Abantu abaninzi abakaze beve ngetekhnoloji yokulungisa imipu ye-trenchless kuba igama layo lide kakhulu kwaye lidibene, kodwa igama layo lamazwe ngamazwe liyamangalisa. U.S. Highway Strategic Research Programme iyibiza ngokuba yeyona ihlala ixesha elide. kunye neendlela ezifanelekileyo zokulungisa.
Inkqubo yoPhando lweSicwangciso esiPhezulu saseMelika? Inkqubo yoPhando ngoNdlela weQhinga lase-U.S yeyona projekthi inkulu yophando lohola wendlela ehlabathini ukuza kuthi ga ngoku. Emva kokuziqhelanisa ixesha elide, abaphandi bafumanisa ukuba iikhonsepthi zoyilo lwemveli kunye neendlela zovavanyo zahluke kakhulu kwimeko yokwenyani. Ezinye iingxaki ezivela ngexesha lomsebenzi kunzima ukuzichaza ngeengcamango zemveli. Kuyimfuneko kakhulu ukwenza uphando lwezenzululwazi nolucwangcisiweyo ukwenza uluhlu olutsha lwemithetho kunye nemigangatho yoyilo, ukulinga kunye nokugcinwa kolwakhiwo ukuhlangabezana neemfuno zokwakhiwa kohola wendlela.

Kutheni le nto iteknoloji yokulungisa imipu inegama elinamandla kangangokuba amasebe aziwayo eUnited States ayayincoma?
Itekhnoloji yokulungisa itekhnoloji yokwakhiwa kwe-trenchless gunnning isebenzisa i-high-concentration kunye ne-high-viscosity yamanzi-based polymer composite materials njengesixhobo sokubopha, kunye negrabile ehlanjwe enye njenge-aggregate. Imijelo ihlanjululwa ngomoya woxinzelelo oluphezulu kwaye ifafazwe ngezinto ezidibeneyo. Iinkqubo ezine zokwakha zokuxuba kunye nokutshiza ioli ye-adhesive layer, i-bonding material kunye ne-aggregate, kunye nezinto zokutshiza zokunyanga zihlanganiswe kumatshini omnye wokulungisa imipu. Lungisani ngokusisigxina iintanda, iintanda, iintanda, imingxuma kwiasphalt kunye nesamente kwindlela yokuhamba ngeenyawo.
Ayisiyiyo loo nto kuphela, itekhnoloji yokulungisa imipu engenamjelo inoluhlu olubanzi lwezicelo, ezibandakanya isantya esiphezulu, udidi lokuqala, udidi lwesibini, iindlela zedolophu nelokishi; itela, isamente, iindlela zegrabile kunye neminye imiphezulu yendlela; iindleko zokwakha ziphantsi kwaye zinokugcina i-50% yezinto eziphathekayo; isantya sokulungisa sikhawuleza, kwaye sinokuvulwa kwi-traffic ngokukhawuleza emva kokulungiswa ukunciphisa ixesha lokuhamba elivaliweyo; xa sele ilungisiwe, akukho mfuneko yokulungiswa kwakhona, kwaye ubomi benkonzo bude beminyaka emi-5-10.
Abanye abantu banokucinga ukuba lo mxholo ungentla ubaxiwe, kodwa ezi zakhiwo zibonwa yiNkqubo yoPhando lweSicwangciso esiliQili sase-US kwaye zibonwa yiyo njengeyona ndlela izinzileyo nesebenzayo yokulungisa. Ingabonwa ukuba inowayo "ubuchule bokwenyani". Ingaba ucinga ntoni?
