Types of Underground Boring Machines
Underground boring machines are a crucial part of tunnel construction, offering an efficient and safe way to excavate beneath the Earth’s surface. With advancements in technology, these machines have become increasingly sophisticated, providing a range of options for various tunneling projects.
The primary classification of underground boring machines is based on their operational principle, dividing them into mechanical and non-mechanical categories. Mechanical machines, also known as conventional tunnel boring machines (TBMs), rely on physical cutting tools to excavate the tunnel wall. In contrast, non-mechanical machines, such as road header machines, employ mechanical or hydro-mechanical cutting principles to remove material.
Working Principle of Tunnel Boring Machines (TBMs)
Tunnel Boring Machines (TBMs) are the most commonly used mechanical underground boring machines. They operate by employing a continuous disc cutter or a cutterhead attached to a rotating drum. As the cutterhead spins, it cuts a tunnel section, which is then transported outside the machine for processing. TBMs can excavate at a wide range of cutting depths and speeds, providing flexibility for various project requirements. Their robust design and advanced automation features enable efficient, minimally-invasive tunneling in dense rock formations and unstable soil conditions.
Applications of Road Header Machines in Underground Tunneling
