Ngokusho kochwepheshe, insimbi iye yaba yinto eyisisekelo emisebenzini yokwakha amashumi eminyaka, inikeza amandla abalulekile nokuhlala isikhathi eside. Kodwa-ke, njengoba izindleko zensimbi ziqhubeka nokukhuphuka nokukhathazeka mayelana nokukhishwa kwekhabhoni kwanda, kunesidingo esikhulayo sezinye izixazululo.
I-Basalt rebariyindlela ethembisayo engaxazulula zombili izinkinga. Ngenxa yezici zayo ezinhle kakhulu kanye nobungane bemvelo, ingabizwa ngempela ngenye indlela efanelekayo yensimbi evamile. Esuselwe etsheni lentaba-mlilo, imigoqo yensimbi ye-basalt inamandla ahlabayo ahlabayo, okuyenza ifanelekele ukusetshenziswa kuzinhlelo zokusebenza ezihlukahlukene zokwakha.
I-Basalt rebar iyindlela efakazelwe yensimbi yendabuko noma i-fiberglass yokuqinisa ukhonkolo futhi idlondlobala njengobuchwepheshe obusafufusa e-UK. Ukusetshenziswa kwalesi sixazululo kumaphrojekthi aphezulu njenge-High Speed 2 (HS2) kanye nomgwaqo onguthelawayeka uM42 kuya ngokuya kugqama kumaphrojekthi wokwakha njengoba imizamo yokususa i-carbonisation iqhubeka.
– Inqubo yokukhiqiza ibandakanya ukuqoqai-volcanic basalt, uyichoboze ibe yizicucu ezincane bese uyibamba emazingeni okushisa afinyelela ku-1400°C. Ama-silicates ku-basalt awenza abe uketshezi olunganwetshwa amandla adonsela phansi ngamapuleti akhethekile, enze imigqa emide engafinyelela izinkulungwane zamamitha ubude. Lezi zintambo zibe seziboshelwa phezu kwama-spools futhi zilungiselelwa ukwenza ukuqinisa.
I-pultrusion isetshenziselwa ukuguqula i-basalt wire ibe yizinduku zensimbi. Inqubo ihilela ukukhipha imicu bese uyicwilisa ku-liquid epoxy resin. I-resin, eyi-polymer, ishiselwa esimweni esiwuketshezi bese imicu icwiliswa kuyo. Isakhiwo sonke siqina ngokushesha, siphenduka induku eqediwe ngendaba yamaminithi.
