Support and reinforcement protection techniques for ancient trees in the Forbidden City from the perspective of cultural heritage
Based on the practice of supporting and reinforcing the protection of ancient trees in the Forbidden City, the reasons for supporting and reinforcing ancient and famous trees were analyzed, and the types and technical key points of supporting ancient trees, pulling fibers and reinforcing with iron hoop in combination with examples were summarized. The reasons for support and reinforcement were hollow rot and splitting of the ancient tree body, tilting and crown deviation, increased load of the tree body, and shallow root distribution. The technical measures for the protection of ancient trees in the imperial courts of the Ming and Qing Dynasties included support with double “π”-shaped fir poles and multiple “T”-shaped fir poles. The support and reinforcement of ancient trees included 3 types: hard support, fiber drawing reinforcement and iron hoop reinforcement. Among them, hard support could be further classified into single-column“T” type, double-column “π” type and multi-column persimmon type support. Choose elastic support heads in a timely manner to promote the adaptive growth of ancient trees; the forms of cable bracing reinforcement could be selected as single lead type, triangular type, radial type and box type according to the morphological characteristics of the branches to be protected in the crown, and materials such as steel wire rope, steel bar or steel pipe could be chosen according to the thickness of the branches. Split tree trunks could be reinforced with iron hoops. This article provides a reference for the protection of ancient trees in cultural heritage sites.
