High-pressure inflatable pipe plugs offer a faster, safer, and more cost-effective alternative. Engineered for durability and high performance, these plugs are inserted into the pipeline and inflated to create a secure, temporary seal against internal pressure.

Therefore, damping and seismic isolation technology emerged, mitigating the impact of earthquakes on building structures by isolating or dissipating seismic energy. This paper focuses on the application of damping and seismic isolation technology in building seismic retrofitting and its construction optimization measures.

the time required to replace an expansion joint typically ranges from several days to several weeks. Such maintenance operations often result in significant traffic congestion and lane closures. Therefore, it is necessary to explore technical methods can accelerate the replacement process.
