Perpendicularity measuring device for pier template

According to the perpendicularity measuring device, before the pier template is closed, the laser device mechanism is installed on the pier template, the floating ball floats above the partition plate of the water tank, the laser device always keeps the light outlet of the laser device downward due to the gravity effect, and the vertical light can provide reference for measuring the perpendicularity of the pier template, so that the perpendicularity of the pier template is measured. Moreover, the laser mechanism only needs to be simply, quickly and simply installed on the bridge pier template, and the laser can adjust the posture to be vertically downward by means of the gravity of the laser without excessive correction operation, so that the installation and debugging work of workers can be simplified; the laser device mechanism does not need to consider the influence of external factors (such as wind power factors) on the measurement result, the detection precision is high, the sliding block of the scale me
