1. Chekutanga, nyatsoisa mutsara wemateru emugwagwa. Kuti uve nechokwadi chehupamhi hwemugwagwa, rutivi rumwe norumwe rwakawedzerwa ne 0.5m. Mushure mekuenzanisa ivhu rakaomeswa, shandisa 25T vibrating roller kune static press kaviri. Wobva washandisa 50T vibration kudzvinyirirwa kanokwana kana, uye nemaoko kuyera nzvimbo dzisina kuenzana.
2. Pave 0.3m gobvu yepakati, yakaoma, uye jecha, uye nemaoko pamwero nemichina. Static pressure kaviri ne25T vibrating roller.
3. Isa geogrid. Pakuisa geogrids, nzvimbo yepasi inofanira kunge yakati sandara, yakaoma, uye kazhinji yakati sandarara. Taramisa, usapindirane, usapeta, kumonyoroka, uye kupindirana nema geogrids ari padyo ne0.2m. Izvo zvikamu zvinopindirana zvema geogrids zvinofanirwa kubatanidzwa ne8 # waya dzesimbi yega yega mita 1 pamwe negwara rakachinjika remugwagwa, uye kuiswa pane akaiswa geogrids. Gadzirisa pasi neU-nails yega yega 1.5-2m.
4. Mushure mekunge chikamu chekutanga che geogrid chaiswa, chikamu chechipiri che 0.2m gobvu yepakati, yakaoma, uye jecha rinozadzwa. Nzira yacho ndeyekutakura jecha kunzvimbo yekuvaka uye kuidzikisa kune rimwe divi remugwagwa, uye kushandisa bulldozer kusundira mberi. Chekutanga, zadza 0.1m mukati mehupamhi hwemamita maviri pamativi ese emugwagwa, wopeta iyo yekutanga layer ye geogrid kumusoro woizadza ne 0.1m yepakati, yakakora, uye jecha. Rambidza kuzadza nekusundidzira kubva kumativi ese kusvika pakati, uye rambidza michina yakasiyana kupfuura nekushanda pane geogrid isina kuzadza, yakakora, uye jecha. Izvi zvinogona kuve nechokwadi chekuti geogrid yakati sandara, kwete kutumbuka, kana kuunyana, uye kumirira chikamu chechipiri chepakati, chakakora, uye jecha kuti chienzaniswe. Horizontal kuyerwa kunofanirwa kuitwa kudzivirira kusaenzana kwekuzadza ukobvu. Mushure mekuenzanisa pasina chero kukanganisa, 25T vibrating roller inofanirwa kushandiswa kune static pressure kaviri.
5. Nzira yekuvaka yechikamu chechipiri che geogrid yakafanana neyekutanga. Pakupedzisira, zadza 0.3m yepakati, yakakasharara, uye jecha nenzira yekuzadza yakafanana neyekutanga. Mushure memapasi maviri ekumanikidzwa kwakasimba ne 25T roller, kusimbiswa kwebhesi remugwagwa kunopedzwa.
6. Mushure mechikamu chechitatu chepakati, chakakora, uye jecha rabatanidzwa, ma geogrid maviri anoiswa kureba achitevedza mutsara kumativi ose emutsetse, achipindirana ne 0.16m, uye akabatanidzwa achishandisa nzira imwechete asati atanga basa rekuvaka ivhu. Isa ma geogrids ekudzivirira materu. Mitsetse yekumucheto yakaiswa inofanirwa kuyerwa pane yega yega. Rutivi rumwe norumwe runofanira kuona kuti geogrid yakavigwa mukati me 0.10m yemateru mushure mekugadzirisa materu.
7. Paunenge uchizadza zvidimbu zviviri zvevhu nehupamhi hwe 0.8m, jira re geogrid rinoda kuiswa kumativi ose emateru panguva imwe chete. Zvadaro, zvichingodaro, kusvikira yaiswa pasi pevhu pamusoro pemugwagwa wepfudzi.
8. Mushure mokunge mugwagwa wakazara, mutsetse unofanirwa kugadziriswa panguva yakakodzera. Uye kupa kudzivirirwa kwakaoma kwemarara patsoka yemateru. Pamusoro pekuwedzera kune rumwe rutivi ne0.3m, kugadzirisa kwe1.5% kwakachengeterwawo chikamu ichi chemugwagwa.
