Inhaul cable embedded pipe dehumidification system

The invention relates to the technical field of bridge engineering, in particular to an inhaul cable embedded pipe dehumidification system which comprises an inhaul cable embedded pipe, an inhaul cable, dehumidification equipment, a ventilation pipeline and a multiple rainproof sealing cover. The dehumidification equipment is used for converting wet air into dry air, so that the relative humidity is kept below a value required by corrosion prevention; the ventilation pipeline is used for mutually connecting the inhaul cable embedded pipes, conveying moist air in the inhaul cable embedded pipes to the dehumidification equipment and conveying treated dry air back into the inhaul cable embedded pipes; the multi-rain-proof sealing cover is arranged between the inhaul cable embedded pipe and the inhaul cable and used for preventing rainwater from entering the inhaul cable embedded pipe, and the sealing effect is achieved. The relative humidity of air in the inhaul cable embedded pipe is maintained below the limit
