Tree Transplanting Method Based on TRU Detection and Top-Tube Soil Platform Bearing Base

This study addresses the technical needs of assessing root damage and diagnosing tree health during ancient tree transplantation. By utilizing root detection devices (Tree Radar Unit, TRU) and elastic wave tree tomography (Picus-3 Sonic Tomograph), it obtains data on root distribution and internal trunk damage rates, which are then used to design transplant soil block dimensions and pre-transplant tree protection and restoration plans. This provides data support for the pipe-jacking soil block transplantation method. Taking the Guangzhou Baiyun International Airport Phase III Expansion Project as a test case, precise pipe-jacking cutting and steel railing enclosure are implemented with the support of root and internal trunk data to create structurally stable and highly protective soil blocks that meet lifting and transportation requirements. Practical results demonstrate that this method effectively preserves root integrity and tree safety, achieving a 100% transplantation survival rate and reducing the transplantation cycle by over six months. These findings highlight its high applicability for transplanting ancient and renowned trees, as well as their subsequent resources, offering significant theoretical and practical value in promoting urban ecological culture and fostering harmonious coexistence between humans and nature.
