Ukuqwalaselwa koFakelo loMgangatho eBusika

Ubusika buyeza, nangona kunjalo uninzi lweeprojekthi zokwakha zisaqhuba.Nangona kunjalo uyazazi iimeko zofakelo lomgangatho wePVC ebusika?Kufuneka kubekho amanqaku abalulekileyo, ngaphandle koko akufanelekanga ukufakela.
Ubushushu bomoya: ≥18℃
Ukufuma komoya: 40～65％
Ubushushu bomphezulu: ≥15℃
Iziqulatho zokufuma kwinqanaba elisisiseko:
≤3.5% (fine?aggregate?concrete)
≤2% (isamente?udaka)
≤1.8% (Umgangatho wokufudumeza)

Kukho izizathu zokwakhiwa kakubi:
1) Umgangatho ongaphantsi umanzi kakhulu, kwaye awomi ngokwaneleyo
I-2) Ubushushu buphantsi, kwaye izinto azikwazi ukuncamathelisa ngokusondeleyo kumgangatho ophantsi.
3) Iphenjelelwa liqondo lobushushu, isantya sokuncamathela sicotha
4) Emva kofakelo, ngenxa yokuhluka kweqondo lokushisa ebusuku, kulula ukuqiniswa okanye ukuthambisa.
5) Emva kokuthunyelwa komgama omde, umgangatho awuhambisani nobushushu bendawo.

Ukuthintela ukwakhiwa okungahambi kakuhle, la manyathelo alandelayo kufuneka athathwe.
1)Qala yenza umlinganiselo wobushushu bomgangatho osezantsi.Ukuba ingaphantsi kwe-10 ℃, ulwakhiwo akufunekanga luqaliswe.
2) iiyure ezili-12 phambi okanye emva kofakelo, thatha amanyathelo ayimfuneko ukugcina ubushushu bendlu bungaphezulu kwe-10 ℃
3) Ukuba ukufakwa kwi-cement, umxholo wamanzi ongaphezulu kufuneka ulinganiswe.Umthamo wamanzi kufuneka ube ngaphantsi kwe-4.5%.
4) Iqondo lokushisa liphantsi ngakumbi emnyango okanye kwifestile.Ngaphambi kofakelo, kufuneka ijonge iqondo lobushushu apho ukuba lingaphezulu kwe-10℃.Ukugcinwa kufuneka kuthathwe ukuphepha ukuhluka kobushushu.
