Indlela yokucindezela

Indlela yokucindezela imele ubuchwepheshe obukhethekile bokushaya amaphayiphi obuchwepheshe bezisekelo ezijulile lapho amaphayiphi ecindezelwa kancane kancane emhlabeni esebenzisa amandla aphezulu alawulwayo. Ngokuphambene nezinhlelo zokushaya amaphayiphi ezisebenzisa ukuqubuka noma umphumela, indlela yokucindezela isebenzisa uhlelo lwama-anchorage okuphendula olufakwe ngaphambi, oluzenza indawo yokuphendula ezinzile evimba amandla acindezelwe kumaphayiphi. Le ndlela ivumela abaqashisi ukuba bafake amaphayiphi e-H enziwe sthelas, ama-tube esithathu, kanye namaphayiphi aqinisiwe ngekhonkrithi ngokulawula kahle ukujula nokuphazamiseka okuncane komhlaba. Uhlelo lokushaya amaphayiphi lokucindezela luwusizo ikakhulukazi ezindaweni zasemadolobheni nasezindaweni zokwakha ezibucayi lapho imingcele yokuvuvukala nokukhala kubalulekile. Njengoba le ndlela ikhipha umthelela nokuphazamiseka okuncane okuhlobene nokushaya ngesikhwama, iyanciphisa kakhulu umthelela kwemvelo ezakhiweni ezisemhlabeni, emalinezikhwama, nasemithonjeni engaphansi komhlaba ngenkathi igcina izinga lokungena kwamaphayiphi lingashintshi kunoma yikuphi ukuphikisana komhlaba. Indlela yokucindezela isebenza kuma-geo-technical conditions ahlukahlukene, ukusuka enkundleni ethambile ye-clay ne-silty kuya kumsandla ocilikile kanye nezinhla ezixubile, iyenza ibe yinqaba kakhulu kumaphrojekthi ezisekelo ezindaweni zasemadolobheni ezinzima. Izinhlelo ze-anchorage yokuphendula zingakwazi ukukalwa nokuhlelwa ukuze zihambisane nezimo zomhlaba ezithile kanye nezidingo zomthwalo wamaphayiphi, kuvumela imishini ukuthi igcine izinga lokushaya elilawulwayo noma ngabe izinhla ezinzima zokungena. Le teknoloji ivumela kokubili ukufakwa kwamaphayiphi amasha nokukhipha amaphayiphi akhona ngokuphendula kPressure ye-hydraulic, ixhasa izinhlelo zokulungisa indawo nokuvuselelwa kwezokwakha. Izinsiza zokucindezela ezisezingeni elisha zihlanganisa izinhlelo zokuhlola umthwalo nezikhuphukeli, zinika idatha yesikhathi sangempela ngomphumela wokungena, ukujula kwamaphayiphi, kanye ne-structural integrity kuyo lonke uhlelo lokufakwa. Izicelo ze-press-in piling zifinyelela ezindaweni zokuhlala, ezimbonini, nezizinda zezimali, kuhlanganisa ukwakhiwa kwezindlu eziningi, imisebenzi yeziqhingi zezinyathelo, nezinhlelo zokuthuthukisa lapho ukuphonswa okujwayelekile kungaholela ekuphazamisekeni noma ekukhuleni okungamukeleki. Le ndlela ibonakala iyasebenza kakhulu ezindaweni ezinabantu abaningi, eduze kwezibhedlela nezinsizakalo ezibucayi, nasezinhlelweni ezinomthelela omkhulu wokwakha ebusuku. Njengoba ama-anchorage okuphendula aphelezela umthwalo phezu kwamavolumu omhlaba amakhulu, indlela yokucindezela ingasetshenziswa ezindaweni ezivalekile lapho amaphayiphi noma amadokodo aphendula ejwayelekile engafaneleki. Le ndlela yokushaya amaphayiphi iphinde ixhase ukujula kanye nezinsizakalo zokulungisa izisekelo lapho ukunemba nezici zokudlula okuphansi kuvimbela ukwehla kwezakhiwo eziseduze. Uhlobo olutholakale lwetemu yokucindezela lwe-technology lunciphisa ukuphazamiseka komhlaba, kwehlisa izingozi zomhlaba ophakeme nokunyakaza komhlaba okungabeka engcupheni imisebenzi eseduze nezindlu nabanye, okwenza kube yisixazululo esithandwayo sokwakha izisekelo ezijulile kumaphrojekthi anzima edolobheni nasezindaweni zokwakha ezinobungozi bemvelo.
