Problems solved by technology
At the same time, the strength, deformation characteristics, waterproof, materials and detailed structure of the joint should also be considered. However, during the installation process of the joint, there are often installation misalignments, etc., and the installation state of the joint cannot be detected, resulting in the joint being easily damaged during the installation process.
[0004] Through the above analysis, the existing problems and defects of the prior art are as follows: the installation status of the joint cannot be accurately detected during the installation process of the existing final pipe joint, resulting in damage to the joint during the installation process

The invention belongs to the technical field of tunnel construction, and discloses a final joint system and method of an immersed tube tunnel and a final joint. The final joint system of the immersed tube tunnel includes: an obstacle avoidance module, an image acquisition module, a final takeover height detection module, a final takeover descent speed detection module, a final takeover state detection module, a display module, a central processing module, a signal transmission module, and a mobile terminal , crane control module, jack adjustment module, alarm module, and finally take over the left and right movement detection module. The invention can accurately detect the installation state of the final connection during the installation process of the final connection, thereby improving the installation accuracy of the final connection and improving work efficiency. At the same time, the present invention is connected with the mobile terminal through the signal transmission module to realize the control and remote monitoring of the final takeover and installation process, and can monitor and control remotely.
Description
technical field [0001] The invention belongs to the technical field of tunnel construction, and in particular relates to a final joint system and method of an immersed tube tunnel and a final joint. Background technique [0002] At present, in the installation of the pipe section of the immersed tube tunnel, in order to make the last section of the pipe section be placed smoothly, a space longer than the distance of the pipe section must be reserved. After the last pipe section is lowered, the end surface of the last pipe section needs to be connected with the previous pipe section through a connection structure, which is the final joint. [0003] The final joint design and processing technology of immersed tunnel is one of the key technologies of immersed tunnel. The joints should be designed to withstand temperature changes, seismic forces and other effects, and ensure good watertightness. Each pipe section of the immersed tube tunnel is a prefabricated part, and there a...
