However, most of the existing shield tunneling machines are propelled by circulating water systems or air cooling systems. The circulating water system utilizes circulating water to take away local redundant heat of a hydraulic part of the shield machine, but the method still cannot achieve a good cooling effect, so that accidents caused by overhigh temperature often occur, the circulating water system is adopted for cooling, the water outlet temperature of circulating water is about 40 ℃ generally, and the water inlet temperature is about 25 ℃, so that the shield machine can realize good operation, but if summer weather is hot (the summer temperature is about 30 ℃), the water inlet temperature can rise to about 30 ℃, so that the hydraulic part of the shield machine is heated quickly and cooled slowly, the expected cooling effect cannot be achieved, the phenomenon that the shield machine is frequently stopped and cooled is easily generated, the construction progress is influenced, and the shield machine is mistakenly worked and mistimed, so that double losses in time and economy are caused.
