Abstract

The invention discloses a railway frost-resistant base suitable for alpine regions and a construction method thereof, belonging to the technical field of railways, comprising an inner frame, a concrete layer is laid on the outer periphery of the inner frame, and a heating sheet A and a heating element are laid on the outer periphery of the concrete layer. Sheet B, heating sheet A and heating sheet B are all provided with insulation boards on the periphery, heat insulation boards are laid on the periphery of the insulation boards, and antifreeze paint layers are arranged on the insulation boards. The railway frost-resistant base and its construction method suitable for high-cold regions of the present invention heat the base through the heating sheet A and the heating sheet B, and the heat preservation and heat insulation of the base can be carried out through the heat preservation board and the heat insulation board. Avoid rapid heat dissipation and improve the antifreeze performance of the base. At the same time, an antifreeze coating layer is set on the heat insulation board. The surface has low surface tension, high water and ice repellency, and reduces the adhesion of water and ice, making it extremely Easy to fall off, so as to achieve the purpose of anti-icing and anti-freezing.

Description

technical field

[0001] The invention relates to the technical field of railways, in particular to a railway frost-resistant base suitable for high cold areas and a construction method thereof. Background technique

[0002] Railway transportation is a land transportation method in which locomotives pull train vehicles on two parallel rails. The traditional way is to travel on steel wheels, but railway transportation in a broad sense includes maglev trains, cable cars, cableways and other non-steel wheel travel methods, or rail transportation. The rails provide an extremely smooth and hard medium on which the train wheels roll with minimal friction, making it more comfortable for people on it, and it saves energy. If properly configured, rail transport can save 50 to 70 percent of energy compared to road transport for the same weight. Moreover, the rails can evenly disperse the weight of the train, so that the load-carrying capacity of the train is greatly improved. [0003...
