Combining with cast-in-situ box girder bridge engineering of Niulangguan overpass on Nanhuan line of Guiyang city highway as an ex-ample,in light of its local geological conditions,the article puts forward machine-made sand vehicle pumping concrete scheme,and continuously optimizes its mixing proportion design. As a result,it guarantees engineering quality,shortens construction duration,and reduces construction cost.
