Ngā Whakaaro Matua mō ngā Geotextiles

I te mea kei te uru atu te hanganga hanganga ki tētahi wāhanga o te whanaketanga kounga teitei, kei te whānui haere te whakamahinga o ngā rauemi geosynthetic i roto i ngā mara pēnei i ngā huarahi tere, te tiaki wai, me te tiaki taiao. Hei tauira i roto i te umanga, i whakamahia e Shandong Hongyue Environmental Engineering Co., Ltd. (e kiia nei ko "Hongyue Environmental") ōna tau o te wheako ratonga me ngā rangahau take o te ao tūturu hei whakaputa i ngā whakaaro matua e toru e pā ana ki te kōwhiringa me te tāutanga o ngā geotextiles. E kī ana ngā tohunga ko te whāinga o tēnei kaupapa he āwhina i ngā kaipupuri kaupapa ki te karo i ngā hapa kounga noa, kia kore ai e puta ngā tūponotanga haumaru me ngā mate ōhanga e puta mai ana i te kōwhiringa rauemi hē.
Te Mahanga #1: Te Whakaiti Matapōkere i ngā Utu me te Whakakore i te Whakataurite Whakatakotoranga
I roto i te ao o ngā hanganga kawe waka, ko ētahi kaupapa—hei penapena i te tahua—ka whiriwhiri i ngā kākahu whenua iti iho te kounga; he tūponotanga nui tēnei ki te kounga o te kaupapa whānui. I roto i ngā rangahau i te mara, i kitea e te tīma hangarau o Hongyue Environmental kua whakamahia e ētahi kaupapa huarahi ngā kākahu whenua polypropylene he iti iho i te 100 karamu/m² te taumaha mō te hanganga paparanga turanga. Ko te kaha kume o aua rauemi he iti iho i te 8 kN/m; nō reira, he tino ngawari ki te werohia e te kōhatu pakaru i te wā e whakakīia ana e ngā mīhini taumaha, tae noa ki te haehae nā te iti o te taunga o te turanga i muri i te whakatuwheratanga o te huarahi ki te waka—ka arahi tika ki te hanganga o ngā kapiti i te mata o te papa.
Ko tētahi take nui ko tētahi kaupapa huarahi i te Porowini o Shandong, nā te whakamahinga o ngā kākahu whenua iti iho i te paerewa, ka tīmata te heke o te papa rori i roto i ngā marama e toru i muri i te whakatuwheratanga. I te mutunga, i hiahiatia he mahi anō utu nui—neke atu i te 200,000 RMB—nā tēnei i tino whakararuraru i ngā mahi kawe waka me ngā mahi kawe waka ā-rohe. Hei tāpiri, ki te kore ngā kākahu whenua i hangaia mō ngā papa rori rerewē i tukinotia ki te maimoatanga ārai-pakeke, ka heke pea tō rātou kaha neke atu i te 30% mēnā ka waiho kia pāngia e ngā āhuatanga o te rangi mō ngā marama e toru, ā, ka mākū i te wai ua.
I runga i tēnei, ka tukuna e Hongyue Environmental te taunakitanga e whai ake nei: me piri pūmau te kōwhiringa rauemi mō ngā kaupapa hangarau ki te kaupapa o te "taurite i ngā whakaritenga." Mō ngā wāhanga hanganga nui—pērā i te whakakaha o te papa rori—me tīpako ngā geotextile miro polyester kaha-teitei, ngā geotextile muka tūāpapa kounga teitei rānei. Hei tāpiri, me whakahaere te whakamātautau pakari o ngā tohu mahi matua—pērā i te kaha pakaru me te kaha haehae—i runga i te tutuki pūmau ki ngā paerewa ā-motu (hei tauira, GB/T 17638-2017); kaua rawa te utu hei whakatau anake mō te kōwhiringa rauemi.
Te Mahanga #2: Te Kore e Rawa te Ātete ki te Waikura me te Ātete ki te Waikura—Ngā Mōrearea Huna i roto i ngā Kaupapa Tiaki Wai
Ki te whakaritea ki te hanga rori, he nui ake ngā whakaritenga pakari a ngā kaupapa tiaki wai mō te ātete ki te waikura me te ātete ki te waikura o ngā rauemi hanga. I a rātou e whakarato ana i ngā ratonga mō ngā raina peka o te Kaupapa Whakawhiti Wai mai i te Tonga ki te Raki, i kitea e Hongyue Environmental Protection he maha ngā geotextile i hangaia e ngā kaihanga iti i pāngia e ngā hapa nui - pērā i te hiri koretake i ngā hononga me te whānui taupatupatu iti iho i te 10 cm - nā reira i tino ngawari ai te turuturu. He mea whakamataku ake, i roto i ngā kaupapa whakaora whenua tote-kawa, i ētahi wā ka he te whiriwhiri i ngā geotextile polypropylene noa - kāore e ātete ki ngā waikawa me ngā kawakore. Nā tēnei i koroheke ai, i pirau ai ngā rauemi i roto i ngā marama e ono noa iho, ā, ka kore rawa e pai te mahi ārai-turuki.
"Ko te ngoikore o te ātete ki te turuturu me te waikura ka puta he tūponotanga huna i roto i ngā pareparenga." E whakanui ana a Hongyue Environmental Protection, mō ngā kaupapa hangarau waipēhi—pērā i ngā tāhuna me te whakaora i ngā awaawa—he mea nui kia whiriwhiria ngā geotextile hiato, ngā geomembrane HDPE rānei he ātete matū pai ake, he ātete poka hoki. Ka whakamahia e ā rātou hua ngā tukanga here wera, ngā tukanga whakapiripiri rānei hei whakarite i tētahi hononga piripono, kore e taea te wehe i waenga i te geotextile me te kiriuhi ārai wai, kia tū pakari ai te horo i roto i ngā taiao uaua. Hei tāpiri, ka whakamatautauria ia puranga hua ki te pēhanga waipū pakari hei whakarite i te pono tino.
Whakaaro Hē #3: Te Whakawā Hē i te Āheinga o te Hau—He uaua ki ngā tipu te ora i runga i ngā pari matomato
I roto i ngā kaupapa whakaora keri me te whakatōtika i ngā pari, he mea nui anō hoki te hototahitanga ā-taiao o ngā rauemi e whakamahia ana. He maha ngā tīma hanga e hē ana ki te whakakapi i ngā "geomembranes ātete-wai" mō ngā "geotextiles uru-wai." Mā tēnei ka ārai i te mimiti o te makuku o te oneone, ka pāngia ngā pakiaka tipu e te korenga o te hāora me te maroke, ka hua ake he tino iti te ora. Hei tauira, i roto i tētahi kaupapa whakaora keri o mua, i kitea te hekenga o te ora o ngā purapura tarutaru ki raro iho i te 30% nā tēnei hapa; i whakatauhia te take i muri i te huri ki ngā geotextiles polyester uru-hau.
Hei whakatika i tēnei take, e tohu ana a Hongyue Environmental Protection, mō ngā mahi whakatō kākano pari, me aro nui ki ngā kākahu whenua kore-whatu kua werohia ki te ngira, he mea e tuku ana i te uruhanga wai pai rawa atu me te kaha ki te keri. Ehara i te mea ka āwhina noa tēnei rauemi i te rerenga wai, ā, ka mahi hei tātari whakamuri engari ka ārai hoki i te horo o te oneone, ā, ka hangaia he taiao moroiti pai mō te tipu o ngā tipu. Ina whakamahia ngātahi me ngā whakatikatika oneone, ka taea te whakanui ake i te tere oranga o ngā tipu ki te neke atu i te 85%, ka whakarite kia whakaaetia angitu i te wā o te tirotiro whakamutunga o te kaupapa whakaora taiao.
Te Mana Kounga Whānui me te Ratonga: Te Whakatakoto Paerewa Ahumahi Hou
Hei whakapūmau i te kounga o te hua, kua whakatūria e Hongyue Environmental Protection tētahi pūnaha tirotiro taumata-toru e kapi ana i te tukanga katoa: mai i ngā rauemi mata ki te hanga, ā, i te mutunga ki te hua kua oti. Ka whakamahia e te kamupene ngā maramara polyester kounga teitei hei rauemi mata, ā, ka whakatūhia he tirotiro kounga pakari i ngā wāhanga nui—pēnei i te wero ngira me te whakapiripiri—hei whakarite i te pono o te hua. Hei tāpiri, ka tono te kamupene i ngā tari tuatoru whai mana ki te whakahaere whakamātautau motuhake, kia whakapūmau ai ko ia rōra geotextile e puta atu ana i te whare e tutuki katoa ana i ngā paerewa ā-motu.
Haunga te whakarato i te kounga hua tino pai, ka tukuna e Hongyue Environmental tētahi kete ratonga whānui, kotahi-mutunga e whakauru ana i te kōrero hangarau, te hoahoa otinga, te aratohu hanga, me te tiaki i muri i te hoko. Ahakoa e whakamahia ana ki ngā kaupapa hanganga ā-rohe nui, e whakamahia ana rānei i te wā e whānui ana te kamupene ki ngā mākete o te ao, kua whiwhi tēnei tauira ratonga mai i te pito ki te pito i te whakamoemiti me te mōhiotanga nui mai i ngā kiritaki. I te heke mai, ka mau tonu a Hongyue Environmental i tana rapunga whakaaro matua—"E Pumau ana i te Kounga, e Aratakina ana e te Ratonga"—nā te mea he tūranga nui tāna ki te tiaki me te tautoko i te whanaketanga hanganga o Haina.
