中低速磁浮道岔安装调试技术

Installation and Debugging Technology of Medium-low Speed Maglev Turnout

针对我国首条自主设计、施工的中低速磁浮交通长沙磁浮快线全线7组磁浮道岔安装技术难度大、精度要求高、结构复杂、接口关系多、首次桥上吊装等特点,开展中低速磁浮道岔安装调试技术研究。长沙磁浮快线成功运营表明,根据几何关系计算道岔基准点坐标,采用CPⅢ测量控制方法对基准点放样;基础二次浇筑混凝土工艺;道岔结构件吊件工艺;道岔单调、联调和车岔联调方法等中低速磁浮道岔安装调试方法正确,满足了磁浮道岔安全、平稳、可靠性要求,磁浮车辆通过磁浮道岔时运行平稳舒适。

According to the characteristics of 7 groups of maglev turnouts in Changsha Maglev Express,which is the first self-designed and constructed medium-low speed maglev traffic line in China,such as difficult installation technology,high precision requirements,complex structure,many interface relations,the first hoisting on the bridge,the research on the installation and debugging technology of medium-low speed maglev turnouts was carried out.The successful operation of Changsha Maglev Express shows that the installation and debugging methods of medium-low speed maglev turnouts,such as calculating the coordinates of turnout reference points according to the geometric relationship,setting out the reference points with CPⅢ measurement control method,secondary pouring concrete technology of foundation,hoisting technology of turnout structural parts,monotonous turnout,joint commissioning and vehicle turnout joint commissioning method,are correct and meet the safety,stability and reliability requirements of maglev turnouts.The maglev vehicle runs smoothly and comfortably when passing through the maglev turnout.
