The invention provides a TBM (Tunnel Boring Machine) integral type track bracket and a TBM motor driven and integral track bracket stepping method. The track bracket comprises a front end integral type track bracket and a rear end integral type track bracket. The stepping method comprises the steps of: constructing a preparation hole and a starting hole; constructing concrete of an integral type track under layer; carrying out other preparation works including: splicing holes, hardening a site, paving an integral type track, processing the integral track bracket and assembling and debugging aTBM; carrying out construction preparation works; carrying out TBM stepping works, one circle of which includes: laying a rear supporting leg down to the bottom surface of the concrete, moving the front end and the rear end integral track brackets ahead, dragging a TBM stepping host computer to step, extending a rear matched drawing oil cylinder; locking walking wheels of the front end and the rear end integral track brackets by using a positioning clamp; retracting the rear supporting leg; contracting the rear matched drawing oil cylinder to drive a rear match to move ahead; installing an inverted arch prefabricated section for paving the track, and carrying out slip casting on the prefabricated section. The TBM integral type track bracket and the TBM motor driven and integral track bracket stepping method have the advantages of short construction period and high speed.
