(B) a solid foundation steadily promoting the construction of合同编号:中铁七局集团科研计划项目合 同 书项目名称:时速350km高速铁路客运专线插铺大号码道岔施工技术研究 委托单位:中铁七局集团有限公司承担
13、单位:中铁七局集团郑州工程有限公司起止年限:2011年6月至2011年12月签约日期:2011年 6月20日合 同 书甲方:中铁七局集团有限公司委托乙方:中铁七局集团郑州工程有限公司 研究开发:时速350km高速铁路客运专线插铺大号码道岔施工技术研究项目。根据本集团科技研究开发的有关规定要求,经双方协商,一致同意以下条款: 一、项目的内容和要求1、主要技术要点和关键技术 郑西客运专线新增下行平行渡线工程为郑西客运专线联络线与荥阳南站到发线(3道)连接轨道部分,需要在郑西客运专线下行线插铺一组1/41有碴高速道岔,设计岔心里程为DK22+312.505(K590+467.605),在荥阳南站3道
14、插铺一组1/18有碴高速道岔,设计岔心里程为DK23+360.27(K591+539.87),铺设950米60Kg/m有碴线路连接两组道岔。因郑西客运专线已正式开通运营,新增下行平行渡线工程施工需按既有线进行要点施工。施工期间需要封锁郑西客运专线郑州西站至荥阳南站间下行线路,为保证郑西客专运营正常,上行线正常运营,下行线车辆需逆行上行线,列车按正常速度运行。主要从以下几点进行研究:(1)设计插铺大号码道岔的施工工艺流程,利用网络技术科学安排工期计划,精确计算需要封锁线路时间,使客运专线要点施工做到科学化、合理化。(2)在既有客运专线上,位于高路基段且为电气化铁路的条件下,对大号码道岔构件(转辙
15、器、辙叉、钢轨等)进行装车、运输及卸车的施工方法。(3)客运专线大号码道岔高精度的铺设标准,对底层道砟的摊铺质量及压实度提出了很高的要求,有必要对其施工方法进行深入的研究。(4)大号码道岔铺设的快速定位、组装、捣固、精调;道岔前后与既有线路的顺接和临时接头的防护。(5)快速安装外锁闭装置、转辙机、密贴检查器等部件,转换试验和道岔状态调整。(6)邻线作业,对既有客运专线采取恰当的防护措施,确保郑西客运专线运营安全。研究过程中采用的主要关键技术:(1)由于要与郑西客专正线设置临时隔离网封闭施工,为保证一定的施工区域及安全距离,需将隔离网设置在无碴轨道上。因无碴轨道道床板上不允许打眼固定隔离网立柱,
16、此次施工采用定制的“U”型卡扣连接钢轨和隔离网立柱,将隔离网立柱固定在钢轨上。(2)由于施工场地限制,施工地点无法采用吊装设备卸车。此次施工采用搭设枕木平台,然后逐个抽掉枕木将道岔构件卸车。(3)此次插铺大号吗道岔为有砟道岔,对底层道砟的压实度及平整度要求较高,此次施工采用摊铺机械和夯实机械联合作业,保证底层道砟的铺设质量。(4)在道岔基本到位后,采用可以微调的螺旋杆固定道岔,精调道岔。2、项目要达到的技术指标(1)大号码有砟道岔的铺设质量达到高铁技术标准。(2)总结出一套客运专线插铺大号码有砟道岔的施工工艺。 3、预期成果形态时速350km高速铁路客运专线插铺大号码道岔施工技术研究报告 4、
17、预期经济效益(1)探索要点施工中保证客运专线安全运行的防护措施,减少不必要的设施费用。(2)通过此次研究,优化客运专线插铺大号吗有砟高速道岔铺设工艺,提高施工效率,缩短工期。5、预期社会效益高速道岔是铁路客运专线运营的重要工程结构,其铺设质量直接关系着运营质量和乘坐舒适性。随着越来越多客运专线的建设和开通运营,客运专线之间的相互连接逐渐增多,客运专线插铺大号码道岔施工也会增加。通过此次研究总结出一套完整的客运专线插铺大号码施工工艺,优化既有客运专线施工方案,提高施工效率,减少能耗,为我局以后既有客运专线要点施工积累经验。二、计划进度和阶段目标因本次施工属于客运专线要点施工,具体推进计划排要以铁
18、路局批准的要点计划为准,推进计划具体分为以下几个阶段:1、前期准备阶段(1)结合施工特点编制铁路设备管理单位和郑西客运专线有限公司批准的施工方案及运营安全保证措施。(2)搜集相关资料、规范,咨询有关方面的专家。(3)落实施工研究中需要的设备及仪器,主要为水准仪和CP测量设备。2、科研实施阶段整个要点施工分为轨道施工和道岔铺设施工两部分,重点控制1/41道岔铺设。整个要点施工分三大步进行:第一步:道岔运输、临时隔离网安装、CP测量网设置、既有线路拆除、道岔组装铺设、调整及焊接施工。道岔材料采用火车运输,由荥阳南站(道岔存放地点)经郑西客运专线运送至施工地点,人工卸车。第二步:长钢轨运输铺设。长钢
