激光全站儀故障處理要點

地鐵盾構法隧道施工激光全站儀故障處理要點有哪些?
What are the main points of laser total station fault in metro shield tunnel construction?
a.激光全站儀被水淋了,不能正常工作,處理辦法是把全站儀卸下來,擦干凈涼干;
A. Laser Total Station water has been poured, can not work properly, the way to deal with the total station is removed, wipe clean, cool dry;
b.全站儀的氣泡偏了,VMT顯示姿態偏差變大,處理辦法是把全站儀再次整平,然后做一下全站儀方位檢查,如果檢查超限,就需要重新測定激光站的坐標,千萬不要在不測定變動后的激光站坐標的情況下重新定位測量。這樣只能誤導VMT導向系統給出錯誤導向。如果檢查未超限,就直接重新整平儀器,重新定位測量;
The B. total station bubble partial, VMT shows the attitude deviation becomes larger, the approach is the total station again and then do some leveling, total station check, check if the overrun, it needs to coordinate measuring laser station, do not do not measure changes after laser station coordinates re positioning measurement. This can only mislead the VMT guidance system, giving error oriented. If the inspection is not out of bounds, re leveling the instrument directly and re positioning the measurement;
c.全站儀在定位時沒有關掉全站儀的電源,定不了位,處理辦法是把全站儀的電源關掉,重新啟動定位程序;
C. total station in positioning, did not turn off the power of the total station, and can not determine the location, the way to deal with the total station power is turned off, restart the positioning procedures;
d.全站儀找不到ELS靶,處理辦法是首先看全站儀與ELS靶之間的空間有沒有障礙物擋,如果有,將其移開。如果還收尋不到,就人工測量出激光站至ELS靶的方位,手動輸入到激光站編輯器里的方位當前值里。
D. total station can not find ELS target, the treatment is to see the space between the total station and the ELS target, there is no obstacle, if there is, remove it. If not found, manually measure the position of the laser station to the ELS target and manually enter the current value in the orientation of the laser station editor.
