  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 eq...

The selection of down-the-hole drilling rigs mainly considers several factors, such as the diameter, depth, direction, angle and drilling accuracy of engineering blast holes, rock conditions, construction site conditions and construction period. Then select the appropriate rig according to these requirements, and match the corresponding air compressor. At present, large, medium and small are widely used in the domestic market. High, medium and low wind pressure, track tread and rubber tread methods; driving forces include diesel engines, electric motors, wind motors and other models. At present, the  hydraulic dth drilling rig  for small and medium crawler walking is analyzed as follows. Power type of drilling rig. There are three basic types of power for domestic small and medium-sized crawler self-propelled DTH rigs. The rig is driven by a diesel engine to drive a group of hydraulic oil pumps, and the output hydraulic oil is separately supplied. 1. Walking hydraulic motor...
