The concrete construction of high efficiency laser leveling machine, laser leveling machine used in concrete, large area floor construction, operation efficiency is greatly improved, consisting of about 6 workers in construction team, completed 300 square meters per hour paving work, the average class can complete 2500 to 3500 square meters, the project is especially suitable for tight, laying period the building area is large, high quality requirements.
Ground maintenance cost is greatly reduced, concrete laser leveling machine, applied to large area floor construction, reduce construction joints at the same time, it can effectively solve the ground hollowing, cracking, peeling, inequality, the floor maintenance cost is greatly reduced.
The coordinates of the origin of the frame coordinates of the laser leveling machine in the engineering coordinate system are determined. After determining the direction of the frame coordinate axis in the engineering coordinate system, the location of the coordinates of the frame coordinate must be completely determined, and the engineering coordinate o (g, h, K) of the coordinate origin is needed. As mentioned earlier, the relative position relationship between the frame axis and the longitudinal axis of the GPS tower is not changed by the distortion of the frame.
