Tunnel Boring Machine: Working of the Tunnel Construction …
A tunnel boring machine (TBM), also known as mole, is employed for the construction of tunnels in hard or soft rock strata. The cutting process utilizes the rotation of the cutterhead (geared with disc cutters) and the blade pressure for excavation on the face of rock.
Boring Machining: Techniques, Advantages, and Applications
1. Construction Types. Horizontal Boring Machine: Operates horizontally and is ideal for processing large, heavy workpieces.The horizontal design enhances stability when machining bigger parts. Vertical Boring Machine: Operates vertically, suitable for heavy-duty tasks.This type is commonly used in industries like automotive and aerospace, where large, heavy parts require precise machining.
Tunnel boring machine - Wikipedia
A tunnel boring machine (TBM), also known as a "mole" or a "worm", is a machine used to excavate tunnels. Tunnels are excavated through hard rock, wet or dry soil, or sand, each of which requires specialized technology. Tunnel boring machines are an alternative to drilling and blasting (D&B) methods and "hand mining".
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. TBMs can bore through any geological strata ranging from hard rock to sand and mixtures of soil & rock. Tunnel diameters range from a metre (done with micro-TBMs) to 19.25 m. Tunnel boring machines are ...

The Evolution of Tunnel Boring Machines - by Brian Potter
2023年10月6日 · A common way of building a tunnel today is with a tunnel boring machine (TBM), particularly in urban areas where other construction methods such as drill-and-blast or cut-and-cover would be too disruptive. Of the 89 transit projects around the world that required tunneling in a dataset compiled by Britain Remade, 80 of them used TBMs. But ...
