Kukula kwa ntchito
Amagwiritsidwa ntchito m'mafakitale ochitira zinthu monga malo osungiramo katundu, m'masitolo akuluakulu, m'mafakitale akuluakulu ogwiritsira ntchito makina, m'malo oimika magalimoto, m'malo osungira katundu, m'mabwalo ndi m'zipinda zina.
Makhalidwe a magwiridwe antchito
Imafalikira mofanana pamwamba pa konkire poyamba pamene imalimba, ndipo ikauma bwino, imapanga gawo lonse lolimba komanso lolimba kwambiri ndi nthaka ya konkire, yomwe ndi yolimba, yolimba, yolimba, komanso yolimba kwambiri ngati nthaka yolimba kwambiri. Itha kupangidwa pamodzi ndi pansi pa konkire, kuchepetsa nthawi yogwirira ntchito, komanso palibe chifukwa chopangira gawo lolinganiza matope.
Makhalidwe a dongosolo
Kapangidwe kosavuta, kofalikira mwachindunji pa konkire yatsopano, kusunga nthawi ndi ntchito, palibe chifukwa chopangira matope olinganiza; kukana kukanda kwambiri, kuchepetsa fumbi, kukana kugwedezeka, kukana mafuta ndi mafuta.
Njira yomanga
◇ Kukonza pamwamba pa konkriti: gwiritsani ntchito trowel yamakina yokhala ndi diski kuti muchotse mofanana slurry yoyandama pamwamba pa konkriti;
◇Zinthu zofalitsira: falitsani 2/3 ya mlingo womwe waperekedwa wa zinthu zolimba zomwe sizingawonongeke mofanana pamwamba pa konkriti poyamba, kenako muzimupukuta ndi makina osalala otsika liwiro;
◇Kukwecha zinthu zomangira: kukanda ndi kukweza zinthu zolimba zomwe sizimawonongeka bwino motsatira njira zopingasa ndi zotalika pogwiritsa ntchito chokwecha cha mamita 6;
◇Kufalitsa zinthu zingapo: kufalitsa mofanana 1/3 ya mlingo womwe waperekedwa wa zinthu zolimba zomwe sizingawonongeke (pamwamba pa zinthu zomwe sizingawonongeke zomwe zapukutidwa nthawi zambiri), ndikupukutanso pamwamba pake ndi makina osalala;
◇ Kupukuta pamwamba: malinga ndi kuuma kwa konkriti, sinthani ngodya ya tsamba pa makina opukuta, ndikupukuta pamwamba kuti muwonetsetse kuti pamwamba pake pali posalala komanso pathyathyathya;
◇ Kukonza ndi kukulitsa maziko a pansi: pansi wolimba wosawonongeka uyenera kusungidwa pamwamba pa maola 4 mpaka 6 ntchito yomanga itatha, kuti madzi asatuluke mofulumira pamwamba, ndikuwonetsetsa kuti mphamvu ya zinthu zosawonongeka ikukula bwino.
