Putting Anchor Bolts in zhengyu
After the zhengyu has been fixed, there are other types of bolts that may be used: epoxy bolts and mechanical bolts. Epoxy bolts are the most powerful type of bolts, but they are somewhat difficult to install, since it has to be put into the very exact position, the hole has to be ridiculously clean, and the set time has to be monitored vigilantly. If an individual does not use an epoxy bolt with caution, disaster may arise.
