The invention provides a cable trench and a cable trench drainage
system, and belongs to the technical field of
electric power facilities. The cable trench comprises a cable trench body, a drainage channel and a water collecting well, the cable trench body comprises a cable trench, a plurality of cable supports and a cable trench cover plate, the cable supports are arranged on the side wall of the cable trench, the cable trench cover plate is arranged on the upper portion of the cable trench, the drainage channel comprises a water inlet section, a bent
pipe section and a water outlet section, one end of the water inlet section is communicated with the bottom of the cable trench, the other end of the water inlet section is communicated with one end of the bent
pipe section, the other end of the bent
pipe section is communicated with one end of the water outlet section, the other end of the water outlet section is communicated with the side wall of the water collecting well, and an anti-
backflow device is arranged at the position where the side wall of the water collecting well is communicated with the water outlet section. The cable trench is good in sealing performance, cables are arranged in a layered and branched mode and can be arranged in order to facilitate laying and overhauling, meanwhile, the anti-
backflow drainage
system is arranged, accumulated water in the cable trench is reduced, and the cables are prevented from being damped and damaged.
