    CA - Oresund Bridge

    Uploaded by

    Apoorva Singh
    The document discusses the Oresund Bridge project which connects Sweden and Denmark. It describes the various design options that were considered, including an underwater tunnel, artificial island, or bridge. An artificial island and a combination bridge-tunnel design were ultimately selected. The construction of the project involved building the artificial island, sinking underwater tunnel segments, and using innovative techniques like cantilever construction to build the bridge portions.

    THE UNDERWATER TUNNEL

    This was filled till the water level reaches the sea
    level

    Reinforcement Cage for constructing tunnels which are


    put in a mould

    To make the segments reach water, they


    were kept on edge which was then filled
    with water

    Once the segments start floating properly, they were


    taken to site
    Concrete poured in the mould forming
    the tunnel segments

    Tunnel segments sealed at ends to make them


    float in water

    CONSTRUCTION
    THE UNDERWATER TUNNEL

    To make them sink in balance horizontally, the


    segments were filled with water and cables were
    used to place them accurately

    The tunnels after being placed and fixed, were covered


    with 1 M of concrete after sucking the water out to stop
    them from floating in water
    The top of the tunnel was covered with boulders to
    keep it from floating
