Boto ea metsi ea polasetiki ea Hongyue
Tlhaloso e Khutšoanyane:
- Boto ea polasetiki ea ho ntša metsi ke thepa ea geosynthetic e sebelisetsoang ho ntša metsi. Hangata e hlaha ka sebopeho se kang sa mola, ka botenya le bophara bo itseng. Bophara hangata bo tloha ho lisenthimithara tse 'maloa ho isa ho tse mashome a lisenthimithara, 'me botenya bo batla bo le bosesaane, hangata bo ka ba limilimithara tse 'maloa. Bolelele ba eona bo ka khaoloa ho latela litlhoko tsa sebele tsa projeke, 'me bolelele bo tloaelehileng bo tloha ho limithara tse 'maloa ho isa ho tse mashome a limithara.

- Sebopeho sa Sebopeho
- Karolo ea Boto ea Motheo: Ena ke sebopeho sa mantlha sa boto ea drainage ea polasetiki. Ho na le libopeho tse peli haholo-holo tsa boto ea mantlha, e 'ngoe ke mofuta oa poleiti e bataletseng, 'me e 'ngoe ke mofuta oa leqhubu. Tsela ea drainage ea boto ea mantlha ea mofuta oa poleiti e bataletseng e otlolohile haholo, ha boto ea mantlha ea mofuta oa leqhubu, ka lebaka la sebopeho sa eona se ikhethang, e eketsa bolelele le ho teteana ha tsela ea drainage 'me e ka fana ka litlamorao tse betere tsa drainage. Thepa ea boto ea mantlha boholo ba eona ke polasetiki, joalo ka polyethylene (PE), polypropylene (PP), jj. Lisebelisoa tsena li na le khanyetso e ntle ea mafome le matla a itseng 'me li ka mamella khatello e itseng ntle le ho fetoha, ho netefatsa hore tsela ea drainage e boreleli.
- Karolo ea Lera la Sefe: E phuthela boto ea mantlha 'me e sebetsa e le sefe. Lera la sefe hangata le entsoe ka geotextile e sa lohiloeng. Boholo ba masoba a eona bo entsoe ka ho khetheha ho lumella metsi ho feta ka bolokolohi ha ka nako e ts'oanang ho thibela likaroloana tsa mobu, lithollo tsa lehlabathe le litšila tse ling ho kena ka har'a tsela ea ho ntša metsi. Mohlala, morerong oa ho ntša metsi oa motheo o bonolo oa mobu, haeba ho se na lera la sefe kapa lera la sefe le hloleha, likaroloana tsa mobu tse kenang ka har'a tsela ea ho ntša metsi li tla etsa hore boto ea ho ntša metsi e koalehe 'me e ame phello ea ho ntša metsi.
- Masimo a Kopo
- Kalafo ea Motheo oa Meaho: Boenjiniereng ba kaho, bakeng sa kalafo ea motheo o bonolo oa mobu, boto ea drainage ea polasetiki ke thepa e sebelisoang haholo. Ka ho kenya liboto tsa drainage motheong, ho kopanngoa ha mobu oa motheo ho ka potlakisoa 'me bokhoni ba ho jara motheo bo ka ntlafatsoa. Mohlala, kahong ea mehaho e phahameng libakeng tse lebopong la leoatle, ka lebaka la boemo bo phahameng ba metsi a ka tlas'a lefatše le mobu o bonolo oa motheo, tšebeliso ea boto ea drainage ea polasetiki e ka ntša metsi a bokellaneng motheong ka katleho, ea khutsufatsa nako ea kaho ea motheo le ho beha motheo o motle bakeng sa botsitso ba moaho.
- Boenjiniere ba Litsela: Kahong ea litsela, haholo-holo kalafong ea subgrade e bonolo ea mobu, boto ea drainage ea polasetiki e bapala karolo ea bohlokoa. E ka fokotsa boemo ba metsi a ka tlas'a lefatše ka potlako ka har'a subgrade le ho fokotsa ho lula le ho fetoha ha subgrade. Mohlala, ts'ebetsong ea kaho ea litsela tse kholo, ho beha liboto tsa drainage tsa polasetiki ka har'a subgrade e bonolo ea mobu ho ka ntlafatsa botsitso ba subgrade le ho ntlafatsa bophelo ba ts'ebeletso ea tsela.
- Ho Hlophisa Naha: Boto ea polasetiki ea ho ntsha metsi e boetse e sebelisoa tsamaisong ea ho ntsha metsi ea meralo ea naha. Mohlala, ho potoloha joang bo boholo, lirapa kapa matša a maiketsetso, tšebeliso ea liboto tsa polasetiki tsa ho ntsha metsi e ka ntša metsi a pula a mangata ka nako, ea thibela litlamorao tse mpe tsa ho bokellana ha metsi kholong ea limela 'me hape ea thusa ho boloka botle le bohloeki ba naha.
- Melemo
- Bokgoni bo Phahameng ba ho ntsha metsi: Sebopeho sa yona se ikgethang sa boto ya mantlha le moralo wa lera la sefe di nolofalletsa metsi ho kena ka potlako tseleng ya ho ntsha metsi le ho ntsha metsi ka thelelo, a na le bokgoni bo hodimo ba ho ntsha metsi ho feta disebediswa tsa setso tsa ho ntsha metsi (tse kang dikoti tsa lehlabathe).
- Kaho e Bonolo: Boto ea polasetiki ea ho ntsha metsi e bobebe ka boima 'me e nyane ka bophahamo, e leng se loketseng lipalangoang le mesebetsi ea kaho. Nakong ea ts'ebetso ea kaho, boto ea ho ntsha metsi e ka kenngoa mobung ka mochini o khethehileng oa ho kenya. Lebelo la kaho le potlakile 'me ha le hloke lisebelisoa tse kholo tsa kaho.
- Litšenyehelo - li sebetsa hantle: Ha li bapisoa le litharollo tse ling tsa ho ntša metsi, litšenyehelo tsa boto ea ho ntša metsi ea polasetiki li tlase haholo. E ka netefatsa phello ea ho ntša metsi ha e ntse e fokotsa litšenyehelo tsa ho ntša metsi tsa projeke, kahoo e sebelisoa haholo mererong e mengata ea boenjiniere.
