Mukuita engineering kuvaka maitiro, takapfupikisa maitiro ekuvaka egeogrids:
1. Nzvimbo yekuvaka ye geogrid: Inodiwa kuti ibatanidzwe uye ienzaniswe, muchimiro chakachinjika, uye kubvisa zvinhu zvakapinza uye zvakabuda.
2. Kuiswa kwegeogrid: Panzvimbo yakati sandara uye yakamanikana, iyo huru yekusimbisa kutungamira (longitudinal) yeiyo yakaiswa geogrid inofanira kunge iri perpendicular kune eembankment axis direction, uye yekuisa kunofanirwa kuve yakati sandarara, isina makwinya, uye inofanirwa kudzvanywa zvakanyanya senge. zvinogoneka.Yakagadziriswa nekuisa nekutsikirira pasi nedombo, iyo huru yekusimbisa kutungamira kwegridi yakagadzika ndiyo inonyanya kureba isina majoini, uye kubatana pakati pehupamhi hunogona kusungwa nemaoko uye kupindirana, nehupamhi hunopindirana kwete pasi pe10cm.Kana iyo grid yakaiswa mune anopfuura maviri akaturikidzana, majoini pakati pematanho anofanira kudzika.Mushure menzvimbo yakakura yekuisa yakaonda, flatness yayo inofanira kugadziriswa seyese.Mushure mekuvhara ivhu revhu uye risati rakunguruka, girasi rinofanira kusimbiswa zvakare ne manpower kana michina, neine simba rakafanana, kuitira kuti girasi iri mumamiriro ezvinhu akatwasuka muvhu.
3. Kusarudzwa kwekuzadza mushure mekupinda mu geogrid: Iyo yekuzadza ichasarudzwa maererano nezvinodiwa zvekugadzira.Kudzidzira kwakaratidza kuti zvese kunze kweivhu rakaomeswa nechando, ivhu remachakwi, marara emumba, ivhu rechoko, uye diatomite zvinogona kushandiswa sekuzadza.Nekudaro, ivhu remavhu nejecha rine yakagadzikana ma mechanical properties uye inobatwa zvishoma nemvura, saka dzinofanira kusarudzwa.Iyo particle size ye filler haifanire kunge yakakura kupfuura 15cm, uye kutarisisa kuchabhadharwa kudzora magiredhi eiyo filler kuti ive nechokwadi chekugadzirisa huremu.
4. Paving uye compaction ye key fillers mushure mekupedzwa kwe geogrid: Kana geogrid yaiswa uye yaiswa, inofanira kuzadzwa nekuvharwa nenguva.Nguva yekuratidzwa haifanirwe kudarika maawa makumi mana nemasere.Neimwe nzira, nzira yekuyerera yekudzosera kumashure paunenge uchiisa inogona kugamuchirwa.Pave filler kumativi ese maviri kutanga, gadzirisa grid, uye wozoenda mberi wakananga pakati.The rolling sequence kubva kumativi maviri kusvika pakati.Munguva yekukunguruka, roller haipokane nekubata zvakanangana neiyo yekusimbisa zvinhu, uye mota kazhinji hadzitenderwe kutyaira pane isina kusungirirwa mitumbi yekusimbisa kudzivirira kubviswa kwezvinhu zvekusimbisa.Iyo layer compaction degree ndeye 20-30cm.Kubatana kunofanirwa kusangana nezvinodiwa zvekugadzira, iyo zvakare ndiyo kiyi yekubudirira kweinjiniya yevhu yakasimbiswa.
5. Matanho ekupedzisira ekurapa kwekudzivirira kwemvura uye kudonha: Muinjiniya yevhu yakasimbiswa, zvakakosha kuita basa rakanaka rekuchenesa mukati nekunze kwemadziro;Chengetedza tsoka dzako uye kudzivirira kukukurwa.Sefa nematanho emvura achapihwa muhuremu hwevhu, uye kana zvichidikanwa, geotextile uye pombi dzinotenderedza (kana mapofu) achapihwa.Drainage ichaitwa nenzira yekudonhedza, pasina kuvharira, zvikasadaro njodzi dzakavanzika dzinogona kubuda.
