An Auger Boring Machine (ABM) is used to bore horizontally through soil or rock with a cutting head and auger. The majority of ABMs are used to install pipe casing under railroads, highways, airport runways, creeks or any area of ground that cannot be open cut or disturbed in any way.
There are many types of cutting attachments for this machine. They range from Backhoe Teeth cutters for cutting through soil to the Robbins Small Boring Unit for boring hard rock.
Initially the ABM is set up in the starting pit on a predetermined length of track. A backing plate, usually steel or reinforced concrete block, is installed in the wall opposite of the boring to withstand the thrust exerted by the boring machine. The machine bores through the earth with a cutting head and the jacking force is provided by the hydraulic thrust. The pipe casing and auger sections are added as the machine advances. Spoil is removed from the auger through the casing to a door located on the side of the machine.
