Liyini iphepha lokuphefumula? Isetshenziselwa ini? Ungayifaka kanjani?
Iphepha lokuphefumula liwuhlobo lwesakhiwo esingangeni manzi futhi esiphefumulayo, ikakhulukazi esisetshenziselwa uphahla lwamathayela, uphahla lwensimbi, izindonga zangaphandle kanye nezinye izakhiwo zokubiyela. Ukuqina kwayo okuhle kakhulu kanye nezinkomba zokusebenza zokulwa nokuguga kuholela ekuthuthukisweni kwemboni.
Umphumela wephepha lokuphefumula
Iphepha lokuphefumula lifakwe ngemuva kwebhodi lokulenga, ngakho-ke umugqa wesibili wokuzivikela wesakhiwo. Uma siyifaka ngendlela efanele, kufanele ikwazi ukwenza imisebenzi emithathu eyisisekelo.
Into yokuqala futhi ebaluleke kakhulu ukuthi iphepha lokuphefumula liyisithiyo samanzi sokusekela ngemuva kwebhodi langaphandle. Ibhodi langaphandle ngokwalo liyisithiyo sokuqala, kodwa imvula eqhutshwa umoya noma iqhwa lizobhodloza futhi lingene ngaphakathi, ngakho umgoqo wamanzi wokusekela uyadingeka.
Okwesibili, iphepha lokuphefumula lingasebenza futhi njengesendlalelo esingangenisi umoya, esingavimba umoya oshisayo nobandayo ukuthi ungangeni odongeni; Yebo, imfuneko iwukuthi zonke izithungo kufanele zivalwe ngokugcwele. Umsebenzi obalulekile wokuklama wephepha lokuphefumula ukunciphisa izindleko zokwakha ukusetshenziswa kwamandla, nokunciphisa ukungena komoya kanye nokuvuza komoya okungenzeka.
Umsebenzi wesithathu wephepha lokuphefumula umsebenzi wawo wesithathu: ukuvumela umhwamuko wamanzi ungene ngokukhululekile, ngakho umhwamuko wamanzi ngaphakathi kwesakhiwo ungahwamuka uye ngaphandle ngaphandle kokubanjwa esakhiweni futhi ubangele isikhunta nokubola. Uma iphepha lokuphefumula lingenaso lesi sici, khona-ke kufana nokubeka i-raincoat eqinile endlini: ingavimbela amanzi ngaphandle, kodwa futhi ivimbela umhwamuko wamanzi ophuma ngaphakathi; ngokuphambene nalokho, iphepha lokuphefumula limbozwe Ijazi langaphandle lenzelwe ukuthi lingangeni manzi futhi libe ne-vapor-permeable, ukuze isakhiwo singabangeli izinkinga ngenxa yomswakama wamanzi.
Yini okufanele ngiyinake lapho ngifaka iphepha lokuphefumula?
Iphuzu eliyisisekelo: ikhwalithi yokwakha ibaluleke kakhulu kunokukhethwa kwezinto ezibonakalayo. Kungakhathaliseki ukuthi yimuphi umkhiqizo wephepha lokuphefumula okhethiwe, uma ungafakwanga kahle, kuwukumosha imali. Inkinga ebangelwa ukungalifaki iphepha eliphefumulayo elifanele ingaphezu kwalokho elingakwazi ukuyixazulula. Eqinisweni, akunzima kangako ukuyifaka, kodwa kudinga ukuqonda okuyisisekelo kwesimiso sokuphefumula kwephepha. Izidingo zokufaka ezinemininingwane ngokuvamile zitholakala kuwebhusayithi yomkhiqizi kanye nomthengisi.
Enye yezindlela ezidingekayo zokufaka iphepha lokuphefumula ukucabanga ithonsi lemvula elidonsela odongeni olungaphandle lwendlu yakho. Amandla adonsela phansi ayidonsela phansi ngodonga. Uma yonke imithungo, imifantu, kanye nezimbobo kuvalwe konke, Futhi ingaphandle ifakwe ngendlela yokuthi idlulelane, khona-ke ukudonsa kwamanzi emvula ekugcineni kuzowela phansi. Kodwa uma ithola i-node ephukile noma engagcwali, izongena ephepheni lokuphefumula futhi ingene esakhiweni esikhulu.
Iphepha lokuphefumula kufanele lifakwe kusuka phansi kuya phezulu ukusuka phansi kuya phezulu. Ngesikhathi esifanayo, kuyadingeka ukuqinisekisa ukuthi yonke imithungo evundlile inamayintshi angu-6 (150mm) agqagqene okungenani, futhi yonke imithungo eqondile inama-intshi angu-12 (300mm) agqagqene. Uma ufuna ukufaka iphepha lokuphefumula ngaphambi kokumisa udonga, kufanele ubeke impahla eyanele ngaphansi kodonga ukuze umboze ipuleti lekhanda eliphansi ngaphansi kokumiswa. Kubalulekile ukuqaphela ukuthi imigqa eqondile ibaluleke kakhulu njengemigqa evundlile, ngoba imvula eqhutshwa umoya izodala ukuthi amanzi emvula ahambe eceleni, futhi akhuphukele phezulu ephepheni lokuphefumula elifakwe kahle.
