CHUANGROGN Piping hauv Dhaka DWASA Project
Qhov project Background
Kev loj hlob ntawm nroog infrastructure hauv Bangladesh tsis tau ua raws li kev loj hlob sai. Kev muab dej haus hauv Bangladesh lub nroog nroog Dhaka tau nyuaj tshwj xeeb.
Dhaka Water Supply Network Improvement Project (DWSNIP) lub hom phiaj los txhim kho kev muab cov dej kom ruaj khov, txhim khu kev qha, thiab kev nyab xeeb-resilient dej hauv Dhaka lub nroog. Nws yuav txhim kho kev faib khoom lag luam kom tau txais txiaj ntsig ua tiav raws li ob lub tuam txhab Asian Development Bank (ADB) yav dhau los tau txais nyiaj txiag rau Dhaka Water Supply and Sewerage Authority (DWASA) rau kev txhim kho kev xa khoom thiab kev tsim peev txheej.
Kev tsim kho ua haujlwm
Kev ua haujlwm hauv pej xeem hauv txoj haujlwm me feem ntau suav nrog kev tso cov kav dej los ntawm txoj kab uas hla ntawm 75 hli mus rau 400 hli.
Cov kav dej HDPE muaj qhov ua tau zoo dua qub, kev ua neej ntev, thiab kev ntxhov siab tawg ua haujlwm thiab nyob ze-ua rau feem ntau cov tshuaj lom neeg thiab lom fouling. Cov yeeb nkab cov yam ntxwv txhais tau tias yuav tsum tau saib xyuas tsawg dua li lwm cov khoom siv hauv cov kav dej thiab ua kom muaj peev xwm txaus siab thoob plaws hauv nws lub neej kev pabcuam.
ChuangRong system daws teeb meem suav nrog cov kav dej, electrofusion couplers, electrofusion tshuab, kev txhawb nqa engineering, kev teeb tsa tshwj xeeb, thiab kev cob qhia.
Cov kev ua haujlwm no yuav suav nrog kev khawb hauv kab rau kev tso cov kav dej raws txoj kev, tso cov kav dej hauv cov trench, kev sib koom ua ke, kev sim hydro-testing thiab refilling nrog cov av excavated. Dholaikhal Main Road, Begum Gonj Lane Main Road, Doyagong Main Road, Kaptan Bazar To Gulistan Main Road, Wari Main Road, Bahadur shahpark txoj kev, Gendaria txoj kev tshiab, Shahid Faruk Road thiab lwm yam yog txoj kev loj (dav> 4m) nyob rau hauv lub subproject cheeb tsam. Lwm yam tseem ceeb hauv txoj kev (dav 2-4 m).
