Los ntawm kev txheeb xyuas thiab muab piv rau tus ntoo khaub lig-sectional zog ntawm steel ncej, lub annular cross-section qhia qhov kev ntxhov siab zoo tshaj-cov yam ntxwv ntawm cov kabmob, ua raws li ntu hexagonal, thiab tom qab ntawd ntu dodecagonal. Qhov ntau sab, qhov zoo dua qhov kev faib tawm kev ntxhov siab thiab cov khoom siv qis dua, tab sis ntau dua qhov kev ua haujlwm nyuaj.
Due to the gradually changing wall thickness of the steel poles, they need to be divided into several sections. The number of flanges in a single pole should not exceed four. However, this is limited by transportation and the processes of molding and hot-dip galvanizing. Therefore, the length of each pole section should ideally be around 10m. When the wall thickness is large (>22mm), qhov ntev ntawm ntu yuav tsum raug txo kom tsim nyog raws li kev tsim cov cuab yeej ua haujlwm; txwv tsis pub, nias yuav ua tsis tau.
Tus qauv tsim yuav tsum xav txog tej yam yuav tsum muaj xws li kev tswj dej nyab, tiv thaiv hluav taws, tiv thaiv cua, thiab tiv thaiv dej khov. Piv txwv li, nyob rau hauv cov ntu hla los yog ze cov dej ntws, cov yeeb nkab steel ncej thiab nqaim- cov pej thuam hauv paus yuav tsum tau siv, nrog lub hauv paus pawg qhov tob txog li 12 meters los txhim kho kev tiv thaiv kev yaig thiab cuam tshuam.
Thaum lub Plaub Hlis Ntuj xyoo 2026, Lub Xeev Grid Beijing Hluav Taws Xob tau ua tiav qhov kev tshaj tawm -kev puas tsuaj hloov kho rau daim phiaj hluav taws xob hauv plaub cheeb tsam ntawm sab qaum teb Beijing. Hauv ntu hla lossis ze cov dej ntws, 257 siab- cov ncej muaj zog, suav nrog cov kav hlau kav hlau thiab nqaim- cov pej thuam, tau siv, thiab cov cuab yeej siv hauv paus tau tob los yog tsa, txhim kho kev tiv thaiv dej yaig thiab cuam tshuam. Piv txwv li, raws li 10kV Liuliang Road hauv Liulimiao Lub Zos, Huairou District, txoj kab uas hla ntawm cov tshiab tsim steel yeeb nkab ncej hauv paus pawg tau nthuav dav mus rau 1.8 meters thiab qhov faus qhov tob mus txog 12.2 meters, nrog txhua lub hauv paus siv ze li ntawm 1900 kg ntawm steel reinforcement thiab 40 cubic meters ntawm pob zeb. Hauv Cheeb Tsam Miyun, 203 pawg ntawm lub nkoj- zoo li cov piers tiv thaiv tau tsim kho tshiab rau cov dej- hla thiab dej- cov seem uas nyob ib sab, txhim kho lub hauv paus ruaj khov ntau dua 60% piv rau cov piers tiv thaiv ncig.
Nruam optimization kuj tau ua nyob rau hauv cov qauv tsim. Piv txwv li, cov yeeb nkab steel ncej rau peb - cov kab xaim hluav taws xob tau ua tiav kev sib koom ua ke ntawm nkhaus caj npab thiab crossarms, ua tiav kev sib npaug ntawm ob sab, txo lub sijhawm khoov los ntawm tus ncej lub cev, thiab pab txo qis tag nrho qhov siab ntawm cov yeeb nkab steel ncej.
Tus tsim yuav tsum coj mus rau hauv tus account lub installation tej yam kev mob. Cov xwm txheej geological yuav tsum tau tshawb xyuas ua ntej kev teeb tsa. Tsis muaj leej twg raug tso cai los sawv ntawm qhov chaw teeb tsa thaum lub sijhawm teeb tsa. Cov neeg ua haujlwm yuav tsum ua tib zoo mloog thiab txhua lub tuam tsev yuav tsum koom tes ua ke.
