A tunnel boring machine (TBM) is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata. They may also be used for micro tunneling. In Japan and China, The machine is used for soil are called shield tunneling machines and machines used for hard rock are called tunnel boring machine.
The SBU-A is a small diameter rock cutting head (from 24″/600 mm to 72″/1.8 m) that can be used with any Auger Boring Machine (ABM) to excavate hard rock on drives less than 500 ft (150 m). The Robbins SBU-A has been proven on hundreds of jobs across the U.S.

Oct 10, 2018· A Main Beam TBM is great for digging through hard rock. The Robbins company states that if you want to drill through hard rock in the shortest time possible, then the Main Beam machine is the way to go. The cutter-head is the same size as the tunnel diameter, and the machine works by thrusting disc cutters into the rock while the cutter-head ...

Don’t let tough soil conditions dictate your utility project timeline. Push through with the Barbco 36/42-500 auger boring machine. Designed to manage extreme ground conditions, including hard rock and clay, the 36/42-500 offers the advanced strength you need for longer bores between 4” and 36” in diameter.
Aug 11, 2020· Horizontal drills, or directional drills, are used in utilities, oil and gas, and other industries that require directional drilling or boring through rock, hard soil, and other materials. This makes them distinct from vertical drills, which, as the name implies, usually only drill straight down.
This enables millimeter-precise boreholes also in hard geologies and soft rock. For steel pipe jacking without hollow stem augers, an electronic water leveling system with an inclinometer is used as a surveying system. This means this technology can be used for every boring machine and with conventional augers.
