Isicelo Esiyinhloko

1. Izisekelo Zodonga Olungaphansi:Izisekelo ezijulile zezakhiwo ezinde, amafektri, izindawo zokugcina impahla, izakhiwo zebhizinisi nezindawo zokuhlala. Izisekelo zenqwaba (ezifanele zonke izinhlobo zezakhiwo).

2. Izisekelo Zezinqwaba Zebhuloho:Izisekelo ezithwala imithwalo zamabhuloho omgwaqo omkhulu, amabhuloho esitimela, kanye nemigwaqo yasemadolobheni. Izisekelo zenqwaba zamabhuloho omfula, echibini, kanye nawawela ulwandle.

3. Ukwakhiwa Kwechweba:Izisekelo ezithwala imithwalo zezindawo zokubeka imithwalo, izindawo zokubeka imikhumbi, kanye namapulatifomu okubeka imithwalo. Imishini esindayo kanye nezindawo zokuphatha imithwalo yemithwalo yemikhumbi.

4. Amaphrojekthi Obunjiniyela Bomoya Olwandle kanye Nomoya Osebenza Ngaphandle:Izisekelo zama-turbine omoya asogwini lolwandle. Umklamo wokusekela amapulatifomu asogwini lolwandle, amapayipi asogwini lolwandle, izindonga zasolwandle, njll. Ukumelana namaza, ukumelana namaza, kanye nokumelana nokugqwala kolwandle.

5. Ubunjiniyela Bokwakha Obukhulu:Izisekelo ezijulile ezinezinqwaba ezinkulu zamaphrojekthi amakhulu obunjiniyela bezakhiwo (njengamadamu, iziteshi zangaphansi komhlaba, kanye nemigudu). Ukusekelwa kwemishini yezimboni kanye nemithwalo yezakhiwo.

3) Kuhlolwa izinhlangano ezigunyaziwe njenge-CCIC, i-SGS, i-BV, ne-TUV, kanye nokupakishwa okujwayelekile okufanele ulwandle

Ukupakisha Nokulethwa

1 Ukupakisha:Ibhande lensimbi ukuze kube lula ukuphatha. Amabhulokhi okhuni noma i-dunnage kubekwa phakathi kwezinqwaba ukuze kugwenywe ukushintsha kwezitho ngesikhathi sokuthuthwa. Ukwelashwa kwendawo (ongakukhetha): Ukupenda okumnyama, uwoyela wokuvimbela ukugqwala, ifilimu yepulasitiki. Izinqwaba ze-galvanized ezicwiliswa ngokushisa zingase zimbozwe ifilimu yokuvikela yesikhashana ukuze kugwenywe ukuklwebheka ebusweni. Kunganikezwa ukupakishwa okwenziwe ngokwezifiso.

2 Ukulethwa:Ubude besitoko obujwayelekile: 6m, 12m. Itholakala ngobude obujwayelekile. Iza ne-Sea Rail kanye ne-Road Esebenzayo. Ifanelekela ezokuthutha olwandle, isitimela noma umgwaqo. Isikhathi sokulethwa sivame ukuba yizinsuku eziyi-15-30 ngemuva kokuthola inkokhelo, kuye ngobuningi kanye nemininingwane. Ifanelekela ukuthunyelwa kwamanye amazwe emhlabeni jikelele, kanye nedokhumenti ephelele (isitifiketi sokuhlola, uhlu lokupakisha, i-bill of lading).

3 Izinyathelo Zokuqapha Zokusingatha:Ungasebenzisi izihlilingi noma izingwegwe ezingenamaphedi ukuze zisebenze ngqo ebusweni bepayipi ukuze ugweme ukuthi ipayipi lingaguquki. Gcina endaweni epholile, eyomile futhi enomoya omuhle, gwema ukugqwala ngaphambi kokufaka. Ukuthunyelwa okukhulu kakhulu nokwesisindo esikhulu sicela uhambisane nemithetho yokuthumela yendawo.
