Njengoko sisazi ukubaindawo yokupholisa umoya kwimizi-mvelisozifakwe ecaleni kodonga okanye phezu kophahla. Makhe sazise iindlela ezimbini zofakelo.

1. Indlela yokufakela isipholileyo somoya esisingqongileyo ecaleni kodonga:

I-40 * 40 * i-4 yentsimbi ye-angle yentsimbi isetyenziselwa ukudibanisa nodonga okanye ipaneli yefestile, i-air duct kunye ne-angle yentsimbi yentsimbi ixutywe nge-rubber ukukhusela ukunyakaza, kwaye zonke izikhewu zitywinwe ngeglasi okanye i-sement mortar. I-elbow yokubonelela ngomoya iya kulungiswa ngokweemfuno zemizobo, kwaye indawo enqamlezileyo ayiyi kuba ngaphantsi kwe-0.45 yeemitha square. Xa ufaka i-air duct, faka i-hanger kwi-bracket yokufakela ukuze bonke ubunzima bombhobho womoya buphakanyiswe kwi-bracket. Iimfuno zobugcisa: 1. I-welding kunye nokufakwa kwe-bracket ye-triangular kufuneka iqine; 2. Iqonga lolondolozo kufuneka libe nako ukuxhasa ubunzima beyunithi kunye nomntu wokulondoloza; 3. Isixhobo sokupholisa umoya esiphambili kufuneka sifakwe ngokuthe tye; 4. Icandelo leflange ephambili yenjini kunye nengqiniba yokuhambisa umoya kufuneka igungxulwe; 5. Yonke imibhobho yomoya yangaphandle eludongeni kufuneka ingangenwa manzi; 6. Ibhokisi ye-junction yeyunithi ephambili kufuneka ifakwe ngokuchasene netempile ukuze igcinwe lula; 7. Ingqiniba yombhobho womoya kufuneka ivalwe amanzi etempileni ukunqanda ukuphuma kwamanzi egumbini.

2. Indlela yokufakela uphahla lweworkshop yesakhiwo sodonga lwezitena:

1. Sebenzisa i-40 * 40 * 4 isakhelo sentsimbi ye-angle ukuze udibanise kwaye ulungise ngeebholiti zekhonkrithi eziqinisiweyo; 2. I-truss yephahla kufuneka ibe namandla okwaneleyo ukuthwala ubunzima beyunithi kunye nabasebenzi bokulondoloza; 3. Ubungakanani bokuvula uphahla akufanele kube bukhulu kunobukhulu bokufakelwa kombhobho womoya 20mm; 4. Ufakelo kufuneka lube tye; 5. Icandelo leflange ephambili yenjini kunye nengqiniba yokuhambisa umoya kufuneka igungxulwe; 6. Yonke imibhobho yomoya eluphahleni kufuneka ingangeni manzi; 7. Iikona ezine mazibonelelwe ngeefreyimu zokuxhasa.
