[0002] With the expansion of the national urbanization scale, the urban population has surged, the demand for traffic flow has continued to increase, and urban traffic congestion has occurred frequently. Expanding underground space and improving transportation capacity have become new themes for urban development. Underground facilities such as urban expressways, rail transit projects, and underground ring road projects have become the new mainstream, and many new underground projects are increasingly moving closer to the core areas and prosperous areas of the city. Taking a certain underground tunnel project as an example, the project is located in the core area, and the surrounding area is surrounded by many complex complexes such as commercial areas and historical areas. The surrounding buildings (structures) are densely populated, the population density is large, the traffic is busy, and there are many national and municipal cultural relics. Tunnel excavation construction cannot be carried out by conventional drilling and blasting methods. Combined with the engineering geology of sandstone formations (intact rock and high strength), only high-power modified breaker hammers can be used for tunnel excavation construction. The single-cycle excavation time of the tunnel reaches 20-28 hours. The long-term crushing construction of high-power equipment results in high construction environment temperature in the tunnel.

By placing ice cubes into the ice trough, the temperature in the box body 6 forms a lower temperature environment under the action of the ice cubes, and the axial flow fan 7 is combined to blow out cold air, thereby improving the cooling effect. In addition, the design of the track body 5 and the track wheel 4 makes it easy to move the device, thereby cooling the environment in different areas.
