摘要
广州国际创新城金光东隧道工程沉管段为六节管节的连续设计,针对沉管隧道的防水要求,管段采用防腐底钢板、端钢壳,混凝土表面采用聚脲防水涂料与聚氨酯面漆组成的完整外包防水体系,接缝处根据不同类型采用不同的止水措施,有效保证了沉管隧道的防水效果,为后续管节施工奠定基础。
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.
