Kushandiswa Kukuru

1. Nheyo dzeMadziro ePasi pevhu:Kuvakwa kwepasi pevhu kwezvivakwa zvirefu, mafekitori, matura, zvivakwa zvemabhizinesi nedzimba dzekugara. Nheyo dzemadura (marudzi ese ekuvaka zvivakwa).

2. Nheyo dzeBridge Pile:Nheyo dzakagadzirwa nemabhiriji emigwagwa mikuru, mabhiriji enjanji, uye nzira dzemumaguta. Nheyo dzakagadzirwa nemabhiriji erwizi, dhamu negungwa.

3. Kuvakwa kweChiteshi:Nheyo dzinotakura mutoro dzezviteshi zvechiteshi, nzvimbo dzekutakura ngarava nemapureti echiteshi. Mabasa ekutakura zvinhu zvinorema nemidziyo inorema.

4. Mapurojekiti ekugadzira magetsi emhepo neinjiniya yegungwa:Nheyo dzematurbine emhepo ari kunze kwenyika. Dhizaini yekutsigira mapuratifomu ari kunze kwenyika, mapaipi ari kunze kwenyika, mapaipi ari kunze kwenyika, madziro egungwa uye panguva imwe chete Mudzimba dzekugara Kuramba mafungu, kuramba mafungu, uye ngura yegungwa.

5. Mainjiniya Ekuvaka Akakura:Nheyo dzakasimba dzine mirwi yakafara yemabasa makuru einjiniya yezvivakwa (madhamu, zviteshi zvepasi pevhu, uye matunnel). Rutsigiro rwemichina yeindasitiri nemitoro yezvivakwa.

3) Inoongororwa nemasangano ane chiremera akadai seCCIC, SGS, BV, uye TUV, ine mapurasitiki akajairika anokodzera kufamba mugungwa

Kurongedza Uye Kutumira

1 Kurongedza:Matambiro esimbi ekubata zviri nyore. Mabhuroko emapuranga kana kuti dunnage anoiswa pakati pemaburi emiti kudzivirira kuchinja kwenhengo panguva yekutumira. Kugadzirisa pamusoro (sarudzo): Pendi nhema, mafuta ekudzivirira ngura, firimu repurasitiki. Makomba esimbi anogonawo kuputirwa mufirimu repurasitiki rekudzivirira kwenguva pfupi kudzivirira kukwenya pamusoro. Kurongedza kwakagadzirwa kunowanikwa.

2 Ruzivo rweKutumirwa:Hurefu Hwakajairika Huripo: 6m, 12m. Hurefu: hwakajairika uye hwakajairwa. Hunouya neSea Rail uye Mugwagwa Kushanda Kwazvo. Zvakakodzera kutakura zvinhu mugungwa, muchitima kana mumugwagwa, zvakare zvakasimba pakushandisa mumigwagwa. Nguva yekutumira zvinhu mazuva gumi nemashanu kusvika makumi matatu mushure mekugamuchira muripo, zvichienderana nehuwandu uye zvakatsanangurwa. Zvinoshanda kune dzimwe nyika, nemagwaro akazara (Test Certificate, Packing List, Bill of Lading).

3 Nzira dzekudzivirira:Usashandise zvirembe kana zvikorekedzo zvisina mapedhi kuti ubate zvakananga pamusoro pepombi izvo zvinogona kukonzera kuchinja kwepombi. Chengeta munzvimbo inotonhorera, yakaoma uye ine mhepo yakanaka. Kudzivirira ngura usati waisa. Mitoro yakakura uye yakakora inofanira kutevedzera mitemo yekutakura zvinhu yemuno.
