To avoid cracks or collapse to precast concrete
segments in water transmission lines due to external environment or
construction quality defects, largediameter lined steel tiles are
required for reinforcement. A lined steel tile transport and adjustment integrated
machine is designed and manufactured to address technical construction problems
such as tight space between lined steel tile and inner tunnel wall, eccentric
structure of steel tile in longdistance
transportation, and high assembly accuracy requirement. Next, structural design
and systematic analyses are conducted on the clamping structure, transportation
correction system, and assembly and docking of the steel tiles, and optimal
schemes are proposed. Finally, the strength of the transport and adjustment
integrated machine is examined by finite element analysis. The results of the
analysis reveal the following: (1) The structural design is reasonable, the
strength is stable, and the functions of the machine meet relevant requirements
of site construction, which can provide a technical scheme for the longdistance transportation, assembling, and docking construction of
largediameter lined steel tiles in tunnels. (2) The
machine improves the transportation efficiency, assembly and docking accuracy
of lined steel tiles, and reduces the cost and construction difficulty.
