Boenjiniere, Marangrang a metsi a kopantsoeng a mahlakore a mararo Ke thepa e sebelisoang haholo, e nang le sebopeho se ikhethang sa sebaka sa mahlakore a mararo le ts'ebetso e ntle haholo ea metsi a metsi.
1. Marangrang a metsi a kopaneng a mahlakore a mararo Melemo ea
1、Ts'ebetso e ntle ea ho ntsha metsi: Letlooa la ho ntsha metsi le nang le mahlakore a mararo le entsoe ka polyethylene e nang le bongata bo phahameng (HDPE) Jwalo ka thepa e tala, le sebetsoa ka mekhoa e ikhethang. Sebopeho sa sebaka sa lona sa mahlakore a mararo se ka fana ka likanale tse ntle tsa ho ntsha metsi, kahoo ts'ebetso ea lona ea ho ntsha metsi e betere haholo ho feta ea thepa ea setso. E na le bokhoni bo matla ba ho ntsha metsi, motlakase o tsitsitseng oa hydraulic o phahameng ka nako e telele, le bokhoni ba ho falla ba li-cubic centimeters tse 20-200 ka motsotso, e leng se ka khutsufatsang nako ea ho ntsha metsi le ho fokotsa kotsi ea ho qoelisoa ka metsing motheong.
2、Bokgoni bo botle ba ho jara mojaro: Letlowa la ho ntsha metsi le kopaneng la mahlakore a mararo ha le na feela tshebetso e ntle ya ho ntsha metsi, empa hape le na le bokgoni bo phahameng haholo ba ho jara mojaro. Sebopeho sa yona sa mantlha sa letlowa se matla mme se ka mamella hoo e ka bang 3000 kPa. Mojaro o hatellang o ka boloka tshebetso e tsitsitseng ya ho ntsha metsi esita le tlasa maemo a boima ba mojaro. Matla a yona a ho tsikinyeha le matla a ho beola le ona a phahame, mme a loketse maemo a fapaneng a rarahaneng a jeoloji.
3、Ho tšoarella hantle le ho hanyetsa boemo ba leholimo: Letlooa la metsi le kopaneng la mahlakore a mararo le entsoe ka polyethylene e nang le bongata bo phahameng le thepa e meng ea boleng bo holimo, e hanelang mafome, e hanelang asiti le alkali, 'me e hanelang ho tsofala, 'me e ka boloka ts'ebetso e tsitsitseng libakeng tse fapaneng tse thata. E na le bophelo bo bolelele ba ts'ebeletso, e ka fokotsa makhetlo a ho nkeloa sebaka le tlhokomelo, le ho fokotsa litšenyehelo tsa boenjiniere.
4、Kaho e bonolo le phokotso ea litšenyehelo: Marang-rang a metsi a kopantsoeng a mahlakore a mararo a sebelisa mokhoa oa thepa e kobehileng, e leng bonolo ho e beha le ho e tsamaisa. E bonolo ho e haha, e ka khutsufatsa nako ea kaho haholo le ho fokotsa litšenyehelo tsa kaho. E na le ts'ebetso e ntle ea metsi a metsi, e ka fokotsang mosebetsi oa kalafo ea motheo le ho fokotsa litšenyehelo tsa boenjiniere.
5、Ts'ebetso e phethahetseng e babatsehang: Marangrang a metsi a kopantsoeng a mahlakore a mararo ha a na mosebetsi oa ho ntša metsi feela, empa hape a na le thepa e felletseng e kang ho thibela ho sefa, ho kenya moea le tšireletso. Likhopo tsa eona tse ka holimo le tse ka tlase tse hlophisitsoeng ka tsela e tšekaletseng li ka thibela geotextile ho kenngoa ka har'a kanale ea ho ntša metsi, 'me li ka boloka phello ea ho ntša metsi ka nako e telele. Lera la eona le phahamisitsoeng le ka boela la arola lera la motheo oa fatše le thepa ea lera le koahelang, e leng se ka fokotsang mathata a kang ho phahama ha metsi a capillary le ho lula ha motheo.
2. Mathata a marang-rang a metsi a kopantsoeng a mahlakore a mararo
1、Bokhoni bo fokolang ba ho thibela ho phunya: Hobane botenya ba letlooa la metsi le kopaneng la mahlakore a mararo bo batla bo le bosesaane, bokhoni ba lona ba ho thibela ho phunya bo fokola. Nakong ea ts'ebetso ea ho beha, hoa hlokahala ho netefatsa hore ha ho na lintho tse bohale tse kholo haholo holim'a bokaholimo ba motheo, e le ho thibela karolo e ka holimo ho phunya geomembrane e thibelang ho sesa le ho ama phello ea ho thibela metsi ka kakaretso.
2、Bokgoni bo fokolang ba ho hlwekisa metsi: Tlas'a maemo a phallo e phahameng, bokgoni ba ho thibela marangrang a metsi a kopaneng a mahlakore a mararo ho ya ho dintho tse emisitsweng boleng ba metsi bo tla fokotseha, e leng se tla lebisa phokotsong ya phello ya ho hlwekisa metsi. Ka hona, moo ho hlokahalang ditlhoko tsa boleng bo hodimo ba metsi, e lokela ho sebediswa mmoho le mehato e meng ya kalafo ya metsi.
3、Litlhoko tse phahameng tsa kaho: Mokhoa oa kaho le litlhoko tsa tekheniki tsa marangrang a metsi a kopantsoeng a mahlakore a mararo li phahame haholo. Ho hlokahala litsebi tsa litsebi ho sebetsa, e le ho netefatsa boleng ba kaho le phello ea metsi. Tlhokomelo e eketsehileng e lokela ho lefshoa lintlha nakong ea ts'ebetso ea kaho, e le ho qoba ho petsoha kapa tšenyo ea letlooa la metsi.
4、Litšenyehelo tse phahameng tsa tlhokomelo: Le hoja marang-rang a metsi a kopantsoeng a mahlakore a mararo a na le bophelo bo bolelele ba tšebeletso, hoa hlokahala ho a hlokomela khafetsa haeba u batla ho netefatsa hore a sebelisoa ka tsela e tloaelehileng. Litšenyehelo tsa tlhokomelo li kenyelletsa litšenyehelo tsa basebetsi, litšenyehelo tsa thepa le litšenyehelo tsa lisebelisoa, tse tla eketsa litšenyehelo tsohle tsa projeke ho isa bohōleng bo itseng.
Ho ka bonoa ho tsoa ho tse boletsoeng ka holimo hore marang-rang a metsi a kopantsoeng a mahlakore a mararo a na le melemo ea ts'ebetso e ntle haholo ea ho ntša metsi, bokhoni bo botle ba ho jara, ho tšoarella hantle le ho hanyetsa boemo ba leholimo, 'me a ka sebelisoa masimong a boenjiniere ba sechaba, boenjiniere ba tikoloho le kaho ea lipalangoang. Leha ho le joalo, mefokolo ea eona e kang bokhoni bo fokolang ba ho thibela ho jara metsi, bokhoni bo fokolang ba ho hloekisa metsi, litlhoko tse phahameng tsa kaho le litšenyehelo tse phahameng tsa tlhokomelo le tsona li hloka tlhokomelo. Tšebelisong e sebetsang, ho hlokahala ho etsa khetho le moralo o utloahalang ho latela litlhoko tse itseng tsa boenjiniere le maemo a tikoloho, e le ho sebelisa melemo ea eona ka botlalo le ho hlola mefokolo ea eona.
