Ehlobo, ngisho nokuphumula, futhi kungasebenzi, ezweni kuyadingeka ukugeza ithuba. Indlela elula yokuyihlela emgwaqweni, hhayi endlini. Ungenza i-Portable - eshawa ephathekayo. Lokhu kuyindlela enhle kakhulu okokuqala. Kepha ngifuna okuthile okuphelele. Ukuze wenze lokhu, wakhela ehlobo lokugeza ehlobo ekhetini. Yena, yize emile, kepha ukukhanya.
Ihlobo elithandekayo
Ake siqale ngamamodeli alula kakhulu ukuthi namadivayisi wekhabethe noma iziqukathi eziphakeme azidingi. Kunemiphefumulo eselula esebenza ngomgomo wepompo yonyawo. Umthombo wamanzi noma yisiphi isitsha esethwe eceleni kwabo - ibhakede, ubheshi, ithangi - yini. Kwehliswa kuze kube sekupheleni kwe-hose exhunywe kwipompo yezinyawo, okuvame ukubukeka njenge-rug.
Umlenze ehlobo egeza - i-toptun
I-hose ngokunisela ingaxhunywa kokukhishwa kwale "pump". Ukuthola ukusakazwa kwamanzi, ngaphesheya kombhoxo ngokushintshana ngokucindezela imicamelo yamampunge. Amakhono - amanzi aya.
Yini enhle le nketho, ungayithwala nawe. Ukushisa emgwaqweni - geza otshanini. Ngabanda - waya endlini, wabeka umkhombe, wageza lapho. Futhi, le geza ingathathwa nge-hike - ibekwe kwiphakheji ejwayelekile. Okunye futhi kulawulwa ngokushisa kwamanzi: Kuthululelwe ukufudumala - geza ngokufudumala. Ufuna ukuzivuselela - bashaya ibhakede lamanzi kakhulu. Inketho enhle yomphefumlo wokusebenzisa ehlobo.
Ukugeza okumisiwe ehlobo e-Dacha
Esesicini somphefumlo omile, umbuzo wokuqala uphakama: lapho ungasusa khona amanzi. Uma sekuvele kukhona umgodi wendlu yangasese, ungavula ipayipi lapho. Kepha lesi sinqumo asisihle kakhulu uma usebenzisa ama-bacteria noma amalungiselelo wokuphinda usebenzise imfucumfucu emgodini. Kulokhu, umswakama othile uyadingeka, nangokugeza kuzobe kungaphezulu kokujwayelekile.
Okokugeza, kungcono ukwenza umgodi wokugcina ohlukile. Uma inhlabathi enekhono elijwayelekile lokudonsa amanzi, kwanele ukumba eceleni komgodi ocishe kube ngu-60 * 60 * 60 cm, lala ubumba lwalo, lungenziwa izitini zalo. Lokhu kufanele kwanele ukusetshenziswa kwamanzi okujwayelekile. Uma umndeni wakho ubhekisela ekukhipheni "kwe-waterfowl" noma amanzi amabi, yenza umgodi ngaphezulu.
Umphefumulo wamanzi wamanzi
Emhlabathini onesihlabathi, ungabhekana nenye inkinga: isihlabathi singaphenduka. Lapho-ke izindonga zingaqiniswa ngegridi, zingqongqoze ezinhlangothini zezikhonkwane. Enye inketho ukudonsa izindonga ngamabhodi (njengasesithombeni). Kepha kungukuthi uma ibhodi lisezinsalweni.
Isizinda
Noma yimuphi umphefumulo wasehlobo, unesisindo esivame ukuvela kancane. Ngakho-ke, isisekelo saso asisinambi kakhulu: akunangqondo ukungcwaba imali. Ngokuvamile sebenzisa amabhlogo amancane wesisekelo akhombisa ngokwamandla. Imiphefumulo ekhetwini ivela ukuthi iphakanyiswe ngaphezulu kwezinga lomhlabathi ngo-20 cm noma njalo. Lokhu kwanele ngokhuni oluphathwe (uma lusetshenziswa njengohlaka) aluzange lubole.
Amabhlogo wokwakha noma akhishwe kwikholomu kakhonkolo
Uma uzopheka uhlaka kusuka kwensimbi, ungakubeka nhlobo kuma-slabs ahamba noma isitofu esisethwe ezingeni. Uma ufisa, ungaphonsa amakholomu ngokwabo: Beka ifomu, beka ukuqiniswa bese uthele ukhonkolo.
Uphahla
Usayizi wesehlakalo ukhethwe ngokunqumela: Azikho izindinganiso lapha. Ngaphezu kwalokho, ikhabethe lokugeza livame ukuphela kwezingxenye. Kokunye, kufanelekile, ngokwesibonelo, igumbi le-eydijithali noma igumbi le-heater yamanzi (i-electro noma ngokhuni olusekelwe - ngaphansi kwezimo). Othile uhhafu wesibili uhlela ukuhlala ngaphansi kwekamelo lokugcina noma ukugcina okusungula. Ngakho-ke imiphefumulo yezwe ayihlali njalo i-Cabin "ukugeza".
Uma kuhlelwa ukwakhiwa okulula, lapho zizogeza khona kuphela, futhi inketho elula kunazo zonke - ngesihenqo esinqunyelwe emnyango, ungathatha amasayizi amancane acishe abe ngu-90 cm (ukudweba ngezansi), ukuphakama of the racks ngaphandle kokuthatha ithangi - 2.2 m noma ngaphezulu (uma umndeni mude).
Umdwebo wekhabethe lokugeza ekotishini (ngosayizi omncane)
Kepha ububanzi obunjalo bude nokulula: eduze kakhulu, ngisho nabantu besethi esezingeni eliphakathi. Ngokukahle ngokunethezeka ngobubanzi obuncane okungenani bangama-100 cm, futhi okungcono - 120 cm. Loluhlaka luqoqwe kusuka kumabha ensimbi noma ngokhuni.
Isihloko ngesihloko: Igumbi lokuphila elihle ngesitayela se-hi tech senzele ngokwakho
Insimbi yanama ini
Uhlaka lwensimbi lomphefumlo lubilisiwe ekhoneni ngobukhulu okungenani be-4-5 mm. Ububanzi bamashalofu bukhethiwe ngokuya ngomthwalo ohleliwe. Imephu uhlaka oluvame amathangi anamanzi nokufafaza. Uma uhlela phezulu ukubeka isitsha sesikwele sepulasitiki samalitha nge-100, bese umboza izindonga ngefilimu, indwangu enezinto ezifakiwe noma okuthile okulula, ungathatha isigaba esisezingeni eliphansi. Uma uhlela, ngokwesibonelo, imigqomo emibili engama-200, kanye nekhabethe legeza ezweni ukuthuthwa nhlangothi zombili nge-clapboard, umthwalo uzohluke ngokuphelele. Futhi lapha udinga izingxenye ezinkulu.
Uhlaka lomphefumlo wensimbi endlini
Olunye uhlaka lwensimbi lomphefumlo wasehlobo lungenziwa kusuka kushubhu elifakwe ama-profiled. Ubukhulu odongeni lwama-racks ngu-3 mm, 2 mm ulungele uhlaka. Inesigaba esingunxande noma sesikwele, esenza kube lula kakhulu ukubopha amakhreyithi nosizi. Ukunamathisela okuthile ekhoneni, kuvame ukuvela kuwo kuqala ukuklebhula imigoqo, futhi yonke imichilo ilungiselelwe kuBruus. Ku-tube enezinhlayiya, uhlaka lungalungiswa ngqo - ama-bolts noma izikulufa ezinezimbobo zangaphambi kokufuduka.
Uhlaka lwensimbi luhlelwe kahle. Uma kungekho divayisi, ungenza ifreyimu evuthayo ekuxhumeni okuvinjelwe. Yenza izingcweti futhi ukuze: Sika amapayipi wobude obufunayo, thatha amakhona abukhali abukhali bese uqoqa uhlaka kuma-bolts.
Isibonelo umhlangano kuma-bolts
Uma kwenzeka uhlela ukufunda ukupheka indlela ye-welding yensimbi yabaqalayo kuchazwe lapha, ukukhetha komshini we-welding ulapha.
Kusuka ngokhuni
Uhlaka lwamapulangwe lomphefumlo wasemgwaqweni luvunwa kusuka kubha. Ngokugculiseka okungezansi, imvamisa kungu-100 * mm noma ngo-150 * mm. Ama-rack angabeka isigaba esincane sesiphambano. Kuya ngomthwalo. Uma ithangi livumayo ophahleni, yenza ama-racks avela e-weave. Uma ugcina ophahleni kuphela (amanzi afudumele eTitan eduze) noma ithangi elincane kakhulu, bese kuthi no-50 * 50 wanele.
Izindlela zokuxhuma izingodo zokuhlelwa kwesehlakalo: Spike / ama-grooves namakhona
Ama-Brucks angafakwa ngokuhlukile. Uma ngokunembile - udinga ukuphuza ameva nama-grooves. Uma ngokushesha, ungadonsela ngqo, uqinise ukuxhumeka kumakhona.
Ubeke ama-racks, ngokushesha enze ukudonsa okuphezulu. Sekuvele impela 50 * 50 mm noma 50 * 40 mm. Yenza enye imicu ephakathi. Kungaba khona okukodwa, okubili, ngisho amathathu. Uma imiphefumulo iya eshawini, ukulingiswa kwezithambisi, kungcono ukulungisa kaningi: kuzokwazi ukuguqula kalula amapulangwe abushelelezi. Izinga lezinto zokwakha ezivela emakethe, ukulibeka ngobumnene, liphansi. Kufanele ulungise ama-shoals ejometry ngezindleko zamandla.
Ukwakhiwa kohlaka oluvela kubha elikhonjiswe kuvidiyo
Ukushefa
Sika uhlaka nganoma iyiphi impahla:
- Cleanna noma ifilimu. Okufushane, kepha kuyashesha futhi kushibhile. Kwanele isizini. Ngisho nesibhengezo esidala singasetshenziswa (banikezwa cishe umsebenzi kuma-ejensi wokukhangisa).
- Izindwangu ezinombhalo. Inketho ilula kakhulu futhi ayibizi. Ungasebenzisa impahla ethatha ama-awnings, amatende.
Isembozo sesabelomali sesabelomali - Indwangu nefilimu
- Amapulangwe. I-lining, ukulingiswa kwezingodo, i-block House, njll. Umzuzu owodwa: ungathengi i-crude lining noma i-block House, uma udinga ukuyilungisa khona lapho. Ngonyaka uyofa kakhulu, ngenxa yalokho okuzovela ama-ges. Kwesinye isikhathi ama-dengelion abaluleke kakhulu ukuthi iphunga ligxumela ngaphandle kwama-grooves. Sinomoya omncane wemvelo. Noma kunjalo, uma wenza umgomo we-Fensi-braid (njengasesithombeni), ungasebenzisa ibhodi elijwayelekile.
Izindonga zalo mphefumulo wehlobo zenziwa ngokuya ngomgomo we-fensing-braid
- Slate. Ingabeka i-asbestos ne-polymer. Yize wonke umuntu azi ukuthi i-asbest iyingozi, basakwazi ukunquma kuyo.
- Profist. Uma kukhona ukunquma ngemuva kokwenza uthango kusuka endaweni efanelekile, ungazivumelanisa nezimo.
Imiphefumulo ekotishi elivela kuchwepheshe
- Polycarbonate. Uma kungadidanisi i-transclency yalokhu okuqukethwe, ingasetshenziswa. Ukusikeka kuphela okuzodinga ukushumeka, ngaphandle kwalokho uthuli / umswakama uwela kumaseli, i-algae izohlala. I-Polycarbonate, vele, izoyeka ukuba sobala, kepha izothola umthunzi ompunga wokuthi awukwazi ukuyithanda.
Ungakwazi nanoma yiluphi olunye uthango ozofika engqondweni futhi uzokwenza imisebenzi yakho. Isibonelo, esigabeni esisodwa se-cottage, umkhono wawumbozwe eshawini. Ngohlobo lwehlombe.
Ungashintsha uvike
Ithangi lomphefumlo
Njengethangi lomphefumlo wasehlobo sebenzisa noma yisiphi isitsha esifanelekomnotho. Imvamisa kakhulu - le yi-barrel - insimbi noma ipulasitiki. Uma kungekho lutho olufanele, ungathenga isitsha. Kunezinhlobonhlobo ezinkulu: ipulasitiki, insimbi - kusuka ku-ferrous Metal nensimbi engenasici.Ipulasitiki akuwona wonke umuntu othanda, njengoba amanzi embi kakhulu kubo. Ezifundeni eziseningizimu, kungazinzile - ukushisa nokunye kwanele, kepha ngomucu ophakathi, kungalimaza. Yize kulesi sifunda, iningi lehlobo, amanzi ngisho nasemigqonyeni yensimbi emnyama kudinga ukufudumala. Ngakolunye uhlangothi, iziqukathi zepulasitiki azibizi, zilula, kukhona bobunjwa obuluhlaza obusezingeni, okusho ukuthi - ziba kahle ngohlaka lomphefumlo futhi asikho isidingo sokwakha indlela yokuqinisa.
Emgqonyeni wensimbi, amanzi azofudumeza ngokushesha, ikakhulukazi uma upenda ube mnyama. Kepha uma kuvela ensimbi ejwayelekile, ngasekupheleni kwesizini kuzoba nokugqwala okuningi. Kakhulu lokho kuzobonakala emzimbeni. Lona ukubuyela okuphambili kwamathangi anjalo. Kungcono kakhulu - kusuka ngensimbi engenasici. Uma imali ivunyelwe, zivumele lokho.
Ihlobo lomphefumlo wehlobo
Kunokuhlukahluka okubili kwedivaysi yomphefumlo wezwe: lapho i-septic (umgodi we-porain) itholakala ngaphansi kwegeza. Ngemuva kwalokho ungavele wenze ubulili obunamandla: amabhodi amukelekile ngegebe le-3-5 mm. Inketho elula esebenza kahle emhlabathini onesihlabathi futhi ecwebezelwe. Kulokhu, amanzi ahamba ngokushesha okukhulu, ngaphandle kokubangela noma kuphi, ngoba idivaysi enjalo ayilethi noma yikuphi ukuphazamiseka.
Kepha le ndlela ilungele kuphela uma uhlela ukusebenzisa i-SHACH kuphela ngesimo sezulu esifudumele. Futhi intwasahlobo-ekwindla e izohamba - izobanda, ngoba izovutha ngezansi.
Uma kudingeka i-drain ejwayelekile noma udinga ukuhola ama-drains ohlangothini (umsele wokukhipha umsele kude nokwakhiwa), udinga ukwenza i-pallet emphefumulweni. Icala elilula ukuthenga okulungele. Ngemuva kwalokho, ngesikhathi sokwakha nokukhetha usayizi wohlaka, kuzofanele ubheke usayizi wepallet: imigoqo iyadingeka lapho inamathiselwe khona. Xhuma, futhi, Okujwayelekile: Beka i-Siphon nge-hose eguquguqukayo, njengasendlini yokugezela.
Lapho ufaka i-pallet, lapho kukhipha idivaysi engezansi, imigoqo ikubeka ukuze iqhubeke kahle
Uma i-pallet ipulasitiki, imigoqo nje ezungeze i-perimeter ngeke yanele: kudinga ukusekelwa kwako, uma kungenjalo "uhamba". Lesi sisekelo sivame ukubekwa ezitini. Ungababopha ngesisombululo. Vele ungakhohlwa ukushiya indawo ye-hose yokukhipha.
Kwezinye izimo, zama ukwenza i-drain eqinile eqinile: ngaphandle kokusebenzisa i-pallet eqediwe. Kulokhu, kuthululwa ukhonkolo. Kulokhu, ukululama kosayizi odingekayo ukumba, ukujula okungaba ngu-30-40 cm. Phansi kongqimba lwamatshe anobukhulu obungu-15-20 cm ukukhishwa kanye negridi yokudonsa. Beka amafomu. Kungahle kungasuswa - kusuka ezitini. I-Tram yamatshe echotshoziwe, yathela lonke ukhonkolo (uMark M 250). Isonto (emazingeni okushisa angu-17 ° C nangaphezulu) alinde kuze kube yilapho isisekelo sizothayipha amandla. Ngemuva kokuqhubeka nokuqhubeka: Beka uhlaka bese uqhubeka nokwakhiwa.
Isibonelo se-pallet ekhonkolo
Ukugcwalisa ithangi nokushisa kwamanzi
Ngokugcwaliswa kwethangi lokugeza lamanzi, imvamisa akunankinga. Kwesinye isikhathi amabhakede adonswa amanzi - ufuna ukugeza, uzogqoka. Akuyona elula impela, kodwa, kepha kwenzeka ... uma kukhona ukuhlinzekwa kwamanzi ezweni, gcwalisa nge-hose, ipayipi lokuphakelayo eline-valve lifakwe. Kuyadingeka ukwengeza amanzi - bavula i-crane, ithangi lagcwaliswa - livaliwe.Kanjani ukwenza ithangi eligcwele ngokuzenzakalela
Okuthuthuke kakhulu kwenza ukugcwaliswa okuzenzakalelayo. Lapho-ke ukutholakala kwamanzi kuvula / kuvala uhlelo lokuntanta ngohlobo olumi ethangini. Uma kwenzeka kwenzeka ukuqhekeka kufanele kuhlinzekwe nge-drain yamanzi amaningi. Futhi, kuyinto efiselekayo, kushiye ikotishi, ligcwele i-feed crane. Futhi-ke ungaguqula omakhelwane bakho esigangeni.
Idivaysi yamathangi amanzi ngokulawula okuzenzakalelayo kwezinga
Isikimu sokuqashwa kwesihlungi esiyisibonelo sethulwa kwisibalo phezulu. Uyacelwa uqaphele: Uthango lwamanzi eshawini kwenzeka eduze kwendawo: Kuvame ukuba namanzi afudumele kakhulu. Lo mbhobho kuphela ofakwa emaphethelweni aphambene wokungena kwamanzi abandayo, ngaphandle kwalokho amanzi asazobanda.
Amapayipi amabili asendaweni yokuhambisa indle: okuchichimayo (imibala yesinaphi). Ngosizo lwayo, ithangi ngeke lichichime emcimbini wokuqhekeka kwendlela yokuntanta. Ukudonsa okwesibili kokuthuthwa kwendle kwe-drain ephelele (brown). Kuyasiza ekulondolozeni uhlelo - Plum ebusika ngoba i-crane ifakiwe kukho.
Inhlangano yokushisa
Inketho elula ukusebenzisa amandla elanga. Yebo, kufudumeza amanzi ezindongeni zethangi. Kepha i-stratum yamanzi inkulu kakhulu kangangokuba yafudumala ngokushesha. Ngakho-ke, abantu beza nokufakwa okuhlukahlukene kokushisa kwamanzi elanga.
Indlela yokushisa kwamanzi ilanga
Njengoba kushiwo ngenhla, ethangini amanzi afudumele kakhulu aphezulu. Futhi okuphakelayo kwendabuko kuya ngezansi. Okungukuthi, sithatha amanzi abandayo kakhulu. Ukuze amanzi afudumele kakhulu afike emthini, i-hose inamathele kuyo, futhi inamathele engxenyeni yegwebu, eliyeke ukubhukuda. Ngakho uthango lwamanzi lwenziwe ngenhla.
Ukusheshisa ukufudumala kwamanzi, yenza inyoka (esithombeni phezulu kwalo mdwebo ofanele). Ngaphansi kwethangi lamanzi nangaphezulu, ama-nozzles amabili awela kwesinye sezindonga zawo. Baxhumeke kwi-hose emnyama yerabha, okuyizindandatho ezisongelwa elangeni. Uma i-hose ingeyona umoya, ukunyakaza kwamanzi kuzokhuthala impela.
Uma ilanga selinganele kuwe, kepha kungenzeka ukuthwala ugesi emphefumulweni, ungasebenzisa i-TENI (emanzi). Badinga i-thermostat ukuze ukwazi ukusetha izinga lokushisa elidingekayo. Imvamisa esetshenziswa kuma-heather amanzi aqolayo, ukuze uthole.
Umdwebo wedivaysi yokushisa kwamanzi ehlobo umphefumulo
Lapho udonsa amandla okunikezwa umphefumulo, ungakhohlwa ukubeka umshini nge-RCD. Lokhu kuncane okuzoqinisekisa ukuphepha kwakho.
Ukwakhiwa kwesiteshi ekotishi: Umbiko Wezithombe
Njengomunye wezindonga zomphefumlo, kwathathwa isinqumo sokusebenzisa uthango ekugcineni kwendawo. Ukugeza kunqunywe ukuthi kwenziwe ngegumbi le-Locker - kulula kakhulu.
Inhlabathi inesihlabathi, amanzi ahamba ngokushesha okukhulu, ngoba eyokuchitha, kwangcwatshwa ngebhasi elilodwa kuphela. Ukuhlolwa kokugeza kuboniswe lokho futhi kungadingeki. Amanzi athululela okungaphezu kwami emgqonyeni, futhi akukho puddow eyabonwa.
Kwi-drain engcwatshwe ngebhasi elilodwa
Kulesi sigxobo esivele sikhona (kusuka kocingo), kwangezwa amanye amathathu. Usebenzise ishubhu eliyindilinga (kudala kudala ku-barn). Ngaphansi kwezigxobo zafela imigodi ngokujula kuka-70-80 cm. Zifakiwe kuzo, zimbozwe ngemfucumfucu. Itshe elichotshoziwe lalithululwa futhi lathela ukhonkolo.
Izinsika ezintathu ezihlangene
Emva kokufakelwa uhlaka. Wasebenzisa ipayipi elingunxande 60 * 30 mm. Kulomklamo, kukhulu kakhulu, kepha kusetshenziswe okwakukhona: izinsalela ezakhiwe kocingo.
Lapho i-welding ivumelanisa izinga
Ukushanela uhlaka lwaphansi, bese kubhekiswa ezingeni lakhe, kwakhiwa isitoko. Babike ukuphakama okulahlekile kwezitini (ukulwa, izinsalela). Konke kuthululwe ukhonkolo, kwakha ukugeleza ebhasini.
Ukwakheka kwe-stok.
Iqondaniswe phansi futhi engxenyeni yesibili, kwesokunxele ukuba ithungwe. Saqala ukucubungula izinkuni. Ngithengwe ebhodi. Yaphathwa okokuqala ngesiketi esinamathiselwe ku-grinder. Ngemuva kokushisa ukwakheka okuvikelayo.
Ibhodi yokugaya
Ukufakwa
Ngenkathi i-Implegnation yomile, qhubeka upheka uhlaka lwensimbi eshawa. Kwafakwa i-welded ukudonsa okuphakathi kumapayipi afanayo wephrofayili. Ngemuva kwalokho isetshenziswa njengamakhono okusebenza ekuphakameni. Kumapayipi okopela avele abuza amabhodi. Kusuka kule ntambo ephezulu yokuphekeleka ephekiwe.
I-medium strap esetshenziselwa ukupheka ephezulu
Uhlaka lucishe lukulungele. Kusalokhu kubilibisa phezulu kohlaka ngaphansi komgqomo.
Uhlaka lomphefumlo olungiselelwe
Ngaphezulu kwendawo yokugeza yengeze ukuqiniswa kwe-Upper Strip phakathi. Kukhona namakhona amabili. Ubukhulu bensimbi buba ngu-6 mm, ububanzi beshalofu bungama-8 cm. Ibanga phakathi kwalo lingaphansi kwesilinganiso: ukuze umgqomo ususelwa eceleni.
Insimbi yasetshenziswa yakudala, ngakho imbozwe ukugqwala. Uthe ku-grinder ngokuhamba kwesikhathi isigcawu sesehlakalo uhlaka kathathu odwetshwe ngopende. Ikhethwe luhlaza okwesibhakabhaka, njengoba kwahlelwa ukubona ishawa nge-Blue Polycarbonate.
Upende ohlaza okwesibhakabhaka ngokugqwala
IPolycarbonate yafakwa esikhungweni sokuzishaya. Lapho ufaka, awekho amawashi akhethekile asetshenziswa, noma ajwayelekile. Lokhu ukwephulwa kobuchwepheshe obungaholela eqinisweni lokuthi ku-ITHyHent Weather iro. Lokhu okuqukethwe kunezinga lokushisa elikhulu elithuthukiswa, ngoba kulokhu kulungiswe ohlakalweni lwensimbi.
Ungayilungisa kanjani i-polycarbonarbonate, funda lapha.
I-polycarbonate efakiwe
Umgqomo uyagezwa emgqonyeni. Ifakwe kumapayipi. Eyokuqala - echibini lamanzi, okwesibili - ngokuxhuma amanzi angena. Emva kwalokho, umgqomo wapendwa emnyama.
Umgqomo wokufudumeza kwamanzi okusheshayo upende omnyama
Isihloko ngesihloko: Ukukhiqizwa kwamalambu we-LED kwenze ngokwakho
