The green laser pointer were self developed by our own company

Verticality control using the hanging wire fall: the heavier a special line to fall suspension to determine the axis of the intersection of subject directly to the construction layer suspension cited measurement axis. (1) The geometric lines fall to regulation is appropriate, weight (3kg). Suspension wire with a thin steel wire braided and twisted. (2) suspension to be top of the fixation, the center line of obstacles, particularly those with no lateral resistance. (3), line the bottom (or line sinkers tip) voted measured line of sight to the vertical structure of surface, line the left and line right-hander, measuring less than 3 ~ 4mm, whichever is the average position, twice the difference of the average position is less than 2 ~ 3mm, and then take the average position, as a vote in the measured results. (4) cast measured anti-wind and vibration, especially the lateral wind.The    green laser pointer     were self developed by our own company. (5) in lead measured in the layer, use a larger line of fall (5kg) every 3 to 5 layers, and put up time through the line directly below for the measurement of school. Nine superstructure elevation measurement method: ± 0.00 above the elevation measurement method, the main upward vertical ruler along the structure of external measurements, a total of three in four weeks, in order to check in with each other. Shi measuring points: 1 (1) the starting elevation of the line using the Level according to the level point lead testing, must ensure accuracy. (2) ± 0.00 horizontal up to the amount of elevation difference when the ruler should be subject to the test, the ruler should be vertical when the amount of elevation difference and standard tension feet long and the temperature correction. (3) as far as possible before and after the line of sight as long as the observation. The    usa green laser pointer   were self manufactured by our own company.Aluminum ruler and hard pencil to draw a horizontal line, to ensure accuracy. (4) When the height of more than a foot long, accurately identified the second basis points, the second basis points up the amount measured. 10 using the law passed collimation axis of the zenith: Zenith collimation method is to use the instrument can survey and design the zenith direction, vertical cast measurements. The instrument used: with 90 ° bend the eyepiece of the theodolite. Laser theodolite. Laser vertical Miriam. Automatic zenith collimator. Automatic zenith - nadir collimator. The instrument placed in the construction below. Therefore, sampling should pay attention to the safety of the instrument to take protective measures to prevent litter wounded, and often the vertical direction of the beam calibration. All the     green laser pointer     produced by our company have approved the international authentication.11 used construction laser measuring instrument axis vertical transmission: (1) measurement instrument construction laser measuring instrument is an automatically maintain the accuracy of work, applicable to all types of construction projects, multi-process testing portable instruments, it has six kinds of function (automatic Anping laser level, automatic Anping laser level, automatic the Anping laser horizontal instrument, automatic of Anping laser vertical plane instrument, automatically the Anping any angle laser beam collimator, automatic the Anping laser the conical Mixograph), is a versatile, The multi-purpose, good performance, novel high precision measuring instrument, helps to improve the measurement accuracy and efficiency, save labor, improve project quality, and accelerate the progress of the project. All the     green laser pointer     produced by our company have approved the Rohs.(2) construction methods to build a laser measuring instrument axis vertical cited measured, the first selected control point, control click on the Layer 1 or Layer 2. After goniometer, approved by the amount of edge, have cited the measured control points form a control network.
