Kucheka uye kutakura: Zvichienderana nemarekodhi ekuyerwa kwenzvimbo yekuisa, rekodha nhamba yebundle hombe ye geomembrane yakachekwa uye kuendesa kunzvimbo yekuisa zvinoenderana nenhamba. Chenjerera, usakweva kana kudhonza nechisimba geomembrane panguva yekufambisa kudzivirira zvinhu zvakapinza kubva pakuiboora.
Kuvaka uye kuiswa kwegeomembrane kuisa:
1) Inofanira kubva pasi kusvika panzvimbo yakakwirira, pasina kudhonza zvakasimba, ichisiya muganhu we 1.50% yekunyura kwemunharaunda uye kutambanudza. Tichifunga nezvemamiriro chaiwo echirongwa ichi, materu achaiswa munhevedzano yepamusoro-soro.
2) Majoini ehurefu emafuremu ari padhuze haafanire kunge ari pamutsetse wakachinjika wakafanana uye anofanirwa kudzikamiswa neanopfuura 1M kubva kune mumwe.
3) Iyo longitudinal joint inofanirwa kunge iri 1.50m kubva padhamu tsoka uye inokotama tsoka, uye inofanira kuiswa panzvimbo yakati sandara.
4) Tanga nechekumashure kuzasi kwemateru kutanga.
5) Paunenge uchiisa mutsetse, kutungamira kwefirimu kunofanira kunge kwakafanana nemutsara wemateru.
Slope kuisa: Usati waisa anti-seepage geomembrane pamateru, nzvimbo yekuisa inofanira kuongororwa uye kuyerwa. Zvichienderana nehukuru hwakayerwa, iyo anti-seepage membrane inoenderana nehukuru mudura inofanira kutakurwa kuenda kuchikamu chekutanga chekumisikidza mugero chikuva. Panguva yekuisa, nzira yakakodzera ye "kusundira nekuisa" kubva kumusoro kusvika pasi inofanira kugamuchirwa maererano nemamiriro chaiwo ari panzvimbo. Munzvimbo yefan-shaped, inofanirwa kutemwa zvine musoro kuti ive nechokwadi chekuti zvese zvekumusoro nezasi zvakasungwa zvakasimba.
Pazasi kuisa: Usati waisa anti-seepage geomembrane, nzvimbo yekuisa inofanira kuongororwa uye kuyerwa. Zvichienderana nehukuru hwakayerwa, iyo anti-seepage membrane inoenderana nehukuru mudura inofanira kutakurwa kuenda kunzvimbo inoenderana. Pakuisa, inosundirwa nemaoko kune imwe nzira. Kurongeka uye kurongeka: Kuiswa kweHDPE geomembrane, kungave pamateru kana pazasi pesaiti, kunofanirwa kuve kwakatsetseka uye kwakatwasuka, kudzivirira makwinya uye ripples, kuitira kuwiriranisa uye kuenzanisa iwo maviri geomembranes. Iyo yakatarisana hupamhi inowanzo 10cm pamativi ese ari maviri zvinoenderana nezvinodiwa zvekugadzira.
Firimu kudzvanya: Shandisa masaga ejecha kudzvanya panguva yakakodzera uye yakamisikidzwa HDPE geomembrane kudzivirira mhepo uye kudhonza.
Kuisa mugomba rekumisa: Imwe chiyero che anti-seepage membrane inofanira kuchengetwa pamusoro pegomba rekumisa zvinoenderana nezvinodiwa zvekugadzira kugadzirira kunyura kwenzvimbo nekutambanudza.
Longitudinal joint: Chikamu chekukwira chiri pamusoro, chikamu chekudzika chiri pazasi, uye pane zvakakwana kupindirana kureba=15cm. Mushure mekugamuchirwa kwebentonite pad kuisa, nzvimbo yacho inoiswa nemaoko mune imwe nzira.
