Posted on: 21/May/2016 11:32:17 AM
The new underground line between Washermanpet and Korukkupet is being readied by the Chennai Metro Rail Limited. This line included two station as part of Phase 1 extension to Wimco Nagar. The line will offer the residents of North Chennai neighbourhoods access to the transport system. It is expected to be ready in 20 months after contract are awarded.
2 kms of the line will run beneath the northern suburbs of New Washerman pet and Korukkupet. The alignment from Thyagaraya College to Korukkupet Junction have been formed up. Also, authorities have marked areas of potential impact of work on the buildings around proposed stations and tunnels.
According to sources, the silty clay soil will make it easy for boring machine to cut through. However, as the stations have to be built around the 2 km stretch, which is extremely congested, the underground stations will be tough. Phase I of the extension line will begin at Washermanpet underground station. This is part of the Airport - Washermanpet corridor. The tunnel for the line will begin near the Mint flyover. This will be bored under the railway line to Beach station.
According to sources, As the soil there is silty, engineers have designed detailed maps showing the impact digging will have on the surface soil. The soil is plastic and there is a good possibility it will settle under vibration from digging for building stations. The alignment has been designed to protect buildings, residents and commuters on Thiruvottiyur High Road from the impact. The changes in the surface soil will be monitored continuously when work begins. The line beyond Korukkupet station will be built using a cut and cover process.Land will be acquired temporarily on either edges of the main road to carry out construction without disturbing traffic.
