Bowo la nangula pambuyo pa kukonzanso kumatanthauza kuti dzenje lowongoka litabowoleredwa mu gawo lapansi la konkriti, dzenjelo limasinthidwanso pansi pa dzenjelo, ndipo pabowolo litatha kubwezeretsanso ndipo gawo lotseguka la bawuti la nangula limapanga njira yolumikizirana. dziwani kugwirizana kwa post-anchore.
Bawuti yakumbuyo yamakina opangira nangula imapangidwa ndi screw, bellow casing, washer lathyathyathya, makina ochapira masika, nati, ndipo amapangidwa ndi chitsulo chosapanga dzimbiri 5.8, 8.8 giredi chitsulo, 304 (A2-70)/316 (A4-80) chitsulo chosapanga dzimbiri ndi zipangizo zina. Kuchiza pamwamba ndi electrogalvanizing (avareji ya zinki wosanjikiza makulidwe ＞ 5 μ m) , yogwiritsidwa ntchito kumalo wamba; Hot dip galvanizing (avareji nthaka wosanjikiza makulidwe> 45 μ m) , ntchito m'malo dzimbiri.
Kumbuyo kwa belled mechanical nangula bolt idzagwiritsidwa ntchito pazinthu zapansi monga konkire yosasweka / konkire yosweka, miyala yachilengedwe, ndi zina zotero, kukonza zigawo zomanga ndi katundu wambiri kapena kukhazikitsa zipangizo zolemera. Bawuti ya nangula yakumbuyo yakumbuyo imakhala yokhazikika komanso yabwino kwambiri yoyimitsa pansi pa katundu wambiri, kugwedezeka kwamphamvu komanso kuchuluka kwamphamvu. Pambuyo potseka makina ndi kukhazikitsa, palibe chifukwa chodikirira nthawi yochiritsa kuti ntchito yomanga ikhale yabwino.
The ndondomeko mawotchi nangula bawuti kumbuyo kukula pansi ndi motere: choyamba, ntchito molunjika dzenje kubowola kubowola mabowo ndi kuya kwa diameters lolingana, ndiye ntchito wapadera pansi kutambasula kubowola kugwedeza pansi kukulitsa pansi mu mphero- mabowo obowoka, kenako gwiritsani ntchito chowuzirira mwaye kuti muyanjanitse dzenjelo mpaka fumbi litasefukira mu dzenjelo, ndipo pomaliza pake mugunde kumbuyo kwa bawuti ya nangula yakumbuyo kuti mukulitse pansi kuti mumalize kuzika.
