Ko te Geosynthetics he kupu whanui mo nga rawa waihanga e whakamahia ana i roto i nga mahi miihini a-iwi. Hei rauemi hangahanga tangata, ka whakamahia nga polymers waihanga (pēnei i te kirihou, te muka matū, te rapa waihanga, me etahi atu) hei rauemi mata hei hanga momo momo hua, ka tuu ki roto i te oneone, ki te mata, ki waenga ranei i nga momo oneone. , ki te takaro i te mahi o te parewai me te aukati, te whakakaha, te whakaheke wai me te tātari me te whakaora rauropi.
Tirohanga mo te harotoroto hiku
1. Waiwai
He harotoroto hiku maina parahi kei roto i te riu. He hiwi kei te raki, te hauauru me te taha tonga kua wehea mai i te puna wai huri noa. Ko te harotoroto hiku he 5km² te rohe hopu. He wai kei roto i te rua i te tau katoa, he nui te rere o te wai.
2. Topography
Ko te nuinga o te wa ko te raorao te raki-ma-tonga-ma-tonga, ka huri ki te raki-ma-raki ki te wahanga Mizokou. He ahua tuwhera te riu, he 100m pea te whanui me te 6km te roa. Kei waenganui o te riu te papuni tuatahi o te harotoroto hiku e whakaarohia ana. He pari te ahua o te tahataha o te tahataha, a, ko te nuinga o te 25-35° te titahatanga, he ahua whenua o te pae maunga tectonic denudation.
3. Hangaia nga tikanga whenua
I te wa e hoahoa ana i te mahere aukati mo te harotoroto hiku, me mahi tuatahi te rangahau arowhenua o te waahi puna. Kua whakahaeretia e te wae hangahanga te rangahau a-whenua o te harotoroto himori: karekau he koha kaha e puta i roto i te waahi puna; Te oneone pakeke, ko te waahanga hangahanga ko te Class II; ko te wai o te whenua kei roto i te waahi puna ko te nuinga o nga wai kawa i te toka; he mau tonu te paparanga toka, a, he matotonu te rohe huarere kaha kua tohatohahia ki te waahi o te papuni, me te kaha miihini teitei. Ka tino whakatauhia he waahi pumau te waahi whakaurunga hiku, a, he pai mo te hanga whare putunga.
Te kaupapa aukati i te harotoroto o te harotoroto hiku
1. Te kowhiringa o nga rauemi aukati
I tenei wa, ko nga mea hangai-a-tinana e whakamahia ana i roto i te kaupapa ko te geomembrane, te paraikete parewai konutai bentonite, me etahi atu. whakatakotoria ki te konutai bentonite paraikete parewai Te koretake whakapae.
2. He puna wai o raro te puna wai o raro
I muri i te horoinga me te maimoatanga o te raro o te puna, ka whakatakotoria he papa kirikiri 300mm te matotoru ki raro o te puna hei paparanga wai o te whenua, ka whakanohohia he awaawa matapo mo te rerenga wai ki raro o te puna, me te putorino DN500. ka whakatakotoria ki roto i te rua matapo hei arataki nui mo te whakaheke wai. Ka whakatakotohia nga awaawa matapo mo te wairere arataki ki te taha o te taha o raro o te harotoroto hiku. E 3 nga awaawa matapo i te katoa, ka whakaritea ki te taha maui, waenganui me te taha matau i roto i te harotoroto.
3. Te punaha whakaheke wai o raro
I roto i te waahi rewharewha o te wai o raro, ka whakatakotoria he kupenga waiariki hiato, ka whakatakotohia nga awaawa matapo me nga paipa manga wairere ki ia manga i roto i te waahi puna, e hono ana ki te paipa matua kei raro o te puna.
4. Whakatakoto rauemi Anti-seepage
Ko nga mea whakapae i roto i te waahi puna wai hiku ka tango i te paraikete parewai bentonite-konutai. Kei raro o te harotoroto hiku ka whakatakotoria he paparanga wai kirikiri o raro. I runga i te whakaaro ki te whakamarumaru i te paraikete parewai konutai bentonite, ka whakatakotoria he oneone 300mm te matotoru ki runga i te paparanga kirikiri hei papa whakamarumaru i raro i te kiriuhi. I runga i te titahatanga, ka whakatakotoria he kupenga waihanga matawhenua hiato ki etahi waahi hei paparanga whakamarumaru i raro i te paraikete parewai konutai-bentonite; i etahi atu waahi, ka whakaritea he geotextile 500g/m² hei paparanga whakamarumaru i raro i te kiriuhi. Ka taea te whakamahi i tetahi wahanga o te paru paru i roto i te puna wai hiku hei puna mo te oneone pai.
Ko te hanganga o te paparanga aukati i te raro o te harotoroto hiku e whai ake nei: hiku – konutai bentonite paraikete parewai – 300mm oneone pai – 500g/m² geotextile – paparanga wai o te whenua (300mm papa kirikiri, papa taiao ranei he pai te uruhanga. , paparanga waikeri Ko te awaawa matapo) he paparanga turanga paparite.
Te hanganga o te paparanga parepare o te tahataha harotoroto (karekau he waahi e kitea ana i te wai o raro): nga hiku – konutai bentonite wheketere paraikete parewai 500g/m² geotextile – paparanga turanga.
Te hanganga o te paparanga parepare i runga i te tahataha harotoroto (me te waahi e kitea ana te wai o te whenua): nga hiku – paraikete parewai bentonite na runga konutai – paparanga wai o raro (6.3mm te matiti waihanga matawhenua hiato, te awaawa matapo whakamaarama) – paparanga turanga.
