Kushandiswa kwe geomembrane munzvimbo dzakaoma dzemarara

Geomembrane, senzira yeinjiniya inoshanda uye yakavimbika, inoshandiswa zvakanyanya mumunda wemarara akasimba. Hunhu hwayo hwepanyama nemakemikari hunoita kuti ive rutsigiro rwakakosha mumunda wekurapa marara akasimba. Chinyorwa chino chichakurukura zvakadzama nezvekushandiswa kwegeomembrane mumarara akasimba kubva pazvinhu zvema geomembrane, zvinodiwa mumarara akasimba, mienzaniso yekushandiswa, mhedzisiro yekushandiswa uye mafambiro ekuvandudza egeomembrane mumarara akasimba mune ramangwana.

1. Hunhu hwe geomembrane

Geomembrane, inonyanya kugadzirwa nepolymer yakakura yemamorekuru, ine hunhu hwakanaka hwemvura isingapindi mvura uye inodzivirira kubuda kwemvura. Ukobvu hwayo hunowanzova 0.2 mm Kusvika 2.0 mm Pakati, inogona kugadziriswa zvichienderana nezvinodiwa zveinjiniya. Pamusoro pezvo, geomembrane inewo hunhu hwakanaka hwemakemikari hwekudzivirira ngura, hunodzivirira kukwegura, hunodzivirira kupfeka nezvimwe zvinhu, uye inogona kuchengetedza kushanda kwakasimba munzvimbo dzakasiyana-siyana dzakaoma.

2. Kudiwa kwenzvimbo yekurasira marara

Nekukurumidza kwekukura kwemaguta, huwandu hwemarara akagadzirwa huri kuramba huchiwedzera, uye kurapwa kwemarara akasimba kwave dambudziko guru rinofanira kugadziriswa. Senzira yakajairika yekurapa, nzvimbo yekurasira marara ine zvakanakira zvemutengo wakaderera uye nyore kushandisa, asi inosanganawo nematambudziko akadai sekubuda kwemvura uye kusvibiswa. Saka, maitiro ekuona kuti marara akachengeteka uye kuchengetedzwa kwezvakatipoteredza ave nyaya yakakosha munyaya yekurapa marara akasimba.

3. Mienzaniso yekushandiswa kwe geomembrane mumarara akaomarara

1. Nzvimbo yekurasira marara

Munzvimbo dzemarara, ma geomembrane anoshandiswa zvakanyanya muchikamu chepasi chisingapindi mvura uye chikamu chekudzivirira mawere. Nekuisa geomembrane pasi nepamucheto penzvimbo yemarara, kusvibiswa kwezvakatipoteredza nekudonhedzwa kwemarara kunogona kudzivirirwa zvinobudirira. Panguva imwe chete, nzvimbo yakakomberedza iri mudura inogona kusimbiswa nekushandisa nzira dzinodzivisa kuyerera kwemvura, kupatsanura mvura, kupatsanura uye kudzivirira kusvina, kudhonza mvura nekusimbisa uchishandisa ma geomembrane, ma geoclay mats, ma geotextiles, geogrid uye geodrainage materials.
