Imishini Yokubhoboza Eziqhulwini Eziqhutshwa Ngamathrekhi

Imishini yokudonsa efakwe kumathrekhi ibaluleke kakhulu emisebenzini yokuphimisa ye-micropiling yokwakha, ihlinzeka ngekhono lokudonsa elihamba phambili kumathrekhi avunyelwe emigwaqweni ukuze kufinyelelwe ezindaweni ezingezinhle zasemadolobheni kanye nezimo zendawo ezidinga ukufakwa kahle kwezingxenye ezincane zokwakha. Lezi zinhlelo zokudonsa ezikhethekile zanelisa ukuhamba okudingekayo kumaphrojekthi wesisekelo esijulile kanye nezinhlelo zokwakha, lapho imishini evamile yokuphimisa ingakwazi ukufinyelela ngenxa yokukhawulelwa kwesikhala, ukuphakama okukhawulelwe, noma izithiyo zokusebenza. Isetshenziswe kumathrekhi aphakathi nendawo kuya kumathrekhi anzima, lezi zikhungo zokudonsa zihlanganisa ikhono lokudonsa nokuhamba, kuvumela ukuhamba okusheshayo naphezu kokugcina ukusebenza ngokuphelele kokufaka ama-micropile kokubili ezintweni eziluhlaza nasezindaweni ezimnyama lapho ukuthuthukiswa kwenground kanye nokwakha izisekelo kubalulekile empumelelweni yephrojekthi. Imisebenzi ye-micropiling esebenzisa izikhungo zokudonsa ezihambayo ikhiqiza izindlela ezahlukene zokudonsa ezihambisana nezimo ezithile zendawo, kuhlanganise nokuqhuba okujikelezayo, izinhlelo zokuphikisana nokuqhuba, kanye nezindlela zokuphakanyiswa. Lezi zindlela ziqhuba ukufakwa kwamapile anediameter encane ngokuvamile aphakathi kuka-150 kuya ku-300 milimitha, kuvumela onjiniyela ukuthi baphathe izinselelo eziyinkimbinkimbi zokwenza ngcono umhlaba ngokusabalalisa umthwalo ngokuqondile nokuthuthukisa amamatrix alendawo akhona. Izikhungo zokudonsa zisebenza kahle emithonjeni ephumelelisa, imithombo ye-granular, uhlobo lomhlaba olugqashukile, kanye nezindonga eziqinile, kanye nokuguquguquka kwezinqubo zokudonsela okuvumela ukukhetha indlela efanele yokudonsa ngokususelwa ekwakhiweni komhlaba nezidingo zokuklama. Ubukhulu bezisebenzi buhlale buphansi uma kuqhathaniswa nezikhungo zokuphimisa ezivamile, okuthuthukisa ukusebenza kwendleko ezindaweni zasemadolobheni nasezindaweni zosuku lapho indawo yeqembu kanye noise yokusebenza ibonisa izithiyo ezinkulu kumasu anjengezemba ezijulile. Izicelo zezimoto zokudonsa ezihambayo zifaka ukwakha izisekelo kanye nemisebenzi yokulungisa izisekelo, lapho ukusabalala noma ukuhamba kwempahla kudinga ukufakwa kwezinsiza ezixhasiwe ngaphansi kwezakhiwo ezikhona ngaphandle kokuxhaphaza kakhulu. Lezi zikhungo zenza kahle emaphrojekthini wokwandisa izikhala zokuphila, ukuphakanyiswa izisekelo, ukulungiswa kokudlula ezinkundleni, kanye nezinqubo zokulungisa izinzwa lapho ukuthuthukiswa kwenziwa ukuvikela ukwehla okunenzuzo okukhulu. Izicelo zokuphinda zenzeke zikhombisa isahluko esibalulekile emakethe, njengoba izinhlelo ezihambayo ziqhuba emizileni ethile yokufinyelela, izindawo eziphakeme zokusebenza, kanye nezindawo ezine-vertical clearance encane ezivimbela ukumiswa kwemishini yokudonsa evamile. Imishini ibalulekile ezindaweni ezimaphakathi zejolofinyo, ezindaweni ezidala, kanye nasemithonjeni yezinhlaka lapho izindlela zokufaka izisekelo ezivamile zikhombisa izingozi ezimbi zemvelo noma zokwakha. Izikhungo zokudonsa ezihambayo zesimanje zifaka izinhlelo zokulawula ezithuthukisiwe, ukwenza kube lula ukulandela izinga lokudonsa ngesikhathi sangempela, nokuhlanganiswa nemishini yokugrout, ukuze kube nezisombululo ze-micropiling eziphelele kusuka ekuqaleni kokudonsa kuze kube sekucubungulweni kokugcina kwe-micropile nasekulinganeni umthwalo. Abaphathi bakhetha izikhungo zokudonsa ezihambayo uma izidingo zihambisana nezicelo zama-pile anedahometer encane, izikhala zidinga imishini yokwakha ehambayo, kanye nezoqondiso zezimali zisebenzela ukuhamba okusheshayo okunciphisa izidingo zabasebenzi kanye nokuphazamisa okuncane kwesurface uma kuqhathaniswa nezinye izindlela zokwakha nezindlela zokwakha ezijulile.
