Lattice angle steel telecommunication towers ua haujlwm pabcuam tseem ceeb rau kev sib txuas lus hauv xov tooj. Lawv cov qauv tsim kev pab cuam lub neej nyob ntawm 30 txog 50 xyoo, thaum lub sijhawm ua haujlwm tiag tiag yog sib koom ua ke los ntawm plaub yam tseem ceeb: xaiv cov khoom siv, qhov chaw ib puag ncig, kev tsim qauv, thiab kev ua haujlwm & kev tshuaj xyuas.
Kev tiv thaiv - kev kho corrosion ntawm steel tsim lub hauv paus ntawm ntauwd durability. Standard kub-dip galvanized lub kaum sab xis steel cia siab rau kev txi zinc txheej los tiv thaiv xeb. Los ntawm qhov sib piv, steel nrog nyias zinc txheej lossis tsis yog - cov qauv tshwj xeeb yuav raug kev poob qis, ua rau muaj kev poob qis hauv kev thauj khoom - cov kabmob muaj peev xwm. Ntsev pos huab nyob rau hauv cov ntug hiav txwv dej thiab tshuaj khib nyiab roj nyob rau hauv industrial zones zoo heev ua rau corrosion. Cov pej thuam zoo ib yam uas tsis muaj kev txhim kho los tiv thaiv- kev kho corrosion tsuas tuaj yeem ua haujlwm ruaj khov rau 15 txog 20 xyoo hauv cov cheeb tsam hnyav, qhov zoo tshaj plaws galvanized steel ua kom ruaj khov rau ntau tshaj 40 xyoo nyob rau hauv me me suburban inland ib puag ncig.
Kev tsim qauv tsim qauv tiv thaiv cua load, daus siab thiab seismic quab yuam. Plaub -legged lattice thav duab muaj qhov sib npaug ntawm kev ntxhov siab thiab kev nyab xeeb txaus, nrog rau kev nkag mus rau kev saib xyuas kom yooj yim tom qab tu. Cov qauv tsim yooj yim uas raug cuam tshuam los ntawm kev ntxhov siab los ntawm huab cua huab cua yog qhov ua rau muaj kev pheej hmoo xws li xoob bolts thiab deformed Cheebtsam.
Kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua yog qhov tseem ceeb rau kev ua haujlwm ntev ntauwd. Kev tshuaj xyuas tag nrho raug pom zoo txhua txhua peb xyoos rau thaj chaw zoo tib yam, thiab txhua ib mus rau ob xyoos rau cov chaw nyob hauv ntug dej hiav txwv thiab chaw lag luam. Cov kws kho mob yuav tsum ceev cov khoom sib txuas, hloov cov corroded fittings thiab ntshiab plua plav thiab corrosive deposits ntawm qhov chaw. Kev puas tsuaj me me yuav ua rau muaj kev puas tsuaj ntau zuj zus txhua xyoo yam tsis muaj kev saib xyuas niaj hnub, ua rau luv luv lub pej thuam kev pabcuam.
Muaj cov xwm txheej ua pov thawj tias cov yees tsim los ntawm lub teb chaws -tus qauv kub-dip galvanized steel, tailor- tsim los rau cov chaw hauv cheeb tsam thiab khaws cia ib ntus tuaj yeem ua haujlwm tau ntau dua 50 xyoo. Ntawm qhov tsis sib xws, cov pej thuam ua los ntawm cov khoom siv tsis zoo, siv nyob rau hauv ib puag ncig hnyav thiab tsis muaj kev saib xyuas tsis tu ncua yuav tsim kev phom sij ua ntej ntawm lub sijhawm thiab yuav tsum tau rhuav tshem thiab rov tsim kho sai. Thaum xaiv cov yees, cov tswv lag luam thiab cov neeg tsim kho vaj tsev yuav tsum kho cov kev daws teeb meem los tiv thaiv -corrosion raws li qhov chaw corrosion theem thiab tsim kom ntev - lub sij hawm tshuaj xyuas mechanisms txiav tag nrho - lub neej hloov cov nqi.
