上海古建筑日均“行走”10米 7500吨石库门建筑群完成归位

Core Viewpoint - The article highlights the successful completion of the relocation and restoration of the "Huayanli" stone gate building group in Zhangyuan, Shanghai, which is the largest group of stone gate architecture in China, emphasizing the balance between historical preservation and urban development [1][5][14]. Group 1: Historical Significance and Preservation - Zhangyuan has a history of over 140 years and is recognized as the largest and most well-preserved stone gate architectural complex in Shanghai, serving as a living museum of the city's history [1][7]. - The "Huayanli" building group consists of three stone gate buildings with a total area of approximately 4,000 square meters, showcasing exquisite decorative features and historical significance [8][10]. Group 2: Relocation and Restoration Process - The relocation process began on May 19, with the buildings moving at an average speed of 10 meters per day, utilizing 432 small walking robots to facilitate the movement [3][4]. - The buildings were temporarily fixed to their foundations and lifted using hydraulic jacks, allowing for the installation of walking robots that enabled the buildings to "walk" back to their original positions [4][10]. Group 3: Urban Development and Infrastructure - The relocation was necessary to protect the historical buildings from damage during underground construction, which aims to create additional municipal facilities and parking spaces [7][11]. - The underground space will provide over 300 new parking spots and facilitate transfers for three subway lines, integrating modern infrastructure with historical preservation [13]. Group 4: Future Prospects - After restoration, the historical buildings are expected to be transformed into a new commercial district and office spaces, contributing to the urban renewal efforts while maintaining the historical essence of the area [13][14]. - The approach of "repairing the old as the old" reflects Shanghai's commitment to balancing urban development with the preservation of its historical architecture [14].
