Kodi mungamangire bwanji ma geogrid m'misewu yayikulu komanso misewu yama eyapoti?

Pakadali pano, pali mitundu iwiri ya ma geogrids omwe amagwiritsidwa ntchito kwambiri: okhala ndi zomatira komanso opanda zomatira.Omwe ali ndi zomatira zodzimatira amatha kuyikidwa mwachindunji pagawo losanjikiza, pomwe omwe alibe zomatira zokha nthawi zambiri amakhala ndi misomali.

Malo omanga:

Zimafunika kuphatikizika, kusanja, ndi kuchotsa zotuluka zakuthwa.Kuyika kwa gridi;Pamalo athyathyathya komanso ophatikizika, njira yayikulu yolimbikitsira (longitudinal) ya gridi yomwe idayikidwa ndi yoyala iyenera kukhala yolunjika komwe kumalowera.Kuyikako kuyenera kukhala kosalala, kopanda makwinya, ndipo kuyenera kukhala kokhazikika momwe mungathere.Kukhazikika ndi ma dowels ndi nthaka ndi miyala ya ballast, njira yayikulu yolimbikitsira gululi iyenera kukhala yotalikirapo popanda mfundo, ndipo kulumikizana pakati pa m'lifupi mwake kumatha kumangidwa pamanja ndikuphatikizana, ndi m'lifupi mwake osachepera 10cm.Ngati gululi wayikidwa mu zigawo zoposa ziwiri, zolumikizira pakati pa zigawo ziyenera kugwedezeka.Pambuyo pa kuyika malo akuluakulu, flatness yonse iyenera kusinthidwa.Pambuyo pophimba dothi, musanagubuduze, gululi liyenera kugwedezeka kachiwiri pogwiritsa ntchito zida zamanja kapena zamakina, ndi mphamvu yofananira, kuti gululi likhale lopanikizika molunjika m'nthaka.

Kusankhidwa kwa filler:

Wodzaza adzasankhidwa malinga ndi zofunikira za mapangidwe.Zochita zatsimikizira kuti kupatula nthaka yowuma, dothi lachinyontho, zinyalala zapanyumba, dothi lachoko, ndi diatomite, zonsezi zitha kugwiritsidwa ntchito ngati zida zamsewu, koma nthaka yamiyala ndi mchenga zili ndi zida zokhazikika zamakina ndipo zimakhudzidwa pang'ono ndi kuchuluka kwa madzi. zofunikira, choncho ziyenera kusankhidwa mwapadera.Kukula kwa tinthu ting'onoting'ono kodzaza sikuyenera kukhala kopitilira 15cm, ndipo chidwi chidzaperekedwa pakuwongolera kuyika kwa zodzaza kuti zitsimikizire kulemera kwake.

Kufalitsa ndi kuphatikizika kwa zinthu zodzaza:

Gululi litayikidwa ndikuyikidwa, liyenera kudzazidwa ndi kutsekedwa panthawi yake.Nthawi yowonekera sayenera kupitirira maola 48.Njira yoyendetsera njira yoyikira ndi kubwezeretsanso ikhoza kutengedwa.Pangani zodzaza misewu kumapeto onse a gombe, konzani gululi, kenako pita chapakati.

Njira yogudubuza imayambira mbali zonse ziwiri mpaka pakati.Pakugubuduza, chodzigudubuza sichidzalumikizana mwachindunji ndi zinthu zolimbikitsira, ndipo magalimoto nthawi zambiri samaloledwa kuyendetsa pamatupi olimbikitsira osasunthika kuti apewe kusuntha kwa zinthu zolimbikitsira.Kutalika kwa tsinde ndi 20-30 cm.Kuthirira kuyenera kukwaniritsa zofunikira za kapangidwe kake, komwenso ndi chinsinsi cha kupambana kwa uinjiniya wanthaka.

Njira zoletsa madzi ndi ngalande:

Mu kulimbitsa nthaka zomangamanga, m'pofunika kuchita ntchito yabwino ngalande mankhwala mkati ndi kunja kwa khoma;Chitani ntchito yabwino yoteteza mapazi ndi kupewa kukokoloka;Zosefera ndi ngalande ziyenera kuperekedwa m'nthaka, ndipo geotextile idzaperekedwa ngati kuli kofunikira.
