I roto i te hangarau, he mea tino nui te raruraru o te paru. Whatunga waikeri hiato toru-ahu He rauemi waikeri e whakamahia whānuitia ana i roto i ngā kaupapa nui. Nō reira, ka taea e ia te ārai i te paru me te aukati?
1. Auahatanga hanganga
He whatunga waikeri hiato-toru-ahu. He mea hanga te whatunga waikeri hiato-rua-taha me te matua waikeri-toru-ahu. He mea hanga te matua mata ki te polyethylene matotoru (HDPE). Ka hangaia e te tukanga whakahāngai-toru-ahu he whatunga rara whakawhiti-whiti, ā, e whakaatuhia ana tōna ahurei i roto i ngā āhuatanga e rua e whai ake nei:
1, Pūnaha kōhao whakarara: ko te tawhiti o te rara poutū o te matua mata he 10-20 mm, ko te rara whakarara o runga me te rara o raro ka hanga he hongere whakawhiti-ahu-toru, e ōrite ana ki te hoahoa whakarara tuwhera o te geotextile (paparanga o runga 200 μm, taumata o raro 150 μm), te rahi matūriki ka taea te hopu neke atu i te 0.3 mm o te matūriki, Real Now "tātari matawhānui-tātari pai" tātari whakarōpū.
2, Hoahoa ārai-whakauru: te matotoru o te rara matua mata tae atu ki te 4-8 mm, I roto i te 2000 kPa Neke atu i te 90% o te matotoru taketake ka taea tonu te pupuri i raro i te kawenga, kia kore ai e whakauruhia te geotextile ki roto i te mata nā te pēhanga ā-rohe. E ai ki ngā raraunga hangarau o te wāhi ururua whenua, i muri i te 5 tau o te whakamahinga, ka rere te wai i te paparanga waikeri e whakamahi ana i tēnei rauemi. Ko te tere whakaheke he 8% noa iho, he iti iho i te 35% o te paparanga kirikiri tuku iho.
2. Ngā āhuatanga rauemi
1, Te Pūmautanga Matū: HDPE He ātete te matua mata ki te waikura waikawa me te kawakore. I te pH I roto i te taiao waikawa ngoikore me te kawakore ngoikore me te uara o te 4-10, ko tōna tere pupuri pumau hanganga ngota neke atu i te 95%. Polyester whakakotahi Filament geotextile Ka taea e te paninga ātete-UV te ātete ki te koroheketanga o ngā rauemi i puta mai i te hihi UV.
2, Tikanga horoi-ā-koe: te taratara o te mata o te matua mata. Ko te uara Ra e whakahaerehia ana i te 3.2-6.3 μm. I roto i te awhe, ehara i te mea ka taea anake te whakarite i te pai o te rerenga wai, engari ka karo hoki i te piri o te kiriata koiora i puta mai i te maeneene rawa.
3. Te mahi hangarau
1、Te tono para whenua: I roto i te para whenua me te kaha tukatuka o ia rā o te 2,000 tana, ko te whatunga rerenga wai hiato-toru-ahu me te kiriuhi HDPE he pūnaha ārai-mimi hiato. Ka taea e tōna matua mata-toru-ahu te tu atu i te 1500 m³ ia rā. Ko te kawenga pānga o te wai rēreti, me te mahi aukati o te geotextile, ka taea te whakatutuki i te percolation. Ka tukuna te wai ki te taha kotahi, ka taea te aukati i te paru mai i te rere whakamuri. I muri i te 3 tau o te mahi, ko te uara hekenga pehanga o te laminate rerenga wai he 0.05 MPa noa iho, he iti iho i te rohe hoahoa o te 0.2 MPa。
2、Whakamahinga hangarau rori: I roto i te huarahi tere i te rohe oneone tio i te raki o Haina, ka taea te whakamahi hei paparanga rerenga wai whenua, ka taea te whakaiti i te taumata wai whenua mā te 1.2% mā te aukati i te pikinga o te wai kapia m. Ko te pakari taha o tōna matua mata he 120 kN/m. Ka taea e ia te whakawhāiti i te nekehanga o te paparanga turanga konumohe me te whakaiti i te putanga mai o ngā kapiti whakaata. E whakaatu ana te aroturukitanga kua heke te maha o ngā wāhanga rori e whakamahi ana i tēnei hangarau mā te 67% ki te whakaritea ki ngā mate whenua tuku iho, ā, kua roa ake te ora ratonga ki te neke atu i te 20 tau.
3、Te tono hangarau o te kauhanga: I roto i te kauhanga rerewē e haere ana i roto i te paparanga wai-nui, ka whakamahia ngātahitia he whatunga rerenga wai hiato-toru-ahu me te ārai whakapūmau hei hanga i tētahi pūnaha ārai wai o te "whakakotahi i te rerenga wai me te aukati". Ko te kawe wai o tōna matua he 2.5 × 10⁻³m/s，He pai ake te whakapai ake i te pereti rerenga wai tuku iho e 3 ngā wā, me te mahi tahi me te papanga hangarau whenua. Ka taea e te mahi tātari te whakaiti i te tūponotanga o te aukati i te pūnaha rerenga wai o te kauhanga mā te 90%.
4. Rautaki tiaki
1, te aroturuki i te Ipurangi o ngā Mea: Kua whakauruhia ngā pūoko muka whatu ki roto i te whatunga rerenga wai hei aroturuki i ngā tawhā pēnei i te kawe waipēhi, te ahotea me te taumahatanga i te wā tūturu.
2. Te whakamaroke i te wai pēhanga teitei: ngā wāhi kua āraia, whakamahia te wai pēhanga teitei 20-30 MPa mō te keri ahunga. Ka taea e te hanganga rara o te matua mata te tu atu i te pēhanga me te kore e rerekē te āhua, ā, ko te tere whakaora o te kawe waipēhi i muri i te whakamaroke he neke atu i te 95%.
