Abstract

Abstract:

为解决液化天然气（LNG）接收站LNG工艺隧道的高标准防水问题，在新奥法建造的LNG工艺隧道中采用包含喷膜防水层的复合防水层体系。基于运营过程中安全环保的考虑，LNG工艺隧道的防水标准比常规隧道更为严格。通过比较几种可能的防水方案，设计了包括径向灌浆、排水系统、EVA防水板、丙烯酸盐喷膜防水层以及其它防排水设施的双层防水系统。通过实际施工结果和后续的观察，该隧道的防水实施效果良好。本隧道中喷膜防水技术成功应用的重点在于：合理设计的防水系统、喷膜防水层的性能、施工人员技术培训、充分的准备工作，认真执行和完善的质量控制和验收。丙烯酸盐喷膜防水技术与其他防排水措施相结合的成功运用，为达到类似高标准隧道的防水质量提供了解决方案。
