Research on Rapid Construction Technology of Long Distance Tunnel Pavement Concrete
For tunnels with Class Ⅱ and Ⅲ surrounding rock sections in long-distance tunnels,only pavement concrete is applied,while Class Ⅲ(special section of surrounding rock),Ⅳ,and Ⅴ surrounding rock sections are lined with full section reinforced concrete.The geological surrounding rock distribution is uneven and discontinuous,and the proportion of pavement concrete sections is relatively large.In order to solve the problem of high breakpoints in the concrete lining of deep buried long-distance tunnels and accelerate the construction progress of long-distance tunnel pavement concrete,research is conducted on the operation points and related control measures of rapid construction methods for long-distance tunnel pavement concrete with uneven distribution,discontinuity,and a large proportion of tunnels.
