Tam sim no, cov hauv paus ntawm photovoltaic kev txhawb nqa hauv av hluav taws xob chaw nres tsheb yog qhov tseem ceeb ntxiv cov vaj tsev cam khwb cia hauv-pawg pawg. Muab cov ntsia hlau txaij txaij lag luam siv tsis tshua muaj. Cov khoos kas hauv qab no yuav qhia qhov no "paub tus neeg tsis paub" rau txhua tus ua photovoltaic Xa mus rau kev xaiv ntawm lub hauv paus bracket.
Ua ntej, hom kauv steel pawg
Cov yeeb nkab kauv steel yog tshwj xeeb cov duab nrog cov qauv duab. Nws muaj lub hauv nruab nrab cov hlau txuas nrog ntau cov kauv. Raws li daim ntawv kho cov hniav, nws feem ntau muab faib ua txheej fawm kib hniav hom kauv hlau pawg thiab txuas ntxiv hniav hniav hom kauv steel piles.
Thib ob, qhov zoo ntawm kauv steel pawg
Ua rau lub sijhawm luv luv ntawm cov kab ke ua kom zoo ntxiv cov pob zeb cam-hauv-situ pawg lub hauv paus rau kev txhawb nqa photovoltaic, kev khawb av, ua kom ib puag ncig kev puas tsuaj, kev tsim kho ntev ntev, qhov chaw siab, thiab kev tshem tawm nyuaj, muab kauv pawg muaj qhov zoo li hauv qab no:
(1) Kev tsim kho yog ceev thiab yig. Muab kauv steel pob zeb feem ntau yog tsim los siv cov tshuab tshwj xeeb. Ib txheej kauv hlau tuaj yeem ua tiav hauv ob peb feeb. Cov pawg pob zeb tuaj yeem siv tau tam sim tom qab kev tsim kho. Tsis muaj teebmeem dabtsi rau kev tsim vaj tse thiab kev saib xyuas, uas txuag cov nyiaj hli ntawm ib tus neeg ua haujlwm ib theem pib. Thiab cov khoom siv kev tsim kho muaj qhov chaw muaj zog, nkag mus ceev thiab tawm tus nqi tsawg, thiab tuaj yeem ncav cuag txhua qhov chaw nyuaj lossis ua haujlwm hauv qhov chaw nqaim.
(2) Kev tswj zoo yooj yim. Muab kauv steel pawg yog txhua yam hauv lub hoobkas, kom tsis txhob muaj qhov tsis zoo ntawm cov txheej txheem yooj yim vim muaj cov txheej txheem sib txawv ntawm cov neeg ua haujlwm tsim thaum lub sijhawm txhim kho cov pob zeb ua kev cuam tshuam-hauv-situ piles.
(3) Ib puag ncig tus phooj ywg thiab rov qab siv dua. Hauv kev tsim cov pob zeb steel, tsis muaj kev txhim kho kev ua haujlwm hauv ntiaj teb, thiab yuav tsum muaj qhov ntsia hlau ncaj qha, thiab yuav luag tsis muaj kev vibration thiab suab nrov, thiab cov kev puas tsuaj ntawm ecological yog qhov qis tshaj. Lub pob zeb pawg hlau yuav tuaj yeem rub tawm rov qab tom qab siv tsis tas yuav tsis muaj kev cuam tshuam dab tsi rau hauv av, thiab lub vev xaib tuaj yeem rov ua dua.
(4) Qhov hloov kho tau ntawm mounting lub photovoltaic module bracket yog siab. Tam sim no, chaw nres tsheb hluav taws xob hauv av yog lub hauv paus roob toj siab, thiab lub tiaj nrog feem ntau tsis sib xws. Txhawm rau kom ntseeg tau tias qhov kev txiav txim siab zoo ntawm cov photovoltaic module, lub voj voos xav kom yooj yim rau nruab thiab kho tau. Vim tias cov kauv kauv steel pawg txuas ncaj qha rau ntawm cov nqaj hlau nrog lub pob zeb, qhov kho tau yooj yim kuj yog cov pob zeb ua ke lub pob zeb ntsia liaj qhov rooj yog qhov loj, txo qhov nyuaj ntawm kev teeb tsa ntawm lub photovoltaic bracket.
Cov teeb meem muaj kauv steel pawg
Cov teeb meem tam sim no ntawm kauv steel pawg yog qhov tsis muaj tus qauv customized, xws li muab kauv steel pawg nqe kev, cov khoom siv steel, lub xyoo lav, thiab kev pabcuam tom qab muag. Muaj tsis muaj qhov yuav tsum tau meej, ua rau cov kev pabcuam tsis zoo. Tsis tas li ntawd, kauv piles muaj qhov sib txawv "algorithms" nyob rau hauv nqe lus ntawm tus nqi txoj kev, cov ntaub ntawv steel, thiab lub xyoo lav, thiab muaj cov sib txawv loj ntawm cov kauv pawg tuam txhab. Qhov tsis muaj cov qauv zoo li no yuav ua rau nws tsis tuaj yeem lav qhov zoo ntawm cov ntawv kauv.
Tsis tas li ntawd, kev tsim lub neej ntawm photovoltaic fais fab chaw nres tsheb yog feem ntau 25 xyoos, thiab seb puas muaj kev tiv thaiv kev xeb ntawm cov kauv steel hlau tuaj yeem lav tau 25 xyoo tsis tau kuaj xyuas. Yog tias nws tsis tuaj yeem lav, yuav muaj teeb meem ntawm cov pawg hloov chaw thaum lub sijhawm ua haujlwm, uas yuav ua rau tus nqi khiav lag luam nce ntxiv.
Plaub, kev sib txuas ntawm cov kauv steel hlau
Muab kauv cov pob zeb steel pob zeb yog feem ntau txuas nrog ntau yam ntawm sab saud los ntawm bolts, flanges, thiab lwm yam, thiab lawv tuaj yeem kho qhov siab ntawm kem yooj ywm. Lub flange ntawm cov kauv steel pawg yog ua los ntawm cov ntawv steel ntawm qee qhov tuab thiab welded nrog nruab nrab steel ncej tag nrho. Cov ntsia liaj qhov rooj thaiv tau tseg rau ntawm qhov txuas txuas rau kom yooj yim txuas nrog lub taub hluav taws xob ntawm lub tshuab thaum nruab teeb tsa thiab txuas nrog kev txhawb nqa sab saud. Qee cov pawg tsis tuaj yeem flanged, tab sis cov ntsia liaj qhov rooj raug txwv nyob rau sab qaum, thiab cov ntsia hlau txuas nrog lub hwj chim los ntawm cov ntsia liaj qhov rooj thaum lub sijhawm teeb tsa, thiab tseem tuaj yeem siv txuas nrog kev txhawb nqa sab saud tom qab kev teeb tsa.
V. Cov qauv kev ntseeg tau ntawm cov kauv steel hlau
Cov qauv ntawm qhov qauv ntseeg tau hais txog kev nyab xeeb, kev siv tau, thiab ua ntev ntawm tus qauv. Cov neeg kho hauv qab no yuav qhia txog kev teeb tsa kev ntseeg tau ntawm kauv steel piles los ntawm peb yam.
(1) Kev nyab xeeb ntawm kauv steel pawg
Kev Nyab Xeeb tsuas yog hais txog tus kabmob muaj peev xwm ntawm muab kauv hlau pawg, uas muaj kev nyab xeeb tsis muaj kev puas tsuaj.
Raws li cov ntawv nyeem uas cuam tshuam, qhov hloov ntawm cov hniav txhaws piv (hniav suab / hniav taub) ntawm cov kauv steel pawg yog qhov tseem ceeb cuam tshuam rau qhov kawg rub tawm thiab compressive bearing muaj peev xwm ntawm steel pawg. Raws li kev tshawb nrhiav kev tshawb nrhiav, qhov kawg muaj peev xwm ntawm cov pawg yog qhov zoo tshaj plaws thaum cov hniav sib nrug piv S / D = 3 ~ 4. Rau cov kauv me me steel piles feem ntau siv nyob rau hauv photovoltaic lub hauv paus, lub suab sib txuas ntawm S / D = 3 yog qhov pom zoo. Kev rub tawm thiab cov kabmob muaj peev xwm ntawm ob-blade pawg nce nrog qhov nce ntawm cov hniav (lub ntsej muag (square hniav square), thiab muaj kwv yees kab sib luag. Los ntawm qhov pom ntawm kev coj tus kheej muaj peev xwm, ob chav blade pawg zoo dua li cov hniav txuas mus tas li thiab muaj qee yam zoo hauv kev tsim kho. Qhov tsim kom muaj qhov tsim tshwj xeeb ntawm cov tib pawg cov kabmob muaj peev xwm ntawm cov kauv ntawm cov kauv yog ≤10KN, thiab tus nqi tsim kho lub zog yog ≤20KN, uas ua tau raws li cov qauv tsim. Qhov "Tsim Kev Qhia Tshwj Xeeb rau Kev Siv Hluav Taws Xob Photovoltaic" kuj tseem hais txog lub pob zeb tawg, tab sis tsuas yog qhia meej txha hniav tuab thiab qhov dav: cov yeeb nkab steel phab ntsa tuab ntawm cov kauv pawg yuav tsum tsis pub tsawg dua 4 hli, thiab cov hniav txuas ntxiv dav (taub) loj dua lub tom kawg. Ntawm 20mm, tus hniav tuab yuav tsum ntau dua 5 hli, thiab thaum tus hniav dav tsawg dua 20mm, tus hniav txha hniav yuav tsum tsis pub tsawg dua 2 hli, thiab qhov sib npaug ntawm qhov dav rau tuab yuav tsum tsis pub ntau tshaj 30. Qhov ntev ntawm muab kauv steel pawg yog zoo ib yam li qhov ntev ntawm kev txhawb nqa cov pob zeb thaiv-hauv-pawg pawg, uas feem ntau kwv yees li 2m.
(2) Kev siv tau ntawm kauv steel piles
Kev siv feem ntau yog hais txog cov teeb meem ntawm deformation thiab tawg ntawm cov kauv steel pawg.
Vim tias lub zog ntawm cov kauv steel pawg nws tus kheej yog qhov siab, lub photovoltaic bracket system tsis muaj qhov hnyav tshwj xeeb rau ntawm kauv steel pawg, thiab cov kauv steel pawg feem ntau tsis muaj deformation thiab tawg ntau dhau.
(3) Lub caij nyoog ruaj ntawm muab kauv steel pawg
Kev ua haujlwm ntev yog hais txog kev tiv thaiv kev xeb ntawm kauv steel piles, uas yog qhov teeb meem tseem ceeb rau kev muab kauv steel hlau.
Nyob rau tam sim no, anticorrosion ntawm hlau txuas hauv photovoltaic fais fab chaw nres tsheb feem ntau siv cov kev ntsuas kub kub galvanized anticorrosive. Raws li "Kev Tsim Qauv Cov Lus Qhia rau Photovoltaic Fais Fab Lub Zog", thaum kub-dip galvanized anticorrosive kev kho mob tau saws rau cov kauv piles, cov ntawv galvanized yuav tsum tau ua raws li lub teb chaws tam sim no tus qauv "Cov Kev Xav Tau thiab Kev Ntsuas Ua Rau Kub-dip Galvanized Coatings ntawm Hlau Cov Qhov Chaw Uas Them Los Hlau "Raws li cov kev cai, qhov tsawg kawg galvanized tuab yuav tsum ua tau raws li cov hauv qab no:
Txawm hais tias muaj lwm cov qauv, kev ua haujlwm ntawm kev sib kis ntawm cov kauv steel pawg yuav tsum ua tau raws li 25-xyoo kev tsim kev pabcuam lub neej nyob ntawm photovoltaic fais fab nroj tsuag, thiab nws yuav siv sijhawm los sim.
Kev thov ntau ntawm muab kauv steel pawg
Raws li cov lus qhia saum toj no, "Kev Tsim Qauv Kev Tshawb Fawb rau Photovoltaic Fais Fab Lub Zog" tseem muab cov kev pom zoo ntawm cov kauv pawg: thaum cov dej hauv av ntawm qhov chaw tsawg, qhov tob ntawm ruaj khov tuav txheej yog loj, kev tsim kho nyob rau lub caij ntuj no, struts yog undulating lossis qhov chaw yuav tsum muaj qhov rov qab siab dua, hauv qhov no, lub hauv paus ntawm kev txhawb nqa tuaj yeem yog cov kauv sib xyaw.
