中文摘要 | 現今軌道之道床構造可區分為道碴式及無道碴式兩種,傳統道碴道床式軌道,具 有初期建造費用較低、施工迅速,施工完成後容易再次調整線型等優點,但因道碴材料日漸 枯竭,完成後之維修工作量大,故在台北捷運高運量路線的規劃中,除淡水線地面段及各維 修機廠使用道碴道床之外,其餘各主線都採用效益高、維修費低之無道碴道床系統。目前全 世界無道碴道床之施作方式可概分為現場澆置式、預鑄式及複合式三種,台灣地區除台鐵曾 試行引進日本預鑄版式系統之外,大部分皆採現場澆置式施作。無道碴道床現場澆置之方式 ,又因扣件施作組裝程序之不同,區分成由上而下施工法與由下而上施工法,本研究係利用 價值工程之研析方法針對本局現今所使用之混凝土軌道基座施作方法進行比較,由結果顯示 由上而下施工法之生產力,若能進行些許改變則其效益明顯高於由下而上施工法。 |
英文摘要 | There are two different plinth construction method today, i. e. ballasted and direct fixation fastener (DEF) system. The benefits of conventional ballasted construction are low cost and faster at constructing, and ease to adust track alignment after completion. As the maintenance work become more and more demanded, the ballast's materials become increasingly rare. Therefore, ballasted systems are only adapted in plain sections and depots of Taipei MRT, DFF systems (which are low maintenance cost efficient) areused in rest of the main track ways. There is job - site concreting, pre - casting, and complex type, threedifferent kinds for concreting plinths in the world today. Job - site concretingis the major construction method performed in Taiwan. However, Japan'spre - casting method was used by TRA as well. Based on the different clip installation procedures, the details of completed DFF system could be divided into Top - Down and Bottom - Up methods. This research is using VE to compare the mean s in concreting linthsfrom DORT's projects in Taipei. The results reflect that after improving the Top - Down construction, the productivity of Top - Down method will havehigher efficient rate than Bottom - Up method. |
