Underground Tunnel Line 1

Quito, Ecuador

MAX FRANK Spain supplied fibre concrete spacers for the production of precast concrete parts for the Quito subway tunnel. A total of 30 containers were supplied.

The following product properties were essential for the selection of the fibre concrete spacers:

  • High loads
  • Low water absorption
  • Reduced tolerances in the vibrating formwork

The Quito Metro is an underground rail mass transit system consisting of a single line in Quito, the capital of Ecuador.

The length of the underground tunnel of line 1 is 19 kilometres. Three tunnel milling machines worked in parallel on different tunnel openings. Seven different segment moulds were used for tunnel construction, a total of 42. The progress of the machine allowed a laying speed of one ring with seven segments per hour.
