Automatic bridge deck snow melting and deicing system and method based on terrestrial heat

Abstract

The invention discloses an automatic bridge deck snow melting and deicing system and method based on terrestrial heat, and the system comprises a monitoring module, a snow melting and deicing module,and a control module. The monitoring module comprises a weather monitor, and a temperature and humidity sensor and an icing detector which are arranged on the bridge deck; the snow melting and deicingmodule comprises a heating pipeline buried under the bridge deck and a geothermal system connected with the heating pipeline; the control module comprises a field control system and a remote controlsystem; and the remote control system is used for judging whether the bridge floor is frozen or not according to the temperature and humidity of the bridge floor and then starting the snow melting anddeicing module in advance according to a result, controlling the heat exchange amount of the snow melting and deicing module and sending bridge floor icing early warning. According to the invention,the bridge deck can be monitored, the icing time and thickness of the bridge can be pre-judged, the ice melting system can be automatically started and stopped, the heating time period, area and powercan be intelligently controlled, and active, intelligent and accurate ice melting can be realized.

Description

technical field [0001] The invention belongs to the technical field of bridges, and relates to a bridge snow-melting and ice-melting technology, in particular to a geothermal-based automatic snow-melting and ice-melting system and method for bridge decks. Background technique [0002] 56% of my country's land, 70% of the bridges are in the ice area. Icing causes the braking distance of road vehicles to be 6-7 times that of normal roads, which is very likely to cause traffic accidents. Extreme weather will blur the vision of drivers, reduce the efficiency of road transportation, cause damage to traffic facilities and vehicles, and seriously lead to road closures. The existing methods of melting snow and ice mostly use chemical and mechanical ice melting, which requires a lot of labor and construction machinery, and will also cause damage to the surrounding environment, and some technologies are difficult to implement, and cannot remove snow and melt ice according to the actu...
