Ifomu yoMjelo

Inkcazo emfutshane:

Ifom yeTunnel luhlobo lwefom yohlobo oludibeneyo, oludibanisa ifom yodonga olufakwe kwindawo kunye nefom yomgangatho ofakwe kwindawo ngokusekelwe kulwakhiwo lwefom enkulu, ukuze ixhase ifom kube kanye, ibophe intsimbi kube kanye, kwaye igalele udonga kunye nefom kube yimo kube kanye ngaxeshanye. Ngenxa yesimo esongezelelweyo sale fom ifana netonela engunxande, ibizwa ngokuba yifom yetonela.

Iinkcukacha zeMveliso

I-tunnel formwork yinkqubo ye-formwork enokusetyenziswa ngexesha lomjikelo oqhelekileyo ukwenza iindonga kunye ne-formwork yenkqubo. Le nkqubo ivelisa izakhiwo ezisebenzayo ezithwala imithwalo ezisetyenziswa kakhulu. Indawo ye-tunnel formwork ithatha i-2.4-2.6 yeemitha, okwenza kube lula ukwahlulahlula nokwakha iindawo ezincinci.

Inkqubo yokwakhiwa kwemisele isetyenziswa ekuveliseni izakhiwo ezifana nezindlu, izindlu zentolongo, kunye neehostele zabafundi ezinesakhiwo esifana nesinye. Ngokuxhomekeke kubukhulu besakhiwo, inkqubo yokwakhiwa kwemisele inika umgangatho oqingqiweyo kwiintsuku ezi-2 okanye ngosuku olunye. Izakhiwo eziveliswe yinkqubo yokwakhiwa kwemisele zisebenza kakuhle, ziyakwazi ukumelana neenyikima, zinobunzima obuncinci bokuvelisa kwaye zineendleko eziphantsi zomsebenzi. Inkqubo yokwakhiwa kwemisele ikhethwa kakhulu kwizakhiwo zomkhosi.

Iimpawu

Isakhiwo
Ifomu ilungiselelwe ngokukodwa iprojekthi nganye. Indlela ephindaphindwayo yenkqubo kunye nokusetyenziswa kweefom ezenziwe kwangaphambili kunye neemathi/iikheji zokuqinisa kwenza kube lula yonke inkqubo yokwakha, nto leyo ebangela ukusebenza okuthe tye nokukhawulezayo. Iindlela ezisetyenzisiweyo sele ziqhelekile kushishino, kodwa ngokwakhiwa kweefom zetonela akukho kuxhomekeka kakhulu kubasebenzi abanezakhono.

Umgangatho
Umgangatho uyaphucuka nangona ulwakhiwo lukhawuleza. Ubuso obuchanekileyo, obufanayo bentsimbi yefomwork budala ukugqitywa okugudileyo, okusemgangathweni ophezulu okukwaziyo ukuhombisa ngokuthe ngqo kunye nokulungiswa okuncinci (kunokufuneka i-skim coat). Oku kunciphisa imfuneko yokulandela urhwebo, ngaloo ndlela kubonelela ngokonga iindleko ezongezelelweyo kunye nokukhawulezisa yonke inkqubo.

Uyilo
Iibhayi ezinkulu ezakhiwe ngendlela yetonela zibonelela ngokuguquguquka okumangalisayo kuyilo kunye noyilo lwesakhiwo kwaye zivumela inqanaba eliphezulu lenkululeko kwimbonakalo yokugqibela.

ukhuseleko
Uhlobo lweTunnel lunamaqonga okusebenza adibeneyo kunye neenkqubo zokukhusela umphetho. Ukongeza, indlela ephindaphindwayo neqikelelwayo yemisebenzi ebandakanyekayo ikhuthaza ukuqhelana nemisebenzi, kwaye, xa uqeqesho lugqityiwe, imveliso iyaphucuka njengoko ulwakhiwo luqhubeka. Imfuneko encinci yezixhobo kunye nezixhobo xa kushukunyiswa uhlobo lweTunnel inciphisa ngakumbi umngcipheko weengozi kwindawo.
