Letamo la letamo la geomembrane
Tlhaloso e Khutšoanyane:
- Li-geomembrane tse sebelisetsoang matamo a matamo li entsoe ka thepa ea polymer, haholo-holo polyethylene (PE), polyvinyl chloride (PVC), joalo-joalo. Lisebelisoa tsena li na le metsi a fokolang haholo 'me li ka thibela metsi ho kenella ka katleho. Mohlala, polyethylene geomembrane e hlahisoa ka karabelo ea polymerization ea ethylene, 'me sebopeho sa eona sa molek'hule se kopane hoo limolek'hule tsa metsi li sitoang ho feta ho eona.

1.Litšobotsi tsa Ts'ebetso
- Ts'ebetso ea Anti-seepage:
Ena ke ts'ebetso ea bohlokoahali ea li-geomembrane ts'ebetsong ea matamo a matamo. Li-geomembrane tsa boemo bo holimo li ka ba le coefficient ea ho kenella ka hare ho 10⁻¹² - 10⁻¹³ cm/s, hoo e batlang e thibela ka ho feletseng tsela ea metsi. Ha ho bapisoa le lera la setso le khahlanong le seepage, phello ea eona ea anti-seepage e tsoteha haholo. Ka mohlala, tlas'a khatello e tšoanang ea hlooho ea metsi, metsi a phallang ka har'a geomembrane ke karoloana feela ea seo ka letsopa le thibelang metsi. - Ts'ebetso e khahlanong le ho phunya:
Nakong ea ts'ebeliso ea li-geomembrane matamong a polokelo, li ka 'na tsa phunngoa ke lintho tse hlabang tse kang majoe le makala ka har'a 'mele oa letamo. Li-geomembrane tse ntle li na le matla a batlang a le holimo a khahlanong le ho phunya. Ka mohlala, li-geomembrane tse nang le motsoako li na le likarolo tse matlafatsang ka hare tsa fiber tse khonang ho hanela ho phunya. Ka kakaretso, matla a anti-puncture a geomembranes a tšoanelehang a ka fihla ho 300 - 600N, ho netefatsa hore a ke ke a senyeha habonolo tikolohong e rarahaneng ea 'mele oa letamo. - Ho Hanyetsa Botsofali:
Kaha matamo a matamo a na le bophelo bo bolelele ba ts'ebeletso, li-geomembrane li hloka ho ba le khanyetso e ntle ea botsofali. Lisebelisoa tse thibelang botsofali li eketsoa nakong ea tlhahiso ea li-geomembranes, e ba nolofalletsang ho boloka ts'ebetso e tsitsitseng ka nako e telele tlas'a tšusumetso ea maemo a tikoloho a kang mahlaseli a ultraviolet le liphetoho tsa mocheso. Ka mohlala, li-geomembrane tse entsoeng ka mekhoa e khethehileng le mekhoa e ka ba le bophelo ba tšebeletso ea lilemo tse 30 - 50 ka ntle. - Deformation Adaptability:
Letamo le tla ba le mathata a itseng joalo ka ho lula le ho falla nakong ea ts'ebetso ea polokelo ea metsi. Li-geomembrane li ka ikamahanya le li-deformations tse joalo ntle le ho phunyeha. Ka mohlala, li ka otlolla le ho kobeha ho isa bohōleng bo itseng hammoho le ho lula ha 'mele oa letamo. Matla a bona a thata ka kakaretso a ka fihla ho 10 - 30MPa, e ba nolofalletsang ho mamella khatello ea maikutlo e bakoang ke ho senyeha ha 'mele oa letamo.
kness ho ya ka ditlhoko tsa morero. Botenya ba geomembrane hangata ke 0.3mm ho 2.0mm.
- Ho se kenelle ha metsi: Netefatsa hore geomembrane e na le ho se mele hantle ho thibela metsi a mobu ho kena morerong.
2.Lintlha tsa Bohlokoa tsa Kaho
- Kalafo ea Motheo:
Pele o beha li-geomembrane, motheo oa letamo o tlameha ho ba o bataletseng le o tiileng. Lintho tse bohale, mofoka, mobu o hlephileng le majoe holim'a setsi li lokela ho tlosoa. Ka mohlala, phoso ea flatness ea setsi hangata e hlokeha hore e laoloe ka hare ho ± 2cm. Sena se ka thibela geomembrane hore e se ke ea hlajoa le ho netefatsa kamano e ntle pakeng tsa geomembrane le setsi e le hore ts'ebetso ea eona e khahlanong le seepage e ka etsoa. - Mokhoa oa ho beha:
Li-geomembrane hangata li aroloa ka ho tjheseletsa kapa ho kopanya. Ha ho tjheseletsa, hoa hlokahala ho netefatsa hore mocheso oa welding, lebelo le khatello li nepahetse. Mohlala, bakeng sa li-geomembrane tse cheselitsoeng mocheso, mocheso oa tjheseletsa hangata o pakeng tsa 200 - 300 °C, lebelo la tjheseletsa le ka bang 0.2 - 0.5m/min, mme khatello ea welding e pakeng tsa 0.1 - 0.3MPa ho netefatsa boleng ba tjheseletsa le ho thibela. mathata a ho dutla a bakoang ke tjheseletso e mpe. - Pheripheral Connection:
Khokahano ea li-geomembrane le motheo oa letamo, lithaba tse mahlakoreng a mabeli a letamo, joalo-joalo sebakeng sa letamo ho bohlokoa haholo. Ka kakaretso, liforo tse anchoring, capping ea konkreite, joalo-joalo li tla amoheloa. Mohlala, foro e anchore e botebo ba 30 - 50cm e behiloe motheong oa letamo. Moeli oa geomembrane o behoa ka har'a foro ea ankora 'me o tsitsitsoe ka lisebelisoa tsa mobu o momahaneng kapa konkreite ho netefatsa hore geomembrane e hokahane ka thata le mehaho e potolohileng le ho thibela ho tsoa ha peripheral.
3.Tlhokomelo le Tlhahlobo
- Tlhokomelo ea Kamehla:
Hoa hlokahala ho hlahloba kamehla hore na ho na le tšenyo, meokho, li-punctures, joalo-joalo holim'a geomembrane. Ka mohlala, nakong ea ts'ebetso ea letamo, basebetsi ba tlhokomelo ba ka etsa litlhahlobo hang ka khoeli, ba tsepamisitse maikutlo ho lekola geomembrane libakeng tseo boemo ba metsi bo fetohang khafetsa le libaka tse nang le ho holofala ha 'mele oa matamo. - Mekhoa ea ho Hlahloba:
Mekhoa ea tlhahlobo e sa senyeheng e ka amoheloa, joalo ka mokhoa oa tlhahlobo ea spark. Ka mokhoa ona, motlakase o itseng o sebelisoa holim'a geomembrane. Ha ho na le tšenyo ho geomembrane, litlhase li tla hlahisoa, e le hore lintlha tse senyehileng li ka fumaneha kapele. Ntle le moo, ho boetse ho na le mokhoa oa tlhahlobo ea vacuum. Sebaka se koetsoeng se thehoa pakeng tsa geomembrane le sesebelisoa sa tlhahlobo, 'me boteng ba ho lutla ha geomembrane bo ahloloa ka ho shebella phetoho ea tekanyo ea vacuum.
