The section from Shangmadun Station to Donglin Square Station has dense buildings along the route, as well as numerous pipelines and conduits; the shield tunneling machine needs to cross railways and rivers, making construction quite difficult.

To ensure the "Qihang" shield tunneling machine launches on schedule, the project department for Wuxi Metro2Line10bid section of Guangdong No.2 Hydropower Bureau, together with the company's technical department, carried out a series of activities to meet milestones and overcome difficulties, and conducted multiple expert reviews and demonstrations of the shield tunneling construction plan, providing strong technical support for the smooth launch and excavation of the shield tunneling machine.
