It is suitable for track precision measurement and sleeper precision adjustment of all laid track control network (CPⅢ) lines. At present, it is mainly used in the construction process of high-speed rail and subway double-block ballastless track, and can also be used for subway floating plate and steel spring shock absorbing plate construction precision measurement and precision adjustment.
SGJ-T-DT-2 is a measuring device for measuring the internal and external geometric parameters of the track simultaneously. The equipment has built-in gauge gauge, inclination sensor, odometer and other high-precision sensors, and has a complete acquisition, storage and wireless communication system, which can form a real-time measurement system through industrial computer and high-precision automatic total station. Main measurement contents: gauge, level, track direction, height, positive vector, distortion (triangle pit), gauge change rate, the plane (transverse) and elevation (vertical) deviation of track center line and left and right rail relative to the design line position.
