Kwicandelo elihlala livela lobunjineli bokwakha, imfuno yemathiriyeli eyomeleleyo kunye neziguquguqukayo ibalulekile. Phakathi kwezi zixhobo,imfumba yentsimbi yombhobhoziye zaba sisiseko senkqubo yokwakha yale mihla. Ngokuthe ngqo, i-X42 SSAW (i-spiral submerged arc welded) iimfumba zemibhobho yentsimbi zibonwa ngenxa yokuguquguquka kwazo kunye nokusebenza olomeleleyo, ngakumbi kwiindawo ezinomngeni.
Amandla eemfumba zemibhobho yentsimbi
Iimfumba zemibhobho yentsimbi ziyilelwe ukubonelela ngenkxaso egqwesileyo kwiiprojekthi ezahlukeneyo zokwakha, kubandakanywa iibhulorho, izakhiwo kwaye ngokukodwa iidokhi kunye nezibonelelo zezibuko. I-X42 SSAW iimfumba zemibhobho yensimbi eziveliswe kwisiXeko saseCangzhou, kwiPhondo laseHebei zenziwe ngetsimbi ekumgangatho ophezulu wokuqinisekisa ubomi benkonzo kunye nokomelela nakwiimeko ezinzima. Uyilo lwayo oludityanisiweyo oludityanisiweyo alonyusi nje amandla kuphela kodwa lukwanokuthembeka, luyenze ibe lolona khetho lubalaseleyo lokuxhasa isiseko.
Inkqubo ekhethekileyo ye-spiral welding esetyenziswa kwimveliso yeX42 SSAW umbhobhoivumela i-welding eqhubekayo, ukuphucula kakhulu ukunyaniseka kwesakhiwo seemfumba. Olu phawu loyilo luluncedo ngakumbi kwizicelo apho iimfumba ziphantsi kwemithwalo esecaleni, efana nezo zifumaneka kwiindawo zaselwandle. Ukukwazi ukumelana nemikhosi enjalo kwenza ezi mfumba zibe yimathiriyeli eyimfuneko kwidokhi kunye nolwakhiwo lwezibuko, apho uzinzo lubalulekile.
Ukuguquguquka kwezakhiwo
Ukuguquguquka kweemfumba zemibhobho yensimbi kudlulela ngaphaya kwendima yabo ephambili njengenkxaso yesiseko. Zingasetyenziswa kwiinkqubo ezahlukeneyo ezibandakanya:
1. Ulwakhiwo lwaseLwandle: Njengoko kukhankanyiwe ngasentla, iimfumba zemibhobho yentsimbi ye-X42 SSAW zilungele ukwakhiwa kwedokhi kunye nezibuko. Ukunganyangeki kwe-corrosion yabo kunye nokukwazi ukumelana nemithwalo enzima kubenza bafanelekele ukuxhasa ii-piers zebhulorho, ii-piers kunye nezinye izakhiwo zaselwandle.
2. Iibhulorho kunye ne-Overpasses: Amandla kunye nokuqina kweemfumba zepayipi zensimbi zivumela ukuba zisetyenziswe kwiziseko zebhulorho ukubonelela ngenkxaso efunekayo kwimithwalo enzima yezithuthi kunye nokuqinisekisa ubomi benkonzo yesakhiwo.
3. Inkqubo yokugcina umhlaba:Umbhobho wentsimbiiingqumba zingasetyenziswa kwiinkqubo zokugcina umhlaba ukunceda ukuzinzisa umhlaba kunye nokuthintela ukhukuliseko, ngakumbi kwiindawo ezithanda ukukhukuliseka okanye izikhukhula.
4. IiProjekthi zomoya kunye neSolar: Ngokunyuka kweeprojekthi zamandla avuselelekayo, imfumba yepayipi yensimbi isetyenziselwa ngakumbi ukuxhasa ukufakwa kwee-injini zomoya kunye neepaneli zelanga, ukubonelela ngesiseko esizinzile kwiindawo ezahlukeneyo.
Ilifa elisemgangathweni
Yasekwa ngo-1993, inkampani ivelisa i-X42 spiral submerged arc welded steel pipe piles kwaye ibe yinkokeli yoshishino. Inkampani ithatha indawo ye-350,000 square metres, inee-asethi ezizizigidi ezingama-680 zeeyuan, kwaye inabasebenzi abanezakhono abangama-680, abazibophelele ekuveliseni iimveliso zentsimbi ezikumgangatho ophezulu. Ukusuka ekufumaneni izinto ezikrwada ukuya ekuhlolweni kokugqibela kweemveliso ezigqityiweyo, ukuzibophelela kwazo ekugqweseni kubonakala kuyo yonke inkalo yokusebenza kwazo.
ukuququmbela
Njengoko ulwakhiwo luqhubeka nokuguquka, ukuguquguquka kweemfumba zemibhobho yentsimbi, ngakumbi iimfumba zemibhobho yentsimbi ye-X42 SSAW, ziya kudlala indima ebalulekileyo ekubumbeni ikamva lophuhliso lweziseko ezingundoqo. Amandla abo, ukuqina kunye nokuguquguquka kwezinto ezininzi kubenza babe yinxalenye ebalulekileyo kwizicelo ezininzi, ukusuka kwizakhiwo zaselwandle ukuya kwiiprojekthi zamandla avuselelekayo. Ngesiseko esomeleleyo esakhiwe kumgangatho kunye nezinto ezintsha, inkampani yaseCangzhou ilungele ukuhlangabezana neemfuno ezikhulayo zoshishino lokwakha, ukuqinisekisa ukuba iimfumba zemibhobho yensimbi zihlala zingumthombo obalulekileyo kwiinjineli kunye nabakhi.
