Geotechnical mat maka mgbochi ọwa seepage na igbapu mmiri
Okwu mmalite:
Geo textile mat bụ ụdị ihe ọhụrụ geo sịntetik emere nke agwakọtara na ntupu nke filament na-adịghị mma.Ọ nwere nguzogide nrụgide dị elu, nnukwu njupụta nke oghere ma nwee nchịkọta mmiri na-agba gburugburu na ọrụ nkwụsịtụ kwụ ọtọ.Ihe owuwu a bụ isi akụkụ geo akpụkpọ ahụ nwere akụkụ atọ nwere akwa geo textile na-enweghị akpa n'akụkụ abụọ.Akụkụ geo mesh core dị akụkụ atọ na-agbapụta mmiri dị n'ime ala ngwa ngwa ma nwee usoro nlekọta pore nke ya, nke na-egbochi mmiri capillary n'okpuru nnukwu ibu.Ọ na-emekwa dị ka ihe mgbochi mkwado.
Njirimara ngwaahịa:
1. Nguzogide nrụgide dị elu, oghere oghere dị elu, na nchịkọta mmiri na-agba gburugburu na ọrụ nkwụsịtụ kwụ ọtọ.
2. Mgbe geotextile ute na- compounded na ndị na-abụghị kpara geotextile, ọ nwere ike na-anakọta mmiri ozuzo penetrating site na ala cover oyi akwa ma ọ bụ nsị awụpụ si yad n'onwe ya n'okpuru lie mechiri emechi cover oyi akwa, na-eji ya pụrụ iche drainage ọrụ na-ipu site na ala. geotextile mat sanwichi oyi akwa n'usoro dị n'usoro dị ka injinia chọrọ, na-enweghị imepụta silting.Ya mere, ọ nwere ike ịzenarị nsogbu sliding nwere ike ime n'ihi njupụta nke mmiri na-ekpuchi oyi akwa.
3. Geomat mat nwere ike ọ bụghị naanị igbapu mmiri, ma na-ahapụkwa methane gas na-emepụta site gbaa ụka na ala (karịsịa n'efu efu), nke kwesịrị ekwesị karịsịa maka ngwa na landfill.
4. geotechnical mat na HDPE jikọtara ngwa, n'otu oge ahụ nwere ike ịrụ ọrụ dị mma n'ichebe akpụkpọ anụ HDPE site na nsị.
