Kugwiritsa ntchito geomembrane m'malo otayira zinyalala zolimba

Geomembrane, monga chida chothandiza komanso chodalirika chaukadaulo, imagwiritsidwa ntchito kwambiri pantchito yotaya zinyalala zolimba. Kapangidwe kake kapadera ka thupi ndi mankhwala kamapangitsa kuti ikhale chithandizo chofunikira pantchito yochotsa zinyalala zolimba. Nkhaniyi ikambirana mozama za momwe geomembrane imagwiritsidwira ntchito potaya zinyalala zolimba kuchokera ku mbali za mawonekedwe a geomembrane, zosowa za malo otayira zinyalala zolimba, zitsanzo za momwe mungagwiritsire ntchito, zotsatira za momwe geomembrane imagwiritsidwira ntchito komanso momwe zinthu zikuyendera mtsogolo pakukula kwa malo otayira zinyalala zolimba.

1. Makhalidwe a geomembrane

Geomembrane, makamaka yopangidwa ndi polima ya molekyulu yambiri, ili ndi mphamvu zabwino kwambiri zosalowa madzi komanso zoletsa kutuluka kwa madzi. Makulidwe ake nthawi zambiri amakhala 0.2 mm Mpaka 2.0 mm Pakati, imatha kusinthidwa malinga ndi zosowa zaukadaulo. Kuphatikiza apo, geomembrane ilinso ndi mphamvu zabwino zotsutsana ndi dzimbiri la mankhwala, kukana ukalamba, kukana kuvala ndi zina, ndipo imatha kusunga magwiridwe antchito okhazikika m'malo osiyanasiyana ovuta.

2. Kufunika kwa malo otayira zinyalala zolimba

Chifukwa cha kufulumira kwa kukula kwa mizinda, kuchuluka kwa zinyalala zolimba zomwe zimapangidwa kukupitirirabe kukwera, ndipo kukonza zinyalala zolimba kwakhala vuto lofunika kuthetsedwa mwachangu. Monga njira yodziwika bwino yosamalira zinyalala zolimba, malo otayira zinyalala zolimba ali ndi ubwino wotsika mtengo komanso wosavuta kugwiritsa ntchito, komanso akukumana ndi mavuto monga kutuluka kwa madzi ndi kuipitsidwa. Chifukwa chake, momwe mungatsimikizire chitetezo ndi kuteteza chilengedwe cha malo otayira zinyalala zolimba kwakhala nkhani yofunika kwambiri pankhani yosamalira zinyalala zolimba.

3. Zitsanzo za kugwiritsa ntchito geomembrane m'malo otayira zinyalala zolimba

1. Malo otayira zinyalala

Mu malo otayira zinyalala, ma geomembrane amagwiritsidwa ntchito kwambiri mu gawo losalowa madzi pansi ndi gawo loteteza malo otayira zinyalala. Mwa kuyika geomembrane pansi ndi pamalo otayira zinyalala, kuipitsa chilengedwe chozungulira ndi leachate ya zinyalala kungapewedwe bwino. Nthawi yomweyo, malo ozungulira omwe ali mu malo otayira zinyalala amatha kuwonjezeredwa pogwiritsa ntchito njira zoletsa kutuluka kwa madzi, kulekanitsa madzi, kulekanitsa madzi ndi kuletsa kusefa, kukhetsa madzi ndi kulimbitsa pogwiritsa ntchito ma geomembrane, ma geoclay mat, ma geotextiles, geogrid ndi zinthu zoyeretsera madzi.
