tunnelboremasinad
A tunnelboremasinad, also known as a tunnel boring machine (TBM), is a specialized piece of equipment used to excavate tunnels with a circular cross-section through a variety of soil and rock strata. TBMs are typically used for large-scale tunneling projects, such as those for transportation infrastructure, water supply, and sewage systems. They are capable of boring tunnels with diameters ranging from a few meters to over 15 meters, and can be used in both soft ground and hard rock conditions.
The basic components of a TBM include a rotating cutterhead equipped with disc cutters, a screw conveyor
TBMs offer several advantages over traditional tunneling methods, including reduced surface disturbance, improved safety, and faster
