Description

Energy storage deicing system for roads and bridges

Technical Field

The utility model relates to the field of traffic and energy fusion, in particular to an energy storage deicing system for roads and bridges.

Background

In winter, the bridge floor and road snow ice easily cause frequent traffic accidents, cause huge economic loss and casualties, and need to clear ice and snow effectively in time in order to maintain normal traffic order. The conventional methods are mainly divided into a passive snow melting and deicing technology and an active snow melting and deicing technology, wherein the passive snow melting and deicing technology mainly comprises a manual cleaning method, a mechanical cleaning method and a chemical snow melting method, and the methods are widely applied to road snow melting and deicing engineering in China, but have the problems of road (bridge) surface damage, insufficient low carbon, environmental protection, overhigh cost, limited use condition and the like. The technology for preventing road surface from icing based on the geothermal pipe method has the advantages of low carbon, green, safety, economy and the like. Geothermal pipe methods extract thermal energy from the ground rock-soil body or water body to realize road surface anti-icing, but there are some problems and challenges:

1. The initial investment is high: compared with the traditional deicing method, the buried heat exchange tube has higher installation cost. A great deal of underground works are required, including excavation, installation of pipes, and restoration of pavement.

2. Efficiency problem: in certain climatic conditions, the deicing effect of the buried heat exchange tubes may be less than desired. For example, in continuous low temperature and snowy weather, the temperature of the subsurface may not be sufficient to quickly melt snow.

3. Energy consumption: if the buried heat exchange pipe system requires additional energy to increase efficiency, the energy consumption and carbon emissions of such techniques may increase.

By integrating the geothermal pipe into the pile foundation system of the bridge, the additional excavation and land use cost required by installing the traditional ground source heat pump system can be saved, and the aim of remarkably reducing the initial investment is achieved. But this approach is still insufficient to solve efficiency and energy consumption problems. In particular, when additional non-green electrical energy is used to heat the pavement, carbon emissions and operating costs are further increased, which is in turn counter-productive to the low-carbon, green.

Thus, there is a lack of an energy efficient, environmentally friendly and economical deicing system in the art.
