AI Technical Summary
In existing technologies, the sealing materials at expansion joints are easily damaged, and traditional drainage designs are easily compromised, leading to potential leakage risks. Furthermore, existing water guiding devices have simple structures and poor adaptability, making it difficult to achieve efficient drainage and long-term sealing under dynamic deformation conditions.
It employs a V-shaped guide channel, a retractable connecting cylinder, an expansion component, and a linkage mechanism, combined with a waterstop, to achieve sealing and drainage under dynamic deformation. Through the sealing of the expansion component and the airflow-assisted drainage, it adapts to complex deformations and enhances the sealing effect and drainage rate.
It improves the reliability of building waterproofing, extends the service life of the structure, reduces maintenance costs, enhances environmental adaptability and drainage efficiency, and prevents leakage and foreign object accumulation.
