With the development of national economy of China, the requirements of people on the quality of travel are higher and higher, and a higher-speed and more comfortable traffic mode is more and more popular. The method is limited by the influence of factors such as wheel-rail relationship, operation environment and the like, and the running speed of the high-speed railway train with the design speed of 350km/h at present is difficult to be greatly improved. Therefore, maglev rail transit having a higher speed than a high-speed train of a wheel track becomes a development focus in the future. The magnetic suspension traffic system is a track traffic system adopting non-contact electromagnetic suspension, guidance and driving, does not have wheels of the traditional wheel-rail vehicle, generates strong electromagnetic attraction or repulsion through an active suspension control system to enable the vehicle to stably suspend, and provides traction force by using a linear induction motor. At present, the suspension gap of a magnetic suspension train is only about 10mm generally, and the magnetic suspension transportation system has higher requirement on the track line shape because of high speed.

After the filling and height-adjusting mode is used for height adjustment, the height adjustment can be generally performed only once due to pipeline blockage.
