Problems solved by technology

[0003] The present invention solves the existing problems of the existing road and bridge deck deicing methods: 1. Make the melted salt water penetrate into the reinforced concrete, causing severe corrosion to the structure, speeding up the damage to the building, and bringing safety problems to the building. 2. Large investment and high energy consumption; 3. This snow removal method not only causes certain damage to the road and bridge decks, but also costs a lot, the machinery is expensive, and its maintenance costs are high; the cooling of roads and bridge decks in summer only depends on sprinkling water , a waste of resources, and the problem of short maintenance time, a road and bridge cooling and ice and snow melting device using underground natural energy is provided. The specific technical solution to solve the above problems is as follows:

specific Embodiment approach 2

[0009] Specific Embodiment 2: This embodiment will be described in conjunction with FIG. 1 . In this embodiment, the input end of the compressor 1 is connected to the second output end of the evaporator 4 shell side, the output end of the compressor 1 is connected to the second input end of the condenser 2 shell side, and one end of the expansion valve 3 is connected to the evaporator 4 is connected to the second input end of the shell side, and the other end of the expansion valve 3 is connected to the second output end of the condenser 2 shell side.

[0010] Both the deep heat exchanger 6 and the shallow heat exchanger 7 are made of high-density polyethylene pipes or steel pipes. The embedding depth is 50mm-80mm from the ground (bridge) surface, which should be determined according to the load on the road (bridge) surface, the temperature of the heating fluid in the pipe and buried pipe. The underground energy-taking pipe is calculated based on the bridge (road) surface loa...

Description

technical field [0001] The invention relates to a road and bridge cooling and melting ice and snow device. Background technique [0002] At present, the ways of removing snow from the road (bridge) surface in winter are as follows: Chemical snow melting: 1. This method makes the melted salt water penetrate into the reinforced concrete, causing serious corrosion to the structure, speeding up the damage to the building, and ensuring the safety of the building. The problem has brought huge hidden dangers; 2. When melting snow, the heat required for snow melting mainly comes from the bridge deck, which causes the bridge deck to frequently expand and contract with heat and cold, causing the bridge deck concrete to peel off and damage the bridge deck; 3. Snow melting salt water will cause environmental damage. Pollution has a great impact on ecosystems such as plants and destroys people's living environment; 4. Snowmelt salt water flows into the sewer, which will also cause great ...
