Kutshanje, i-"Socket-Type Flexible Joint Joint Anti-Corrosion Steel Pipe" eyenziwe yiTianjin Youfa Pipeline Technology Co., Ltd. iphumelele ngempumelelo uvavanyo olutsha lwemveliso oluququzelelwe yi-Comprehensive Affairs Bureau yeSebe leMithombo yamanzi. Ikomiti yovavanyo yayikhokelwa nguCheng Dehu ovela kwiKomiti yeeNgcali yeProjekthi yokuPhambuka kwamanzi eSouth-to-North yeSebe leMithombo yamanzi, kunye noCao Shulin ovela kwiZiko loVavanyo loMgangatho weHydraulic Metal Structure esebenza njengosekela-sihlalo. Iingcali ezilishumi ezinegunya ezivela kumaziko aquka iYangtze River Survey, iPlanning and Design Co., Ltd., iShandong Water Conservancy Survey and Design Institute Co., Ltd., iWater Resources and Hydropower Planning and Design General Institute yeSebe leMithombo yamanzi, iYellow River Survey and Design Institute Co., Ltd., iTianjin University, iChina Water North Survey and Design Research Co., Ltd., kunye neShanxi Water Resources and Hydropower Survey and Design Research Institute bathathe inxaxheba. Emva kovavanyo olunzulu, ikomiti yamkela ngazwi linye imveliso njengephucukileyo kwezobuchwepheshe kwaye inokuthenjwa, iyonke ifikelela kwinqanaba eliphambili kwihlabathi liphela, kwaye yaqinisekisa ukuba ilungele ukusetyenziswa ngobuninzi.
ULi Maojin, uSihlalo weYoufa Group, unikele intetho yokwamkela. Iinkokeli ezazikho ziquka uChen Kechun, uSihlalo weBhodi yoLawulo yeYoufa Group kunye noSihlalo weYoufa Pipeline Technology, uSu Jiuchuan, uMphathi Jikelele weYoufa Pipeline Technology, uJiang Jisheng, uSekela Mphathi Jikelele, uGao Zhiling, iNjineli eyiNtloko, uHan Zhilong, uMlawuli weFektri, kunye noHuang Wen, iGosa eliyiNtloko eliSebenzayo leYoufa Water Conservancy Pipeline Application Research Institute.
Ekuqaleni kovavanyo, iinkokeli ezivela kwi-Comprehensive Affairs Bureau yeSebe leMithombo yamanzi kunye nekomiti yeengcali zityelele iholo yomboniso yeZiko leNkcubeko laseYoufa. Emva koko zenze uhlolo kwindawo yokusebenzela yemveliso, zihlola iinkqubo eziphambili zemveliso, iindawo zokulawula inkqubo ephambili, kunye neenkqubo zokuhlola umgangatho ezipheleleyo zemibhobho yentsimbi eguquguqukayo yohlobo lwesokhethi, kubandakanya amalungu e-single-gasket, amalungu e-double-gasket, kunye noqhagamshelo oludibeneyo lwesokhethi. Babuze ngokweenkcukacha malunga neengcamango zophando nophuhliso lwemveliso, izinto ezintsha zobugcisa, kunye neemeko zokusebenza ezisebenzayo, beqaphela kakhulu inkqubo yokulawula umgangatho engqongqo yenkampani, amandla okuvelisa aphucukileyo, kunye nokuvelisa ubuchwepheshe. Ngexesha lentlanganiso yovavanyo, ikomiti ilandele ngokungqongqo iMilinganiselo yoLawulo yoVavanyo lweMveliso eNtsha yeSebe leMithombo yamanzi, ihlola ngokupheleleyo isishwankathelo sophuhliso lwemveliso, iingxelo zovavanyo, kunye neengxelo ezintsha zesayensi, kwaye yenze imibuzo yobuchwepheshe enzulu kwiiparameter eziphambili zemveliso.
Ngokuphonononga amaxwebhu obuchwephesha, ukumamela iingxelo, nokuhlola uphando kunye nophuhliso kunye nemveliso, ikomiti yovavanyo iqinisekisile ngokupheleleyo iingenelo zemveliso, iphawula izinto ezintsha kuyilo lwesakhiwo esidibeneyo, ukwakheka, kunye nophuhliso lwezixhobo zokulwa nokugqwala. Le mveliso sele isetyenziswe ngempumelelo kwiiprojekthi ezininzi eziphambili, ifezekisa iingenelo ezibalulekileyo kwezoqoqosho nakwezentlalo. Ikomiti yovavanyo igqibe ngazwi linye ukuba ubuchwepheshe bemveliso iyonke bufikelele kwinqanaba eliphambili kwihlabathi liphela kwaye yavuma ukuyivuma ngoVavanyo lweMveliso eNtsha loMphathiswa weMithombo yamanzi.
Ngaphambi kokuba kudlule uvavanyo, imveliso yayisele isetyenziswe ngempumelelo kwiiprojekthi ezininzi eziphambili zesizwe, kubandakanya iprojekthi yomthombo wamanzi ogciniweyo kwiOlimpiki zasebusika zaseBeijing, iprojekthi yokuxhasa iJiang-Huai Water Diversion, kunye neShanxi Major Water Network, kwaye ifumene iimbeko ezininzi ezifana neKhathalogu yeSikhokelo sokuKhuthazwa okuPhambili ngo-2025 yeeTekhnoloji eziPhambili eziSebenzayo kwiNdawo yokuLondoloza Amanzi, uluhlu lweMinistry of Water Resources List of Advanced Mature and Applicable Water-Saving Technologies, i-2025 Typical Case of New Quality Productivity Development in Private Enterprises (Quality and Standardization Category), kunye ne-2024 Tianjin Smart Factory for Socket-Type Flexible Steel-Plastic Composite Pipes. Ukususela ekuqinisekisweni okusebenzayo kwiiprojekthi ezinkulu zamanzi zesizwe ukuya ekuqaphelweni ngeziqinisekiso ezigunyazisiweyo, impumelelo nganye ibonisa ubuchule obutsha babasebenzi beYoufa. Oku akuqinisekisi kuphela ukusebenza kunye nomgangatho wemveliso kodwa kuxhasa kakhulu ukusetyenziswa kwayo ngokubanzi kwiinethiwekhi zokubonelela ngamanzi. Imveliso ibandakanya "isiqinisekiso sokhuseleko esithandathu" esibanzi sokujongana nemingeni ephambili yobunjineli:
1. Ulawulo lweendleko – Kwi-DN600, ukonga kudlula i-200,000 RMB ngekhilomitha nganye
Uqhagamshelo lweesokhethi alufuni bathungi abakhethekileyo; abasebenzi abaqhelekileyo abaxabisa i-300 RMB/ngosuku banokusebenza, xa kuthelekiswa ne-800 RMB/ngosuku kubathungi abaziingcali. Iindleko zezinto zokwakha zokulungisa ii-weld (400 RMB ngejoyinti) ziyalondolozwa, kwaye ixesha lokwakha liyancitshiswa ukusuka kwiintsuku ezingama-20/km ukuya kwiintsuku ezi-5/km. Iindleko zizonke zemibhobho ye-DN600 ziyehla ukusuka kwi-250,000 RMB/km ukuya kwi-35,000 RMB/km, nto leyo efezekisa ukuncitshiswa kweendleko ngoko nangoko.
2. Ukunyusa ukusebenza kakuhle – Isantya sokufakela sinyuke ngokuphindwe kalishumi
Indlela "yokufaka umbane nokuzinzisa" ayivumeli ukuwelda. Kwiprojekthi yase-Anhui Jieshou, amaqela amabini agqibe iikhilomitha ezisi-8 kwiintsuku ezili-15, umyinge weemitha ezingama-500 ngosuku. Ukufakelwa akuwonakalisi umaleko wokulwa nokugqwala, kususa ukulungiswa kwesibini kwaye kuhlangabezana neemfuno zeshedyuli ezikhawulezileyo zeeprojekthi zokugcina amanzi.
3. Ukusebenza Okugqwesileyo Kwe-Seismic
Iijoyinti zemveli ezidityanisiweyo ziqinile kwaye azinakukhulula uxinzelelo, ngelixa iijoyinti zesokhethi ziguquguquka, ziguqula imibhobho ukusuka "kwimiqadi emide eqhekeka lula" ibe "zizakhiwo ezifana netyathanga eziguquguqukayo". Ii-engile zokujika kwejoyinti nganye zifikelela kwi-1°30′–3°30′.
4. Ukumelana Nokugqwala Okuhlala Ixesha Elide – Ubomi obungaphezulu kweminyaka engama-50
Umgangatho wokufakelwa uyaqinisekiswa. Iipayipi zentsimbi ezigqunywe ngeplastiki ezisebenza ngaphantsi kwe-2.5 MPa ziqinisekisiwe ukuba ziya kusebenza ngokukhuselekileyo iminyaka engama-50, zilungelelanisa neendawo ezinzima ezifana namathambeka kunye neendawo zokunqumla. Ukumelana nokuhamba kwamanzi okuphantsi kunye nokulahleka okuncinci kwentloko kunciphisa iindleko zamandla zexesha elide.
5. Ukugcinwa Okuphantsi – Ukunciphisa iindleko ngaphezulu kwama-30%
Kwimibhobho yentsimbi ye-DN630 kunye nemincinci, ukulungiswa kwangaphakathi emva kokuwelda kunzima. Indawo encinci yokusebenza yenza kube nzima ukufaka umaleko ochasene nokugqwala ngokulinganayo, nto leyo ebangela iindawo ezibuthathaka kunye nokugqwala okunokwenzeka kwixesha elizayo. Uqhagamshelo lwesokhethi lufuna ukulungiswa okuncinci, okunciphisa iindleko zokugcinwa kwexesha elide ngaphezulu kwe-30%, nto leyo egxininisa ukusebenza kakuhle kwezoqoqosho.
6. Ulwakhiwo Olukhuselekileyo – Ingozi Ithintelwe Ngokupheleleyo
Akukho mfuneko yomlilo okanye i-acetylene kwindawo evulekileyo, nto leyo esusa iingozi zomlilo. Ukusebenza okulula kunciphisa amandla abasebenzi ngaphezulu kwama-50%, kunciphisa imiba enxulumene nokudinwa kunye nokuqinisekisa ulwakhiwo olukhuselekileyo.
Ukujonga phambili, iYoufa Pipeline Technology iza kuthatha uvavanyo oluphumeleleyo lwale mveliso njengendawo entsha yokuqala. Nge-Tianjin Youfa Water Conservancy Pipeline Application Research Institute njengamandla aqhubayo, kwaye ixhaswa luyilo lweqhinga leQela kuzwelonke nakwamanye amazwe, inkampani iya kuqhubeka nokugxila kwiimfuno zophuhliso ezisemgangathweni ophezulu zeeprojekthi zokugcina amanzi. Kweli nqanaba libalulekileyo le-"15th Five-Year Plan" yelizwe yokuphucula ukongiwa kwamanzi, iTshayina iqhubela phambili ngokupheleleyo ukwakhiwa kwenkqubo yenethiwekhi yamanzi yanamhlanje. Amathuba amakhulu akhululwa kwiindawo ezifana neeprojekthi zokuhambisa amanzi phakathi kwezitya, ukuphuculwa kwesithili sokunkcenkceshela, ukhuseleko lobonelelo lwamanzi asemaphandleni, kunye nokongiwa kwamanzi kabini ngedijithali, okubonelela ngendawo ebanzi yokuvelisa izinto ezintsha kunye nokusetyenziswa kobuchwepheshe bepayipi obuphezulu.
Simema ngokunyanisekileyo amaziko oyilo, iiyunivesithi, iiyunithi zokwakha, kunye namaqabane oshishino kwicandelo lobunjineli bokugcinwa kwamanzi basekhaya nakwamanye amazwe ukuba basebenzisane, babelane ngempumelelo yetekhnoloji, basebenzise amathuba egolide "eSicwangciso seMinyaka emihlanu se-15" sophuhliso lokugcinwa kwamanzi, baphonononge kunye amathuba amatsha emarike, kwaye bafezekise iziphumo ezizuzisayo zombini kunye neziphumo ezizuzisayo ekukhonzeni icebo lokhuseleko lwamanzi lesizwe.
