The
USBRL project is one of the largest and perhaps the most challenging
railway projects in the world. The 312 km railway line is being built
from the city of Udhampur, North of Jammu to the city of Baramulla at
the North Western Edge of the Kashmir Valley. Udhampur is already
connected to the rest of India through Jammu. The railway line will thus
connect the Kashmir valley to the rest of the Country.
Encardio-rite was awarded the instrumentation and monitoring contract for almost 20 large tunnels
on this rail link project. The toughest section of this stretch is the
90 km long Katra to Laole section in which 80% of the railway line
passes through a tunnel or is on a bridge. IRCON, Indian Railways and
Konkan Railways are in-charge of executing the various sections of this
massive project.
Besides supplying the instruments, Encardio-rite
has also been entrusted with the installation and monitoring of the data
through a large number of qualified, trained and experienced engineers.
A large number of sensors used in this massive project include:
- Rock (anchor) bolt load cells
- Piezometers
- Concrete pressure cells
- Shotcrete/concrete stress cells NATM style
- Shotcrete strain gage
- Embedment strain gage
- Multipoint borehole extensometers
- Measuring anchors
- Base load cells
- Inclinometer system
- Tape extensometer
- Bi-reflex targets (in thousands)
- Readout units
