Problems solved by technology

[0013] On the other hand, the span between the piers and abutments of the submarine vacuum pipeline is relatively large, and there will be flexion and sag in the middle of the suspended pipeline. When the vacuum pipeline vehicle passes, the sag will increase, which will affect the stability and safety of driving.

Abstract

The invention discloses a pre-tensioned submarine vacuum pipeline structure and a stretching method thereof, which can improve the rigidity of the submarine vacuum pipeline, minimize the drooping of the middle part of the suspended pipeline, and ensure smooth and safe driving. The structure includes a submarine vacuum pipeline and multiple piers , the submarine vacuum pipeline is fixedly supported on the top of the abutment, and the abutment has elastic strength. The submarine vacuum pipeline includes a plurality of vacuum pipeline sections arranged in sequence. The vacuum pipeline sections have tensile strength. The opposite ends of the two adjacent vacuum pipeline sections Flanges are provided, and there is a gap between the flanges of two adjacent vacuum pipeline sections, and the flanges of the two adjacent vacuum pipeline sections are connected by a tensioning mechanism; the stretching method includes multiple vacuum After partial grouping of the pipeline sections, the sorting stretching method is used for stretching, and the step-by-step stretching method is used to make each vacuum pipeline section stretch step by step, and the gap between the flanges of two adjacent vacuum pipeline sections is divided. step stretch closed.

Description

Technical field [0001] The present invention belongs to the field of submarine vacuum pipeline transportation and marine engineering technology, specifically relates to a pre-tension seabed vacuum pipeline structure and a tensile method thereof. Background [0002] High-speed railways and maglev trains are restricted by air resistance, aerodynamic noise, and pneumatic vibration, and it is difficult to further increase their speed. In addition to being affected by air resistance, aircraft and cars have high energy consumption and carbon emissions, and their future development will be limited. Vacuum pipeline high-speed maglev traffic to overcome the above shortcomings, can achieve ultra-high speed, and low energy consumption, small environmental impact, is expected to create a new situation in human transportation. [0003] Vacuum pipeline traffic is composed of pipelines, vehicles, power supply, communication, drive and control, vacuum pump group, monitoring system and other part...
