Title:
UNDERWATER MOUNTING POSITIONING SYSTEM AND METHOD FOR FINAL JOINT IN IMMERSED TUBE TUNNEL
Document Type and Number:
WIPO Patent Application WO/2024/017408
Kind Code:
A1
Abstract:
The present application belongs to the technical field of immersed tube tunnel construction, and particularly relates to an underwater mounting positioning system and method for a final joint in an immersed tube tunnel. The positioning system comprises at least two underwater positioning devices arranged on the final joint, and at least two underwater positioning targets arranged on tube sections to be aligned, wherein each underwater positioning device comprises a camera displacement meter and a cable displacement meter, which are combined in the same instrument box; and a data processing terminal is in communication connection with both of the camera displacement meter and the cable displacement meter by means of a serial port server, so as to obtain measured data in real time and further calculate real-time plane displacement and angle of rotation of the final joint. With the underwater mounting positioning system for a final joint in an immersed tube tunnel of the present application, the plane displacement and the angle of rotation of the final joint during pushing of the final joint can be accurately monitored to position the final joint and determine the pose of the final joint with high precision, and the accuracy and reliability of mounting construction of the final joint is better ensured.
