Kwizakhiwo zanamhlanje, ukuqina yeyona nto iphambili ekulinganiseni impumelelo okanye ukungaphumeleli kweprojekthi. Ukususela kwiingcango zeeBridges ezinqumla ulwandle ukuya kwimithambo yamandla egqunywe nzulu ngaphantsi komhlaba, ukhetho lwezinto zokwakha lumisela ngokuthe ngqo ukuba isakhiwo sinokumelana novavanyo lwexesha kunye nokusingqongileyo. Phakathi kwazo,Umbhobho wentsimbi odibeneyo ojikelezayo(ipayipi yentsimbi edibeneyo ejikelezayo) ibe yenye yeendlela zobuchwepheshe eziphambili zokuphucula ukuqina kweziseko zophuhliso ngenkqubo yayo yokuvelisa eyahlukileyo kunye nokusebenza kakuhle kwesakhiwo. Eli nqaku liza kuhlola indlela iipayipi ezidibeneyo ezijikelezayo ezinokuba negalelo ngayo kubunjineli banamhlanje obuqinileyo nobuhlala ixesha elide.
Inzuzo Engundoqo: Inkqubo yokujikeleza ifikelela njani ekuqineni okumangalisayo
Ukuqina okugqwesileyoUmbhobho odibeneyo ojikelezayoisekelwe kumgaqo wayo wokuvelisa oguqukayo. Ngokungafaniyo nemibhobho yendabuko edibeneyo yomthungo othe tye, imibhobho edibeneyo ejikelezayo yenziwa ngokuqengqa imicu yentsimbi eyakhiweyo enekhabhoni ephantsi ibe ziindawo ezingenanto zemibhobho kwii-engile ezithile ezijikelezayo uze udibanise imithungo yemibhobho. Olu tshintsho lubonakala lulula kwi-Angle luzise utshintsho olukhulu ekusebenzeni kobunjineli:
Ukusasazwa koxinzelelo olufanayo kunye nokumelana okunamandla kokucinezela kunye nokuguquguquka: I-spiral weld isasaza uxinzelelo lwangaphakathi nolwangaphandle oluthwalwa ludonga lombhobho kwicala lokujika, ithintela ukugxila koxinzelelo. Oku kwenza umbhobho ubonise ukuqina okuphezulu kunye nokuxhathisa ukuguquguquka xa uphantsi koxinzelelo oluphezulu, umthwalo onzima, kunye nokumiswa kwesiseko.
Ukuqhubeka kakuhle kwesakhiwo kunye nobomi obude bokudinwa: Isakhiwo esijikelezayo esiqhubekayo sisusa amakhonkco abuthathaka ee-seams ezithe tye ezinqamlezileyo emzimbeni wepayipi. Xa siphantsi kwemithwalo ejikelezayo (efana nokungcangcazela kwesithuthi, impembelelo yamaza, ukuguquguquka koxinzelelo), sinokuthintela ngempumelelo ukuqaliswa nokusasazeka kweentanda, nto leyo eyandisa ubomi benkonzo.
Ububanzi obuguquguqukayo, obunokuhlengahlengiswa kwiimfuno zobunjineli ezintsonkothileyo: Inkqubo yokwenza i-spiral inokuvelisa ngokulula imibhobho yentsimbi enobubanzi obukhulu, enodonga oluqinileyo, nto leyo kanye ifunwa yiprojekthi yeziseko ezinkulu, njengeziseko zeenqwaba zolwandle olunzulu, ii-culvert ezinkulu, kunye nemibhobho ephambili yokuhambisa amanzi, ngokungxamisekileyo.
Iimveliso zochungechunge lweMibhobho yentsimbi yeSpiral Welded Carbon Steel Pipe esiziqalisileyo zimela kakuhle obu buchwepheshe buphambili. Umbhobho ngamnye wentsimbi wenziwe ngokuchanekileyo kwaye wenziwe ukuze unike amandla angenakuthelekiswa nanto, ukuqina kunye nokuguquguquka, uhlangabezana nazo zonke iimfuno ezifunekayo ukusuka kuthungelwano lwemibhobho engaphantsi komhlaba ukuya kwisakhelo sezakhiwo eziphakamileyo eziphezulu ezingaphezulu komhlaba.
Imeko yesicelo: Ukubonakaliswa kokuqina kwiziseko ezibalulekileyo
Iimpawu zokuqina kwemibhobho yentsimbi edibeneyo ejikelezayo zidlala indima engenakutshintshwa kwiindawo ezininzi zeziseko zophuhliso eziphambili:
Iziseko zothutho: Isiseko seenqwaba kunye ne-pier casing ezisetyenziselwa iiBridges, kunye namandla azo okuxinzelela kunye nokumelana namandla asecaleni, ziqinisekisa uzinzo lwesakhiwo kangangeminyaka elikhulu.
Ulondolozo lwamanzi kunye nobunjineli bukamasipala: Njengemijelo emikhulu yokuhambisa amanzi kunye nemibhobho yokulawula izikhukula kunye nemibhobho yokukhupha amanzi, ukusebenza kwayo okugqwesileyo ekuthwaleni uxinzelelo kunye nokulwa nokugqwala (ingakumbi emva kokulungiswa kwengubo) kuqinisekisa ukhuseleko lokunikezelwa kwamanzi kunye nokuqina kwezixeko.
Ukuhanjiswa kwamandla: Isetyenziswa kwimibhobho yokuhambisa ioyile negesi. Ukusasazwa kwayo koxinzelelo olufanayo kunye nokuqina okuhle kunokumelana ngokukhuselekileyo nentshukumo yokwakheka kunye noxinzelelo oluphezulu lwangaphakathi, kwaye lilitye lesiseko lokusebenza ngokukhuselekileyo kwexesha elide kwemithambo yamandla.
Ubunjineli bemizi-mveliso nolwandle: Ekwakhiweni kwezikhululo zezibuko kunye namaqonga aselunxwemeni, isetyenziswa njengekholamu yokuxhasa ephambili kunye nejakethi, kwaye ukumelana kwayo nokudinwa kunye nokunganyamezelani nokugqwala kwamanzi olwandle kubaluleke kakhulu.
Uqinisekiso loMgangatho: Ukuzinikela kwabavelisi abaphambili kushishino
Njengomvelisi ophambili weepayipi zeSpiral Steel kunye neemveliso zokugquma iipayipi eTshayina, iCangzhou Spiral Steel Pipe Group Co., Ltd. ibisoloko izibophelele ekunikezeleni iipayipi zentsimbi ezidibeneyo zeSpiral ezithembekileyo kubathengi behlabathi. Ukusukela oko yasekwa ngo-1993, inkampani ibisoloko ibandakanyeka kakhulu kwicandelo leepayipi zentsimbi ezijikelezayo. Umzi-mveliso wayo ukwiSixeko saseCangzhou, kwiPhondo laseHebei, ugubungela indawo yeemitha zesikwere ezingama-350,000, kunye neempahla zizonke ezizizigidi ezingama-680 zeeyuan kunye nabasebenzi abangama-680.
Sinamandla amakhulu okuvelisa imveliso, kunye nemveliso yonyaka yeetoni ezingama-400,000 zeepayipi zentsimbi ezijikelezayo kunye nexabiso lonyaka lemveliso eliyi-1.8 yeebhiliyoni zeeyuan. Ukuqokelelana okuqinileyo kobuchwephesha, ulawulo oluqinileyo lomgangatho olupheleleyo kunye nophuhliso oluqhubekayo lobuchwepheshe kuqinisekisa ukuba yonke iPipe eWelded yeSpiral esiyivelisayo ayifikeleli nje kuphela kwimigangatho, kodwa ikwadlula nolindelo olulinganiselweyo lokuqina kwezinto kwiiprojekthi ezininzi zeziseko zophuhliso.
Lilonke, i-Spiral Welded Steel Pipe ayisiyo nje ipayipi yentsimbi, kodwa ikwayisisombululo sokuqina esiqinisekisiweyo ngobunjineli. Ulwakhiwo lwayo oluyi-helical olukhethekileyo yikristale
