Geogrid ya pulasitiki yotambasulidwa mbali imodzi
Kufotokozera Kwachidule:
- Pulasitiki yotambasuka ya geogrid ndi mtundu wa zinthu zopangidwa ndi geosynthetic. Imagwiritsa ntchito ma polima okhala ndi mamolekyulu ambiri (monga polypropylene kapena polyethylene yokhala ndi mamolekyulu ambiri) ngati zinthu zazikulu zopangira ndipo imawonjezeranso anti-ultraviolet, anti-ukalamba ndi zina zowonjezera. Choyamba imatulutsidwa mu mbale yopyapyala, kenako maukonde okhazikika amabowoledwa pa mbale yopyapyala, ndipo pamapeto pake imatambasulidwa motalikira. Panthawi yotambasula, maunyolo a mamolekyu a polima okhala ndi mamolekyulu ambiri amabwerera kuchokera ku mkhalidwe woyambirira wosakhazikika, ndikupanga kapangidwe kofanana ndi kozungulira komwe kali ndi ma node ogawidwa mofanana komanso amphamvu kwambiri.

Makhalidwe Ogwira Ntchito
- Mphamvu Yaikulu ndi Kulimba Kwambiri: Mphamvu yokoka imatha kufika 100 - 200MPa, pafupi ndi mulingo wa chitsulo chotsika cha kaboni. Ili ndi mphamvu yokoka komanso kulimba kwambiri, komwe kumatha kufalitsa bwino ndikusamutsa kupsinjika m'nthaka ndikukweza mphamvu yonyamula ndi kukhazikika kwa nthaka.
- Kukana Kwambiri Kuyenda: Pogwiritsa ntchito mphamvu yopitilira nthawi yayitali, kusintha kwa masinthidwe (kuyendayenda) kumakhala kochepa kwambiri, ndipo mphamvu yolimbana ndi kuyenda kwa mafunde ndi yabwino kwambiri kuposa ya zipangizo zina za geogrid, zomwe zimathandiza kwambiri pakuwonjezera moyo wa ntchito ya polojekitiyi.
- Kukana Kudzimbiritsa ndi Kukana Ukalamba: Chifukwa chogwiritsa ntchito zinthu za polima zokhala ndi mamolekyulu ambiri, zimakhala ndi kukhazikika kwa mankhwala komanso kukana dzimbiri. Zingagwiritsidwe ntchito kwa nthawi yayitali pansi pa nthaka yolimba komanso nyengo zosiyanasiyana popanda kukalamba mosavuta kapena kusokonekera, zomwe zingawonjezere moyo wa ntchito ya polojekitiyi.
- Kapangidwe Kosavuta ndi Mtengo - magwiridwe antchito: Ndi kopepuka - kulemera, kosavuta kunyamula, kudula ndi kuyika, ndipo kumakhala ndi zotsatira zabwino zomangira, zomwe zimachepetsa ndalama zomangira. Nthawi yomweyo, imakhala ndi magwiridwe antchito abwino ogwirizana ndi dothi kapena zipangizo zina zomangira ndipo ndi yosavuta kuphatikiza ndi nyumba zosiyanasiyana zaukadaulo wa zomangamanga kuti ipititse patsogolo magwiridwe antchito onse komanso kukhazikika kwa polojekitiyi.
- Kulimbana ndi Chivomerezi Chabwino: Kapangidwe kolimba kosunga nthaka ndi kapangidwe kosinthasintha komwe kangathe kusintha pang'ono maziko ake ndikuyamwa bwino mphamvu ya chivomerezi. Kali ndi magwiridwe antchito a chivomerezi omwe nyumba zolimba sizingagwirizane nawo.
Madera Ogwiritsira Ntchito
- Kulimbitsa Pansi pa Madzi: Kumatha kukweza mphamvu ya maziko ndikuwongolera chitukuko cha malo okhala. Kumalepheretsa mbali ya msewu, kumagawa katundu ku sub-base yayikulu, kumachepetsa makulidwe a maziko, kuchepetsa ndalama zomwe zimagwiritsidwa ntchito komanso kukulitsa nthawi yogwira ntchito ya msewu.
- Kulimbitsa Misewu: Poyikidwa pansi pa phula kapena simenti, imatha kuchepetsa kuya kwa phula, kukulitsa nthawi yolimbana ndi kutopa kwa phula, komanso kuchepetsa makulidwe a phula kapena simenti, kukwaniritsa cholinga chopulumutsa ndalama.
- Kulimbitsa Damu ndi Makoma Osungira Madzi: Ingagwiritsidwe ntchito kulimbitsa malo otsetsereka a makoma ndi makoma osungira madzi, kuchepetsa kuchuluka kwa kudzaza madzi panthawi yodzaza makoma, kupangitsa kuti m'mphepete mwa phewa mukhale kosavuta kukumba, kuchepetsa chiopsezo cha kugwa kwa makoma ndi kusakhazikika kwa madzi pambuyo pake, kuchepetsa malo okhala, kukulitsa nthawi yogwirira ntchito ndikuchepetsa mtengo.
- Chitetezo cha Mitsinje ndi Nyanja: Chikapangidwa kukhala ma gabions ndikugwiritsidwa ntchito limodzi ndi geogrids, chingalepheretse kuti gombelo lisasunthidwe ndi madzi a m'nyanja ndikupangitsa kugwa. Kulowa kwa ma gabions kumatha kuchepetsa mphamvu ya mafunde ndikuwonjezera moyo wa gombelo, kupulumutsa anthu ndi zinthu zina ndikufupikitsa nthawi yomanga.
- Kukonza Zotayira: Kugwiritsidwa ntchito limodzi ndi zinthu zina zopangira dothi.
