Kuthatha isikhathi esingakanani ukuthi ukhonkolo wome?

Umhlahlandlela Ophelele Wokomisa Nokuphola Kwekhonkrithi: Kusukela Ekutheleni Kuze Kube Amandla Aphelele

Ukhonkoloingenye yezinto zokwakha ezisetshenziswa kakhulu emhlabeni jikelele, eyaziswa ngokuqina kwayo, ukuguquguquka kwayo, kanye nokusebenza kwayo kahle. Kodwa-ke, ukusebenza kwayo kuncike ekomiseni nasekulungiseni kahle—izinqubo ezivame ukungaqondwa kahle noma ezihlanganiswa. Lo mhlahlandlela onamagama angu-3,000 ugxila kwisayensi, izikhathi, kanye nemikhuba emihle yokomisa ukhonkolo, ukuphulukisa, kanye nokufeza amandla afanele.

1. Ukuqonda "Ukomisa" Okukhonkolo vs. Ukulungisa

Ngaphambi kokuhlola izikhathi, kubalulekile ukuhlukanisa phakathiukomisa(ukuhwamuka kwamanzi) kanyeukwelapha(ukumanzisa usimende).

• Ukomisa: Kubhekisele ekuhwamukeni kwamanzi angaphezulu avela ebusweni bekhonkrithi. Nakuba umswakama womphezulu ungase unyamalale phakathi namahora, umswakama wangaphakathi ungahlala amasonto.
• Ukwelapha: Inqubo yamakhemikhali lapho amanzi ehlangana nezinhlayiya zesimende (ukumanzisa), akha izibopho eziqinisa ukhonkolo. Ukuqina okufanele kuqinisekisa amandla, ukuqina, kanye nokumelana nokuqhekeka.

Ukuthatha Okubalulekile: Ikhonkrithi “ayilomisi” ngomqondo wendabuko—iyaphola ngokuswakama, okudinga ukugcinwa komswakama.

2. Izigaba Zokubeka Nokuqinisa Ukhonkolo

Isikhathi kusukela ekuthululweni kuya emandleni aphelele sihilela izigaba ezihlukene:

Isigaba 1: Isethi Yokuqala (Amahora angu-2–6)

• Ukuguquka kwekhonkrithi kusuka koketshezi kuya kokuqina okuncane.
• Ukuhamba ngezinyawo: Ukuhamba ngezinyawo okuncane kungenzeka ngemva kwamahora angu-24-48.

Isigaba 2: Isethi Yokugcina (Amahora angu-6–12)

• Ubuso buqina ngokwanele ukumelana nokubhoboka okuncane.
• Ifomu lingasuswa, kodwa ukhonkolo uhlala usengozini.

Isigaba 3: Amandla Okuqala (Izinsuku eziyi-1–7)

• Ifinyelela cishe ku-70% wamandla okuklama ezinsukwini eziyi-7 (ezixubeni ezijwayelekile).
• Kuphephile ezimotweni ezilula (isb., ezimotweni) ngemva kwezinsuku eziyi-7.

Isigaba 4: Ukwelashwa Okugcwele (Izinsuku ezingu-28)

• Izinga lemboni "lamandla aphelele" (amandla okuklama angu-100%).
• Imishini esindayo kanye nemithwalo yesakhiwo iyavunyelwa.

Isigaba 5: Ukumanzisa Kwesikhathi Eside (Izinyanga Kuya Eminyakeni)

• Ikhonkrithi iyaqhubeka nokuqina ngesivinini esiphansi iminyaka eminingi.

3. Izici Ezithonya Isikhathi Sokomisa Nokuphola

Izikhathi ziyahlukahluka ngokuya ngezimo zemvelo, ukwakheka okuxubile, kanye nemininingwane yephrojekthi:

A. Izici Zemvelo

1. Izinga lokushisa:
   • Ibanga Elifanele: 50–90°F (10–32°C).
   • Isimo Sezulu Esibandayo (<50°F): Kunciphisa umswakama; kudinga ukufudumala noma izindawo zokuvala ezifudumele.
   • Isimo Sezulu Esishisayo (>90°F): Kusheshisa ukoma kwendawo, kubeke engcupheni imifantu. Sebenzisa i-misting noma umthunzi.
2. Umswakama:
   • Umswakama ophezulu unciphisa ukuhwamuka kwamanzi, okusiza umswakama.
   • Umswakama ophansi usheshisa ukoma kwendawo, okudinga ulwelwesi oluqinile.
3. Umoya: Kwandisa amazinga okuhwamuka kwamanzi, okuholela ekuqhekekeni kwepulasitiki.

B. Umklamo Wokuxuba Ukhonkolo

1. Isilinganiso Samanzi Nesimende: Izilinganiso eziphansi (0.4–0.6) zisheshisa ukwanda kwamandla kodwa zidinga ukuqiniswa ngokucophelela.
2. Izingxube:
   • Izisheshisi(isb., i-calcium chloride): Nciphisa isikhathi sokusetha.
   • Abahlehlisi: Ukubeka isikhathi sokubambezeleka ezindaweni ezishisayo.
   • Ama-Pozzolans(umlotha wempukane, i-silica fume): Ithola amandla kancane kancane kodwa ithuthukisa ukuqina kwesikhathi eside.
3. Uhlobo Lwekhonkrithi:
   • Ukhonkolo Onamandla Aphezulu Esikhathini Esidlule: Ifinyelela ama-psi angu-3,000 emahoreni angu-24.
   • Izingxube Ezijwayelekile: 3,000–4,000 psi ezinsukwini ezingama-28.

C. Imininingwane Yephrojekthi

1. Ubukhulu be-Slab: Izingxenye ezijiyile zigcina umswakama isikhathi eside, okwenza kube lula ukoma kwendawo.
2. Ukuqinisa: I-rebar yensimbi noma i-mesh ingase ibambe umswakama, ithinte ukufana kokuqiniswa.

4. Izindlela Zokwelapha Ukuze Uthuthukise Amandla

Ukwelapha kugcina umswakama ukuze kutholakale amanzi. Amasu avamile afaka:

1. Ukwelapha Amanzi:
   • Ukumboza ngendwangu, ukufafaza, noma ukumanzisa izembozo ze-burlap (okungenani izinsuku ezingu-7).
   • Kuhle kakhulu ezintweni zesakhiwo ezifana nemishayo namakholomu.
2. Izinhlanganisela Ezakha Ulwelwesi:
   • Izinto zokuvala ezifuthwayo zinciphisa ukuhwamuka kwamanzi.
   • Isetshenziselwa ama-slab kanye nama-pavement.
3. Ukumboza ngepulasitiki/amathayi:
   • Ibamba umswakama; idinga ukumanziswa njalo.
4. Ukwelapha ngomusi:
   • Kusheshisa ukutholakala kwamandla kukhonkrithi elungisiwe (isb., amahora angu-18-24).

5. Ukuhlola Ukulungela Ukhonkolo

1. Ukuhlolwa Kokuqina Komphezulu:
   • Ukuhlolwa Kwezithupha: Akukho ukujiya ngemva kokucindezela ngesithupha.
   • Ukuhlolwa Kokuklwebha: Ukumelana nesikulufo noma isipikili.
2. Ukuhlolwa Kwamandla Okucindezelayo:
   • Amasampula esilinda ahlolwe ezinsukwini eziyi-7 nezingama-28 emalabhorethri.
3. Amamitha Omswakama:
   • Kala okuqukethwe komswakama wangaphakathi (<4% wokufakwa phansi).

6. Amaphutha Avamile Nokuthi Ungawagwema Kanjani

• Ukulayisha Ngaphambi Kwesikhathi: Gwema imithwalo esindayo ngaphambi kwezinsuku ezingu-28.
• Ukwelashwa Okunganele: Kuholela ekususeni uthuli, ekukhuleni nasekuncipheni kokuqina.
• Ukunisela ngokweqile: Kunciphisa ungqimba olungaphezulu.

7. Amacala Akhethekile kanye ne-FAQ

• Isimo Sezulu EsibandayoSebenzisa izingubo zokuvikela noma izivalo ezifudumalayo.
• Ukuchayeka emvuleni: Vikela ukhonkolo omusha ngama-tarps; imvula ngemva kwamahora angu-4-8 ayilimazi kangako.
• Amaphrojekthi AsheshayoSebenzisa izingxube ezinamandla kakhulu noma ukupholisa ngomusi.

UkhonkoloIsikhathi "sokomisa" sika sithatha amahora amaningi ukuze kuphume umhwamuko womphezulu kodwa sidinga izinsuku ezingama-28 ukuze kutholakale amandla okuklama. Ukuqina kahle akuxoxiswana ngakho ukuze kuhlale isikhathi eside, futhi izici zemvelo kumele ziphathwe ngokucophelela. Ngokuqonda isayensi yokudonsa amanzi nokusebenzisa imikhuba emihle kakhulu, osonkontileka kanye nabenzi be-DIY ngokufanayo bangaqinisekisa izakhiwo zekhonkrithi ezihlala isikhathi eside neziqinile.
