Tunnel ground improvement: What is at stake?

The construction of tunnels in poor soil or in varied soil conditions provides for a variety of unique challenges. When building a metro or irrigation tunnel, it is necessary to account for:

  • The structural sustainability against water pressure,
  • The soil reinforcement using grout injections and clouting (if a tunnel is built with a traditional method).
  • The cross-passages to create connections between two tunnels,
  • Adequate protection for the surrounding buildings and underground infrastructure networks along the tunnel
  • Convergence areas between two tunnels: where ground stability is concerned, it is of absolute necessity to make sure that the construction of one tunnel will not impact the construction of the other.
  • How VSL can help you

    VSL-Intrafor has extensive experience in all ground improvement solutions – even when complex in nature (depth, complicated environmental setting).
    The solution depends on structural requirements or existing soil conditions:

    • grouting,
    • jet grouting,
    • stone columns,
    • vibro-compaction,
    • ground freezing.

    VSL Intrafor manages over 400 pieces of specialized equipment including ground improvement machinery such as vibroflots, stone columns equipment, grouting pumps and jet grouting pumps.
