BOGIBEEL BIDGE DISTANCE, LENGTH, ALL ABOUT HERE

The mighty Brahmaputra the third largest river in the world and largest in India with the width ranging from 1.2kilometers to 18 kilometers this river is also known as a moving ocean and has been bridged only three times in the past. The Hindustan construction company has a distinction of building two of these three bridges and is now building the fourth bridge at Bogibeel bridge near Dibrugarh. The four-point nine four kilometers long bogie Beale Road commercial bridge will be the third-longest bridge in India and largest over river Brahmaputra this will be the first totally welded steel bridge of IndianRailwaysit is a double-deck the bridge having two railway tracks on a lower deck and three-lane road on the upper deck flanked by footbotson each side for constructing this mammoth bridge,

Etsy CE has set up huge facilities on the south bank of the river that will have three sequences of fabrication assembly and launching the fabrication the shop has 2,000 metric tons per month capacity with two parallelBay's the process begins with the fabrication of different parts which had joined together in the assembly yard to form a truss stacked steel plate relocated by magnetic lifters on platforms are carved using computer software-controlled CNC plasma cutting machine and oxy-fuel cutting machine the edges are altered to match the thickness of the adjoining plate by scalloping and rough edges are beveled using global line machines imported from Canada HCC has assembled customized platforms in-house to fabricate and fit various joints employing gas metal arc welding or gmawand saw welding for ensuring error-free welding die penetration testing ultrasonic testing and magnetic particle testing was deployed by the project team, a specialized be making CMMmachine from Italy is used for the first time in India for the fabrication of box and sections using submerged arc welding or s.a.w procedure blasting gun is used to achieve surface roughness of si two and a half before applying to paint the intermediate and final spray coatings are performed in a highly controlled climatic chamber with spray guns these fabricated sections are then moved to the assembly shop where they are installed on

their designated beds they're guided to their correct positions through jacking and welded by gmaw and s.a.w process these segments are arranged in a sequence and sent for the vertical assembly using horizontal lifters after installation of the top and bottom girders the final truss bridge dimension design chambers are examined thoroughly and approved to complete the fit-out a the nose is fabricated and fitted on the first truss before launching it on the Pires[Music]thousand tons of hydraulic jacks and strand jacks linked with the substructures are used for moving the steel truss over the pillars two sets of steel cable strands are anchored to the end cross beams of the truss and hold by hydraulic jacks[Music]the trust slides over the launchingbearing with the help of sliding plates which are inserted at one end and taken out at the other moving the trust towards its the desired position in order to limit the required launching forces the superstructure is pulled in for launching segments of ten spans each[Music]thus the superstructure is pulled over the pillars just

like a train of 10spans with each span weighing 1700metric tons the pulling force required will be equivalent to pulling 26 Airbusa380s with maximum takeoff weight over650 tons put together without any wheels finally, the lodging bearings are replaced by final bearings the tracks are laid and the road is constructed adopting RCC construction fulfilling the electrical and other ancillary requirements the assignment is completed this rupee 1328 draw project for NorthEast frontier railways is another proof of HCC's immense expertise to accomplish mammoth tasks with utmost ease this bridge will also have strategic importance for ease of transporting troops and supplies to Indian military bases.
