Ukusetshenziswa kwe-prestressed pc steel wire kubunjiniyela bokwakha, ingabe uyazi ngakho?

Ukukhethwa kwezinto kudlala indima ebalulekile lapho kwakhiwa isakhiwo esiqinile nesihlala isikhathi eside.Ucingo lukakhonkolo olucindezelwe, oluvame ukwaziwa ngokuthiPC steel wirenoma i-prestressed steel wire, isibe ingxenye ebalulekile esetshenziswa ochwepheshe bezokwakha emhlabeni jikelele.Amandla ayo angavamile nokuvumelana nezimo kuyenza ibe yisixazululo sokuzikhethela konjiniyela abahlose ukwakha izakhiwo ezikwazi ukumelana nemithwalo esindayo, izimo zezulu ezimbi kakhulu kanye nokuhlolwa kwesikhathi.Kulesi sihloko, sizobheka kabanzi izinhlelo zokusebenza eziningi zei-prestressed steel concrete wireemisebenzini yokwakha.
Intambo kakhonkolo ecindezelwe, ngokuvamile i-4 mm ububanzi, ithatha indawo ebalulekile ku-arsenal yezinto zokwakha.Idizayini yayo enezimbambo eyingqayizivele ithuthukisa amandla okubopha phakathi kwentambo yensimbi nokhonkolo, ikhulise umthamo wesakhiwo wokuthwala umthwalo.Le phethini yokubamba iphinde isize ukusabalalisa ingcindezi ngokulinganayo kuyo yonke intambo, iqinisekisa ukusebenza okuphezulu.
Enye yezinhlelo zokusebenza eziyinhloko zei-prestressed steel concrete wireingaphakathi kwezakhi zikakhonkolo.Ukhonkolo we-Precast unikeza izinzuzo eziningi ngokuhlinzeka ngendawo yokukhiqiza elawulwayo ukukhiqiza izakhi zekhwalithi ephezulu.Abakhiqizi bezintambo ezinengcindezi babeka kahle intambo egxilile ngaphakathi kwamalungu okhonkolo asakazwa ngaphambili njengemishayo, amakholomu, nama-slabs ukuze aqinise.Lobu buchwepheshe bukhulisa kakhulu umthamo wokuthwala walezi zakhi kuyilapho kunciphisa ubukhulu bazo bubonke.
Ngaphezu kwalokho,i-prestressing wireasetshenziswa kakhulu ekwakhiweni kwamabhuloho nama-viaducts.Ngenxa yethrafikhi eningi kanye nokuchayeka kumandla emvelo, lezi zakhiwo zidinga amandla angavamile nokuqina.Ngokuhlanganisa i-spiral pc steel wire ngesikhathi sokwakha, onjiniyela bangandisa amandla nokuqina kwesakhiwo, bavimbele izingozi ezingaba khona futhi balule impilo yayo yesevisi.

Ukusetshenziswa kwespiral PC steel wirekumaphrojekthi wokwakha awanakuzitshwa.KuvunguzaPC wire 4mmisetshenziselwa ukukhiqiza amapayipi kakhonkolo, izigxobo, namathange okugcina angaphansi komhlaba.Ukwakheka kwayo okuzungezayo okuyingqayizivele kuyivumela ukuthi imelane namandla aqinile aqinile, okuvumela ukudalwa okungenamthungo kwezakhiwo ezingamacylindrical.Izakhiwo zemvelo zocingo lwe-PC oluvunguzayo kuhlanganiswe nokuguquguquka kwayo okukhethekile ziyenza ilungele ukukhiqiza amapayipi kakhonkolo ahlala isikhathi eside futhi amelana nokugqwala kanye nezingxenye ezifanayo zesilinda.
Ngamafuphi, ukuguquguquka kwezintambo zensimbi zikakhonkolo ezicindezelwe ngaphambili ezinhlotsheni zezinhlelo zokwakha azinakuqhathaniswa.Kungakhathaliseki ukuthi isetshenziswa kuma-elementi e-precast, ukwakhiwa kwebhuloho noma amapayipi kakhonkolo, amandla alo amangalisayo, ukuguquguquka okuguquguqukayo namandla ebhondi athuthukisiwe kusiza ukudala izakhiwo eziqinile nezihlala isikhathi eside.Ochwepheshe bezokwakha emhlabeni wonke bathembele kuyoi-prestressed steel wireukuqinisekisa ukuthi amaphrojekthi abo ahlangabezana nezindinganiso eziphakeme kakhulu zokuphepha nokuhlala isikhathi eside.
