Connecting the Length and Breadth of Metro Rail in India

transportation system

Indian cities are among the world’s fastest developing cities in terms of infrastructure, economy, and even population, which calls for a better transportation system. The transportation system of India is slowing taking a pragmatic shift to Metros. Kolkata was the first city to get rapid transit system in India, put in motion almost 25 years ago. Chennai is the second city in India to run a rapid transit system in 1995, Chennai Mass Rapid Transit System is an elevated railway line running within the city. Followed by Delhi Metro rail running across the national capital region. Currently metro rail projects are running in various parts of the country. After the success of the Delhi metro, 26 cities in the country are at various stages of planning and implementing the metro rail.

Schwing Stetter at Metro Projects

Concreting is one of the major work in metro construction, Schwing Stetter ranges of concrete equipment are used for concreting the metros across India.

Majority of construction work in metro project are differentiated into Elevated Corridor Structures, Elevated Railway Stations, Underground Tunnel Construction, Underground Railway Station, and Underground to elevated Interlinking junctions.

Metro Elevated corridors (Viaduct) are meticulously designed structures developed with immaculate understanding of high strength concrete. The elevated structures consist of precast segment made using special type of concrete.

The State-of-the art construction method helps to make Pre-cast Pre-stressed concrete segments. These segments are of different types like Box Girder Segment, Spine, Wings, Single Segmental U, Single Segmental Box, Segmental Box, Segmental U, Full U girder, Pre-cast pre-stress I girders, Cast in Situ Span, and Special span.



These pre-casted segments are prepared by casting concrete in reusable molds in a controlled environment. Then it is transported to construction site and set in place. Some of the pre-cast structures used in elevated metro stations are Platform sections, Precast post-tensioned cross girders and Pre-cast post-tensioned L-beams.

The elevated corridor also requires concrete pile cap, pier and cross heads (cast in situ/pre cast pier heads). Schwing Stetter’s Batching Plants like CP30 and M1 are used for per-casting various segments for the elevated corridors. Schwing truck mounted boom pumps like S20, S36 are used for concreting the pile cap, pier and cross heads. Underground Tunnel Construction is carried out using Tunnel Boring Machines (TBM) which not only excavates the tunnel but also installs precast concrete liners (tunnel rings). As the machine advances its movement drilling, pre-cast concrete tunnel liners are installed.

The pre-casted tunnel rings are also made of special type of concrete which are designed to withhold various types of loads. Schwing Stetter Concrete Trailer pumps are used to concrete the floor inside the tunnel to lay tracks for metro trains. Underground Metro Stations are constructed using massive amount of concrete in which Schwing contribution is enormous.

Underground Stations are constructed using cut-and-cover methods in two different ways “top-down” or “bottoms-up” approach. For the underground stations, diaphragm walls and plunge columns are constructed to ensure that soil does not collapse on the edges as the excavation progresses.

The construction of the diaphragm wall is carried out from ground level using special type of concrete; Schwing Stetter Transit Mixers are employed to transport concrete for the construction of these walls.
