Momwe mungayakire chosanjikiza choteteza cha HDPE geomembrane pomanga anti-seepage?
Kuyika kwa HDPE geomembrane kumatengera kutsetsereka koyamba kenako ndikuyika pansi. Mukayika filimuyo, musamakoke mwamphamvu kwambiri, siyani malire ena kuti muzimira ndi kutambasula. Zolumikizana zopingasa siziyenera kukhala pamtunda wotsetsereka ndipo siziyenera kuchepera 1.5m kuchokera kuphazi la otsetsereka. Zolumikizana zazitali za zigawo zoyandikana siziyenera kukhala pamzere wopingasa womwewo ndipo zidzagwedezeka ndi kupitirira 1m kuchokera kwa wina ndi mzake. Osakoka kapena kukoka geomembrane mwamphamvu mumayendedwe kuti mupewe zinthu zakuthwa kuti zisabowole. Ma ducts a mpweya osakhalitsa amayenera kuyikidwa pansi pa nembanemba kuti achotse mpweya pansi, kuwonetsetsa kuti geomembrane imangiriridwa mwamphamvu kumunsi. Ogwira ntchito yomanga ayenera kuvala nsapato za rabara zofewa kapena nsapato zansalu panthawi yomanga, ndikuyang'ana momwe nyengo ndi kutentha kumakhudzira nembanemba.

Zomangamanga zenizeni ndi izi:

1) Kudula geomembrane: Muyezo weniweni wa kuyika pamwamba uyenera kuchitidwa kuti mupeze miyeso yolondola, ndiyeno kudula molingana ndi m'lifupi osankhidwa ndi kutalika kwa HDPE geomembrane ndi ndondomeko yogona, poganizira za kukula kwa kuwotcherera. Malo ooneka ngati fani pa ngodya ya pansi pa dziwe ayenera kudulidwa moyenerera kuonetsetsa kuti malekezero onse a pamwamba ndi apansi ali okhazikika.

2) Tsatanetsatane wothandizira chithandizo: Musanayike geomembrane, ngodya zamkati ndi zakunja, mapindikidwe olumikizirana ndi zina ziyenera kulimbikitsidwa poyamba. Ngati ndi kotheka, awiri wosanjikiza HDPE geomembrane akhoza welded.

3) Kuyika kotsetsereka: Mayendedwe a filimuyo ayenera kukhala ofanana ndi mzere wotsetsereka, ndipo filimuyo iyenera kukhala yosalala komanso yowongoka kuti ipewe makwinya ndi ma ripples. Geomembrane iyenera kuzikika pamwamba pa dziwe kuti isagwe ndi kutsetsereka pansi.

Chotchinga choteteza pamtunda ndi geotextile yopanda nsalu, ndipo liwiro lake loyika liyenera kukhala logwirizana ndi kuthamanga kwa filimuyo kuti apewe kuwonongeka kwa anthu ku geotextile. Njira yoyakira geotextile iyenera kukhala yofanana ndi ya geomembrane. Zidutswa ziwiri za geotextile ziyenera kulumikizidwa ndikuphatikizana, ndi m'lifupi mwake pafupifupi 75mm molingana ndi kapangidwe kake. Ayenera kusokera pamodzi pogwiritsa ntchito makina osokera a m’manja.

4) Kuyika pansi kwa dziwe: Ikani geomembrane ya HDPE pamtunda wathyathyathya, yosalala komanso yotanuka pang'ono, ndipo mumamatira kwambiri pamtunda kuti mupewe makwinya ndi mafunde. Ma geomembrane awiri ayenera kulumikizidwa ndi kuphatikizika, ndi m'lifupi mwake pafupifupi 100mm molingana ndi kapangidwe kake. Malo owotcherera amayenera kukhala aukhondo.
