Novel nanometer thermal probe high-speed railway roadbed for frost heave prevention of roadbed in seasonal freeze soil area

Abstract

The invention discloses a novel nanometer thermal probe high-speed railway roadbed for frost heave prevention of a roadbed in a seasonal freeze soil area. A novel measure is provided for frost heave prevention design and frost heave government of the high-speed railway roadbed in the seasonal freeze soil area. 'Active preventing and curing' is taken as a core concept in a novel nanometer thermal probe technology, solar energy is used for driving, heat is inputted without dynamic heating, the temperature of a soil body is increased, the frozen depth of a seasonal active layer of the roadbed isdecreased, and the purpose that longitudinal irregularity and transverse deformation difference of the roadbed caused by frost heave are eliminated or reduced is achieved. Furthermore, on the aspect of frost heave preventing and curing of existing railroads, most of engineering measures are faced with limiting of high constriction difficulty and short business line skylight time in the applicationprocess, and the thermal probe has the advantages that construction is easy, interference on the roadbed structure and business lines is less, and the influence on the ecological environment is small. According to the novel nanometer thermal probe high-speed railway roadbed, the nanometer thermal probe technology is used for eliminating or reducing generation and development of frost heave of thehigh-speed railway roadbed, and the stability of the roadbed and the safety of train operation are guaranteed in the low temperature season.

AI Technical Summary

Benefits of technology

This patented technology allows for better monitoring and controlling when there's snow or ice that may occur during travel at different temperatures over time by utilizing an improved way of regulating the amount of power supplied from sunlight into the train track system. It also includes features like easy installation without damaging existing equipment, efficient operation with minimal maintenance costs, and effective cooling systems. Overall, this innovation improves efficiency and performance while reducing damage caused by excessive welded joints between components.

Problems solved by technology

This patented technology addresses issues related to maintaining safe roads during winter months when snow forms along long sections of rails due to freezing conditions or other factors like rainwater damage. However, current designs may still allow ice formation underground without affecting their functioning well. Additionally, some conventional solutions such as adding sand layers between tires and create watertight joints result in increased pressure applied across the interface, leading to instability over longer periods.
