| Abstract: | The drilling and blasting method to excavate a tunnel section with worse surrounding rock in a water diversion tunnel projet in the Jilin Province was adopted, and the unadhesive prestressed concrete lining was used in the tunnel section excavated by drilling and blasting method. The paper mainly introduces the construction process of this concrete lining, the manufacturing and installing of the reinforcement, steel twisted rope and the form of anchor cell, the installing ＆ disassembling of passing steel form carriage, the concrete construction and tensioning the steel twisted rope. |
