Okushisayo - Umucu Wensimbi Ocwilisiwe Ocindezelwe
Isingeniso Somkhiqizo
I-Hot-Dipped Galvanized PC Strand yensimbi ephumuzayo esezingeni eliphansi eyenziwe ngensimbi eyisikhombisa eshisiwe eyindilinga eshisiwe enokumelana nokugqwala okuhle, okunganweba ngempumelelo impilo yezingxenye esimweni sendawo egqwalile njengezindawo ezisogwini, eziqashelwa njenge. indlela ephumelelayo yokuvimbela ukugqwala okwamanje nakwamanye amazwe.
Leli zinga lisebenza kukhebula lebhuloho, izingxenye eziqinile eziqinile, ukuphakamisa noma ukulungisa izingxenye ezishubile zezakhiwo nezinye izakhiwo ezicindezelwe ngaphambili, ezingasetshenziswa ngokuqondile ekwakhiweni kwe-grouting kakhonkolo, ububanzi: 12.7mm, 15.mm, 15.7mm, 17.8mm, amandla iklasi: 1770MPa, 1860 MPa, 1960MPa. (ngemuva kwalokhu kuthiwa "umucu wensimbi").
Isakhiwo semikhiqizo engu-1x7, 1x19 ecwiliswe uthayela wensimbi eshisiwe, amandla aqinile angafinyelela ku-1860MPa kanye nokucaciswa okufanayo njenge-plain&round PC steel strand ngokwamazinga okusebenza acc.to GB/T 33363, ASTM A416, EN101896, BS5 kanye ne-NFA35-035 njll.
Izici Zomkhiqizo
Umkhiqizo ungakhiqizwa ngokwezicelo ze-zinc enamathela kumakhasimende, i-zinc enamathela ingafinyelela ku-250 gsm noma ngaphezulu, ukufana kwe-zinc enamathela ungqimba izikhathi ezingu-3-4 ngaphandle kokudalula ithusi, futhi ukunamathela akuphuli futhi akuhliki. ngaphansi kwesimo ngokusonta imibuthano engu-8 ngemva kokufakwa kwezinki.
Ngokuya ngemishini ethuthukisiwe yenkampani, singakwazi ukuklama inqubo yama-galvanized ukuhlangabezana nezidingo ezikhethekile zabasebenzisi ngekhwalithi ye-zinc layer, ikhwalithi yendawo, njll.
Uma kuqhathaniswa ne-PC steel strand ngaphandle kokumbozwa kanye nomucu wensimbi we-PC, owokuqala ubonakale ukugqwala okubomvu ngemuva kokuhlolwa kwesifutho sikasawoti amahora angama-24.
Izinguquko zesampula ze-PC steel strand ngaphandle kokumbozwa kanye nentambo yensimbi ye-PC ngemuva kwezinsuku ezingama-21 zokuhlolwa kwesifutho sikasawoti esingathathi hlangothi kanje,
Izicelo Zomkhiqizo
1) Imikhiqizo ingasetshenziswa kubunjiniyela bokwakha kanye nobunjiniyela bokwesekwa komgwaqo wezimayini zamalahle ngaphansi kwezimo zemvelo ezinzima.
2) Eminyakeni yamuva nje, isetshenziswe nasemkhakheni wamandla omoya. "1x7-medium 21.6mm, Large-Sized Hot-Dipped Galvanized Galvanized PC Steel Strand", esetshenziswe kumbhoshongo wokuqala we-"160m, umoya ophansi wesivinini esiphansi somoya", onamandla okuthwala aphezulu, osebenza kahle ukuze uthuthuke. ukumelana nomoya wombhoshongo. Ngokumelana nokugqwala okuhle, okunganweba impilo yesevisi yombhoshongo.
Umbhoshongo wokuqala emhlabeni wokuhlola isivinini somoya ophansi ongu-160m eShandong
