Indlela efanele yokudlidliza kanye nobuchwepheshe bekhonkrithi

Kuyini Ukudlidliza Kwekhonkrithi?

Ukudlidliza kwekhonkrithi kwenziwa ngenhloso yokuqinisa. Inhloso eyinhloko yokudlidliza ukuqiniswa kwekhonkrithi nokufeza ubukhulu obukhulu bekhonkrithi. Cishe u-5 kuya ku-8% wevolumu yekhonkrithi esanda kufakwa efomini ihlalwa amabhamuza omoya. Amabhamuza omoya ahlala kulesi sikhala ngengxube yekhonkrithi esebenza kahle kakhulu.

Ukudlidliza kokhonkolo

Isizathu kanye nendlela yokuhlanganisa ukhonkolo

Yisiphi isici esinomthelela omkhulu emandleni okucindezela ukhonkolo kunanoma yisiphi esinye? Iningi lonjiniyela lingathi isilinganiso samanzi nokhonkolo…njengoba isilinganiso samanzi nokhonkolo sanda amandla ayancipha. UDuff Abrams wabonisa lokhu ngo-1919, futhi umthetho ka-Abram uyisimiso ngemuva kwezindlela eziningi zokulinganisa ukhonkolo ezisetshenziswa namuhla. Kodwa u-Abtams wenza izivivinyo zakhe kukhonkolo ehlanganiswe ngokuphelele. Ngaphandle kokuthi ikhonkolo ihlanganiswe kahle, ama-voids anciphisa amandla kungakhathaliseki isilinganiso samanzi nokhonkolo. Futhi, njengoba kuboniswe kuMfanekiso 1, umphumela ubalulekile.

Ngemva nje kokufakwa kwayo, ukhonkolo uqukethe umoya ovalelekile ofika ku-20%. Inani liyahlukahluka kuye ngohlobo lokuxuba kanye nokuwa, usayizi wefomu kanye nesimo, inani lensimbi yokuqinisa, kanye nendlela yokufaka ukhonkolo. Ngesilinganiso esiqhubekayo samanzi nosimende, iphesenti ngalinye lomoya linciphisa amandla okucindezela cishe ngo-3% kuya ku-5%. Ukuhlanganisa ukhonkolo, ngokuvamile ngokudlidliza, kwandisa amandla ekhonkolo ngokuxosha umoya ovalelekile. Kuphinde kuthuthukise amandla e-sbond futhi kunciphisa ukungena kwekhonkolo.

Ukudlidliza kuyinqubo enezingxenye ezimbili

Ukudlidliza kuhlanganisa kanjani ukhonkolo? Isithombe 2 sibonisa ukuthi kuyinqubo enezingxenye ezimbili. I-vibrator idala amagagasi ahlukanisa izinhlayiya ezihlanganisiwe, okunciphisa ukungqubuzana phakathi kwazo.

Isithombe 1. Izinga lokuhlanganiswa lingaba nomthelela ofanayo emandleni okucindezela njengesilinganiso samanzi nosimende. Ikhonkrithi ephansi ingaqukatha umoya ovalelekile ofika ku-20% uma ibekwa.

Isithombe 2. I-vibrator ihlanganisa ukhonkolo ngenqubo enezingxenye ezimbili. Amagagasi okuqala ancibilikisa ukhonkolo ukuze ugeleze kangcono futhi amagagasi aqhubekayo akhipha amabhamuza omoya.

KULUNGILE

Ukungena okuqondile ngamasentimitha ambalwa ekuphakamiseni kwangaphambilini (okungafanele kube okuqinile okwamanje) kwezikhawu ezijwayelekile ezihlelekile kuzonikeza ukuhlanganiswa okwanele.

KUZOHLANGANISANA

Ukungena okungahleliwe kwe-vibrator kuzo zonke izingqimba nezikhala ngaphandle kokujula okwanele ngeke kuqinisekise ukuhlanganiswa okuseduze kwezingqimba ezimbili.

Amabhamuza omoya angasuswa ngokunciphisa inani lamanzi adingekayo, kodwa kuthinta ukusebenza kahle kwekhonkrithi. Ngakho-ke, ukudlidliza kwekhonkrithi kuyindlela kuphela efanelekile esiza ngaphandle kokuthinta izakhiwo kwekhonkrithi entsha. Ukudlidliza kuthinteka kuphela kukhonkrithi entsha exubile noma umuntu angasho kuze kube yileso sikhathi lapho ikhonkrithi inamandla okugeleza khona. Lesi sigaba sikhona ngaphambi kokuqala kokusetha kokuqala.

Ukuqiniswa kwekhonkrithi noma Ukudlidliza kwekhonkrithi kungenziwa ngezindlela ezinhlanu ezahlukene:
1- Ukudlidliza ukhonkolo ngaphakathi ngokufaka isidlidliza sangaphakathi esisindweni sikakhonkolo.
2- Ukudlidliza ukhonkolo ngenkathi ulungisa i-shuttering usebenzisa ama-vibrator e-Shutter formwork.
3- Ngokudlidliza yonke inqwaba yekhonkrithi usebenzisa itafula elidlidlizayo.
4- Ukudlidliza ukhonkolo ngaphandle kobuso kusetshenziswa ama-vibrators angaphezulu.
5- Ukudlidliza ukhonkolo kusetshenziswa izihluthuleli ze-rebar.

Ukudlidliza Kokhonkolo Amathiphu
1- Ungadlidlizi kakhulu ukhonkolo njengoba uvumela ingxube ukuthi iphuke futhi ihlukane. Futhi, ungadlidlizi kakhulu ukhonkolo ngoba umoya ungase ubanjwe ezingqimbeni ezingezansi zokufakwa kukakhonkolo, okuholela esakhiweni sekhonkolo esibuthakathaka esiphuka kalula ngokucindezela okuncane.
2- Indlela evame kakhulu nge-vibrator yangaphakathi ukukhipha i-vibrator kancane kancane, ngesivinini esingaba ngu-25mm intshi ngomzuzwana. Uma amabhamuza esavela njengoba i-vibrator yekhonkrithi ikhishwa, kudingeka ukudlidliza okwengeziwe.
3- Ukuze uvimbele ukuthi amalunga abandayo angenzeki ezingqimbeni zekhonkrithi njengoba lezi zithululwa ngengqimba entsha yengxube yekhonkrithi, qiniseka ukuthi ungena kahle ekuthululweni nge-vibrator bese uxuba ungqimba oluthululwe ngaphambilini nolusanda kufakwa.
4- Ukuze usebenze kahle kakhulu, sebenzisa ukunyakaza okuqondile kuphela lapho udlidliza ukuze kube nengxube efanayo ye-aggregate kanye nekhonkrithi. Ukunyakaza okuvundlile kungaholela ekusabalaleni okungalingani futhi kwandisa amathuba okuthi i-vibrator ibambeke ku-rebar noma insimbi yokuqinisa.
5- Gwema ukusebenzisa i-vibrator njengethuluzi lokubeka ukhonkolo ngoba ngeke ikhiqize indawo ehambisanayo futhi ingase inikeze nezinkinga ezengeziwe ngamandla nesakhiwo.
6- Sebenzisa uhlobo olufanele lwesidlidlizi sikakhonkolo kuye ngesakhiwo esakhiwe noma usayizi wendawo yokusebenza. Cabanga ukusebenzisa isidlidlizi sikakhonkolo esincane esilula emisebenzini emincane ukuze kube lula ukuphatha nokusebenza kahle.
7- Cabanga ngokuba nesipele isidlidlizi sikakhonkolo khona ukuze ube nethuluzi lesibili lokufaka esikhundleni ngokushesha uma elokuqala lihlangabezana nezinkinga ngesikhathi usemsebenzini.
