| Abstract: | The immersed section of Jinguang East Tunnel Project of Guangzhou International Innovation City is a continuous design of six sections. The elements adopt anticorrosive bottom steel plate and steel frame, the concrete surfaces adopt polyurea waterproofing coating and polyurethane top coating, the joints adopt different water-stop measures according to different types, all these effectively ensure waterproofing effect of immersed tunnel and lay the foundation for the subsequent section construction. |
