Comparison and Selection of Construction Plans for 1#Tunnel of Yintao Phase Ⅱ Zhuanglang Emergency Water Supply Project
The design section of 1#Tunnel of Zhuanglang Emergency Water Supply Project is small,the tunnel line is long,and the conditions for tunnel formation are poor.In order to select a reasonable construction plan,combined with the engineering geological conditions of Tunnel 1,the milling and excavation method was chosen as the best plan for the construction of Tunnel 1 in this project.This plan,under the premise of optimal construction period,has lower project investment,guaranteed quality,and lower construction risk.At the same time,it also provides a detailed introduction to the arrangement of tunnel working faces and branch tunnel arrangements,branch tunnel design,tunnel ventilation,and tunnel construction methods,providing method references for the construction of tunnels in this project and similar projects.
