Tunnels in hard rock. Tunnels in soft materials. Tunnels underneath river bed or in water-bearing soils.
Tunnel Construction Tunnels are dug in types of materials varying from soft clay to hard rock. The method of tunnel construction depends on such factors as the ground conditions, the ground water conditions, the length and diameter of the tunnel drive, the depth of the tunnel, the logistics of supporting the tunnel excavation, the final use and ...

When a tunnel passes through different types of material it is known as mixed face construction. In bored tunneling, the excavation takes place at the portal or at a shaft, thus the is a minimum impact on usual traffic, air & noise quality, and utilities.
A tunnel is an underground passageway, dug through the surrounding soil/earth/rock and enclosed except for entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods.
The Holland Tunnel, completed in 1927, was one of the first roadway tunnels and is still one of the world's greatest engineering projects. Named for the engineer who oversaw construction, the tunnel ushers nearly 100,000 vehicles daily between New York City and New Jersey. Tunnel construction takes a lot of planning.
A tunnel construction is an underground passage provided beneath earth surface or water. Different methods of tunnel construction and their details are discussed. In most of the cases tunnel construction is expensive but it saves time and provides comfort. Large excavation of soil or rock etc. is ...
Types of Ventilation Systems in Tunnel Construction The methods employed for tunnel ventilation generally depends upon the normal, emergency or congested operation that will be dependent on the actual conditions of the size, cross section, traffic conditions, intermediate ventilation shafts etc.
Types of Tunnels & Construction Methods Tunnels are dug in types of materials varying from soft clay to hard rock. The method of tunnel construction depends on such factors as the ground conditions, the ground water conditions, the length and diameter of the tunnel drive, the depth of the tunnel, the logistics of supporting the tunnel excavation, the final use and shape of the tunnel and ...
Tunnel construction with the Tunnelift range by ACIMEX. ACIMEX know-how in the field of tunnel construction was forged nearly 30 years ago, from 1989 when it worked on the same site as CBE Group for the construction of the Villejust railway tunnel (LGV Atlantique) in Île-de-France.
Tunnel Construction: Soft Ground and Hard Rock - Builders use two basic techniques to advance a tunnel: the full-face method and the top-heading-and-bench method.
KAMY series of Roadheaders offers the best cutting performance in a wide range of rock formations. Equipped with geometrically optimized transverse or longitudinal cutter heads, these flexible machines can be used to excavate subway tunnels, road tunnels, railway tunnels and water tunnels without using explosives.
