Ib qho ntxiv, lawv cov yooj yim ntawm cov ntaub thaiv kev ua rau rau cov qauv kev cai, sib piv ntawm cov chaw ua haujlwm aradium-style thaum ntsib kev nyab xeeb thiab kev xav tau.
Lub teb chaws Middle East siv h - ci rau megapsects?
Lub tebchaws Middle Eastern Mas as Tebchaws Asmeskas Emirates (UAA), Qatar, thiab Saudi Arabia Siv h {mi} ci rau megaps. UAE, tshwj xeeb Dubai thiab Abu Dhabi, tso cai rau h- cov kab mob loj, siab} sawv, thiab cov qauv sib tw. Qatar siv h - ci nyob rau hauv lub ntiaj teb khob {}}} cov dej num muaj cov dej num (chaw ntiav pw) thiab lub nroog tshiab. Saudi Arabia lub zeem muag 2030 megapretject (nom nroog, Riyadh Metro) thiab cov chaw tsheb thauj mus los hauv lub hom phiaj los ua kom muaj kev lag luam ntau dua thiab cov chaw hauv nroog loj.
Dab tsi yog qhov sib txawv ntawm qhov loj ntawm h - cov kab teeb tau siv rau cov plag tsev muaj kev lag luam thiab cov plag tsev nyob hauv tsev?
H - kab teeb rau kev lag luam cranes muaj ntau dua li cov plag tsev nyob hauv tsev. Crane h - Beams muaj qhov siab feem ntau tshaj li 400MM ({} Thaj chaw hauv pem teb h- Beams me dua, nrog h100}} hli ({21}} mm) kom ris lub teeb rau kev tsav tsheb (} Qhov loj me qhia txog loads cov kev xav tau yuav tsum tau- Cov plag tsev ua ntej chaw ua haujlwm thiab tus nqi- ua hauj lwm zoo.
Dab tsi zoo ua h - kab teeb muaj nyob rau hauv cov nqe lus ntawm tus nqi ntawm tus nqi- ua hauj lwm zoo dua cov pob zeb ua tau zoo tshaj?
H - Beams muaj ntau dua tus nqi -}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} Siv cov kab teeb ciav hlau ntau yam. Lawv lub cev yuag sib zog txo cov nqi thauj mus los thiab cov xuab moos me me thiab cov xuab moos tsawg dua, tsis zoo li cov kab mob hnyav hnyav, tsis zoo li cov kab mob hnyav. H - Beams tau siv sijhawm sai: lawv yog prefabricated tawm {}} Xav tau lub sijhawm thiab cov nqi zog). Nyob rau hauv ntev -}} niece} Beams siv cov khoom lag luam tsis muaj peev xwm ua tiav cov khoom lag luam zoo ib yam li cov nqi qis dua. Ib qho ntxiv, h - kab teeb tau yooj yim dua los hloov kho lossis kho cov nqi kho mob yog feem ntau kim thiab sijhawm {14} {} noj.
Txoj kev kho deg li cas ntawm h - kab teeb no cuam tshuam rau lawv corrosion tsis kam?
Nto kho tau ntau dua los txhim kho h - nqaj 'corrosion tsis kam. Galvanization (kub {- dauv txheej zinc uas ua rau cov txheej txheem tiv thaiv txawm tias cov chaw ib puag ncig (thaj chaw ntug dej hiav txwv (chaw ntawm ntug dej hiav txwv, cov chaw ua haujlwm). Anti -} Corrosion Pleev xim (epoxy, polyurethane) tsim cov barrier tiv thaiv ya raws nrog kev lag luam teeb tsa nrog kev siv tshuaj. Rau cov mob huab (ntug dej hiav txwv), kev sib txuas ntawm galvanization thiab xim muab rau ntau kev tiv thaiv. Yog tsis muaj kev kho, h - beams (carbon hlau) xeb (ntsev ib puag ncig, ua rau cov qauv dej qab. Txoj kev kho kom zoo txuas ntxiv lub neej ntawm 10 - 15 xyoo (tsis kho) rau}}, txo cov nqi thiab tu nqi.
