Mena he kaimahi kirimana, he miihini rānei koe e mahi ana i ngā kaupapa kauhanga raro whenua, kauhanga raro whenua, kauhanga raro whenua rānei i te ao katoa, e mōhio ana koe ki te hiranga o te ārai wai pono—me te roa o te wā e pau ana i te papa mahi. Kei konei a Shandong Hongyue Environmental Protection Engineering Co., Ltd. hei whakarerekē i tēnā me tā mātou Tunnel DedicatedPapa Ārai Wai EVA, i hangaia hei whakangāwari ake i tāu mahi, hei whai hua ake hoki i ō kaupapa.
Ehara tēnei i te mea he rauemi ārai wai noa iho. Nā te hoahoa whakairi, kāore e hiahiatia he whakapiringa paru, he roa hoki te wā e pau ana. Engari, kei roto i te papa he whitiki kua hangaia hei whakauru i roto i te kotahi taahiraa maeneene, ka whakaiti i te wā mahi tae atu ki te 30%, ā, ka tere ake te whakaoti i tō kaupapa. Ahakoa kei te mahi koe i tētahi kauhanga rerewē i Īnia, i tētahi ara tereina i te Tonga-mā-rāwhiti o Āhia, i tētahi ara raro rānei i Āwherika, ka urutau tēnei pūnaha ki ngā hiahia o tō papa.
Kōwhiria i waenga i ngā kōwhiringa mahi e rua: mā te momo wehe ka taea e koe te whakatakoto motuhake i ngā paparanga geotextile me te geomembrane, ko tā mātou putanga hiato ka honoa te geotextile polyester 300–400g/m² ki te geomembrane EVA/PE/ECB i te wheketere tonu. Me ngā whānui ka taea te whakarite (2–4m), ngā matotoru (0.8–2.0mm), me ngā roa e rite ana ki tō kaupapa, ka whiwhi koe i te taunga tino pai i ngā wā katoa.
I tautokona e te paerewa pakari GB18173.1-2012 a Haina, ka tukuna e ā mātou papa he kaha kume ≥16 MPa, he roa ≥550%, ā, he pumau ahakoa i te 60°C—nō reira ka mōhio koe ka mau tonu, ahakoa ngā āhuatanga. Ka tukuna e mātou he kaipuke puta noa i te ao mai i te Tauranga o Qingdao, kia whakarite kia tae mai ō rauemi i te wā tika, ahakoa kei hea tō kaupapa.
"I Shandong Hongyue, ka hangaia e mātou ngā otinga e whakaoti rapanga tūturu ana," te kī a te kaikorero a te kamupene. "E whakahīhī ana mātou ki te hoatu ki ngā kaihanga o te ao katoa he pūnaha ārai wai e penapena ana i te wā, e whakaiti ana i ngā utu, ā, e whakaputa ana i ngā hua roa."
