The invention relates to a visual construction device for sprayed concrete. The visual construction device comprises a leveling device, a measuring device, a control device and a projection device, wherein the leveling device is used for obtaining coordinates of the leveling device and sending the coordinates of the leveling device to the control device; the measuring device is used for detecting actual absolute coordinates of all points on the tunnel wall and sending all the actual absolute coordinates to the control device. The control device is used for dynamically calculating the distance difference between each point on the tunnel wall and a point corresponding to a target contour surface according to a preset tunnel shotcreting construction target contour surface and a plurality of actual absolute coordinates, and controlling the color of each point projected by the projection equipment on the tunnel wall according to each distance difference; and according to the coordinates of the leveling device and
