Face is destroyed, and lacquer painting is easy to aging, so that corrosion resistance is poor；For the anchorage style using concrete package due to anchor head coagulation
Strong bond can not be formed between soil and slope surface, is easily formed as plane of weakness, corruption easily occurs for contact surface position under dry wet alternating environment
Erosion, so that anchor ingot plate and anchor pole be caused to corrode；Second, anchor head exposed parts are smaller and quantity is more, according to general concrete
Protection, since the smaller concrete formation of anchor head is difficult, difficulty of construction is big, situations such as shrinkage cracking, voids and pits easily occurs, from
And substantially reduce it and protect effectiveness, cause anchor pole to corrode.Therefore corrosion resistant anchor head has wide application market.
