The speed of the single bucket needs to be controlled during the drilling process. , The speed of the power head, and the lifting speed of the main winch. Reduce the disturbance to the hole wall and ensure the quality of the pile. an lang=EN-US>The stratum above 10 meters is red clay with relatively high viscosity, and the hardness of strongly weathered mudstone below 10 meters is 5-10Mpa. Because the stratum is all clay structure, the dry hole construction method is adopted. The drilling footage is 400-500mm, and the footage is about 300mm after the groundwater layer is drilled. The average time for each hole to be formed is 1 hour and 30 minutes.
