6. A processing method for a bridge sling configured for electrochemical detection of steel wire corrosion, including the following steps:
step a, wrapping a steel wire bundle with a wrapping tape to expose the two ends of the steel wire bundle, and welding the exposed ends of the steel wire bundle with a test wire;
step b: spraying a shielding coating to the outside of the wrapping tape, and welding another test wire on the shielding coating;
step c: forming a circle of inner protective layer at the exterior of the shielding coating by injection molding, and sleeving the inner protective layer with a steel pipe;
step d: sequentially sleeving the tail ends of the steel pipe with sealing cylinders and anchor cup bodies for sealing heads of the sealing cylinders, and for screwing tails of the sealing cylinders with the anchor cup bodies, and electrically connecting two test wires with positive and negative electrodes of a voltmeter on the sealing cylinder respectively; and
step e: dispersedly fixing the exposed portions of the steel wire bundle in the anchor cup bodies.
