description The utility model discloses a section limit measuring device for urban subway construction, relates to the field of section limit measuring devices, and provides the following scheme aiming at the problems that the existing section limit measuring device is inconvenient to carry and move and is poor in measuring efficiency. The device comprises a bottom plate, a first screw rod, a section limit measuring device, a limiting plate and rotating plates, the surface of the first screw rod is sleeved with a first threaded cylinder in a threaded mode, the outer side face of the first threaded cylinder is rotationally sleeved with a rotating cylinder, and rotating rods are rotationally connected between the left side and the right side of the rotating cylinder and between the rotating plates on the left side and the right side of the rotating cylinder. The rotating plates on the two sides are rotationally connected with second threaded cylinders and fixedly connected with limiting sliding cylinders correspondingly, a
