ukuze kube ne-cluster DTH

Ithuluzi elibizwa nge-Cluster DTH displacement piling limelela indlela ethuthukisiwe yokwakha imikhakha emikhulu lapho izimbobo eziningi zikhunjulwa phansi ziqhuba eduze ukuze kwakhiwe uhlelo lwe-base olwedlule. Le ndlela ihlanganisa ukusebenza kahle kwetekhnoloji ye-DTH hammer drilling kanye nomgomo we-displacement piling, lapho inqubo yokukhuhla ibhucungela umhlabathi ngokuhlanganyela futhi ihlola umhlabathi ezungeze umjikelezo wezimbobo. Ngokwehlukile kokwakha okujwayelekile kwepile noma i-diaphragm wall, i-cluster DTH piling inikeza izinto ezinkulu ngokweziqu zokulawula ukuvuvukala, ukunciphisa umsindo, nokukhawulela kumasayithi asezindaweni ezikhanyayo. Le ndlela ibalulekile kakhulu kumaphrojekthi enjineli ye-geotechnical lapho i-piling ejwayelekile yokuphakanyiswa ingase ibe yinkinga ngenxa yezithiyo zemvelo noma izimo zomhlaba ezidinga ukulawulwa kahle kokuhamba komhlabathi nokuzinzelekile. Ukuphumelelisa i-cluster DTH displacement piling kudinga amathuluzi akhethekile kufaka phakathi izinkanyezi eziphezulu ze-down-the-hole ezihlanganiswe nezikhwepha zomoya noma eziphathekayo, izinhlelo zokumisa ezihlanganisiwe, kanye nezinsiza zokuphakamisa izinto zokwakha ze-slurry noma okutremie. Le ndlela yokuhlanganisa ihilela ukusika izimbobo eziningi ngokubala kahle ubude—ngokuvamile phakathi kuka-1.0 no-2.0 amamitha—ukuze kuqinisekiswe ukuhamba komhlabathi okuhle nokudluliswa komthwalo phakathi kwe-shaft ezakhele. Inqubo yokukhuhla idala ukuhamba okuqhubekayo komhlabathi phakathi kwezimbobo, okwandisa ingcindezi ye-lateral ezindaweni ezizungezile futhi kufinyelela ubuningi obuphezulu kuhlelo lwezikhukhula. Abasebenzi kumele bagcine ukulawula ngokucophelela ubude, bahlolisise izimo zokukhuhla ezifana no pressure lomoya kanye nesivinini sokuzungezisa, futhi bahlanganyele nabakwenzi bomhlaba ukuze kuqinisekiswe ukuvinjwa komhlabathi okuhle. Le teknoloji ikakhulukazi iyasebenza emhlabathini ohlanjululiwe, i-sand esheshayo, kanye nezimpahla ezixubile lapho izinzwa zokuhamba zibandakanya ukuthuthukiswa kwemveliso yokuphatha ngaphandle kokufuna ukwelashwa komhlaba okukhulu. I-cluster DTH displacement piling ifanele kahle kumaphrojekthi axhumene nezakhiwo ezithintekayo, izinhlelo zokubuyisela emuva ezindaweni ezakhiwe, kanye nezindawo ezinezidingo ezinzima zesayensi yomhlaba. Ukusetshenziswa okuvame kakhulu kufaka phakathi izikhunta zezilwandle, izakhiwo zomgwaqo, izisekelo zezimboni, ukwakhiwa kwama-high-rise, nezinhlelo zokusebenza zamandla avuselelekayo lapho kunandaba kakhulu ukwakheka komthwalo okuqinile okuphumelela ngokuncane kokwaziswa kokuvuvukala. Le ndlela ibonakala ikwazi kahle ezindaweni ze-alluvial, umhlabathi we-lacustrine, kanye nezindawo zolwandle lapho i-piling ejwayelekile ingaholela ekubeni umehluko omkhulu noma izinkinga zokuhlanganiswa. Izinzuzo zemvelo—ukunciphisa umsindo, ukuvuvukala, nokungcoliswa komoya uma kuqhathaniswa nezindlela zokuxhumana ezijwayelekile—zenza i-cluster DTH displacement piling ithandwa kakhulu emaphrojekthini okuthuthukisa izindawo ezikhulayo nemigwaqo enezimo zemvelo ezithintekayo. Uhlaka lwe-cluster luthuthukisa kokubili ukusebenza kwemali kanye nezobuchwepheshe ngokusabalalisa imithwalo yokwakha phakathi kwezikhukhula ezihlobene kakhulu ngenkathi kunciphisa ukuphazamiseka komhlaba nokugcina isikhathi sephrojekthi sikhona. Ukuphumelelisa kudinga uphenyo olunembile lwe-geotechnical, ukuhlaziywa kokukhuhla komhlabathi, kanye nokwakhiwa kwezinjini ezithathela phezulu kwemisebenzi yokuhamba, ukuthuthukiswa kokuphatha, kanye nezibikezelo zokwakhiwa. Le ndlela ibamba ngempumelelo nezinsiza zamuva kanye nezinhlelo zokuhlola, ivumela ukuqinisekiswa kwekhwalithi ngesikhathi sokukhuhla futhi inikeze idatha engahlukanisiwe ekukhishweni kokuphatha nasekuqondeni kungabi nakuhlupheka kokuqinisekisa kuya ekwakhiweni nasekuqinisekisweni kwemibhalo.
