Ngokutsho kweengcali, intsimbi ibisoloko iyinto ebalulekileyo kwiprojekthi zokwakha kangangeminyaka emininzi, inika amandla abalulekileyo kunye nokuqina. Nangona kunjalo, njengoko iindleko zentsimbi ziqhubeka zinyuka kwaye amaxhala malunga nokukhutshwa kwekhabhoni enyuka, kukho imfuneko ekhulayo yezisombululo ezizezinye.
I-Basalt rebaryindlela ethembisayo enokusombulula zombini ezi ngxaki. Ngenxa yeempawu zayo ezintle kunye nobuhlobo bayo nokusingqongileyo, inokubizwa ngokuba yindlela efanelekileyo endaweni yentsimbi eqhelekileyo. Ivela kwilitye lentaba-mlilo, iibha zentsimbi yebasalt zinamandla okutyhafa amangalisayo, nto leyo eyenza ukuba zifaneleke ukusetyenziswa kwiindawo ezahlukeneyo zokwakha.
I-Basalt rebar yindlela eqinisekisiweyo yokutshintsha intsimbi yendabuko okanye ukuqinisa i-fiberglass kwikhonkrithi kwaye ikhula ngamandla njengobuchwepheshe obuvelayo e-UK. Ukusetyenziswa kwesi sisombululo sitsha kwiiprojekthi eziphambili ezifana ne-High Speed 2 (HS2) kunye nomgaqo omkhulu we-M42 kuya kugqama ngakumbi kwiiprojekthi zokwakha njengoko imizamo yokususa iicarbonization iqhubeka.
– Inkqubo yemveliso ibandakanya ukuqokelelai-basalt yentaba-mlilo, ukuyityumza ibe ziingceba ezincinci uze uyibambe kumaqondo obushushu afikelela kwi-1400°C. Iisilicates ezikwibasalt ziyiguqula ibe lulwelo olunokolulwa ngumxhuzulane ngeepleyiti ezikhethekileyo, zenze imigca emide enokufikelela kumawaka eemitha ubude. Ezi ntambo emva koko zibotshelelwa kwiispools kwaye zilungiselelwe ukwenza uqiniselo.
I-Pultrusion isetyenziselwa ukuguqula ucingo lwe-basalt lube ziintonga zentsimbi. Le nkqubo ibandakanya ukutsala imisonto ize iyifake kwi-epoxy resin engamanzi. I-resin, eyi-polymer, ifudunyezwa ibe yimeko engamanzi ize emva koko imisonto intywiliswe kuyo. Lonke ulwakhiwo luqina ngokukhawuleza, lujike lube yinduku egqityiweyo kwimizuzu embalwa.
