Semhando nyowani yepolymer zvinhu, composite geomembrane inoshandiswa zvakanyanya muhydraulic engineering uye engineering yekudzivirira kwezvakatipoteredza. Nzira dzekubatanidza dzemusanganiswa geomembrane uye membrane dzinosanganisira nzira dzakasiyana senge lap joint, bonding uye welding. Nekuda kwekukurumidza kushanda kwayo kumhanya uye dhigirii rekugadzira michina, kuvaka welding kunogona kuderedza zvakanyanya huwandu hwevashandi vepa-saiti uye kupfupisa nguva yekuvaka, uye zvishoma nezvishoma yave nzira huru yekuisa pa-saiti uye kuvaka kwecomposite geomembranes. Welding nzira dzinosanganisira electric wedge, hot melt extrusion uye yakanyanya tembiricha gasi welding.
Pakati pavo, electric wedge welding ndiyo inonyanya kushandiswa. Nyanzvi dzemudzimba uye nyanzvi dzakaita tsvakiridzo yakadzama pane inopisa wedge welding tekinoroji uye vakawana imwe rondedzero yenguva dzose uye yehuwandu zviratidzo. Zvinoenderana neakakodzera bvunzo dzemunda, kusimba kwekusimba kweiyo composite geomembrane yakabatana inopfuura 20% yesimba reiyo base zvinhu, uye kuputsika kunowanzoitika pane isina-weld chikamu che weld edge. Zvisinei, kunewo mamwe maekisenisi ane simba rekutadza kusimba riri kure nezvinodiwa zvekugadzira kana chikamu chakatyoka chinotanga zvakananga kubva kune weld chinzvimbo. Iyo inobata zvakananga kuitika kweiyo anti-seepage mhedzisiro yeiyo composite geomembrane. Kunyanya mukugadzira geomembrane inosanganiswa, kana welding ikaitika, kutaridzika kwe weld kunosangana nezvinodiwa zvekugadzira, asi simba rekusimba reweld rinowanzotadza kusangana nezvinodiwa zvekugadzira, uye panogona kunge pasina matambudziko munguva pfupi. Zvisinei, tichifunga nezvekugara kwepurojekiti, inobata zvakananga kuzadzikiswa kwehupenyu hunopesana nepeji yeprojekti. Kana pane chinetso, migumisiro yacho inogona kuva yakakomba zvikuru.
Kuti izvi zviitike, isu takatsvaga nekuongorora kuvakwa kwewelding yeHDPE composite geomembrane, uye takaisa matambudziko akajairika mukuita kwekuvaka, kuitira kuti tiite tsvakiridzo yekusiyanisa uye kuona matanho ekuvandudza mhando. Matambudziko emhando yakajairika mukuvaka kwecomposite geomembrane welding anonyanya zvinosanganisira kuwandisa kwewelding, kuwandisa welding, kushaikwa welding, kuunyana, uye partial welding ye weld bead.
