THE DEMAND FOR UNDERGROUND INFRASTRUCTURES.

  • Population growth and urbanization
  • New high-capacity infrastructures to keep

people, goods and resources on the move

  • Longer and deep grounded tunnels in all kinds
  • f geologies for every traffic and utility tunnel
  • Huge diameter multi-purpose tunnels
  • Large scale infrastructure schemes with many

simultaneous sub-projects

  • Tunnels for megacities
  • High-speed trains, hydropower, irrigation,

sewage

FLORENCE (S-376) FASTER THAN MATHILDA (S-375).

  • S-375: Difficulties with mortar in the beginning
  • S-376: Higher weekly performances because of a different shift

model (S-375: 5x22h= 110h/w; S-376: 7x24h= 168h/w)

The challenge:

  • Underground assembly,

dismantling and re-assembly (with extended diameter) of TBMs in the tunnel ASSEMBLING THE TBMs. The solution:

  • Time management with just-

in-time delivery of spare parts, new and refurbished parts

  • Special transport equipment
  • Taylor-made engineering in

cooperation with the jobsite

SECURING THE BORED TUNNEL. INNOVATION POTENTIAL WANTED.

  • Geology: changing geological

conditions

  • Not to determine the TBM–

performance

  • Has to be efficient, a taylor–

made device

  • Give a secure job as a safety

measure

MECHANIZED TUNNELLING FOR NEW, HIGHLY EFFICIENT INFRASTRUCTURE FOR TRAFFIC AN SUPPLY SYSTEMS. SUMMARY AND PERSPECTIVES.

  • Now and in the future: Demand for high-efficient infrastructure
  • High-tech tunnelling systems for all diameters up to 19 meters and

all geologies

  • Teamwork Tunnelling to guarantee best possible project success
  • Finding solutions for financing and operating
