Disposable coverage structure for railway track freezing disaster treatment

Abstract

The invention discloses a disposable coverage structure for railway track freezing disaster treatment. The invention belongs to the field of railway tracks, and discloses the disposable coverage structure for railway track freezing disaster treatment. When freezing weather occurs, external rain and snow melted water can permeate into an anti-freezing warm layer and then enter a self-heating warm bag, and heating particles can emit heat when meeting water, so the rail can be effectively protected from being influenced by freezing weather; the service life of the rail is prolonged; the self-heating warm bag emits heat, so that the temperature near the rail can be increased, thus accelerating melting of rain and snow, meanwhile, the freezing phenomenon near the rail is effectively avoided; the influence of freezing weather on rail transit is effectively reduced; meanwhile, through a base layer, when the temperature rises after the freezing weather, the distance between gas molecules in the base layer is increased, the position near the base layer is loosened, and the coverage is convenient to detach; the coverage is disposable only in freezing weather, and the situation that the railsare damaged due to the fact that the temperature of the rails rises in a high-temperature environment is effectively avoided.

Description

technical field [0001] The invention relates to the field of railway tracks, and more specifically relates to a disposable layer structure for railway track freezing disaster treatment. Background technique [0002] There is snow and ice on the rails, especially at the turnouts entering and leaving the station, which affects the safe running of the train. In the cold wave and low temperature weather, ordinary EMUs do not have special cold-proof facilities. If the temperature is lower than a certain range, mechanical problems may occur. On the other hand, rain and snow Freezing poses a safety hazard to the catenary and the track. During the outbreak of the cold wave, low temperature and heavy snow weather is still relatively rare in the southern region. Affected by this, high-speed trains such as the Beijing-Shanghai Railway have become "slow trains" with a speed of 9 kilometers per hour, and high-speed trains such as Beijing-Shanghai and Shanghai-Kunming have experienced del...

Problems solved by technology

[0006] In view of the problems existing in the prior art, the object of the present invention is to provide a kind of disposable layer structure for the treatment of railway track freezing disasters, which can pass through the antifreeze warm layer arranged on the surface of the rails. When freezing weather occurs, the external The water melted by rain and snow can penetrate into the self-heating heating bag, and the heat-generating particles in the self-heating heating bag will generate heat when they meet water. On the one hand, it can effectively protect the rails from being affected by freezing weather, thereby prolonging the service life of the rails. On the one hand, the heat generated by the self-heating warmer can increase the temperature near the rails, thereby accelerating the melting of rain and snow. In conjunction with the existing freezing treatment, it can effectively avoid the occurrence of freezing near the rails and effectively reduce the impact of freezing weather on rail traffic. Through the setting of the base layer, after the freezing weather, the temperature rises and the distance between the gas molecules in the base layer increases, which can loosen the vicinity of the base layer and facilitate the removal of this layer, making this layer only for one-time use in freezing weather , to effectively avoid the damage to the rails caused by the heating of the rails in a high-temperature environment due to the structure of this layer
