INorfolk County sisixeko esiseOntario, eCanada. Yadityaniswa yasisixeko esinye ngo-2001 esinabemi abangaphezu kwama-60,000. INorfolk ikwiikhilomitha ezingama-56 (iikhilomitha ezingama-35) kumzantsi-ntshona weHamilton kunye neekhilomitha ezingama-97 (iikhilomitha ezingama-60) kumzantsi-mpuma weLondon.
Le dolophu isandula kudibana nempumelelo enkulu kwi-12-intshi ye-ductile yentsimbi yamanzi engundoqo. Oku kuphela kwesibonelelo esivela kuluntu lwasePort Rondon ukuya kuluntu lwaseSt. Iqela likrokrela ukuba ukuvuza kulo mgca kubangelwa yi-pitting, eyona nto ibangela ukusilela kwemibhobho yentsimbi. Ngethuba lexesha lokugcinwa, abasebenzi bamanzi babonise ukuba i-bottom of the ductile iron main water yayibonakaliswe kwaye i-corrored.
Kukho ezinye iindawo zokuhlala eNorfolk, ezifunyenwe kwiindawo zamaqula ngezi ngcingo zothumelo lwemibhobho. Ezi sayithi zikwasemngciphekweni wokuhlaselwa ngenxa yokutya okukodwa kunye nokungabikho kokuphindaphinda. "Utshilo uJeff Demeulemeester, ingcali yobunjineli eqinisekisiweyo yaseNorfolk kunye nomphathi weprojekthi.
Isicwangciso senkunzi seminyaka eli-10 seNorfolk siyinxalenye yesicwangciso sozinzo lwemali sexesha elide kwaye sigxininisa ukubaluleka kokuqinisekisa ngokubaluleka, iiprojekthi eziqinisekisiweyo nezifikelelekayo. Ubume bangoku bemibhobho yamanzi kufuneka iqondwe ukuqinisekisa ukugcinwa okusebenzayo kokuthintela.
Ingingqi ingenise isicelo seziphakamiso zokuvavanya imeko yemibhobho yamanzi. Emva kwemijikelo emininzi yovavanyo kunye neengxoxo, itekhnoloji yovavanyo lwemeko ye-Echologics ePulse engeyiyo invasive ebonelelwe nguMueller yakhethwa ukumisela imeko ekhoyo yesakhiwo kunye nokufumana nakuphi na ukuvuza okukhoyo kunye nokungaqhelekanga.
Kule projekthi, i-Echologics ivavanye malunga neekhilomitha ezi-6.9 (iikhilomitha ezi-4.3) zentloko yentsimbi yentsimbi ehamba kakhulu kwindlela engaphambili. I-Norfolk yakhetha le nxalenye yombhobho ngenxa yokunqongophala kwayo kunye nembali yokuphazamiseka kwangaphambili. Ekubeni ukusilela kwalo mgca kusenokuba nempembelelo ebalulekileyo kubahlali baseNorfolk, uvavanyo lovavanyo lwemeko lwenziwa ukuze kubonwe ukuba ngaba nayiphi na imimandla esecaleni komgca ifumene ukuthotywa okumandla. Ngokusekwe kwiziphumo zovavanyo, iNkampani yobuNjineli be-AECOM icebisa isicwangciso sohlaziyo sombhobho olandelayo njengoko kufuneka.
Umfanekiso 3. Ichaza umthi wesigqibo esilungiselelweyo ukukhetha indlela yohlaziyo (ulungiso kunye nokutshintshwa) kumacandelo emibhobho angama-54 esekelwe kwiZiphumo zoHlolo lwe-ePulse..jpeg
Itekhnoloji ye-ePulse iphunyezwa ngokudibanisa i-acoustic sensors ezimbini kwindawo nganye ekhoyo yoqhagamshelwano (efana ne-fire hydrant, i-valve okanye ukudibana ngokuthe ngqo nodonga lombhobho). Amaza omsindo aphenjelelwa kumbhobho, kwaye isantya sokusasaza samaza esandi silinganiswa phakathi kwezivamvo ezimbini zamaza esandi.
Isantya sokusasazwa kwamaza esandi sixhomekeke kwimeko yodonga lombhobho. Emva kokuba umsebenzi owenziwe kwisiza ugqityiwe, isantya sesandi sidityaniswe nolunye ulwazi oluqokelelwe kwisiza (kubandakanywa umgama kunye nobushushu bamanzi), kwaye emva koko i-algorithm yobunikazi obuphezulu isetyenziselwa ukumisela umndilili oseleyo wodonga lwecandelo ngalinye.
Ezi ziphumo zitolikwa ngokohlobo lwamacandelo amathathu “olungileyo”, “ophakathi” kunye “nobuhlwempu”. Umyinge womonakalo eludongeni ongaphantsi kwe-10% uboniswa njengento elungileyo; ipesenti yomonakalo eludongeni ukusuka kwi-10% ukuya kwi-30% ibonakaliswe njengephakathi; ipesenti engaphezu kwama-30% ihlelwa “njengembi”.
Umphathi weprojekthi ye-AECOM uKhalid Kaddoura uthe: "Isiphumo ngasinye se-ePulse simele imeko ephakathi kwixesha elithile phakathi kweendawo ezimbini zokudityaniswa kwezinzwa." Imibhobho etshintshiweyo ibekwe ngokwendawo. Ngale njongo, iziphumo ze-ePulse zintle kakhulu. ”
Umzobo 2: Inzwa idityaniswe ngombane kwivalve kwaye intambo iqhagamshelwe kwi-transmitter yovavanyo lwemeko ye-acoustic.
Inxalenye yesibini yeprojekthi ifuna ukuba uphando lokuvuza kunye neemeko ezingaqhelekanga zigqitywe ngexesha elifanayo novavanyo lwemeko. Olu luncedo lokusasaza i-ePulse kuba i-acoustic correlator efanayo inokusetyenziselwa ukwenza uvavanyo kunye nokufumanisa ukuvuza ngaxeshanye.
Emva kwexesha lovavanyo lweentsuku ezili-12, iziphumo ze-ePulse zibonise ukuba i-12 yamacandelo angama-54 wothungelwano ayekwimeko embi, kunye nelahleko yobunzima bodonga obungaphezulu kwe-30%. Ukongezelela, kukho amacandelo angama-30 kwimeko ephakathi, kwaye ubukhulu bodonga bokuqala bulahlekelwe yi-10% ukuya kwi-30%. Amanye amacandelo enethiwekhi ye-11 akwimeko efanelekileyo, ilahleko ye-original yobunzima bodonga ingaphantsi kwe-10%, kwaye inxalenye eseleyo yenethiwekhi ayikwazi ukusasaza iziphumo.
Akukho kuvuza kufunyenwe ngexesha lophando. Nangona kunjalo, indawo yomdla (POI) ichongiwe. Ilogo ye-POI ibonisa ukuba ezinye (kodwa hayi zonke) zekhrayitheriya yeziphumo zovavanyo ezivuzayo zifunyenwe. Uphando lwesibini kamva luqinisekisile ukuba ingxolo yokuvuza isuka kwivalve eqhelekileyo yokusebenza yoxinzelelo kwimitha kakuhle.
UDemeulemeester uthe: “Siyavuya kakhulu kukuba le projekthi isinike iinkcukacha esizidingayo ukuze sibeke phambili kwaye simisele ishedyuli yokutshintsha efundileyo esekelwe kubunzima obushiyekileyo bodonga lombhobho wamanzi.” “Ngaphezu koko, iindleko zovavanyo zithathwa njengezingabalulekanga kuba zibonelele ngeNqila yaseNorfolk ngedatha eyimfuneko yokubeka phambili ukutshintshwa kothungelwano lwethu oluphambili ngokubaluleka kwisicwangciso senkunzi yeminyaka eli-10. Ngokusekwe kolona luhlu lweshedyuli lokutshintsha "olona luphambili lubaluleke kakhulu", siye sakwazi ukugcina ixesha kunye nesicwangciso semali esifunekayo esivumelanayo.
Ngokusekwe kwiziphumo eziqokelelwe liqela lendawo ye-Echologics, i-AECOM iphuhlise umthi wesigqibo sohlaziyo olulungiselelweyo kunye noqikelelo lweendleko zohlahlo lwabiwo-mali lweenkqubo zohlaziyo. Idityaniswe neziphumo zokuhlolwa kwe-ePulse, umthi wesigqibo usekwe kwezi ntlobo zintathu zeemeko zilandelayo: ezilungileyo, eziphakathi kunye nezihluphekileyo.
Kwiindidi ezimbini zokuqala ezilungileyo kunye neziphakathi, kuyacetyiswa ukuba kuvavanywe ukusebenza koxinzelelo lwe-hydraulic kwimibhobho yamanzi. Ukuba iwela phakathi koluhlu olwamkelekileyo, uvavanyo olongezelelweyo luya kwenziwa ukujonga iimpawu zamanzi. Ukuba umgangatho wamanzi awuhambelani nemigangatho yendawo, kucetyiswa ungenelelo lokubuyisela kwisimo sangaphambili.
Ngakolunye uhlangothi, ukuba ukusebenza kwe-hydraulic yombhobho wamanzi akwamkelekanga okanye kunqunywe ukuba kukwimeko embi, kucetyiswa ukuba kuthathelwe indawo amandla ombane, ukuba kufuneka amandla angaphezulu kwe-hydraulic. Ukuba umthamo we-hydraulic wanele, qwalasela ukuhlaziywa kwimeko yeteknoloji ngecala ngokusekelwe kuhlalutyo lweendleko kunye nendawo yomgangatho wesakhiwo.
Emva kokuba iprojekthi igqityiwe, iNqila yaseNorfolk iceba ukubuyisela amacandelo emibhobho akwimeko embi kwaye igqiba ekubeni kubuyiselwe amacandelo angakumbi emibhobho kwisicwangciso sayo senkunzi yeminyaka eli-10.
PE, Alain Lalonde ngumphathi wengingqi ye-Echologics e-Mueller, eCanada. Ungaqhagamshelana noLalonde ngokusebenzisa [uKhuseleko lwe-imeyile].
Abasebenzi be-"Water and Waste Digest" bamema iingcali zeshishini ukuba zityumbe ezona projekthi zibalaseleyo nezintsha zamanzi kunye namanzi amdaka abacinga ukuba zamkelwa "kwiSikhokelo soNyaka seReferensi." Kwiinyanga ezili-18 ezidlulileyo, zonke iiprojekthi kufuneka zibekwisigaba soyilo okanye sokwakha.
