Rotary drilling rig is a construction machinery suitable for drilling operations in building foundation engineering. To efficiently complete tasks during operation, we need to master the following techniques of rotary drilling rig in construction.
1. The rotary drilling rig can perform high-speed pressurized drilling during soft soil operations; Continuous pressure should be applied during clay layer operations to ensure high-speed and low load drilling.
When encountering sand layers with high friction, it is necessary to constantly apply pressure and back pressure, otherwise it will cause machine wear.
3. When working in the gravel layer, avoid hardness spikes and use slow speed drilling.
4. When the rotary drilling rig is operating in stable mudstone and harder gravel layers, don't worry, it is easy to use low-speed drilling.
5. When working on the bottom layer of gravel, it is common to break the edge teeth, so we need to use medium speed drilling.
6. The load and vibration of the rotary drilling rig are different in each project, and the action of the machine is also different. Therefore, it is important to adjust the engine speed well in order to successfully complete the task.
For the new technology of rotary drilling rig construction, we still need to accumulate more experience, and we need to carefully summarize and analyze the problems encountered during construction. I believe that with the deepening promotion of rotary drilling rigs, we will learn more and more, solve problems will become easier, and work will become smoother!
