Trackless flat car for TBM, maneuvering TBM and construction method

The invention belongs to the technical field of tunneling equipment, and particularly discloses a trackless flat car for a TBM, the motorized TBM and a construction method. The TBM construction method mainly comprises the steps that the main machine and the modularization are arranged on the trackless flatcar in a matched mode to achieve rapid transfer in a TBM whole machine hole, the starting device is arranged on the trackless flatcar to achieve rapid starting of the vehicle-mounted main machine, and after tunneling is completed, the main machine and the modularization are matched to advance or retreat to the trackless flatcar to achieve transition operation. The motorized TBM is used for implementing the construction method and comprises the trackless flat car. The problems that an existing TBM is poor in flexibility in the underground complex cavern group construction process and long in construction period consumed by multiple times of disassembly, assembly and transfer and starting are solved. 本发明属于掘进设备
