The invention relates to a communication base station with a water leakage prevention function. The communication base station comprises a body, a base, a waterproofing mechanism and a repairing mechanism, wherein the repairing mechanism comprises a guiding rod, a second moving assembly, a nozzle, a material delivery pipe, a high-pressure pump, a material storage box, two guiding rails and two first moving assemblies, and the repairing mechanism further comprises a driving assembly, a rotary shaft, a first gear, two first transmission rods, two reinforcing sleeve tubes and two transmission assemblies. According to the communication base station with the water leakage prevention function, the nozzle can be driven to move on the station through the repairing mechanism, asphalt is sprayed onthe station through the nozzle, so that the repairing of cracks on the top of the communication base station is achieved, the possibility of water leakage occurrence of the communication base stationis reduced and the practicability of the communication base station is improved, through the repairing mechanism, the communication base station can be driven to lift up and lower down, so that the possibility that accumulated water flows into the communication base station is reduced, and the practicability of the communication base station is further improved.
