Description

technical field [0001] The invention belongs to the waterproof field of a 500KV switch station, and in particular relates to a waterproof process for a 500KV switch station. Background technique [0002] The 500KV switch station refers to the switch station with 500KV high-voltage power, which can selectively connect or cut off the power system (grid) and its users' electrical equipment through the switchgear. Since the switch station has high-voltage power, so The switch station requires no water leakage to avoid leakage accidents as much as possible. Waterproof treatment is required during the construction of the switch station. Once leakage occurs, it needs to be repaired in time. The waterproof treatment generally deals with the floor of the basement of the switchyard, the side walls of the basement of the switchyard, the roof of the switchyard and the gutter outside the roof, mainly to prevent underground water seepage and roof rainwater leakage. The existing waterproo...
