When the rotary drilling rig hits the slope protection pile, it is necessary to pay attention to the following aspects:
1. Preparation before construction.
Before starting to drill slope piles on a rotary drilling rig, sufficient preparation is required. First of all, the construction site needs to be cleaned and leveled to ensure that the rig can be stably installed on flat ground. Secondly, it is necessary to check whether the various components of the rotary drilling rig are intact, especially the key components such as drill bits, drill pipes, and transmission systems, and if there are damaged or seriously worn parts, they need to be replaced in time. At the same time, it is also necessary to determine the position and depth of the slope protection pile according to the design requirements, and carry out the pre-construction measurement and positioning work in accordance with the relevant specifications.
Second, the control of the drilling process.
During the drilling process, the following points need to be noted. First of all, it is necessary to choose the appropriate drill bit and drilling depth according to the geological conditions and design requirements to ensure the quality and safety of the drilling. Secondly, it is necessary to control the speed and pressure of the drilling to avoid the wear of the drill bit or the quality of the slope protection pile caused by too fast or too slow drilling speed. At the same time, it is necessary to pay attention to the verticality and depth of the drilling hole at all times, and adjust the position and angle of the drilling rig in time to ensure that the position of the drilling hole is accurate. In addition, it is necessary to pay attention to the geological changes in the drilling process, and take measures to deal with any abnormalities in time.
3. Detection of hole quality.
When it comes to hole quality inspection, it is necessary to use appropriate methods for inspection. Commonly used detection methods include ultrasonic testing, radiographic testing, etc. The test needs to be carried out in accordance with relevant norms and standards to ensure the accuracy and reliability of the test results. If it is found that the quality of the hole does not meet the requirements, it is necessary to take measures to deal with it in time, such as hole cleaning, hole filling, etc.
