Zifukwa ndi njira zodzitetezera zomwe zimapangitsa kuti khola lachitsulo liyandame

Zifukwa zomwe zimapangitsa kuti khola lachitsulo liyandame nthawi zambiri ndi:

(1) Nthawi zoyambira komanso zomaliza zoyika konkriti ndi zazifupi kwambiri, ndipo mikwingwirima ya konkriti m'mabowo ndi yoyambirira kwambiri. Pamene konkire imatsanuliridwa kuchokera ku ngalandeyo ikukwera pansi pa khola lachitsulo, kutsanuliridwa kopitilira kwa konkire kumakweza khola lachitsulo.

(2) Poyeretsa dzenjelo, pamakhala tinthu tambiri ta mchenga tolenjekeka m’matope mkati mwa dzenjelo. Panthawi yothira konkire, tinthu tating'ono ta mchenga timakhazikika pamwamba pa konkire, ndikupanga mchenga wochuluka kwambiri, womwe umakwera pang'onopang'ono ndi pamwamba pa konkire mkati mwa dzenje. Mchengawo ukapitiriza kukwera ndi pansi pa khola lachitsulo, umachirikiza khola lachitsulo.

(3) Mukathira konkire pansi pa khola lachitsulo, kachulukidwe konkire kamakhala kokwera pang'ono ndipo liwiro la kuthira limathamanga kwambiri, zomwe zimapangitsa kuti khola lachitsulo liyandame.

(4) Kutsegula kwa dzenje la khola lachitsulo sikukhazikika bwino.Njira zazikulu zamakono zopewera ndi kusamalira zoyandama zazitsulo zazitsulo zimaphatikizapo.

Njira zazikuluzikulu zaukadaulo zopewera ndikusamalira kuyandama kwa makola achitsulo ndi:

(1) Musanayambe kubowola, ndikofunikira kuyang'ana kaye khoma lamkati la manja apansi. Ngati zomatira zambiri zachuluka, ziyenera kutsukidwa nthawi yomweyo. Ngati zatsimikiziridwa kuti pali deformation, kukonza kuyenera kuchitika nthawi yomweyo. Bowolo likamalizidwa, gwiritsani ntchito chidebe chachikulu chamtundu wa nyundo kuti mukweze mobwerezabwereza ndikutsitsa kangapo kuti muchotse mchenga wotsalira ndi dothi pakhoma lamkati la chitoliro ndikuwonetsetsa kuti pansi pa dzenjelo ndi muyezo.

(2) Mtunda pakati pa kulimbitsa kwa hoop ndi khoma lamkati la casing uyenera kukhala osachepera kawiri kukula kwake kwa coarse aggregate.

(3) Chisamaliro chiyenera kuperekedwa ku ubwino wa kukonza ndi kusonkhanitsa khola lachitsulo kuti zisawonongeke chifukwa cha kugundana panthawi yoyendetsa. Potsitsa khola, kulondola kwa axial kwa khola lachitsulo kuyenera kutsimikiziridwa, ndipo khola lachitsulo siliyenera kuloledwa kugwera momasuka m'chitsime. Pamwamba pa khola lachitsulo sichiyenera kugwedezeka, ndipo samalani kuti musagwirizane ndi khola lachitsulo pamene mukulowetsamo.

(4) Pambuyo pa konkire yotsanuliridwa kutuluka mumsewu pa liwiro lalikulu, imakwera mmwamba pa liwiro linalake. Pamene ngakhale amayendetsa zitsulo khola kuwuka, kuthira konkire ayenera yomweyo inaimitsidwa, ndi kuya kwa ngalande ndi kukwera kwa anatsanulira kale pamwamba konkire ayenera molondola masamu pogwiritsa ntchito kuyeza zida. Pambuyo pokweza ngalandeyo mpaka kutalika kwina, kuthira kumatha kuchitidwanso, ndipo chodabwitsa choyandama chokwera chidzazimiririka.
