有砟高速道岔铺设新技术

摘要

研究目的:高速道岔铺设是客运专线轨道工程施工的重点和难点,传统施工方法难以满足高速道岔铺设的标准和要求,必须研究有砟高速道岔施工的新技术,以提高道岔的铺设质量和铺设效率.研究结论:结合甬台温客运专线铁路轨道工程高速道岔施工情况,国内首次研制了有砟高速道岔基地组装平台,开发出高速道岔平台预组装、整组运输及铺设成套技术,实现了高速道岔铺设基地工厂化、机械化、专业化施工,完全符合铁道部关于高速道岔施工技术的要求.该成套施工新技术先进合理,有效提高了高速道岔的铺设质量和铺设效率,极大地缩短了施工工期,节约了施工成本,为高速道岔铺设提供了参考.%Research purposes: Laying turnout is the key point and one of the most difficult works in construction of high- speed railway.The traditional construction methods can not meet the standards and requirements of laying the turnout of high - speed railway.So the study has to be done on the new technology of laying ballast turnout of high-speed railway to improve the quality and efficiency of laying turnout.Research conclusions: For laying the turnouts of Ningbo -Taizhou -Wenzhou Passenger Dedicated Line, the base platform for assembling the turnout of high - speed railway has been developed in China for the first time, and the complete technologies of pre - assembling the turnout of high - speed railway on the base, transporting the entire turnout unit and turnout laying have been developed to realize the factory, mechanization and specialization constructions of the turnout laying base for high -speed railway.This completely conforms to the technical requirement of the Ministry of Railways for laying the turnout of high - speed railway.This new complete construction technologies are advanced and reasonable and can be as the reference to the similar works.By using this complete technologies, the quality and efficiency of laying the turnout of high - speed railway can be enhanced effectively, the construction period can be much shortened and the construction cost can be cut.
