Izingubo zethu eziningi zifaka ubuhlalu obuhle emikhonweni

Isingeniso sephrojekthi

• Inkampani yethu ikakhulukazi ihlinzeka ngemicu yensimbi egxilile ukuze kwakhiwe ngaphambili amabhuloho kakhonkolo kanye nezintambo zokuhlala zemibhoshongo emifushane yebhuloho elihlala ngekhebula kule phrojekthi.
  1. I-superstructure yebhuloho eliyinhloko isesimweni sebhinca lebhokisi lebhokisi eliguquguqukayo eline-prestressed, ububanzi bebhuloho elikhulu ngamamitha angu-33.5. Ibhuloho lokusondela lakhiwe ngama-slats, anobubanzi obubodwa obungamamitha ayi-12.5, ibhuloho lokusondela lamukela isakhiwo sebhande lebhokisi elincane elingamamitha angama-30. Kunamagida amabhokisi amancane angama-96 ku-30-metres Lile River Bridge, futhi isisindo sokuphakamisa ibhokisi elilodwa singamathani ayi-100.

• 2. Ikhebula elihlala ikhebula lenziwe nge-15-91 epoxy sprayed strand enokuvikelwa kwe-HDPE enezendlalelo ezimbili, umucu owodwa ububanziφ15.2mm, amandla aqinile fpk=1860MPa. (inani elijwayelekile)
  3. Izakhiwo zemishini yazo zonke izintambo zensimbi ezicindezelwe ngaphambili ezisetshenziswe kuphrojekthi zihambisana nezinhlinzeko ze-"Steel Strands for Prestressed Concrete"(GB/T5224-2014) kanye ne-EN10138-3:2009, izakhiwo zabo zokulwa nokugqwala zihlangabezana nezidingo ze-ASTM. I-A882/A882M-02a kanye ne-ISO 14655:1999. Ukumelana nokukhathala kwekhebula elihlala ikhebula kufanele kuhlangabezane nomkhawulo ophezulu wengcindezi σmax =0.45fptk, amplitude yengcindezi engu-200MPa, kanye nezinga lokuphuka kwentambo elingu-≤2% ngemva kwemijikelezo eyizigidi ezingu-2.

Imikhiqizo inenzuzo

• I-1.Izintambo zekhonkrithi ezicindezelweyo (PC) zivame ukusetshenziswa ekwakhiweni kwemishayo yekhonkrithi ukuze kunikeze amandla aqinile nokuqinisa.
  I-2.Le micu ivame ukugxilwa ngaphambili noma i-post-tensioned ngaphakathi kwekhonkrithi ukuze kwandiswe umthamo wokuthwala umthwalo nokunciphisa ukuqhekeka.
  3.Ukusetshenziswa kwezintambo ze-PC kusiza ukuthuthukisa ukusebenza kwesakhiwo jikelele kanye nokuqina kwemishayo kakhonkolo. Izintambo zikakhonkolo ezicindezelwe (PC) zivame ukusetshenziswa ekwakhiweni kwemishayo kakhonkolo ukuze kunikeze amandla aqinile nokuqinisa.
