ʻO Geosynthetics kahi huaʻōlelo maʻamau no nā mea synthetic i hoʻohana ʻia i ka ʻenekinia kīwila. Ma ke ʻano he ʻenekinia kīwila, hoʻohana ʻo ia i nā polymers synthetic (e like me nā plastics, nā fibers chemical, synthetic rubber, etc.) ma ke ʻano he mea maka no ka hana ʻana i nā ʻano huahana like ʻole, i waiho ʻia i loko o ka lepo, ma ka ʻili a ma waena o nā ʻano lepo. , e pāʻani i ka hana o ka wai a me ka anti-seepage, hoʻoikaika, hoʻokahe a me ka kānana a me ka hoʻihoʻi ʻana i ka ecological.
Ka nānā ʻana o ka loko huelo
1. Hydrology
Aia ma ke awāwa kekahi loko iʻa maina keleawe. Aia nā kualono ma ka ʻaoʻao ʻākau, komohana a me ka hema i hoʻokaʻawale ʻia mai ka ʻōnaehana wai a puni. He 5km² ka nui o ka loko wai huelo. Aia ka wai i loko o ka ʻauwai a puni ka makahiki, a nui ke kahe o ka wai.
2. Topography
Aia ke awāwa ma ke komohana akau-hema hikina, a huli i ka hikina akau ma ka ʻāpana Mizokou. Ua hamama ke awawa, me ka laula awelika ma kahi o 100m a he 6km ka loa. Aia ka pā wai mua o ka loko wai huelo i manaʻo ʻia ma waenakonu o ke awāwa. ʻO ke kiʻekiʻe o ka pali he pali a ʻo ka slope maʻamau he 25-35 °, ʻo ia ka ʻāina alpine denudation tectonic.
3. ʻEnekinia nā kūlana honua
I ka hoʻolālā ʻana i ka hoʻolālā anti-seepage no ka loko iʻa huelo, pono e hana mua ʻia ka ʻike ʻenehana ʻenekinia o ka wahi wai. Ua ho'okō ka 'oihana hana i ka 'enekinia ho'ona'auao honua o ka loko i'a huelo: 'a'ohe hewa e hele ana ma loko o ka waihona; ʻO ka lepo paʻa, ʻo ke kahua kūkulu hale ʻo Class II; ʻo ka wai o ka lepo i loko o ka ʻāpana waihona e hoʻomalu ʻia e ka wai māwae i hoʻomaloʻo ʻia; paʻa ka papa pōhaku, a aia kahi mānoanoa ikaika i ka ʻāina i puʻunaue ʻia ma ka wahi o ka pā, me ka ikaika mechanical kiʻekiʻe. Hoʻoholo piha ʻia he kahua paʻa ke kahua o ka hana huelo a kūpono maoli no ke kūkulu ʻana i hale waihona.
ʻO ka papahana anti-seepage o ka loko huelo
1. Ke koho ʻana i nā mea anti-seepage
I kēia manawa, ʻo nā mea anti-seepage artificial i hoʻohana ʻia i ka papahana he geomembrane, sodium bentonite waterproof blanket, a me nā mea ʻē aʻe. waiho ʻia me ka pākeʻe wai wai sodium bentonite.
2. Pūnaehana hoʻoheheʻe wai o lalo
Ma hope o ka hoʻomaʻemaʻe ʻia ʻana a mālama ʻia ka lalo o ka waihona, waiho ʻia kahi papa ʻiliʻili mānoanoa 300mm ma lalo o ka waihona e like me kahi papa hoʻoheheʻe wai honua, a hoʻonoho ʻia kahi ʻauwai makapō no ka hoʻoheheʻe ʻana ma lalo o ka waihona, a me kahi paipu perforated DN500. waiho ʻia i loko o ka ʻauwai makapō i alakaʻi nui no ka hoʻoheheʻe ʻana. Hoʻonoho ʻia nā ʻauwai makapō no ka hoʻoheheʻe alakaʻi ma ka pali ma lalo o ka loko huelo. He 3 auwai makapo ka huina, a ua hoonohonoho ia ma ka hema, waena a me ka akau o ka loko.
3. Pūnaehana hoʻoheheʻe wai lepo
I loko o ka wahi e hoʻoheheʻe ʻia ai ka wai honua, ua waiho ʻia kahi pūnaewele hoʻoheheʻe geotechnical composite, a ua hoʻonohonoho ʻia nā ʻauwai makapō a me nā paipu lālā hoʻoheheʻe i loko o kēlā me kēia ʻauwai lālā i loko o ka waihona, i hoʻopili ʻia i ka paipu nui ma lalo o ka waihona.
4. Anti-seepage waiho mea
Hoʻohana ʻia ka mea kūʻē i ka ʻike ʻana i ka wai i loko o ka waihona wai huelo i ka pale pale wai bentonite. Ma ka lalo o ka loko wai huelo, ua hoʻonohonoho ʻia kahi papa hoʻoheheʻe wai lepo. Ke noʻonoʻo nei i ka pono o ka pale ʻana i ka pākeʻe wai wai sodium bentonite, ua waiho ʻia kahi lepo 300mm mānoanoa ma luna o ka ʻiliʻili ma ke ʻano he pale pale ma lalo o ka membrane. Ma ka pali, ua hoʻonohonoho ʻia kahi ʻupena hoʻokaʻawale geotechnical composite ma kekahi mau wahi e like me ka papa pale ma lalo o ka pale wai wai sodium-bentonite; ma nā wahi ʻē aʻe, ua hoʻonohonoho ʻia kahi geotextile 500g/m² ma ke ʻano he pale pale ma lalo o ka membrane. Hiki ke hoʻohana ʻia kahi ʻāpana o ka pālolo i loko o ka waihona huelo ma ke ʻano he kumu o ka lepo maikaʻi.
ʻO ke ʻano o ka papa anti-seepage ma lalo o ka loko wai huelo penei: nā huelo - sodium bentonite pale pale wai - 300mm lepo maikaʻi - 500g/m² geotextile - papa hoʻoheheʻe wai honua (300mm ʻiliʻili a i ʻole stratum kūlohelohe me ka permeability maikaʻi. , papa hoʻoheheʻe wai ʻauwai makapō) he papa hoʻohalikelike.
ʻO ke kūkulu ʻana o ka papa anti-seepage o ka wai huelo slope (ʻaʻohe wahi e hōʻike ai i ka wai o ka honua): nā huelo - ʻo ka sodium bentonite pale lole pale lole 500g/m² geotextile - pae hoʻohalikelike ʻana.
ʻO ke kūkulu ʻana o ka papa anti-seepage ma luna o ka pali wai huelo (me kahi e ʻike ai i ka wai o ka honua): nā huelo - ka uhi ʻana o ka bentonite me ka sodium - ka papa hoʻoheheʻe wai o ka honua (6.3mm composite geotechnical drainage grid, branched drainage blind awīwī) – pae pae kumu.
