Ingxaki:
Impembelelo ye-concrete breakers kunye ne-jackhammers ayikhawulelwanga kwikhonkrithi eyonakeleyo. Ingonakalisa i-rebar kwaye ivelise i-vibration eyenza i-microfractures kwikhonkrithi yesandi. Andisathethi ke ngengxolo nothuli.
Isisombululo:
Phezulu-iijethi zamanzi zoxinzelelo(izixhobo ze-hydrodemolition) zihlasela i-fissures kwikhonkrithi ephosakeleyo, igcina ikhonkrithi yesandi kwaye iyishiye kunye nokuthungwa okugqwesileyo kokubambisana okutsha. Abayi konakalisa i-rebar, endaweni yoko basuse endalaikhonkrithi kunye nesikali, kunye nokuhlamba iikloridi ezifakiweyo. Iinkqubo zerobhothi zenza ukuba ukujelwa kwamanzi kube nemveliso ngakumbi.
Izinto eziluncedo:
• Amazinga okususwa ngokukhawuleza
• Ayisayi konakalisa ikhonkrithi yesandi okanye isithinteli somqolo
• Ingxolo ephantsi kunye namanqanaba othuli
• Ishiya indawo edityanisiweyo elungileyo yekonkrithi entsha
