Yunnan Mountainous Area Irrigation Canal Seepage Prevention Project

Malo a polojekiti: Yunnan, China

Mbiri ya polojekiti:

Madera akumapiri a Yunnan ndi ovuta, chifukwa chake ndizovuta kugwiritsa ntchito njira zachikhalidwe zopewera konkriti pazovuta zomanga komanso nthawi yayitali yokonza.

Kwenikweni, ngalande yadothi yomwe ilipo m'dera lothirirali ili ndi madzi ambiri. Kugwiritsa ntchito madzi sikufika pa 60%, ndipo pali chiopsezo cha kugwa m'madera ena otsetsereka chifukwa cha kukokoloka kwa madzi a mvula. Chifukwa chake, njira yolimbikitsira yofulumira, yosinthika ndiyofunikira.

Ntchito yothetsera: Simenti Mat Anti-seepage System (GCCM)

Kugwira ntchito, kumatanthauzidwa ngati konkire yosinthika yosinthika yosinthika. Amapangidwira kuti asatseke madzi ndikugwiritsa ntchito zotsutsana ndi njira zosiyanasiyana, hydration yake yofulumira komanso yokhazikika ikuyendetsa kukhazikitsidwa kwake kwapadziko lonse ngati njira yabwino kwambiri yopangira konkriti yoponyedwa m'malo opangira ma hydraulic.

Ntchito yomanga:

Ntchitoyi ili m'dera lamapiri ku Yunnan lomwe lili pamtunda wa 2,200m, kutalika kwa njirayo ndi pafupifupi 530m yokhala ndi mapiri otsetsereka komanso mapindika akuthwa. Sizingatheke kuti makina akuluakulu alowe ndikugwira ntchito. Gulu la zomangamanga limagwira ntchito molingana ndi mtunda ndi mawonekedwe a hydrological:

Gawo 1. Kusintha

Kusintha nthaka ndi sitepe yoyamba komanso yofunika. Nthaka iyenera kupirira kukakamizidwa kuti zitsimikizire kulimba kwa mphasa ya simenti.

• Sinthani mawonekedwe apansi kuti apange zinthu zosiyanasiyana, monga maiwe, ngalande zamadzi, ndi zina.
• Malo otsetsereka asapitirire madigiri 45 (kutengera momwe nthaka ilili)
• Gwirizanitsani nthaka kuti ikhale yolimba (nthaka iyenera kukhala yokhazikika)
• Pangani pamwamba pamtunda, zomwe zimatsimikizira kukongola kwa mankhwala omalizidwa

Gawo 2. Grooving

• Fukula ngalande yoyika mphasa wa simenti ndi mtunda kuchokera ku ngalande kupita kumalo osanjikiza kumbuyo osachepera 50cm. M'lifupi mwa ngalandeyo ndi pafupifupi 30cm, ndipo kuya kwake kuli 50cm. Kenako ikani mphasa ya simenti ndikuikonza ndi misomali yokonzekera yooneka ngati "U". pa 1m.
• Makasi a simenti ayenera kuikidwa molimba m'malo okonzedwa ndipo ayenera kuikidwa kuchokera pamwamba mpaka pansi.
• Poyalidwa, m'mphepete mwa chidutswa chilichonse chiyenera kupindika, ndipo m'mphepete mwa mphasa ya simenti iyenera kupindika. Chigawo chophatikizika sikuyenera kupitirira 10 cm.
• Kenako timasakaniza zomatira za simenti, matope kapena zinthu zomangika ndi madzi ndikuyambitsa kusakanikirana koyenera ngati zomatira pakati pa zidutswazo.

Gawo 3. Kukonza

• Chidutswa chilichonse cha mphasa ya simenti chiyenera kukhazikika ndi misomali osachepera mainchesi 5 m'litali*, yomwe iyenera kukhazikitsidwa pambali pa msoko pafupifupi 30cm, ndi misomali osachepera 5 cm kutali kuchokera m'mphepete mwa mphasa ya simenti.
• Kukonzekera kwa mphasa ya simenti kuzinthu zoyambira kapena pamwamba kuyenera kuchitidwa pogwiritsa ntchito misomali yokhazikika yooneka ngati "U". m'litali osachepera 30 cm*, yokhazikika pambali pa msoko pa 1m.

Gawo 4. Kuthirira

• Thirirani mphasa ya simenti mofanana (osachepera 5 malita/m²).
• Kuti zomalizidwazo zikhale zolimba, madzi ayenera kuthiridwa kamodzi pa tsiku kwa masiku atatu.

Mapeto a polojekiti:

Ntchito yonseyi idamalizidwa m'masiku a 3, omwe anali ndi chiwonjezeko cha 70% poyerekeza ndi zomangamanga zachikhalidwe pamalopo. Pogwira ntchito, kusanjikiza kwatsopano kwa tchanelo kumapitilira komanso kopanda msoko, zomwe zimapangitsa kuti madzi azigwiritsa ntchito bwino mpaka 90%. Moyo wautumiki womwe ukuyembekezeka ndi wopitilira zaka 10.

Lumikizanani nafe kuti mulandire!
