Abstract

As a key national project, a newly built plateau railway features a large proportion of tunnels and high construction difficulty. To reduce the voids in the secondary lining of tunnels and address issues such as ineffective vibration of the vault, vault voiding, and the inability to monitor the casting status during tunnel lining construction with ordinary lining trolleys, a new smart lining trolley with large clearance that integrates functions such as vibration, automatic casting, and pressure monitoring has been developed. This was achieved by combining the functional design of the new smart lining trolley, comparing traditional construction techniques, and introducing information-based and intelligent design concepts. Through simulation calculations using finite element software modeling, it is verified that the structural stiffness, strength, and other performance parameters of the smart lining trolley meet the technical design requirements.
