What techniques were used to excavate the Terracotta Warriors?

Archaeologists used brushes and other tools to remove the soil from the remains of the terracotta warriors. Almost every unearthed terracotta Warrior consists of thousands of fragments. In addition to professional archaeological tools, there is also a common hospital bed, as well as human traction equipment for repairing. The Terracotta Warriors have not been fully excavated since the technology is not perfect.
