At present, steel wire ropes are used to pass through the inner wall of the pipes for binding and connection before lifting the concrete drainage pipes. Since the drainage pipes are heavy, friction between the steel wire ropes and the drainage pipes is generated during lifting, resulting in damage to the drainage pipe openings each time they are lifted, which has a significant impact on the construction quality. In addition, multiple people are required to assist in fixing during installation, which increases the workload. Therefore, specific lifting tools are required to lift and lay the concrete drainage pipes. Summary of the invention
