Usonkontileka waseCanada i-Water Bblasting & Vacuum Services Inc. yeqe imikhawulo yokubhidlizwa kwe-hydraulic ngokusebenzisa iziteshi zamandla kagesi ngamanzi.
Ngaphezu kwamamayela angu-400 enyakatho ye-Winnipeg, iphrojekthi yokuphehla ugesi yase-Keeyask iyakhiwa eMfuleni i-Nelson ongezansi. Isiteshi sikagesi esiphehlwa ngamanzi esingu-695 MW esihlelelwe ukuthi siqedwe ngo-2021 sizoba umthombo wamandla avuselelekayo, sikhiqize isilinganiso esiyi-4,400 GWh ngonyaka. Amandla azokhiqizwa azohlanganiswa ohlelweni lukagesi lwe-Manitoba Hydro ukuze lusetshenziswe yi-Manitoba futhi luthunyelwe kwezinye izindawo. Kuyo yonke inqubo yokwakha, manje onyakeni wayo wesikhombisa, lo msebenzi uye wabhekana nezinselele eziningi eziqondene nendawo ethile.
Enye yezinselelo yenzeka ngo-2017, lapho amanzi epayipini elingama-intshi angu-24 endaweni yokungena amanzi eqaqeka futhi alimaza ugqinsi lukakhonkolo olungamamitha angu-8. Ukuze kuncishiswe umthelela kuyo yonke iphrojekthi, umphathi we-Keeyask wakhetha ukusebenzisa i-Hydrodemolition ukuze asuse ingxenye eyonakele. Lo msebenzi udinga usonkontileka ochwepheshile ongasebenzisa lonke ulwazi analo kanye nezinto zokusebenza ukuze anqobe izinselele zezemvelo nezokuthutha ngenkathi eletha imiphumela yekhwalithi ephezulu.
Ngokuthembela kubuchwepheshe be-Aquajet, kuhlanganiswe neminyaka yokuhlangenwe nakho kokudilizwa kwamanzi, inkampani yokuqhunyiswa kwamanzi kanye nesevisi ye-vacuum yephule imingcele yokudilizwa kwe-hydraulic, okuyenza ijule futhi ihlanzeke kunanoma iyiphi iphrojekthi yaseCanada kuze kube manje, iqedela i-4,944 cubic feet (140 cubic metres) Dismantle iphrojekthi ngesikhathi futhi ithole cishe u-80% wamanzi.

I-Canadian Industrial Cleaning Specialist Water Spray and Vacuum Services yaklonyeliswa ngenkontileka ngaphansi kohlelo olunganikezanga nje kuphela ukusebenza kahle kokuqeda ukuhlanza okungama-cubic feet angu-140 (140 cubic metres) ngesikhathi, kodwa futhi kutholakale cishe u-80% wamanzi. Ngobuchwepheshe be-Aquajet, buhlangene neminyaka yokuhlangenwe nakho, izinsiza zamanzi kanye nezinsiza ze-vacuum zicindezela imingcele ye-Hydrodemolition, iyenza ijule futhi ihlanzeke kunanoma iyiphi iphrojekthi yaseCanada kuze kube manje. Izinsiza zokufuthwa kwamanzi kanye ne-vacuum zaqala ukusebenza eminyakeni engaphezu kwengu-30 edlule, zihlinzeka ngemikhiqizo yokuhlanza yasendlini, kodwa lapho ibona isidingo sezisombululo ezintsha, ezigxile kumakhasimende kulezi zinhlelo zokusebenza, yanda ngokushesha ukuze inikeze izinhlangano zezimboni, zikamasipala, nezentengiso. izinsiza zokuhlanza. Njengoba izinsiza zokuhlanza izimboni kancane kancane ziba imakethe eyinhloko yenkampani, ukuqinisekisa ukuphepha kwabasebenzi endaweni eyandayo eyingozi kukhuthaza abaphathi ukuthi bahlole izinketho zamarobhothi.
Onyakeni wayo wama-33 isebenza, namuhla inkampani ye-water spray and vacuum iphethwe ngumongameli nomnikazi uLuc Laforge. Izisebenzi zayo zesikhathi esigcwele ezingama-58 zihlinzeka ngenani lezinkonzo zokuhlanza izimboni, zikamasipala, ezentengiselwano nezemvelo, ezisebenza ngokukhethekile ekuhlanzeni izimboni izicelo ezinkulu ekukhiqizeni, i-pulp nephepha, i-petrochemical, kanye nezindawo zobunjiniyela zomphakathi. Le nkampani iphinde ihlinzeke ngezinsiza zokudilizwa ngama-hydraulic kanye nezigayo zamanzi.
"Ukuphepha kwamalungu eqembu lethu bekulokhu kubaluleke kakhulu," kusho uLuc Laforge, uMongameli kanye noMnikazi we-Water Spray kanye ne-Vacuum Services. “Izicelo eziningi zokuhlanza izimboni zidinga amahora amaningi okusebenza ezindaweni ezivalekile kanye ne-PPE yobungcweti, njengezinhlelo zokungenisa umoya ngempoqo nezimpahla zokuvikela amakhemikhali. Sifuna ukusebenzisa noma yiliphi ithuba lapho singathumela khona imishini esikhundleni sabantu.”
Ukusebenzisa enye yemishini yabo ye-Aquajet-i-Aqua Cutter 410A-kukhulise ukusebenza kahle kwesifutho samanzi kanye nezinsiza ze-vacuum ngo-80%, kwafinyeza uhlelo oluvamile lokuhlanza ukukhuhla kusuka ohlelweni lwamahora angu-30 kuya emahoreni angu-5 nje. Ukuze kuhlangatshezwane nezinselele zokuhlanza amafekthri nezinye izinsiza zezimboni, i-Aquajet Systems USA yathenga imishini yamasekeni futhi yayilungisa endlini. Inkampani yasheshe yabona izinzuzo zokusebenza nabakhiqizi bemishini yokuqala ukuze kuthuthukiswe ukunemba, ukuphepha nokusebenza kahle. "Imishini yethu yakudala yaqinisekisa ukuphepha kweqembu futhi yaqeda umsebenzi, kodwa njengoba amafektri amaningi anciphisa ngenxa yokunakekelwa okujwayelekile ngenyanga efanayo, kwakudingeka sithole indlela yokwandisa ukusebenza kahle," kusho uLaforge.
Besebenzisa omunye wemishini yabo ye-Aquajet-i-Aqua Cutter 410A-Laforge yenyuse ukusebenza kahle ngo-80%, yafinyeza isicelo esivamile sokuhlanza i-scrubber sisuka ohlelweni lwamahora angu-30 saya emahoreni angu-5 kuphela.
Amandla nokusebenza kahle kwe-410A kanye nezinye izinto zokusebenza ze-Aquajet (kuhlanganise ne-710V) kwenza ukwandiswa kwesifutho samanzi kanye nezinsiza zokufutha ekuqhunyisweni kwe-hydraulic, ukugaya amanzi, nezinye izinhlelo zokusebenza, kukhulisa kakhulu uhla lwezinsizakalo zenkampani. Ngokuhamba kwesikhathi, idumela lenkampani lokuhlinzeka ngezixazululo zokudala kanye nemiphumela efika ngesikhathi, yekhwalithi ephezulu enomthelela omncane kwezemvelo kuye kwaphushela inkampani phambili embonini yokudilizwa kwe-hydraulic yaseCanada-futhi yavula umnyango wemiklamo eyinselele eyengeziwe. Lesi sithunzi senze izinsiza zokufuthwa kwamanzi kanye ne-vacuum zaba uhlu olufushane lwenkampani yendawo ephehla ugesi ngamanzi, ebidinga izixazululo ezikhethekile ukubhekana nomsebenzi wokubhidliza ukhonkolo ngephutha ongabambezela umsebenzi.
“Le iphrojekthi ethakazelisa kakhulu-eyokuqala yalolu hlobo,” kusho uMaurice Lavoie, umphathi jikelele wenkampani ye-water spray and vacuum kanye nomphathi wesizinda salo msebenzi. “Insika iwukhonkolo oqinile, ugqinsi olungamamitha angu-8, ububanzi bungamamitha angu-40, kanti indawo ephakeme ngamamitha angu-30 ukuphakama. Ingxenye yesakhiwo idinga ukudilizwa futhi iphinde ithululwe. Akekho umuntu e-Canada—bayingcosana kakhulu emhlabeni—abasebenzisa i-Hydrodemolition ukudiliza ugqinsi olumamitha angu-8. Ukhonkolo. Kodwa lesi kumane kuyisiqalo sobunzima nezinselelo zalo msebenzi.”
Indawo yokwakha yayicishe ibe ngamamayela angu-2,500 (amakhilomitha angu-4,000) ukusuka endlunkulu yosonkontileka e-Edmundston, New Brunswick, kanye namamayela angu-450 (amakhilomitha angu-725) enyakatho yeWinnipeg, eManitoba. Noma yisiphi isisombululo esihlongozwayo sidinga ukucatshangelwa ngokucophelela kwamalungelo okufinyelela anomkhawulo. Nakuba abaphathi bephrojekthi bengahlinzeka ngamanzi, ugesi, noma ezinye izinto zokwakha ezivamile, ukuthola imishini ekhethekile noma izingxenye ezishintshayo kuyinselele edla isikhathi. Osonkontileka badinga okokusebenza okuthembekile namabhokisi amathuluzi agcwele kahle ukuze balinganisele noma isiphi isikhathi sokuphumula esingadingekile.
“Lo msebenzi unezinselelo eziningi okufanele uzinqobe,” kusho uLavoy. “Uma kunenkinga, indawo ekude iyasivimbela ukuthi singene kochwepheshe noma ama-spare parts. Okubaluleke kakhulu ukuthi sizobhekana namazinga okushisa angaphansi kwe-zero, angehla kalula ngaphansi kuka-40. Kufanele ube neqembu elikhulu lakho kanye nemishini yakho. Amabhidi angathunyelwa ngokuzethemba kuphela.”
Ukulawulwa okuqinile kwezemvelo nakho kukhawulela izinketho zezicelo zosonkontileka. Abalingani bephrojekthi eyaziwa ngokuthi yi-Keeyask Hydropower Limited Partnership-kuhlanganise nabomdabu abane baseManitoba kanye nokuvikelwa kwemvelo okwenziwe nge-Manitoba Hydropower okuyisisekelo sayo yonke iphrojekthi. Ngakho-ke, nakuba isithangami sokuqala saqoka ukubhidlizwa kwamanzi njengenqubo eyamukelekayo, usonkontileka kwakudingeka aqinisekise ukuthi wonke amanzi angcolile aqoqwa futhi ahlanzwa ngendlela efanele.
Uhlelo lokuhlunga amanzi lwe-EcoClear lwenza izinsiza zokufuthwa kwamanzi kanye ne-vacuum zinikeze abaphathi bephrojekthi isisombululo soguquko-isixazululo esithembisa ukukhiqiza okuphezulu ngenkathi kunciphisa ukusetshenziswa kwezinsiza nokuvikela imvelo. I-Aquajet Systems USA "Kungakhathaliseki ukuthi sisebenzisa yiphi ubuchwepheshe, kufanele siqinisekise ukuthi akukho nomthelela omubi endaweni ezungezile," kusho uLavoy. “Enkampanini yethu, ukukhawulela umthelela kwezemvelo kuhlale kuyingxenye ebalulekile yanoma iyiphi iphrojekthi, kodwa uma kuhlanganiswa nendawo ekude yephrojekthi, siyazi ukuthi kuzoba nezinselelo ezengeziwe. Ngokusho kwesayithi langaphambilini le-Labrador Muskrat Falls Power Generation Project Kusukela kokuhlangenwe nakho okungenhla, siyazi ukuthi ukuthutha amanzi nokuphuma kuyisinqumo, kodwa kubiza futhi kungasebenzi kahle. Ukwelapha amanzi esizeni nokuwasebenzisa kabusha kuyisixazululo esiyonga kakhulu futhi esinobungani nemvelo. Nge-Aquajet EcoClear, sesivele sinesixazululo esifanele. Umshini wokuwenza usebenze.”
Uhlelo lokuhlunga amanzi lwe-EcoClear, oluhlangene nolwazi oluningi kanye nokusetshenziswa kochwepheshe bezinkampani ze-water spray kanye ne-vacuum service, lwenza osonkontileka bakwazi ukunikeza abaphathi bephrojekthi isixazululo esishintshashintshayo esithembisa ukukhiqiza okuphezulu ngenkathi kunciphisa ukusetshenziswa kwezinsiza nokuvikela isisombululo semvelo.
Inkampani ye-water spray kanye ne-vacuum service yathenga uhlelo lwe-EcoClear ngo-2017 njengendlela ephumelela kakhulu futhi engabizi kakhulu yokusebenzisa amaloli e-vacuum ukuthutha amanzi angcolile ukuze ahlanzwe ngaphandle kwendawo. Uhlelo lunganciphisa i-pH yamanzi futhi lunciphise ukungcola ukuze luvumele ukukhululwa okuphephile kubuyele endaweni. Ingahamba ifike ku-88gpm, noma cishe amalitha angama-5,238 (ama-cubic metres angama-20) ngehora.
Ngokungeziwe kusistimu ye-Aquajet's EcoClear kanye ne-710V, isifutho samanzi nesevisi ye-vacuum iphinda isebenzisa i-boom kanye nengxenye yombhoshongo eyengeziwe ukuze kwandiswe ububanzi bokusebenza berobhothi le-Hydrodemolition libe ngamafidi angu-40. Isifutho samanzi kanye nezinsizakalo ze-vacuum zincoma ukusebenzisa i-EcoClear njengengxenye yesistimu ye-loop evaliwe ukuze ujikeleze amanzi abuyele ku-Aqua Cutter 710V yayo. Lokhu kuzoba okokuqala kwenkampani ukusebenzisa i-EcoClear ukuthola amanzi ngenani elikhulu kangaka, kodwa uLavoie nethimba lakhe bakholelwa ukuthi i-EcoClear ne-710V kuzoba inhlanganisela ephelele yezinhlelo zokusebenza eziyinselele. "Le phrojekthi ihlole abasebenzi bethu kanye nemishini," kusho uLavoy. "Kube neziqalo eziningi, kodwa siyazi ukuthi sinolwazi nokwesekwa kweqembu le-Aquajet ukuguqula izinhlelo zethu zisuke emcabangweni ziye eqinisweni."
Isifutho samanzi kanye nesevisi ye-vacuum yafika endaweni yokwakha ngo-March 2018. Izinga lokushisa elijwayelekile ngu--20º F (-29º Celsius), ngezinye izikhathi liphansi -40º F (-40º Celsius), ngakho-ke isistimu yokuqongelela kanye ne-heater kufanele isethwe. ukuze unikeze indawo yokukhosela eduze kwendawo yokubhidliza futhi ugcine iphampu isebenza. Ngaphezu kwesistimu ye-EcoClear kanye ne-710V, usonkontileka uphinde wasebenzisa i-boom kanye nesigaba sombhoshongo eyengeziwe ukuze akhulise ububanzi bokusebenza berobhothi le-Hydrodemolition ukusuka kumafidi angu-23 ukuya kwangu-40. Ikhithi yokunweba iphinde ivumele osonkontileka ukuthi benze ukusikeka okungamamitha ayi-12 ububanzi. Lezi zithuthukisi zinciphisa kakhulu isikhathi sokuphumula esidingekayo ukuze kumiswe kabusha njalo. Ngaphezu kwalokho, izinsiza zokufuthwa kwamanzi kanye ne-vacuum zasebenzisa izingxenye ezengeziwe zesibhamu sokufutha ukuze kwandiswe ukusebenza kahle futhi zivumele ukujula okungamamitha ayisishiyagalombili okudingekayo kuphrojekthi.
Isifutho samanzi kanye nesevisi ye-vacuum idala iluphu evaliwe ngohlelo lwe-EcoClear kanye namathangi amabili angamalitha angu-21,000 ukuze aphakele amanzi ku-Aqua Cutter 710V. Phakathi nalo msebenzi, i-EcoClear icubungule amanzi angaphezu kwezigidi eziyi-1.3. I-Aquajet Systems USA
U-Steve Ouellette ungumqondisi omkhulu wenkampani ye-water spray and vacuum service, obhekene nesistimu ye-loop evaliwe yamathangi amabili angama-21,000 ahlinzeka ngamanzi ku-Aqua Cutter 710V. Amanzi angcolile aqondiswe endaweni ephansi bese empontshelwa ku-EcoClear. Ngemva kokuba amanzi esecutshunguliwe, aphindiselwa ethangini lokugcina ukuze aphinde asetshenziswe. Phakathi neshifu yamahora angu-12, isifutho samanzi kanye nensizakalo yevacuum isuse isilinganiso sama-cubic feet angu-141 (4 cubic metres) kakhonkolo futhi yasebenzisa cishe amalitha angu-40,000 amanzi. Phakathi kwazo, cishe u-20% wamanzi ulahlekile ngenxa yokuhwamuka nokumuncwa kukhonkolo ngesikhathi senqubo ye-Hydrodemolition. Nokho, isifutho samanzi kanye nezinsiza ze-vacuum zingasebenzisa uhlelo lwe-EcoClear ukuze ziqoqe futhi zigaywe kabusha ama-80% asele (amalitha angu-32,000). Phakathi nawo wonke umsebenzi, i-EcoClear icubungule amanzi angaphezu kwezigidi ezingu-1.3.
Ithimba le-spray yamanzi kanye ne-vacuum lisebenza i-Aqua Cutter cishe isikhathi sonke samahora angu-12 nsuku zonke, lisebenza engxenyeni engu-12-foot-wide ukuze libhidlize kancane umgodi wamafidi angu-30 ukuphakama. I-Aquajet Systems' American water spray and vacuum service kanye nabaphathi bephrojekthi bahlanganisa ukuhlakazwa ohlelweni oluyinkimbinkimbi lwawo wonke umsebenzi, baphothula umsebenzi esigabeni esingaphezu kwamasonto amabili. U-Lavoie nethimba lakhe basebenzisa i-Aqua Cutter cishe isikhathi sonke samahora angu-12 nsuku zonke, besebenza engxenyeni engamamitha angu-12 ububanzi ukuze babhidlize ngokuphelele udonga. Isisebenzi esihlukene sizofika ebusuku sizosusa izinsimbi nemfucumfucu. Lolu hlelo lwaphindwa cishe izinsuku ezingama-41 zokuqhuma kanye nengqikithi yezinsuku ezingama-53 zokuqhunyiswa kwendawo.
I-water spray and vacuum service yaqeda ukubhidlizwa kwezindlu ngoMeyi 2018. Ngenxa yenguquko nobungcweti bokwenziwa kohlelo kanye nemishini emisha, umsebenzi wokubhidliza awuzange uphazamise lonke uhlelo lwephrojekthi. "Lolu hlobo lwephrojekthi luba kanye kuphela empilweni," kusho uLaforge. "Sibonga ithimba elizinikele elinolwazi futhi elinesibindi sokusebenzisa imishini emisha engenakwenzeka, sikwazile ukuthola isisombululo esiyingqayizivele esisivumele ukuthi sidlule imingcele ye-Hydrodemolition futhi sibe yingxenye yokwakhiwa okubaluleke kangaka."
Nakuba izinsiza zokufuthwa kwamanzi ne-vacuum zilindele iphrojekthi efanayo elandelayo, u-Laforge nethimba lakhe elicokeme bahlela ukuqhubeka nokwandisa ulwazi lwabo lokuqhunyiswa kwe-hydraulic ngokusebenzisa ubuchwepheshe obusha be-Aquajet kanye nemishini ephambili.
