AmaRigs anokufinyelela okwandisiwe

Iziqinisekiso zokwakha ezikhulisiwe zihlinzeka ngezixazululo zempahla ezikhethekile zokufaka ama-pile ngokunembile ezindaweni ezingezinhle ze-geotechnical lapho izithiyo zesikhala nezinkinga zokufinyelela zidinga amakhono okwandisa okuyingqayizivele. Lezi ziqinisekiso zenzelwe ukuthuthukisa umkhawulo wokusebenza kwezinhlelo zokufaka ama-pile eziyinqaba, okuvumela abadala ukuba bafake ama-pile emqondweni ezindaweni ezincishisiwe, eduze kwezindlu ezikhona, ngaphansi kwezithiyo ezinezingqondo, nasemaphehlweni anzima lapho imishini ejwayelekile yokudrill noma yokushaya ama-pile ingasebenzi kahle. Uhlaka olukhulisiwe lwe-mast, ngokuvamile luhlanganiswe nezinsiza zokuhola ama-pile, luvumela ukufakwa kwephezulu kanye nokugcina ubungako bokuma ngenkathi kugcinwa amazinga wokufakwa okuphathwa kahle okuhlosiwe kuhambo lwezokwakha. Indlela yokusebenza yezinkumbulo zokwakha ezikhulisiwe igxile ekuphathweni kokukhishwa okukhanyayo noma okuphakathi kokukhishwa kwe-pile, lapho izinhlelo ze-hydraulic zifaka ama-pile ngaphansi komhlaba ngempahla ethile ehleliwe edlulele phezu kwezakhiwo zomhlaba. Le ndlela iphikisana kakhulu nezindlela zokufaka ama-pile ezisuselwa ekuqhamukeni, inikeza izinzuzo ezinkulu ezindaweni ezibucayi okubandakanya ukuhlala eduze kwezindlu ezisebenzayo, izindawo ze-archaeological, nezindawo ezinokukhululwa kokukhala okuphansi. Ikhono lokufaka elandisiwe lihlola ukufakwa kwezinhlobo ezahlukene ze-pile—kuhlanganise ne-H-sections zensimbi, ama-pile tubular, nezinto zekhonsathi ezilungiselelwe—kanye nosayizi ukusuka kuma-micropiles aphansi kuya kuma-pile amakhulu, okuyinto ngayinye edinga ama-profiles alungile okukhishwa kwezithako nezinhlelo zokuphendula. Izinsiza zokuhola ama-pile zisebenza njengezingxenye eziyisisekelo kule ngxenye, ezinikeza ukuvinjelwa okuphelele nokugcina ukuvumelana nezinga lokuhlola kulo lonke uhlelo lokufaka, ikakhulukazi lapho kuhlangene nezinto ezinde nezinhle eziyingozi zokuphuka noma lapho ukufakwa ngokunembile kukhombisa ukusebenza kwesakhiwo. Izinhlelo zezingcindezi zomhlaba eziphathwa kahle zokwakha ezikhulisiwe ziphumelele ezimeni ezinzima ezihlukahlukene: umhlaba wobumba obuthakathaka obidinga izindlela zokunyakaza okulawulwa, izinkalo ezihlukene ezidinga ukwakhiwa kokwenziwayo, izimo ezinhle ezinzima ezidinga ukuphathwa kwezimali ezibulalayo, nezindawo ezinzima lapho i-vibration noma ukuvuza komhlaba kubeka ubungozi obungamukeleki kwezokwakha eziseduze. Lezi ziqinisekiso zikhanga kakhulu emaphaketheni okwakha ama-brownfield lapho izimo zomhlaba ezingaqinisekisiwe nezinsiza ezixhunywe ngaphansi zidinga izinhlelo zokusebenza ezisebenzayo, eziphumelelayo. Ukuklanywa kokukhulisiwe kuyvaluable ekuqinisekiseni izinto zokwakha ezisematheni umphakathi, izinhlelo zokubuyiselwa kwezokwakha, nezinsizakusebenza eziphathwa kahle lapho indawo yokunyakaza ifinyelela phansi. Izinhlelo ezikhulisiwe zamanje zifaka ukudlalwa kwe-load ethuthukisiwe, ukuqapha ukuhamba ngesikhathi sangempela, kanye nokulungisa okuzenzakalelayo, okuvumela abakhiqizi ukuba bagcine izinga lokufaka okuphezulu ngenkathi befaka impendulo ye-geotechnical ethile phakathi kohambo lokufaka. Kubadali abaphatha izinhlelo zokwakha ezinzima edolobheni, amaphrojekthi okubuya kwezokwakha, kanye nezinkinga zemifuziselo ezindaweni ezithubile, iziqinisekiso zokwakha ezikhulisiwe ezihlanganiswe nezinhlelo zokuhola ama-pile ezivumelanayo zikhombisa amandla obuchwepheshe abalulekile ukuze kufezwe izidingo zezakhiwo kanye nezinhlelo zokuphatha indawo.
