Yintoni iphepha lokuphefumla? Isetyenziselwa ntoni? Ukuyifaka njani?
Iphepha lokuphefumula luhlobo lwesakhiwo esingenamanzi kunye nezinto eziphefumulayo, ezisetyenziselwa kakhulu uphahla lweetayile, uphahla lwentsimbi, iindonga zangaphandle kunye nezinye izakhiwo ezivaliweyo. Ukomelela kwayo okugqwesileyo kunye nezalathisi zokusebenza ezichasene nokuguga zikhokelela kuphuhliso lweshishini.
Impembelelo yephepha lokuphefumla
Iphepha lokuphefumula lifakwe emva kwebhodi yokuxhoma, ngoko ke ngumgca wesibini wokukhusela isakhiwo. Ukuba siyifaka ngokuchanekileyo, kufuneka ikwazi ukwenza imisebenzi emithathu esisiseko.
Into yokuqala kunye neyona nto ibalulekileyo kukuba iphepha lokuphefumula liyi-backup barrier yamanzi emva kwebhodi yangaphandle. Ibhodi yangaphandle ngokwayo ngumqobo wokuqala, kodwa imvula eqhutywa ngumoya okanye ikhephu iya kutyhoboza kwaye ingene ngaphakathi, ngoko ke umqobo wamanzi uyimfuneko.
Okwesibini, iphepha lokuphefumla linokusebenza njengomaleko ongangeni moya, onokuvala umoya oshushu nobandayo ukuba ungangeni eludongeni; kunjalo, into efunekayo kukuba zonke iiseams kufuneka zitywinwe ngokupheleleyo. Umsebenzi obalulekileyo woyilo lwephepha lokuphefumula kukunciphisa iindleko zokwakha ukusetyenziswa kwamandla, kunye nokunciphisa ukungena komoya kunye nokuvuza komoya okunokwenzeka.
Umsebenzi wesithathu wephepha lokuphefumla ngumsebenzi walo wesithathu: ukuvumela umphunga wamanzi ukuba ungene ngokukhululekileyo, ngoko ke umphunga wamanzi ngaphakathi kwesakhiwo unokunyuka uphume ngaphandle ngaphandle kokubanjwa kwisakhiwo kwaye ubangele isikhunta kunye nokubola. Ukuba iphepha lokuphefumula alinayo le mpawu, ngoko kufana nokubeka i-raincoat engqingqwa endlwini: inokuthintela amanzi ngaphandle, kodwa iphinde ivimbele umphunga wamanzi ophuma ngaphakathi; ngokuchaseneyo, iphepha lokuphefumula lihlanganiswe Ijacket yangaphandle yenzelwe ukuba ingabi namanzi kunye ne-vapor-permeable, ukwenzela ukuba isakhiwo asiyi kubangela iingxaki ngenxa yomphunga wamanzi.
Yintoni endimele ndiyibeke ingqalelo xa ndifaka iphepha lokuphefumla?
Isiseko esisisiseko: umgangatho wokwakha ubaluleke ngaphezu kokukhethwa kwezinto eziphathekayo. Kungakhathaliseki ukuba yiyiphi imveliso yephepha lokuphefumula elikhethiweyo, ukuba alifakwanga ngokufanelekileyo, liyinkcitho yemali. Ingxaki ebangelwa kukungafaki iphepha elichanekileyo lokuphefumla ngokuqinisekileyo ingaphezulu kunokuba inokusombulula. Enyanisweni, akunzima kangako ukuyifaka, kodwa kufuna ukuqonda okusisiseko komgaqo wephepha lokuphefumla. Iimfuno zofakelo ezineenkcukacha zidla ngokufumaneka kwiwebhusayithi yomenzi kunye nomthengisi.
Enye yeendlela ezifunekayo zokufakela iphepha lokuphefumla kukucinga ithontsi lemvula ena kudonga olungaphandle lwekhaya lakho. Umxhuzulane uwutsalela ezantsi ngodonga. Ukuba yonke i-seams, iintanda, kunye nokubhoboza konke kutywinwe, Kwaye ingaphandle ifakwe ngokulandelelana kokugqithwa, ngoko ke ukuhla kwamanzi emvula kuya kuthi ekugqibeleni kuwele emhlabeni. Kodwa emva kokuba ifumene i-node eqhekekileyo okanye engapheliyo, iya kungena kwiphepha lokuphefumula kwaye ingene kwisakhiwo esiphambili.
Iphepha lokuphefumla kufuneka lifakwe ukusuka ezantsi ukuya phezulu ukusuka ezantsi ukuya phezulu. Kwangaxeshanye, kuyafuneka ukuqinisekisa ukuba yonke imithungo ethe tyaba inee-intshi ezi-6 ubuncinane (150mm) ezidityanisiweyo, kwaye zonke iithungo ezithe nkqo zine-intshi ezili-12 (300mm) ezidityanayo. Ukuba ufuna ukufaka iphepha lokuphefumula ngaphambi kokumisa udonga, kufuneka ugcine izinto ezaneleyo phantsi kodonga ukuze ugubungele ipleyiti yentloko phantsi kwe-erection. Kubalulekile ukuba silumke ukuba imijikelo emi nkqo ibaluleke njengemijikelo ethe tyaba, kuba imvula eqhutywa ngumoya iya kubangela ukuba amanzi emvula ahambe ecaleni, kwaye anyuke aye phezulu kwiphepha lokuphefumla elifakwe ngokufanelekileyo.
