Kunyangwe ma geogrids aine hunhu hwakanaka hwekuita uye achishandiswa zvakanyanya mukuvaka migwagwa mikuru, munyori anoona kuti chete nekuziva nzira dzekuvaka dzakaringana vanogona kutamba basa ravo rakakodzera.Semuenzaniso, vamwe vashandi vekuvaka vane nzwisiso isiriyo yekushanda kwekuisa geogrids uye havazive maitiro ekuvaka.Pachine zvimwe zvikanganiso mugadziriro yekuvaka panguva yekuvaka chaiko, uye kuita chaiko kunogona kukamurwa kuita zvinotevera zvinhu.:
(1) Nzira yekuisa isiriyo
Nzira dzekuisa zvisiri izvo zvakare kukanganisa mukuvaka kwegeogrids.Semuenzaniso, kune yekuisa kutungamira kwe geogrids, sezvo kushushikana kwekutungamira kwezvinhu zvegeogrid kuri kunyanya unidirectional, zvinofanirwa kuve nechokwadi kuti kutungamira kwembabvu dzegeogrid kunoenderana nekunetsekana kwekutungamira kwelongitudinal majoini enzira panguva yekuisa, kuitira kuti tamba zvizere basa re geogrids.Zvisinei, vamwe vashandi vekuvaka havateereri nzira yekuisa.Panguva yekuvaka, vanowanzoisa geogrid kune imwe nzira yakatarisana neiyo longitudinal joint stress, kana geogrid centre inotsauka kubva pakati peiyo subgrade longitudinal joint, zvichikonzera kusagadzikana kusina kuenzana kumativi ose e geogrid.Nekuda kweizvozvo, kwete chete iyo geogrid haiite basa rayo rakakodzera, asi zvakare inokonzeresa kutambisa kwevashandi, zvinhu, uye mari yemuchina.
(2）Kushaikwa kwemichina yekuvaka
Nekuda kwekuti vazhinji vevashandi vekuvaka migwagwa mikuru havana kuwana dzidzo yehunyanzvi yekuvaka migwagwa, havanawo ruzivo rwakanaka rwehunyanzvi hwekuvaka hwezvinhu zvitsva, senge kupindirana kwekuvaka kwegeogrids, iyo isiripo.Izvi zvinodaro nekuti iyo geogrid inogadzirwa nemugadziri inoganhurwa nehukuru hwayo, uye hupamhi hwayo hunowanzo siyana kubva pamita imwe kusvika pamamita maviri, izvo zvinoda kuti ive nehumwe hupamhi hwepamusoro kana ichiisa chikamu chakakura.Nekudaro, nekuda kwekusakwana tekinoroji yekuvaka inogoneswa nevashandi vekuvaka, iyi poindi inowanzo furatirwa mukushanda.Kuwedzeredza kupindirana kunogona kukanganisa, uye kusakwana kana kusapindirana kunogona kutungamira kune isina kusimba mapoinzi anoparadzanisa maviri, kuderedza kushanda uye kushanda kwegeogrids.Mumwe muenzaniso ndewekuti pakuzadza uye kuenzanisa, iyo geogrid inoregeredza kushandiswa kwesainzi maitiro ekuvaka, zvichikonzera kukanganisa kune geogrid, kana kusakwana kurapwa panguva yekuzadza giredhi, kana kunyange kukuvadza kune geogrid panguva yekushandazve.Kunyangwe izvo zvinodikanwa zvekuvaka tekinoroji yegeogrids zvisina kukwirira, izvi zviperevedzo muhunyanzvi zvakakanganisa hunhu hweinjiniya hwemugwagwa wese.
(3）Kusanzwisisa kwakakwana kwevashandi vekuvaka
Zvinodiwa zvekugadzira zvekuisa zvinhu zvegeogrid pa Expressways zvine kuomarara, asi vamwe vashandi vekuvaka havana ruzivo rwakakwana rwekuita nekuvaka kwegeogrids.Kuti uchengetedze nguva, basa, uye zvinhu, kazhinji havateveri dhizaini yekutanga yekuvaka, uye nekugadzirisa kana kudzima kushandiswa kwema geogrids, nekudaro vachidzikisa kunaka kwekuvaka kweXX Expressway, iyo isingagone kuvimbiswa zvinobudirira.Semuenzaniso, kuitira kuti ubate nguva yekuvaka, geogrid haina kuiswa zvakasimba, kana nguva yekuisa zvinhu zvisati zvazara kwenguva refu, uye pane zvakawanda zvekunze zvinogona kukanganisa kushanda uye kushanda kwegeogrid, zvakadai semhepo. , vanofamba netsoka, uye motokari.Haisi chete iyo mhando yekuvaka inogona kuvimbiswa, asi kana iyo geogrid ikaiswazve, ichaparadzawo nguva uye kukanganisa kufambira mberi kwenguva yekuvaka.
