Kochi Metro tries out monopile technique

The project cost and the quantum of land needed for Kochi Metro Rail will come down if the trial run on the monopile technique succeeds. This will also lessen traffic disruption during the metro rail construction and speed up works when compared with pillars built over multiple pile groups. The multiple piles have three or four piles, each pile having a diameter of 1 metre. The monopile trial began near the KSRTC’s main bus stand here on Friday. “This will go on for two or three days and a report will be ready in a fortnight,” said a DMRC official.
In this, a 1,275-tonne vertical test load and 60-tonne lateral load will be loaded incrementally on a monopile having a two-metre diameter. “An instrumentation team will monitor the trial using strain gauges embedded in the pile. The incremental loading will be carried out for around two days and this will be 1.5 times the designed load. This 50 per cent extra load has been factored in as a safety measure. We also did a modern integrity test using cross-hole sonic method,” said...
