How many times a day will the drilling machine be used?
It depends on the geological soil, as well as the diameter and depth of the pile.
According to geological conditions and diameter of piles, it is usually between 30 and 60 meters
Look at the actual situation, usually of rotary drilling rig, such as diameter 120cm length of 30 meters, the geological conditions in general, 1.5 to 2 hours to complete. You can calculate the amount of work done every day.
