Preparation Work Before Hydraulic Dth Drill Rig Construction.
The construction of hydraulic down-the-hole drilling rigs has the characteristics of fast hole formation, high quality, no noise, and no pollution. Because of its unparalleled advantages in the construction of cast-in-place piles, it is favored by more and more construction units. Therefore, the current price segment Drilling rigs are the main force in underground engineering construction. 1. Construction site: hydraulic DTH Drilling Rig for pile foundation construction. In the preliminary preparation stage, the construction site is required to be high. Due to the heavyweight of the rotary drilling rig, the operation of the rotary drilling rig requires the machinery to remain stable, so the operation The site reaches a certain bearing capacity. If the working surface is a relatively soft stratum, the supporting layer should be backfilled so that the site can carry the hydraulic DTH Drill Rig , and the cranes (above 25t), concrete filling trucks and other equipment for supporting c
