Kutshanje, iivalvu ezimbini ezithambileyo zesango lokutywina ezinobukhulu be-DN700 zithunyelwe ngempumelelo zisuka kumzi-mveliso wethu wevalvu. Njengomzi-mveliso wevalvu waseTshayina, ukuthunyelwa ngempumelelo kwe-Jinbin yobungakanani obukhulu bevalve yesango lokutywina kwakhona kubonisa isakhono esibalaseleyo somzi-mveliso ekwenzeni iivalvu ngokwezifiso.

Kutheni ukhetha ivalve yesango ethambileyo enobubanzi obukhulu?

Okokuqala,ivalve yesango elithambileyozineenzuzo zokusebenza kokutywina kunye nokusebenza ngokulula, ngelixa uyilo olukhulu lwedayamitha luhlangabezana neemfuno ezithile zobunjineli kulawulo lokuhamba okuphezulu. Kwiinkqubo zonikezelo lwamanzi ezidolophini kunye neenkqubo zokuhambisa amanzi, iivalvu zesango ezitywiniweyo ezinobubanzi obukhulu ezinobubanzi obuthambileyo zinokulawula ngokufanelekileyo ukuhamba kwamanzi, ziqinisekise unikezelo lwamanzi oluzinzileyo kunye nokuphuma kwamanzi agudileyo. Kwizityalo zokucocwa kwamanzi amdaka, inokulawula ngokuthembekileyo ukuhamba kwamanzi amdaka kunye nokubonelela ngenkxaso eqinileyo kwinkqubo yokucocwa kogutyulo. Kwiiprojekthi ezinkulu zemizi-mveliso ezifana neekhemikhali kunye namashishini ombane, okuivalve yesango eneflangedinokudlala indima ebalulekileyo ekuphumezeni ulawulo oluchanekileyo lwemithombo yeendaba ezahlukeneyo.

Isitywina esithambileyo se-DN700 sobubanzi obukhuluixabiso levalve yesangoithunyelwe ngeli xesha kuye kwavavanywa umgangatho ongqongqo kunye nokuveliswa okuchanekileyo ngumzi-mveliso, ukuqinisekisa ukuthembeka kunye nokuzinza kwayo ngexesha lokusetyenziswa.

Umzi-mveliso wethu ubusoloko uzibophelele ekuboneleleni abathengi ngeenkonzo zevalvu ezikumgangatho ophezulu. Ukusuka kuyilo ukuya kwimveliso, inyathelo ngalinye lilawulwa ngokungqongqo ukuhlangabezana neemfuno zobuqu zabathengi abahlukeneyo. Ngezixhobo zokuvelisa eziphucukileyo, iqela lobuchwephesha lobuchwephesha, kunye nenkqubo yolawulo engqongqo yomgangatho, siye safumana ukuqondwa kubathengi abaninzi.

Ukuthunyelwa kwevalve yesango etywiniweyo enobubanzi obukhulu obuthambileyo ngeli xesha ayiyompumelelo ebalulekileyo kuphela kumzi-mveliso, kodwa ikwabonelela ngenkxaso eyomeleleyo kuphuhliso lwamashishini anxulumeneyo. Ndiyakholelwa ukuba kwixesha elizayo, njengomvelisi wevalvu yesango laseTshayina, i-Jinbin iya kuqhubeka iqhutywa yintsha kunye nomgangatho, ukubonelela abathengi ngeemveliso zevalvu ezikumgangatho ophezulu kunye negalelo elikhulu kuphuhliso lweshishini lokuvelisa izivalo.
