Ngaba inethiwekhi yokukhupha amanzi edibeneyo enamacala amathathu inokuthintela ukuthuthwa kwenkunkuma?

Inethi yokukhupha amanzi edityanisiweyo enemilinganiselo emithathu isetyenziswa kakhulu kwimisebenzi emikhulu. Ngoko ke, ingaba ingathintela ukudumba kwenhlabathi?

I. Iimpawu zezinto kunye nendlela yokulwa nodaka

Inethi yokukhupha amanzi edityanisiweyo enamacala amathathu yenziwe ngenethi yeplastiki enamacala amathathu ene-geotextile ebotshelelwe emacaleni amabini, ngoko ke ukusebenza kwayo kokukhupha amanzi kulungile kakhulu. Ingaphakathi layo yi-geonet core enamacala amathathu, equlathe i-rib etyebileyo ethe nkqo kunye ne-rib etyebileyo phezulu nasezantsi ukwenza i-drainage channel esebenzayo. Iimbambo ezicwangciswe ngomgca omnye azinakuphucula kuphela uzinzo lwesakhiwo, kodwa zikwathintela i-geotextile ukuba ingene kwi-drainage channel, kwaye zigcine ukusebenza kokukhupha amanzi okuphezulu nokuba ziphantsi kwemithwalo ephezulu.

Ke ngoko, inokukhupha amanzi ngokukhawuleza ngexesha lokukhupha amanzi, kwaye ingasebenzisa nesiphumo sokungahluzi se-geotextile ukuthintela amasuntswana omhlaba ukuba angangeni kumjelo wokukhupha amanzi, nto leyo enokuthintela ukugcwala kwetyuwa. Inethi yokukhupha amanzi edityanisiweyo enamacala amathathu ikwanayo nokumelana okuhle nokugqwala kunye nokumelana ne-asidi kunye ne-alkali, ngoko ke ubomi bayo benkonzo bude.

II. Imizekelo yemigaqo yokusebenza kunye neyokusetyenziswa

Kwimisebenzi ebonakalayo, inethi yokukhupha amanzi edibeneyo enamacala amathathu inokusombulula iingxaki zokukhupha amanzi ezindleleni, kwiibhedi zeendlela, kwiitonela nakwezinye iiprojekthi ngokusebenzisa indlela yayo eyahlukileyo yokukhupha amanzi. Umzekelo, kwiiprojekthi zeendlela, ukuyibeka phantsi komphezulu wendlela kunokukhupha amanzi ngokukhawuleza kwisakhiwo somphezulu wendlela kwaye kuthintele ukufuma ukuba kungangeni kwibhedi yendlela, nto leyo ebangela ukuba ibhedi yendlela ithambe okanye yonakale. Isiphumo sayo sokungahluzi sinokuthintela amasuntswana omhlaba okwibhedi yendlela ukuba angangeni kwinkqubo yokukhupha amanzi kwaye kugcine umjelo wokukhupha amanzi ungaphazanyiswa.

Kwiindawo zokulahla inkunkuma, ayinakusebenza nje kuphela njengomaleko wokukhupha amanzi angaphantsi komhlaba ukuze ikhuphe amanzi angaphantsi komhlaba ngokukhawuleza kwindawo yokulahla inkunkuma, kodwa ikwasebenza njengoqokelelo lwe-leachate kunye nomaleko wokukhupha amanzi ukuze iqokelele kwaye ikhuphe i-leachate eveliswa ngexesha lenkqubo yokulahla inkunkuma. Kule nkqubo, ukusetyenziswa kwayo okudibeneyo kunye nee-geotextiles ezingalukwanga kunokuphucula amandla ayo okulwa nokuvaleka, kuqinisekise ukukhutshwa kwe-leachate ngokulungeleleneyo, kwaye kuthintele ungcoliseko lokusingqongileyo olubangelwa kukuvaleka.

Njengoko kunokubonwa koku kungasentla, inethi yokukhupha amanzi edibeneyo enamacala amathathu inokuthintela ukuvaleka. Ayinakusombulula nje kuphela iingxaki zokukhupha amanzi ezindleleni, kwiindlela, kwiitonela nakwezinye iiprojekthi, kodwa ikwadlala indima ebalulekileyo kwiindawo ezikhethekileyo ezifana neendawo zokulahla inkunkuma.
