With the continuous improvement of urban infrastructure,the excavation and support construction of cables,transportation,and ventilation shafts have become increasingly important.This type of vertical shaft not only carries the task of laying and protecting cable lines,but also takes into account the functions of transportation channels and ventilation.The complexity and safety requirements of its construction technology are high.In actual construction,it is necessary to select appropriate construction methods and support types based on specific engineering conditions,and strictly control construction quality and safety.This article aims to conduct in-depth research on the excavation and support construction technology of cable and transportation and ventilation shafts,providing theoretical reference and practical guidance for related projects.
