Composite geomembrane inoshandiswa zvakanyanya mu canal seepage kudzivirira engineering.Mumakore achangopfuura, kushandiswa kwakawanda uye kubudirira kweiyo geotechnical decomposition data mu civil engineering, kunyanya mukudzora mafashama uye mapurojekiti ekununura ekukurumidzira, yakakwezva kutarisisa kwakanyanya kubva kune vane hunyanzvi engineering technician.Nezve nzira dzekushandisa dze geotechnical decomposition data, nyika yakaronga nzira dzakamisikidzwa dzekudzivirira kuyerera, kusefa, kudhiraivha, kusimbisa, nekudzivirira, ichimhanyisa zvakanyanya kusimudzira nekushandiswa kwedata idzva.Ruzivo urwu rwakashandiswa zvakanyanya mumapurojekiti ekudzivirira canal seepage munzvimbo dzekudiridza.Zvichienderana nedzidziso yekuvaka pamwe chete, bepa rino rinokurukura maitiro ekushandisa ecomposite geomembrane.
Composite geomembrane inoumbwa geomembrane inoumbwa nekudziya imwe kana mativi ese ari maviri e membrane muhovhoni yekure infrared, kudzvanya geotextile uye geomembrane pamwechete kuburikidza negidhi roller.Nekufambira mberi kwe tekinoroji yevashandi, kune imwe nzira yekukanda composite geomembrane.Mamiriro acho anosanganisira jira rimwe uye firimu rimwe, machira maviri uye firimu rimwe chete, uye maviri firimu nejira rimwe.
Sechidziviriro chegeomembrane, iyo geotextile inodzivirira iyo inodzivirira uye isingapindike layer kuti isakuvare.Kuti uderedze ultraviolet mwaranzi uye kuwedzera kushanda, zvinokurudzirwa kutora embedding nzira yekuisa.
Panguva yekuvaka, tanga shandisa jecha kana ivhu rine dhayamita diki yezvinhu kuti uenzanise hwaro hwepamusoro, wozoisa geomembrane.Iyo geomembrane haifanirwe kutambanudzwa zvakanyanya, iine migumo yese yakavigwa muvhu mune marara chimiro.Pakupedzisira, shandisa jecha rakanaka kana ivhu kuisa 10cm transition layer pageomembrane yakavezwa.Vaka 20-30cm matombo ebhuroko (kana precast kongiri zvibhuroko) sechidziviriro pakukukurwa.Panguva yekuvaka, kuedza kunofanirwa kuitwa kudzivirira matombo kubva kune zvisina kunanga kurova geomembrane, zviri nani kumisa kuvakwa kwenhoo layer uchiisa membrane.Kubatana pakati peiyo composite geomembrane uye zvimiro zvakatenderedza zvinofanirwa kusungirirwa ne shrinkage mabhaudhi uye simbi simbi mabhero, uye iyo yekubatanidza inofanirwa kuputirwa ne emulsified asphalt (2mm gobvu) yekubatanidza kudzivirira kubuda.
Chiitiko chekugadzira
(1) Mhando yakavigwa ichagamuchirwa kuti ishandiswe: ukobvu hwekuvhara hauzove pasi pe30cm.
(2) Iyo yakagadziridzwa anti-seepage system inofanirwa kuve necushion, anti-seepage layer, transition layer, uye nhovo layer.
(3) Ivhu rinofanira kunge rakapfava kudzivirira kusagadzikana uye kutsemuka, uye turf nemidzi yemiti mukati meiyo isingapindike inofanira kubviswa.Isa jecha kana ivhu nehukuru hudiki hudiki sechidziviriro chepamusoro pamusoro pe membrane.
(4) Pakuisa, geomembrane haifanirwe kudhonzwa zvakanyanya.Zviri nani kupinza migumo miviri muvhu mune corrugated chimiro.Uye zvakare, kana uchimisa nedata rakasimba, imwe huwandu hwekuwedzera uye kuderera kunofanirwa kuchengetwa.
(5) Panguva yekuvaka, zvakakosha kudzivirira matombo uye zvinhu zvinorema kubva pane zvisina kunanga kurova geomembrane, kuvaka paunenge uchiisa membrane, uye kuvhara iyo inodzivirira layer.
