Design and Application of Curved Pipe Jacking Launchers
As an important part of the integral salvage “Yangtze River Estuary II”, several curved beam sections had to be jacked through the soil around the wreck to form a bottom bracket to wrap the wreck. The curved beam sections are different in structure, construction method, and guidance from the traditi...

| description | As an important part of the integral salvage “Yangtze River Estuary II”, several curved beam sections had to be jacked through the soil around the wreck to form a bottom bracket to wrap the wreck. The curved beam sections are different in structure, construction method, and guidance from the traditional linear bottom brackets in integral salvage. Therefore, special construction equipment had to be developed and used. The curved pipe jacking launcher, as a special device for jacking through curved beam pipe joints, has successfully completed the salvage of “Yangtze River Estuary II” after preliminary scaled-down model demonstration, design and manufacture, isometric test and re-optimisation design and manufacture. The design and the application of the method can be applied to offshore salvage and in-situ protection of the foundation of the ancient relics. |
