Description

technical field

[0001] The invention belongs to the field of measurement and control of immersed tubes, and in particular relates to an integrated measurement and control system and a measurement and control method for floating installation of immersed tubes in open sea. Background technique

[0002] The traditional underwater positioning measurement methods for immersed tube installation at home and abroad mainly include absolute positioning method and relative positioning method. The absolute positioning method includes the total station method and the GPS-RTK method, and the relative positioning method includes the sonar method and the mechanical pull wire method. However, with the advancement of science and technology and the acceleration of the modernization process, the installation of large-scale immersed tube tunnels is gradually developing towards the open sea and deep water, and the construction technology is gradually optimized. The basic measurement method for un...
