Abantu abaningi abakaze bezwe ngobuchwepheshe bokulungisa izibhamu ezingenazintambo ezingenantambo ngenxa yokuthi igama labo lide kakhulu futhi lihlangene ngandlela thile, kodwa isithunzi salo samazwe ngamazwe siyamangalisa. I-U.S. Highway Strategic Research Programme ilubiza ngokuthi luhlala isikhathi eside kakhulu. kanye nezindlela zokulungisa ezisebenzayo.
Uhlelo lwe-American Highway Strategic Research Program? I-U.S. Strategic Highway Research Programme iphrojekthi enkulu kunazo zonke yocwaningo lomgwaqo omkhulu emhlabeni kuze kube manje. Ngemva kokuzijwayeza isikhathi eside, abacwaningi bathola ukuthi imiqondo yendabuko yokuklama nezindlela zokuhlola zihluke kakhulu esimweni sangempela. Ezinye izinkinga eziphakama ngesikhathi somsebenzi kunzima ukuzichaza ngemibono yendabuko. Kudingeka kakhulu ukwenza ucwaningo lwesayensi noluhlelekile ukuze kwakhiwe isethi entsha yemithetho nezindinganiso zokuklama, ukuhlola nokunakekelwa kokwakhiwa ukuze kuhlangatshezwane nezidingo zokwakhiwa komgwaqo omkhulu.

Kungani ubuchwepheshe bokukhanda izibhamu bunedumela eliqine kangangokuthi iminyango eyaziwayo yase-United States igcwele indumiso ngabo?
Ubuchwepheshe bokwakha isibhamu sokukhanda i-trenchless busebenzisa izinto ezihlanganisiwe ze-polymer ezigxile kakhulu kanye ne-viscosity yamanzi njengezinto zokubopha, futhi kugezwe igravel enohlamvu olulodwa njengeqoqo. Imisele ihlanzwa ngomoya womfutho ophezulu futhi ifafazwe ngezinto zokubopha. Izinqubo ezine zokwakha zokuxuba nokufafaza uwoyela wengqimba enamathelayo, impahla yokubopha kanye neqoqo, kanye nezinto zokuphulukisa zokufafaza zihlanganiswe emshinini owodwa wokulungisa izibhamu. Lungisa unomphela imifantu, imifantu, izindawo ezingaphansi nemigodi emigwaqweni yetiyela nekasimende.
Akugcinanga lapho, ubuchwepheshe bokukhanda izibhamu ezingenazintambo bunezinhlobonhlobo zezinhlelo zokusebenza, ezihlanganisa imigwaqo enesivinini esikhulu, esezingeni lokuqala, eyesigaba sesibili, imigwaqo yezifunda kanye nelokishi; itiyela, usimende, imigwaqo ewubhuqu nezinye imigwaqo; izindleko zokwakha ziphansi futhi zingonga izinto ezingama-50%; isivinini sokulungisa siyashesha, futhi singavulelwa ithrafikhi ngokushesha ngemva kokulungiswa ukunciphisa isikhathi sethrafikhi esivaliwe; uma usulungisiwe, asikho isidingo sokuphinda ulungise, futhi impilo yesevisi ifinyelela eminyakeni engu-5-10.
Abanye abantu bangase bacabange ukuthi okuqukethwe okungenhla kunehaba, kodwa lezi zakhiwo zibonwa yi-US Highway Strategic Research Programme futhi zibonwa yilo njengendlela ehlala isikhathi eside nesebenza kahle kakhulu yokulungisa. Kuyabonakala ukuthi “inekhono langempela” layo. UCABANGANI?
