| Abstract: | The 70 m space box beam with the dead weight ton of 2200 for the over-sea bridge are difficulty for fabrication, transport and erection.. The double-trestle jetty of pre-casting yard is the key point for box beam sea land transit. Being as the large and temperate facility of the bridge construction, the structures of PHC pipe pile foundation of pre-stressed concrete, reinforcement concrete bearing platform and reinforcement slipway are adopted in the design. Which has successivly solven the difficult problem of land carrying and sea transportation of super large and heavy precast box beam. |
