Abstract: Several commonly used treatment methods and materials for crack repair in a certain city's water supply channel engineering were analyzed and studied. Four typical disease areas were selected from two typical structures,which are the north and south sides of the exposed box culvert in the A inverted rainbow gradient section, and the east and west sides of the B aqueduct box. Under the condition of continuous water supply, different reinforcement and anti-seepage materials and construction techniques were used to reinforce the damaged areas caused by construction cold joints on the north and south sides of the exposed box culvert in the A inverted rainbow transition section, including concrete deterioration, structural water seepage, large-scale swelling, peeling, seepage of concrete skin, local yellow white crystal precipitation, and long cracks, water seepage, and local crystal precipitation on the east and west sides of the B aqueduct box. At the same time, combined with the on-site treatment effect, a comparative analysis and study of the reinforcement materials and construction techniques used were conducted to obtain the optimal solution suitable for different diseases, providing scientific and rational suggestions for later management work, and providing reference for the treatment of similar water conservancy facility diseases.
