Ukubaluleka Kwepayipi Elisikiwe Nelihlanganisiwe Engqalasizinda Yesimanje, Enhliziyweni yeCangzhou, eSifundazweni saseHebei, kunendawo yokugaya insimbi ebilokhu iyitshe lesisekelo embonini yamapayipi ensimbi selokhu yasungulwa ngo-1993. Le nkampani ihlanganisa amamitha-skwele angu-350,000, inempahla ephelele engu-680 million RMB, futhi iqashe abasebenzi abazinikele abangu-680. Phakathi kwemikhiqizo yayo eminingi kukhona amapayipi asikiwe futhi ahlanganisiwe, okuyingxenye ebalulekile yengqalasizinda yesimanje, ikakhulukazi ekuthuthweni kwamanzi angaphansi komhlaba.
Ngaphansi komhlabaIpayipi Elihlanganisiwe Lasahwazibalulekile ekuthuthweni kwamanzi ngendlela ephumelelayo nethembekile ezindaweni ezahlukahlukene. Zakha umgogodla wengqalasizinda yethu yesimanje, ziqinisekisa ukuthi amanzi ahlanzekile afinyelela emakhaya, emabhizinisini nasezindaweni zezolimo. Ukukhetha izinto zala mapayipi kubalulekile, njengoba kumele amelane nezingcindezi zemvelo engaphansi komhlaba ngenkathi egcina ubuqotho bawo besikhathi eside. Enye yezinketho ezithandwa kakhulu kulezi zinhlelo zokusebenza ipayipi lensimbi yekhabhoni elihlanganisiwe nge-spirally, elidume ngamandla alo nokuqina kwalo.
Ipayipi lensimbi eliyindilinga le-S235 JR kanye nepayipi lomugqa le-X70 SSAW (Spiral Submerged Arc Welded) yimikhiqizo emibili ejwayelekile esetshenziswa kabanzi ezinhlelweni zamapayipi amanzi angaphansi komhlaba. Ipayipi le-S235 JR lihlonishwa kakhulu ngezakhiwo zalo ezinhle kakhulu zemishini, okwenza lifanelekele izinhlelo ezahlukahlukene, okuhlanganisa nokuthuthwa kwamanzi. Amandla alo okumelana nokuguquguquka ngaphansi kokucindezeleka aqinisekisa ukuthi lihlangabezana nezidingo zezikhungo ezingaphansi komhlaba.
Namuhla, ngenqubo yokusheshisa ukukhula kwamadolobha, uhlelo lokudlulisa amanzi angaphansi komhlaba oluthembekile seluyisihluthulelo sokuqinisekisa impilo yabantu. Njengebhizinisi elihamba phambili embonini yokukhiqiza amapayipi ensimbi, isitshalo esithile sensimbi eDolobheni laseCangzhou, eSifundazweni saseHebei, besilokhu sihlinzeka ngamapayipi e-Saw Welded asebenza kahle kakhulu engqalasizinda yomhlaba wonke selokhu sasungulwa ngo-1993. Amapayipi aso ensimbi e-S235 JR spiral kanye namapayipi e-spiral e-X70 angaphansi komhlaba ahlanganiswe nge-arc, anezakhiwo zawo ezivelele zemishini, abe yizinto eziyinhloko zamaphrojekthi okulondolozwa kwamanzi angaphansi komhlaba.
1. Amandla aphezulu kanye nokumelana nokugqwala kuqinisekisa ukuphepha kokudluliswa kwamanzi isikhathi eside. Ipayipi elijikelezayo le-S235 JR: Linokumelana okuhle kakhulu nokuguquguquka kokucindezeleka futhi lifanelekela izindawo eziyinkimbinkimbi ze-geological, liqinisekisa ukusebenza okuzinzile kwesikhathi eside kwepayipi. Ipayipi le-X70 SSAW: Lenziwe ngensimbi enamandla aphezulu kanye nobuchwepheshe obuthuthukisiwe bokushisela okujikelezayo, alinakucindezela futhi alinakumelana nokugqwala, lifanele ukudluliswa kwamanzi akude kanye nezindawo ezinzima.
2. Ubuchwepheshe obuthuthukisiwe obuhlanganiswe nokulawulwa kwekhwalithi okuqinile kudala uhlelo lwamapayipi oluzinzile. Le fektri isebenzisa ubuchwepheshe bokushisela i-spiral submerged arc (SAW) ukuze kufezwe ukukhiqizwa okuphumelelayo kwamapayipi amakhulu, anodonga oluncane, kuthuthukisa ukusetshenziswa kwezinto ngenkathi kuqinisekiswa amandla. Ngokubambisana nethimba lochwepheshe labantu abangu-680 kanye nomugqa wokukhiqiza wesimanje obiza ama-yuan ayizigidi ezingu-680, siqinisekisa ukuthi wonke amapayipi ensimbi ahlangabezana nezindinganiso zomhlaba wonke, afaka isandla ekuthuthukisweni kwengqalasizinda eluhlaza. Ngokuthuthukisa izidingo zokuphathwa kwemithombo yamanzi emhlabeni jikelele, amapayipi ashiselwe ngosaha eCangzhou Steel Plant azoqhubeka nokuhlinzeka ngezixazululo eziqinile nezingabizi kakhulu zokuthuthwa kwamanzi komasipala, kwezolimo nasezimbonini, okukhuthaza ukwakhiwa kwengqalasizinda yokugcina amanzi ezinzile.
Amapayipi aqoshiwe futhi ashiselwe akhiqizwa yi-Cangzhou Steel Mills ayisici esibalulekile sezinhlelo zamanzi angaphansi komhlaba. Amapayipi ashiselwe nge-arc angaphansi komhlaba e-S235 JR kanye ne-X70, anezakhiwo zawo ezinhle kakhulu zemishini kanye nokumelana nezici zemvelo, abalulekile ekuqinisekiseni ukuthuthwa kwamanzi okuphumelelayo. Uma sibheka phambili, ukubaluleka kwale mikhiqizo kuzoqhubeka nokukhula, kugqamisa isidingo semboni yamapayipi ensimbi sokukhiqiza okuseqophelweni eliphezulu kanye nezixazululo ezintsha.
