Abstract

The invention relates to the technical field of engineering construction, and particularly discloses a pavement flatness measuring device for engineering construction, which comprises an eight-wheel instrument for measuring the flatness of a pavement; the detection mechanism is installed in the eight-wheel instrument support, and the detection mechanism detects the friction coefficient of the road surface before the device runs; the road surface friction coefficient is detected in advance through the adjusting mechanism, the adjusting mechanism dynamically adjusts the position of a pressure sensor and the ground clearance of a detection wheel according to the friction coefficient, and a fixed motor is started to drive a rotating ring to rotate through a rotating roller and a synchronous belt to drive a second lead screw to rotate; the movement of the second moving member can drive the eight-wheel instrument supporting seat to move up and down, thereby adjusting the ground clearance of the detection wheel, effectively compensating the data deviation caused by the wear of the detection wheel, and improving the accuracy and stability of the measurement result.
