Posachedwapa, "Socket-Type Flexible Joint Joint Anti-Corrosion Steel Pipeline" yopangidwa ndi Tianjin Youfa Pipeline Technology Co., Ltd. yapambana bwino kuwunika kwatsopano kwa malonda komwe kunakonzedwa ndi Comprehensive Affairs Bureau of the Ministry of Water Resources. Komiti yowunikirayi idatsogozedwa ndi Cheng Dehu kuchokera ku Komiti Yodziwa za Project ya South-to-North Water Diversion ya Ministry of Water Resources, ndipo Cao Shulin wochokera ku Hydraulic Metal Structure Quality Inspection and Testing Center anali wachiwiri kwa wapampando. Akatswiri khumi odziwika bwino ochokera m'mabungwe kuphatikizapo Yangtze River Survey, Planning and Design Co., Ltd., Shandong Water Conservancy Survey and Design Institute Co., Ltd., Water Resources and Hydropower Planning and Design General Institute of the Ministry of Water Resources, Yellow River Survey and Design Institute Co., Ltd., Tianjin University, China Water North Survey and Design Research Co., Ltd., ndi Shanxi Water Resources and Hydropower Survey and Design Research Institute adatenga nawo mbali. Pambuyo pofufuza mosamala, komitiyi idavomereza kuti malondawa ndi apamwamba kwambiri paukadaulo komanso odalirika, onse akufika pamlingo wapamwamba padziko lonse lapansi, ndipo idatsimikiza kuti ndi okonzeka kugwiritsidwa ntchito pamlingo waukulu.
Li Maojin, Wapampando wa Youfa Group, ndi amene anakamba nkhani yolandirira alendo. Atsogoleri omwe analipo anali Chen Kechun, Wapampando wa Bungwe Loyang'anira la Youfa Group komanso Wapampando wa Youfa Pipeline Technology, Su Jiuchuan, Woyang'anira Wamkulu wa Youfa Pipeline Technology, Jiang Jisheng, Wachiwiri kwa Woyang'anira Wamkulu, Gao Zhiling, Mainjiniya Wamkulu, Han Zhilong, Mtsogoleri wa Fakitale, ndi Huang Wen, Woyang'anira Wamkulu wa Youfa Water Conservancy Pipeline Application Research Institute.
Poyamba kuwunika, atsogoleri ochokera ku Comprehensive Affairs Bureau of the Ministry of Water Resources ndi komiti ya akatswiri adapita ku holo yowonetsera ya Youfa Culture Center. Kenako adachita kuwunika komweko kwa malo opangira zinthu, kuwunika njira zofunika zopangira, malo owongolera njira zoyambira, ndi njira zonse zowunikira khalidwe la mapaipi achitsulo osinthika a socket-type anti-corrosion, kuphatikiza ma single-gasket joints, ma double-gasket joints, ndi ma socket lap-welded connections. Adafunsa mwatsatanetsatane za malingaliro a R&D a chinthucho, zatsopano zaukadaulo, ndi zochitika zogwiritsidwa ntchito moyenera, pozindikira kwambiri njira yowongolera khalidwe la kampaniyo, luso lapamwamba lopangira, ndi zatsopano zaukadaulo. Pamsonkhano wowunika, komitiyi idatsatira mosamala Miyezo Yoyang'anira Kuwunika Zatsopano za Unduna wa Zamadzi, kuwunikanso bwino chidule cha chitukuko cha chinthucho, malipoti oyesa, ndi malipoti asayansi atsopano, ndipo adachita mafunso aukadaulo ozama pa magawo akuluakulu a chinthucho.
Kudzera mukuwunikanso zikalata zaukadaulo, kumvetsera malipoti, ndikuyang'ana kafukufuku ndi chitukuko ndi kupanga, komiti yowunikira idatsimikiza mokwanira zabwino za chinthucho, ndikuwona zatsopano pakupanga kapangidwe kogwirizana, kupanga, ndi kupanga zida zotsutsana ndi dzimbiri. Chinthucho chagwiritsidwa kale ntchito bwino m'mapulojekiti ambiri ofunikira, zomwe zapeza phindu lalikulu pazachuma komanso chikhalidwe cha anthu. Komiti yowunikira idatsimikiza mogwirizana kuti ukadaulo wonse wa chinthucho wafika pamlingo wapamwamba padziko lonse lapansi ndipo idavomereza kuti ichivomereze kudzera mu Kuwunika Kwatsopano kwa Zinthu za Unduna wa Zamadzi.
Asanapereke mayeso, mankhwalawa anali atagwiritsidwa ntchito kale bwino m'mapulojekiti akuluakulu adziko lonse, kuphatikizapo pulojekiti yosungira madzi ya Olimpiki ya Zima ku Beijing, pulojekiti yothandizira ya Jiang-Huai Water Diversion, ndi Shanxi Major Water Network, ndipo alandira ulemu wambiri monga 2025 Key Promotion Guide Catalog of Advanced Practical Technologies in Water Conservancy, 2025 Ministry of Water Resources List of Advanced Mature and Applicable Water-Saving Technologies, 2025 Typical Case of New Quality Productivity Development in Private Enterprises (Quality and Standardization Category), ndi 2024 Tianjin Smart Factory for Socket-Type Flexible Steel-Plastic Composite Pipes. Kuyambira kutsimikizira kogwira ntchito m'mapulojekiti akuluakulu adziko lonse mpaka kuzindikirika kudzera mu ziyeneretso zovomerezeka, kupambana kulikonse kukuwonetsa luso lapamwamba la antchito a Youfa. Izi sizimangotsimikizira magwiridwe antchito ndi mtundu wa mankhwalawa komanso zimathandizira kwambiri kugwiritsidwa ntchito kwake kwakukulu m'maukonde operekera madzi. Chogulitsachi chimaphatikizapo "chitsimikizo chachitetezo zisanu ndi chimodzi" chokwanira kuti chithetse mavuto akuluakulu aukadaulo:
1. Kuwongolera Mtengo - Pa DN600, ndalama zosungidwa zimaposa 200,000 RMB pa kilomita
Kulumikiza ma soketi sikufuna odulira apadera; antchito wamba omwe amalemera 300 RMB/tsiku amatha kugwira ntchito, poyerekeza ndi 800 RMB/tsiku kwa odulira akatswiri. Ndalama zokonzera zodulira (400 RMB pa cholumikizira chilichonse) zimasungidwa, ndipo nthawi yomanga imachepetsedwa kuchoka pa masiku 20/km kufika pa masiku 5/km. Mtengo wonse wa mapaipi a DN600 umatsika kuchoka pa 250,000 RMB/km kufika pa 35,000 RMB/km, zomwe zimapangitsa kuti ndalama zichepe nthawi yomweyo.
2. Kukweza Mphamvu - Kuthamanga kwa kukhazikitsa kwawonjezeka kakhumi
Njira ya "plug-and-stabilize" imachotsa kuwotcherera. Pa projekiti ya Anhui Jieshou, magulu awiri adamaliza mtunda wa makilomita 8 m'masiku 15, pafupifupi mamita 500 patsiku. Kukhazikitsa sikuwononga gawo loletsa dzimbiri, kumachotsa kukonzanso kwina ndikukwaniritsa zofunikira za nthawi yofulumira ya mapulojekiti osamalira madzi.
3. Kuchita Bwino Kwambiri kwa Chivomerezi
Malumikizidwe achikhalidwe olumikizidwa ndi olimba ndipo sangatulutse kupsinjika, pomwe malumikizidwe a soketi ndi osinthasintha, kusintha mapaipi kuchokera ku "miyala yayitali yosweka mosavuta" kukhala "mapangidwe osinthika ofanana ndi unyolo". Ma ngodya a malumikizidwe amodzi amafika 1°30′–3°30′.
4. Kukana Kudzimbiri Kokhalitsa - Moyo wa zaka zoposa 50
Ubwino wa kukhazikitsa ukutsimikizika. Mapaipi achitsulo okhala ndi zokutira omwe amagwira ntchito pansi pa 2.5 MPa akutsimikizika kuti azigwira ntchito bwino kwa zaka 50, akusinthana ndi malo ovuta monga mapiri ndi malo odutsa. Kukana kuyenda kwa madzi pang'ono komanso kutayika kochepa kwa mutu kumachepetsa ndalama zogulira mphamvu kwa nthawi yayitali.
5. Kukonza Kochepa - Kuchepetsa ndalama zopitilira 30%
Pa mapaipi achitsulo a DN630 ndi ang'onoang'ono, kukonza mkati mwa payipi pambuyo pa weld kumakhala kovuta. Malo ochepa ogwirira ntchito amapangitsa kuti zikhale zovuta kugwiritsa ntchito mofanana gawo loletsa dzimbiri, zomwe zimapangitsa kuti pakhale malo ofooka komanso dzimbiri mtsogolo. Kulumikiza kwa socket kumafuna kukonzedwa kochepa, zomwe zimachepetsa ndalama zosamalira kwa nthawi yayitali ndi zoposa 30%, zomwe zikuwonetsa magwiridwe antchito abwino.
6. Ntchito Yomanga Yotetezeka - Kupewa Ngozi Konse
Palibe chifukwa chogwiritsa ntchito lawi lotseguka kapena asetilini pamalopo, zomwe zimachotsa zoopsa za moto. Kugwira ntchito kosavuta kumachepetsa mphamvu ya antchito ndi 50%, kuchepetsa mavuto okhudzana ndi kutopa komanso kuonetsetsa kuti zomangamanga zili bwino.
Poganizira zamtsogolo, Youfa Pipeline Technology idzatenga kuwunika bwino kwa mankhwalawa ngati poyambira patsopano. Ndi Tianjin Youfa Water Conservancy Pipeline Application Research Institute ngati mphamvu yoyendetsera ntchito, komanso yothandizidwa ndi dongosolo la Gulu lonse komanso lakunja, kampaniyo ipitiliza kuyang'ana kwambiri zosowa zapamwamba za mapulojekiti osungira madzi. Pa gawo lofunika kwambiri la "Pulani ya Zaka Zisanu ya 15" ya dzikolo yokonzanso kusungira madzi, China ikupititsa patsogolo ntchito yomanga njira zamakono zopezera madzi. Mwayi waukulu ukuperekedwa m'malo monga mapulojekiti osinthira madzi pakati pa zitsime, kukonzanso madera othirira madzi, chitetezo cha madzi akumidzi, ndi kusungira madzi awiri a digito, kupereka malo ambiri opangira zatsopano ndikugwiritsa ntchito ukadaulo wapamwamba wa mapaipi.
Tikuyitanitsa moona mtima mabungwe opanga mapulani, mayunivesite, mayunivesiti omanga, ndi ogwira nawo ntchito m'makampani osiyanasiyana m'munda waukadaulo wosamalira madzi m'dziko muno komanso padziko lonse lapansi kuti agwirizane, agawane zomwe zachitika paukadaulo, agwiritse ntchito mwayi wagolide wa "Pulani ya Zaka Zisanu ya 15" yopititsa patsogolo kusungira madzi, afufuze pamodzi mwayi watsopano wamsika, ndikupindula ndi onse awiri komanso phindu pokwaniritsa njira yotetezera madzi mdziko lonse.
