How To Drive 45-degree Inclined Piles with A Rotary Drilling Rig

In construction, the construction of 45-degree inclined piles is somewhat challenging. As a commonly used equipment, it is crucial to master the correct operation method for rotary drilling RIGS. Now I'll tell you how to drive a 45-degree inclined pile with a rotary drilling rig.

1.Site preparation and equipment debugging: First, level the construction site to ensure it is solid and free of soft areas, and prevent the drilling rig from tilting. Meanwhile, a comprehensive debugging was carried out on the verticality control system of the rotary drilling rig, the rotational speed of the power head, etc., to ensure the good performance of the equipment.

2. Installation of positioning and guiding devices: Precisely position the pile positions based on the design drawings, and then install the dedicated 45-degree inclined pile guiding frame or guiding device to ensure its firm fixation, providing an accurate guiding reference for the inclined pile construction.

3. Positioning and Angle adjustment of the drilling rig: Slowly drive the rotary drilling rig to the pile position. Use the hydraulic adjustment system of the equipment in combination with the guiding device to adjust the drill pipe to a 45-degree inclination Angle. Repeatedly calibrate to confirm that there are no errors.

4. Key points of drilling construction: When starting to drill, control the drilling speed well and maintain a constant speed to avoid the drill pipe shaking and pile position deviation caused by excessive speed. Meanwhile, closely monitor the changes in drilling pressure and torque, and adjust the parameters in a timely manner according to the geological conditions.

5. Lowering the steel cage and pouring concrete: After drilling to the designed depth, clear the sediment at the bottom of the hole, and then lower the steel cage to ensure its accurate position. Concrete pouring is carried out by the conduit method. During the pouring process, continuity is maintained to prevent pile breakage.

6. Inspection and maintenance after pile formation: After pile formation, the quality of the pile body and the inclination of the inclined piles should be inspected in accordance with the specification requirements. At the same time, proper maintenance work should be carried out. Measures such as covering and watering should be taken according to environmental conditions to ensure that the strength of the pile meets the standards.

When using a rotary drilling rig to drive 45-degree inclined piles, every link is closely connected and cannot be ignored. Only by strictly following these steps and paying attention to detail control can the quality and efficiency of inclined pile construction be guaranteed and the requirements of engineering construction be met.
