Corrosion prevention method for steel bars of concrete foundation of power transmission tower in salinized soil environment
The invention relates to a steel bar corrosion prevention method and structure for a power transmission tower concrete foundation in a salinized soil environment. An induction coil is placed on a high-voltage power transmission line, the two ends of the coil are connected with a rectifier bridge circuit, the cathode output end of the rectifier bridge circuit is connected to a corresponding power transmission tower foot through a copper wire, and the anode output end is connected with an auxiliary anode; the auxiliary anodes are placed around the tower foot of the power transmission tower, and the tower foot of the power transmission tower and the auxiliary anodes form a closed loop through soil. Self-energy taking is achieved based on the principle of electromagnetic induction, the detection coil generates induced electromotive force in a changing magnetic field around a high-voltage transmission line to serve as a power source for impressed current cathode protection, protection voltage is adjusted by designing reasonable coil size, distance and the like, and therefore control over tower foot steel bar protection current is controlled; the consumption rate of the auxiliary anode is reduced, and long-term protection of corrosion of the steel bars of the power transmission tower concrete foundation is achieved. The method has good economic benefits and environmental benefits.
