ERW Uamea Paipa mo le fa'atauina o taulaga
O paipa u'amea su'i sa'o mo le viliina i le taulaga, o paipa u'amea fa'apitoa ia e fa'aaogaina i galuega fa'ameamea i vaitafe i le taulaga, uafu, alavai ma isi ogasami. E masani ona fa'aaogaina e felauaiga ai le palapala, palapala ma isi otaota fefiloi.
O paipa u'amea su'i sa'o mo le viliina i le taulaga, o paipa u'amea fa'apitoa ia e fa'aaogaina i galuega fa'ameamea i vaitafe i le taulaga, uafu, alavai ma isi ogasami. E masani ona fa'aaogaina e felauaiga ai le palapala, palapala ma isi otaota fefiloi.
O nisi nei o fa'amatalaga autu e uiga i paipa u'amea su'i sa'o mo le su'eina o le taulaga:
Fa'agasologa o le gaosiga: O paipa u'amea sa'o mo le fa'ameamea i le taulaga e masani lava ona gaosia i le fa'aogaina o le fa'aogaina o le arc uelo fa'atekonolosi, lea e mafai ona fa'amautinoaina le tutusa ma le mamafa o le uelo.
Fa'aoga fanua: Fa'aaoga lautele i le toliina o matafaga, vaitafe, ma alavai, galuega tau puipuiga o le si'osi'omaga i taulaga, ma le fausiaina ma le fa'atumuina o alavai paipa eseese.
Fa'amatalaga fa'atekinisi: O paipa u'amea sa'o e iai le malosi ma le palasitika, lapoa paipa lapoa, puipui paipa mafiafia, fa'atosina maualuga, fa'amaulalo le vevela, ma le fa'a'ele'ele. E fetaui lelei mo le felauaiga o palapala o lo'o i ai ni mea'ai malo i galuega eli.
Meafaigaluega fa'afetaui: O le su'iina o paipa u'amea sa'o e masani ona fa'aoga i masini fa'ainisinia e pei o dredgers. E lua ituaiga o dredgers: masini ma hydraulic. Faatasi ai ma ia mea, e faʻafefeteina e le hydraulic dredgers le palapala i le vai maualuga pe faʻaaoga le reamers ma ulu ulu e tipi ai palapala. , ona fa'aaoga lea o se pamu palapala e su'e ai le palapala ile paipa u'amea.
Tulaga Fa'atonu: O le gaosiga o paipa u'amea sa'o e tatau ona fa'amalieina tulaga fa'ale-atunu'u talafeagai, e pei o le GB / T 13793-2016 "Papa u'amea fa'afefe eletise eletise".
Manaoga Maketi: Faatasi ai ma le faatelevaveina o le taulaga ma le faaleleia atili o manaoga o le puipuiga o le siosiomaga, o le manaoga mo paipa u'amea sa'o i totonu o galuega eli i taulaga o loo faaauau pea ona tupu.
Tamaoaiga: O le su'iina o paipa u'amea sa'o o lo'o fa'aaogaina lautele i galuega fa'ameamea i le taulaga ona o le tau taugofie.
Tulaga mana'omia: O paipa u'amea u'amea e mana'omia ona fa'amalieina tulaga fa'apitoa, e aofia ai mea fa'ainisinia o le paipa, sa'o sa'o ma lelei lelei.
I se aotelega, o paipa u'amea su'i sa'o mo le su'iina i le taulaga e iai sona sao taua i galuega eli i le taulaga ona o le lelei atoatoa o le faatinoga ma le tamaoaiga.
