Igikorwa cyo gushyira Geomembrane, mugihe uhuye nibidukikije byumuyaga, none nigute ushobora kuryama mubidukikije kugirango umuyaga ugere kubisubizo byiza, nigute ushobora guhuha ibidukikije umuyaga? Hano hari inzira zimwe zo kubikora.
Kubika no gutunganya imirimo mbere yo gushyira geomembrane, umuzingo wa geomembrane ugomba kwirinda kandi ukagenzurwa ko wangiritse mbere yo kwishyiriraho, geomembrane igomba gushyirwa ahantu hahanamye kandi hatarimo amazi hamwe nuburebure bwikirundo butarengeje uburebure bwimizingo ine kandi ikimenyetso kiranga imizingo irashobora kuboneka; amabati yo hasi agomba gutwikirwa ibikoresho bidasobanutse kugirango wirinde gusaza UV.
Komeza ibirango hamwe namakuru neza mugihe cyo kubika; geomembranes igomba kurindwa ibyangiritse mugihe cyo gutwara kandi geomembran yangiritse kumubiri igomba gusanwa. Geotextile yakuweho cyane ntigomba gukoreshwa. Geomembrane iyo ari yo yose yahuye n’imiti isohoka ntabwo yemerewe gukoreshwa.
Uburyo bwo gushyira geomembrane mubidukikije byumuyaga bukoresha intoki anshun izunguruka; mugihe cyo kurambika, bigomba gukanda hamwe nubutaka burimo imifuka iboshye, hejuru yigitambara kiringaniye kandi amplitude ya deformasiyo irakwiriye; kwishyiriraho fibre ndende cyangwa ngufi ya geotextile mubisanzwe ikoresha uburyo bwinshi bwa lap, kudoda no gusudira. Ubugari bwo gusudira kubudodo buri hejuru ya 10 ~ 15cm, naho ubugari bwibibero bya lap biri hejuru ya 20cm. Geotextile ishobora kugaragara mugihe kirekire igomba gusudwa cyangwa kudoda.
Kudoda byose bigomba gukorwa ubudahwema mumuyaga mwinshi. Kudoda bigomba kuba bifite umutekano. Ubutaka bugomba guhuzagurika na 150mm mbere yo guhuzagurika. Intera yuburebure kuva kumpera yigitambara (impande zerekana ibintu) byibuze 25mm kandi amafaranga ya geomembrane agizwe numurongo hamwe numurongo wurunigi. Urudodo rukoreshwa mukudodo rugomba kuba ibikoresho bya resin hamwe nuburemere burenze 60N kandi bikagira imiti imwe cyangwa nini irwanya imishwarara ya UV kuruta geotextile. "Ubudodo bwabuze" muri geogrid idoda igomba gusubirwamo ahantu hafashwe.
