How to remove rocks from a rock work site?

The needs :Conventional rock removal method-drill and blast- has been restricted in rock work sites due to vibrations, sounds, and flying rocks. So alternatives had to be used. Chemical expansion agents, Cracking capsules, Hydraulic wedge splitters, and Hydraulic piston type splitters have been tried .

Are hydraulic piston splitters suitable for hard rock demolition?

Hydraulic piston type splitter seems to meet these important factors satisfactorily. The requirements in hard rock splitting: In the beginning edge type splitters were used. However they are somewhat weak for hard rock demolition. Hole spacing is so densely made. Otherwise splitters could not break rock at all.

How do you demolish a concrete pile?

pile head and demolish it with a splitter (2) (Fig. B) d by hand. .Fig. 8.5.2b) Lightly reinforced concrete:Instead of exposing the reinforcing rods, drill a hole in the side of the pile between reinforcing rods nd make a limiting split (1) with a splitting cylinder. Do not enlarge this split excess

How to depressurize a hydraulic system?

le and the splitting process repeated in the next hole.5) To depressurize the hydraulic system on completing splitting operations or before a prolonged break, it is advisable to switch off the hydraulic pump unit or at least to set the control valve lever to the central, neutral position, otherwise the hydraulic fluid in the
