Maitiro ekuisa iyo HDPE geomembrane yekudzivirira layer mu anti-seepage kuvaka?
Kuiswa kweHDPE geomembrane kunotora kutevedzana kwemateru kutanga uyezve pazasi padziva. Paunenge uchiisa iyo firimu, usaikweva zvakanyanya, siya imwe margin yekunyura kwenzvimbo uye kutambanudza. Majoini akachinjika haafanire kunge ari pamusoro pemateru uye haafanire kunge ari pasi pe1.5m kubva patsoka yemateru. Majoini ehurefu ezvikamu zviri pedyo haazove pamutsetse wakachinjika wakafanana uye achadzika nekudzika kupfuura 1m kubva kune mumwe. Usakweva kana kudhonza nechisimba geomembrane panguva yekufambisa kudzivirira zvinhu zvinopinza kuti zvisaiboore. Maduta emhepo enguva pfupi anofanirwa kuve akaiswa pasi pe membrane kuti abvise mweya pasi, kuve nechokwadi chekuti geomembrane yakanyatso kusungirirwa kune base layer. Vashandi vekuvaka vanofanirwa kupfeka shangu dzerabha dzakapfava kana bhutsu dzemachira panguva yekuvaka, uye kutarisisa kukanganiswa kwemamiriro ekunze uye tembiricha pane membrane.
Matanho chaiwo ekugadzira ndeaya anotevera:
1) Kucheka geomembrane: Iyo chaiyo kuyerwa kwenzvimbo yekuisa inofanira kuitwa kuti iwane zviyero zvakaringana, uye wozocheka zvinoenderana nehupamhi hwakasarudzwa uye kureba kweiyo HDPE geomembrane uye chirongwa chekuisa, tichifunga nezve hupamhi hwepamusoro hwekushongedza. Nzvimbo yakaita sefan pakona yepasi pedziva inofanira kuchekwa zvine mutsindo kuti ive nechokwadi chekuti migumo yose yekumusoro neyezasi yakadzikwa zvakasimba.
2) Tsanangudzo yekuvandudza kurapwa: Usati waisa geomembrane, iyo yemukati nekunze makona, deformation majoini uye zvimwe zvinhu zvinofanirwa kuvandudzwa kutanga. Kana zvichidikanwa, kaviri-layer HDPE geomembrane inogona kuvezwa.
3) Slope yekuisa: Iyo bhaisikopo inotungamira inofanirwa kuenderana neyakatsetseka mutsara, uye iyo firimu inofanirwa kuve yakati sandara uye yakatwasuka kudzivirira makwinya uye ripples. Iyo geomembrane inofanira kusungirirwa pamusoro pedziva kuti irege kudonha uye kutsvedza ichidzika.
Iyo inodzivirira layer pamateru haina-yakarukwa geotextile, uye kumhanya kwayo kwekuisa kunofanirwa kuenderana neiyo firimu kuisa kumhanya kudzivirira kukuvadzwa kwevanhu kune geotextile. Iyo yekuisa nzira ye geotextile inofanirwa kufanana neye geomembrane. Zvidimbu zviviri zve geotextile zvinofanirwa kurongeka uye kupindirana, nehupamhi hunosvika 75mm zvinoenderana nezvinodiwa zvekugadzira. Dzinofanirwa kusonerwa pamwe chete pachishandiswa muchina wekusona unobatwa neruoko.
4) Kuisa pazasi pedziva: Isa iyo HDPE geomembrane pachigadziko chakati sandara, yakatsetseka uye ine mwero elastic, uye yakanyatso kunamatira kune ivhu repamusoro kudzivirira makwinya uye ripples. Ma geomembranes maviri anofanirwa kurongeka uye kupindirana, nehupamhi hunosvika 100mm zvinoenderana nezvinodiwa zvekugadzira. Nzvimbo yewelding inofanira kuchengetwa yakachena.
