Isakhiwo Sensimbi Esijwayelekile sase-Australia Ezentengiso Nezakhiwo Zokuhlala Complex EPC Construction

Izici zensimbi zingamandla aphezulu, isisindo esincane, ukuqina okuhle okuphelele, nokumelana okuqinile nokuguqulwa, ngakho-ke ifaneleka ngokukhethekile ukwakha izakhiwo ezinkulu, eziphakeme kakhulu, nezisinda kakhulu;impahla ine-homogeneity enhle ne-isotropy, futhi ilungele ukunwebeka Umzimba uhambisana kakhulu nokuqagela okuyisisekelo komshini wobunjiniyela ojwayelekile;impahla ine-plasticity enhle nokuqina, ingaba ne-deformation enkulu, futhi ingakwazi ukumelana nemithwalo enamandla;isikhathi sokwakha sifushane;idigri yayo yezimboni iphezulu, futhi ukukhiqizwa kochwepheshe okuneziqu zemishini ephezulu kungenziwa.

Isakhiwo sensimbi kufanele sifundwe ngensimbi ephezulu yamandla ukuze kwandiswe kakhulu amandla ayo okuvunwa;ngaphezu kwalokho, izinhlobo ezintsha zensimbi kufanele zigoqwe, njengensimbi emise okwe-H (eyaziwa nangokuthi insimbi ene-wide flange) nensimbi emise okwe-T namapuleti ensimbi anephrofayili, njll. Isidingo sezakhiwo eziphakeme kakhulu.

Ngaphezu kwalokho, kukhona uhlelo lwesakhiwo sensimbi esilula ngaphandle kwebhuloho lokushisa.Isakhiwo ngokwaso asiwongi amandla.Lobu buchwepheshe busebenzisa izixhumi ezikhethekile ezihlakaniphile ukuxazulula inkinga yamabhuloho abandayo futhi ashisayo esakhiweni.Isakhiwo esincane se-truss sivumela izintambo namapayipi amanzi ukuba adlule odongeni.Ukuhlobisa Ukwakhiwa kulula.

Ukusebenza:

1. Amandla:

Inkomba yamandla yensimbi yakhiwe ngomkhawulo wokunwebeka u-σe, umkhawulo wesivuno σy, kanye nomkhawulo we-tensile σu.Umklamo usekelwe emandleni okukhiqiza ensimbi.Amandla okukhiqiza aphezulu anganciphisa isisindo sesakhiwo, asindise insimbi, futhi anciphise izindleko.Amandla aqinile σu ingcindezi enkulu insimbi engamelana nayo ngaphambi kokwehluleka.Ngalesi sikhathi, isakhiwo silahlekelwa ukusebenza kwaso ngenxa yokuguqulwa okukhulu kwepulasitiki, kodwa isakhiwo asigogeki futhi asibhidliki, esihlangabezana nezidingo zesakhiwo sokumelana nokuzamazama komhlaba okungavamile.Ivelu ye-'Σu / σy ingathathwa njengepharamitha yendawo yokugcina amandla ensimbi.

2. Ipulasitiki:

I-plasticity yensimbi ngokuvamile ibhekisela empahleni yokuba ne-deformation ebalulekile yepulasitiki ngaphandle kokuphuka ngemva kokuba ingcindezi idlula iphuzu lokukhiqiza.Izinkomba eziyinhloko zokulinganisa ikhono lepulasitiki lokuguquguquka kwensimbi ukunwetshwa kuka-δ kanye nokuncipha kwesigaba ψ.

3. Ukusebenza kokugoba okubandayo:

Ukugoba okubandayo kwensimbi kuyisilinganiso sokumelana kwensimbi ekuqhekekeni lapho ukuguqulwa kwepulasitiki kwenzeka endaweni yokushisa.Ukusebenza kokugoba okubandayo kwensimbi ukusebenzisa isilingo sokugoba esibandayo ukuhlola ukusebenza kokugoba kokugoba kwensimbi ngaphansi kwezinga elishiwo lokugoba.

4. Ukuqina komthelela:

Ukuqina komthelela kwensimbi kusho ikhono lensimbi lokumunca amandla e-kinetic emishini ngesikhathi sokuphuka ngaphansi komthwalo womthelela.Kuyimpahla yemishini ekala ukumelana kwensimbi ukuze kube nomthelela womthwalo.Kungase kubangele ukuphuka okungama-brittle ngenxa yezinga lokushisa eliphansi nokugxilisa ingqondo yengcindezi.Inkomba yokuqina komthelela yensimbi ngokuvamile itholakala ngokuhlolwa komthelela kwezingcezu zokuhlola ezijwayelekile.

5. Ukusebenza kwe-Welding:

Ukusebenza kwe-welding yensimbi kubhekisela ekuhlanganiseni kwe-welding ngokusebenza okuhle ngaphansi kwezimo ezithile zenqubo ye-welding.Ukusebenza kwe-Welding kungahlukaniswa ngokusebenza kwe-welding kanye nokusebenza kwe-welding kunqubo ye-welding.Ukusebenza kwe-welding kunqubo yokushisela kubhekisela ekuthambekeni komthungo wokushisela kanye nensimbi eduze komthungo wokushisela ukuze kungabi nemifantu eshisayo noma imifantu enciphayo epholisayo ngesikhathi senqubo yokushisela.Ukusebenza kahle kokushisela kusho ukuthi ngaphansi kwezimo ezithile zenqubo yokushisela, insimbi yokushisela kanye nensimbi eyisisekelo eseduze ngeke iqhekeke.Ukusebenza kwe-welding ngokokusebenza kubhekisela kukuqina komthelela kanye nokudumba kwendawo ethinteke ekushiseni kumthungo wokushisela.I-China yamukela indlela yokuhlola ukusebenza kwe-welding enqubweni yokushisela, futhi yamukela indlela yokuhlola ukusebenza kwe-welding esimweni sokusebenziseka.

6. Ukuqina:

Kunezici eziningi ezithinta ukuqina kwensimbi.Esokuqala siwukumelana nokugqwala okungekuhle kwensimbi, futhi kufanele kuthathwe izinyathelo zokuvikela ukuvimbela ukugqwala kwensimbi nokugqwala.Izinyathelo zokuzivikela zihlanganisa: ukunakekelwa okuvamile kopende bensimbi, ukusetshenziswa kwezithako zensimbi, kanye nokusetshenziswa kwezinyathelo ezikhethekile zokuzivikela lapho kukhona imidiya egqwala eqinile njengama-asidi, ama-alkali, nosawoti.I-zinc ingot igxilile ejazini, futhi i-electrolyte yamanzi olwandle izogqwala ngokuzenzakalelayo ingot ye-zinc kuqala, ukuze kufezwe umsebenzi wokuvikela ibhantshi lensimbi.Okwesibili, ngenxa yokushisa okuphezulu nomthwalo wesikhathi eside, amandla okubhubhisa ensimbi aphansi kunalawo amandla esikhashana.Ngakho-ke, insimbi yesikhathi eside yokushisa okuphezulu kufanele ihlolwe amandla esikhathi eside.Insimbi izoba nzima ngokuzenzakalelayo futhi ibe brittle ngokuhamba kwesikhathi, okuyinto "yokuguga".Ukuqina komthelela wensimbi ngaphansi kwezinga lokushisa eliphansi kuzohlolwa.

Imikhiqizo yesakhiwo sensimbi yenkampani yethu ingahlangabezana namazinga ahlukahlukene aphesheya njengezinga lase-Australia, indinganiso yaseNew Zealand, indinganiso yaseBrithani kanye nezinga laseMelika.Siyakwamukela uphenyo lwakho.
