Fragile remains with complex overlapping are often encountered in archaeological excavations and are difficult to extract. This paper takes, as an example, the left wheel remains of the No.5 chariot from CMK2 at Gujun site in Xingtang County, Hebei Province, for introducing a method for the extraction of large fragile remains using the technology of temporary consolidation with menthol and rigid support. Through careful excavation and pre-detection, wheel body reinforcement, temporary consolidation with menthol, rigid bracing addition, overall extraction, back cleaning and reinforcement, front cleaning conservation and other technical processes, the left wheel remains were successfully extracted and conserved. Among these processes, excavation technology, rigid support technology and menthol as a temporary consolidant play key roles. This study provides a technical reference for the overall extraction and conservation of such large-plane fragile remains.
