How the plumb line is frozen using a zenit appliance
The measurements of the anti-aircraft Probe at one point on average are carried out in 3-4 minutes, and for six to eight stamps-in 30-40 minutes. Observation of one plumb line, including its descent and regulation in height relative to the price-trigger plates, lasts 6-7 minutes, and the determination of the formwork position of 7-8 plumb lines is carried out by 3-4 people for 1 hour 10 minutes.
The disadvantage of working with the anti-aircraft Probor is the need to observe from the bottom up, preliminary support for the safety of observations and the availability of skill in working with the device with the device.
