Testing of rubber geomaterials is being done while building a 3.2km elevated corridor on Anna Salai

Testing is underway for geographic grids, geo cells and geosynthetic materials using rubber for construction of a 3.2 km long elevated corridor in a stretch running on the Metrorail tunnel at a cost of Rs 62.21 crore.

M-SAND is filled in geographic grids and geographic cells and is compacted with water at 50 plus locations to enhance soil on the tunnel. Inspection of highways on the project site on Sunday Minister Velu urged contractors to speed up work.

He said soil strengthening has been tested and approved by the IIT Soil Mechanics Department of Mumbai. He said this was the first time to board a building in an underground tunnel.

Sources from the expressway department explained that three stretches are being built – 655 tons, with no tunnels where pile foundations are being built at 22 sites. At the tonnage of 1955, 69 Micropiles are being built, and in Teynampet’s 460 MT, Nandanam Metro Stations Provisions have been developed for the portal framework.

Steel columns are used in tectonic corridors, not concrete columns, and not in the construction of this corridor, and Chief Minister MK Stalin laid the foundation for the foundation in January 2024. “These will be pre-made to help quickly structure and reduce the weight of the structure. The weight of steel will be 2/3 of the concrete ress.

Once completed, the corridor will allow motorists to cross seven traffic lines on Eldams Road, Suit Academy, Karnop Road, South Nanham, Ke Nagar, Ke Nagar, Todd Hunter Nagar-Jones Road, about 2.37 million vehicles a day, about 2.37 million vehicles. This work was carried out through the engineering procurement structure contract model.

Senior officer R. Selvaraj, chief engineer (building and maintenance wing), Sathyaprakash, special technical officer R. Chandrasekar, principal M. Selvakumar and department engineer (C&M wing), Chandrasekar, Chandrasekar appeared during the inspection.
