Izinhlelo Zokubhoboza Eziqhulwini

Ukuqedwa kokufaka i-Self-Drilling Anchor (SDA) kuyindlela yokwakha ethile kwezobunjiniyela bezinhlaka ezibucayi enezidingo ezinkulu emisebenzini yokwakha ezisekelwa phansi, ukuvuselelwa kwemigqa, nezicelo zokuphakanyiswa komhlaba. Izinsiza zokufaka igruout zezigaba ze-SDA zidlala indima ebalulekile ekuqinisekiseni izixazululo zokuxhumanisa ezihlala njalo ezihlanganisa umhlaba noma izindonga ezimangalisayo ezihambisana nezitezi ezinqanda, zigweme ukungaphumeleli kwezakhiwo, ukuhamba kwesisekelo, nokulimala kwesakhiwo okuhlobene nokuhlanza. Le ntuthuko ifaka inqubo ephelele yokufaka igruout ngesikhathi sokuhamba kwe-SDA, lapho izinhlelo zokufaka igruout ngok pressure ephezulu zifaka igruout ngesikhathi esifanayo nezinyathelo zokubhola, zakha indlela yokuphakanyiswa eyodwa ehlanganisa ithuluzi le-anchor, umzimba wegrout, nomhlaba osekelayo kungene ngokwakha. Indlela yokufaka igruout ye-SDA ibandakanya izindlela zokufaka igruout eziqhubekayo noma ezihambekayo ezilungiswe kumhlaba nezimo zezimila ezitholwa ngesikhathi sokuhamba kokubhola. Izinsiza zokufaka igruout ze-SDA kumele zenze umoya ophethwe kahle nokuhamba ukuze kuqinisekiswe ukuhleleka okuphelele kwensika yegrout ngaphakathi kweziqu, kungaba emhlabathini wezinsila, emnyangweni ophakanyisiwe, emadwaleni alimele noma emhlabeni oyinqaba. Izinsiza ezivamile ezisetshenziswa zifaka amaphampu anokuphakama okuphakeme, amaphampu okucindezela, kanye nezinhlelo zokufaka igruout zenzileyo ezisekela amamoleku aphezulu edinga ukukalwa okwenziwe ngezinsuku ezinzima zokuqina komgqomo nezithako ezipezulu zokudluliselwa komthwalo ophezulu. Izikhungo zokuhlanganisa neziteshi ze-flocculant ziqinisekisa ukujula okulinganayo kwegrout, kanti iziteshi zokufaka igruout nezinhlelo zamaphampu ziqinisekisa ukuhamba okungaguquki kwenye yeziqu zokuqonda, zifaka ubuchwepheshe obuhlobene ne-pressure namavolumu adingekayo ukuze ukwakhiwa kwe-SDA kuzungeze imikhakha yokuhlala engama-mitha angama-50 ngaphansi komhlaba. Izicelo zokufaka igruout ye-SDA zigcwele ezinkundleni ezihlukahlukene zokwakha lapho ukubaluleka kokuzinza kwezigodi nokuphakanyiswa komhlaba okuhlala njalo kubalulekile. Ekwakheni izinqaba nasekuqedeni izinkinga zokuqala, izinzwa ze-SDA ezinezinsiza zokufaka igruout eziphezulu zigwema ukuhamba kwangaphakathi nokwakha izikhala ezibhekelelwe isikhathi eside semishini yokwakhiwa. Imisebenzi yokumba kanye nezinsizakalo eziphansi zasezindaweni zisebenzisa ukufaka igruout ye-SDA ukuze kuseke izitobhi, kuqede ukudala, futhi kuvikela ukuvaleka kumhlanga wezindonga ezilula. Ubunjiniyela bezinhlaka zezakhiwo eziphakeme, iziqu, noshintsho olubaluleke kakhulu luhlala lusebenzisa izinhlelo ze-SDA ukuze kuqinisekiswe izisekelo ezindaweni eziphakeme nokunikeza ukuzinza okuhambisanayo ezimeni ezihlukahlukene zomhlabathi. Ukuqedela izinkinga zamagquma, ukufaka izindonga ezibambekayo, nezinsiza zokugqugquzela umhlaba zidinga izinsiza zokufaka igruout ezithembekile ukuze kutholakale umphumela wokuthuthuka komthwalo nokuhlala kwesikhathi eside okudingekayo kwezixazululo eziqhubekayo. Inqubo yokufaka igruout okufanele ihambisane nezimo zomhlaba eziye zatholwa kuhlanganisa nezinsila ezihamba kalula ezidinga ukuhamba okuphakeme, izinsila ezingaphumeleli ezinciphisa ukwamukela kwesisu, nezindonga eziphukile ezidinga ukumiswa okuqukethe igruout nokusebenza okuhle. Izpecifications zezinsiza zokufaka igruout ze-SDA zihlala zihlelelwa izici ezithile zephrojekthi ezihlanganisa umthwalo wokwakha ama-anchor, ubude nokuma kwezithupha, ubude bezikhathi zokufaka, nezici zokuwina komhlaba. Abakhi be-SDA abaqeqeshiwe bakhetha imishini yokubhola ethuthumayo efakwe ezikhungweni zokufaka igruout ezikhethekile, izinhlelo zokulandelela pressure, kanye nemizamo yokuthola idatha ngesikhathi esifanele ukuhlinzeka ngendlela yokuhlola izinga lokwakha nezidingo ze-geotechnical design specifications. Ukudluliswa kokufaka igruout ye-SDA ukuphumelelayo kuqinisekisa ukusebenza okwethembekile kwe-anchor, impilo yesevisi ebanzi, kanye nokuhambisana nezinqamuleli zendlela yokwakha nezindinganiso ze-geotechnical engineering ezibhekele impilo yokwakha ehamba phansi nokusebenza kwezindawo zokwakha kulo mkhakha.
