河北行唐故郡遗址出土脆弱质车轮提取研究

Research on the extraction of fragile wheels unearthed from Gujun site in Xingtang County,Hebei Province

考古发掘中经常遇到叠压复杂的脆弱质遗存,对这类遗存的提取是一个难点。以河北行唐故郡遗址CMK2五号车的左侧车轮遗迹为例,介绍了一种使用薄荷醇临时固型结合刚性支撑技术来提取较大脆弱质遗存的方法。通过精细发掘与预探测、车轮本体加固、薄荷醇临时固型、添加刚性支撑、整体提取、背面清理与加固、正面清理保护等技术流程,对左轮遗迹进行了成功提取和保护,其中发掘技术、刚性支撑技术、临时固型材料薄荷醇起到了关键作用。研究结果为此类较大平面脆弱质遗存的整体提取和保护提供了技术参考。

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.
