Application and Practice of Elastic Cabling System for Ancient and Famous Trees:Taking Ancient Michelia×alba of Sun Yat-sen Memorial Hall in Guangzhou as an Example
With the protection of ancient and famous trees receiving more and more attention,the management and protection techniques of the trees are also being gradually updated and optimized.At present,rigid propping is mainly used to protect ancient and famous trees with defects in China.However,long-term use of rigid propping will damage the adaptive ability of trees,which is not conducive to the mechanical balance of ancient trees.In order to reduce the problems caused by rigid propping,Sun Yat-sen Memorial Hall in Guangzhou adopted a'Cobra Cabling System'for two ancient Michelia×alba in the park to improve structural stability.Based on the results of risk assessment of the trees and the current situation,the technical design of the cabling system for branches at risk was carried out.Comparing the application of the cabling system before and after the strong storm brought by Typhoon Saola and Haikui,it was found that there was no dislodgement or deviation of cabling points on the trees,which verified the safety of the cabling system.
