Laser vertical collimator is using optical collimation principle, the collimation axis coincides with the visible laser produced a plumb line to align the reference point to determine location of equipment, often used as a control tool axis measured up to vote. In the construction and installation of high-rise buildings, towers, chimneys, elevator, large institutional equipment and other occasions has been widely applied. In my past experience in construction is the case, but if a big circle to die, you'd better take the machine over time professionals corrected it. (Best not to adjust the minimum circle or circle) there is not a layer of a traditional print ... when vertical discharge line: Surveying Engineering, extensive construction, water conservancy, transportation and road works, cadastral measurements and real estate : large-scale industrial production and construction of equipment installation, bridge, dam deformation observation, geological disaster monitoring, athletics and other sports. Specific applications: Control Measure: banded terrain and hidden areas, such as line measurement and control of urban control measurements, using total station basic measurement functions - Traverse, laid the corner mesh wire mesh and very flexible, easy observation, high precision . And GNSS products (handset, RTK) with the use of laser marking instrument calibration, distribution network in the form of a more flexible, more convenient observation of laser marking instrument calibration, accuracy is more reliable. Plane and elevation control can be carried out simultaneously with the Triangle elevation measurements can replace four leveling measurements. Topography: Using total station program for three-dimensional coordinate measurement measurement functions, side intersection, resection, measuring earthworks etc., not only simple, but also fast, high precision, and can be controlled simultaneously measure and detail point measurement . Total Station with the computer can be, plotters connected to form mapping system laser marking role inside and outside the industry through the integration of transport equipment, thus greatly improving the quality and efficiency of topographic mapping. Loft Project: Using total station stakeout position measurement function can be designed better buildings, roads, pipelines and other facilities, according to the drawings quickly and accurately to the construction site survey and design field, as the basis for construction; especially some modeling complex, demanding, large-scale building (structure) building materials and so on. Deformation Monitoring: Monitoring the winning line in the dynamic deformation observation instrument, geological disasters buildings, using total station coordinate measurement capabilities of three-dimensional coordinates of the deformed part of real-time monitoring, can grasp the deformation law to protect the structural safety.
