1. Yakavanzika Magetsi Energization Sources Mukati Yekugara Crawlspace¶

Kunyangwe kana main breaker panel yako iri kumusoro mugaraji kana mukoridhe, anenge ese emagetsi edunhu mu crawlspace-foundation imba inomhanya yakachinjika kuburikidza ne crawlspace pazasi pemapuranga epasi joists: - Sumpmerged Crawlspace Sump Pumps uye HVAC Condensate Pumps: Aya plug mumidziyo ye120V yakaiswa pasi pamapuranga emapuranga kana madziro ekongiri, kazhinji angori 20 masendimita (8 inches) kubva pasi pevhu. - ** Fallen Junction Mabhokisi neRomex Splice Mabhokisi**: Dzimba dzechikuru dzinogara dziine mabhokisi esimbi asina kufukidzwa akarembera newaya dzawo mushure mekunge zvipikiri zvine ngura zvaburitswa kunze kwekunyorovesa majoists, kana tambo dzeRomex dzakatsenga dzakazorora dzakananga papfuti yepurasitiki. - Energized Sheet-Metal HVAC Ductwork and Copper Water Pipes: Kana tambo yakapwanyika ye120V yechoto inofuridza kana waya yekupisa mvura ikagunzva simbi yekudziisa trunk duct kana pombi yemhangura, iyo yose metal ductwork network uye pombi dzemvura mu crawlspace inogona kutakura mhenyu 120-volt kana imba yakavharwa nemagetsi - ** Safety Rule**: Flip iyo Main Service Breaker kuti DZIMA pabhokisi rako rekupwanya usati waongorora. Kana iwe uchida simba replug-in kuti umhanye pombi yekushandisa inonyudza kana yekunyorova/yakaoma shopu vacuum, mhanyisa basa rinorema 12-gauge yekunze tambo yekuwedzera kubva pane yakatarisana chimiro kana inotakurika jenareta kuburikidza neplug-in GFCI (Ground Fault Circuit Interrupter / RCD) adapta usati wadzoreredza imwe imba yekurara* yakaomeswa simba* ine GFCI tambo adapta yakabatanidzwa mairi.

2. Confined-Space Atmospheric Hazards (Sewer Gasi, Carbon Monoxide, uye Fuel Leaks)¶

Nzvimbo ine mafashama e crawlspace ine yakavharwa nheyo dzemhepo ine inenge zero mhepo kuchinjanisa: - Gasi Rezvakasikwa / Propane Pooling: Propane inorema kudarika mweya (chaiyo giravhiti 1.52) uye inonyura yakananga kwakadzikira kwenzvimbo ye crawlspace kana mutsetse wakaora wesimbi kana gasi remhangura ukadonha. Kana iwe ukanhuwa mazai akaora, petroleum, kana gariki pamusuwo we crawlspace, buda uye ufonere 911. - Mbira / Mvura Heater Flue Backdrafting: Kana choto chakachinjika chinokambaira kana chinodziya chemvura chikagara mumvura iri kukwira, chinopisa chayo kana hood inogona kufashamira nekuteura inouraya carbon monoxide (CO) mugomba recrawlspace. - Hydrogen Sulfide neMethane kubva muSewage kana Rotting Organics: Mabhaudhi etsvina akamira anoburitsa hydrogen sulfide (H2S) muhomwe.

Yakadzika dive 2: Kuenzanisa matrix ye 4 crawlspace mvura zvitubu uye maitiro ekuzvisiyanisa.¶

Usati wamisa mafashamo zvachose, unofanira kuziva kana mvura iri pasi pemba yako iri kubva kumukati mepombi dzemvura kana kunze kwenheyo yako:

Yakadzika dive 3: Maitiro ekupomba kunze kwakazara mafashama crawlspace zvakachengeteka pasina kuyamwa madhaka, pepa repurasitiki, kana ivhu retsoka.¶

Kupomba mvura yakamira kubva muvhu-pasi kana mhute-barrier crawlspace kwakasiyana zvachose nekupomba imba yepasi kongiri. Kana ukangodonhedza pombi inonyura pauriri hwe crawlspace, zvinhu zviviri zvinoshata mukati memasekonzi gumi: kungave kukweva kwepombi kunokweva polyethylene yepurasitiki mhute inovharira pazasi pesikirini inopinza uye inopisa mota, kana pombi inonyura mumatope akapfava, inovhara chidziviriro chayo nevhu nevhu, uye inorovera padivi pegumbo rekongiri.

1. Vaka Yakagadziridzwa "Bucket Sump Screen" mu3 Maminitsi¶

1. Tora muyero 20-litre (5-gallon) epurasitiki bucket woboora makumi maviri kusvika makumi matatu 6-to-10-millimeter (¼-to-⅜-inch) maburi kumativi ** epakati nepamusoro** emugomo (siya pasi 5 masendimita / 2 inches mudhaka mudhadha haikwanise kutenderera).
2. Kana uine hwindo rekuvheneka kana jira rehardware riri padyo, riputire kunze kwebhaketi netape tepi kuti tambo dzefiberglass dzirambe dzakayangarara kubva mumakomba.
3. Isa ** flat kongiri paver zvidhinha kana patio dombo ** mukati mepasi pemugomo kuti uremerwe, uye isa yako ** submersible utility pombi (kana sump pump) ** pamusoro pezvidhinha mukati memugomo.
4. Batanidza 32-millimeter (1-¼-inch) corrugated sump discharge hose (inopomba nekukurumidza katatu pane yakamanikana yepaipi yebindu) kana inorema-basa 19-millimeter (¾-inch) hose yebindu kune pombi yekubudisira, uye mhanyisa panobuda pombi kusvika pamamita matanhatu kubva paimba kusvika pamamita 10 zvichidzika kubva pamamita mashanu. materu kuitira kuti mvura irege kungonyura nemadziro enheyo muchitsiko chinoenderera.
5. Kanda bhaketi mugomba rakadzika mukati menzvimbo inokambaira uchishandisa danda refu kubva panochochonywa, wovharira pombi mu GFCI-inochengetedzwa yekubuda KUNZE kwenzvimbo inokambaira.

2. Kuchera Mvura Yakavharirwa PAMUSORO PA vs. PASI pePlastic Vapor Barrier¶

• Kana mvura yaiswa PAMUSORO PEPlastiki yepolyethylene: Pepa repurasitiki rinoyangarara richienda kumusoro richiita mikumbiro uye richiteya madziva emvura akaparadzana pakati pemakwinya. Seta yako uremu perforated pombi bucket zvakananga pamusoro pepurasitiki pepa mukuderera kuderera; mvura painodzikira, dzvanya purasitiki rakatenderedza pasi nechimuti chemutsvairo kuitira kuti homwe dzakavharirwa dziyerere dzichienda kumugomo.
• Kana mvura yaungana zvese PAMUSORO NEPAPASI pepurasitiki pepa: Kunze kwekunge crawlspace iine chena yakavharidzirwa yakavharidzirwa liner iyo yakazara zvachose, inokurumidza nzira yekubvisa mafashama yakajairwa 6-mil nhema yepurasitiki vapor barrier ndeyekucheka ** 30-centimita (12-inch) X-yakatsemurwa pakona yekurudyi yepurasitiki* pakona yekurudyi* crawlspace kuitira kuti mvura pamusoro uye pazasi pechivharo ichiyerera munzvimbo imwechete. (Kana mafashamo aisanganisira mvura yepasi ine madhaka kana tsvina, pepa repurasitiki rine 6-mil rine utachiona rinofanirwa kudhonzwa kunze rotsiviwa neratsva 6-mil kusvika 12-mil polyethylene mushure mekunge ivhu raoma zvakadaro.)

3. Yakakosha Yetsoka Yekuchengetedza Rule: Usambochera Gomba Rakadzika Risina Mutsetse Padyo NeRusvingo Rwenheyo kana Chidhinha¶

Kana varidzi vedzimba vachida kutora masendimita mashanu ekupedzisira emvura kubva munzvimbo ine tsvina, vanowanzoedzwa kutora foshoro uye kuchera gomba rakadzika masendimita 45 (18-inch-yakadzika) pedyo nepier yekongiri kana kuti madziro enheyo yekunze kuti adonhedze pombi mukati. - Nei kuchera padivi pechitsiko kuchikonzera kugadzirisa kwemaitiro: Nheyo dzenheyo dzinogovera huremu hwemba yako pasi nekunze kuburikidza nevhu mu 45-degree-45-degree-loading-bearing cone (zone of influence). - Kana ukachera gomba riri pedyo nekupfuura masendimita makumi matanhatu (24 inches) kune isina kudzika crawlspace pier tsoka kana perimita yemadziro tsoka, ivhu rakanyura kubva pasi pekongiri yetsoka inonyura nedivi mugomba rako, zvichiita kuti pier inye uye kutsemuka madziro akaoma nemafuremu emusuwo mumba mese pamusoro. Gara uchitsvaga chero sump depression ** ingangoita 60 kusvika 90 centimita (2 kusvika 3 tsoka) kubva kune chero kongiri tsoka kana positi yekutsigira ** woimisa neine perforated yepurasitiki sump bheseni yakakomberedzwa nematombo akagezwa.

Yakadzika dive 4: Kudzivirira iyo 72-awa mold uye huni-kuora nguva bhomba mushure mekupomba¶

Kana madhiri akamira aburitswa, chimbichimbi chinongodarika hafu. Uriri hwevhu hwakanyorova uye nematanda akanyorova agere murima, mweya wakamira pa20 madhigirii celsius (68 madhigirii Fahrenheit) anobuda muchena uye dema filamentous mold (Aspergillus, Penicillium, Cladosporium, uye Stachybotrys) mukati 48 kusvika 72 maawa. Nekuti mweya unodziya unokwira mukati memba (** the natural stack effect**), **40 kusvika 50 muzana yemhepo yaunofema pauriri hwekutanga hwemba yako inodhonzwa yakananga kumusoro kuburikidza nekupinda pasi kubva panzvimbo inokambaira **.

Mibvunzo inowanzo bvunzwa¶

Zvakachengetedzeka here kukambaira munzvimbo ine mvura yakamira kana ndikapfeka bhutsu yerabha?¶

Aiwa, usambokambaira munzvimbo ine mvura kana kuti ine mafashama apo magetsi emba achiri akabatidzwa, kunyangwe wakapfeka bhutsu dzerabha. Kusiyana nekufamba wakatwasuka mumvura isina kudzika, kupinda munzvimbo ine 60-centimeter-high (24-inch-high) crawlspace inokumanikidza kuti upinde mumaoko ako, mabvi, uye mudumbu apo magokora ako, mapfudzi, kana musoro wako unogona kukwesha nyore nyore pawaya mhenyu 120-volt kana 240-volt, simbi isina kuvhurika inodziya mugero, pombi yemvura yemhangura yakadonha, kana bhokisi remvura.
