un-shaped vacuum pipeline beam
The invention provides a un-shaped vacuum pipeline beam which comprises an n-shaped pipeline cover on the upper part and a u-shaped track beam on the lower part; the u-shaped track beam comprises a left side wall, a right side wall and a track bottom; sealing connecting grooves are formed in the positions, close to the edges, of the upper end faces of the left side wall and the right side wall of the u-shaped track beam; and the lower end parts of the n-shaped pipeline cover at the upper part match and are tightly buckled with the sealing connecting grooves in the upper end surfaces of the left side wall and the right side wall of the u-shaped track beam to form a hollow pipeline. The use amount of materials such as steel bars and concrete can be reduced, and the cost of the vacuum pipeline is reduced; the air tightness problem of a pure concrete beam is also solved, and meanwhile, the eddy resistance of a maglev train during high-speed operation can be effectively reduced; the problem of structural strength caused by atmospheric pressure difference is effectively solved; and heat generated by the coil of an electric appliance can be effectively conducted to the outside atmosphere.
本发明公开了一种∪∩型真空管道梁，包括上部的∩型管道盖和下部的∪型轨道梁；所述∪型轨道梁包括左侧壁、右侧壁和轨底；所述∪型轨道梁的左侧壁和右侧壁的上端面靠近边缘处设有密封连接槽；所述上部的∩型管道盖的下端部与∪型轨道梁的左侧壁和右侧壁上端面上的密封连接槽匹配紧密扣合，形成中空的管道。本发明能够减少钢筋、混凝土等材料用量，有利于降低真空管道成本；也解决了单纯混凝土梁的气密性问题，同时能够有效地降低磁浮列车高速运行时的涡流阻力；还有效地解决了大气压差导致的结构强度问题；并可以有效地将电器线圈的发热传导到外界大气中。
