Njengohlobo olutsha lwezinto zepolymer, i-geomembrane edibeneyo isetyenziswa ngokubanzi kubunjineli be-hydraulic kunye nobunjineli bokukhuselwa kwendalo. Iindlela zokudibanisa i-geomembrane edibeneyo kunye ne-membrane ziquka iindlela ezahlukeneyo ezifana ne-lap joint, i-bonding kunye ne-welding. Ngenxa yesantya esikhawulezayo sokusebenza kunye nenqanaba eliphezulu lomatshini, ukwakhiwa kwe-welding kunokunciphisa kakhulu inani labasebenzi kwisiza kunye nokunciphisa ixesha lokwakha, kwaye ngokuthe ngcembe ibe yeyona ndlela iphambili yokufakela kwisiza kunye nokwakhiwa kwee-geomembranes ezihlanganisiweyo. Iindlela ze-welding ziquka i-wedge yombane, i-hot melt extrusion kunye ne-welding yegesi ephezulu yokushisa.
Phakathi kwabo, i-wedge yombane isetyenziswa kakhulu. Iingcali zasekhaya kunye nabaphengululi baye benza uphando olunzulu kwitekhnoloji ye-welding eshushu kwaye bafumana inkcazo rhoqo kunye nezalathi zobungakanani. Ngokweemvavanyo zentsimi echaphazelekayo, amandla okuqina okudibanisa i-geomembrane edibeneyo ingaphezulu kwe-20% yamandla ezinto ezisisiseko, kwaye i-fracture ininzi iyenzeka kwi-weld edge ye-weld edge. Nangona kunjalo, kukwakho ezinye iisampulu ezingamandla okusilela kokuqina akude kwiimfuno zoyilo okanye indawo eyaphukileyo iqala ngokuthe ngqo kwindawo ye-weld. Ichaphazela ngokuthe ngqo ukufezekiswa kwempembelelo ye-anti-seepage ye-geomembrane edibeneyo. Ngokukodwa kwi-welding ye-geomembrane edibeneyo, ukuba i-welding iyenzeka, imbonakalo ye-weld ihlangabezana neemfuno zoyilo, kodwa amandla okuqina e-weld ahlala engaphumeleli ukuhlangabezana neemfuno zoyilo, kwaye kungabikho iingxaki kwixesha elifutshane. Nangona kunjalo, ngokuqwalasela ukuqina kweprojekthi, kuya kuchaphazela ngokuthe ngqo ukufezekiswa kobomi obuchasayo beprojekthi. Ukuba kukho ingxaki, imiphumo isenokuba mibi ngakumbi.
Ukuza kuthi ga ngoku, silandele kwaye sihlalutye ukwakhiwa kwe-welding ye-HDPE edibeneyo ye-geomembrane, kwaye sahlula iingxaki eziqhelekileyo kwinkqubo yokwakha, ukwenzela ukuba kuqhutywe uphando lokwahlula kunye nokufumana amanyathelo okuphucula umgangatho. Iingxaki zomgangatho oqhelekileyo kulwakhiwo lwe-welding ye-geomembrane ehlanganisiweyo ikakhulu ibandakanya ukuwelda okugqithisileyo, ukuwelda okugqithisileyo, ukuwelda okulahlekileyo, ukushwabana, kunye nokuwelda inxenye ye-weld bead.
