AI Technical Summary
In the existing technology, the backfill trench treatment is not thorough, which affects the laying quality and interface bonding strength of the new lining slab, making the repaired lining slab prone to secondary defects such as hollowing and loosening.
An underwater lining slab repair construction equipment was designed, including a truss, a beam, and a slab extraction mechanism, a waste material cleaning mechanism, and a backfill trench leveling mechanism integrated on the beam. The automated system completes the process of extracting large pieces of waste material, cleaning small debris, and flattening the base surface.
This improved the continuity and overall efficiency of construction, ensured the quality of the new lining slab laying, reduced the safety risks of underwater operations, and prevented the occurrence of secondary defects after repair.
