Kev xaiv ntau yam ntawm cov hauv paus, ua raws li cov txheej txheem sib txawv, tso cai rau koj xaiv cov kev xaiv uas haum tshaj plaws tsis yog rau cov av xwb, tab sis kuj raws li kev tsim ntawm lub tsev.
Rau lub caij ntuj sov tsim tsev, siv ib lub sawb lossis kem lub hauv paus ntau dua. Tab sis tsis muaj tsawg nthuav yog qhov kev xaiv ntawm kev siv pawg, tshwj xeeb tshaj yog tias lub xaib muaj txoj kab nqes. Thaum lub tsev nyob rau hauv ib lub nroog uas muaj ib tug heev tuab lub tsev, lub hauv paus ntawm ib tug dhuav foundation yog qhov zoo tshaj plaws kev daws teeb meem. Lub tshuab ntawm nws cov chaw tsim khoom tso cai rau koj tsim lub tsev yam tsis muaj teeb meem rau cov tsev nyob ze. Lub tswv yim tseem ceeb ntawm txoj kev no yog cov pawg tsis nkag mus tob rau hauv av, tab sis "loj" tawm hauv av (vim yog txhaws).
Lub hauv paus ntawm kev dhuav tuaj yeem ua tau ntau txoj hauv kev. Tau khawb los yog drilled lub qhov dej, ib lub yeeb nkab yog ntsia rau hauv nws (los yog ib tug tshem tau formwork yog ua). Raws li lub qhov puv, tag nrho cov ntsiab lus tsis tsim nyog tuaj yeem raug tshem tawm, tab sis qee zaum lawv raug tso tseg kom muab lub zog ntxiv rau cov qauv. Txhawm rau kom zoo dua ntawm cov pob zeb, ib qho kev xyaum tshwj xeeb yog siv, uas tsim kev co (thiab cov muaj pes tsawg leeg nyob nruj dua).
Pibsau lub hauv paus ntawm kev dhuav nrog kev tsim ntawm lub hauv ncoo. Nws tuaj yeem ua los ntawm cov pob zeb crushed, xuab zeb lossis pob zeb sib xyaw, ua ntej tamped lawv. Tom qab ntawd los ntawm kev txhaws ntawm qhov dej nrog cov khoom tseem ceeb. Nws tuaj yeem yog ob peb txheej ntawm pob zeb lossis pob zeb ua ke nrog pob zeb. Cobblestone, sandstone los yog limestone yog haum ntawm no, tsuav yog nws tseem thiab ruaj khov. Txwv tsis pub, nws yog hu ua pob zeb rubble. Txhawm rau ua kom lub zog ntawm pawg dhuav, kev siv dag zog tuaj yeem siv tau, uas yuav tsum tau txuas mus rau hauv ib qho qauv siv cov grillage.
Qhov dav ntawm lub hauv paus, ua los ntawm cov dhuav pawg, nyob ntawm, ua ntej ntawm tag nrho cov, ntawm lub thickness ntawm phab ntsa ntawm lub tsev. Cov tsev thav duab tsis xav tau qhov loj me, vim cov phab ntsa yog lub teeb thiab tsis tuab heev. Qhov dav ntawm lub hauv paus hauv qhov kev xaiv no tuaj yeem sib haum rau qhov ntev ntawm phab ntsa. Rau lub tsev ua los ntawm ntoo, lub hauv paus yuav tsum yog 20-40 mm loj dua thiaj li yuav faib cov load ntau tusyees. Yog li ntawd, nws yog cov khoom siv los ntawm kev tsim lub tsev uas txiav txim siab qhov dav ntawm txhua lub hauv paus, tshwj tsis yog cov slab. Nyob ntawd, lub qhov cub yog nchuav raws li qhov loj ntawm lub tsev.
Nws yog ib qho tsim nyog yuav tsum tau xyuam xim rau qhov zoo ntawm cov khoom siv thaum tsim lub tsev. Cement rau lub hauv paus yuav tsum tau xaiv raws li cov yam ntxwv ntawm lub zog. Cov ntsuas no tau cuam tshuam los ntawm ntau yam impurities uas txhim kho qhov zoo ntawm cov khoom tshwm sim. Tab sis yog tias qhov no cuam tshuam rau kev tsim tsev, ces koj tuaj yeem nqa cov cement qis dua rau lub chaw nres tsheb (thiab, ntxiv rau, lub tsev txhab nyiaj).
Nws yog qhov zoo dua los sau lub hauv paus ntawm kev dhuavceev-hardening cement, tab sis dilute nws nyob rau hauv me me. Npaj txhua qhov ntxiv tom ntej tom qab txheej dhau los tau raug rammed. Thaum muas cov cement, nco ntsoov tias nws tsis yog ib txwm ua tau kom raug tswj cov proportions ntawm tag nrho cov khoom tuaj. Nyob rau tib lub sijhawm, cov xuab zeb kuj yuav tsum muaj qhov sib xws thiab zoo.
Los ntawm muab tag nrho cov khoom sib xyaw ua ke, koj tuaj yeem tau txais lub hauv paus ruaj khov, thiab yog li ntawd, kev ntseeg siab tias lub tsev yuav sawv mus ntev.
