【正文】 移交一段～施工一段～多段移交～多段施工～配齊人力、物力、財力等資源～見縫插針～精心施工。 ,6,制訂行車事故應(yīng)急預(yù)案 制訂行車事故應(yīng)急預(yù)案～一旦發(fā)生安全事故～應(yīng)嚴(yán)格按照事故處理流程逐級上報～并立即組織人員進(jìn)行搶險救援～消除或控制險情～防止事故蔓延～將損失減小到最低程度。精心組織～在“請點”時間范圍內(nèi)完成所需的工作內(nèi)容。 無縫線路鎖定施工～必須配足施工人員和施工設(shè)備～縮短無縫線路鎖定的時間～確保鎖定施工期間的溫差不超過設(shè)計的允許范圍。 ,2,采用“散鋪支架法”施工工藝～精確鋪設(shè)道岔及渡線 道岔鋪設(shè)擬采用“散鋪支架法”施工～即現(xiàn)場散鋪道岔～采用專門設(shè)計的道岔支承架架軌～調(diào)整道岔幾何尺寸及平面位臵～綁扎及焊接道床鋼筋～精調(diào)道岔狀態(tài)～澆筑道床鋼筋混凝土。 3工程重點、難點及對策 1,工程分析 ～該道床結(jié)構(gòu)比較復(fù)雜～施工精度要求高～施工周期長。 ,6,軌枕鋪設(shè)標(biāo)準(zhǔn): 出入線地下段軌枕按1680對/km布臵～軌枕間距為595mm。 2,停車場軌道 ,1,出入線采用60kg/m鋼軌,U75V,。 ,4,采用鋼筋混凝土短軌枕式整體道床～軌道結(jié)構(gòu)高度為:地下線圓形隧道:非鋼彈簧浮臵板道床地段為760mm～鋼彈簧浮臵板地段為820mm,地下線馬蹄形隧道:,560+f,mm～f 為軌道結(jié)構(gòu)底部至隧道底部的矢高,地下線區(qū)間矩形隧道:560mm,一般車站矩形隧道:560mm,換乘車站及重點車站矩形隧道:600mm。 2,水文氣象條件 鄭州地區(qū)屬暖溫帶季風(fēng)氣候～四季分明～? 。 設(shè)計列車行車最高速度為80km/h。 場、段、控制中心均已在一期工程實施～二期工程僅在雪松路站西端增加一條出入線連接凱旋路停車場。 4,合理安排施工順序～抓住重點～突出難點～組織專業(yè)化施工～保證各項施工工序相互促進(jìn)～緊密銜接～促進(jìn)工程高效、均衡～加快施工進(jìn)度。軌道交通鋪軌安裝工程實施性施工組織設(shè)計作者：日期：鄭州軌道交通1號線二期鋪軌安裝工程實施性施工組織設(shè)計目錄1編制依據(jù)、原則及相關(guān)標(biāo)準(zhǔn)
