Anchor head sealing method, anchor head sealing replacement method and anchor head sealing cover assembly

The invention discloses an anchor head sealing method, an anchor head sealing replacement method and an anchor head sealing cover assembly, a sealing piece, a pressing plate and a sealing cover which are split are adopted, and the pressing plate presses the sealing piece through cooperation of an inner step and an outer step on the sealing cover. When sealing replacement of the anchor head is carried out, switching is carried out between the top of the pressing sealing cover and the step through external force, an old sealing piece can be conveniently detached and replaced with a new sealing piece, and it is ensured that anti-corrosion grease does not overflow in the sealing piece replacement process. According to the invention, the sealing element can be replaced only by dismounting a part of components with smaller weight and volume, the leakage problem of anti-corrosion grease is not easily caused when the sealing element is replaced, and the replacement operation difficulty is low. 本发明公开了一种锚头的密封方法和密封更换方法以
