Road cross-section rulerUsage:

(1) Place the cross-sectional ruler on the measuring section and place the two end supports on both sides of the measuring lane.

(2) Every 20 centimeters along the cross section ruler, stand the ruler vertically on the road surface, and measure the distance between the top surface of the cross section ruler and the road surface with a straight eye, accurate to 1 millimeter. If the Z-high or Z-low point of the cross section is clearly not at the measuring point, the distance from that point should be added.

(3) Record the measurement readings, provide a cross-sectional diagram, and connect the Z to form a smooth cross-sectional line.

(4) When it is not necessary to measure the cross-section and only the Z large turnout needs to be measured, a cross-section ruler without legs can also be used to visually determine the position of the Z large turnout on the road surface and measure it with a ruler.
