Encardio-rite
normal and inverted plumb lines are simple and reliable systems that are widely
used in civil engineering projects where highly accurate long-base
rotation/tilt/relative displacement measurements are required, like in high
rise buildings, concrete and masonry dams, etc.
Plumbline is mainly used in concrete and masonry dams for measurement and monitoring
of relative displacement between:
Normal Plumb line
This assembly is used when displacement between the top and base of a dam is to be measured and monitored. Model EDS-50 normal plumbline consists of a plumb line wire fixed through a collet arrangement centered on a rectangular collet bar at the top of the structure/dam. A heavy weight is clamped at the lower end of the wire, which is damped in a tank filled with oil, to prevent any to & fro oscillatory movement of the plumb due to vibration or shock.
Inverted Plumb line
The assembly is used when the displacement between the base of the dam and the rock foundation is to be measured and monitored. Model EDS-51 inverted plumb line monitors displacement between the structure/dam base and rock foundation. The plumb wire is anchored between rock foundation (bottom of drilled hole) and float submerged in a water tank in the observation area. A tension is maintained in the plumb wire as the float is free to move. Water in tank acts as a damping medium. A tilt or displacement in the foundation brings about a shift in the float which is measured by readout systems mentioned above.
For talking measurements, Encardio-rite provides two options:
MODEL EPR-01S is a very simple and reliable system that is widely used in civil engineering projects. It measures highly accurate long-base rotation, tilts or relative displacements whenever required. This device is used in high-rise buildings, concrete and masonry dams, nuclear plants etc.
