When boring the ground, it is essential that you first determine a starting point of where the process will commence. A clamshell post-hole digger is efficient for this procedure. This digger consists of two handles and two blades, joined at the center by a pivot. Bury the blades and press the handles outward to clamp soil and release the handles to the central position to release the excavated soil. Making a small indentation in this manner will allow you to line up your larger equipment properly.
Augers are large, twisted drill shafts that vary in shape. There are different types of augers depending on the depth and type of rocks that you are boring through or extracting. A gas-powered auger is suitable for digging through rocks. A vehicle-mounted auger can be used to dig shallow holes. Hand-held augers are designed for operation by a single person.
Shoring tools are important when boring holes more than four feet deep. Use these tools to break apart rock particles along lines of weakness into smaller pieces that can later be broken down with hand tools. Examples of shoring tools include hydraulic hoses, hydraulic cylinders, pumps and couplings. Hydraulic tools employ pressure to break the ground while the pump brings in water to loosen the rocks.
You will use various hand tools if you intend to dig along vertical lengths underground. Tools such as picks and mallets are useful for this. Other tools such as trolleys, spades and hoes are for collecting the broken down material and transporting them outside the tunnel.
