Liangshan Yi Autonomous Prefecture Landscape Lake Anti-seepage Project

Malo a polojekiti:

Liangshan Yi Autonomous Prefecture, Sichuan, China

Mbiri ya polojekiti:

Dongosolo loyambirira lodana ndi madzi a m'nyanja ya scenic m'malo ochezerako zalephera, zomwe zidapangitsa kuti madzi a m'nyanja atayike kwambiri komanso kusokoneza chilengedwe komanso zochitika za alendo. Ntchitoyi ili kudera lamapiri komwe kumakhala anthu amtundu wa Yi omwe ali ndi zofunikira zoteteza chilengedwe. Ntchito yomangayi iyenera kukhala yopanda kuyipitsa komanso kuwonongeka kwa chilengedwe chozungulira. Kupatula apo, iyenera kugwirizanitsidwa ndi mawonekedwe achilengedwe a malo ochezerako.

Ntchito yothetsera:

Gulu la Zhonglong la geomembrane (HDPE geomembrane + mawonekedwe osawomba a geotextile)

Geomembrane yathu yophatikizika imapangidwa ndi gawo lotsika la polyethylene (HDPE) geomembrane (manenedwe ≥1.5mm) ndi chingwe chapamwamba cha polyester filament non-woven geotextile. HDPE geomembrane imapanga wosanjikiza wodalirika wosalowa madzi ndipo gawo la geotextile limateteza zinthu za geomembrane kuti zisaonongeke ndi zida zobwezeretsanso ndikukulitsa luso la dongosolo lokana kupunduka.

Ntchito yomanga:

Gulu lomanga la Zhonglong nthawi zonse limatsata njira yokhazikika pakuyika kwa geomembrane yophatikizika:

Gawo 1: Yendetsani pansi pa malo omangapo, kuonetsetsa kuti palibe mchenga woonekeratu, miyala, zinthu zakuthwa kapena zinyalala zina.

Gawo 2: Malinga ndi zofunikira zomanga za gulu la geomembrane, ikani mipukutuyo motsatizana ndikusunga mbali zowotcherera (onaninso ngati pamwamba ndi lathyathyathya).

Gawo 3: Tsukani malo owotcherera, ndiyeno werani pang'onopang'ono kudzera pamakina apawiri-track otentha-wedge.

Gawo 4: Yesetsani kuzindikira kuthamanga kwa mpweya, sungani malo a unit kukhala okhazikika mkati mwamtundu wofunikira wa kuthamanga kwa mpweya popanda kutayikira.

Gawo 5: Panthawi yovomerezeka, onetsetsani kuti ntchito zonse zalembedwa dzina la wogwiritsa ntchito, tsiku ndi zina zofunika, ndikutsimikizira kutha kwa ntchitoyo.

Tsatanetsatane wa zomangamanga zotengera momwe zinthu ziliri:

1. Kudera la nyanja ya malo, ntchito yonseyi ilibe zomatira za mankhwala, zomwe zimathetsa ngozi ya kuipitsa madzi.
2. Kwa alendo odzaona malo, pogwiritsa ntchito mankhwala obisika a nangula-ngalandeyo imapewa malo owoneka bwino, odzaza ndi miyala yachilengedwe komanso osakanikirana ndi malo ozungulira.
3. Pakuvomera, mulingo wamadzi m'nyanja uyenera kutsika ≤1mm mkati mwa maola 24, ndipo mawonekedwe amadzi amadzi ayenera kusunga NTU≤5.

Mapeto a polojekiti:

Malinga ndi ndondomekoyi, nyanjayi ikhala ndi madzi okhazikika mchaka chonsecho pamene madzi owonjezera pa chaka adzachepetsedwa ndi matani oposa 100,000, zomwe zidzasintha kwambiri zachilengedwe za nyanjayi.
