Itanki yokugcina isetyenziselwa ukugcina ulwelo okanye igesi yentsimbi etywiniweyo isikhongozeli, itanki yokugcina ubunjineli yipetroleum, imichiza, ingqolowa neoyile, ukutya, ukukhuselwa komlilo, uthutho, isinyithi, ukhuselo lwesizwe kunye namanye amashishini abalulekileyo asisiseko, iimfuno zawo ezisisiseko nazo zingqongqo kakhulu. . Umaleko womhlaba wesiseko kufuneka ufezekise iimfuno zexabiso loyilo lomthamo wokuthwala, kwaye kufuneka uphathwe nge-seapage kunye nobungqina bokufuma, ngaphandle koko ukuvuza kuya kubangela ungcoliseko olukhulu kwindalo, kwaye umphunga wamanzi angaphantsi komhlaba uya kunyuka, kwaye itanki yentsimbi iya kuba nomhlwa. Ke ngoko, itanki yeoli ye-HDPE i-geomembrane enganyangekiyo yinto engabonakaliyo kunye nobungqina bokufuma kuyilo olusisiseko lwetanki yokugcina.
Indawo yetanki ye-oyile ibeka itekhnoloji yolwakhiwo lwe-geomembrane olungagungqiyo:
1. Ngaphambi kokuba itanki ye-oyile i-geomembrane engagxumekiyo ibekwe, isatifikethi esihambelanayo sokwamkelwa kobunjineli boluntu siya kufunyanwa.
2. Ngaphambi kokusika, imilinganiselo echaphazelekayo kufuneka ilinganiswe ngokuchanekileyo, i-HDPE i-geomembrane kufuneka inqunywe ngokweyona ndlela yokusika, ngokuqhelekileyo kungekhona ngokuhambelana nobukhulu obubonisiweyo, kufuneka ibalwe nganye nganye, kwaye irekhodwe ngokubanzi kwifom ekhethekileyo.
3. Kufuneka azame ukuwelda ngaphantsi, phantsi kwesiseko sokuqinisekisa umgangatho, kangangoko kunokwenzeka ukugcina imathiriyeli ekrwada. Kwakhona kulula ukuqinisekisa umgangatho.
4. Ububanzi bomthungo phakathi kwefilimu kunye nefilimu ngokuqhelekileyo abukho ngaphantsi kwe-10cm, ngokuqhelekileyo ukwenzela ukuba ukulungelelaniswa kwe-weld kuhambelane ne-slope, oko kukuthi, kunye ne-slope.
5. Ngokuqhelekileyo kwiikona kunye namacandelo akhubazekileyo, ubude be-seam kufuneka bube bufutshane ngokusemandleni. Ngaphandle kweemfuno ezikhethekileyo, kwiithambeka ezinamathambeka amakhulu kune-1: 6, ngaphakathi kwe-1.5 yeemitha ze-slope ephezulu okanye indawo yoxinzelelo, zama ukungafaki i-welds.
6. Ekubekeni itanki yeoli ifilimu engabonakaliyo, iifolthi ezenziweyo kufuneka zigwenywe. Xa iqondo lobushushu lisezantsi, kufuneka liqiniswe kwaye ligalelwe ithala kangangoko kunokwenzeka.
7. Emva kokugqitywa kwe-geomembrane engabonakaliyo yokubeka, ukuhamba phezu kwe-membrane, izixhobo ezihambayo, njl. Kufuneka kuncitshiswe. Izinto ezinokubangela ingozi kwi-membrane engabonakaliyo akufanele zibekwe kwi-membrane okanye ziqhutywe kwi-membrane ukuze zigweme umonakalo wengozi kwi-membrane.
