Ukubuka konke kwe-Anchor Hollow Steel Bars
Imigoqo yensimbi engenalutho e-anchor ikhiqizwa ngezigaba ezinobude obujwayelekile obungu-2.0, 3.0 noma 4.0 m. Ububanzi obujwayelekile bangaphandle bemigoqo yensimbi engenalutho buqala ku-30.0 mm kuya ku-127.0 mm. Uma kudingeka, imigoqo yensimbi engenalutho iyaqhubeka namantongomane okuhlanganisa. Izinhlobo ezahlukene zezingcezu zokubhoboza ezizidelayo ziyasetshenziswa kuye ngohlobo lomhlabathi noma idwala. I-bar yensimbi engenalutho ingcono kune-bar eqinile enendawo efanayo yokunqamula ngenxa yokuziphatha kwayo okungcono ngokwesakhiwo ngokugoba, ukujikeleza kanye nokuqina kokugoba. Umphumela uba ukuqina okuphezulu kokugoba kanye nokuguquguquka kwenani elifanayo lensimbi.

Ukusetshenziswa Kwezinduku Zokubhoboza Izinsimbi Zokuzishayela
Eminyakeni yamuva nje, njengoba isidingo sokusekelwa kwe-geotechnical sikhula, imishini yokubhoboza ibilokhu ivuselelwa futhi ithuthukiswa. Ngesikhathi esifanayo, izindleko zabasebenzi nezokuqasha zikhuphukile, futhi izidingo zesikhathi sokwakha ziye zanda kakhulu. Ngaphezu kwalokho, ukusetshenziswa kwezinduku ze-hollow anchor ezizibhoboza ngokwakho ezimweni ze-geological ezivame ukuwohloka kunemiphumela emihle kakhulu yokuzibopha. Lezi zizathu ziholele ekusetshenzisweni kabanzi kwezinduku ze-hollow anchor ezizibhoboza ngokwakho. Izinduku ze-hollow anchor ezizibhoboza ngokwakho zisetshenziswa kakhulu kulezi zimo ezilandelayo:
1. Isetshenziswa njengenduku ye-anchor ecindezelwe: isetshenziswa ezimweni ezifana nemithambeka, ukumba ngaphansi komhlaba, kanye nokungantanti ukuze kuthathelwe indawo izintambo ze-anchor. Izinduku ze-anchor ezingenalutho ziyabholwa zifinyelele ekujuleni okudingekayo, bese kwenziwa i-grouting ekugcineni. Ngemva kokuqina, kufakwa ukucindezeleka;
2. Isetshenziswa njengemibhobho emincane: Izinduku ze-anchor ezingenalutho zingabholwa bese zihlanganiswa phansi ukuze zakhe imibhobho emincane, evame ukusetshenziswa ezisekelweni zombhoshongo wesitshalo samandla omoya, ezisekelweni zombhoshongo wokudlulisa, ezisekelweni zokwakha, ezisekelweni zemibhobho yodonga egcinayo, ezisekelweni zemibhobho yamabhuloho, njll.;
3. Isetshenziselwa izipikili zenhlabathi: ivame ukusetshenziswa ekusekeleni ukuthambeka, ithathe indawo yezinduku zensimbi ezivamile zokusekela ukuthambeka okujulile, futhi ingasetshenziswa nasekusekeleni ukuthambeka okujulile komgodi wesisekelo;
4. Isetshenziselwa izipikili zamatshe: Kwezinye izindawo ezisemadwaleni noma emihubheni enesimo sezulu esibi kakhulu noma ukuthuthukiswa kwamalunga, izinduku zokuzibhoboza ezingenalutho zingasetshenziswa ukubhoboza nokuhlanganisa amabhlogo amatshe ukuze kuthuthukiswe ukuzinza kwawo. Isibonelo, izindawo ezisemadwaleni zemigwaqo emikhulu kanye nezitimela ezivame ukudilika zingaqiniswa, futhi izindawo ezivamile zamapayipi zingashintshwa ukuze kuqiniswe ezindaweni ezivulekile zemihubhe;
5. Ukuqinisa okuyisisekelo noma ukuphathwa kwezinhlekelele. Njengoba isikhathi sokusekela sohlelo lokusekela lwe-geotechnical lokuqala sanda, lezi zakhiwo zokusekela zingase zibhekane nezinkinga ezithile ezidinga ukuqinisa noma ukwelashwa, njengokuguqulwa komthambeka wokuqala, ukuhlaliswa kwesisekelo sokuqala, kanye nokuphakama kobuso bomgwaqo. Izinduku ze-anchor ezizibhobozayo zingasetshenziswa ukubhoboza emthambekeni wokuqala, isisekelo, noma umhlabathi womgwaqo, njll., ukuze kuhlanganiswe imifantu, ukuvimbela ukwenzeka kwezinhlekelele ze-geological.
