When the marking is completed, the insertion rod 12 is lifted up, the L-shaped plate 1 is pushed, and the universal wheel 6 moves on the road surface, the roller 9 moves along the side of the road edge, the roller 9 drives the rotating shaft 8 to rotate, the rotary encoder 2 inputs the number of pulses to the PLC controller 4, the PLC controller 4 obtains the moving distance according to the number of pulses, and displays the moving distance on the display screen 3, when the construction personnel observes that the moving distance displayed on the display screen 3 is equal to the interval between the adjacent two to-be-installed wave-shaped guardrail columns, the insertion rod 12 is pressed down to mark, and the marking of the position of the next to-be-installed wave-shaped guardrail column is completed. The above operation is repeated to mark the positions of the subsequent to-be-installed wave-shaped guardrail columns.

[0028] Preferably, the handle 16 is fixedly connected to the upper surface of the transverse plate 102, so as to facilitate the construction personnel to hold the handle 16 to move and operate.
