Ntchito Yopewera Kutuluka kwa Madzi a Madzi a Madzi a Xizang: Ntchito Yomanga Ma Geomembrane Opangidwa ndi Composite

Malo a Pulojekiti2025, Xizang, China

Mbiri ya Pulojekiti: Malo omanga ali ndi mtunda wautali komanso kutentha kwakukulu pakati pa usana ndi usiku, ndipo mvula ndi chipale chofewa zimagwa nthawi zambiri panthawi yomanga. Damu losungira madzi m'madzi limafuna malo odalirika osalowa madzi kuti chitsulo cholemera chisalowe m'nthaka ndi pansi pa nthaka. Nyengo ya phirili imabweretsa mavuto aakulu pa kusinthasintha kwa zipangizo komanso nthawi yomanga.

Yankho la Pulojekiti: Composite Geomembrane (Kapangidwe ka Composite ka HDPE Geomembrane + Nonwoven Geotextile)

Pulojekitiyi imagwiritsa ntchito geomembrane yophatikizika, yomwe imapangidwa ndi geotextile yosalukidwa kawiri (gawo loteteza) mbali zonse ziwiri ndi gawo lapakati la geomembrane ya polyethylene yochuluka kwambiri (gawo loletsa kutuluka kwa madzi) kudzera mu njira yolumikizirana ndi kutentha. Gawo la geotextile limalimbana ndi kuwonongeka kwa makina kuchokera ku dothi lophimba ndi pansi pake ndipo limatulutsa madzi m'mabowo, pomwe gawo la geomembrane limapanga chotchinga chosalowa madzi ndi kukhuthala kwake kwa mamolekyulu, zomwe zimaletsa kusamuka kwa zakumwa zovulaza.

Ntchitoyi ili m'dera la dziwe la tailings pamtunda wa mamita 3800. Panthawi yomanga, idakumana ndi mvula yambiri komanso chipale chofewa, zomwe zidapangitsa kuti chinyezi cha pansi pa nthaka chisinthe komanso kuchepetsa maola ogwira ntchito tsiku lililonse. Gulu lathu lidasintha njirayo malinga ndi momwe ntchito ikuyendera:

1. Kukonza pamwamba: Chotsani zinyalala zakuthwa kuchokera pansi pa dziwe losambira, linganizani ndi kuzikulunga, kenako ziphimbe ndi nsalu yosalowa madzi kwakanthawi.
2. Kusamalira zinthu zomwe zikusinthasintha: Yatsani zinthu zomwe zakulungidwa mu shedi yosungira kutentha musanamange kuti zinthuzo zisawonongeke chifukwa cha kutentha kochepa; zigwani mwachangu mvula ikagwa komanso chipale chofewa, pogwiritsa ntchito zida zogwirira ntchito zoteteza kuti zisaterereke.
3. Kuyika ndi kuyika: Kutsegula geotextile yophatikizika, kusunga pamwamba pa geomembrane kukhala pathyathyathya; kuyang'ana kwambiri pakukonza gawo la mamita 15 la groove yomangirira, kuyika kumapeto kwa geomembrane mu groove, ndikudzaza kumbuyo kuti apange malire otsekedwa oletsa kutuluka madzi.
4. Yankho lapadera la nyengo: Siyani ntchito yowotcherera nthawi yomweyo chipale chofewa chosayembekezereka chikagwa, phimbani malo owotcherera; kenako yeretsani chinyezi cha pamwamba musanabwererenso kuntchito, ndikuyambitsanso chowotcherera chotentha chosungunuka cha double-track mutatsuka pamwamba.
5. Kuvomereza Ubwino: Tsimikizirani umphumphu wa dongosolo loletsa kutuluka kwa madzi kudzera mu kuyesa kwa kuthamanga kwa msoko wothira weld, ndikuwunika kutseka kwa groove yomangira.

Mu polojekitiyi, chifukwa cha malo okwera kwambiri, kutentha kochepa komanso kupanikizika kochepa kwabweretsa zotsatirapo zazikulu pa gulu lomanga komanso zipangizo zomwe zili mkati mwake. Chifukwa cha ziyeneretso zabwino za gulu lomanga la Zhonglong, ali ndi chidziwitso chokwanira chothana ndi malo ovuta kwambiri ndipo amatha kuonetsetsa kuti ntchitoyi ikupita patsogolo bwino.

Lumikizanani nafe kuti mupeze mtengo!
