Pulasitiki Yotambasulidwa Yozungulira Mbali Ziwiri
Kufotokozera Kwachidule:
Ndi chinthu chatsopano chopangidwa ndi geosynthetic. Chimagwiritsa ntchito ma polima okhala ndi mamolekyulu ambiri monga polypropylene (PP) kapena polyethylene (PE) ngati zinthu zopangira. Ma mbalewo amapangidwa koyamba kudzera mu pulasitiki ndi extrusion, kenako amabowoledwa, ndipo pamapeto pake amatambasulidwa motalikira komanso mopingasa. Panthawi yopanga, maunyolo okhala ndi mamolekyulu ambiri a polima amakonzedwanso ndikuwongoleredwa pamene zinthuzo zikutenthedwa ndi kutambasulidwa. Izi zimalimbitsa kulumikizana pakati pa maunyolo okhala ndi mamolekyulu motero zimawonjezera mphamvu zake. Kuchuluka kwa kutalika ndi 10% - 15% yokha ya mbale yoyambirira.

Ubwino wa Kuchita Bwino
Mphamvu Yaikulu: Kupyolera mu njira yapadera yotambasula, kupsinjika kumagawidwa mofanana mbali zonse ziwiri zakutali komanso zopingasa. Mphamvu yokoka ndi yayikulu kwambiri kuposa ya zipangizo zachikhalidwe za geotechnical ndipo imatha kupirira mphamvu zazikulu zakunja ndi katundu.
Kugwira Ntchito Bwino: Imatha kusintha malinga ndi kukhazikika ndi kusinthika kwa maziko osiyanasiyana ndipo imasonyeza kusinthasintha kwabwino m'malo osiyanasiyana aukadaulo.
Kulimba KwabwinoZipangizo za polima zokhala ndi mamolekyulu ambiri zomwe zimagwiritsidwa ntchito zimakhala ndi kukana dzimbiri kwa mankhwala komanso kukana kuwala kwa ultraviolet ndipo sizimawonongeka mosavuta zikagwiritsidwa ntchito kwa nthawi yayitali m'malo ovuta.
Kugwirizana Kwambiri ndi Dothi: Kapangidwe kofanana ndi ukonde kamawonjezera mphamvu yolumikizana ndi yoletsa ya ma aggregates ndipo kamawonjezera kwambiri mphamvu ya kukangana ndi nthaka, zomwe zimathandiza kupewa kusamuka ndi kusintha kwa nthaka.
Madera Ogwiritsira Ntchito
Uinjiniya wa Misewu: Imagwiritsidwa ntchito polimbitsa mphamvu ya subgrade m'misewu ikuluikulu ndi njanji. Ikhoza kuwonjezera mphamvu ya bearing ya subgrade, kutalikitsa moyo wa ntchito ya subgrade, kupewa kugwa kwa msewu kapena ming'alu, komanso kuchepetsa kusakhazikika kwa malo.
Uinjiniya wa Madamu: Zingathandize kuti madamu akhale olimba komanso kupewa mavuto monga kutayikira kwa madzi m'madamu ndi kugwa kwa nthaka.
Chitetezo cha Potsetsereka: Zimathandiza kulimbitsa malo otsetsereka, kupewa kukokoloka kwa nthaka, komanso kukonza malo otsetsereka. Nthawi yomweyo, zimatha kuthandizira udzu wotsetsereka - kubzala mphasa ya ukonde komanso kuchita gawo lokongoletsa chilengedwe.
Malo Akuluakulu: Ndi yoyenera kulimbitsa maziko a malo akuluakulu onyamula katundu monga ma eyapoti akuluakulu, malo oimika magalimoto, ndi malo osungira katundu padoko, zomwe zimapangitsa kuti mazikowo akhale olimba komanso kuti azikhala olimba.
Kulimbitsa Khoma la Ngalande: Amagwiritsidwa ntchito kulimbitsa makoma a ngalande mu uinjiniya wa ngalande ndikuwonjezera kukhazikika kwa makoma a ngalande.
