Abstract
The design and construction of railway tunnel waterproofing and drainage have been puzzling the builders of railway tunnels due to the difficulties in realizing the perfect design of waterproofing and drainage under current construction technical conditions,which often results in leakage of various degrees in some underground-water-development tunnels. With reference to the design, field construction and leakage remedies after operation and based on the analysis of waterproof and drainage of the surrounding rock,primary support,inverted arch, construction joint, the design and construction of the drain board,and the causes of the ballastless track uplift,this paper proposes such waterproofing and drainage measures as canceling the non-woven fabric wrapped on the longitudinal blind tube behind the lining of the liner, the provision of the drainage board with nail shooting or self-adhered construction technology,and the enhancement of waterproof and drainage measures by ballastless track inverted arch and grouting with mold.关键词
