Isingeniso sokusetshenziswa kwe-rebar

I-Rebar: "Amathambo nemisipha" kumaphrojekthi wokwakha

I-Rebar, igama layo eligcwele elithi "hot-rolled ribbed steel bar", liqanjwe ngenxa yezimbambo ezisatshalaliswa ngokulinganayo ngobude bobuso bayo. Lezi zimbambo zingathuthukisa isibopho phakathi kwebha yensimbi kanye nokhonkolo, okuvumela zombili ukuthi zakhe into eqinile futhi zimelane ngokuhlanganyela amandla angaphandle. Njengento esemqoka ebalulekile kumaphrojekthi wokwakha, i-rebar isetshenziswa kabanzi futhi ibalulekile, futhi isebenza cishe kuzo zonke izixhumanisi kusuka engqalasizinda kuya ezakhiweni eziphakeme.

Inkambu yokwakhiwa kwezindlu

Ezakhiweni zomphakathi nezentengiso, i-rebar ifana “nohlaka lwamathambo”.

• Isisekelo nemishayo: Isisekelo, amakholomu athwala imithwalo, imishayo nezinye izakhiwo eziwumgogodla wendlu zidinga i-rebar ukuze kwakhiwe uhlaka lwamathambo ensimbi bese luthela ukhonkolo. Isibonelo, izindonga zokugunda kanye namakholomu efreyimu ezakhiwo zokuhlala eziphakeme kakhulu kufanele zithembele kumandla aphezulu we-rebar ukumelana nesisindo sesakhiwo ngokwaso kanye nemithwalo yangaphandle ukuvimbela ukuwohloka kwesakhiwo noma ukuwa.

• Iphansi nodonga: Imeshi yensimbi phansi kanye nezinsika zesakhiwo odongeni nazo zenziwe nge-rebar. Ingahlakaza ukucindezela phansi, inciphise ukwenzeka kwemifantu, futhi ithuthukise ubuqotho nokumelana nokuzamazama komhlaba kodonga.

Ukwakhiwa kwengqalasizinda

• Ubunjiniyela bebhuloho: Kungakhathaliseki ukuthi ibhuloho lomgwaqo onguthelawayeka, ibhuloho likaloliwe noma i-overpass, i-rebar isetshenziswa kakhulu ezingxenyeni ezibalulekile njengezinsimbi zamabhuloho, izitezi zamabhuloho, nemishayo ethwala imithwalo. Uma ingaphansi kwemiphumela ephindaphindiwe yokugingqika kwemoto, isisindo esifile kanye nemvelo yemvelo (njengokushintsha komoya nezinga lokushisa), i-rebar inikeza ukumelana okwanele nokucindezelwa kwamabhuloho, iqinisekisa ukuzinza nempilo yesevisi yamabhuloho.

• Ezokuthutha ngomgwaqo nojantshi: Ekuqinisweni komgwaqo wemigwaqo emikhulu kanye nesakhiwo esisekela ujantshi wesitimela esihamba ngaphansi komhlaba, i-rebar ngokuvamile isetshenziselwa ukwenza izingxenye zikakhonkolo eziqinisiwe ukuze kuthuthukiswe umthamo wokuthwala wemigwaqo namathrekhi ukuze ubhekane nokugcwala kwethrafikhi njalo.

• Amaphrojekthi okonga amanzi: Izinsiza zokonga amanzi njengamadamu amadamu, imigudu yokuphambukisa amanzi, kanye nama-culverts angaphansi komthelela wesikhathi eside kanye nomfutho wamanzi. I-skeleton yensimbi eyenziwe nge-rebar ingathuthukisa kakhulu ukumelana nokuqhekeka nokuqina kwezakhiwo zikakhonkolo, iqinisekise ukusebenza okuphephile kwamaphrojekthi okonga amanzi.

Imboni nobunjiniyela obukhethekile

I-Rebar nayo idlala indima ebalulekile ezitshalweni zezimboni, izindawo zokugcina izimpahla, kanye nezisekelo zemishini emikhulu. Isibonelo, isisekelo semishini yemishini esindayo sidinga ukumelana nesisindo esikhulu semishini kanye nokudlidliza ngesikhathi sokusebenza. Inhlanganisela ye-rebar kanye nokhonkolo inganikeza amandla aqinile wesakhiwo ukugwema ukuhlala kwesisekelo noma ukulimala. Ukwengeza, kwamanye amaphrojekthi akhethekile anjengezimboni zamandla enuzi kanye namatheminali echweba, i-rebar idinga ukuhlangabezana namandla aphezulu kanye nezidingo zokumelana nokugqwala ukuze ivumelane nezinselele zezindawo ezikhethekile.

Ngamafuphi, i-rebar, enezakhiwo zayo ezinhle kakhulu zemishini kanye nokusebenzisana okuhle nokhonkolo, isiphenduke "amathambo" okuqinisekisa ukuphepha kwesakhiwo kumaphrojekthi wokwakha wesimanje, ukusekela zonke izinhlobo zezakhiwo kusuka emidwebo yokuklama kuya eqinisweni.
