Auger rigs are specialized drilling machines used to create holes in the ground. They utilize a rotating helical screw, known as an auger, to excavate soil and rock. These rigs are commonly employed in construction, environmental studies, and geotechnical investigations to gather soil samples or install foundations. The design of auger rigs can vary, with some being portable for small projects and others being mounted on larger vehicles for heavy-duty tasks. They are effective in various soil types and can reach significant depths, making them valuable tools for engineers and contractors in diverse applications.
