Summary: Kune abatshalizimali abaningi abahlose ukutshala imali kumshini wokwenza isihlabathi ngenxa yakho kokusheshisa komkhakha wezinto eziqoqwayo Eminyakeni yakamuva....

Khansi emakethe ephakathi kokukhula kwesihlabathi senjini, kubalulekile ukuqonda inqubo yokwenza isihlabathi. Njengoba sonke sazi,Inqubo yokukhiqiza isihlabathi sokwenziwa ihlanganisa inqubo yomile, inqubo engaphansi kokomisa isihlabathi kanye nenqubo ebushelelezi. Abasebenzisi bangakhiqiza izinhlobo ezahlukene zesihlabathi sokwenziwa ngokuya ngenqubo ezahlukene zokukhiqiza. Kepha kukhona abantu abaningi abangaziyo kahle lezi zinqubo ezintathu zokwenza isihlabathi, ngakho-ke ukukuphi okulandelayo sizokuchazela ngezindaba ezithinta lezi zinqubo.

Yini izinzuzo zokusebenzisa inqubo ebilayo ekwenzeni uthuli lwezihlabathi?

  • Umquketho wamanzi wesihlabathi esenziwe ngokukhiqiza okuyisiqalo ngokomkhuba oqeqeshwe ngokomkhuba uvamise ukuba ngaphansi kwe-2%, i-mortar yempahla noma i-mortar yomkhuba ingasetshenziswa ngqo.
  • Ukuqukethwe kwamanzi e-powder esiqeshini esiphelile kungalawulwa futhi kuphinde kusetshenziswe ngokusebenzisa isistimu eyodwa, futhi ukukhishwa kwe-dust kunganciphisa.
  • Indlela yokukhiqiza i-sand ngokomkhuba oqeqeshwe ngokomkhuba ingasindisa imithombo yamanzi hhayi kuphela amanzi (amanzi amancane noma angaphili), kodwa nezomthombo zemvelo ezinye.
  • Kubalulekile ukuthi abasebenzisi balawule izinhlobo eziningi zokusebenza ngokomkhuba oqeqeshwe ngokomkhuba, okungcono kakhulu ekusebenzeni ukuphathwa okuzenzakalelayo.
  • Umsebenzi wokukhiqiza umlotha omomile awuqondiswa yimiphumela yendawo, ixesha lobusika nobukhulu.

2. Kungani kusetshenziswa kancane inqubo yamanzi?

  • Okokuqala, inqubo yamanzi idinga amanzi amaningi.
  • Ukulinganiselwa kwamanzi emlotheni oqediwe kukhulu, ngakho kudingeka ukuba uhlanzwe.
  • I-modulus yokulinganisa umlotha oqediwe (nginqubo yamanzi) iphezulu, futhi kungase kube khona ukulahlekelwa komlotha omncane ngenqubo yokuhlambulula umlotha, okholela ekuphumeleni okuncane komlotha.
  • Kuzobe khona inani elikhulu le-silt nama-sewage ngenqubo yokukhiqiza umlotha wamanzi, okuyinkinga ngokuthi kuyadlayo ngokomzimba.
  • Izinga lokusebenza kwe-wet process akulona olujwayelekileyo ngesikhathi sezulu elomile, elomile noma elomkhathi.

3. Izici ze-semi-dry sand process

Ukuqhathaniswa nomsebenzi wokukhiqiza ithuli elimaningi lamanzi, ithuli eliphelile elenziwe nge-semi-dry alidingi ukugezwa, ngakho ukusetshenziswa kwamanzi kuyancipha kakhulu kunezindlela ezimanzi, umgogodla wegadi kanye nomquba wamanzi wezithuli eziphelile kungancipha ngokuphumelelayo.

Izindleko zokutshala imali enqubweni yokukhiqiza umquba wasimende uqhudelana kakhulu nezindleko zokukhiqiza umquba onamanzi, kodwa azikho ngaphezulu kwalezo zokukhiqiza umquba onamanzi amanzi. Ithamo lombombo wesitime ethintweni kanye nezindleko zokusebenza nakho kuyahluka phakathi kwalaba bobabili.

4. Ikhwalathi, elomile, elamanzi, i-semi-dry isandla, yini indlela yokukhetha?

(1) Khetha ngokuvumelana nezidingo zokukhiqiza

Okokuqala, abasebenzisi kufanele bathenge umshini wokwenza usizi ofanele ngokuhambisana nezinsiza zamanzi zasendaweni, izidingo zokuqukethwe kwephunga nokunemba komsebenzi wokomisa usizo, kanye nekhwalithi yezinto ezingavuthiwe.

Kunconywa ukuthi abasebenzisi bakhethe inqubo yokukhiqiza ithuli lomchwane omuncu kuqala; inqubo engenamanzi ingasetshenziswa njengenketho yesibili, kulandelwa inqubo emanzi.

(2) Izindleko zokukhiqiza

Ngokombono wecost yokutshalwa kwemishini, izindleko zokucubungula izihlabathi nobumba, kanye nobunzima bokuphatha ukukhiqizwa kwezitshalo zokwenza izihlabathi, inqubo eyomile usenalokhetho oluthandwayo, ilandelwa yinqubo engenamanzi kanye neyakugcina enamanzi.

Ngokwaziso lwezinyanga ezingama-30 ekwenzeni usimende, i-I-SBM ingangenele ubuchwepheshe obuphambili baphesheya komba futhi yadale uhlelo lwe-VU Tower-like Sand-making System. Isihlabathi esikhiqizwa uhlelo lwe-VU Sand-making System sihlala sinesekiso esihle kakhulu nangale kwalokho inqubo yokukhiqiza ayikhiphi i-sludge, amanzi angcolile noma uthuli, ihlangabezana ngokuphelele nezidingo zokuvikelwa kwemvelo. Sekwenzile izinzuzo ezinkulu namathuba okukhula kwezimboni ezihlukahlukene ezifana nesihlabathi, ukungxube okomile, ukuxuba kwamabhizinisi, amaphuli omtshingo, imikhiqizo yekhemikhali nezinye izinhlangano.
