I-Custer Avenue Combined Sewer Outflow - Ukwakhiwa Kwendawo Yesitoreji Ne-Dechlorination e-Atlanta, Georgia, USA.
IDolobha lase-Atlanta belithuthukisa kakhulu izinhlelo zalo zokuphakelwa kwendle namanzi kule minyaka embalwa edlule. Ngaphakathi kohlaka lwale miklamo yokwakha, i-DSI Ground Support, i-Salt Lake City, ihileleke ekuhlinzekeni amaphrojekthi amathathu kulawa: i-Nancy Creek, i-Atlanta CSO kanye ne-Custer Avenue CSO.
Ukwakhiwa kwephrojekthi ehlanganisiwe yokuchichima kwendle eCuster Avenue kwaqala ngo-Agasti 2005 futhi kwenziwa nguGunther Nash (ongaphansi kwe-Alberici Group) ngaphansi kwenkontileka yokwakha umklamo. Ukuphothulwa kwayo kulindeleke ekuqaleni kuka-2007.
Izingxenye ezilandelayo zokumba ngaphansi komhlaba ziyingxenye yomsebenzi:
Umgodi wokungena - umphini ojulile ongu-40 m onobubanzi bangaphakathi obungaba ngamamitha angu-5 ozosetshenziselwa ukwakha nokufinyelela.
endaweni yokugcina impahla ngesikhathi sokuphila kwayo,
Indawo yokugcina impahla - igumbi elinamamitha angu-183 ubude elinobude obungu-18 m nobude obuyi-17 m,
Imihubhe exhumayo - imigudu emifushane emise okwesicathulo samahhashi engu-4.5 m,
Ishaft yokungenisa umoya - iyadingeka ukuze kuhlinzekwe umoya omusha endaweni yokugcina.
I-SEM (indlela yokumba elandelanayo) isetshenziswa ukushayela imigudu. Ukubhola okuvamile, ukuqhuma, nokusebenza kwe-muck kulandelwa ukuqinisa idwala ngezinto ezisekelayo ezifana ne-welded wire mesh, amagida e-steel lattice, ama-rock dowels, ama-spiles, ne-shotcrete. Ngaphakathi kobubanzi balo msebenzi wokwakha, i-DSI Ground Support ihlinzeka ngemikhiqizo yokusimamisa umhubhe njenge-welded wire mesh, amabhawodi okushayisana, imigoqo engenalutho engu-32 mm, i-threadbar, amabhawodi okuvikela ukugqwala okuphindwe kabili (ama-DCP Bolt), kanye nezinsiza zehardware ezifana namapuleti, amantongomane. , couplers, inhlaka.
Okugqamile kulo msebenzi wukusetshenziswa kwe-DSI DCP Bolts okokuqala ngqa emazweni aseMelika. Kule ndawo yomsebenzi, kwakudingeka isamba se-3,000 DCP Bolts ngobude obuhlukahlukene ukusuka ku-1.5 m kuya ku-6 m. Yonke imikhiqizo ilethwe ngabakwa-DSI Ground Support, eSalt Lake City, ngesikhathi.
