They are responsible for resisting soil pressure, groundwater pressure and some special loads. Tunnel segments are the permanent lining structure of shield tunnels. The quality of tunnel segments is directly related to the overall quality and safety of the tunnel, and affects the waterproof and durability of the tunnel. Tunnel segments are usually produced using high-strength impermeable concrete to ensure reliable bearing and waterproof performance. The production mainly uses finished segment molds that can be formed after sealing and pouring concrete.
[0003] Before installing the tunnel segments, the segments need to be transported into the tunnel, and then carried by a transport device for moving and placement. The transport device fixes the segments by clamping them. The segments will swing when lifted and moved.

[0024] The linkage frame 8 connected by the telescopic rod 7 is provided with a first top seat 21 and a second top seat 22, and the first top seat 21 and the second top seat 22 are arranged vertically on the linkage frame 8.

[0029] like Figure 1-7 As shown, a method for using a segment installation device for shield tunnel repair comprises the following steps: S1: When installing the pipe segment, first move the rail car 2 to the pipe segment position, align the cross frame 4 of the rail car 2 with the pipe segment, lift the pipe segment and move the clamp 6 on the cross frame 4, and plug the clamp 6 into the connecting end of the pipe segment. During the movement, the pipe segment is vacated, and the clamp 6 is driven by the pipe segment to move downward. When the clamp 6 moves downward, it will drive the connected telescopic rod 7 to move downward, and the linkage frame 8 connected to the telescopic rod 7 will move to the position of the slide seat 14; S2: The first top seat 21 and the second top seat 22 are installed on the linkage frame 8. When the linkage frame 8 moves downward as a whole, the first top seat 21 and the second top seat 22 will push the corresponding slide 14, and the slide 14 will move due to the pushing of the first top seat 21 and the second top seat 22. When the slide 14 moves, it will drive the top frame 13 to move along the stabilizing frame 9. When the top frame 13 moves horizontally, the vertical position will not change. When the stabilizing frame 9 is pushed by the top frame 13, it will rotate downward. The surrounding stabilizing frames 9 will overlap the pipe segment body 3. The stabilizing frames 9 will limit the pipe segment body 3 in four directions, and the pipe segment body 3 will not shake during the movement.
[0030] Working principle: by installing the cross frame 4 on the rail car 2, the telescopic rod 7 can be installed on the cross frame 4. When one end of the telescopic rod 7 is connected to the clamp 6, the clamp 6 can fix the segment body 3. When the cross frame 4 moves with the rail car 2, the segment can be carried for installation. After the clamp 6 is connected to the segment body 3, it starts to move. During the movement, the segment body 3 is in a vacant state, and the telescopic rod 7 will move downward due to the weight of the segment body 3. When the telescopic rod 7 moves downward, the first top seat 21 and the second top seat 22 will push the slide 14 to move. After the slide 14 is pushed, it will drive the top frame 13 to push the stabilizing frame 9 down, and the stabilizing frame 9 will be overlapped on the segment body 3. The stabilizing frame 9 will support the four directions of the segment body 3, and the segment body 3 will not shake during transportation and installation, thereby preventing injuries to the staff.
