Metro Rail site in Shenoy Nagar Park, which got the first consignment of tunnel boring machine Underground tunnels of metro rail, will be reinforced with concrete walls which will shore up the tunnels as it passes underneath busy roads and buildings across the city. These walls will be made in segments using specially designed molds and will be transported to work site so that they can be installed simultaneously when machines start boring. Metro rail has started work to build diaphragm walls to lower tunnel boring machines at Egmore, Washermanpet, Shenoy Nagar, May Day Park and Kilpauk Medical College. 

Tunnel boring machines, which have arrived from China, will be lowered at Washermanpet and Shenoy Nagar where diaphragm walls will be completed. Around 22 diaphragm wall panels are made and a guide wall has been completed at May Day Park, while 24 diaphragm wall panels at Shenoy Nagar and 19 others at Washermanpet have been installed. 

The boring machines will be lowered at these locations when the diaphragm walls are constructed and a pathway tunnel designed to guide the machines to the boring spot is completed. Work to build underground stations is progressing at a brisk pace along Poonamallee High Road for the Central-Tirumangalam underground section and along Anna Salai for Washermanpet to Saidapet underground stretch. Soil investigations are complete and barricades have been set up to identify and move utilities like electrical junction boxes, water supply pipelines and others.

Huge Chinese-made tunnel boring machines are in action in Chennai for the Metro Rail project. Eleven machines will be used to excavate the underground sections.
