At present, according to related researches at home and abroad, it can be known that the high geothermal conditions have a plurality of adverse effects on the construction of underground engineering. The high heat not only deteriorates the tunnel construction environment, reduces the winter-raising productivity of the operation, but also seriously threatens the health and the safety of constructors; meanwhile, the temperature stress of the accessory generated by the high terrestrial heat can also cause the cracking of the lining, so that the safety and the durability of the lining structure are not good; in addition, the high-temperature and high-humidity environment of the tunnel cavern may cause increased failure of construction machinery, reduced work efficiency, and the like. Therefore, how to reduce the temperature in the tunnel chamber of the construction tunnel in the high geothermal area section and control the temperature under an environment condition suitable for personnel and mechanical construction operation has great significance for ensuring the safety, construction quality and construction progress of tunnel construction.
At present, the rapid cooling method comprises the steps of cooling ice blocks in holes, cooling by spraying in the holes, cooling fans in the holes, air conditioners in the holes and the like besides the conventional enhanced ventilation.

The utility model discloses a utility model patent of application number CN200720073392.X relates to a temperature control structure in tunnel, is particularly useful for the longer, the alternating current gauge height of tunnel ventilation district section, the higher engineering of temperature in the tunnel, and this structure includes the tunnel inner wall, its characterized in that be provided with the spraying shower nozzle on the inner wall, the spraying particle diameter of shower nozzle is not more than 50 mu m, and its advantage is, effectively reduces the interior air dry bulb temperature of tunnel, improves the inside air quality in long tunnel greatly, guarantees that the vehicle normally passes.
The utility model patent application No. CN01279571.2 relates to a special air conditioning unit in tunnel, and it is mainly used in high altitude, high cold and high temperature area to and in the construction tunnel of the harsh natural environment of high humidity, extra dry. The unit is arranged in an air-conditioning heat preservation box body, a heating surface air cooler and a double-speed tunnel fan are arranged to form the air-conditioning unit, and a temperature control device is additionally arranged. The air conditioning unit can heat or cool ambient air, and in addition, after the tunnel is blasted, the unit can run at a high speed, so that smoke and dust in the tunnel can be rapidly removed.

For the long and large tunnel in the high geothermal region, the ice blocks are arranged to only temporarily provide a local cooling effect, workers need to have a rest and rotate for many times in the operation, the team cost is increased, and meanwhile, the ice making cost is high and the energy consumption is high. Although air coolers, air conditioners and the like have good refrigeration effects, the energy consumption is high, and under the condition that the dust air environment in the tunnel is not good, the air conditioners are difficult to maintain and maintain, need to be cleaned frequently and are not suitable for large-scale refrigeration. The spraying cooling is applied to operating tunnels more, the cooling effect can reach about 4 degrees, but the application of the spraying cooling in the tunnel is not common, and the cooling effect is mainly limited by the ventilation air speed in the tunnel and the temperature of cold water spraying. For the tunnel with the terrestrial heat of over 50 degrees in the tunnel, such as some long and large tunnels in Yunnan and Tibet areas, the high temperature in the local tunnel can reach 70 degrees, and the terrestrial heat problem becomes a main factor for restricting the tunnel construction.
It can be seen that for high-grade geothermal tunnels, the cooling capacity of the methods is limited, mainly the cooling by air exchange is limited by the small specific heat capacity of air, and the geothermal heat can be transferred into the tunnel through rock walls and concrete behind the tunnel face.
