    Background<\/h2><\/div>

    Bangalore International Airport (BIAL) is located in Devanahalli, 34 KM from CBD on NH-07. Due to the rapid growth of its IT sector, Bengaluru needed a world class airport for its customers, so the government of Karanataka planned to build new airport at Devanahalli.<\/p>\n

    It was necessary to build a Trumpet interchange to provide access for vehicles commuting from Bengaluru as well as Hyderabad to cross NH-07. Apart from major road like NH-07, an additional Road Over Bridge (ROB) and a Vehicular Underpass (VUP) needed to be built.<\/p>\n

    BIAL awarded the project to L&T Ltd. The Trumpet interchange had a major flyover merged with ROB, two ROBs and a VUP to provide signal free access for vehicles from both Bengaluru and Hyderabad, without affecting entry for adjacent villages.<\/p>\n<\/div><\/div><\/div>

    <\/span><\/div>

    Challenge<\/h2><\/div>

    Designing the Reinforced Earth\u00ae wall needed many details with respect to overlapping of ramps, close proximity of ROBs and diagonal ramps.<\/p>\n

    At CH 1+120, a flyover on NH-07 needed to be merged with an ROB. At the same location, all 3 ROBs would converge and have a single ramp with a closing wall of 150m length. Also at the ROB location, the height of wall would be 15m.<\/p>\n

    Time was a major challenge, too, as L&T Ltd wanted to complete the entire project in five months. Terre Arm\u00e9e in India worked 24 x 7 to achieve the deadline. The project not only tested Terre Arm\u00e9e\u2019s design and construction abilities, but also tested its supply chain with its massive requirement of materials in a short span of time.<\/p>\n<\/div><\/div><\/div>

    <\/span><\/div>

    Solution<\/h2><\/div>

    In a detailed design process, Terre Arm\u00e9e in India used in-house technical know-how to design the Reinforced Earth\u00ae wall using High Adherence (HA™) Galvanized Steel Strips as soil reinforcing elements with well graded fill material having angle of internal friction (\u0424) > 32\u00ba and considering normal traffic surcharge for the design as per IRC 6.<\/p>\n

    Terre Arm\u00e9e in India successfully designed the structure considering all the requirements of the client.
    \nTerre Arm\u00e9e in India supplied enough moulds, keeping the tight construction period in mind, to produce precast panels well in advance.<\/p>\n

    The entire construction of the 39,300 sq m Reinforced Earth\u00ae wall was completed in the stipulated in five months without any cause for complaint or safety lapse.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/p>\n","protected":false},"excerpt":{"rendered":"
