At present, the transport and assembly of lined steel
pipe in tunnel is characterized by large construction difficulty, low efficiency
and low assembly accuracy, which needs prelaid track. Hence, in order to suit
the rapiddeveloped pipe laying of longdistance water
diversion project, a lined steel pipe transportation and adjustment integrated
machine in tunnel is designed based on existing lined steel pipe transportation
and assembly technology and the characteristics of Hexi Branch Line project.
The machine has the advantages of convenient assembly and disassembly, high
construction efficiency, high automation and simple assembling process, which
does not need prelaid track. And then the finite element analysis is carried
out on the structure of the machine, the key components and the dynamic system
of the walking mechanism are analyzed, and internal structure and design scheme
of the machine are optimized to ensure reasonable structure and safe and stable
operation. The applicable results of the machine to Hexi Branch Line project
show that the steel pipe transportation is stable and reliable with high
assembly precision, construction efficiency and quality, which can provide a
new technical solution for the safety control, quality control, scheme
feasibility and cost control of lined steel transportation and adjustment
integrated machine production process.
