I-Crawlspace Egcwele Izikhukhula, Amanzi Amile Ngaphansi Kwendlu, kanye Nokukhishwa Kwengozi Kagesi¶

Ukuthola amanzi amile ehlanganiswe enhlabathini noma umgoqo womhwamuko wepulasitiki wendawo yokuhlala kungenye yezimo eziphuthumayo ezifihlekile zesakhiwo esiyingozi kakhulu ekhaya. Ngokungafani nesitezi esingaphansi esinobude obugcwele (indawo engaphansi egcwele izikhukhula) lapho ungakwazi khona ukuhamba uqondile phezu kukakhonkolo futhi ubone izintambo zikagesi ezicwilisiwe kusukela phezulu ezitebhisini, indawo yokukhasa iyindawo emnyama, engamasentimitha angu-45 kuya ku-90 ukuphakama (18-to-36-intshi-ukuphakama) lapho isifuba sakho, izandla, namadolo kucindezelwa khona ngokuqondile odakeni olumanzi noma amashidi epulasitiki e-polyethylene agcwele amanzi. Ngesikhathi esifanayo, izintambo zikagesi ze-Romex ezingu-120-volt kanye no-240-volt, amabhokisi okuhlangana kwensimbi avulekile, amaphampu e-HVAC e-condensate, izintambo zamandla epompo ye-sump, kanye namapayipi okushisa ensimbi alenga amasentimitha ambalwa nje ngaphezu kwamanzi noma alale ecwile ngokuphelele ngemva kokuwa ama-joists aphansi abolile. Njalo ngonyaka, abanikazi bezindlu kanye nochwepheshe bezinsizakalo bahlushwa ugesi obulalayo (ukushaqeka kukagesi) lapho zikhasa endaweni yokungena endaweni yokukhasa emanzi enikezwe amandla yibhokisi lokuhlangana elingaphansi kwamanzi noma ucingo olufakwe isiteketiso.

Ngaphandle kwe-electrocution kanye nendawo evalekile yokuminza noma izingozi zegesi yendle (ukusekela indle), amanzi amile avaleleke ngaphansi kwendlu agcwala ngokushesha ukugqunywa kwensimbi ye-fiberglass kuze kube yilapho izingubo zokulala ze-fiberglass ezigcwele amanzi ezingamakhilogremu angu-20 ziklebhuka futhi ziphahlazeke odakeni, kuyilapho umphumela westaki okhuphukayo wendlu udonsa umoya onomswakamo ongamaphesenti angu-90, Stachybotrys kanye ne-Asperresgillusisikhunta ngemva kokulimala kwamanzi), nokubola kwesikhunta okucekela phansi izinkuni kuqonde egumbini lakho lokuphumula nasemagunjini okulala. Uma noma ubani ongaphakathi kwe-crawlspace engaphenduli noma eshaywa wugesi, ungamthinti noma ungene endaweni yokukhasa; vala i-breaker kagesi yendlu enkulu futhi ushayele indawo yangakini izinombolo eziphuthumayo (911 e-United States naseCanada, 112 ngaphesheya kwe-European Union, 999 e-United Kingdom) ngokushesha. Lo mhlahlandlela uhlinzeka ngezinqubo eziphuthumayo zesinyathelo nesinyathelo ukuze unciphise amandla ezingozi zikagesi ngaphambi kokuhlola indawo ekhukhumele, ukuhlonza ukuthi amanzi aphuma epayipini eliqhumayo elicindezelwayo, indawo yokukhipha indle eluhlaza, noma ukungena kwamanzi angaphansi komhlaba, ukupompa amanzi amile ngaphandle kokucekela phansi isisekelo sakho, futhi womise i-subfloor ngaphambi kokuba i-fungal wood rot ixegise i-floor yakho.

Yenza lokhu manje¶

Uma ubuka i-crawlspace yakho yangaphandle noma yangaphakathi bese ubona amanzi amile, amashidi epulasitiki antantayo, noma ukufakwa kwamanzi okugcwele amanzi kulenga kuma-joists aphansi, yenza lezi zenzo eziyisithupha ngokushesha:

1. UNGAKHASELI ENDAWENI YOKUKHASELA OKUMUMAZI KUZE KUBE INDLU EYINHLOKO KAgesi IYAVALWA: Ungalinge uthembe i-circuit breaker yegatsha noma ucabange ukuthi zonke izintambo zinamathiselwe phezulu kuma-joists aphansi okhuni. Ukufakwa kwe-fiberglass ewile kuvame ukudonsa amabhokisi okuhlanganisa angu-120V, iziguquli zensimbi yokuncencethwa emnyango, amaphampu e-HVAC e-condensate, nezintambo zamandla okukhipha umswakama ziqonde phansi echibini. Hamba uye kuphaneli yakho yensizakalo kagesi eyinhloko (emhlabathini owomile) bese upheqa i-Main 100A/200A Breaker ukuthi IVALI* ngaphambi kokuthi ukhanyise ngisho nethoshi ngaphakathi kwe-hatch izandla zakho zisesinqeni.
2. Nquma emizuzwaneni engu-60 ukuthi amanzi e-crawlspace aphuma yini epayipini lamanzi lasendlini elicindezelweyo, umzila wokukhipha indle, noma ngaphandle kwemvula/amanzi angaphansi komhlaba:
3. Hlola Imitha yakho Yamanzi kuqala: Njengoba bonke ompompi basendlini bevaliwe, bheka unxantathu omncane ogeleza kancane obomvu/osiliva (ukudayela okukhomba ukuvuza) kumitha yakho yamanzi. Uma ukudayela kujikeleza, ipayipi elinengcindezi elibandayo noma elishisayo liqhume ngaphakathi kwendawo yokukhasa (ipayipi eliqhuma); vala i-Main House Water Shutoff Valve* ngokushesha.
4. Hogela futhi ubheke amanzi ngaphandle kwendawo yokuchanyuselwa: Uma uzwa iphunga elibi legesi yendle ye-hydrogen sulfide noma ubona iphepha lasendlini yangasese nodaka olunsundu luntanta eduze kwesitaki esikhulu se-iron noma i-PVC drain, ipayipi elikhulu lokudonsa indle lihlukene ngaphansi kwendlu; yeka ukugeza zonke izindlu zangasese nokusebenzisa noma yimaphi osinki noma amashawa.
5. Ungalokothi ungene endaweni yokukhasa egcwele izikhukhula uwedwa noma ngaphandle kwebhodi lokukhasa ngokhuni, amabhuzu erabha, nesibani esisebenza ngebhethri: Ukufakwa endaweni evalekile odakeni olujulile lwe-crawlspace noma amashidi e-polyethylene aphithene kuyingozi enkulu empilweni. Hlala njalo misa umuntu omdala wesibili ngaphandle kwe-crawlspace hatch evulekile ngefoni ngenkathi uhlola uvela embundwini.
6. Uma izikhukhula zivela epayipini eliqhume noma imvula ezumayo phezu kwesivimbeli somoya wepulasitiki, pompa amanzi aphume ngaphandle kwehashi usebenzisa iphampu esetshenziswayo engaphansi kwamanzi eyehliselwe ebhakedeni elinezimbobo elingamalitha angu-5: Awudingi ukukhasela emanzini ukuze uwakhiphe. Bomba izimbobo ezingamamilimitha angu-10 (⅜-intshi) ezinhlangothini zebhakede lepulasitiki elingamalitha angu-20 (amalitha amahlanu), beka isitini phansi ukuze sicwilise ngaphandle kokumunca udaka noma ucwecwe lwepulasitiki ku-impeller, setha iphampu elisetshenziswa ngaphansi kwamanzi ngaphakathi kwebhakede, phushela ibhakede echibini elijule kakhulu usebenzisa isibambo sepulaki esikhumbeni esomile nesibambo sokufinyelela. I-GFCI-Protected (RCD) outlet outlet.
7. Uma igceke elizungezile lisengaphansi kwamanzi ngemva kwesikhukhula sesifunda, UNGAMPOMPI indawo yokukhamba ejulile engaphansi kwebanga eliphansi yome ngokuphelele ngesikhathi esisodwa: Njengendlu engaphansi egcwele izikhukhula, uma inhlabathi engaphandle kwezindonga zesisekelo sakho igcwele izinga eliphansi kuyilapho ukungcola kwakho kwe-crawlspace kuhlala amasentimitha angu-60 kuya kwangu-90 (amafidi angu-2 ukuya kwangu-3) ukujula kunotshani obungaphandle, ukugeleza kwamanzi kubangele ukugeleza kwamanzi angaphandle ngokushesha okukhulu. phuma ngaphansi kwezinyawo zakho zepherimitha kakhonkolo (**amapayipi omhlaba / ukucekela phansi **). Linda kuze kube yilapho amanzi egceke langaphandle ebohla, bese umpompa phansi kungabi ngaphezu kwamasentimitha angu-30 (amayintshi angu-12) njalo emahoreni angu-12.
8. Donsela phansi bese ufaka isikhwama yonke into efakwa emanzini ye-fiberglass batt ethinte amanzi amile: Ukufakwa kwe-fiberglass okumanzi okulenga phakathi kwezixhumi zaphansi ngeke kome endaweni; esikhundleni salokho, ibamba amanzi awuketshezi ngokuqinile ngokumelene ne-subfloor yokhuni kanye nama-joists aphansi amasonto, izalanisa isikhunta esibola ngokushesha sokhuni (Serpula lacrymans kanye Ne-Poria incrassata) kanye nesikhunta esimnyama phakathi namahora angu-72.

Isihlahla sesinqumo: ukuhlonza umthombo we-crawlspace ogcwele amanzi kanye nokukhipha okuphephile¶

Sebenzisa lesi sihlahla sesinqumo sokusebenza ukuze ukhombe lapho amanzi e-crawlspace avela khona, ususe izingozi zikagesi nezebhayoloji, futhi wenze ukulandelana okufanele kokupompa nokomisa.

1. Yakha "Isikrini Se-Bucket Sump" Esithuthukisiwe ngemizuzu emi-3¶

1. Thatha ibhakede lepulasitiki elijwayelekile elithi 20-litre (5-gallon) bese ubhoboza izimbobo ezingamashumi amabili kuya kwamashumi amathathu 6-to-10-millimeter (¼-to-⅜-intshi) ezinhlangothini ezimaphakathi nezingaphezulu zebhakede (shiya phansi amasentimitha angu-5 / amayintshi angu-2 phansi ebhakedeni eliqinile alikwazi ukushwibilika).
2. Uma unesikrini sefasitela noma indwangu yehadiwe, yisonge ngaphandle kwebhakede nge-tape yokudonsa ukuze ugcine izintambo zokufakwa kwe-fiberglass ezintantayo ziphume emigodini.
3. Beka isitini sikakhonkolo esiyisicaba noma itshe levula ngaphakathi ngaphansi kwebhakede ukuze ulehlise isisindo, bese usetha iphampu yakho esetshenziswayo engaphansi kwamanzi (noma i-sump pump) phezu kwesitini ngaphakathi kwebhakede.
4. Namathisela 32-millimeter (1-¼-intshi) ipayipi lokulahla likathayela (elimpompa ngokushesha izikhathi ezi-3 kunepayipi elincane lasengadini) noma umsebenzi osindayo 19-millimeter (¾-intshi) wepayipi lasengadini endaweni yepompo, futhi ugijimise indawo yokukhipha okungenani amamitha angu-6 ukusuka endlini ukuya phansi ukusuka ku-10 kuya ku-10 imitha ukusuka endaweni eyimitha engu-3 ukuya ku-5 i-slope ukuze amanzi angamane abuyele emuva odongeni lwesisekelo ngeluphu eqhubekayo.
5. Phusha ibhakede echibini elijulile elingaphakathi kwendawo yokukhasela usebenzisa isigxobo eside esisuka lapho kuchanyuselwa khona, bese uxhuma iphampu ku-indawo evikelekile ye-GFCI NGAPHANDLE kwendawo yokukhasa.

2. Uwakha Kanjani Amanzi Avaleleke PHEZULU vs. NGAPHANSI Kwe-Plastic Vapor Barrier¶

• Uma amanzi ehlanganiswe PHEZU KWE-polyethylene plastic sheet: Iphepha lepulasitiki lizontanta liye phezulu libe yimigoqo futhi livale amachibi amanzi ahlukene phakathi kwemibimbi. Setha ibhakede lakho lepompo elinezimbobo ezinesisindo ngqo phezu kweshidi lepulasitiki ekucindezelekeni okuphansi kakhulu; njengoba izinga lamanzi lehla, cindezela phansi ipulasitiki elizungezile ngothi lomshanelo ukuze amaphakethe avaleleke agelezele ebhakedeni.
• Uma amanzi ehlanganise kokubili PHEZU KWAKHO NAPHANSI kweshidi lepulasitiki: Ngaphandle kwalapho i-crawlspace inolayini ovala omhlophe ovalwe kahle oqinile ngokuphelele, indlela eshesha kakhulu yokukhipha umgoqo womhwamuko wepulasitiki omnyama ogcwele izikhukhula uwukusika 30-centimeter (12-intshi) X-fourning engxenyeni engezansi kwesokudla sepulasitiki ngalinye i-crawlspace ukuze amanzi adlulele ngaphezulu nangaphansi kwesivimbelo aye endaweni eyodwa. (Uma isikhukhula sihilela amanzi angaphansi komhlaba anodaka noma indle, ishidi lepulasitiki elingcolile elingu-6-mil kufanele likhishwe futhi esikhundleni salo kufakwe i-polyethylene entsha engu-6-mil ukuya ku-12-mil ngemva kokuba inhlabathi yomile noma kunjalo.)

3. Umthetho Obalulekile Wokuphepha Ohamba Ngokuhamba: Ungalokothi Umbe Imbobo Ejulile Engalayishiwe Eceleni Kodonga Lwesisekelo noma Isigxobo Sezitini¶

Uma abanikazi bezindlu befuna ukuthola amasentimitha angu-5 (amayintshi angu-2) wokugcina wamanzi endaweni yokukhasa engcolile, bavame ukulingeka ukuba bathathe ifosholo bese bemba umgodi ongamasentimitha angu-45 ukujula (ongamayintshi angu-18-intshi) eduze komgodi webhulokhi kakhonkolo noma udonga lwesisekelo lwangaphandle ukuze bawise iphampu. - Kungani ukumba eduze nendawo kubangela ukuxazululeka kwesakhiwo: Izinyawo eziyisisekelo zisabalalisa isisindo sendlu yakho phansi nangaphandle emhlabathini kwikhoni ethwala umthwalo engama-degree angu-45 (indawo yethonya). - Uma umba umgodi we-sump eduze kuka amasentimitha angu-60 (amayintshi angu-24) endaweni engashoni yomgodi wokucasha noma unyawo lodonga oluzungezayo, inhlabathi emanzi esuka ngaphansi konyawo lukakhonkolo ishona emaceleni ingene emgodini wakho, okubangele ukuthi indawo yomgodi izike futhi iqhekeze udonga olomile namafreyimu eminyango kuyo yonke indlu phezulu. Hlala njalo thola noma yikuphi ukucindezeleka kwe-sump okungenani amasentimitha angu-60 ukuya kwangu-90 (amafidi angu-2 ukuya kwangu-3) ukusuka kunoma iyiphi indawo yokhonkolo noma isigxobo sokusekela bese uyibeka ngesitsha sepulasitiki esinezimbobo esizungezwe ngamatshe ahlanziwe.

I-Deep dive 4: Ukuvimbela isikhunta samahora angu-72 kanye nebhomu lesikhathi sokubola kwezinkuni ngemva kokupompa¶

Uma ama-puddles amile esekhishiwe, isimo esiphuthumayo siphelile. Iphansi elimanzi le-crawlspace kanye ne-subfloor yokhuni ecwilisiwe ehlezi endaweni emnyama, emoyeni omile engu-20 degrees Celsius (68 degrees Fahrenheit) izoqhuma kusikhunta esimhlophe nesimnyama esinama-filamentous (Aspergillus, Penicillium, Cladosporium, ne-Stachybotrys) phakathi** namahora angu-48 kuya kwangu-72**. Ngoba umoya ofudumele ukhuphuka ngaphakathi endlini (umphumela westaki wemvelo), amaphesenti angu-40 kuya kwangu-50 omoya owuphefumulayo esitezi sokuqala sendlu yakho adonselwa phezulu ngokuqondile ngokungena phansi kusuka endaweni yokukhasa.

Isinyathelo Ngesinyathelo Ngemuva Kwezikhukhula I-Crawlspace Drying & I-Wood-Rot Prevention Protocol¶

1. Isinyathelo 1 (Khipha Konke Okuwayo noma Okumanzi I-Fiberglass Batt Insulation Ngokushesha):
2. Gqoka NIOSH N95 noma P100 particulate respirator, izibuko zokuphepha, amagilavu ​​aminyene e-nitrile/rabha, kanye nemikhono emide.

Kungani ungakwazi ukonga i-subfloor fiberglass emanzi: Ngisho nangemva kwenyanga yokugijima kwabalandeli, amalulwane e-fiberglass acindezelwe ngokumelene nama-joists okhuni abamba ifilimu elincanyana lamanzi aluketshezi ngokumelene nebhodi le-strand oriented (OSB) noma i-plywood subfloor. Ukushiya i-fiberglass emanzi endaweni kuqinisekisa ukuthi ama-joists aphansi okhuni kanye ne-subfloor izobola futhi idinga amashumi ezinkulungwane zamaRandi emsebenzini wokubaza wesakhiwo (ukugoqa kwe-subfloor kanye namajoists abolile).
5. Isinyathelo 2 (Khipha noma Ukhiphe Ipulasitiki Ehlanganiswe Ngodaka engu-6-Mil bese Umboza Udaka Olumanzi Olungenalutho):
6. Udaka lwe-crawlspace olucwilisiwe lukhipha izinkulungwane zamalitha amanzi emoyeni njengoba loma.
7. Uma wonke amachibi amile engasekho, uma iphansi eliwubhuqu lingenalutho olumanzi, gingqa ishidi lepulasitiki le-polyethylene lesikhashana elishibhile elingu-6-mil phezu kodaka olumanzi ngaso leso sikhathi. Ukumboza ukungcola okumanzi phansi ngepulasitiki ngokushesha kuvimbe umhlaba ekuhwamuliseni umswakama ongapheli emoyeni we-crawlspace, okuvumela abalandeli bakho nezinto ezikhipha umswakama ukuthi zome izihlanganisela zaphansi zokhuni kanye ne-subfloor** ngokushesha okuphindwe ka-5.
8. Isinyathelo sesi-3 (Ukugeleza komoya Okwesivinini Esikhulu + Ukususwa Komswakama Kwendawo Evaliwe Ye-Crawl):
9. Umthetho Wesithupha Wokungenisa umoya vs. Ukususa umswakama:
   • Uma isimo sezulu sangaphandle sipholile futhi somile amathambo (Iphoyinti Lamazolo Langaphandle lingaphansi kuka-10°C / 50°F): Vula izimbobo ze-crawlspace bese ubeka i-CFM ephezulu i-carpet blower (i-air-mover) noma ifeni yebhokisi elisindayo ku-crawlspace access hatch ekhomba NGAPHANDLE (umoya wokukhasa oqeda amandla ngaphandle). Umoya okhathazayo ophumela ngaphandle udala ingcindezi negetive ethambile ngaphakathi kwendawo yokukhasa ukuze kumanzi, iphunga le-musty crawlspace kanye nezinhlamvu zesikhunta zidonselwa ngaphandle kunokuba ziphushelwe phezulu egumbini lakho lokuhlala.
   • Uma isimo sezulu sangaphandle sifudumele futhi sinomswakama (Isimo Sezulu Sasehlobo / Intwasahlobo / Esinomswakama): Ungaphephuleli kushisa, onomswakama wamaphesenti angu-75-umswakama wangaphandle emoyeni endaweni epholile yokukhasa, noma umswakama uzofingqa kuzo zonke izihlanganisela zaphansi ezipholile futhi wenze isikhunta sibe sibi nakakhulu. Esikhundleni salokho, vala izimbobo zangaphandle ze-crawlspace kanye nokuchanyuselwa, setha amafeni anyakazayo angu-2 noma 3 ngaphakathi kwendawo yokukhaka eqondiswe phezu kwezihlanganisi zokhuni ezingenalutho ukuze kwephule ungqimba lomswakamo womngcele, futhi usebenzise i-high-capacity compressor dehumidifier (noma eqashiwe yokuthengisa i-LGR dehumidifier) edonsa ngepayipi ukuya endaweni engaphandle*- cindezela amaphini okhuni kuze kube yilapho umswakama ucindezela iphini elingaphandle* i-subfloor ifundeka kanje ngaphansi kwamaphesenti angu-15 kuya kwangu-16 Okulingana Nomswakama Wezinkuni (WME) (isikhunta esibolayo asikwazi ukukhula lapho umswakama wokhuni ugcinwa ungaphansi kwamaphesenti angu-19, futhi ukukhula kwesikhunta kuyama lapho umswakama ohlobene uhlala ngaphansi kwamaphesenti angu-55).
10. Isinyathelo sesi-4 (Sebenzisa Isilondolozi Sezinkuni Se-Borate / Isikhunta Esibhalisiwe E-EPA kumaJoists Aveziwe):
11. Uma ama-joist angenalutho aphansi kanye ne-subfloor sekudaluliwe futhi komiswa, fafaza izindawo zokhuni ezingavuthiwe ngesisombululo se-disodium octaborate tetrahydrate (DOT / borate)* noma ukwelashwa okubhalisiwe kwe-EPA-nemithi yokukhunta usebenzisa isifutho sephampu engadini. Ama-Borate asakazeka ajule ezingodweni ezimanzi futhi avikele unomphela izihlanganisi zaphansi kukho kokubili isikhunta esibola izinkuni (ukubola okunsundu / ukubola okomile) kanye nemihlwa engaphansi komhlaba / izintuthwane zombazi (uswebezane lomhlwa nokwehluleka kwemishayo yesakhiwo).

Izinombolo zezimo eziphuthumayo zesifunda kanye nezinqubomgomo ze-ejensi¶

Uma izikhukhula ze-crawlspace zihlanganisa izingozi zikagesi, ukucekelwa phansi kwesisekelo sesakhiwo, noma ukungcoliswa kwendle:

• I-United States neCanada: Shayela u-911* (bona izinombolo eziphuthumayo) ngokushesha nganoma yikuphi ukushaqeka kukagesi, iphunga legesi, noma ukuvaleka kwendawo. Ukomiswa kwesakhiwo sangemva kwezikhukhula, ukulungisa isikhunta, kanye nesigaba ½/3 samanzi kulandela ANSI/IICRC S500 (Okujwayelekile Kokubuyiselwa Kokulimala Kwamanzi Okuphrofeshinali), ANSI/IICRC S520 (Ukulungiswa Kwesikhunta), Ibhulethi Yezobuchwepheshe ye-FEMA 1 & 2, kanye U I-EPA isiqondiso sokulawula umswakama.
• E-United Kingdom: Shayela u-999* ngezimo eziphuthumayo zikagesi noma zesakhiwo, noma 105 ukuze unqamule amandla. Emakhaya ase-UK* anezitezi ezimisiwe ezimisiwe (ama-sub-floor voids)**, izindawo zokungena komoya kanye nezindawo zokuvikela umswakama (i-DPC) (ubuncane be-150 mm ngaphezu kweleveli yangaphandle yaphansi) kanye nokungena komoya ngezitini kulawulwa Imithetho Yokwakha Evunyiwe Umbhalo C kanye **BS 5250Esakhiweni(Ukuphathwa Kwesakhiwo)
• I-European Union: Shayela u-112* ukuze uthole impendulo ephuthumayo. Ukuphepha kukagesi ngaphansi kwesitezi kudinga 30 mA Ukuvikelwa Kwedivayisi Yamanje eyinsalela (RCD) ngaphansi kwe-IEC 60364.
• I-Australia ne-New Zealand: Shayela u-000* e-Australia noma 111 eNew Zealand. Ukucaciswa kwe-Subfloor, i-ant-capping (izihlangu zomuhlwa), kanye nezimfuneko zokungena komoya phakathi kwe-subfloor zilawulwa ngaphansi kwe-National Construction Code (NCC / BCA) kanye ne-AS 3660.1 (Termite Management), njengoba ama-subfloor angaphansi kuyiwona okhanga umuhlwa ama-Coptoterme angaphansi komhlaba abhubhisayo.
• I-India ne-Asia-Pacific: Shayela u-112* e-India noma 119 e-Japan naseNingizimu Korea. E-Japan (yukashita shinsui - izikhukhula ezingaphansi), izikhungo zezempilo zikamasipala (Hokenjo) zihlinzeka nge-hydrated lime (shosekkai) kanye nezinqubo zokubulala amagciwane e-benzalkonium chloride ngemva kwesishingishane noma imvula enamandla engaphansi komhlaba.

Imibuzo ejwayelekile ukubuzwa¶

Ingabe kuphephile ukukhasa endaweni yokukhasa enamanzi amile uma ngigqoke amabhuzu emvula erabha?¶

Cha, ungalokothi ungene endaweni yokukhasa emanzi noma egcwele amanzi ngenkathi ugesi wasendlini usakhanyisiwe, ngisho noma ugqoke amabhuzu enjoloba. Ngokungafani nokuhamba uqondile emanzini angashoni, ukungena endaweni yokukhasa engamasentimitha angu-60 ukuphakama (24-intshi-ukuphakama) kukuphoqa ukuthi ungene ezandleni zakho, emadolweni, nasesiswini lapho izindololwane zakho, amahlombe, noma ikhanda lakho likwazi ukuxubha kalula ocingweni oluphilayo lwamavolthi angu-120 noma angu-240-volt, ipayipi lokushisisa lensimbi elingagxiliwe, ipayipi lamanzi eliwele phezulu, noma ibhokisi lokuphambana kwamanzi. Ngaso sonke isikhathi phequlula i-Main 100A/200A I-Service Breaker ukuze indlu yonke IYAVALE kuphaneli kagesi ngaphambi kokuwela umkhawulo we-crawlspace.

Kuthatha isikhathi esingakanani ukuthi amanzi amile endaweni yokukhasa abangele isikhunta kumajoists aphansi noma abolise i-subfloor?¶

Esimweni sezulu esifudumele noma esinesimo sezulu esipholile esingaphezu kuka-15 degrees Celsius (60 degrees Fahrenheit), izinhlamvu zesikhunta ziba khona ngokwemvelo ekuhlanganiseni okuluhlaza kwamapulangwe kanye nasezindaweni ezingaphansi zeplywood ziqala ukuhluma futhi zenze amakoloni abonakalayo afiphele phakathi kwamahora angu-48 kuya kwangu-72 ngemva kokuba umswakama ohlobene nendawo ye-crawlspace ungaphezu kwamaphesenti angu-70 ukuya kwangu-80. Isikhunta sesakhiwo esibolayo sokhuni (ukubola okunsundu nokubola okumhlophe) sidinga umcu wokhuni ngokwawo ukuthi ufinyelele umswakama ongaphezu kwamaphesenti angu-20 (iphoyinti lokugcwala kwe-fiber cishe ngamaphesenti angu-28), okwenzeka phakathi nesonto eli-1 kuya kwangu-2 uma ukufakwa kwe-fiberglass emanzi kushiywe kucindezelwe okhunini noma uma amanzi amile ehlala engampompi ngaphandle komgoqo womhwamuko.

Ingabe kufanele ngivule izikhala zami zesisekelo se-crawlspace ehlobo ukuze ngomise indawo yokukhasa emanzi noma emanzi?¶

Vula kuphela izikhala ze-crawlspace uma umoya wangaphandle womile kunomoya we-crawlspace (ikakhulukazi, lapho izinga lokushisa langaphandle lendawo yamazolo liphansi kunezinga lokushisa elingaphakathi kwendawo yakho epholile, njengasekwindla elipholile, elomile noma usuku lwasentwasahlobo). Ngesikhathi sezulu sasehlobo esishisayo, esimangelengele, umoya wangaphandle ongu-30 degrees Celsius (86 degrees Fahrenheit) kanye nomswakama ongamaphesenti angu-70 ubamba inani elikhulu lomhwamuko wamanzi; lapho lowomoya oshisayo wangaphandle oshisayo ugeleza ezindaweni ezivulekile zesisekelo uye endaweni epholile enomthunzi ongu-18-degree-Celsius (65-degree-Fahrenheit) enomthunzi, umswakama wawo ukhuphuka ufike kumaphesenti angu-100 bese ujiya ube amaconsi amanzi awuketshezi kuwo wonke amapayipi omoya abandayo, amapayipi amanzi, nezixhumi zokhuni zaphansi. Ngemva kokumpompa amanzi amile esimweni sezulu sasehlobo esiswakeme, vala ukungcola okumanzi ngepulasitiki engu-6-mil, vala izintuba zangaphandle, bese womisa isikhala ngamafeni kanye nesiqeda manzi esivaliwe.

Ngiyihlanza kanjani futhi ngibulale amagciwane endaweni yokukhahlela uma ipayipi lendle liphuka futhi kuchitheke indle eluhlaza ngaphansi kwendlu?¶

Ukuchitheka kwendle okungahluziwe ngaphakathi kwe-crawlspace kuyingozi Yesigaba 3 sebhayoloji equkethe amagciwane e-pathogenic (E. coli, Salmonella), amagciwane, nezimuncagazi. Ungalokothi ungene ngaphandle kwe-P100/N95 respirator, izibuko zamehlo ezivaliwe, amagilavu ​​aqinile angangeni manzi, kanye nesudi yeTyvek ene-hood elahlwayo. Ngemva kokuba osebenza ngamapulangwe elungise ipayipi eliphukile lensimbi noma ipayipi le-PVC lokudonsa bese empompa indle ewuketshezi endaweni yokuhlanza, kufanele ukhiphe futhi ulahle zonke izithiyo zomphunga wepulasitiki ezingcolile kanye nokufakwa kwensimbi okuwile, ukhiphe imfucumfucu eqinile, ufafaze yonke inhlabathi ethintekile kanye nezinkuni kahle ngesibulala-magciwane esibhaliswe yi-EPA esikhungweni se-limeor esisakazwayo nesibulala-magciwane se-pH esine-limeor. cindezela iphunga/amagciwane), sula isikhala ngokuphelele ngamafeni akhipha umoya ongemuhle, futhi ubeke umgoqo womhwamuko we-polyethylene omusha sha we-6-mil kuya ku-12-mil.

Ingabe amanzi amile endaweni yokukhasa angalimaza isisekelo sikakhonkolo sasekhaya noma abangele ukuwohloka kwaphansi?¶

Yebo, amanzi amile isikhathi eside endaweni yokukhasa asongela isakhiwo sendlu ngezindlela ezimbili. Okokuqala, ngaphansi kwenhlabathi, amanzi amile athambise ubumba olunwetshiwe kanye nodaka ngokuqondile ngaphansi kwamaphedi kakhonkolo angajulile (izinyawo) abamba izinsika zezitini ezimaphakathi noma izigxobo zokusekela zokhuni, okubangela ukuthi lezo zinsimbi ezimaphakathi zicwile odakeni futhi zidale ukucwiliswa okubonakalayo noma ukugoba okugobile phansi kwephasishi elimaphakathi lendlu. Okwesibili, ngaphezu kwamanzi, umswakama oqhubekayo ongamaphesenti angu-90 ukhuphula umswakama wezingcwecwe zokhuni, i-main girder beam, nezixhumi zaphansi ezingaphezu kwamaphesenti angu-20, okuvumela isikhunta esibola izinkuni kanye nomuhlwa ongaphansi komhlaba ukuba udle amandla okuthwala amapulangwe.
