The invention discloses a portable assembled shield tunneling machine sleeper and solves the technical problems that an existing shield tunneling machine trolley sleeper is low in stability and is easy to deform. The sleeper comprises a motor vehicle channel steel sleeper beam (15); the top of the motor vehicle channel steel sleeper beam (15) is provided with two pairs of motor vehicle rail clamping grooves (18), pads are arranged between the left and right bottoms of the motor vehicle channel steel sleeper beam (15) and a first lining segment (2), lining segments of left and right sides of the motor vehicle channel steel sleeper beam (15) are provided with arc plates, and the arc plates are fixed to longitudinal segment connecting bolts through arc plate tail unit fixing sheets; shield tunneling machine trolley rail grooves are arranged on the tops of left and right vertical plates; the sides of the left and right vertical plates are movably connected to the sides of the motor vehicle channel steel sleeper beam (15) in a pressed manner. The shield tunneling machine trolley sleeper and a slag conveying motor vehicle sleeper can be assembled accurately and safely, the portable assembled shield tunneling machine sleeper can be assembled and disassembled in site particularly, and the sleeper material consumption is reduced.
