The invention discloses an automatic watering maintenance system of concrete pole foundation. The automatic watering maintenance system of the concrete pole foundation is characterized in that a global positioner is arranged at the upper end of a water storage pressure tank. A positioning tooth base is arranged at the lower end of the water storage pressure tank. Telescopic positioning rods are transversely arranged on a tank body of the water storage pressure tank arranged on the base in a spaced mode. One end of each positioning rod is hinged to a positioning convex lug arranged on the tank body. The other end of each positioning rod is connected with a positioning clamping jaw through a cardan joint. A water outlet provided with a valve of the water storage pressure tank is connected with an automatic timed watering sprinkler arranged on a support through a duct. The automatic watering maintenance system of the concrete pole foundation has the beneficial effects that 1, the automatic watering maintenance system is convenient to assemble, disassemble, carry and use, and capable of achieving the effect that the system is assembled when is needed to be used and is disassembled when is not used; 2, the system is provided with a global positioning system, so that the equipment control and management are convenient, and the anti-theft property is high; 3, the adaptation for dealing with the severe environment is high, the system can be used in various occasions, and the cost performance is high; and 4, the automation of the concrete maintenance is achieved; the labor is saved, and the cost is low and reduced.
