Njira yosungira madzi ndi malo ofunikira kwambiri pogawa madzi ndi ulimi wothirira, ndipo njira yosamalira madzi yoletsa kutuluka kwa madzi imagwirizana mwachindunji ndi kukhazikika ndi moyo wa njirayo. M'zaka zaposachedwa, monga mtundu watsopano wa zinthu zoletsa kutuluka kwa madzi, njira yosungira madzi yosakanikirana yakhala ikugwiritsidwa ntchito kwambiri pochiza njira zosungira madzi zoletsa kutuluka kwa madzi. Ndiye, kodi ndi bwino kugwiritsa ntchito njira yosungira madzi yosakanikirana pochiza njira zosungira madzi zoletsa kutuluka kwa madzi? Pepalali lidzasanthula ubwino ndi kuipa kwa njira yosungira madzi yosakanikirana ndi momwe imagwirira ntchito pochiza njira zosungira madzi zoletsa kutuluka kwa madzi.
Choyamba, tiyeni tiwone ubwino wa ma geomembrane a composite. Ma geomembrane a composite amapangidwa ndi ma polymer ambiri a molecular ndi geotextile, omwe ali ndi mphamvu yabwino kwambiri yoletsa kutuluka kwa madzi. Coefficient yake yoletsa kutuluka kwa madzi ndi yochepa, zomwe zingalepheretse kulowa kwa madzi ndikuchepetsa kutaya kwa njira. Kuphatikiza apo, ma geomembrane a composite ali ndi mphamvu yabwino yolimba komanso kutalika pakagwa, zomwe zimatha kusintha kusintha kwa pansi pa njira ndikusunga kukhazikika kwa kapangidwe kake. Nthawi yomweyo, ma geomembrane a composite alinso ndi makhalidwe monga kukana dzimbiri, kukana ukalamba ndi kukana kwa ultraviolet, ndipo angagwiritsidwe ntchito kwa nthawi yayitali pansi pa nyengo zovuta.
Komabe, pali zovuta zina pa ma geomembrane a composite. Choyamba, kapangidwe kake ndi kovuta ndipo kamafuna akatswiri omanga ndi ukadaulo womanga. Kuyika ma geomembrane a composite kuyenera kuonetsetsa kuti pamwamba pa nembanemba pamakhala posalala komanso popapatiza, apo ayi zotsatira zake zotsutsana ndi kutuluka kwa madzi zidzakhudzidwa. Kuphatikiza apo, geomembrane ya composite iyeneranso kusamala kuti isabowole ndi kukanda ndi zinthu zakuthwa panthawi yonyamula ndi kusunga, kuti isawononge umphumphu wake.
Pochiza njira zosungira madzi zomwe sizingalowe m'madzi, kugwiritsa ntchito njira zosungira madzi zomwe zili ndi ma geomembrane kuli ndi ubwino winawake. Choyamba, njira zosungira madzi zomwe zili ndi ma geomembrane zimatha kuletsa kutuluka kwa madzi pansi pa njira ndikuwonjezera mphamvu yosungira madzi komanso kugwiritsa ntchito bwino njira yothirira. Kachiwiri, nthawi yomanga njira zosungira madzi zomwe zili ndi ma geomembrane ndi yochepa, zomwe zingafupikitse nthawi yomanga ndikuchepetsa ndalama zomwe polojekiti imagwiritsa ntchito. Kuphatikiza apo, njira zosungira madzi zomwe zili ndi ma geomembrane zimakhala ndi nthawi yayitali yogwirira ntchito, zomwe zingachepetse kuchuluka kwa kukonza ndi kusintha kwa njira ndikuchepetsa ndalama zosamalira.
Komabe, pochiza njira zosungira madzi zomwe sizingalowe m'madzi, tiyeneranso kusamala ndi zofooka zina za ma geomembrane ophatikizika. Mwachitsanzo, poika geomembrane yophatikizika, ndikofunikira kuonetsetsa kuti pansi pa ngalandeyo ndi lathyathyathya ndipo palibe zinthu zakuthwa zomwe zikutuluka kuti tipewe kubowola pamwamba pa nembanemba. Kuphatikiza apo, geomembrane yophatikizika iyenera kulumikizidwa ndikukhazikika ikayikidwa kuti itsimikizire kuti ndi yolimba komanso yokhazikika. Zofunikira zonse zomangira izi zimafuna kukonzekera bwino komanso kukonzekera bwino musanamange.
Kuphatikiza apo, tiyeneranso kusamala ndi kusintha kwa magwiridwe antchito a ma geomembrane a composite panthawi yogwiritsidwa ntchito kwa nthawi yayitali. Ngakhale kuti geomembrane ya composite ili ndi mawonekedwe okhwima komanso osagwirizana ndi ultraviolet, magwiridwe antchito ake angakhudzidwe pang'ono ngati akumana ndi zachilengedwe monga kuwala kwa dzuwa, mvula ndi nthaka kwa nthawi yayitali. Chifukwa chake, pochiza njira zosungira madzi zomwe sizingalowe, tiyenera kuyang'ana nthawi zonse ndikusunga geomembrane ya composite kuti tiwonetsetse kuti magwiridwe antchito ake ndi olimba komanso okhazikika.
Mwachidule, ili ndi ubwino ndi kugwiritsa ntchito bwino kugwiritsa ntchito geomembrane yopangidwa ndi zinthu zosiyanasiyana pochiza njira zosungira madzi zomwe sizingalowe. Geomembrane yopangidwa ndi zinthu zosiyanasiyana imagwira ntchito yofunika kwambiri pochiza njira zosungira madzi zomwe sizingalowe chifukwa cha ntchito yake yabwino kwambiri yoletsa madzi kulowe, kusinthasintha bwino komanso kukhala ndi moyo wautali. Komabe, tiyeneranso kuzindikira zofooka ndi njira zodzitetezera pakupanga ndi kugwiritsa ntchito ma geomembrane opangidwa ndi zinthu zosiyanasiyana. Chifukwa chake, pakugwiritsa ntchito moyenera, tiyenera kusankha ndikugwiritsa ntchito malinga ndi mikhalidwe inayake, ndikulimbitsa kayendetsedwe ka zomangamanga ndi kukonza kuti tiwonetsetse kuti ma geomembrane opangidwa ndi zinthu zosiyanasiyana amagwira ntchito bwino komanso otetezeka pochiza njira zosungira madzi zomwe sizingalowe madzi.
