24X7 Geotechnical Monitoring Instruments Used for Bullet Train Project
Various types of Geotechnical Instruments, including Inclinometers, Vibration monitors, Ground settlement markers, and Tilt meters, have been installed at and around construction sites to monitor tilt, settlement, vibration, cracks, and deformation. These instruments are vital in ensuring the safety of ongoing underground works like excavation and tunneling, as well as the surrounding structures. Geotechnical Instruments are connected to their respective modules to record and monitor activities, enabling the timely identification of potential risks and interventions to mitigate them.
Additionally, dust and noise monitors are being installed at construction sites to ensure that noise and air pollution remain within permissible limits in the vicinity of the construction sites.
Construction activities are underway for the 21 km long underground portion of the Bullet Train corridor in Mumbai and Thane districts of Maharashtra. These activities include excavation for a 1 km long and 32-meter-deep underground Bullet Train station at Bandra Kurla Complex, as well as the construction of shafts and portals for tunneling works.
Three mega Tunnel Boring Machines (TBMs) will be deployed for 16 km tunneling work, including a 7 km undersea tunnel, with the remaining 5 km using the New Austrian Tunneling Method. The depth of the tunnel will vary from 25 meters to 57 meters. Three Shafts, one ADIT, and a portal are being constructed for the deployment of Tunnel Boring Machines.
