Uphahla olugqunywe ngombala (iphepha le-ppgi)luhlobo olutsha lwephepha lokuphahla, elithathwa njengelona lifanelekileyo kwizakhiwo zanamhlanje, kwaye liphila ubomi obude.Kukho izilumkiso ezininzi zokufakela uphahla olugqunywe ngombala njengeplate engezantsi, kwaye kufuneka iinkosi zokwakha ezichwepheshayo zifakele.
Ngaphambi kokufakela, ukungcola kwiphepha lokuphahla elifakwe umbala kufuneka licocwe ukuze ligweme ukubola kwephepha.Ukongezelela, i-flatness yephepha kufuneka ihlawulwe ingqalelo ngexesha lofakelo, kwaye akufanele kubekho i-deformation yokugoba.Ishiti lophahla eligqunywe ngombala ligqithe omnye komnye nge-wave crest, ke ngoko yamkelwa ngabasebenzisi abaninzi.Yonke inkqubo ye-aluminium-magnesium-manganese sheeting sheet ithatha imowudi yokuthunga, enokuthi ithintele ukwenzeka kokuvuza kwamanzi, kwaye inenkqubo elungileyo yokuhambisa amanzi, ngakumbi kwimozulu yemvula enkulu, amanzi anokukhutshwa ngexesha, Inokuphepha uxinzelelo olukhulu olubangelwa kukukhutshwa kwamanzi kunye nokuthintela ukuguqulwa kweprojekthi.Oku kuya komelela ngakumbi, kwaye akuyi kubakho ukuvuza kwamanzi.Kungcono ukuba ube ne-anchoring ethembekileyo, gcina ukufakela kumcaba, kwaye ungashiyi izithuba phakathi kwamaphepha entsimbi.
Ukufakwa kweshidi lentsimbi efakwe umbala kufuna inkqubo yokukhusela umbane ephuhliswe kakuhle ukusuka phezulu ukuya phezulu.Iphepha elithathiweyo linokusetyenziswa njengesixhobo sokuphelisa umoya kuphela, kwaye akukho mfuneko yokuseta ibhanti lokukhusela umbane.Ingaphinda isetyenziswe ngokubambisana nebhanti yokhuseleko okanye intonga yombane ukwenza inkqubo yokukhusela imibane emininzi ekhuselekileyo;indlela yokufakela ukusuka kwinqanaba eliphakathi ukuya kumda, kwaye indlela yokudibanisa i-lap isuka ephantsi ukuya phezulu.Emva kokufakela umgca wokuqalisa ukufakwa kwentsimbi, khetha i-self-tapping screws ukutshixa iziphelo zombini, uze ufake ipleyiti yesibini yentsimbi.Kuyimfuneko ukufakela ishidi lokuphahla elinombala wesibini kwaye uphawule ukuba kukho ukuphambuka kwephepha, kwaye kufuneka ihlangabezane neemfuno zokuyila.Emva kokuba ukufakela kugqityiwe, nikela ingqalelo ukujonga ukuba ngaba kukho naziphi na izinto ezishiyiweyo.Ukuba ukuqiniswa akwanele, kuya kubakho ukuvuza kwemvula, ngoko qiniseka ukuba uhlawule.
