Okwangoku, ilizwe lam liphumeza ukutshiswa kwenkunkuma yasekhaya, kwaye ukulahlwa kwenkunkuma yokuqala kuya kuncipha ngokuthe ngcembe. Kodwa isixeko ngasinye sidinga ubuncinci indawo yokulahla inkunkuma enye yokulahla okungxamisekileyo kunye nokutshiswa kothuthu. Kwelinye icala, ngoku kukho iindawo ezininzi zokulahla inkunkuma eqinileyo ethe yazaliswa kwaye kufuneka ivalwe. Ke ngoko, kwixa elizayo, i-geosynthetics iya kuba nethemba elikhulu kwintengiso ekuvalelekeni kokuvalwa kwenkunkuma eqinileyo kunye nokhuselo lwexeshana lwendawo yokulahla inkunkuma esebenza.
Oku kubizwa ngokuba yi-inshorensi yokuvala kuthetha ukuba xa inkunkuma eqinileyo igcwaliswa, kufuneka kwakhiwe ulwakhiwo oludityanisiweyo olugqumayo phezu komhlaba ukuze kuthintelwe ukungena kwamanzi emvula kunye nokuphuphuma kwerhasi yokulahla inkunkuma, kwaye izityalo zingatyalwa ukuze zibe luhlaza kwaye zibuyiselwe. Kukho iintlobo ezintathu eziphambili zemathiriyeli ye-geosynthetic esetyenziswa kwikhava yentsimi: i-polyethylene ephantsi yoxinaniso (LDPE) geomembrane, ingubo ye-bentonite engenamanzi kunye nenethi edibeneyo yokukhupha amanzi. Phakathi kwabo, i-LDPE geomembrane ine-ductility enhle, akulula ukuyikrazula, kwaye inokudlala indima enhle kwi-anti-seepage kunye ne-air-sealing. Iipropathi zomqobo ezichasene ne-seepage ze-bentonite zengubo engenamanzi nazo zilungile kakhulu. Xa kuthelekiswa ne-geomembrane, ayiyi kunqumla ngokupheleleyo umphunga wamanzi phantsi komgangatho wokugquma, ohambelana nokukhula kwezityalo.
Ukugutyungelwa okwethutyana kweendawo zokulahla inkunkuma eqinileyo ekwinkonzo kukugquma imiphezulu yenkunkuma evelileyo nge-geosynthetics kwiindawo ezingagalelwanga okwethutyana ukunciphisa ukungena kwamanzi emvula kunye nokuphuphuma kwerhasi yokulahla. Ukhuselo lwexeshana lukwaqhele ukusetyenziswa kwiiprojekthi zonyango lwendawo yongcoliseko ukunqanda iigesi eziyingozi eziguquguqukayo ukuba zingaphumi emoyeni. Kwiintsuku zangaphambili, iiseyile, iifilim, njl.njl. zazisetyenziswa ngokubanzi ukugqunywa okwethutyana, kodwa iingxaki ezinje nge-anti-seepage engalunganga kunye nesiphumo sokutywinwa komoya kunye nokukrazuka lula kwee-welds zaziqhele ukwenzeka. Okwangoku, iindawo zokulahla inkunkuma zineemfuno eziphezulu neziphezulu zokulahla inkunkuma evaliweyo. Ezinye iindawo zokulahla inkunkuma zisebenzisa i-1mm engqindilili ye-HDPE geomembrane kukhuselo lwexeshana. Isiphumo sokutywinwa phantsi singcono.
