文档介绍：:..浅谈铁路隧道防排水施工摘要:目前山岭重丘区铁路建设项目屮隧道工程所占的比例越来越大。隧道所处地区的工程地质及水文情况影响着隧道的施工进度、工程质量、施工安全及运营,而水又是影响隧道正常施工、正常运营的重要因素。在施工期间,防排水施工往往得不到施工单位的足够重视,从而导致隧道完工后地下水常常自衬砌及仰拱施工缝、变形缝、裂缝及混凝土孔隙中渗入隧道,造成洞内通信、供电、照明等设备处于潮湿环境而发生锈蚀,使路面积水或结冰,危及行车安全。因此做好铁路隧道工程的防排水施工意义重大。本文首先分析了铁路隧道渗漏水的危害,然后阐述了铁路隧道防排水施工的总体思路,最后重点探讨了铁路隧道防排水施工技术要点。关键词:铁路隧道;防排水;防水板;排水盲管;焊接Abstract:atpresentthemountainshighturrnelengineeringinrailwayconstructionprojectstheproportionismoreandmorebig・Tunnelengineeringgeologicalandhydrologicalconditionsaffecttheareaofthetunnelconstructionprogressandconstructionquality,constructionsafetyandoperation,,waterproofanddrainageconstructionunitconstructionisoftennotenoughattention,pletionoftheturmelgroundwateroftensincetheliningandinvertedarchconstructionjoints,deformationjoints,cracksinconcreteporeandintunnels,munications,urs,thesurfacewateroricethatendangerssafety・,thenexpoundstheoverallplanofrailwaytunnelwaterproofanddrainageconstruction,finallydiscussedtherailwaytunnelwaterproofanddrainageconstructiontechnologykeypoints・Keywords:railwaytunnel;Waterproofanddrainage;Waterproofplate;Drainagetube;Thewelding中图分类号:U455文献标识码:A文章编号:
