Strand Jack Lifting method

The 875m-long part of the truss bridge was constructed using the strand jack lifting method. The large truss block whose length was equal to the span length was fabricated at the shop near the site. The block of theintermediate support was first separated using a 2000t floating crane. The rest of the span was shipped on the 10000t barge using a tidal difference. The barge was pulled into the jetty at low tide and, as the tide level rose, the span was automatically shipped on the barge. After shipping, the loaded barge was tugged out of the jetty and pulled into the site. At high tide, the barge was pulled into the space between the piers. As the tide level fallen, the transported span was placed on the temporary support that was installed on the pier foundation. Lifting was performed after the lifting post was connected to the truss and the strand jacks were installed. The lifted large block and the small block were connected and the placement of the block was adjusted using the hydraulic jacks placed on the pier top.
