The invention discloses a large-diameter municipal pipeline simulation splicing device based on high-precision 3D scanning. The large-diameter municipal pipeline simulation splicing device comprises areinforced concrete rain sewage pipe section, wherein two ends of the reinforced concrete rain sewage pipe section are respectively provided with a reinforced concrete rain sewage pipe section socketand a reinforced concrete rain sewage pipe section socket; a pipe bottom rolling cylinder is arranged in the reinforced concrete rain sewage pipe section; A laser range finder is installed at the axis of the pipe bottom rolling cylinder, a telescopic rod with a scale is arranged outside the reinforced concrete rain sewage pipe section, a 3D laser scanner is fixed to the telescopic rod with the scale, a CCD imaging target block is installed below the telescopic rod with the scale, and a positioning module is arranged on the 3D laser scanner. High-precision 3D scanning can be carried out afteraccurate positioning to fin
