When supporting the repair work space of the repair personnel, push the bottom plate 1 through the cooperation of the universal wheel 2 to facilitate the movement of the bottom plate 1, and then adjust the position of the supporting equipment used for shield tunnel segment repair. After moving to the segment repair site, the staff moves to the supporting platform 5 through the ladder 7. The staff is supported by the supporting platform 5 to facilitate the staff to repair the damaged part of the shield tunnel segment. The guardrail 6 can play a certain protective role. The delivery pump 10 will extract and transport the mortar stored in the mortar barrel 8, so that the mortar enters the mortar nozzle 12, and then the staff takes the mortar nozzle. 12 sprays mortar to facilitate repairing the damaged shield tunnel segments, thereby achieving the purpose of repairing and installing the shield tunnel segments. When the support height is adjusted according to different terrains, the servo motor 16 is operated to drive the threaded rod 15 to rotate.

When the support platform 5 moves, it will drive the guide rod 19 to slide inside the guide hole 21. The guide rod 19 cooperates with the guide hole 21 to guide and limit the support platform 5, so that the support platform 5 moves smoothly, thereby achieving the height adjustment of the support platform 5. The purpose of the section is to facilitate the adjustment of different heights so that the operating personnel can repair the damaged parts of the shield tunnel segments. When the height of the support platform 5 is adjusted, the guide rod 19 will drive the driving plate 23 to move through the connecting block 22, and the driving plate 23 will push the compression block 26 to move. When the compression block 26 moves, it will compress the air inside the compression groove 24. After the compressed air inside the compression groove 24 enters the interior of the No. 1 joint 25, it will flow into the interior of the No. 2 joint 29 through the pipeline. The No. 2 joint 29 will make the air flow into the diverter groove 28, and then the diverter groove 28 will make the air flow into the flow groove 30, and the exhaust hole 31 will make the air flow to the interior of the storage rack 27, so that the storage rack can be The repair tools stored inside 27 are cleaned to improve the cleanliness, effectively avoiding the floating objects generated during the shield tunnel segment repair operation from being adsorbed on the repair tools and affecting the repair tools, thus ensuring the cleanliness of the working space to a certain extent. When the supporting area of ​​the support platform 5 is increased according to the operation requirements, the load-bearing plate 36 is pulled to move the load-bearing plate 36 out of the storage groove 35, and then the supporting area of ​​the support platform 5 can be increased through the load-bearing plate 36. After the position of the load-bearing plate 36 is positioned, the support groove 42 is moved to make the support groove 42 move in an arc around the support shaft 41, so that the positioning pin 34 passes through the limiting ring 46, and the position of the support plate 44 is positioned by the No. 2 bolt 43 cooperating with the corresponding No. 2 threaded hole 45.Then, the positioning pin 34, the limiting ring 46, the support plate 44, the support groove 42 and the support shaft 41 cooperate to support one end of the load-bearing plate 36, thereby improving the stability of the load-bearing plate 36, facilitating the increase of the support area of ​​the support platform 5, and expanding the working platform, so as to facilitate the support of the workers in the repair work of the shield tunnel segment.
