AI Technical Summary

Technical Problem

During the sinking and docking process of composite cylindrical foundation components, the actual size and design size difference due to production errors, resulting in the positioning system showing that the composite cylindrical foundation components have been implanted but have not been implanted or have not implanted, which affects the safety of sinking and may damage the submarine gravel foundation bed.

Method used

By conducting overall observation of the top and bottom elevations of the composite cylindrical foundation member, calculate the actual height, correct the bottom elevation in the design positioning parameters, and adjust the sinking and placement attitude using the corrected parameters until the bed is safe and stable.

Benefits of technology

It realizes precise control of the sinking and placement attitude of the composite cylindrical foundation components, ensures its accurate, safe and stable sinking foundation bed, lays the foundation for high-precision docking of the composite cylindrical foundation components of the marine protective structure, and ensures the service life of the protective structure project.

Abstract

According to the sinking positioning and attitude control method and device for the composite barrel type foundation component and the medium, it can be guaranteed that the composite barrel type foundation component is accurately, safely and stably sunk into a foundation bed, a foundation is laid for high-precision butt joint of the composite barrel type foundation component of a maritime work protection structure, meanwhile, the engineering design service life of the protection structure is guaranteed, and the construction cost is reduced. The method includes the steps that before underwater sinking, overall observation is conducted on the top face elevation and the bottom face elevation of the composite barrel type foundation component, and comprehensive observation data are obtained; based on the comprehensive observation data, the actual height of the composite barrel type foundation component is calculated; based on the actual height, correcting the bottom elevation in the design positioning parameters of the composite cylindrical foundation component on the design picture album; taking the design positioning parameter after the bottom elevation is corrected as a sinking design elevation, and inputting the sinking design elevation into a sinking positioning system; and in the sinking process, a sinking positioning system is called to adjust the sinking posture of the composite barrel-shaped foundation component based on the sinking design elevation until the composite barrel-shaped foundation component is safely and stably implanted.
