09 Dec 2024 CW Team

Afcons Infrastructure achieved a significant milestone in Delhi Metro Phase IV by completing the longest tunnelling drive between the Tughlakabad Airforce Launching Shaft and Maa Anandmayee Marg Station on the Tughlakabad-Aerocity corridor.

Rajiv Dhankher, Director of Projects and Planning at the Delhi Metro Rail Corporation (DMRC), along with other senior DMRC officials were present on the occasion.

“Tunnel Boring Machine (TBM) AMRIT successfully completed 2.65 km of boring through mixed soil and hard rock strata today. It is the longest tunnelling drive in phase-IV of Delhi Metro. Frequent cutter replacements were required to bore through the hard rock. The tunnel drive alignment was meticulously planned to avoid passing beneath heritage structures adjacent to Mehrauli Badarpur Road,” said S Paramasivan, Managing Director, Afcons Infrastructure.

The DC-07 package includes three stations, 11.26 km of tunnelling, a 223-m ramp, and a 119-m cut-and-cover section. The three underground stations are Maa Anandmayee Marg Station, Tughlakabad Railway Colony Station, and Tughlakabad Station. This package is part of the Aerocity to Tughlakabad Corridor (Line-10) of Phase-IV of the Delhi Metro, with a total route length of 23.62 km.

The 105-m-long TBM was used in achieving this significant tunnel breakthrough. The new tunnel has been constructed at an average depth of approximately 16 m, with around 1,894 rings installed, each with an inner diameter of 5.8 m.

Two parallel circular tunnels for up-and-down movement are being constructed along this stretch as part of the Aerocity–Tughlakabad corridor. The breakthrough on the other parallel tunnel is expected in January 2025.

Dhalbhumgarh Airport Faces 150-km Rule Hurdle

The issue has resurfaced following a recent statement by Union Civil Aviation Minister Ram Mohan Naidu, who said that under existing aviation policy, a new greenfield airport is generally not permitted within an aerial distance of 150 kilometres of an operational civilian airport. He added, however, that if a formal proposal is submitted, its impact on the existing airport can be examined and relaxations may be considered on a case-by-case basis. While the clarification has revived some hope for Dhalbhumgarh, it has also underlined the scale of the technical challenge facing the project. Unde..

Stakeholders Seek Parallel Ops For Vizag Airports

With road and metro rail links to Bhogapuram still several years away, stakeholders in north Andhra Pradesh have renewed demands to continue civil operations at INS Dega even after the commissioning of Bhogapuram International Airport. The new airport is expected to begin commercial operations from June. Officials said close to 80 per cent of the airport infrastructure at Bhogapuram, including the terminal building and internal approach roads, has already been completed. However, inadequate external connectivity remains a key concern. Making a case for parallel operations, Andhra Pradesh Air ..

Govt To Roll Out V2V Tech To Cut Road Crashes

In an effort to curb road accidents, particularly in low-visibility conditions such as dense fog, the government is set to roll out vehicle-to-vehicle (V2V) communication technology that will allow cars to exchange real-time data and alert drivers to potential dangers. The announcement was made by Union Road Transport and Highways Minister Nitin Gadkari after the 43rd meeting of the Transport Development Council. The technology involves installing an on-board unit (OBU) in vehicles, enabling wireless data exchange between nearby cars. This will allow vehicles to share information such as spee..
