Ua ntej koj pib nchuav lub hauv paus thiab txawm tias tsim lub tsev, koj yuav tsum ua cov haujlwm tshawb nrhiav. Lawv yuav tso cai rau koj kom pom cov cim tseem ceeb xws li av noo ntawm qhov chaw, theem ntawm cov dej hauv av, qhov tob ntawm cov av khov thaum lub caij txias, nrog rau kev txiav txim siab lwm yam uas tso cai rau koj xaiv qhov zoo ntawm lub hauv paus. rau lub tsev. Lub hauv paus tseem yog poured nyob rau hauv lub tsev tsuas yog tom qab kev xam tau hais txog lub neej yav tom ntej load rau nws. Ob hom kev ua haujlwm no tau tso siab rau cov kws tshaj lij.
Feem ntau, cov hauv paus sawb yog siv rau cov tsev ntiag tug. Siv cov piv txwv ntawm hom kev tsim kho no, peb yuav xav txog cov hauv paus ntsiab lus ntawm txoj haujlwm no. Koj tseem yuav tau suav (tsawg kawg yog kwv yees li) nws yuav raug nqi npaum li cas los sau lub hauv paus. Tus nqi nyob ntawm, ua ntej ntawm tag nrho cov, ntawm qhov loj ntawm lub tsev yav tom ntej. Hom av thiab cov khoom siv los ntawm cov phab ntsa yuav ua tau kuj tseem ceeb heev hauv qhov no. Piv txwv li, nyob rau hauv pob zeb hauv av, nws tsis yog yuav tsum tau kom tob lub hauv paus ntau dhau, thiab yog li ntawd, nws cov nqi kawg yuav qis dua. Ib yamtib yam mus rau lub teeb phab ntsa, piv txwv li, ncej sawv daws yuav.
Kev ua lub hauv paus rau lub tsev pib nrog kev ua haujlwm thiab khawb lub hauv paus. Tom qab lub tom kawg yog npaj txhij, formwork yog ntsia rau hauv nws. Thaum tsim cov tsev me me, koj tuaj yeem siv cov khoom siv ruaj khov ntawm tes rau nws cov khoom siv. Tab sis feem ntau cov formwork yog assembled los ntawm ntoo panels. Ua li no, tshwj xeeb kev txhawb nqa racks raug ntsia rau hauv lub qhov. Tom qab mounting cov ntaub thaiv npog, lawv tau kho ntxiv nrog spacers.
Nyob rau hauv rooj plaub no, koj yuav tsum xyuas kom meej tias qhov kev ncua deb ntawm cov ntaub thaiv npog nyob ib ncig ntawm tag nrho cov perimeter yog tib yam. Ua ntej kev teeb tsa, kab rov tav ntawm lub qhov hauv qab kuj raug kuaj xyuas.
Tom qab kev teeb tsa, cov xuab zeb yog nchuav rau hauv qab ntawm lub qhov nrog ib txheej ntawm 15 cm. Tom ntej no, kev txhawb nqa yog txuas nrog lub formwork. Hauv kev tsim cov qauv hlau no, nws tsis pom zoo kom siv vuam, vim qhov sib txuas ntawm cov pas nrig hauv qhov no tuaj yeem pib xeb sai. Nws yog qhov zoo tshaj plaws los siv ib txoj hlua khi tshwj xeeb. Cov kauj ruam tom ntej yuav tsum yog qhov tseeb nchuav ntawm lub hauv paus rau lub tsev.
Ua li no, koj yuav xav tau cov cement, crushed pob zeb (uas tuaj yeem hloov tau cov pob zeb), dej thiab cov cuab yeej tshwj xeeb. Tau kawg, koj tuaj yeem siv cov txheej txheem qub (trough thiab hoe) thaum sib xyaw ua vaj tse, tab sis nws yog qhov zoo tshaj los yuav lub pob zeb niaj hnub no.
Nrog nwssiv cov cuab yeej ntawm pouring lub hauv paus yuav yooj yim li sai tau. Thiab cov pob zeb sib tov nws tus kheej yuav tig tawm kom zoo dua. Muab nws tso rau hauv lub formwork hauv txheej. Yog tias koj txiav txim siab siv lub pob zeb rubble, thawj 15 cm ntawm pob zeb tau muab tso rau ntawm cov xuab zeb, ces pob zeb tau muab tso rau ntawm nws. Tom qab ntawd ntxiv pob zeb, ces pob zeb, thiab lwm yam.
Nws yog ib qho tsim nyog los xyuas kom meej tias qhov kev ncua deb ntawm cov cobblestones thiab formwork yog tsawg kawg yog 5 cm. Ua li no, siv cov qib tsev. Ntawm no, xws li ib tug txheej txheem xws li pouring lub hauv paus rau ib lub tsev yuav suav hais tias tiav. Qhob hardens thaum nruab hnub nyob rau hauv ib tug sov lub sij hawm ntawm lub sij hawm. Tom qab lub sijhawm no, nws yuav muaj peev xwm tshem tawm cov formwork. Rau ob lub lis piam tom ntej no, yog tias huab cua sab nraud qhuav, lub hauv paus yuav tsum tau moistened nrog dej ib ntus kom tsis txhob tawg.
Qhob thaum kawg hardens nyob rau hauv ib hlis. Tsuas yog tom qab tos lub sijhawm no, koj tuaj yeem pib ua haujlwm tsis muaj dej thiab tsim cov phab ntsa.
