Tunnel Support System




The detailed study for construction of the tunnel include understanding with respect to the choice of the liner & method of excavation, the challenges posed by the  stratigraphy, the joint patterns, seapage zones, etc. For this Geological Mapping and Pressuremeter & Flat Jack tests form the important tools. Many markets have been served by Noble Geo-Structs:


  • Water supply tunnels

These projects are completed for Brihanmumbai Municipal Corporation (BMC). The depth for these tunnels have been about 100 m below the ground level.


  • Metro

The safe excavation procedures along with the design for tunnel liners using extensive Finite Element Method (FEM) have been recommended.


  • Railways

The geology of the proposed area for tunnel was analysed by conducting extensive geological mapping and running large number of Pressuremeter tests at the crucial locations.


Recently the tunnel projects are completed at:
Surya tunnel
Kashedi ghat
Airoli - Katinaka
Valecha - Jharkhand
Jite Tunnel
Lukhnow tunnel - Metro Rail Phase 1A
Malbar Hill – S.K. Patil Udyan – Kilachand Garden
Modaksagar Tunnel
Bhandup-Malad-Charkop Tunnel
