Abstract: Aiming at drawbacks of generality, automation, precision of existing installation and positioning method of slide way wellshaped beam, three sets of orthogonal arranged hydraulic cylinders were adopted as power source. Based on results of MGE block and mirrorlike stainless steel plate underwater sliding experimentation, a set of indigenous designed underwater threedirection positioning equipment was developed and applied. Combining hydraulic synchronizing lifting technique and computer communication technology, field experiments on the equipment and the matching construction method were implemented. The results indicate that precisely automatic positioning of wellshaped beam is achieve through this equipment and construction method, which can be used in positioning other similar large concrete structures as well.

 

Key words: wellshaped beam positioning; hydraulic cylinder; MGE blocks
