Isicelo Esiphambili

1. Iziseko zoDonga oluseMgangathweni:Ukwakhiwa komhlaba phantsi kwezakhiwo eziphakamileyo, iifektri, iindawo zokugcina impahla, izakhiwo zorhwebo nezindlu zokuhlala. Iziseko zeenqwaba (zonke iintlobo zokwakha izakhiwo).

2. Iziseko zeBridge Pile:Iziseko ezithwele iibhulorho zeendlela ezinkulu, iibhulorho zikaloliwe, kunye nee-viaducts zasezidolophini. Iziseko ezithwele iibhulorho zomlambo, ichibi kunye neebhulorho zolwandle.

3. Ukwakhiwa kweZibuko:Isiseko sokuthwala imithwalo seetheminali zezibuko, iiyadi zeenqanawa kunye neepleyiti zezibuko. Izixhobo ezinzima kunye neenkonzo zokuhanjiswa kwemithwalo yezibuko.

4. Iiprojekthi zoBunjineli boMbane woMoya noLwandle oluPhesheya:Iziseko zeeturbine zomoya ezikude nolwandle. Uyilo lwenkxaso yamaqonga akude nolwandle, iipayipi ezikude nolwandle, iipayipi ezikude nolwandle, iindonga zolwandle kwaye okwangoku Kwizindlu zokuhlala Ukumelana namaza, ukumelana namaza, kunye nokugqwala kolwandle.

5. Ubunjineli Bokwakha Obukhulu:Iziseko ezinzima ezineenqwaba ezibanzi zomsebenzi wobunjineli bokwakha obukhulu (amadama, izitishi zesitimela esingaphantsi komhlaba, kunye neetonela). Inkxaso yoomatshini bemizi-mveliso kunye nemithwalo yezakhiwo.

Ukupakisha kunye nokuHanjiswa

Ukupakisha oku-1:Iintambo zentsimbi ukuze kube lula ukuziphatha Iibhloko zomthi okanye i-dunnage zifakwa phakathi kweenqwaba ukuthintela ukutshintsha kwezitho ngelixa kusenziwa inkqubo yokuthunyelwa. Unyango lomphezulu (ukhetho): Ukupenda okumnyama, ioyile yokuthintela umhlwa, ifilimu yeplastiki. Iinqwaba ze-galvanized zingasongelwa kwifilimu yeplastiki yokukhusela yexeshana ukuthintela ukukrwela umphezulu. Kukho upakisho olwenziwe ngokwezifiso.

2 Ulwazi lokuHanjiswa:Ubude obuqhelekileyo obukhoyo: 6m, 12m. Ubude: obuqhelekileyo nobuqhelekileyo. Ziza noLoliwe lwaseLwandle kunye nokusetyenziswa kwendlela. Zilungele ukuthutha ngolwandle, ngololiwe okanye ngemoto, zikwanamandla ngokwaneleyo xa zisetyenziswa endleleni. Ixesha lokuhambisa liphakathi kweentsuku ezili-15-30 emva kokufumana intlawulo, kuxhomekeke kubungakanani kunye neenkcukacha. Zisebenza ekuthumeleni impahla kwamanye amazwe kwihlabathi liphela, kunye noxwebhu olupheleleyo (Isatifikethi sovavanyo, Uluhlu lokupakisha, iBill of Lading).

3 Amanyathelo okuphatha:Musa ukusebenzisa izilingi okanye iihoko ezingenazo iipadi ukuze udibane ngqo nomphezulu wombhobho nto leyo enokubangela ukuguguleka kombhobho. Gcina kwindawo epholileyo, eyomileyo nengena umoya kakuhle. Ukuze uphephe ukugqwala ngaphambi kokufakwa. Imithwalo emikhulu nenzima kakhulu kufuneka ilandele imigaqo yokuthunyelwa kwempahla yasekuhlaleni.
