Geogrid kuisa maitiro:
Ongorora uye uchenese dhiri repasi → isa nemaoko geogrid → pindirana, sunga uye gadzirisa → gadzira ivhu rekumusoro → kukunguruka→ kuongorora.
Zvinhu zvekucherechedza kana uchiisa geogrid:
(1) Iyo geogrid inoradzikwa pane yakati sandara-yepasi-inotakura layer zvinoenderana nehupamhi hwakarongwa.Iyo yekumusoro yezasi layer yekuzadza haina marara anogona kukanganisa geogrid.Paunenge uchiisa geogrid, kutungamira kwesimba rakakwirira kunofanira kunge kune perpendicular kune axis ye embankment.layout.Iyo geogrid inoradzikwa yakatwasuka.Shinga uye tambanudza paunenge uchiisa kudzivirira makwinya, kukanganisa kana makomba.MaGeogrids akapatsanurwa kureba pachishandiswa nzira yekupiringishana, uye hupamhi hwepamusoro hausi pasi pe20cm.
(2) Mushure mekuisa geogrid, gadzira nemaoko chikamu chepamusoro chekuzadza uye kupedzisa kukunguruka nenguva kudzivirira kutarisana nezuva kwenguva refu.Zvadaro shandisa michina yekufambisa, kuenzana nekukunguruka.Mechanical paving uye rolling inoitwa kubva kumativi ese maviri kusvika pakati, uye kukunguruka kunoitwa kubva kumativi ese maviri kusvika pakati, uye iyo compaction degree inochengetwa kuti isangane nezvinodiwa zvakajairwa.
(3) Dzivirira mota dzese dzekuvaka nemichina yekuvaka kubva pakufamba kana kupaka pane yakarongwa geogrid.Tarisa kunaka kwegeogrid chero nguva panguva yekuvaka.Kana paine kukuvara kwakadai sekuputsika, kuboora, kana kubvaruka zvikawanikwa, gadzirisa zvinoenderana nekwakawanda.kana kutsiva.
Geogrid kuvaka nzira:
(1) Kutanga, nyatsoronga mutsara wemutsetse wemugwagwa.Kuti uve nechokwadi chehupamhi hwemugwagwa, rutivi rumwe norumwe rwakawedzerwa ne 0.5m.Mushure mekuenzanisa ivhu repasi rakavhurika, shandisa 25T vibratory roller kuitsikirira kaviri, wobva washandisa 50T vibratory roller kuitsikirira kana., kusaenzana kwenzvimbo yekudyidzana yekudyidzana kuenzana.
(2) Isa 0.3M gobvu yepakati (yakakomba) jecha, uye mushure mekuenzanisa nemichina yekushandira pamwe, shandisa 25T vibratory roller kuita static pressure kaviri.
(3) Isa geogrid.Paunenge uchiisa geogrids, pasi pepamusoro panofanira kuva sandara uye yakaoma.Kazhinji, dzinofanirwa kuiswa pasi, dzakatwasuka, uye kwete dzakaturikidzana.Havafaniri kumonyaniswa kana kumonyaniswa.Mageogridhi maviri akatarisana anoda kudhumhana ne 0.2m, uye ma geogrids anofanirwa kupetana akachinjika panzira.Zvikamu zvinosungirirwa zvakabatanidzwa neNo. 8 iron wire yega yega mita 1, uye grid yakagadzika inogadziriswa pasi neU-shaped misumari 1.5-2m imwe neimwe.
(4) Mushure mekunge chikamu chekutanga che geogrid chaiswa, tanga zadza chikamu chechipiri che 0.2m gobvu yepakati (yakakora) jecha.Nzira yacho ndeiyi: takura jecha kunzvimbo yekuvaka nemotokari uye uiburutse padivi pemugwagwa, uye woisundira mberi nebulldozer., tanga wazadza 0.1m mukati memamita maviri kumativi ose emugwagwa, peta chikamu chekutanga che geogrid, uye wozozadza ne 0.1m yejecha repakati (rakakomba).Zvinorambidzwa kuzadza nekusundidzira magumo maviri kusvika pakati, uye marudzi ese emuchina anorambidzwa.Paunenge uchishanda pane geogrid isina kuzadzwa nejecha repakati (rakakora), izvi zvinogonesa kuti geogrid yakati sandara, inoputika, uye isina kuunyana.Mushure mechikamu chechipiri chejecha repakati (rakaoma) rakati sandara, kuyerwa kwakatwasuka kunofanira kuitwa.Kudzivirira kusaenzana kwekuzadza ukobvu, shandisa 25T vibratory roller kuidzvanya kaviri mushure mekunge yaiswa.
(5) Nzira yekuvaka yechikamu chechipiri che geogrid yakafanana neyekutanga.Pakupedzisira, rizadze nejecha re 0.3M repakati (rakakomba).Iyo nzira yekuzadza yakafanana neyekutanga layer.Mushure mekudzvanya kaviri ne 25T roller, senge iyi Iyo bhedhi yenzira yekusimbisa inopedzwa.
(6) Mushure mechikamu chechitatu chejecha repakati (rakakora) rakungurutswa, isa ma geogrid maviri kumigumo yese yekuteremuka kureba pamutsara, achipindirana ne 0.16m, woabatanidza nenzira imwechete, uye wozotanga kuvaka kwevhu.Paunenge uchiisa geogrids yekudzivirira kwemateru, zvinodikanwa kuyera mitsetse yemupendero yega yega, uye kuve nechokwadi kuti geogrids inovigwa 0.10m mumatope mushure mekugadzirisa materu kune rumwe rutivi.
(7) Pazvikamu zviviri zvega zvevhu zvakazadzwa nemateru geogrid, ndiko kuti, kana ukobvu hwasvika 0.8m, geogrid inoda kuiswa kumigumo yese, zvichingodaro, kusvikira yaiswa pasi pevhu repamusoro. road shoulder.
(8) Mushure mekunge mugwagwa wazadzwa, mutsetse unofanirwa kugadziriswa nenguva, uye kuchengetedzwa kwemarara akaoma kunofanira kuitwa pasi pemateru.Pamusoro pekuwedzera mugwagwa ne0.3M padivi rega rega, 1.5% yekugadziriswa inofanira kuchengetwa.
