Palasitika mafolafola lalaga geotextile
Lalaga geotextile o se mea geosynthetic lalaga mai polypropylene ma polypropylene ethylene lipine e fai ma mea mata.E fa'aaogaina lautele i fa'ainisinia geotechnical e pei o le fa'asao vai, eletise eletise, uafu, auala tele ma le fausiaina o nofoaafi.
1. Malosi maualuga Ona o le faʻaogaina o le palasitika uaea mafolafola, e mafai ona faʻatumauina lava le malosi ma le faʻalauteleina i tulaga mago ma susu.
2. Tete'e a'afia E mafai ona tete'e le pala mo se taimi umi i le palapala ma le vai e eseese pH.
3. Suavai lelei E iai va i le va o uaea mafolafola, o lea e lelei ai le vai.
4. Lelei mea faʻamaʻi faʻamaʻi, leai se faʻaleagaina i microorganisms ma moths.
5. Faiga faigofie Ona o le mea e mama ma vaivai, e faigofie mo felauaiga, faʻapipiʻi ma fausiaina.
Folasaga o oloa
Fa'amatalaga o oloa:
Ole mamafa ole kalama e 90g/㎡～400g/㎡;o le lautele e 4~6mita.
Mea Fa'apitoa:
O le mamafa mama, malosi maualuga, laʻititi laʻititi, faʻamaoni lelei, ma le faʻaogaina faigofie;o loʻo i ai galuega o le faʻamalosia, vavaeeseina, alavai, faʻamamaina ma poloka.
Fa'atinoga Fa'atusa
1. Fa'ainisinia Fa'asao Suavai: taligalu, fa'ata'ita'i vaitafe, ma le vaituloto fa'ata'atiaga;Poloketi e puipuia ai le fatafata, galuega fa'afefe vai;fa'asao ma fa'agata fa'alavelave ma fa'amalosia galuega fa'atanoa;pa puipui ma tanu;galuega fa'atonutonu lologa.
2. Inisinia auala tetele: fa'avae vaivai togafitiga fa'amalosia;puipuiga malu;fa'alava fa'apipi'i fa'apipi'i;alavai;fusipa'u vavae lanu meamata.
3. Fa'ainisinia nofoaafi: poloketi fa'amalosia moega faavae;fa'amaufa'ailoga fa'afa'afafa;alavai e le susu ma alavai;alavai tauaso geotextile.
4. Inisinia Malaeva'alele: fa'amalosia fa'avae auala;fa'avae talieleele ma le fausaga o le auala laupapa;auala malaevaalele ma alavai.
5. Enisinia fale eletise: inisinia faavae ole fale eletise faaniukilia;fa'ainisinia afu dam o fale eletise vevela;inisinia fale eletise.
