According to previous monitoring data, the high humidity environment of certain is 30%RH~40%RH when well ventilated. After the project is plugged, the temperature is generally about 18°C, and the humidity rises quickly to about 80%RH within 2 days and gradually increases to 90%RH in next 7 to 10 days, then remaining unchanged. In order to reduce the environmental humidity after backfilling and plugging the tunnel, and control the ambient humidity below 45%RH. This paper describes a humidity control system which could achieve the isolation of the built-in dehumidification system with outside and the dehumidification with a cycle of dry and wet air in the cavern through the remote controlling. The system could accurately measure the volume of condensate water that collected automatically, and discharged the water into the multiple isolation protection deeper hole. The system accumulated dehumidified water is about 3236 kg in 24 days, and the humidity of the cavern can be effectively controlled at around 30%RH.
