Before concrete pouring, check the coating of epoxy-coated steel bars, especially at the shearing end. If there is any damage, it should be repaired in time. After the repair material is cured, the concrete can be poured. When pouring concrete, an attached vibrator should be used to vibrate and compact. When a plug-in vibrator is used, plastic or rubber should be used to cover the vibrator to prevent damage to the epoxy coating during concrete vibrating.
