Chennai, India (Urban Transport News): Union Minister of Railways, Communications, Electronics and Information Technology, Ashwini Vaishnav, via video Indigenously designed and manufactured – Full Span Launching Equipment – Straddle – to expedite the construction of a viaduct for the Mumbai-Ahmedabad High-Speed Rail Corridor Flagged off the carrier and girder transporter. Conference here today.
The transporter was launched in the presence of other prominent dignitaries, Miyamoto Shingo, Minister, Embassy of Japan; Sunit Sharma, Chairman and CEO, Railway Board; Satish Agnihotri, Managing Director, National High Speed Rail Corporation Limited (NHSRCL); Anupam Kumar and SN Subrahmanyan, CEO and MD, L&T Construction.
Addressing the gathering through video conferencing, Ashwini Vaishnav said that to encourage Atma Nirbhar Bharti Campaign Initiative, 1100MT capacity full span launching equipment is indigenously designed and manufactured by Larsen & Toubro Limited (L&T) at Kancheepuram, Chennai. L&T has partnered with 55 Micro-Small Medium Enterprises (MSMEs). India is now joining a select group of countries such as Italy, Norway, Korea and China that are designing and manufacturing such devices. This will accelerate the construction of high-speed railways, as proven technology in metro and similar projects.
“Work has already started on 325 km (in the state of Gujarat) out of the 508 km corridor between Mumbai and Ahmedabad. Gujarat and Dadra and Nagar Haveli acquired more than 97% of the land for the project and 30% land in Maharashtra The project will improve skills in various rail construction technologies. The Japanese counterpart will also provide training to employees and contractors of the National High-Speed Rail Corporation Ltd. More than 6000 workers are already working at various construction sites for the project. Thus creating employment opportunities for the local youth,” he said.
He further said that the Mumbai-Ahmedabad high-speed rail project is expected to create over 90,000 jobs in the sector, including 51,000 jobs for technicians, skilled and unskilled workers. The project will boost the overall economy of the region by deploying thousands of trucks, dumpers, excavators, batching plants, tunneling equipment, etc. It is estimated that 7.5 million tonnes of cement, 2.1 million tonnes of steel and 70000 tonnes of structural steel will be used in the construction. NHSRCL is also preparing detailed project reports for seven high-speed rail corridors. With the experience of implementing the Mumbai-Ahmedabad High Speed Rail project, the work of other corridors will be speeded up.
For the construction of the viaduct superstructure of the 508 km long, Mumbai-Ahmedabad High-Speed Rail Project (MAHSR), state-of-the-art construction methods like Full Span Launching Methodology (FSLM) will be adopted. This technology will expedite the process of launching the girders as the full span precast girders will be erected as a single piece for a double-track viaduct. FSLM is used worldwide because it is faster than the segment by segment launching method, which is commonly adopted for the construction of viaducts for metro rail systems. India is now joining a select group of countries such as Italy, Norway, Korea and China that are designing and manufacturing such devices.
Standard Precast Pre Stressed Concrete (PSC) box girders (weighing 700 to 975 MT) of span of 30, 35 and 45 meters will be launched using FSLM method for high-speed corridor. The heaviest PSC box girder weighing 975 MT and 40 meters in length will be used for the first time in the construction industry in India for the Mumbai-Ahmedabad High Speed Rail project.
to encourage Aatma Nirbhar Bharat Abhiyan Initiative, The 1100MT capacity FSLM equipment has been designed and manufactured by M/s Larsen & Toubro at its manufacturing facility at Kancheepuram, Chennai, for which M/s L&T has partnered with 55 Micro-Small Medium Enterprises (MSMEs).
A total of 20 such launching devices would be required for the construction of a 325-km viaduct superstructure between Vapi and Ahmedabad in the state of Gujarat.
