Description

一种管道结构及其单层或双层真空管道的快速铺设方法 技术领域
本发明涉及高速列车技术领域，尤其涉及一种管道结构及其单层或双层真空管道的快速铺设方法。
背景技术
高速列车是一种现代高科技轨道交通发展的方向，轮轨技术的高铁做到时速400KM/h以后，由于轮轨之间的摩擦力减小就已经没有更高的发展空间了。实现更高速列车运行速度的方式还能采用磁悬浮系统，它是通过电磁力实现列车与轨道之间的无接触的悬浮和导向，再利用直线电机产生的电磁力牵引列车运行。目前磁悬浮列车系统，可以分为两个方向，分别是德国所采用的常导磁吸式(EMS)和日本所采用的超导磁斥式(EDS)列车。目前最高的车速是日本超导磁斥式(EDS)列车，达到了600KM/h，而且这一速度还没有真正的商业化运营。
速度作为人类一直追求的目标，从来只有更高，没有最高。研发新型的更为先进的交通运输工具，要想速度再有新的提升，在空气中采用以上两种磁悬浮技术已不能满足要求了。由于基于在大气当中开发的磁悬浮系统在高速状态下空气阻力所消耗的能源所占的比重越来越高，开发在真空管道中运行的磁悬浮列车系统就成为了热门学科。
现有技术下用于大型建筑的管道结构，大多采用金属板材一体焊接成型，因此存在结构弹性模量较高、易腐蚀，生产成本高等诸多问题。
此外，现有技术下针对高速列车设计的真空管道，大多也是采用金属管材设置，因此同样也会存在上述缺陷，且同时存在架设后密封性差，架设效率低等一系列问题。

3).将通过临时输送轨道依次输送来的管道单元，通过间隔设置于真空管 道支架上方的架桥机吊起，并通过设置在架桥机顶部的翻转装置将管道单元的凸台底面翻转至底面朝上设置，之后与对应的真空管道支架相配合，然后再将卸载后的输送车通过架桥机变换至永久输送轨道，以此使得输送车沿永久输送轨道返回，最后通过外部吊装设备将输送车再次变换至临时输送轨道的起点，待重新装载管道单元后继续向前行驶，依次循环，完成单层真空管道的铺设；
4).若需要进行双层真空管道的铺设时，可首先将位于上述所述单层真空管道尾部的一段临时输送轨道拆除，之后，再将通过上述步骤输送来的管道单元的下底面与输送轨道拆除后的一段凸台平面紧密配合，以此循环，完成双层真空管道的铺设。
