Ukusetyenziswa kwe-geomembrane kwindawo yokulahla inkunkuma eqinileyo

I-geomembrane, njengesixhobo sobunjineli esisebenzayo nesithembekileyo, isetyenziswa kakhulu kwicandelo lenkunkuma eqinileyo. Iimpawu zayo ezizodwa zomzimba nezekhemikhali zenza ukuba ibe yinkxaso ebalulekileyo kwicandelo lonyango lwenkunkuma eqinileyo. Eli nqaku liza kuqhuba ingxoxo enzulu malunga nokusetyenziswa kwe-geomembrane kwindawo yokulahla inkunkuma eqinileyo ukusuka kwiimpawu ze-geomembrane, iimfuno zendawo yokulahla inkunkuma eqinileyo, imizekelo yesicelo, iziphumo zesicelo kunye neendlela zophuhliso zexesha elizayo ze-geomembrane kwindawo yokulahla inkunkuma eqinileyo.

1. Iimpawu ze-geomembrane

I-geomembrane, eyenziwe kakhulu nge-polymer ephezulu yeemolekyuli, ineempawu ezintle kakhulu zokungangeni manzi kunye neempawu zokungangenisi amanzi. Ubukhulu bayo buhlala buyi-0.2 mm Ukuya kwi-2.0 mm Phakathi, inokwenziwa ngokwezifiso ngokweemfuno ezithile zobunjineli. Ukongeza, i-geomembrane ikwanazo neekhemikhali ezilungileyo zokungangenisi manzi, ukumelana nokwaluphala, ukumelana nokuguguleka kunye nezinye iimpawu, kwaye inokugcina ukusebenza okuzinzileyo kwiindawo ezahlukeneyo ezinzima.

2. Imfuno yendawo yokulahla inkunkuma eqinileyo

Ngokukhawuleziswa kokukhula kwezixeko, inani lenkunkuma eqinileyo eveliswayo liyaqhubeka nokwanda, kwaye unyango lwenkunkuma eqinileyo lube yingxaki engxamisekileyo ekufuneka isonjululwe. Njengendlela eqhelekileyo yonyango, indawo yokulahla inkunkuma eqinileyo inezibonelelo zexabiso eliphantsi kunye nokusebenza okulula, kodwa ikwajongene neengxaki ezifana nokuvuza kunye nongcoliseko. Ke ngoko, indlela yokuqinisekisa ukhuseleko kunye nokukhuselwa kwendalo kwendawo yokulahla inkunkuma eqinileyo ibe yingongoma ebalulekileyo kwicandelo lonyango lwenkunkuma eqinileyo.

3. Imizekelo yokusetyenziswa kwe-geomembrane kwindawo yokulahla inkunkuma eqinileyo

1. Indawo yokulahla inkunkuma

Kwiindawo zokulahla inkunkuma, ii-geomembrane zisetyenziswa kakhulu kumaleko angaphantsi angangeni manzi kunye nomaleko wokukhusela ithambeka. Ngokubeka i-geomembrane ezantsi nakumthambeka wendawo yokulahla inkunkuma, ungcoliseko lwendalo esingqongileyo yi-leachate yokulahlwa kwenkunkuma lunokuthintelwa ngempumelelo. Kwangaxeshanye, indawo ejikelezileyo kwindawo yokulahla inkunkuma inokuqiniswa ngokusebenzisa iindlela ezingangeni manzi, ukwahlula amanzi, ukwahlula kunye nokungahluzi, ukuhambisa amanzi kunye nokuqinisa kusetyenziswa ii-geomembrane, ii-geoclay mats, ii-geotextiles, ii-geogrid kunye nezixhobo ze-geodrainage.
