Uyini Umehluko Phakathi Kokusetshenziswa Kwe-Wet-Mix kanye Ne-Dry-Mix?

Umehluko phakathi kokusetshenziswa kwengxube emanzi kanye nengxube eyomile usendleleni yokulungisa nokusebenzisa ingxube yekhonkrithi noma yesamente. Lezi zindlela ezimbili zinezici ezihlukile, izinzuzo, kanye nezinhlelo zokusebenza ekwakheni. Nasi isiqhathaniso:

1. Izicelo Zokuxuba Okumanzi:

Ukulungiselela:

• Ezisetshenzisweni zokuxuba okumanzi, zonke izithako zekhonkrithi noma ze-mortar, okuhlanganisa usimende, ama-aggregates, amanzi, kanye nezithasiselo, zixutshwa ndawonye esitshalweni esiphakathi noma esixubeni esisendaweni.
• Ingxube ephumayo ithuthwa iye endaweni yokwakha ngamaloli noma amaphampu ekhonkrithi.

Isicelo:

• Ikhonkrithi noma udaka oluxutshwe ngamanzi lufakwa ngokushesha ngemva kokuxuba, ngenkathi lusesesesimweni soketshezi noma sepulasitiki.
• Ithululwa noma ipompelwe ngqo endaweni elungisiwe bese isakazwa, ilinganiswe, bese iqedwa kusetshenziswa amathuluzi namasu ahlukahlukene.
• Izinhlelo zokuxuba amanzi zivame ukusetshenziswa kumaphrojekthi amakhulu njengezisekelo, ama-slab, amakholomu, imishayo, kanye nezakhi zesakhiwo.

Izinzuzo:

• Ukusebenza kahle kakhulu: Ikhonkrithi noma udoti oxutshwe ngamanzi kulula ukuwuphatha nokuwubeka ngenxa yokunamathelana kwawo koketshezi, okuvumela ukuqina nokuqina okungcono.
• Ukwakhiwa okusheshayo: Ukusetshenziswa kokuxubana ngamanzi kuvumela ukufakwa nokuqedwa kwekhonkrithi ngokushesha, okuholela ekuthuthukisweni okusheshayo kokwakhiwa.
• Ukulawula okukhulu izakhiwo zokuxuba: Ukuhlanganisa zonke izithako ndawonye kuvumela ukulawula okunembile isilinganiso samanzi nosimende, amandla, kanye nokuvumelana kwengxube yekhonkrithi.

Okubi:

• Kudinga abasebenzi abanamakhono: Ukubekwa kahle kanye nokuqedwa kahle kwekhonkrithi exutshwe ngamanzi kudinga abasebenzi abanamakhono kanye nesipiliyoni ukuze kufezwe imiphumela efiselekayo.
• Isikhathi esilinganiselwe sokuhamba: Uma ukhonkolo usuxubile, omanzi kumele ubekwe ngaphakathi kwesikhathi esithile (ngokuvamile okubizwa ngokuthi “impilo yebhodwe”) ngaphambi kokuba uqale ukunamathela nokuqina.
• Kungenzeka ukuthi kube nokuhlukaniswa: Ukuphathwa kabi noma ukuthuthwa kwekhonkrithi emanzi kungaholela ekuhlukanisweni kwama-aggregate, okuthinta ukufana kanye namandla omkhiqizo wokugcina.

2. Izicelo Zokuxuba Omile:

Ukulungiselela:

• Ezisetshenzisweni zokuxuba okomile, izithako ezomile zekhonkrithi noma ze-mortar, njengesamente, isihlabathi, ama-aggregates, kanye nezithasiselo, zixutshwa kusengaphambili bese zifakwa ezikhwameni noma ezitsheni ezinkulu esitshalweni sokukhiqiza.
• Amanzi ayengezwa engxubeni eyomile endaweni yokwakha, kungaba ngesandla noma kusetshenziswa imishini yokuxuba, ukuze kusebenze umswakama futhi kwakhiwe ingxube esebenzisekayo.

Isicelo:

• Ukhonkolo noma udaka oluxutshwe okomile lufakwa ngemva kokufaka amanzi, ngokuvamile kusetshenziswa umshini wokuxuba noma imishini yokuxuba ukuze kufezwe ukuvumelana okufiselekayo.
• Bese ibekwa, isakazwe, bese iqedwa endaweni elungisiwe kusetshenziswa amathuluzi namasu afanele.
• Izicelo zokuxuba okomile zivame ukusetshenziswa kumaphrojekthi amancane, ukulungiswa, ukuvuselelwa, kanye nezicelo lapho ukufinyelela noma isikhathi sikhawulela ukusetshenziswa kwekhonkrithi emanzi.

Izinzuzo:

• Kulula futhi kuyaguquguquka: Ikhonkrithi noma udoti oxutshwe okomile ungagcinwa, uthuthwe, futhi usetshenziswe endaweni lapho kudingeka khona, okunikeza ukuguquguquka okukhulu kanye nokulula.
• Ukunciphisa imfucuza: Izinhlelo zokuxuba okomile zinciphisa imfucuza ngokuvumela ukulawula okunembile inani lezinto ezisetshenziswa kuphrojekthi ngayinye, kunciphisa izinto ezisele neziningi.
• Ukusebenza okuthuthukisiwe ezimweni ezimbi: Ikhonkrithi exutshwe ngomshini owomile ingaphathwa kalula futhi isetshenziswe ezimweni zezulu ezimbi noma ezindaweni ezikude lapho ukufinyelela kwamanzi noma amaloli ekhonkrithi kungase kuncishiswe khona.

Okubi:

• Ukusebenza okuphansi: Ikhonkrithi noma udoti oxutshwe ngomshini owomile kungadinga umzamo omkhulu ukuxuba nokubeka uma kuqhathaniswa nokusetshenziswa kokuxuba okumanzi, ikakhulukazi ekufezeni ukusebenza okwanele kanye nokuvumelana.
• Isikhathi eside sokwakha: Ukufakwa kokuxuba okomile kungathatha isikhathi eside ukuqeda ngenxa yesinyathelo esengeziwe sokuxuba amanzi nezithako ezomile endaweni.
• Ukusetshenziswa okulinganiselwe kwezinto zokwakha: Ikhonkrithi exutshwe okomile ingase ingafaneleki ezintweni ezinkulu zokwakha ezidinga ukusebenza kahle kakhulu kanye nokubekwa okunembile.

Ngamafuphi, izinhlelo zokusebenza ezixubene ngamanzi kanye nezomile zinikeza izinzuzo ezihlukile futhi zisetshenziswa ezimweni ezahlukene zokwakha ngokusekelwe ezidingweni zephrojekthi, izimo zendawo, kanye nokucatshangelwa kwempahla. Izinhlelo zokusebenza ezixubene ngamanzi ziyathandwa kumaphrojekthi amakhulu adinga ukusebenza kahle kakhulu kanye nokubekwa ngokushesha, kuyilapho izinhlelo zokusebenza ezixubene ngamanzi zinikeza ukulula, ukuguquguquka, kanye nokunciphisa imfucuza yamaphrojekthi amancane, ukulungiswa, kanye nokuvuselelwa.
