Geomembrane a i ʻole geomembrane i hui ʻia ma ke ʻano he mea impermeable

Ma ke ʻano he anti-seepage material, geomembrane a i ʻole geomembrane composite he impermeability wai maikaʻi, a hiki ke hoʻololi i ka pā pālolo kumu, anti-seepage inclined wall a me anti-silo ma muli o kāna mau pono o ka māmā, maʻalahi o ke kūkulu ʻana, haʻahaʻa haʻahaʻa a me ka hana hilinaʻi.Hoʻohana nui ʻia ka geomembrane geomembrane i ka ʻenekinia hydraulic a me ka ʻenehana geotechnical.

ʻO ka geomembrane composite he geotextile i hoʻopili ʻia i hoʻokahi a i ʻole ʻelua ʻaoʻao o ka membrane e hana i kahi geomembrane composite.Hoʻokahi lole a me hoʻokahi kiʻiʻoniʻoni kona ʻano, ʻelua lole a me hoʻokahi kiʻiʻoniʻoni, ʻelua kiʻiʻoniʻoni a me hoʻokahi lole, etc.

Hoʻohana ʻia ka geotextile ma ke ʻano he pale pale o ka geomembrane e pale i ka papa impermeable mai ka pōʻino.I mea e hōʻemi ai i ka radiation ultraviolet a hoʻonui i ka hana anti-aging, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ke ala kanu e waiho ai.

I ka wā o ke kūkulu ʻia ʻana, pono e hoʻohana ʻia ke one a i ʻole ka pālolo me kahi anawaena liʻiliʻi e hoʻohaʻahaʻa i ka ʻili o ke kumu, a laila kau i ka geomembrane.ʻAʻole pono e kikoo paʻa loa ka geomembrane, a ʻo ke kino lepo i kanu ʻia ma nā ʻaoʻao ʻelua ua corrugated, a laila kau ʻia kahi papa o kahi 10cm transition layer ma luna o ka geomembrane me ke one maikaʻi a i ʻole ka pālolo.Hoʻokumu ʻia kahi pōhaku poloka 20-30cm (a i ʻole poloka paʻa i hana mua ʻia) ma ke ʻano he papa pale hopena.I ka wā o ke kūkulu ʻana, e hoʻāʻo e pale i ka paʻi pololei ʻana o nā pōhaku i ka geomembrane, ʻoi aku ka maikaʻi i ka wā e waiho ana i ka membrane i ka wā e hana ana i ke kūkulu ʻana i ka papa pale.Pono e hoʻopaʻa ʻia ka pilina ma waena o ka geomembrane composite a me nā hale a puni e nā bolts hoʻonui a me nā ʻupena pā kila, a pena ʻia nā ʻāpana pili me ka asphalt emulsified (mānoanoa 2mm) e pale i ka leakage.
