文档介绍：成都地铁盾构设备配置王国义(中铁十三局集团有限公司,长春 130000 ) 摘要:成都地质条件以高富水、高卵砾石含量著称,何种配置的盾构更能适合成都这种地质,一直是大家争论的焦点。根据成都地铁 1号线一期工程 4个盾构标段存在刀盘消耗成本大、换刀困难、地表易坍塌及刀盘和螺旋输送机磨损严重等实际问题,分析盾构设备的优缺点,提出将刀盘的开口率增大、螺旋输送机由轴式改变为带式、对卵石的处理方式由破碎为主变为排出为主,可以大大降低刀具成本,同时刀盘和前盾进行适当改动,解决换刀困难和地表易坍塌的问题。更改后的盾构设备配置更适合成都地铁盾构施工。关键词:成都地铁;盾构;设备配置;刀盘中图分类号: 文献标志码:B 文章编号:1672-741X (2008 )04-0501-04 ShieldEquipmentDispositionforChengduMetro WANGGuoyi (13 ,Changchun130000 ,China ) Abstract:,thetopic thatwhatkindofshieldissuitableforChengdu’ structionofthe4shield2 boredtunnelcontractsectionsonPhase1projectofLine1ofChengduMetro,problemssuchas highcutterheadconsumptioncost,beingdifficulttoreplacethecuttingtools,thegroundsurfacebeingsubjecttocol2 gesoftheshieldequipmentandcountermeasures,suchasincreasingthecutterhead’ sopeningratio,shiftingthescrew conveyorfromshaft2 typescrewconveyertobelt2 typeoneandtreatingthegravelfrombreakingprimarilytodischarging primarily,,propermodificationismadeonthecutter modifiedshieldsaremoresuitablefortheconstructio
