Kodi nangula wa chiyani?
Anangula woponya, yomwe imadziwikanso kuti makina opangira nangula kapena nangula wa konkire, ndi mtundu wa chomangira chomwe chimagwiritsidwa ntchito popanga malo otetezeka mu konkriti, masonry, kapena zipangizo zina zolimba zomwe mungathe kuziyikapo, monga ma handrails, mabokosi amagetsi, kapena makina. Ndizothandiza makamaka mukafuna kugwiritsitsa mwamphamvu, kokhazikika.
Kulemera kapena katundu amene nangula wogwetsa angagwire zimadalira zinthu zingapo, kuphatikizapo kukula kwa nangula, ubwino ndi chikhalidwe cha zinthu zoyambira (konkire, zomangamanga, ndi zina zotero), kuya kwa dzenje, ndi mtundu wa katundu womwe umagwiritsidwa ntchito (kuthamanga, kukameta ubweya, kapena kuphatikiza).
Kukhazikitsa nthawi zambiri kumakhala ndi izi:
1. Kubowola Bowo ndi Kuyeretsa: Bowo limabowoleredwa mu konkire kapena mwala pogwiritsa ntchito kabowo kakang'ono kamene kamafanana ndi m'mimba mwake ndi kuya kotchulidwa kwa nangula. Chotsani fumbi ndi zinyalala kukonzekera unsembe.
2. Kulowetsa Nangula: Nangula wogwetsa, yemwe amakhala ndi chigoba cha cylindrical chokhala ndi ulusi wamkati ndi wedge wokulirakulira, amalowetsedwa mu dzenje lobowola.
3. Kukhazikitsa Nangula: Chida chokhazikitsira kapena bolt chomwe chimafanana ndi ulusi wamkati wa nangula chimagwiritsidwa ntchito kukoka mphero yomwe ikukulirakulira mu chipolopolo, ndikupangitsa kuti ipunduke ndikukulitsa kunja. Kukula kumeneku kumakanikizira chigobacho molimba m'mbali mwa dzenje, ndikupanga cholimba komanso chotetezeka.
4. Kuyang'ana: Pambuyo pa kukhazikitsa, onetsetsani kuti anangula akhazikika bwino ndipo sanasulidwe. Ngati n'kotheka, kuyesa kotulutsa kungathe kuchitidwa kuti atsimikizire mphamvu yonyamula katundu wa nangula.
Nangula wogwetsaamasankhidwa chifukwa cha kuthekera kwawo kupereka mphamvu yonyamula katundu wambiri komanso ntchito zomwe chomangiracho chimafunikira kuthamangitsidwa kapena kutsika pang'ono pamwamba pa zinthuzo. Amagwiritsidwa ntchito kwambiri pomanga, kupanga, ndi makonzedwe osiyanasiyana a mafakitale komwe kumafunika kulimba kwambiri.
Zikomo powerenga, ngati mukufuna kuwona zambiri zomwe timapereka mutha kutsatira maulalo pansipa!
