Abstract:

The application range and characteristics of rubber waterstopping tie are presented. Construction sequence and installation requirements of radial and longitudinal waterstopping ties are presented. The connection and installation of stopping ties are solved by using steel Ushape block and wood block frame to fasten waterstopping ties and adopting rational connection mode. The paper can provide references for waterstopping tie construction of similar projects in the future.
