Haeba u rakonteraka kapa moenjiniere ea sebetsang mererong ea kotopo, metro, kapa ea ka tlas'a lefatše kae kapa kae lefatšeng, ua tseba hore na ho thibela metsi ho tšepahala ho bohlokoa hakae—le hore na ho ka ja nako e kae sebakeng seo. Shandong Hongyue Environmental Protection Engineering Co., Ltd. e mona ho fetola seo ka Tunnel ea rona e inehetseng ho eonaBoto e sa keneleng metsi ea Eva, e etselitsoe ho nolofatsa mosebetsi oa hau le ho etsa hore merero ea hau e sebetse hantle haholoanyane.
Ena ha se thepa e 'ngoe feela e thibelang metsi. Moralo oa rona oa mofuta oa ho leketlisa o felisa tlhoko ea ho lokisa lintho tse kenang ka mokhoa o litšila le o jang nako. Ho e-na le hoo, boto e tla le marapo a hahiloeng ka hare a u lumellang ho e kenya ka mohato o le mong o boreleli, e fokotsa nako ea basebetsi ka ho fihlela ho 30% le ho qeta projeke ea hau kapele. Ebang u sebetsa kotopong ea terene India, mola oa metro Asia Boroa-bochabela, kapa tsela e kholo e ka tlas'a lefatše Afrika, sistimi ena e ikamahanya le litlhoko tsa sebaka sa hau sa marang-rang.
Kgetha pakeng tsa dikgetho tse pedi tse sebetsang: mofuta o arohaneng o o dumella ho beha dikarolo tsa geotextile le geomembrane ka boikemelo, ha mofuta wa rona o kopaneng o kopanya 300–400g/m² polyester geotextile le geomembrane ya EVA/PE/ECB hantle fekthering. Ka bophara bo ka fetolwang (2–4m), botenya (0.8–2.0mm), le bolelele bo etseditsweng projeke ya hao, o fumana ho lekana hantle nako le nako.
Li tšehelitsoe ke maemo a thata a China a GB18173.1-2012, liboto tsa rona li fana ka matla a ho thaepa a ≥16 MPa, bolelele ba ≥550%, le botsitso esita le ho 60°C—kahoo ua tseba hore li tla tšoarella, ho sa tsotelehe maemo. Re romela thepa lefatšeng ka bophara ho tsoa Koung ea Qingdao, re netefatsa hore thepa ea hau e fihla ka nako, kae kapa kae moo projeke ea hau e leng teng.
“Ho Shandong Hongyue, re haha ditharollo tse rarollang mathata a nnete,” ho boletse sebui sa khamphani. “Re motlotlo ho fa bahahi lefatshe ka bophara sistimi ya ho thibela metsi e bolokang nako, e fokotsang ditjeo, le ho fana ka diphetho tse tshwarellang nako e telele.”
