| Abstract: | The high pressured inflatable rubber airbag, a new kind of sealing material, has been applied to shield tunneling. The sealing principle, properties, structural characteristics, selection and design and installation process of high pressured inflatable rubber airbag are introduced and analyzed. The analytical results show that the tunnel entrance/exit and shield shell can be effectively sealed by high pressured inflatable rubber airbag, and compared to traditional materials, the high pressured inflatable rubber airbag is more rational and functional. |
