Izinsiza Zokuhlanza (Top Feed)

Ama-probes ahlwengayo anezindlela zokudla eziphezulu ayingxenye ebalulekile yokuhlola umhlaba nokuthuthukiswa komhlabathi emkhakheni wezokwakha izisekelo ezijulile. Lezi zinsiza ezikhethekile zisetshenziselwa ukuhlola izimo ezingezansi komhlaba, ukuthola amandla ophakamisa umhlabathi, nokuhlonza ukujula okuphumelelayo kokwakhiwa kwezisekelo nemisebenzi yokuthuthukiswa komhlaba. Ama-probes ahlwengayo anezindlela zokudla eziphezulu asebenza ngokwethula izinto noma izinsiza zokuhlola ukusuka phezulu komshini wokubhoboza enyangeni, esebenzisa ukuhamba okubusisiwe ukuze kuthunyelwe ezindaweni ezihlukene zomhlabathi. Lokhu kulungiselelwa kuvumela abathuthukisi bezokwakha uku gathersa idatha ye-geotechnical yesikhathi sangempela ngenkathi behlola impendulo yomhlabathi kumandla ahlwengayo, kunikeza ulwazi olubalulekile emsebenzini wezisekelo olandelayo kanye nezinhlelo zokwelapha umhlaba. Lezi zinsiza zibalulekile ikakhulukazi ezifundweni zokuqala zokuhlola izindawo lapho ukuhlola okusheshayo kwezimpawu zomhlaba kuyadingeka ukuze kuthuthukiswe izinqumo zokwakha izinhlelo zokuphakamisa, amakholomu amatshe, kanye nemisebenzi yokucindezela umhlabathi. Ukusebenza kwezezimali kwama-probes ahlwengayo kubandakanya ukufaka ukuphazamiseka okuphathwayo nokpressure (prung) phezulu kuzinhlu ezihlanganisiwe njengoba evola emalungwini omhlaba ahlukahlukene. Lezi zinsiza zisebenza kahle ezimweni ezihlukene zomhlaba, okuhlanganisa i-clay, i-silt, i-sand, kanye nemisebenzi yokuxuba umhlaba, zishintsha ezithombeni zendawo emkhakheni wokuhlola ngaphansi komhlaba. Abathuthukisi bezokwakha basebenzisa idatha ye-probe ukuze bahlonze ukuhamba phakathi kwezinye zomhlabathi, bakhombise ama-lenses aqinile, futhi baphonsele izinga lempilo emanzini, konke okuthinta ngqo idizayini nezokufaka izisekelo. Ukuhlinzekwa kokudla phezulu kuvumela ukufakwa kwezinto nokuhlolwa kahle ngaphandle kokudinga ukuhlinzeka okuningi, kwenza le ndlela ibe nezezimali kuzihloko ezinkulu. Ama-probes ahlwengayo akhiqiza ukuphazamiseka okuncane kumhlaba owaqondile uma kuqhathaniswa nezindlela ezibeni, kugcina isakhiwo semvelo sezinto ezisemhlaba futhi kunikeza ukukhishwa okuqondile kwezimo zomhlaba zangempela ezibhekene nokufakwa kwezisekelo ezisemthethweni. Izicelo zama-probes ahlwengayo zihlanganisa imikhakha eminingi ezokwakha izisekelo ezijulile nasekukhuleni komhlaba, okuhlanganisa ukuthuthukiswa kwezohwebo, ukwakha kwezinsizakalo, amaphrojekthi wezokusebenza, nezicelo zezimali eziyadinga ukuthuthukiswa okukhulu komhlaba. Ngaphambi kokwenza ukuhlelwa kwe-vibro, ukufakwa kwamakholomu amatshe, noma izinhlelo zokucindezela ahlwengayo, abakhiqizi bathumela ama-probes ukuze bachaze izimo ezingezansi komhlaba futhi bashayele izakhiwo zezezimali ezidingekayo ukuze kuqinisekiswe okukhona. Idatha etholelwe ngama-probes ahlwengayo ithinta ngqo ukukhethwa kwezinsiza ezifanelekile zokuthuthukiswa komhlaba, ukujula kokwelashwa, nezincazelo zezinto. Lezi zinsiza zisebenza njengamathuluzi abalulekile ngaphakathi kwezindawo zokuqhubeka komhlaba, zisekela izinqumo ezinhle zokuphucula ukusebenza kwezisekelo, zinciphisa ingozi yokwakha, futhi ziqinisekise ukuhambisana nezincazelo zokwakha ze-geotechnical. Ukuhlanganiswa kokuhlola ama-probes ahlwengayo nokwenza ukuphathwa komhlaba okukhona kuvumela abakhiqizi ukuhlinzeka ngezixazululo eziphezulu zezekelo ngenkathi kugcinwa ukuthengeka kwemali nezinhlelo zamaphrojekthi ezicelo ezinzima ze-geotechnical.
