Design of the works

Works out of the commun run

  • Program and objective
  • the Geology: With the research of the blue Chalk
  • the layout: Full and long sinuosities
  • Topography: to join the two ends.
  • Technical and methods

Tubes and rooms

  • the Coating: a solid carapace
  • the Branches: from one tube to another
  • the Pumping station
  • the railway Crossing
  • the Gate of Beussingues
  • the final installation of the Well of Sangatte
  • works of surface

Realization of the works

Installations of Sangatte

  • buildings of surface
  • the Well of Sangatte: a gigantic heart
  • the equipment of the well
  • spoil: how to get rid
  • of it provisioning of the convoys
  • the operation of the sector well-surface

Design with the first turns of wheel

  • the Tunneller S
  • Five prototypes
  • the assembly of the tunnellers in the well
  • How to work in dry ground
  • the Digging: like a mole and a caterpillar
  • the piloting computer-assisted
  • the coating: longest Alarming specter
  • the railway equipment: six ways for the face
  • industrial water: two feeder systems
  • electricity: working installed capacity: 80.000 KW
  • the Pumping out: to drain the tunnels
  • ventilation: to bring oxygen to the face

Tunnels under sea

  • the Tunnel under sea T1: the exploit with a prototype
  • teams of the T1
  • tunnellers T2 and T3
  • the T3: a “formula 1”
  • the T3 with the use
  • teams of T2 and T3
  • the Junction of the tunnels
  • measurements after junction

Tunnels under ground

  • the Tunnel under ground T4
  • the T5/T6: a spectacular Reversal
  • teams of the tunnels under ground

The special Works

  • the Branches: a building site with share
  • the Pumping station W3: a realization into traditional
  • the railway crossing

The Equipment of the tunnels

Transport - Communication and safety
