Title:

INTELLIGENT CONTROL METHOD FOR POSITIONING AND SETTLING OF DEEPWATER PREFABRICATED FOUNDATION OF LARGE BRIDGE

Document Type and Number:

WIPO Patent Application WO/2024/124440

Kind Code:

A1

Abstract:

The present disclosure relates to an intelligent control method for positioning and settling of a deepwater prefabricated foundation of a large bridge. The upper portion of a prefabricated foundation is located above a water surface, and the lower portion of the prefabricated foundation is located below the water surface; I positioning devices are mounted at the top surface of the prefabricated foundation, J positioning ships are arranged around the prefabricated foundation, I is a natural number greater than or equal to 3, and J is a natural number greater than or equal to 4; the positioning ships are connected to the prefabricated foundation by means of mooring hawsers. The method comprises: by using an equation of motion of the settling process of a prefabricated foundation under the coupling effect of wind, waves, and currents, an intelligent regulation and control center performs intelligent control on the motion posture of the prefabricated foundation by means of mooring hawsers. According to the present disclosure, by using an equation of motion of the settling process of a prefabricated foundation under the coupling effect of wind, waves, and currents, and the intelligent regulation and control center performs intelligent control on the motion posture of the prefabricated foundation by means of mooring hawsers, thereby greatly improving the precision, robustness, efficiency, and safety of positioning and settling of deepwater prefabricated foundations.
