Boring is a process in which a hole is drilled into the ground for purposes including utility installation, geological exploration, mining and many others. It's also commonly used to create underground pathways for pipes, conduits and cables in building projects.
There are several types of boring in construction, each with its own unique characteristics and advantages. Some are more powerful and effective than others, so you may want to consider different techniques before settling on one for your project.
Auger boring is a popular method for testing the stability of soil and determining if a site is suitable for construction. It involves penetrating the soil layer with a sharp, flexible auger.
Rotary drilling is another common method for advancing bore holes. In this method, a rotary percussion drill bit is advanced into the soil by recurrent blows from a heavy string of drill rods.
A slurry is created by circulating water or drilling mud through the rods and the churn bit, which removes broken rock or soil fragments. The slurry is then collected in a settling tank for recirculation.
Horizontal boring is another method for completing test bores for piping. This technique is especially useful for projects requiring installation under a roadway, railroad or lake or river.
The procedure is usually conducted under controlled conditions, such as a paved surface. It can be used for larger diameter tests and is usually less expensive than intermittent sampling.
