Ngā painga me ngā ngoikoretanga o ngā whatunga waikeri whakakotahi

He rauemi e whakamahia whānuitia ana te whatunga waikeri hiato i roto i ngā kaupapa rori, i ngā whenua ururua, i te whakawhanaketanga o ngā wāhi i raro i te whenua me ētahi atu kaupapa. Nā, he aha ōna painga me ōna ngoikoretanga?

A. Ngā painga matua o te whatunga waikeri hiato

1, mahi pai rawa atu mō te waikeri

Ko te kupenga waikeri whakakotahi he hanganga matua mata toru-ahu (ko te matotoru he 5-8 mm te nuinga), ko te rara poutū o waenganui e hanga ana i tētahi awa waikeri tonu me te tautoko piko, ā, ko te pai o te waikeri he 5-8 ngā wā i te paparanga kirikiri tuku iho. Ka taea e tana pūnaha tiaki pore te tu atu i ngā kawenga teitei (3000 kPa). Ka mau tonu te kawe waipēhi pumau, ā, ka taea e te nekehanga ia wā te eke ki te 0.3 m³/m². He tino pai mō ngā āhuatanga whenua motuhake pēnei i ngā wāhi oneone tio me te maimoatanga turanga ngohengohe.

2, Te kaha teitei me te ātete ki te whakarerekētanga

He mea hanga ki te polyethylene kiato teitei (HDPE) Ko te matua mata kua whakakotahihia ki te muka polypropylene he kaha kume rua-ara o te 20-50 kN/m, Ko te modulus pehitanga he nui ake i te geogrid tuku iho neke atu i te 3 ngā wā. I roto i te ine tuturu o ngā wāhanga waka taumaha, ka whakaitihia te taunga o te papa raro kua whakatakotoria ki te whatunga waikeri hiato mā te 42%, ā, ka whakaitihia te auau o ngā kapiti papa ma te 65%.

3, Hoahoa whakauru maha-mahi

Mā te geotextile (200 g/m²Standard) me te hanganga hiato o te matua mata toru-ahu ka tutuki i te wā kotahi ngā mahi toru o te "tātari-waipuke-whakapakari whakamuri":

（1）Te rahi o te matūriki hopu whai hua o te papanga kore-whatu o runga ＞0.075mm Ngā matūriki oneone o

（2）Ka tere te tuku atu o te matua mata i te wai uruhanga hei ārai i te pikinga o te wai pūwero

（3）Ka whakarei ake ngā rara pakari i te kaha o te turanga, ā, ka whakaiti i te rerekētanga o te papa raro

4, te urutau ki te taiao me te roa

Ko te ātete waikawa me te kawakore o te rauemi kei te pH 1-14, mai i te -70 ℃ ki te 120 ℃. Mā te awhe pāmahana ka mau tonu te mahi. I muri i te 5000 hāora o te whakamātautau koroheketanga tere UV, ka mau te kaha ki te ＞85%, ka roa ake te ora o te rauemi neke atu i te 50 tau.

Ngā herenga tono o te whatunga waikeri hiato

1, ātete poka kore rawaka

Ko te matotoru o te mata o te mata he 5-8 mm te tikanga, he ngāwari te wero i te mata o raro kei roto te kirikiri koi.

2, He iti te kaha ki te horoi wai

I raro i ngā āhuatanga rere wai tere-rahi (tere ≥0.5m/s), Mō ngā totoka i whakatārewatia (SS) Ko te pai o te aukati he 30-40% noa iho, ā, me whakamahi tahi me ngā tāke whakatō, me ngā paparanga tātari rānei i roto i ngā kaupapa maimoatanga paru.

3, Ngā whakaritenga hangarau hanga tino pakari

（1）Me whakahaere te papatahi o te papa turanga ≤15mm/m

（2）Me whai whānui te papa 50-100 mm, Whakamahia he taputapu whakarewa wera motuhake

（3）Me -5 ℃ ki te 40 ℃ te pāmahana o te taiao. Ka taea e te āhuarangi tino kino te arahi ki te whakarerekētanga o te rauemi.

4、Te utu haumitanga tuatahi teitei ake

Ki te whakatauritea ki te paparanga rerenga wai onepū me te kirikiri tuku iho, ka piki ake te utu o ngā rauemi mā te 30% pea, engari ka heke te utu mō te huringa ora katoa mā te 40% (ka whakaitihia te auau tiaki me te tere whakatika turanga).

Taupānga hangarau

1、Kaupapa whakapai ake i te rori ā-tāone

I roto i te hanganga papa uku, mā te whakatakoto i te whatunga rerenga wai hiato i waenga i te paparanga makadam kua whakarōpūtia me te papa raro ka taea te whakapoto i te ara rerenga wai ki te matotoru o te paparanga turanga, ā, ka whakapai ake i te whai huatanga o te rerenga wai.

2, Pūnaha ārai-mimi o te whenua paru

Whakamahia te "whatunga rerenga wai whakakotahi" + te kiriuhi ātete HDPE "hanganga whakakotahi:

（1）Ngā aratohu whatunga rerenga wai, te tauwehenga uruhanga ≤1×10⁻⁴cm/s

（2）Ka whakaratohia e te kiriuhi HDPE matotoru 2mm te parenga ā-rua mō te ārai-mimiti

3、Kaupapa hanga tāone o Sponge

Te whakatakoto i ngā momo oneone e toru-ahu ana i roto i ngā māra ua me ngā wāhi matomato totohu, me te mahi tahi me te PP. Mā te whakamahi i ngā puna wai kōwae ka taea te whakaiti i te tauwehenga rere mai i te 0.6 ki te 0.3, ā, ka māmā ake hoki te noho wai i roto i ngā tāone.
