Pipeline structure and rapid laying method for single-layer vacuum pipeline or double-layer vacuum pipeline of pipeline structure

Abstract

The invention discloses a pipeline structure and a rapid laying method for a single-layer vacuum pipeline or a double-layer vacuum pipeline of the pipeline structure. The pipeline structure comprises an inner layer spiral pipe, an outer layer spiral pipe, a high-strength rigid filler arranged between the inner layer spiral pipe and the outer layer spiral pipe in a filled mode and a tensioning piece for combining the inner layer spiral pipe with the rigid filler as well as the outer layer spiral pipe with the rigid filler into a whole. The tensioning piece is fastened with the inner layer spiral pipe and / or the outer layer spiral pipe, and the inner diameter of the inner layer spiral pipe is larger than or equal to 3 m and is smaller than or equal to 15 m. According to the pipeline structure designed by using the structure, the pipe diameter is large, the pipeline strength is high, the cost is low, and processing is convenient; and the two pipelines in the structure are superimposed up and down, and a temporary conveying track and a permanent conveying track are arranged so that rapid erection of the single-layer vacuum pipeline or the double-layer vacuum pipeline can be conveniently realized, and the structure is stable and reliable.

Description

technical field [0001] The invention relates to the technical field of high-speed trains, in particular to a pipeline structure and a rapid laying method of a single-layer or double-layer vacuum pipeline. Background technique [0002] High-speed trains are the development direction of modern high-tech rail transportation. After the high-speed rail with wheel-rail technology reaches a speed of 400KM / h, there is no room for higher development due to the reduced friction between the wheels and rails. The way to achieve higher speed train running speed can also adopt the magnetic levitation system, which realizes the non-contact suspension and guidance between the train and the track through electromagnetic force, and then uses the electromagnetic force generated by the linear motor to pull the train to run. At present, the maglev train system can be divided into two directions, namely the constant conduction magnetic attraction (EMS) train adopted by Germany and the superconduc...

Problems solved by technology

[0004] Most of the pipe structures used in large-scale buildings in the prior art are formed by integral welding of metal plates, so there are many problems such as high structural elastic modulus, easy corrosion, and high production costs.

[0005] In addition, most of the vacuum pipes designed for high-speed trains in the prior art are also set up with metal pipes, so there are also the above defects, and there are also a series of problems such as poor sealing after erection and low erection efficiency.
