I-CHUANGROGN Pipe eDhaka DWASA Project
Isizinda Sephrojekthi
Ukuthuthukiswa kwengqalasizinda yasemadolobheni eBangladesh akuhambisananga nokukhula kwedolobha okusheshayo. Ukuhlinzekwa kwamanzi okuphuza enhloko-dolobha yaseBangladesh iDhaka kube yinselele enkulu.
Iphrojekthi Yokuthuthukisa Inethiwekhi Yokuphakelwa Kwamanzi eDhaka (i-DWSNIP) ihlose ukuthuthukisa ukuhlinzekwa kwamanzi azinzile, athembekile, futhi amelana nesimo sezulu edolobheni laseDhaka. Izothuthukisa izinzuzo zokusebenza kahle kwenethiwekhi yokusabalalisa ezitholakale ngaphansi kwamaphrojekthi amabili angaphambilini axhaswe yiBhange Lentuthuko lase-Asia (i-ADB) eDhaka Water Supply and Sewerage Authority (i-DWASA) ukuze kuthuthukiswe ukulethwa kwezinsizakalo kanye nokwakhiwa kwamakhono.
Imisebenzi yokwakha
Imisebenzi yokwakha kule phrojekthi encane ihlanganisa kakhulu ukufakwa kwamapayipi okuhambisa amanzi kusukela kububanzi obusukela ku-75 mm kuya ku-400 mm.
Amapayipi e-HDPE aqinile kakhulu, ahlala isikhathi eside, futhi amelana nokuqhekeka kokucindezeleka futhi awathinteki kakhulu ekungcoleni okuningi kwamakhemikhali kanye nokwezinto eziphilayo. Izici zepayipi zazisho ukuthi idinga ukulungiswa okuncane kakhulu kunezinye izinto zokufaka amapayipi nokuqinisekisa amandla okugeleza aphezulu kuyo yonke impilo yayo yokusebenza.
Isixazululo sesistimu ye-ChuangRong sasihlanganisa amapayipi, ama-couplers e-electrofusion, imishini ye-electrofusion, ukwesekwa kobunjiniyela, amathuluzi okufaka akhethekile, kanye nokuqeqeshwa.
Le misebenzi izofaka phakathi ukumba okuqondile kokubeka amapayipi emigwaqweni, ukubeka amapayipi emseleni, ukuhlanganisa, ukuhlola amanzi kanye nokugcwalisa kabusha ngenhlabathi evubukuliwe. Umgwaqo Omkhulu waseDholaikhal, Umgwaqo Omkhulu waseBegum Gonj Lane, Umgwaqo Omkhulu waseDoyagong, Umgwaqo Omkhulu waseKaptan Bazar To Gulistan, Umgwaqo Omkhulu waseWari, Umgwaqo waseBahadur shahpark, Umgwaqo omusha waseGendaria, Umgwaqo iShahid Faruk njll. yimigwaqo emikhulu (ububanzi > 4m) endaweni yephrojekthi encane. Eminye imigwaqo ebalulekile yangaphakathi (ububanzi 2-4 m).
