The invention relates to a novel anchorage device anti-corrosion structure. The novel anchorage device anti-corrosion structure comprises an anchorage plate (6), a clamping piece (7) and anti-corrosion grease (5), wherein a plurality of through holes are arranged inside the anchorage plate (6), a straight hole is arranged at the rear section of the through hole, the front section of the through hole adopts a tapered hole, after the clamping piece (7) clips a steel stranded wire (1), the clamping piece (7) is wedged into the tapered hole of the anchorage plate (6), the front end of the clamping piece (7) is exposed, and the novel anchorage device anti-corrosion structure is characterized in that an oil storage tank (4) is arranged on the end surface of the rear end of the anchorage plate (6) in a concave way, an oil filling orifice (3) is arranged in the direction toward the oil storage tank (4) from the outer edge of the anchorage plate (6) on the anchorage plate (6), the oil filling orifice (3) is communicated with the oil storage tank (4), a sealing device (2) is fixed outside the oil storage tank (4) at the rear end of the anchorage plate (6), and the anti-corrosion grease (5) is filled into the oil storage tank (4) at the rear end of the anchorage plate (6) and at the exposed clamping piece at the front end of the anchorage plate (6). The structure of the invention is simple, the anti-corrosion effect is good, and the use is convenient. The device can be extensively used in the group anchors of the steel stranded wire clamping piece of the projects of cable-stayed bridges, cables outside the concrete body, beam tying cables, and rock anchorage.
