geonet drain
Fa'amatalaga o oloa
Fa'amatalaga o oloa:
O le mafiafia o Mesh o le 5mm-8mm, o le lautele o le 2-4m, ma le umi e tusa ai ma manaoga o tagata faatau.
Mea Fa'apitoa:
1. Malosi o alavai (e tutusa ma le 1m mafiafia alavai iliili).
2. Malosi maualuga tensile.
3. Fa'aitiitia le avanoa o geotextiles o lo'o fa'apipi'i i totonu ole mesh ma fa'atumauina alavai mautu mo se taimi umi.
4. Tumau umi taimi mamafa mamafa mamafa (e mafai ona tatalia se mamafa compressive e uiga i 3000Ka).
5. Corrosion teteʻe, acid ma alkali tetee, ma le ola auaunaga umi.
6. E faigofie le fausiaina, faʻapuʻupuʻu le taimi o le fausiaina, ma faʻaititia le tau.
Fa'atinoga Fa'atusa
E masani ona faʻaaogaina i nofoaafi, alatele, tunnels, inisinia faʻapitonuʻu, faatanoa, puipuiga malu ma isi galuega alavai ma se aafiaga ofoofogia.
