【摘要】 为控制公路隧道的渗漏,结合工程实践研究了公路隧道的防渗漏问题,提出防渗漏工作应贯穿于隧道施工全过程的思路。给出施工过程中防渗漏环节的质量控制方法,重点介绍CPE防水板、排水管、纵向排水盲沟的施工要点及高抗渗耐蚀二次衬砌混凝土的应用。研究结果表明,公路隧道的防渗漏工作,应该向前扩展至铺设防水层之前的开挖和初期支护阶段,向后延伸至二次衬砌阶段。更多还原

【Abstract】 This paper studies the seepage prevention in highway tunnel with the experience.It is pointed out that the measures of defending seepage in highway tunnel should be applied to the overall construction of tunnel.The results of study show that the work of defending seepage in highway tunnel should be expanded to the stage of excavation and initial protective support before paving waterproof layer,and extended to the secondary lining stage.The quality control methods of defending seepage,such as CPE waterproof board,drain pipe,longitudinal blind drain,and the application of high impervious anticorrosion secondary lining concrete,are introduced.2 figs,6 refs.更多还原
