机械切割在土遗址搬迁保护中的应用研究

Research on the application of machine cutting technology to relocation and protection of earthen sites

传统的人工掏挖装箱搬运分块过多,为尽量减少对土遗址本体的干预,本研究提出了采用机械切割方式对土遗址进行分块的方法。以上海广富林文化遗址"F12房址"搬迁保护工程为背景,设计了机械切割设备,试验初探了机械切割在土遗址搬迁保护中的应用,对水平切割速度、牵引力及设备等关键技术进行了针对性研究,并改进机械切割方案,成功应用于房址整体搬迁保护工程。研究表明:机械切割技术可应用于土遗址搬迁保护,有效减少分块数日,降低搬迁作业对遗址的损伤,可为相似的文物保护工程提供有益借鉴。

To minimize the interference and damage toearthen sites during relocation, a partition method for machine cutting is proposed for the first time, with consideration of traditional small - block artificial digging and partitioning technology. In connection with relocation of the Guangfulin euhure site ＂F12 site＂, special cutting machinery was designed and produced. This paper presents a preliminary study on the application of mechanical cutting in earthen site relocation projects with a particular focus on key technology, such as horizontal cutting speed, tractionf- orce and mechanical machinery. This technology was successfully applied in the relocation of ＂F12 sites＂ project. The results show that machine cutting technology can be applied to site relocation and protection. It call reduce number of the partitionsand damage during relocation without obviously changing the earthen site. This work provides support and reference for similar projects.
