Device and method for disconnecting pipe joints
The invention relates to the technical field of installation of a seabed immersed tube tunnel, and provides a device and a method for disconnecting pipe joints. The device comprises rotating beams, wherein horizontal fixing supports are fixedly arranged on the rotating beams and are provided with multiple jacks; when the rotating beams are positioned in horizontal positions, the positions of the pushing jacks correspond to a concrete pipe rack at the bottom part of the device, the jacks are distributed along the horizontal direction of the concrete pipe rack, the end surfaces of the jacks are uniformly stressed, and thus GINA water stop belts are enabled not to roll over and an end steel shell and steel diaphragms are enabled not to be affected during a jacking and disconnecting process of adjacent pipe joints; in addition, when the rotating beams are rotated to vertical positions, the whole device for disconnecting the pipe joints is positioned in a joint cavity, the butt joint work of the pipe joints in the next time cannot be affected, thus repeated use can be carried out until accurate butt joint is carried out on the pipe joints. The device disclosed by the invention is simple in structure, clear in stress, convenient to design and manufacture and capable of enriching the installation technology of an immersed tube tunnel to a large extent when being applied to a refloating pre-arranged plan of the seabed immersed tube tunnel.
