Imishini Yokusekela

Imishini yokweseka represents izinhlelo ezibalulekile zokuxhasa nezinsiza ezivumela ukwenziwa kahle kwemisebenzi yokwakha ezinzulu nasezobunjiniyela be-geotechnical. Nakuba imishini eyinhloko yokubhola nezinsiza ezifakwe ziqala zibe yisisekelo sokwakhiwa kwezinhlaka, imishini yokweseka iqinisekisa ukusebenza kahle ngokusebenzisa imisebenzi eyakhelwe njenge ukuphathwa kwe-slurry, ukukhiqizwa kwengcindezi, ukuhlinzekwa kwamandla, futhi ukuphathwa kwezinto. Lezi zinhlelo zokusekela zibalulekile ezifundeni zonke ezinkulu zezinhlaka ezinzulu, okuhlanganisa i-bored piling, ukuhlinzeka nge-diaphragm wall, i-micropiling, kanye nezindlela zokuphucula umhlaba. Ukuhlanganiswa kwemishini yokweseka echazwe kahle kuthinta ngqo isikhathi sephrojekthi, ukunembile kokubhola, kanye nekhwalithi yokwakha yonke ezimweni zomhlabathi eziyinkinga kanye nezakhiwo ze-geological eziyinkimbinkimbi. Izinhlelo zokwelapha i-slurry nokuhamba zimi yinoma yisiphi sezigaba ezibalulekile zemishini yokweseka ekwakhiweni kwezinhlaka. I-bentonite slurry isetshenziswa njalo ekwakheni i-bored piling nase-diaphragm wall ukuze ibambeleze izithiyo, ixhase odongeni lwemiphato, futhi ithuthukise ukususa iziqhumane ezivela ezinzulwini. Izitshalo zokuhlukanisa i-slurry, okuhlanganisa nezikhumbuzo ze-decanter, ama-skrini aphumayo, kanye nezitsha zokuhlala, ziqinisekisa ukuphinda kusetshenziswe nokuvuselelwa kweziqukathi zokubhola, kwehlisa izindleko zokusebenza ngenkathi kugcinwa ukusebenza kokubhola. Imiphumpu ye-grouting nokuhlanza iletha ingcindezi ye-hydraulic ngemisebenzi ye-tremie grouting, ukuvuselela imiphato, kanye nokuhlanza izindawo ezingcolile, nezincazelo ezihluka ngokuya ngezinga le-slurry, ukujula kwemikhondo, kanye nezimo ze-geological. Ngokufanayo, imiphumpu yokufaka ingcindezi ephezulu isekela ukuvuselelwa komhlaba, ukujolisa komhlaba, kanye nezicelo ze-fracture grouting ezindaweni ezilukhuni noma eziphukile. Ukukhiqizwa kwamandla nezinhlelo ze-pneumatic zidala i-backbone yokusebenza kwemishini endaweni, ikakhulukazi ezindaweni ezikude noma lapho ukuxhumana kwe-grid kukhawulelwe. Ama-generator e-diesel ahlinzeka amandla kagesi aphelele wokusebenza kwemishini yokubhola, ukukhanyisa, kanye nezinye izinsiza, kanti ama-compressor ama-rotary ahlinzeka ngempahla ye-compressed air yemishini ye-pneumatic, amathuluzi okuphula, nezindlela zokubhola ze-air-lift. Imishini yokususa amanzi, okuhlanganisa imiphumpu ephuma emanzini nezinhlelo ze-wellpoint, iphathe ukulawula amanzi angaphansi emhlabathini ogcwele futhi igcine izimo zokusebenza ezizinzile ezindaweni zokumba. Lezi zinhlelo zibalulekile emisebenzini yokubhola ezindleleni ezine-matle, ezindaweni ze-aquifer, nasezindaweni ezinezizinda eziphezulu zokuphuma amanzi ezivame ukufakwa emigqonyeni, emhlabathini aluvumelani, nasezinhlakeni ze-coastal. Imishini yokweseka ifaka futhi imishini yokuphatha kanye nokulungiselela izinto ezibalulekile kwi-logistics ye-structural. Izitshalo zokuhlanganisa zishaya futhi zixuba izixazululo ze-cementitious grout ukuze kuhlangatshezwane nezincazelo ezithile zokuvuselelwa kwezinhlaka kanye nokugroutu ye-pile base. Ama-conveyor e-aggregate nezinhlelo zokuphuma zithutha iziqhumane zokubhola ezindaweni ezintula ukuhamba, zigcine indawo ihlanzekile futhi ziqinisekisa ukusebenza kahle. Iziqhamo ze-mast, ama-rotary heads, nemathuluzi okuphula zenza imishini yokubhola eyinhloko ihambisane nezindlela ezikhululekile zokwakha ezinjengeziqhamo ezizenzekelayo, ukubhola kwe-hollow-stem auger, kanye nezindlela zokubhola ze-cable percussion. Ukukhetha okufanele nokuhlanganiswa kwemishini yokweseka kuqinisekisa ukuhambisana nezincazelo ze-geotechnical design, imithetho evikela imvelo, kanye nezindinganiso zokwakha ezinzulu kumafinyo ahlukahlukene nezimo zomhlaba.
