CHUANGROGN Piping in Dhaka DWASA Project
Ingemuva lephrojekthi
Ukuthuthukiswa kwengqalasizinda yasemadolobheni e-Bangladesh akuzange kuhambisane nokukhula ngokushesha kwamadolobha. Ukuhlinzekwa kwamanzi okuphuza enhloko-dolobha yaseBangladesh iDhaka kube inselele kakhulu.
I-Dhaka Water Supply Network Improvement Project (DWSNIP) ihlose ukuthuthukisa ukuhlinzekwa kwamanzi okusimeme, okuthembekile, nokukwazi ukumelana nesimo sezulu edolobheni laseDhaka. Izothuthukisa impumelelo yenethiwekhi yokusatshalaliswa ezuzwe ngaphansi kwamaphrojekthi amabili adlule e-Asian Development Bank (ADB) exhase ngezimali iDhaka Water Supply and Sewerage Authority (DWASA) ukuze kwenziwe ngcono ukulethwa kwezinsiza kanye nokwakhiwa kwamandla.
Imisebenzi yokwakha
Imisebenzi yomphakathi kuphrojekthi encane ikakhulukazi ihlanganisa ukulayishwa kwamapayipi okuhambisa amanzi ukusuka kububanzi obusuka ku-75 mm kuya ku-400 mm.
Amapayipi e-HDPE anokuqina okuphakeme, ukuphila isikhathi eside, kanye nokumelana nokuqhekeka kwengcindezi futhi asondelene nokungenwa ukonakala okuningi kwamakhemikhali nemvelo. Izici zepayipi zazisho ukudinga ukulungiswa okuncane kakhulu kunezinye izinto zamapayipi kanye nokuqinisekisa umthamo wokugeleza okuphezulu kuyo yonke impilo yayo yesevisi.
Isixazululo sohlelo lweChuangRong sasihlanganisa amapayipi, ama-electrofusion couplers, imishini ye-electrofusion, ukwesekwa kobunjiniyela, amathuluzi okufakwa okukhethekile, nokuqeqeshwa.
Le misebenzi izobandakanya ukumba ngomugqa wokufaka amapayipi emigwaqweni, ukufaka amapayipi emseleni, ukuhlanganisa, ukuhlola amanzi kanye nokugcwalisa kabusha umhlabathi ombiwe. I-Dholaikhal Main Road, Begum Gonj Lane Main Road,Doyagong Main Road, Kaptan Bazar To Gulistan Main Road, Wari Main Road, Bahadur shahpark road, Gendaria new road, Shahid Faruk Road njll. imigwaqo emikhulu (ububanzi > 4m) endaweni yephrojekthi encane. Eminye imigwaqo ebalulekile yangaphakathi (ububanzi obuyi-2-4 m).
