Method for precisely positioning a prefabricated structure by sinking into the sea or into a river, and maritime or fluvial construction obtained by said method

摘要

this process is at least partially prefabricated structure with a floating caisson (1), (2) while leaving a set of several metres from the vessel (1) and the structure (2), and when the chamber formed by the floating structure (1) and (2) find at the site where the structure is washed up.to set a position and a direction to approximate the appropriate box to fail (2) on the bottom (11) of ballast, and fail the structure (1) with a position and an orientation of the specific substance (11), so that it sinks in the structure (1) and using the the chamber (2) failed as a fixed point for positioning and orientation of the structure (1).this process can be used for the grounding for a foundation for a bridge pier, and it also makes possible a fabrication and assembly on the ground or in a port of the superstructure of the bridge deck, cable-stayed pu00eele, tower) by shifting it provisionally by the box (2).
