Amapayipi e-Chuambongnogn e-Dhaka Dwasa Project
Isendlalelo sephrojekthi
Ukuthuthukiswa kwengqalasizinda yasemadolobheni eBangladesh akuzange kugcinwe ijubane ngokufuduka okusheshayo. Ukuhlinzekwa kwamanzi okuphuza e-Bangladesh Capity Dhaka kube yinselele ikakhulukazi.
I-Dhaka Water Supply Network Network Project (DWSSNIP) ihlose ukuthuthukisa ukuhlinzekelwa kwamanzi okuzinzile, okuthembekile, kanye nesimo sezulu eDhaka City. Kuzothuthukisa izinzuzo zokuhlinzekwa kwenethiwekhi yokusabalalisa ngaphansi kwamaphrojekthi webhange langaphambilini lase-Asia (ADB) ekhokhelwa imali ekhokhelwa imali eDhaka Amanzi Okuhlinzekwa Kwamanzi Nezokuthuthwa Kwendle (i-DWASA) yokwakha ukulethwa kwezidingo.
Imisebenzi yokwakha
I-Civil Isebenza kwiphrojekthi ye-Sub Project ikakhulukazi ifaka ukubekwa kwamapayipi okunikezwa kwamanzi okuvela kumadayimitha asukela ku-75 mm kuya ku-400 mm.
Amapayipi we-HDPE anokuqina okuphezulu, isikhathi eside, kanye nokuvimbela ukuqhekeka kwengcindezi futhi asondele - engenamqondo ekuthambekeni okukhulu kwamakhemikhali nakwemvelo. Izici zepayipi zazisho ukuthi zidinga ukulungiswa okuncane kakhulu kunezinye izinto zokushaya kwamapayipi kanye nokuqinisekisa amandla aphezulu okugeleza kwempilo yakhe yonke.
Isixazululo sohlelo lweChuanangGong sifaka amapayipi, ama-electrofulusion Couplers, imishini ye-Electroful, ukwesekwa kobunjiniyela, ithuluzi lokufaka elikhethekile, nokuqeqeshwa.
Le misebenzi izofaka ukuwa kwemivuzo eqondile yokubeka amapayipi eceleni kwemigwaqo, ukubeka amapayipi emseleni, ehlanganayo, ukuhlolwa kwe-hydro nokugcwalisa ngenhlabathi embiwe. I-Dholaikhal Main Road, uGonj Lane Main Road, Doyagong Main Road to Gundistan Main Road, Wari Main Road, i-Bahadur Shahpark Road, i-gendaria argar Road, yi-shahid ftuk road njll. Eminye imigwaqo yangaphakathi ebalulekile (ububanzi 2-4 m).
