uun-shaped double-line vacuum pipeline beam
The invention provides a uun-shaped double-line vacuum pipeline beam. The pipeline beam comprises an outer shell concrete track beam on the lower portion and a pipeline cover on the upper portion. The cross section of the outer shell concrete track beam is in the shape of two u-shaped parts which are arranged side by side, namely uu-shaped parts; the pipeline cover is n-shaped; the uu-shaped outer shell concrete track beam comprises a first track beam and a second track beam; the first track beam comprises a first left side wall, a first right side wall and a first track bottom; the second track beam comprises a second left side wall, a second right side wall and a second track bottom; the upper ends of the first right side wall and the second left side wall are connected through a connecting plate; sealing connecting grooves are formed in the upper ends of the first left side wall and the second right side wall; and the lower ends of the n-shaped pipeline cover match and are tightly buckled with the sealing connecting grooves of the uu-shaped track beam to form a hollow vacuum pipeline. The cost of the pipeline beam is reduced; the problems of air tightness and structural strength of the concrete beam are solved; and the eddy resistance during the operation of a maglev train is reduced.
本发明公开了一种∪∪∩型双线真空管道梁，包括下部的外包壳混凝土轨道梁和上部的管道盖；所述外包壳混凝土轨道梁截面呈并排在一起的两个∪型，即∪∪型；所述管道盖呈∩型；所述∪∪型外包壳混凝土轨道梁包括第一轨道梁和第二轨道梁；所述第一轨道梁包括第一左侧壁、第一右侧壁、第一轨底；所述第二轨道梁包括第二左侧壁、第二右侧壁、第二轨底；所述第一右侧壁和第二左侧壁的上端通过联系板相连接；所述第一左侧壁和第二右侧壁的上端设有密封连接槽；所述∩型管道盖的下端与∪∪型轨道梁的密封连接槽匹配紧密扣合成中空的真空管道。本发明降低了管道梁成本；解决了混凝土梁的气密性及其结构强度问题；降低磁浮列车运行时的涡流阻力。
