New Technology of Laying Ballast Turnout of High-speed Railway

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.
