Amathuba okusetyenziswa kunye nemingeni yefiber yeglasi kunye nezixhobo ezidibeneyo kwintsimi yeziseko

Namhlanje ndifuna ukwabelana nawe ngenqaku:

Kwiminyaka elishumi eyadlulayo, iingxoxo malungaiziseko zophuhlisoyayimalunga nokuba yimalini eyongezelelweyo efunekayo ukuyilungisa. Kodwa namhlanje kukho ugxininiso olukhulayo lokuzinza kunye nokuqina kwiiprojekthi ezibandakanya ukwakhiwa okanye ukulungiswa kweendlela zelizwe, amabhuloho, amachweba, iigridi zamandla, kunye nokunye.

Ishishini elihlanganisiweyo linokubonelela ngezisombululo ezizinzileyo ezifunwa ngamazwe ase-US. Ngokunyuka kwenkxaso-mali, njengoko kucetyiwe kwibhili yeziseko ezingundoqo ezisisi-1.2 seetriliyoni zeerandi, ii-arhente zombuso wase-US ziya kuba nenkxaso-mali eninzi kunye namathuba okulinga ubugcisa obutsha kunye nobuchule bokwakha.

U-Greg Nadeau, uSihlalo kunye ne-CEO ye-Infrastructure Ventures, uthe, “Kukho imizekelo emininzi kulo lonke elase-United States apho ukusetyenziswa kwezinto ezintsha eziyintlanganisela kuye kwabonakala kusebenza, nokuba ziibhulorho okanye izakhiwo eziqinisiweyo. Impembelelo enkulu kuMthetho weziSeko ezinguNdoqo zeBridge phezu kolwabiwo-mali oluqhelekileyo Utyalo-mali alunikeli ithuba lokuba amazwe asebenzise ezi mali ukwandisa ukusetyenziswa nokuqonda kwezi mathiriyeli zingenye. Ayizolingo, zibonakalisiwe ziyasebenza. ”

Izinto ezihlanganisiweyozisetyenziselwe ukwakha iibhulorho ezikwaziyo ukumelana nefuthe. Iibhulorho eziselunxwemeni lwase-US nakumantla amazwe asebenzisa ityuwa yendlela ngexesha lasebusika zibolile ngenxa yokubola kwentsimbi kwikhonkrithi eyomeleziweyo kunye nezakhiwo zekhonkrithi ezigxininisiweyo. Ukusebenzisa izinto ezingadlekiyo njengeembambo eziyintlanganisela kunokunciphisa imali ekufuneka iSebe Lezothutho lase-US (DOTs) liyichithe ekulungiseni nasekulungiseni ibhulorho.

UNadeau wathi: “Ngokuqhelekileyo, iibhulorho eziqhelekileyo eziphila iminyaka engama-75 zifanele zinyangwe ngokunzulu kwithuba leminyaka engama-40 okanye engama-50. Ukusebenzisa izinto ezingonakalisiyo ngokusekelwe kukhetho lwakho lwezinto eziphathekayo kunokwandisa ubomi benkonzo kunye nokunciphisa imijikelezo yobomi bexesha elide. ixabiso.”

Kukho nezinye iindleko ezongayo ngokunjalo. Ukuba besinesixhobo esingenakonakala, indlela eyenziwe ngayo ikhonkile ibinokwahluka. Ngokomzekelo, bekungayi kufuneka sisebenzise i-corrosion inhibitors, exabisa malunga ne-50 yeedola kwi-cubic yadi nganye, "utshilo uProfesa weYunivesithi yaseMiami kunye neSebe lezoBunjineli boBugcisa kunye noBunjineli u-Antonio Nanni.

Iibhulorho ezakhiwe ngezinto ezidibeneyo zinokuyilwa kunye nezakhiwo zenkxaso ezilungelelanisiweyo. UKen Sweeney, uMongameli kunye neNjineli eyiNtloko ye-Advanced Infrastructure Technologies (AIT), uthe: "Ukuba usebenzisa ikhonkrithi, ubuya kuchitha imali eninzi kunye nezixhobo zokwakha ibhulorho ukuxhasa ubunzima bayo, kungekhona umsebenzi wayo, oko kukuthi ukuthwala i-traffic. Ukuba unokunciphisa ubunzima bayo kwaye ube nomlinganiselo ophakamileyo wobunzima bobunzima, oko kuya kuba yinzuzo enkulu: kuya kuba kubiza kakhulu ukwakha. "

Ngenxa yokuba imivalo edibeneyo ilula kakhulu kunentsimbi, iilori ezimbalwa ziyafuneka ukuthutha imivalo edibeneyo (okanye iinqununu zebhulorho ezenziwe kwiibha ezidibeneyo) ukuya kwindawo yomsebenzi. Oku kunciphisa ukukhutshwa kwecarbon dioxide. Iikontraka zinokusebenzisa iikhreyini ezincinci, ezinexabiso eliphantsi ukuphakamisa amacandelo ebhulorho adibeneyo endaweni, kwaye kulula kwaye kukhuselekile kubasebenzi bokwakha ukuba bawathwale.
