Geomembrane chinhu chisingapindi mvura uye chinodzivirira chakavakirwa pazvinhu zvakakwirira zvepolymer. Iyo inonyanya kukamurwa kuita yakaderera-density polyethylene (LDPE) geomembrane, yakakwirira-density polyethylene (HDPE) geomembrane, uye EVA geomembrane. Iyo warp yakarukwa composite geomembrane yakasiyana neyakajairwa geomembranes. Chimiro chayo ndechekuti mharadzano yelongitude nelatitude haina kukombama, uye imwe neimwe iri muchimiro chakatwasuka. Sungai mbiri idzi zvakasimba neshinda yakarukwa, inogona kuwiriraniswa zvakaenzana, kumirisana nemasimba ekunze, kugovera kushushikana, uye kana simba rekunze rinoshandiswa richibvarura zvinhu, shinda inoungana pamwe nekutsemuka kwekutanga, ichiwedzera kuramba kubvaruka. Kana warp yakarukwa composite inoshandiswa, shinda yakarukwa inodzokororwa inodzokororwa pakati pemafiber layers ewarp, weft, uye geotextile kuruka zvitatu kuita chimwe. Naizvozvo, iyo warp yakarukwa composite geomembrane ine hunhu hwekusimba kwepamusoro uye kuderera kwakadzika, pamwe nekuita kwekusapinda mvura kwegeomembrane. Naizvozvo, warp knitted composite geomembrane imhando yeanti-seepage zvinhu zvine mabasa ekusimbisa, kuzviparadzanisa nevamwe, uye kudzivirira. Iko kushandiswa kwepamusoro-soro kwe geosynthetic composite zvinhu pasi rese nhasi.
Kusimba kwakasimba, kureba kwakadzika, yunifomu yehurefu uye kuchinjika, kukwirira kwemisodzi, kuramba kupfeka kwakanaka, uye kusamira kwemvura kwakasimba. jira rakarukwa. Iyo anti-seepage performance inonyanya kuenderana ne-anti-seepage performance yefirimu repurasitiki. Mafirimu epurasitiki anoshandiswa anti-seepage application kumba nekune dzimwe nyika anonyanya kusanganisira (PVC) polyethylene (PE) uye ethylene/vinyl acetate copolymer (EVA). Iwo mapolymer makemikari anochinjika zvinhu ane diki chaiyo giravhiti, kuwedzera kwakasimba, kuchinjika kwakanyanya kune deformation, corrosion resistance, kuderera kwekushisa kwekudzivirira, uye kunaka kwechando. Hupenyu hwesevhisi yecomposite geotextile firimu inonyanya kutariswa nekuti firimu repurasitiki rakarasa anti-seepage uye basa rekuvhara mvura. Maererano nemitemo yenyika yeSoviet Union, firimu re polyethylene nehupamhi hwe 0.2m uye stabilizer inoshandiswa mu hydraulic engineering inogona kushanda kwemakore 40-50 pasi pemvura yakachena uye makore 30-40 pasi pemamiriro emvura. Nokudaro, hupenyu hwebasa re geomembrane inosanganiswa yakakwana kuti isangane nezvinoda-seepage zvinodiwa zvedhamu.
