Uhlolojikelele lwe-Anchor Hollow Steel Bars
Imigoqo yensimbi eyisikhonkwane engenalutho ikhiqizwa ngezigaba ezinobude obujwayelekile obuyi-2.0, 3.0 noma 4.0 m. Ububanzi obujwayelekile bangaphandle bemigoqo yensimbi engenalutho busukela ku-30.0 mm kuye ku-127.0 mm. Uma kunesidingo, imigoqo yensimbi engenalutho iqhutshwa ngamantongomane ahlanganisayo. Izinhlobo ezahlukene zokumba izinsimbi zomhlatshelo zisetshenziswa kuye ngohlobo lwenhlabathi noma idwala. Ibha yensimbi engenalutho ingcono kunebha eqinile enendawo efanayo ephambanayo ngenxa yokuziphatha kwayo kwesakhiwo okungcono kakhulu mayelana nokugoqa, ukuzungeza nokuqina kokugoba. Umphumela uba ukubopha okuphezulu nokuzinza okuguquguqukayo kwenani elifanayo lensimbi.

Izicelo Ze-Self Drilling Anchor Rods
Eminyakeni yakamuva, ngesidingo esikhulayo sokusekelwa kwe-geotechnical, imishini yokumba ibilokhu ivuselelwa futhi yathuthukiswa. Ngesikhathi esifanayo, izindleko zabasebenzi nezokuqasha ziye zanda, futhi izidingo zesikhathi sokwakha ziye zanda kakhulu. Ukwengeza, ukusetshenziswa kwezinti ezizibhobozayo ezingenalutho ezimweni ze-geological ezivame ukuwa kunemiphumela emihle kakhulu yokubambelela. Lezi zizathu ziholele ekwandeni kokusetshenziswa kwezinti zokuzibhoboza ezingenalutho. Izinti zehange ezizibhobozayo zisetshenziswa kakhulu kulezi zimo ezilandelayo:
1. Isetshenziswa njenge-anchor rod egcizelelwe ngaphambili: isetshenziswa ezimeni ezifana nemithambeka, ukumba ngaphansi komhlaba, kanye ne-anti ezintantayo ukuze kushintshwe izintambo okusetshenzwa kulengwa kuzo. Izinti zokuzibhoboza ezingenalutho zimbozwa kuze kufike ekujuleni okudingekayo, bese kwenziwa i-grouting yokugcina. Ngemuva kokuqina, ukungezwani kuyasetshenziswa;
2. Isetshenziswa njengama-micropiles: Izinsimbi zokuzimbela eziyizimbotshana zehange zingabholwa futhi zigaywe phansi ukuze zenze ama-micropiles, avame ukusetshenziswa ezisekelweni zombhoshongo wezitshalo zamandla omoya, isisekelo sombhoshongo wokudlulisa, isisekelo sokwakha, isisekelo senqwaba yodonga, isisekelo senqwaba yebhuloho, njll;
3. Isetshenziselwa izinzipho zenhlabathi: evame ukusetshenziselwa ukusekela i-slope, esikhundleni sezintambo zensimbi ezijwayelekile ze-anchor, futhi ingasetshenziselwa ukusekela umgodi ojulile wesisekelo;
4. Isetshenziselwa izinzipho zamadwala: Kwamanye amatshe emithambekeni noma emhubheni anesimo sezulu esibi kakhulu noma ukukhula okuhlangene, izinti zokuzibhoboza ezingenalutho zingasetshenziselwa ukubhoboza nokuhlanganisa ukuze kuhlanganiswe amatshe amatshe ukuze kuthuthukiswe ukuzinza kwawo. Isibonelo, amatshe emithambeka yemigwaqo emikhulu kanye nojantshi ojwayele ukuwa angaqiniswa, futhi izindawo zokubeka amapayipi ezivamile nazo zingashintshwa ukuze kuqiniswe lapho kuvuleka khona umhubhe;
5. Ukuqinisa okuyisisekelo noma ukuphathwa kwezinhlekelele. Njengoba isikhathi sosekelo sesistimu yosekelo lwe-geotechnical yasekuqaleni sikhula, lezi zakhiwo zokusekela zingase zihlangabezane nezinkinga ezithile ezidinga ukuqiniswa noma ukwelashwa, njengokuguquguquka komthambeka wokuqala, ukuhlaliswa kwesisekelo sokuqala, nokuphakanyiswa kwendawo yomgwaqo. Izinti ezizibhobozayo ezingasetshenziselwe ukubhoboza emthambekeni wokuqala, isisekelo, noma indawo yomgwaqo, njll., ukugxumeka nokuhlanganisa imifantu, ukuvimbela ukwenzeka kwezinhlekelele zemvelo.
