The Grouting Technology of Large-Section Highway Tunnel in Water-Rich Karst Formations

Zhou, Chao Yue / Fang, Yong / Fu, Ya Peng / Cui, Ge

It is a challenge to deal with karst in the construction of large cross-section tunnel. Under the background of Shuangbei Highway Tunnel, a new kind of grouting technology is introduced. According to hydrogeology, field tests are carried out to select grouting materials and proportion of mixture. Combined with the project practice, grouting construction technology is discussed such as grouting equipments, grouting parameters, operation technique, grouting ending standards. It has been proved that the technology is effective in tunnel construction.
