Amathangi Okuphosa

Iziphumo zokuhlanza zibalulekile ezisebenzini zokusebenza kwemicropiling, zisebenza njengemishini ethile yokuhambisa amanzi okumba nemixube ye-bentonite phakathi kwezinsiza zokumba ze-micropile. Le mishini ekhethekile igcina ukuzinza nokuhlanzeka kwemikhondo ngesikhathi sokufakwa kwemigqa encane, enamandla aphezulu ezindaweni ezixegayo nezimo zehlabathi ezinzima. Uhlelo lokuhlanza lusebenza ngokuhambisa umsebenzisi wokumba ngaphansi kwengcindezi elawulwayo ukuze uthumele endaweni yokumba, ususa kahle utshani nezinsika zehlabathi emikhondweni ngesikhathi esifanayo sakha isihlungi sokuvikela phezulu kwemikhondo. Le misebenzi eqhubekayo ye-sluur iyadingeka ukuze ivimbele ukuwa kwemikhondo, kulawulwe ukugeleza kwamanzi emhlabeni, nokuqinisekisa ukufakwa kahle kwezindawo ze-micropile nezinsika ze-grout. Izimpompo zokuhlanza zisebenza ngokususela kumgomo we-piston ewukuphehla, zifika nezinga eliqinile lokuhamba kwemithwalo elungele ububanzi bemikhondo obuphakathi nendawo obujwayelekile bezinhlelo zokusebenza ze-micropiling, ezivamise ukuba phakathi kuka-150mm kuya ku-300mm. Lezi ziphumo zisebenza ngezinhlobonhlobo ze-fluid zokumba ezifaka phakathi imifula esekelwe emanzini, ukuhlanganiswa komoya, nemixube ye-bentonite ethuthukisiwe nge-polymer, ngayinye yenziwe ngezimo ezithile zehlabathi nezimo ze-hydrogeological. Imigomo yokusebenza ivamise ukuba phakathi kuka-20 kuya ku-50 bar kuye ngokujula kwemikhondo, izici zokuphikisa zehlabathi, kanye nomklamo wezinsika. Ukuthembeka nezinga eliqinile lokukhishwa kweziphumo zokuhlanza kwenza kube kuhle ezindaweni zokwakha zasedolobheni, ezinhlelweni zokwengamela, ukugcinwa kwezemvelo, kanye nezimo zehlabathi ezinzima ezitholakala ekuthuthukisweni kwedolobha lapho izindlela zokufaka izinsika ezinkulu zendabuko zingasebenzi. Izicelo zeziphumo zokuhlanza zixhumene nezimo ezihlukahlukene ze-geotechnical kufaka phakathi i-micropiling ezindaweni ezithambile ze-clay, i-sandy silts, i-rock ethambile, kanye nezakhiwo eziphukile kakhulu. Lezi ziphumo ziveza ukubaluleka ekuwakheni izinsika ezikufuphi, lapho izakhiwo eziseduze nezinsiza zidinga ukungeneleka okuncane komhlaba kanye nolawulo oluqondile lokufakwa. Ukuvuselelwa kwamabhuloho, ukwakhiwa kwezakhiwo zomlando, ukuzinza kwemithambeka, nokuqiniswa kwesisekelo somhlaba osedolobheni kudinga kakhulu izinhlelo ze-micropiling ezineziphumo zokuhlanza ezithembekile. Ukuhlanganiswa kwezinhlelo zeziphumo zokuhlanza nezinsiza zokumba ze-rotary micropiling kuvumela abathengi ukuthi basebenze kahle ezindaweni ezihlakazekile ezinamathuba aphansi kanye nemigudu yendawo enzima. Ukukhethwa kahle kwesikhumba sokuphuma, izinga lokucindezela, kanye nekhono lokuphatha i-sluur kuhlobana ngqo nokusebenza kahle kokumba, ikhwalithi yemikhondo, kanye nokusebenza kahle kokugcina kwe-micropile kumakethe ye-B2B yokwakha izisekelo lapho ukuthembeka kwemishini kuhunyushwa ngokuhambisana nohlelo lweprojekthi kanye nokulawula izindleko.
