Bridge deck anti-icing device

Abstract

A bridge deck anti-icing device is composed of a transverse heat conduction pipe, a bridge deck main body with a groove, a bridge deck surface layer, a temperature control box, a heating source and a power line. The transverse heat conduction pipe is embedded into the groove of the bridge deck main body; the diameter of the groove is adapted to the transverse heat conduction pipe and the bridge deck surface layer covers the transverse heat conduction pipe. The transverse heat conduction pipe transversely passes through a whole lane and the other end of the transverse heat conduction pipe is connected with the heating source; the temperature control box is engaged with the heating source by the power line. When the temperature of a bridge deck is lower than 2 DEG C, the heating source is automatically opened by the temperature control box and a heat source is transmitted to the surface of the bridge deck heat conduction pipe, so that the bridge deck surface layer is heated and the bridge deck is prevented from being iced. The temperature of the bridge deck surface layer keeps more than 0 DEG C by the heat conduction pipe through the heating source; with the adoption of the device, the icing problem of the bridge deck can be solved, the driving safety is improved and the accidents are reduced.

Description

technical background [0001] The invention relates to the field of bridge construction, in particular to a device for preventing bridge deck from freezing in winter. Background technique [0002] Due to the volley around the bridge deck, the heat dissipation conditions are good, the thermal insulation conditions are poor, and there is no compensation for ground temperature, so it is easy to freeze. Due to the icing of the bridge deck and the loss of control of the brakes and slipping vehicles, accidents such as multi-vehicle overturning and rear-end collisions occurred frequently, resulting in large-scale paralysis of highways, national highways and other major traffic roads. At present, the only countermeasures are salt spraying, mechanical and manual deicing, which greatly wastes national resources such as manpower and material resources. In this context, using the present invention can completely solve the above problems, and is suitable for various bridge decks, especial...

AI Technical Summary

Problems solved by technology

[0002] Because the bridge deck is surrounded by air, the heat dissipation conditions are good, the heat preservation conditions are poor, and there is no ground temperature compensation, so it is easy to freeze

Due to the ice on the bridge deck, the brakes slipped and the vehicles lost control, resulting in frequent accidents such as multiple vehicles overturning and rear-end collisions, causing large-scale paralysis of highways, national highways and other major traffic arteries

At present, the only countermeasures are salt spreading, mechanical and manual deicing, which greatly wastes national resources such as manpower and material resources.
