Izixhobo ze-Alweminium zolwakhiwo lwebhulorho zihamba kancinci, kwaye ikamva le-Aluminium Alloy Bridge ijongeka lithembisa

Iibhulorho ziyinto ebalulekileyo kwimbali yoluntu. Ukususela kumaxesha amandulo xa abantu babesebenzisa imithi kunye namatye aqaqambileyo ukuwela iindlela zamanzi kunye neentyatyambo, ekusebenziseni iibhulorho ze-arch, indaleko iphawuleka. Ukuvulwa kwakutshanje kweHong Kong-Zhuhai-Macao Bridge uphawula imbali ebalulekileyo kwimbali yeebhlorho. Kumilo lwebhulorho yale mihla, ukongeza ekusebenziseni izakhi zekhonkrithi, izixhobo zentsimbi, ngakumbi ulwakhiwo lwe-ALMINUM, lube lolona khetho lubalulekileyo ngenxa yezibonelelo zabo ezahlukeneyo.

Ngo-1933, i-Aluminium yokuqala ye-Allouy Bridge isetyenziselwa ibhulorho ibeka umlambo ePittsburgh eUnited States. Ngaphezu kweminyaka elishumi kamva, ngo-1949, eCanada wagqiba i-Aluminium ye-Aluminium Bridge Shide umlambo wase-Saguenay eQuebec, kunye nendawo enye efikelela kwi-88.4 yeemitha. Le bhulorho yayiyindawo yokuqala ye-Aluminium ye-Aluminium. Ibhulorho yayinee-piers malunga ne-15 yeemitha eziphakamileyo kunye neendlela ezimbini zendlela yokuhambahamba kwezithuthi. Isetyenziswe ngu-2014 Xa kuthelekiswa nebhulorho ecwangcisiweyo yaseStee, yanciphisa ubunzima malunga ne-56%.

Ukusukela ngoko, imeko ye-Aluminium allous Bridy yesakhiwo ayinakukwazi. Phakathi kwe-1949 nango-1985, i-United Kingdom eyakhiwe malunga ne-35 i-Aluminium Alloure Alloure, ngelixa iJamani yezakhiwe ngeenyawo ezingama-20 phakathi kwe-1950 nango-1950. Ulwakhiwo lweebhlorho ze-Aluminium ye-Aluminium yexesha elizayo.

Xa kuthelekiswa nentsimbi, izixhobo ze-Aluminium ze-Aluminium zinoxinaniso olusezantsi, zibetha kakhulu, ngama-34 kuphela omthwalo wensimbi yentsimbi yentsimbi. Nangona kunjalo, baneempawu zamandla ezifanayo zentsimbi. Ukongeza, ialuminium alloys ibonakalisa i-elasticy egqwesileyo kunye nokungaxhathisi i-corrosion ngelixa ineendleko eziphantsi zolondolozo. Ngenxa yoko, bafumene isicelo esikhulu kulwakhiwo lwebhulorho yale mihla.

I-China yenze inyathelo elibalulekileyo lokwakha ibhulorho. Ibhulorho yeZhaozhou, emi iminyaka engaphezu kwe-1500, yenye yeempumelelo ze-pidge zaseTshayina zamandulo. Kwixesha lanamhlanje, ngoncedo lwangaphambili lweSoviet Union, i-China yakha iibhulorho ezininzi zentsimbi, kubandakanya iibhlorho ze-YAngtHe kwi-nanjung kwi-nanjun kunye ne-wian, kunye ne-Pearl River eGuangzhou. Nangona kunjalo, ukusetyenziswa kweBridge Bridges e-China kubonakala ngathi kukulinganiselwe. Ibhulorho yokuqala ye-Aluminium Alfy e-China yayiyibhulorho yabahambi ngeenyawo kwi-qingzhou, eyakhiwe ngo-2007. Le bhuloge ifakwe kwaye ifakwe ngaphandle kweJamani ivela eJamani. Kwakuloo nyaka, ibhulorho yabahambi ngeenyawo e-Xujusiyai, uShanghai, waphuhliswa ngokupheleleyo kwaye wenziwa ngekhaya esebenzisa izakhiwo ze-aluminium. Ngokuyintloko isetyenziswa i-6061-T6 Aluminium Alloy kwaye, ngaphandle kwe-15-ton yobunzima, inokuxhasa umthwalo weetoni ezingama-50.

Kwixa elizayo, iibhulorho ze-Aluminium Alloy zinamathemba amakhulu ophuhliso e-China ngenxa yezizathu ezininzi:

I-1 ye-China ye-China e-China ePhezulu iyothusayo, ngakumbi kumanzi ahambahambayo emilabeni yasentshona ngeentlambo ezininzi kunye nemilambo. I-Aluminium Allow Bridges, ngenxa yokufumana lula izithuthi kunye neepropathi ezikhanyayo, kulindeleke ukuba zibe nentengiso ebalulekileyo.

2 Izixhobo zentsimbi zithambekele ekubeni zigqunywe kwaye zisebenza kakubi ngamaqondo obushushu asezantsi. I-Corrosion yentsimbi ichaphazela kakhulu uzinzo lwebhulorho, elikhokelela kwiindleko eziphezulu zokulungisa kunye neengozi zokhuseleko. Ngokwahlukileyo, izixhobo ze-Aluminium zinengxaki yokunganyangeki eqinileyo kwaye yenza kakuhle kumaqondo obushushu asezantsi, abenze balungele ukuqina kwexesha elide. Ngelixa iibhlorho ze-Aluminium Alloy zinokuba neendleko eziphakamileyo zokwakha, iindleko zabo zolondolozo eziphantsi zinokunceda ukunciphisa umsantsa weendleko ngokuhamba kwexesha.

3 Uphando kwiiphaneli ze-aluminium bridge, zombini ezendlwalweni kwaye kwilizwe liphela, ziphuhliswa kakuhle, kwaye ezi zixhobo zisetyenziswa ngokubanzi. Inkqubela phambili kuphando lwezinto ezibonakalayo ibonelela ngesiqinisekiso sobuchwephesha bokuphuhlisa izabelo ezitsha ezihlangabezana neemfuno zomsebenzi ezahlukeneyo. Chinese aluminum manufacturers, including industry giants like Liaoning Zhongwang, have gradually shifted their focus to industrial aluminum profiles, laying the foundation for aluminum alloy bridge construction.

4 Ulwakhiwo lwe-Right Ruley Hight kwiidolophu ezinkulu zaseTshayina zibeka iimfuno ezingqongqo zezakhiwo ezivela ngaphezulu komhlaba. Ngenxa yenzuzo yabo enkulu, kuyabonakala ukuba kuyabonakala ukuba uninzi lwe-allouy offrian kunye neebhulorho zendlela ziya kuyilwa kwaye zisetyenziswe kwixesha elizayo.
