Imibuzo ebuzwa rhoqo

Q1: Yintoni umbhobho wokufaka iipayipi ezinkulu ngobukhulu?

Iipayipi ezinkulu ezinobubanzi obukhulu zizakhiwo ezisilinda ezisetyenziselwa ukuxhasa imithwalo enzima kwiiprojekthi zokwakha. Ububanzi bazo obukhulayo bunika amandla amakhulu okuthwala umthwalo kwaye zilungele iziseko ezinzulu kwiimeko zomhlaba ezinzima.

Q2: Kutheni ukhetha iipali zemibhobho yentsimbi edibeneyo ejikelezayo?

Iipayipu zentsimbi ezidityanisiweyo ezijikelezayo zaziwa ngamandla azo aphezulu kunye nokuqina kwazo. Inkqubo yokudityanisa ejikelezayo iqinisekisa umthungo oqhubekayo, ophucula ukuqina kwesakhiwo sepayipu. Le ndlela ikwavumela ukuveliswa kweepayipu zentsimbi ezinkulu ukuze kuhlangatyezwane neemfuno ezikhulayo zokwakha zanamhlanje.

Umbuzo 3: Zenziwa phi ezi mbhobho?

Iipayipi zethu zokufaka iipali ezinkulu ezikumgangatho ophezulu zenziwe eCangzhou, kwiPhondo laseHebei. Umzi-mveliso wethu wasungulwa ngo-1993 kwaye ugubungela indawo yeemitha zesikwere ezingama-350,000 kunye neeasethi zizonke ze-RMB ezingama-680 ezigidi. Sinabasebenzi abazinikeleyo abangama-680 abazinikele ekuveliseni izisombululo zokufaka iipali ezikumgangatho ophezulu ezihlangabezana neemfuno ezingqongqo zoshishino lokwakha.
