Munguva pfupi yapfuura, "Socket-Type Flexible Joint Joint Anti-Corrosion Steel Pipe" yakagadzirwa neTianjin Youfa Pipeline Technology Co., Ltd. yakabudirira kupasa ongororo yechigadzirwa chitsva yakarongwa neComprehensive Affairs Bureau yeMinistry of Water Resources. Komiti yekuongorora yaitungamirwa naCheng Dehu kubva kuNyanzvi dzeKomiti yeSouth-to-North Water Diversion Project yeMinistry of Water Resources, naCao Shulin kubva kuHydraulic Metal Structure Quality Inspection and Testing Center achishanda semutevedzeri wesachigaro. Nyanzvi gumi dzine masimba kubva kumasangano anosanganisira 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., uye Shanxi Water Resources and Hydropower Survey and Design Research Institute vakapindawo. Mushure mekunyatsoongorora, komiti yakabvuma chigadzirwa ichi nekubatana kuti chakabudirira uye chakavimbika, chakasvika padanho repamusoro-soro pasi rose, uye yakasimbisa kuti chagadzirira kushandiswa padanho guru.
Li Maojin, Sachigaro weYoufa Group, akapa hurukuro yekugamuchira. Vatungamiriri vaivapo vaisanganisira Chen Kechun, Sachigaro weDare Rinotarisira reYoufa Group uye Sachigaro weYoufa Pipeline Technology, Su Jiuchuan, Maneja Mukuru weYoufa Pipeline Technology, Jiang Jisheng, Mutevedzeri weManeja Mukuru, Gao Zhiling, Chief Engineer, Han Zhilong, Fekitori Director, naHuang Wen, Chief Operating Officer weYoufa Water Conservancy Pipeline Application Research Institute.
Pakutanga kweongororo, vatungamiriri veComprehensive Affairs Bureau yeMinistry of Water Resources nekomiti yenyanzvi vakashanyira horo yekuratidzwa yeYoufa Culture Center. Vakazoongorora nzvimbo yekugadzira, vachiongorora maitiro akakosha ekugadzira, nzvimbo dzekudzora maitiro ekutanga, uye maitiro ekuongorora mhando yemapombi esimbi anochinjika ekudzivirira ngura e socket-type, anosanganisira majoini egasket, majoini egasket maviri, uye ma socket lap-welded connections. Vakabvunza zvakadzama nezvepfungwa dzeR&D dzechigadzirwa, hunyanzvi hwetekinoroji, uye mamiriro ekushandisa anoshanda, vachiziva zvakanyanya sisitimu yekudzora mhando yekambani, kugona kwekugadzira kwepamusoro, uye hunyanzvi hwetekinoroji. Munguva yemusangano wekuongorora, komiti yakatevera zvakadzama Maitiro Ekutonga eKuongorora Chigadzirwa Chitsva cheMinistry of Water Resources, ichiongorora zvakadzama pfupiso yekugadzirwa kwechigadzirwa, mishumo yebvunzo, uye mishumo yesainzi itsva, uye yakaita mibvunzo yakadzama yetekinoroji pamatanho echigadzirwa chikuru.
Kuburikidza nekuongorora magwaro ehunyanzvi, kuteerera mishumo, uye kuongorora R&D nekugadzirwa, komiti yekuongorora yakasimbisa zvakanakira chigadzirwa ichi, ichicherechedza hunyanzvi mukugadzira, kugadzira, uye kugadzira michina inodzivirira ngura. Chigadzirwa ichi chakatoshandiswa zvinobudirira mumapurojekiti akawanda akakosha, zvichiwana mabhenefiti akakosha ehupfumi nemagariro evanhu. Komiti yekuongorora yakabvumirana kuti tekinoroji yese yechigadzirwa ichi yasvika padanho repamusoro-soro pasi rose uye yakabvumirana kuchibvumidza kuburikidza neNew Product Appraisal yeMinistry of Water Resources.
Vasati vapasa ongororo iyi, chigadzirwa ichi chakanga chatoshandiswa zvinobudirira mumapurojekiti akawanda enyika, kusanganisira chirongwa chekuchengetedza mvura cheBeijing Winter Olympics, chirongwa chekutsigira Jiang–Huai Water Diversion, uye Shanxi Major Water Network, uye chakagamuchira mibairo yakawanda yakadai se2025 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), uye 2024 Tianjin Smart Factory for Socket-Type Flexible Steel-Plastic Composite Pipes. Kubva pakusimbiswa kwechokwadi mumapurojekiti makuru emvura enyika kusvika pakuzivikanwa kuburikidza nehunyanzvi hwemvumo, kubudirira kwega kwega kunoratidza hunyanzvi hutsva hwevashandi veYoufa. Izvi hazvingosimbisi chete mashandiro echigadzirwa uye mhando yacho asiwo zvinotsigira kushandiswa kwacho kwakakura muma network ekupa mvura. Chigadzirwa ichi chinosanganisira "vimbiso yekuchengetedzwa nhanhatu" yakazara yekugadzirisa matambudziko makuru einjiniya:
1. Kudzora Mutengo - Kune DN600, mari inochengetedzwa inodarika 200,000 RMB pakiromita
Kubatanidza masokisi hakudi vanowedera vane hunyanzvi; vashandiwo zvavo vanobhadhara 300 RMB/zuva vanogona kushanda, zvichienzaniswa ne800 RMB/zuva kune vanowedera vane hunyanzvi. Mari yekugadzirisa weld (400 RMB pajoini) inochengetedzwa, uye nguva yekuvaka inoderedzwa kubva pamazuva makumi maviri/km kusvika pamazuva mashanu/km. Mari yese yemapaipi eDN600 inoderera kubva pa250,000 RMB/km kusvika pa35,000 RMB/km, zvichiita kuti mari ideredzwe nekukurumidza.
2. Kuwedzera Kushanda Nesimba - Kukurumidza kuiswa kwakawedzera kagumi
Maitiro e "plug-and-stabilize" anobvisa kusveta. Pachirongwa cheAnhui Jieshou, mapoka maviri akapedza makiromita masere mumazuva gumi nemashanu, achimhanya avhareji yemamita mazana mashanu pazuva. Kuisa hakukuvadzi layer yekudzivirira ngura, kubvisa kugadziriswa kwechipiri uye kusangana nezvinodiwa nekukurumidza zvemapurojekiti ekuchengetedza mvura.
3. Kushanda Kwepasi Pose Kwepasi
Majoini ekare akasungirirwa akaomarara uye haagone kusunungura kushushikana, nepo majoini emasokisi anochinjika, achishandura mapaipi kubva "kumatanda marefu anotsemuka nyore nyore" kuita "magadzirirwo akafanana necheni anochinjika". Makona ejoini rimwe nerimwe anotenderera anosvika 1°30′–3°30′.
4. Kuramba Kuora Kunogara Kwenguva Refu – Hupenyu hwese hunopfuura makore makumi mashanu
Hunhu hwekuiswa hunosimbiswa. Mapaipi esimbi akaputirwa anoshanda pasi pe2.5 MPa ane chokwadi chekuti acharamba achishanda zvakachengeteka kwemakore makumi mashanu, achichinjika kunzvimbo dzakaoma dzakadai semateru nemakwara. Kusayerera kwemvura kwakaderera uye kurasikirwa kushoma kwemusoro kunoderedza mari yemagetsi kwenguva refu.
5. Kugadzirisa Kwakaderera - Kuderedzwa kwemitengo inodarika 30%
Kune mapaipi esimbi eDN630 nemadiki, kugadzirisa mukati mushure mekuweldwa kwakaoma. Nzvimbo shoma yekushanda inoita kuti zviome kuisa layer yekudzivirira ngura zvakaenzana, zvichikonzera nzvimbo dzisina kusimba uye ngura inogona kuitika mune ramangwana. Kubatanidza masokisi kunoda kugadziriswa kushoma, zvichideredza mari yekugadzirisa kwenguva refu neinopfuura 30%, zvichiratidza kushanda zvakanaka kwemari.
6. Kuvaka Kwakachengeteka - Njodzi Dzinodzivirirwa Zvizere
Hapana murazvo wakavhurika kana acetylene inodiwa, zvichibvisa njodzi dzemoto. Kushanda kuri nyore kunoderedza simba revashandi neanopfuura 50%, zvichideredza matambudziko emhando yekuneta uye kuve nechokwadi chekuti kuvaka kwakachengeteka.
Tichitarisa mberi, Youfa Pipeline Technology ichatora kuongororwa kwakabudirira kwechigadzirwa ichi senzvimbo itsva yekutanga. NeTianjin Youfa Water Conservancy Pipeline Application Research Institute sesimba guru, uye ichitsigirwa nehurongwa hweBoka munyika yese nekune dzimwe nyika, kambani icharamba ichitarisa pane zvinodiwa zvekuvandudza mapurojekiti ekuchengetedza mvura. Padanho rino rakakosha re "Chirongwa chemakore mashanu chegumi nemashanu" chenyika chekuvandudza kuchengetedza mvura, China iri kufambira mberi zvizere nekuvaka sisitimu yemazuva ano yemvura. Mikana mikuru iri kuburitswa munzvimbo dzakadai semapurojekiti ekuparadzanisa mvura pakati pemabheseni, kuvandudza matunhu ekudiridza, kuchengetedzeka kwemvura kumaruwa, uye kuchengetedza mvura mbiri dzedhijitari, zvichipa nzvimbo yakakura yekuvandudza nekushandisa matekinoroji emapaipi epamusoro.
Tinokoka nemwoyo wose masangano ekugadzira, mayunivhesiti, mayunivhesiti ekuvaka, uye vadyidzani vemaindasitiri mumunda weinjiniya wekuchengetedza mvura wemuno newepasi rose kuti vabatane, vagovane zvakaitwa netekinoroji, vashandise mikana yegoridhe ye "Chirongwa chemakore mashanu chechi15" chekuvandudza kuchengetedza mvura, vaongorore pamwe chete mikana mitsva yemusika, uye vawane mabhenefiti pamwe chete uye mhedzisiro inobatsira vose mukushandira hurongwa hwekuchengetedza mvura hwenyika.
