4 Sudarshan TBMs released by NCRTC for tunnelling at Anand Vihar station
A top-down approach is being used to build the RRTS Anand Vihar station. Construction of the ground level is completed before moving on to the underground level. Cut-and-cover construction is being used to build this RRTS station.
The side walls, which are roughly three feet wide, are built first. Iron temporary columns have been set up. The top slab is built first, and a small opening is made through which excavator vehicles can descend and remove the earth. The temporary columns are then replaced with permanent ones. Raft and the remaining construction then take place. The entire construction project continues underground without interfering with other activities. The station's lowest floor, which is not accessible to the general public, will be used for maintenance and drainage.
