PROCESS FOR THE PRECISION POSITIONING BY STRANDING, AT SEA OR RIVER, OF A PREFABRICATED STRUCTURE, AND MARITIME OR RIVER WORK OBTAINED BY SAID PROCESS.

摘要

P This process consists in at least partially surrounding the prefabricated structure 1 by a floating box 2, while leaving a clearance of several meters between the box and the structure, then, when the floating assembly formed by the box and by the structure is at the site where the structure is to be stranded, to give said assembly a suitable approximate position and orientation, then to strand the box on the bottom by ballasting, and to strand the structure with a precise position and orientation on the bottom , by ballasting said structure and using the stranded box as a fixed point for positioning and orientation of the structure. This process can be used for the precise grounding of a foundation for a bridge pier, and it also makes possible prefabrication and assembly on land or in a port of the bridge superstructure (pier, pylon, deck, stay cables) by temporarily supporting it by the box.
