Lub thav duab hlauCov tsev ua lub luag haujlwm tseem ceeb hauv kev tsim vaj tsev niaj hnub. Cov neeg tsim kho vaj tse xaiv cov hlau rau cov tsev lag luam, kev lag luam, thiab cov tsev nyob loj. Kev lag luam thoob ntiaj teb ntawm cov qauv hlau tau txog USD 93.2 billion hauv xyoo 2023. Cov kws tshuaj ntsuam xyuas kwv yees tias yuav loj hlob mus txog USD 145.1 billion txog xyoo 2032, ntawm qhov kev loj hlob txhua xyoo ntawm kwv yees li 5.04%. Qhov kev loj hlob no qhia txog kev xav tau ntau rau kev tsim kho hlau.
Daim Ntawv Thov Cov Tsev Hlau Ncej
Lub thav duab hlauCov tsev tsim nyog rau ntau yam kev siv. Cov kws kes duab vajtse tsim cov chaw ua haujlwm siab, cov tsev rau khoom, cov chaw tsim khoom, cov chaw yuav khoom, thiab cov haujlwm nyob ntau txheej nrog cov pob txha hlau. Ntau lub tsev lag luam tshiab vam khom cov thav duab hlau rau kev ua kom ruaj khov thiab cov phiaj xwm qhib pem teb. Ib qho kev lag luam luv luv hais tias yuav luag 95% ntawm kev tsim kho lag luam tshiab siv cov thav duab hlau. Lub zog ntawm hlau thiab qhov hnyav sib dua ua rau cov kws ua vaj tse hla kev deb nrog tsawg tus ncej. Qhov no tsim cov qauv sab hauv loj qhib thiab cov qauv chaw hloov pauv tau, zoo tagnrho rau cov chaw ua haujlwm, khw muag khoom, thiab cov chaw lag luam.
Cov Zoo ntawm Cov Tsev Hlau
Cov hlau muaj cov txiaj ntsig zoo ntawm cov qauv. Nws qhov sib piv ntawm lub zog thiab qhov hnyav dua li cov pob zeb lossis ntoo. Cov kws ua vaj tse feem ntau xav tau 100–120 kilograms ntawm cov hlau ib square meter rau lub tsev steel-framed. Cov tsev zoo li no tsim tau kwv yees li 480 kilograms CO₂ sib npaug ib square meter hauv cov pa roj carbon uas muaj nyob hauv. Los ntawm qhov sib piv, cov tsev sib npaug ntawm cov pob zeb tsim tau kwv yees li 740.6 kg CO₂e ib square meter. Qhov ntawd sib npaug rau kwv yees li 35% qis dua cov pa roj carbon rau cov qauv steel-framed. Hlau tswj tau ob qho tib si tensile thiab compressive loads. Nws tiv taus kev khoov, shrinkage, thiab creep mus sij hawm ntev. Cov khoom no ua kom muaj kev ruaj khov nyob rau hauv qhov hnyav, kev ntxhov siab ntawm av qeeg, lossis kev txav mus los ntawm cov qauv. Ntau lub tsev steel kav ntev tshaj 50 xyoo nrog kev saib xyuas kom zoo.
Cov Kev Zoo ntawm Kev Tsim Kho Vaj Tse Hlau
Kev ua tiav sai dua yog lwm qhov txiaj ntsig tseem ceeb. Cov neeg ua vaj tse feem ntau ua cov khoom siv hlau ua ntej - cov ntoo, cov kem, cov vaj huam sib luag hauv pem teb thiab phab ntsa - hauv cov chaw teeb tsa uas tswj hwm los ntawm lub Hoobkas. Lawv xa cov modules mus rau qhov chaw npaj rau kev sib dhos sai. Qhov kev ua tiav no tuaj yeem txiav cov sijhawm ua haujlwm tag nrho los ntawm 30-40% piv rau cov txheej txheem ua vaj tse ib txwm muaj. Qee zaum, cov neeg ua vaj tse ua tiav kev tsim kho sai dua 34% piv rau lwm cov kev xaiv ua vaj tse. Lub sijhawm ua tiav sai dua txo cov nqi zog ua haujlwm thiab ua kom cov neeg nyob hauv tsev sai dua. Lawv kuj txo cov khib nyiab hauv qhov chaw thiab txo qhov kev ncua sij hawm ntawm huab cua. Kev ua tiav ua ntej ua rau cov khib nyiab tsim kho me dua li 70% piv rau cov ntoo ua vaj tse.
Cov thav duab hlau kuj txhawb nqa kev tsim qauv tsev uas yoog tau thiab hloov tau. Cov hlau ua vaj tse cia cov kws kes duab vajtse tsim cov chaw loj, tsis muaj kem. Lawv tuaj yeem tsim cov phiaj xwm hauv pem teb qhib thiab yooj yim hloov kho lawv tom qab. Cov neeg tsim kho tuaj yeem nthuav dav ntsug lossis kab rov tav los ntawm kev ntsia hlau rau cov hlau tshiab lossis pem teb. Cov qauv hlau modular ua rau kev kho dua tshiab sai dua thiab rov siv cov qauv uas twb muaj lawm. Vim yog kev ua qauv, kev hloov kho lossis kev nthuav dav feem ntau siv sijhawm tsawg dua li kev hloov kho cov tsev ua los ntawm cov pob zeb.
Cov Tsev Ntsuab Dua Thiab Pheej Yig Dua
Cov tsev ua los ntawm cov hlau kuj sib haum zoo nrog lub hom phiaj ntawm kev ruaj khov thiab kev lag luam ncig. Feem ntau cov hlau ua vaj tse muaj li ntawm 92–93% cov khoom siv rov ua dua tshiab. Tom qab lub tsev raug rhuav tshem, cov hlau ua vaj tse feem ntau rov ua dua tshiab ntawm tus nqi ntawm 98%. Cov kws ua vaj tse tuaj yeem siv cov hlau beams thiab kem hauv kev tsim kho tshiab yam tsis muaj kev poob zog. Qhov ntawd sib txawv ntawm cov pob zeb thiab ntoo, uas feem ntau xaus rau hauv cov khib nyiab pov tseg. Qhov kev rov ua dua tshiab no txo qis qhov cuam tshuam rau ib puag ncig thoob plaws lub neej ntawm lub tsev. Cov pa roj carbon tsawg dua thiab kev rov ua dua tshiab siab ua rau cov hlau ua vaj tse yog qhov kev xaiv zoo tshaj plaws rau kev tsim kho vaj tse ruaj khov thiab "ntsuab".
Qhov Tsis Zoo ntawm Cov Tsev Hlau
Txawm hais tias muaj ntau yam zoo los xij, cov neeg tsim qauv yuav tsum daws cov teeb meem thaum siv cov thav duab hlau. Cov hlau qhia tau tias muaj kev ua haujlwm kub siab. Yog tsis muaj kev rwb thaiv cua sov zoo thiab cov hnab looj tes txuag hluav taws xob, cov tsev yuav poob cua sov yooj yim. Cov pab pawg tsim kho yuav tsum siv cov rwb thaiv cua sov txaus, cov pa dej thaiv, thiab cov cua sov so kom txhim kho kev ua haujlwm hluav taws xob.
Tsis tas li ntawd xwb, cov tsev ua los ntawm cov hlau muaj qhov yuav tsum tau muaj kev paub thiab thev naus laus zis ntau dua ntawm pab pawg tsim kho. Cov hlau yuav kim dua 20-30% dua li cov pob zeb ua vaj tse lossis cib rau cov tsev nyob hauv qee thaj tsam. Cov neeg ua haujlwm txawj rau kev tsim qauv thiab kev tsim kho hlau yuav ua rau muaj kev cuam tshuam ntxiv hauv kev lag luam uas muaj kev paub txog kev tsim kho hlau tsawg.
Thaum kawg, cov neeg tsim qauv yuav tsum ua tib zoo tswj kev tiv thaiv hluav taws thiab kev tiv thaiv xeb kom ruaj khov rau lub neej ntev hauv huab cua tsis zoo lossis siv ntau dhau. Cov khoom siv hlau yooj yim xeb. Yog li ntawd, kev kho cov khoom siv hlau tiv thaiv xeb thiab kev tiv thaiv xeb thaum tsim qauv yog qhov tsim nyog heev.
Qhov Zoo ntawm Chaw Tsim Khoom
Qhov tsis zoo ntawm lub tsev hlau yuav tsum tau cov neeg ua vaj tse xaiv cov khoom siv hlau zoo. Ntawm ib sab tes, cov chaw tsim khoom muaj zog thiab muaj kev paub dhau los tuaj yeem lav qhov zoo ntawm cov xim tiv thaiv xeb thiab cov xim tsuag tiv thaiv xeb, thiab tshuaj xyuas lub neej ua haujlwm ntawm cov khoom. Ntawm qhov tod tes, cov chaw tsim khoom zoo them sai sai rau qhov tseeb ntawm kev ua haujlwm ntawm cov khoom. Nws tuaj yeem txo qhov yuam kev hauv qhov ntev, tuab, thiab qhov chaw ntawm cov qhov mounting ntawm cov khoom, thiab xyuas kom meej tias cov khoom tuaj yeem ntsia ua ke raws li hauv daim duab tsim. Qhov no tsis tsuas yog txuag lub sijhawm xwb, tab sis kuj xyuas kom meej qhov zoo ntawm qhov project.
