Ngokusho kochwepheshe, insimbi ibilokhu iyimpahla ebalulekile kumaphrojekthi okwakha amashumi eminyaka, inikeza amandla nokuqina okubalulekile. Kodwa-ke, njengoba izindleko zensimbi ziqhubeka nokwenyuka nokukhathazeka mayelana nokukhishwa kwekhabhoni kuyanda, kunesidingo esikhulayo sezinye izixazululo.
I-Basalt rebariyindlela ehlukile ethembisayo engaxazulula zombili lezi zinkinga. Ngenxa yezici zayo ezinhle kakhulu kanye nobungane bayo nemvelo, ingabizwa ngempela ngokuthi iyindlela ehlukile efanelekile kunensimbi evamile. Ithathwe edwaleni lentaba-mlilo, imigoqo yensimbi ye-basalt inamandla okubamba amangalisayo, okwenza ifaneleke ukusetshenziswa ezinhlotsheni ezahlukene zokwakha.
I-Basalt rebar iyindlela ehlukile efakazelwe esikhundleni sensimbi yendabuko noma ukuqinisa i-fiberglass kokhonkolo futhi iyanda njengobuchwepheshe obusafufusa e-UK. Ukusetshenziswa kwalesi sixazululo esisha kumaphrojekthi aphezulu njenge-High Speed 2 (HS2) kanye nomgwaqo omkhulu i-M42 kuya ngokuya kugqama kumaphrojekthi okwakha njengoba imizamo yokususa i-carbonization iqhubeka.
- Inqubo yokukhiqiza ihilela ukuqoqai-basalt yentaba-mlilo, ukuyichoboza ibe yizicucu ezincane bese uyibamba emazingeni okushisa afinyelela ku-1400°C. Ama-silicates ase-basalt ayiguqula ibe uketshezi olungalulwa ngamandla adonsela phansi ngamapuleti akhethekile, adale imigqa emide engafinyelela izinkulungwane zamamitha ubude. Lezi zintambo zibe seziboshelwa ezitsheni bese zilungiselelwa ukwakha ukuqina.
I-Pultrusion isetshenziselwa ukuguqula ucingo lwe-basalt lube yizinduku zensimbi. Le nqubo ihilela ukudonsa imicu bese uyicwilisa ku-epoxy resin ewuketshezi. I-resin, okuyi-polymer, ishiswa ibe yisimo soketshezi bese imicu ifakwa kuyo. Isakhiwo sonke siyaqina ngokushesha, siphenduke induku eqediwe ngemizuzu embalwa.
