Ipayipi Lokufaka Ububanzi Obukhulu Eliphezulu Elisezingeni Eliphezulu

Incazelo emfushane:

Njengoba iklanyelwe ukumelana nobunzima bokwakhiwa okunzima, amapayipi ethu okufaka izintambo asezingeni eliphezulu, anobubanzi obukhulu anikeza amandla nokuqina okudingekayo ekusekelweni kwesisekelo. Ubuchwepheshe bokushisela obujikelezayo obusetshenziswa enkambisweni yethu yokukhiqiza buqinisekisa isakhiwo esingenamthungo nesiqinile, bunciphisa ingozi yokwehluleka futhi bukhulise isikhathi senkonzo.

Amathegi Omkhiqizo

Sethula amapayipi okufaka izinsimbi ezinkulu asezingeni eliphezulu, okuyisisombululo esifanele sokuhlangabezana nezidingo ezihlala zishintsha zokwakhiwa kanye nokuthuthukiswa kwengqalasizinda. Njengoba imboni ibona ukwanda okukhulu kosayizi wamapayipi okufaka izinsimbi, isidingo sezinto eziqinile nezithembekile asikaze sibe sikhulu kangaka. Amapayipi ethu ensimbi ahlanganiswe nge-spiral ahlanganiswe nge-large diameter aklanyelwe ukubhekana nalezi zinselele, ukuqinisekisa ukusebenza okuphezulu kanye nokuqina kwezicelo ezahlukahlukene.

Yakhelwe ukumelana nobunzima bokwakhiwa okunzima, ikhwalithi yethu ephezulu,amapayipi okuhlanganisa ubukhulu obukhuluinikeza amandla nokuqina okudingekayo ekusekelweni kwesisekelo. Ubuchwepheshe bokushisela obujikelezayo obusetshenziswa enqubweni yethu yokukhiqiza buqinisekisa isakhiwo esingenamthungo nesiqinile, bunciphisa ingozi yokwehluleka futhi bukhulisa isikhathi senkonzo. Kungakhathaliseki ukuthi uhilelekile kumaphrojekthi ezentengiselwano, ezindawo zokuhlala noma engqalasizinda, amapayipi ethu okufaka izintambo ayisinqumo esifanele sokuhlangabezana nezidingo zakho.

Inzuzo yomkhiqizo

Enye yezinzuzo eziyinhloko zokusebenzisa amapayipi okufaka inqwaba anobubanzi obukhulu yikhono lawo lokubekezelela imithwalo esindayo. Lawa mapayipi aklanyelwe ukumelana nengcindezi enkulu, okwenza afaneleke kakhulu ekusetshenzisweni kwesisekelo esijulile kumaphrojekthi amakhulu okwakha. Ububanzi bawo obukhulu bukhulisa nokufuduka kwenhlabathi, ngaleyo ndlela kuthuthukisa ukuzinza futhi kunciphise izinkinga zokuhlala. Ngaphezu kwalokho, inqubo yokushisela ejikelezayo esetshenziswa ekwenziweni kwalawa mapayipi iqinisekisa isibopho esiqinile nesihlala isikhathi eside, inciphisa ingozi yokwehluleka kwesakhiwo.

Ukushoda Komkhiqizo

Izindleko zokukhiqiza ipayipi lokufaka izintambo elinobubanzi obukhulu elisezingeni eliphezulu zingaba phezulu kunezinketho zendabuko, okungathinta isabelomali sephrojekthi.

Ngaphezu kwalokho, inqubo yokufaka ingaba yinkimbinkimbi kakhulu futhi idle isikhathi, idinga imishini ekhethekile kanye nabasebenzi abanamakhono. Uma ingaphathwa kahle, lokhu kungabangela ukubambezeleka kwezikhathi zephrojekthi.

Isicelo

Ezweni elikhula njalo lokwakhiwa nokuthuthukiswa kwengqalasizinda, isidingo sezinto eziqinile sibaluleke kakhulu. Enye yezinto eziye zathola ukunakwa okukhulu yipayipi lokufaka izintambo elisezingeni eliphezulu, elinobubanzi obukhulu. Njengoba amaphrojekthi okwakha ekhula ngobukhulu kanye nobunzima, isidingo sezixazululo zokufaka izintambo ezinkulu nezihlala isikhathi eside siba yinto ebaluleke kakhulu.

Njengoba kuthuthuka ngokushesha amaphrojekthi okwakha amadolobha kanye nengqalasizinda, ububanzi bamapayipi okufaka izintambo buyaqhubeka nokukhula ukuze kuhlangatshezwane nezidingo zobunjiniyela besimanje. Kuhlanganiswe nge-spiral weld esezingeni eliphezulu.ipayipi lensimbi elinobubanzi obukhuluIzinqwaba zibalulekile ukuze kuhlinzekwe ukwesekwa nokuqina okudingekayo kwezakhiwo ezahlukene ezifana namabhuloho, izakhiwo kanye nezindawo zasolwandle. Lawa mapayipi aklanyelwe ukumelana nemithwalo emikhulu kanye nezimo zemvelo ezinzima, okuqinisekisa ukuthi amaphrojekthi abawasekelayo ahlala isikhathi eside futhi aphephile.

Njengoba imboni yokwakha iqhubeka nokukhula, ukubaluleka kwepayipi lokufaka ungqimba olukhulu olusezingeni eliphezulu akunakugcizelelwa ngokweqile. Ukuzibophezela kwethu ekhwalithini nasekusunguleni izinto ezintsha kuqinisekisa ukuthi sihlala singabalingani abathembekile embonini yokwakha, sihlinzeka ngezinto ezibalulekile ezidingekayo engqalasizinda yesikhathi esizayo. Kungakhathaliseki ukuthi uhilelekile kuphrojekthi enkulu noma iphrojekthi encane yokwakha, amapayipi ethu okufaka ungqimba olukhulu akunikeza amandla nokuthembeka okudingayo.

Imibuzo Evame Ukubuzwa

Q1: Iyini ipayipi lokufaka inqwaba yobubanzi obukhulu?

Amapayipi amakhulu okufaka izinsimbi ayizakhiwo ezisilinda ezisetshenziselwa ukusekela imithwalo esindayo kumaphrojekthi okwakha. Ububanzi bawo obukhulayo bunikeza amandla amakhulu okuthwala umthwalo futhi afanelekela izisekelo ezijulile ezimweni zenhlabathi ezinzima.

Q2: Kungani ukhethe izinqwaba zamapayipi ensimbi ahlanganisiwe nge-spiral?

Izinqwaba zamapayipi ensimbi ahlanganisiwe ajikelezayo aziwa ngamandla awo aphezulu kanye nokuqina kwawo. Inqubo yokushisela ejikelezayo iqinisekisa umthungo oqhubekayo, othuthukisa ubuqotho besakhiwo sepayipi. Le ndlela ivumela futhi ukukhiqizwa kwamapayipi ensimbi amakhulu ukuze kuhlangatshezwane nezidingo ezikhulayo zokwakha zanamuhla.

Umbuzo 3: La mapayipi enziwa kuphi?

Amapayipi ethu okufaka izintambo ezinkulu asezingeni eliphezulu akhiqizwa eCangzhou, eSifundazweni saseHebei. Ifektri yethu yasungulwa ngo-1993 futhi ihlanganisa indawo engamamitha-skwele angu-350,000 enempahla elinganiselwa ku-RMB 680 million. Sinabasebenzi abangu-680 abazinikele ekukhiqizeni izixazululo zokufaka izintambo ezisezingeni eliphezulu ezihlangabezana nezidingo eziqinile zemboni yokwakha.
