I-Flat Stressing Anchorage/Izikhonkwane zokucindezeleka zendiza
Isingeniso
Izikhonkwane zokucindezeleka kwendiza/I-Flat Stressing Anchorage zisetshenziswa ekwakhiweni kukakhonkolo ocindezelwe ngaphambili ukuze kumiswe futhi kudluliselwe ukucindezelwa kwamabha ensimbi anamandla aphezulu kukhonkolo ezungezile. Amasistimu okunamathisela ukucindezeleka kwendiza ngokuvamile ahlanganisa izingxenye eziningi, okuhlanganisa okulandelayo:
I-Bearing Slab: Ipuleti eliyisicaba elisabalalisa ukucindezeleka kwemisipha kukhonkolo.
Ama-Wedges: Asetshenziselwa ukubopha imicu yensimbi ene-prestressed noma izintambo ukuze kudluliselwe ingcindezi kuma-slabs athwala umthwalo kanye nokhonkolo.
Amapayipi: Amapayipi okuzivikela asetshenziselwa ukugoqa imisipha egxilile futhi ivikeleke ekugqwaleni nasekulimaleni.
I-Anchor Yokuqeda: Le ngxenye ibambelela ngokuvikelekile i-tendon ecindezelayo ekugcineni kwesakhiwo.
Ama-Deflectors: Kwezinye izinhlelo, ama-deflectors asetshenziselwa ukushintsha isiqondiso se-tendon, okuvumela ukudluliswa kokucindezeleka okuphumelelayo. Amahange okucindezeleka kwendiza adlala indima ebalulekile ekusebenzeni nasekuqineni kwezakhiwo zekhonkrithi ezicindezelwe ngaphambili, ukuqinisekisa ukuthi i-prestress idluliselwa ngokuphumelelayo kukhonkolo futhi ithuthukise umthamo wokuthwala umthwalo kanye nokumelana nokuqhekeka kokhonkolo.
Izici
Lawa mahange kufanele aklanywe kahle futhi afakwe ukuze kuqinisekiswe ubuqotho bohlelo lukakhonkolo olucindezelwe ngaphambili futhi luhambisane namazinga nemithetho yemboni yokuphepha nokusebenza. Amahange okucindezeleka kwendiza/I-Flat Stressing Anchorage ayatholakala ekucushweni okuhlukene, njengamahange anomucu owodwa webha yensimbi eyodwa kanye namahange anemicu eminingi kumabha amaningi. Zibalulekile ekuqinisekiseni ukudluliswa okusebenzayo kwe-prestress kukhonkolo, ukuhlinzeka ngobuqotho besakhiwo obudingekayo kuhlelo lokusebenza.
Lawa mahange aklanywe futhi avivinywa ukuze ahlangabezane namazinga athile futhi aqinisekise ukuphepha nokuthembeka kwezinto zikakhonkolo ezigcizelelwe ngaphambili.
Izinhlelo zokusebenza
Ukusetshenziswa kwamahange okucindezeleka kwendiza kubalulekile ekwakhiweni kwezakhiwo ezihlukahlukene njengamabhuloho, izakhiwo nezindawo zokupaka, lapho kusetshenziswa khona ukhonkolo ogcizelelwe ngaphambili ukuze kuthuthukiswe ukusebenza kwesakhiwo kanye nokuqina kwezinto zikakhonkolo. Lawa mahange aklanywe futhi avivinywa ukuze ahlangabezane namazinga athile futhi aqinisekise ukuphepha nokuthembeka kwezinto zikakhonkolo ezigcizelelwe ngaphambili.
