Txhua tus neeg nrhiav kev tiv thaiv lawv lub tsev thiab thaj av ntawm qhov muag tsis pom, tsiaj nyaum thiab cov qhua tsis tau caw. Yog vim li ntawd ntau lub laj kab. Ntawm chav kawm, lub laj kab yuav tsum tsis tsuas yog tiv thaiv, tab sis kuj muaj ib tug txaus nyiam tsos, yuav txhim khu kev qha thiab muaj zog txaus. Nyob rau tib lub sijhawm, xws li laj kab yuav tsum tau ua ke nrog kev lag luam ntawm nws txoj kev tsim kho. Yuav xaiv dab tsi? Nyob rau hauv rooj plaub no, ib lub laj kab ntawm cov ntsia hlau pawg yog zoo meej. Kev tshuaj xyuas ntawm cov qauv zoo li no feem ntau yog qhov zoo. Tom qab tag nrho, xws li laj kab muaj ntau qhov zoo thiab qhov tsis zoo me me.
Screw piles on the laj kab
Cov qauv zoo li no, raws li lub npe qhia, yog mounted siv cov ntsia hlau pawg. Lawv yog cov hauv paus rau cov laj kab ncej. Tsis tas li ntawd, ntsia hlau pawg tuaj yeem ua tsis tau tsuas yog lub hauv paus, tab sis kuj yog tus ncej ntawm tag nrho cov qauv. Xws li cov khoom yog hollow hlau kav. Ib qho kawg ntawm cov khoom muaj cov xov tshwj xeeb thiab cov lus ntse.
Nws tsim nyog sau cia tias cov ntsia hlau pawg ntawm lub laj kab yog tiv thaiv los ntawm corrosion. Hauv lub Hoobkas, lawv tau coated nrog txheej tshwj xeeb.
Yuav siv li cas rau laj kab
Zoocov khoom tuaj yeem paub qhov txawv raws li ntau qhov kev txwv. Ua ntej tshaj plaws, pawg muab faib los ntawm hom xov:
- Standard.
- Nrog cov hniav.
- nrog xov tooj.
Cov ntsia hlau loj ntawm lub laj kab nrog cov xov sib txawv tsis tsuas yog nyob rau hauv tsos, tab sis kuj nyob rau hauv cov loads uas lawv tuaj yeem tiv taus. Qhov muaj zog tshaj plaws - nrog cov hniav. Txawm li cas los xij, cov khoom no kim heev. Raws li txoj cai, cov pawg no tsuas muaj ob lub ntsej muag xwb. Qhov no tso cai rau koj los ua kom muaj kev ntseeg siab ntawm kev txhawb nqa zoo li no, nrog rau kev faib tawm lub siab uas tau ua rau nws. Raws li qhov tshwm sim, cov kabmob muaj peev xwm ntawm cov khoom tau raug txhim kho zoo. Tsis tas li ntawd, nws tuaj yeem siv cov pawg no ntawm yuav luag txhua hom av.
Kuj cov khoom lag luam txawv ntawm txoj kab. Txhawm rau txhim kho lub laj kab, pawg feem ntau yog siv, uas qhov ntsuas no yog 57, 76 thiab 89 millimeters. Txawm li cas los xij, cov khoom siv hlau los ntawm cov kav dej tseem yog qhov nrov tshaj plaws. Lawv txoj kab uas hla yog 76 millimeters.
Ntxiv rau, pawg yog qhov txawv los ntawm txoj kev ntawm lawv cov khoom siv: cam khwb cia, ua ke thiab welded. Cov yav tas yog tsuas yog siv rau kev tsim kho ntawm laj kab. Cov qauv cam khwb cia yog qhov zoo tshaj plaws rau kev tsim vaj tsev, vim lawv muaj peev xwm tiv taus cov khoom loj. Cov khoom sib xyaw ua ke yog siv tsawg dua, vim tias lawv tsis zoo rau yav dhau los ntawm cov yam ntxwv.
Npaj rau kev teeb tsa
Txhim kho lub laj kab ntawm cov ntsia hlau, zoo li txhua yam kev tsim kho, muaj qee qhov nuances,uas yuav tsum tau coj mus rau hauv tus account. Ua ntej pib lub installation, nws yog ib qho tsim nyog yuav tsum tau ua ib qho kev xeem screwing. Qhov no yuav txiav txim siab txog qib kev nkag mus ntawm cov qauv. Nws yuav tsum raug sau tseg tias qhov ntsuas no ncaj qha nyob ntawm qhov muaj pes tsawg leeg ntawm cov av. Yog hais tias cov av hnyav heev, cov pawg tuaj yeem thauj tau tsuas yog 1.5 meters, txij li thaum screwing nyob rau hauv xws li tej yam kev mob yuav tsis yooj yim sua. Tom qab ntawd koj yuav tsum kos lub perimeter. Nyob rau tib lub sijhawm, nws tsim nyog nco ntsoov txog cov khoom siv hauv av.
Kev txhim kho pawg
Qhov kev ncua deb ntawm kev txhawb nqa yuav tsum yog los ntawm ob mus rau peb meters. Nws tag nrho yog nyob ntawm qhov xwm txheej ntawm cov av. Ib kauj ruam ntawm ob thiab ib nrab metres yog suav tias yog qhov zoo tshaj plaws. Tom qab lub markup tiav, koj tuaj yeem mus rau lub installation ntawm pawg. Ua ntej koj yuav tsum ua kom muaj kev ntxhov siab hauv av li ntawm 20 centimeters. Nws yog nyob rau hauv cov chaw uas screwing yuav tshwm sim.
Qhov no tuaj yeem ua tau manually nrog lub zog ua los ntawm cov yeeb nkab hlau. Nyob rau tib lub sijhawm, nws qhov ntev ntawm ob sab yuav tsum yog tsawg kawg yog ob meters. Thaum screwing nyob rau hauv, nws yog ib qho tsim nyog los xyuas kom meej tias cov pawg nkag mus rau hauv av sib npaug thiab sib npaug. Txhawm rau ua qhov no, koj tuaj yeem siv cov qib lossis cov kav dej. Yuav kho qhov tsis sib xws yav tom ntej.
Yuav ua li cas tom qab txhim kho pawg
Tom qab tag nrho cov pawg tau teeb tsa, lawv yuav tsum tau txiav mus rau theem uas xav tau, thiab tom qab ntawd ntim cov pob zeb ua pob zeb. Txhawm rau ua qhov no, nws yog qhov zoo dua los siv hom cement tsis qis dua M-150. Qhov no yuav ua rau kom muaj peev xwm ua kom muaj peev xwm ntawm tag nrho cov qauv, nrog rau kev tiv thaiv kev ya raws thiab nwsnkag mus rau hauv cov khoom.
Txhawm rau tiv thaiv sab saum toj ntawm pawg, koj yuav tsum tau muab lawv nrog ob lub ntsiab lus tshwj xeeb. Tsis tas li ntawd, nws tsim nyog kho cov qauv nrog hnav-tiv thaiv corrosion mastic.
Yog tias tsim nyog, kev nyuaj siab me me tuaj yeem ua nyob ib puag ncig cov pawg thiab ntim cov cement mortar.
Next step
Cov kauj ruam hauv qab no nyob ntawm seb koj xav tau ntau npaum li cas:
- Yog tias qhov siab ntawm cov qauv yog los ntawm 1.5 mus rau 2 meters, ces nws yog ib qho tsim nyog yuav tsum tau teeb tsa cov lus qhia. Qhov no yog qhov tsim nyog kom ruaj ntseg cov khoom zoo dua.
- Yog qhov siab yog los ntawm 30 mus rau 60 centimeters, ces qhov kev teeb tsa ntawm lub laj kab ncej yog tsim nyog.
Txhob laj kab
Thaum cov ntsia hlau pawg tau teeb tsa ntawm lub laj kab, koj tuaj yeem txuas ntxiv nrog kev teeb tsa ntawm lub laj kab. Feem ntau, rau cov laj thawj no, koj tuaj yeem siv ntoo, mesh lossis corrugated board. Lub laj kab ua los ntawm cov khoom siv zoo li zoo nkauj thiab ua tau raws li yuav luag txhua qhov kev xav tau. Feem ntau siv corrugated board. Cov panels nyob rau hauv cov ntaub ntawv no feem ntau yog ntsia thaum uas tig mus rau cov ncej txhawb. Thaum txuas thawj daim ntawv, nws yog ib qho tseem ceeb kom ua tau txhua yam kev ntsuas kom raug. Txwv tsis pub, kev cuam tshuam yuav tshwm sim thaum ua haujlwm ntxiv.
Tsis tas li ntawd, thaum txhim kho lub vaj huam sib luag thawj zaug, xyuas kom meej tias cov ntug qis tseem nyob saum av ntawm qhov siab tsawg kawg yog 5 centimeters. Txwv tsis pub, cov khoom yuav tsis kav ntev thaum raug dej.
Cov theem tseem ceeb ntawm kev tsim khohedges
Ib lub laj kab ntoo ntawm cov ntsia hlau los yog lub laj kab corrugated zoo li qub thiab zoo. Txawm li cas los xij, txhawm rau ua tiav cov txiaj ntsig xav tau, nws tsim nyog ua raws li hauv qab no:
- Txiav txim siab qhov siab ntawm tus ciam teb hauv qab ntawm daim ntawv profiled lossis board los ntawm hauv av.
- Nthuav cov xov kev tsim kho ntawm cov ncej ntawm qhov siab. Qhov no yuav ua rau installation yooj yim dua.
- Txuas lub vaj huam sib luag thawj zaug, coj los ntawm cov xov stretched.
- Kho cov khoom siv hedge.
- Txhim daim ntawv thib ob.
Tseem. Kev txhim kho lub laj kab ntawm cov ntsia hlau pawg yog ib txoj kev ntev uas yuav tsum tau ua raws li txhua txoj cai.
