The integral or partial castinsitu middle partition wall in conventional shield tunnels has
disadvantages, including low construction efficiency, complicated procedures, and
poor stability. Hence, an intelligent control system is developed based on the
construction technology of the middle partition wall and the structural form of
supporting installers, relying on the tunnel project of Lot JCXSG11 of the airport connecting line project of Shanghai Rail Transit
City Line. In this study, the design process and functional modules of the
control system are analyzed in detail, from the aspects of overall framework
design, process design, function module design, and control and detection
algorithm. The main structure and working steps of the middle partition wall
mounting machine are then introduced. Furthermore, the design method and
implementation effect of the intelligent control of the center hole positioning
of the visual camera identification and the multisensor information fusion
positioning of the double sixaxis manipulator are
emphasized, ensuring the assembly attitude and control precision of the middle
partition wall installer. The field test results reveal that: (1) The control
system can drive the installation machine to better complete the specified
action and realize the design function. (2) The control system was used to
assemble 360 middle partition walls, the average assembly time of each middle
partition wall was controlled about 38 min, which is less than the design time,
and the assembly accuracy was controlled within ±3 mm.
