisting of steel cages and concrete pouring: The hoisting of steel cages should be slow and steady to avoid colliding with the hole walls. Concrete pouring should be carried out continuously, with the burial depth of the conduit controlled to ensure the quality of the pile body.

In conclusion, the construction of rotary drilling RIGS requires strict control over every link, from site preparation to concrete pouring, as each step is related to the quality of the pile foundation. Only through standardized operation can its efficiency be fully exerted and a solid foundation be laid for the project.
