Ngaphandle kokukhanga kwaso okubonakalayo, isitini (njengempahla yokwakha yangaphandle) sihlala isikhathi eside.Nokho, ngokuhamba kwesikhathi, ukuwohloka kwayo akunakugwenywa.Ngenxa yokuthi izitini zinezimbotshana - zinwebeka noma zincipha ngokuya ngamazinga omswakama kanye namathonya okushisa - amanzi awusongo oluqhubekayo kanye nembangela eyinhloko yokuwohloka kwezitini emvilophini yokwakha.Kanjalo nokuvinjelwa kokunyakaza ezinhlelweni zemvilophu yokwakha izitini.
Izinhlobo Zokwakhiwa Kwezindonga
Izindonga zangaphandle zezitini zingahlukaniswa njengezindonga zokuvimbela noma izindonga zokudonsa amanzi.Izindonga zokuvimbela zakhiwe ngamatshe aqinile ngaphandle kwemigodi yokudonsa amanzi.Angakhiwa ngama-wythes angawodwa noma amaningi, ngezitini ngokuphelele, noma ngeyunithi ye-masonry kakhonkolo noma i-terra cotta back-up.Izindonga zokuvimbela izitini eziningi ze-wythe (ama-wythe amathathu noma ngaphezulu) zenzelwe ukuvimbela ukungena kwamanzi ezindaweni ezingaphakathi ngobuningi.Ngokufanelekile, inani lamanzi elimuncwa udonga ngesikhathi esithile lincane kunangala lingahlakazwa ngesikhathi esifanayo.Odongeni oluyisivikelo olwakhiwe ngezitini ezimbili zezitini (noma ezindongeni eziyinhlanganisela), ilunga lekhololo (eligaywe eliqinile ngodaka) lihlanganisa isitini sobuso nesipele se-masonry.Amanzi angena esitini sobuso alandela ilunga lekholomu phansi liye ekukhanyeni lapho liphuma khona ngejoyinti yombhede kanye/noma lapho kukhala khona izililo, noma ahlakazeke ebusweni bodonga.
Izindonga zokuthuthwa kwamanzi ziklanywe zinezimbotshana phakathi kwezindonga zangaphandle zezitini zobuso kanye nezindonga ezisekelayo (izitini, amayunithi okwakha ukhonkolo, amafreyimu ensimbi noma okhuni).Okufanelekile, amanzi angena esitini sobuso noma angena emgodini aqoqwa lapho ekhanyayo lapho ekhishwa khona ngejoyinti lombhede kanye/noma lapho ekhala.
Lapho Ingaphandle Yezitini Ihluleka
Izimpawu zokuwohloka kwezindonga zangaphandle zezitini ngokuvamile zibangelwa ukungena kwamanzi futhi zihlanganisa ukubola kanye ne-efflorescence, ukuqhekeka / ukubola / ukususwa, kanye nokuwohloka kwamalunga odaka, phakathi kwezinye izinto.
I-efflorescence yenzeka lapho amanzi egeza usawoti oncibilikayo odakeni futhi phezu kwesitini.Kubonakala ngendlela yezinhlayiya ezimhlophe ezicwebezelayo ezikhula ezindaweni zezitini njengoba amanzi ehwamuka.
Imifantu nama-spall esitini kungaba umphumela lapho amanzi amuncwa/agcinwe yiqhwa.Ukunwetshwa kwensimbi (okugxilile okugxilile noma amakhotha) kusuka ekugqwaleni ezinhlelweni zodonga lwezitini nakho kungabangela ukuqhekeka/ukugudluzwa.
Udaka, olusetshenziselwa ukuhlanganisa izitini ndawonye, ​​kufanele lube luthambile kunesitini esisibophayo (ukuze izitini zingaqhekeki ngesikhathi sokunwetshwa), futhi kufanele lusetshenziswe ngendlela (i-concave/rodded) evimbela ukuqoqwa kwamanzi endaweni ehlangene.Ukukhomba kabusha kuyadingeka lapho isibopho phakathi kwesitini nodaka kwehluleka.
Izindima Zokukhulula (Ishelufu) Ama-engeli kanye Namalunga Athambile
Isitini siyakhula futhi sivumelane nezinguquko zezinga lokushisa nokuqukethwe komswakama.Ama-engeli akhululayo (eshalofu) ayadingeka ukuze kuqinisekiswe ukuthi ukunyakaza kuhambisana phakathi kwesistimu yezitini zobuso kanye nezinhlelo zodonga ezisekela isipele, nokuthi imifantu kanye nokugudluzwa okubangelwa ukuzithiba ohlelweni kuyancishiswa.Amajoyinti athambile afakwe kuma-engeli avundlile (eshalofini), futhi nasekulawuleni okume mpo kanye namajoyinti okunweba, azokwamukela ukunyakaza futhi adale ukukhululeka ekukhulisweni kwesitini.
