The measuring device for construction engineering management slides up and down inside the column through a second slider, thereby driving the telescopic ruler to extend and retract, thereby driving the connecting seat to move up and down, thereby driving the laser light to move up and down. Through the display screen, the position of the laser light irradiation can be seen, and the measured height can be obtained by the length of the telescopic ruler. This solves the problem that most of the existing technologies use tape measures for measurement. When measuring height, it is not very convenient to use the tape measure.
