Intengo yomshini oshayelwa umoya we-shotcrete 

Iumshini wokudubula oqhutshwa umoyaidonse ukunakwa okukhulu ezimbonini zokwakha nezezimayini ngenxa yokusebenza kahle kwayo nokuhlukahluka.

Le mishini isetshenziswa kakhulu ukufafaza ukhonkolo, futhi lo mshini we-pneumatic shotcrete usetshenziswa kumaphrojekthi ahlukahlukene, ikakhulukazi:

Ukumbiwa komhubhe:Isifutho sikakhonkolo esisebenza ngomoyakubalulekile ekuqiniseni izindonga zomhubhe nosilingi, ukunikeza ukwesekwa kwesakhiwo nokuqina.
Ukuzinza kweslope: Emayini nasekwakhiweni, umshini wokufafaza ukhonkolo usiza ukuvimbela ukubhidlika komhlaba ngokufafaza ukhonkolo emithambekeni eyimiqansa.
Izakhiwo ezingaphansi komhlaba: Umshini wokhonkolo wendiza yomoya ulungele izindawo eziwumngcingo lapho ukuxuba nokuthela kukakhonkolo okungokwesiko kungenakwenzeka.
Ukuvimbela amanzi: I-Shotcrete ivamise ukusetshenziselwa ukwakha izithiyo ezingangeni manzi emadamini nasezindaweni zokulondoloza amanzi.
Ukulungisa nokulungisa: Umshini we-shotcrete oshayelwa umoya usebenza kahle kakhulu ekulungiseni izakhiwo zikakhonkolo ezidinga ukuqina ngokushesha namandla aphezulu.

Umshini wokudubula oshayelwa umoya unezinzuzo eziningana:

Isivinini sohlelo lokusebenza: umoya ocindezelwe ungasetshenziswa ngokushesha, unciphise kakhulu isikhathi sephrojekthi.
I-Multifunctional: Umshini we-shotcrete oshayelwa umoya ungaphatha izingxube ezihlukahlukene ze-shotcrete, uzenze zifaneleke izinhlelo zokusebenza ezahlukene nezimo zemvelo.
Yehlisa izindleko zabasebenzi: Ukuzenzakalela kanye nokusebenza kalula kunciphisa isidingo senani elikhulu labasebenzi, ngaleyo ndlela kunciphisa izindleko zabasebenzi.
Ukuqinisa ukunamathela kwezinto: Isivinini somthelela omkhulu wokhonkolo ofuthwe sithuthukisa ukunamathela phezulu, ngaleyo ndlela kwenze uhlelo lokusebenza luqine.
Imfucuza encane: Uma kuqhathaniswa nendlela yokuthela yendabuko, ukusebenzisa umoya onembile kunciphisa udoti wezinto ezibonakalayo.

Okulandelayo yindaba yekhasimende lethu elisebenzisa umshini wethu we-pneumatic shotcrete ukwakha:

Iphrojekthi ye-Australia Metro Tunnel: Kulo mklamo omkhulu wengqalasizinda, umshini wokudubula oshayelwa umoya wasetshenziselwa ukuqinisa umhubhe ongaphansi komhlaba eMelbourne, owabonakala usiza ekugcineni ubuqotho besakhiwo nokusheshisa inqubekelaphambili yokwakha.

I-Hillside Stabilization, California: Umsebenzi wezimayini wasebenzisa umshini wokudubula umoya ukuze kuzinziswe umqansa, okwavimbela ngempumelelo ukudilika kwenhlabathi futhi kwaqinisekisa ukuphepha kwabasebenzi kanye nemishini.

Iphrojekthi yokubuyisela idamu laseSwitzerland: kusetshenziswa isifutho sikakhonkolo esisebenza emoyeni ukulungisa kanye nokuthuthukisa ukusebenza kwamadamu agugile ukuze angangeni manzi, okubonisa ukusebenza kwayo ezinhlelweni zengqalasizinda ezibalulekile.

Aumshini wokudubula we-pneumaticithuthukisa ukusetshenziswa kwe-shotcrete ezimbonini zokwakha nezimayini. Ukuze uthole ulwazi olwengeziwe mayelana nentengo yomshini we-shotcrete oshayelwa umoya kanye nokucaciswa kwawo, sicela usithinte.
