Embodiment 1

[0022] Figure 1-2The beam structure of the vacuum magnetic levitation pipe of the present invention is shown, which comprises: u-shaped bottom beam 1, which has a first beam end 11 and a second beam end 12, in the present embodiment, the U-shaped bottom beam 1 is a prestressed concrete structure in its entirety; And the first end portion 21 detachable connection, the second connection plate 4 is embedded within the second beam end 12, and the second end portion 22 detachable connection.

[0023] Specifically, the first connection plate 3 end is embedded within the first girder end 11, the other end is connected to the first end 21 by means of a first high-strength bolt 5 and the first end 21 removable; and / or, similarly, the second connection plate 4 is embedded at one end within the second beam end 12, the other end of the second end portion 22 through the second high-strength bolt 6 and the second end portion 22 detachable connection. Preferably, the first high-strength bolt ...

Abstract

The invention discloses a beam structure of a vacuum magnetic levitation pipeline and a vacuum magnetic levitation pipeline, comprising: a U-shaped bottom beam, which has a first beam end and a second beam end; an arc-shaped plate, which has a first end and a second beam end. two ends; and a first connecting plate and a second connecting plate, the first connecting plate is pre-embedded in the first beam end and is detachably connected to the first end, the second connecting plate is pre-buried Buried in the second beam end and detachably connected to the second end. The structure is simple and the construction is convenient. The U-shaped bottom beam that has been erected can become the channel for the subsequent beam transportation and erection, which can avoid the separate installation of pipelines on the load-bearing beam under the premise of ensuring a closed environment, which can effectively reduce the structure height and save manufacturing costs.

Description

Technical field [0001] The present invention relates to the field of vacuum magnetic levitation, in particular to a kind of vacuum magnetic levitation pipe beam structure and vacuum magnetic levitation pipeline. Background [0002] Ultra-high-speed maglev traffic generally refers to a new type of maglev system with a speed of more than 500km / h, which is mainly suitable for transportation scenarios with long transportation distance, large station spacing, multiple direct passenger flows, and wheel-rail high-speed rail is difficult to meet the requirements of time targets, mainly for passenger transportation between international and important urban agglomerations. The maglev traffic is laid in a closed vacuum pipe, which can effectively reduce the air resistance and noise of the train during ultra-high-speed operation, that is, the ultra-high-speed magnetic levitation technology of low-vacuum pipeline. [0003] At present, the ultra-high-speed magnetic levitation technology of low...
