Mitundu ya mabawuti a nangula
Maboti a nangula amatha kugawidwa m'maboliti okhazikika, ma bolt osunthika, mabawuti owonjezera a nangula ndi ma bolt omangika.
1. Mtsuko wa nangula wokhazikika, womwe umatchedwanso anchor bolt wamfupi, umatsanuliridwa pamodzi ndi maziko kuti akonze zida popanda kugwedezeka kwamphamvu ndi kukhudzidwa.
2. Boti ya nangula yosunthika, yomwe imadziwikanso kuti nangula wautali, ndi cholumikizira cha nangula, chomwe chimagwiritsidwa ntchito kukonza makina olemera ndi zida zokhala ndi kugwedezeka kwamphamvu komanso kukhudzidwa pogwira ntchito.
3. Maboti okulitsa malo osungiramo nangula nthawi zambiri amagwiritsidwa ntchito kukonza zida zosavuta kapena zida zothandizira kuyimirira.Kuyika kwa wononga phazi la anchor kudzakwaniritsa izi:
(1) Mtunda wochokera pakati pa bawuti mpaka m'mphepete mwa mazikowo suyenera kuchepera nthawi 7 m'mimba mwake mwa bawuti pamalo okulirapo;
(2) Kulimba kwa maziko a zomangira phazi zomwe zayikidwa mu nangula wowonjezedwa sizikhala zosachepera 10MPa;
(3) Sipadzakhala ming'alu pa bowo la kubowola, ndipo chisamaliro chiyenera kuperekedwa kuti zisagwirizane ndi zitsulo zazitsulo ndi mapaipi okwirira mu maziko.
4. Zomangira za nangula zimagwiritsidwa ntchito kwambiri m'zaka zaposachedwapa, ndipo njira zawo ndi zofunikira ndizofanana ndi zowonjezera zowonjezera.Koma pamene kugwirizana, tcherani khutu kuwomba kunja sundries mu dzenje, ndipo musakhudzidwe ndi yonyowa pokonza.
Tsatanetsatane wa ma bolt a nangula
Choyamba, Gulu la mabawuti a nangula Maboliti a nangula amatha kugawidwa m'mabawuti okhazikika, mabawuti osunthika, mabawuti owonjezera a nangula ndi ma bolt omangika.Malinga ndi mawonekedwe osiyanasiyana, imatha kugawidwa mu bawuti yophatikizidwa ngati L, bawuti woboola pakati 9, bawuti woboola pakati pa U, bawuti wowotcherera ophatikizidwa ndi bawuti pansi.
Chachiwiri, kugwiritsa ntchito ziboliboli za nangula Maboliti a nangula osasunthika, omwe amatchedwanso ma bolts amfupi, amagwiritsidwa ntchito kukonza zida popanda kugwedezeka kwamphamvu ndi kukhudzidwa.Nangula wosunthika, womwe umadziwikanso kuti bawuti yayitali ya nangula, ndi bawuti yochotsa, yomwe imagwiritsidwa ntchito kukonza zida zamakina zolemera ndi kugwedezeka kwamphamvu komanso kukhudza.Maboti a nangula nthawi zambiri amagwiritsidwa ntchito kukonza zida zosavuta zoyima kapena zida zothandizira.Kuyika kwazitsulo za nangula kuyenera kukwaniritsa zofunikira izi: mtunda wochokera pakati pa mabawuti mpaka m'mphepete mwa maziko sayenera kuchepera ka 7 m'mimba mwake mwa mabawuti a nangula;Kulimba kwa maziko a mabawuti omwe amayikidwa mu nangula yakukulitsa sikuyenera kuchepera 10MPa;Sipadzakhala ming'alu mu dzenje lobowola, ndipo chisamaliro chiyenera kuperekedwa kuti tipewe kubowola kuti zisagwirizane ndi zitsulo zazitsulo ndi mapaipi okwirira pa maziko;Kutalika ndi kuya kwa dzenje lobowola ziyenera kufanana ndi bolt ya nangula wokulitsa.Bonding nangula ndi mtundu wa bawuti wa nangula womwe umagwiritsidwa ntchito kwambiri m'zaka zaposachedwa, ndipo njira yake ndi zofunikira zake ndizofanana ndi zokulitsa bawuti ya nangula.Koma pamene kugwirizana, tcherani khutu kuwomba kunja sundries mu dzenje, ndipo musakhale yonyowa pokonza.
Thrid, Njira Zoyikira Zopangira Nangula Njira imodzi yophatikizira: pothira konkire, lowetsani ma bolts a nangula.Pamene nsanjayo imayang'aniridwa ndi kugubuduzika, bolt ya nangula iyenera kuikidwa kamodzi.Njira yosungiramo dzenje: zida zili m'malo, mabowo amatsukidwa, mabawuti a nangula amayikidwa m'mabowo, ndipo zida zitayikidwa ndikuyanjanitsidwa, zida zimatsanuliridwa ndi konkriti yamwala yopanda shrinkage yomwe ili pamtunda umodzi kuposa. maziko oyambirira, omwe ali ndi tamped ndi opangidwa.Mtunda wochokera pakati pa bawuti wa nangula mpaka m'mphepete mwa maziko suyenera kukhala wochepera 2d (d ndi m'mimba mwake wa bawuti ya nangula), ndipo usakhale wochepera 15mm (pamene D ≤ 20, sayenera kuchepera 10mm) , ndipo sayenera kuchepera theka la m'lifupi mwa mbale ya nangula kuphatikiza 50mm.Pamene zofunikira pamwambapa sizingakwaniritsidwe, njira zoyenera ziyenera kuchitidwa kuti zilimbikitse.Kutalika kwa mabawuti a nangula omwe amagwiritsidwa ntchito pamapangidwewo sayenera kuchepera 20mm.Zikachitika chivomezi, mtedza wapawiri udzagwiritsidwa ntchito kukonza, kapena njira zina zogwira mtima ziyenera kutengedwa kuti ziteteze kumasula, koma kutalika kwa nangula kwa ma bolts kudzakhala kotalika kuposa momwe sikunachite chivomezi.
