Ib theem kev tsheb ciav hlau yog ib qho cuab yeej ntxiv uas tso cai rau koj ua haujlwm geodetic hauv kev tsim kho, nrog rau siv hauv kev tshawb fawb geological lossis topographic.

Nrog kev pab los ntawm nws, qhov sib txawv ntawm qhov siab ntawm qhov av tau kho. Txoj kev tsheb ciav hlau theem yog lub dav hlau duab plaub nrog lub nplais tso rau ntawm nws, uas yog siv nrog ib qho kev faib nqi.

Ntau yam

Muaj plaub hom kev sib tw no:

  • ntoo rail nrog muaj peev xwm nthuav tawm;
  • telescopic;
  • fiberglass lath;
  • siab-precision invar.
  • theem rail

Kev piav qhia

Cov khoom niaj hnub tuaj yeem tsim rau cov qib digital thiab cov pa. Reikidigital yog siv rau qib uas tuaj yeem nyeem cov lej BAR uas tau siv rau saum npoo ntawm cov cuab yeej no. Nrog kev pab los ntawm cov cuab yeej zoo li no, qhov kev ncua deb ntawm lub cuab yeej thiab qhov sib txawv ntawm qhov siab yog txiav txim siab. Tsis tas li ntawd, cov cuab yeej no muaj kev kawm tiav ib txwm nyob tom qab, vim tias lawv tuaj yeem siv tau raws li qib yooj yim.

  • Leveling rail, ua los ntawm ntoo, folds hauv nruab nrab. Qhov ntev ntawm txhua ntu yog kwv yees li 1.5 meters. Ntoo slats hnyav dua li telescopic sawv daws yuav. Tab sis ntawm qhov tod tes, lawv muaj ntau txhim khu kev qha folding mechanism piv rau cov qhia analogue, uas muaj ib tug backlash nyob rau hauv lub mechanism kho khawm. Xws li ib tug leveling rail yog ib tug dielectric. Qhov no muaj tseeb thaum ua haujlwm ze ntawm cov xov hlau qhib thiab cov kab hluav taws xob siab.

  • Telescopic leveling rail nyob rau hauv ib tug niaj hnub tsim yog ua los ntawm cov ntaub ntawv sib xws li yas los yog txhuas, uas yog heev yooj yim mus use vim nws tsis tshua muaj hnyav. Lawv muaj ib theem puag ncig, uas ua rau nws muaj peev xwm muab cov cuab yeej no nruj nreem vertically. Feem ntau siv cov slats uas muaj qhov ntev ntawm 3, 4 thiab 5 m. Thaum folded, lawv muaj qhov ntev tsis tshaj 1.5 meters. Cov nplai ntawm cov khoom zoo li no yog siv rau ntawm ob sab (ntawm ib millimeter nplai yog muab tso rau - rau kev ua haujlwm ze, thiab rau lwm qhov - hauv daim ntawv checkers rau kev siv ntawm qhov ntev).
  • Fiberglass pas nrig yog siv hauv kev ua haujlwm nrog qib digital. Zoo li tag nrho cov khoom siv saum toj no, nws muaj qhov cim ob sab. Los ntawm ib qhosab, zoo li ib tug pa theem, nyob rau lwm yam - ib tug metric scale. Xws li lub tsheb ciav hlau yog ua los ntawm cov khoom siv dielectric hu ua fiberglass. Yog li ntawd, nws tuaj yeem siv nyob ze cov kab hluav taws xob siab.
  • Invar rails yog siv los ua qhov kev ntsuam xyuas thaj chaw siab. Ntawm no, qhov tseeb ntawm kev txiav txim siab cov cim tsis ntau tshaj ib millimeter. Nws lub cev yog ua los ntawm ntoo thiab npog nrog invar daim kab xev. Cov slats no yog ua nyob rau hauv ntev ntawm 3 m. Vim lawv yooj yim ntawm kev siv thiab lub teeb yuag, lawv nyob rau hauv zoo thov.

Result

Tam sim no koj paub tias tus neeg ua haujlwm theem yuav ua li cas. Topographers, cartographers, builders, miners paub siv nws li cas. Txawm li cas los xij, leej twg tuaj yeem kawm qhov txuj ci no. Qee zaum lwm lub npe rau cov cuab yeej no yog siv - kev tsim kho tsheb ciav hlau, lossis geodesic. Tus nqi ntawm cov khoom no nyob ntawm nws qhov loj thiab qhov tseeb ntawm kev faib.
