Composite geomembrane ndeye geotextile anti-seepage zvinhu zvinoumbwa nefirimu repurasitiki seye anti-seepage substrate uye jira risiri rakarukwa. Iyo anti-seepage performance inonyanya kuenderana ne-anti-seepage performance yefirimu repurasitiki. Mafirimu epurasitiki anoshandiswa anti-seepage application mukati mekunze uye kunze kwenyika kunyanya anosanganisira polyvinyl chloride (PVC), polyethylene (PE), uye ethylene/vinyl acetate copolymer (EVA). Iwo imhando yepolymer kemikari inochinjika zvinhu ine yakaderera chaiyo giravhiti, kuwedzera kwakasimba, kuchinjika kwakakwira kune deformation, corrosion resistance, kuderera kwekushisa kwekudzivirira, uye kunaka kwechando.
Hupenyu hwesevhisi yeakaumbwa geomembranes inonyanya kutsanangurwa kana iyo firimu repurasitiki rinorasikirwa ne-anti-seepage uye inodzivirira mvura. Maererano neSoviet yenyika mitemo, mafirimu e polyethylene ane hupamhi hwe 0.2m uye stabilizers anoshandiswa muinjiniya yemvura anogona kushanda kwemakore 40-50 pasi pemvura yakachena uye makore 30-40 pasi pemamiriro emvura. Nokudaro, hupenyu hwebasa remusanganiswa geomembrane hwakakwana kuti usangane ne-anti-seepage zvinodiwa zvedhamu.
Chikamu che geomembrane
Dhamu redhamu pakutanga raive dhamu remadziro, asi nekuda kwekudonha kwedhamu, chikamu chepamusoro chemudhuri wepakati chakabviswa. Kugadzirisa dambudziko rekumusoro anti-seepage, anti-seepage inclined wall yakatanga kuwedzerwa. Zvinoenderana nekuongororwa kwekuchengetedza uye kuongororwa kwedhamu reZhoutou Reservoir, kuitira kugadzirisa kusasimba kwemvura uye kudonha kwedhamu kwedhamu kwakakonzerwa nekudonha kwakawanda kwedhamu, nhanho dzekumira dzakamira dzakamira senge bedrock curtain grouting, kubata kumeso grouting, kutsvaira uye kubata sleeve zvakanaka backfilling keteni, uye high-pressure spray anti-seepage plate wall yakagamuchirwa. Rusvingo rwakarerekera rwepamusoro rwakafukidzwa necomposite geomembrane ye-anti-seepage, uye yakabatana kune yakatwasuka anti-seepage mudhuri pazasi, inosvika pakakwirira 358.0m (0.97m pamusoro pecheki mafashamo).
basa guru
1. Kubatanidza anti-seepage uye drainage mabasa, ukuwo uine mabasa akadai sekuzviparadzanisa nevamwe uye kusimbisa.
2. High composite simba, high peel simba, uye yakakwirira puncture kuramba.
3. Yakasimba yekudhonza mvura, yakakwirira friction coefficient, uye yakaderera mutsara wekuwedzera coefficient.
