Description

technical field [0001] The invention relates to an underwater high-precision measurement and control system and a measurement and control method for butt jointing of pipe sections in the construction of immersed tube tunnels. Background technique [0002] Since many works of immersed tube tunnels are carried out underwater, compared with land tunnels, immersed tube tunnels have higher requirements for survey work. For the construction of immersed tube tunnels, how to measure and control the immersed tube is a worldwide problem. After years of research and technology accumulation on immersed tube tunnels, developed countries have already had relatively mature solutions to these problems. [0003] Due to the relatively late start of research on the measurement technology of immersed tube tunnels in my country, there are relatively few technologies, experiences and reference materials in domestic research, and there is almost no system for the measurement and control methods a...
