Njira zopangira geomembrane

Gawo logona liyenera kusanjidwa ndikusintha wosanjikiza wokhala ndi makulidwe pafupifupi 30 cm ndi tinthu tating'ono ting'onoting'ono 20 mm cha gulu la geomembrane.Momwemonso, gawo la fyuluta liyenera kuikidwa pa nembanemba, ndikutsatiridwa ndi chitetezo.Mphepete mwa nembanembayo iyenera kuphatikizidwa mwamphamvu ndi wosanjikiza wosanjikiza wa mapiri a banki pamabanki onsewo.Kulumikizana pakati pa nembanemba yosasunthika ndi poyambira nangula kumatsimikiziridwa kutengera kulumikizidwa kovomerezeka pakati pa nembanemba ndi konkriti.Mafilimu a polyvinyl chloride ndi mphira wa butyl amatha kutsatiridwa bwino pamwamba pa konkriti pogwiritsa ntchito zomatira kapena zosungunulira, motero kutalika kwake kumatha kukhala kofupikitsa moyenera.Chifukwa cha kulephera kwa filimu ya polyethylene kumamatira pamwamba pa konkire, kutalika kwa konkire ophatikizidwa kudzakhala osachepera 0,8m.

Geomembrane ndi chinthu cha geosynthetic chokhala ndi madzi otsika kwambiri.Kuti nembanembayo igwire ntchito yake yopewera kuseweredwa, kuwonjezera pakufuna kuti nembanembayo ikhale yosasunthika, chidwi chiyeneranso kuperekedwa ku khalidwe la zomangamanga la kuyala kansalu kosasunthika.

1. Kulumikizana pakati pa nembanemba yosasunthika ndi malire ozungulira.Nembanemba yosasunthika iyenera kulumikizidwa mwamphamvu ndi malire ozungulira.Panthawi yomanga, anchor groove akhoza kukumbidwa kuti agwirizane ndi maziko ndi malo otsetsereka a banki.

Ngati maziko ndi osaya mchenga permeable wosanjikiza, mchenga ayenera kukumba mpaka wolemera mu thanthwe, ndiyeno m'munsi konkire ayenera kuthiridwa kukonza geomembrane mu konkire.Ngati maziko ndi dongo wosanjikiza wosanjikiza, ngalande ya nangula yokhala ndi kuya kwa 2m ndi m'lifupi mwake pafupifupi 4m imatha kukumbidwa.Geomembrane imayikidwa mu ngalandeyo, ndiyeno dongo limadzaza kwambiri.Ngati mazikowo ndi mchenga wakuya ndi miyala, geomembrane ingagwiritsidwe ntchito kuphimba kuti isawonongeke, ndipo kutalika kwake kumatsimikiziridwa potengera kuwerengera.

Kulumikizana kwapakati pakati pa nembanemba yosasunthika ndi zinthu zothandizira ziyenera kukhala zosalala momwe zingathere kuti nembanemba isataye mphamvu yake yosasunthika poboola pamtunda.Kupanda kutero, gawo lotenthetsera bwino liyenera kuperekedwa kuti filimuyo isawonongeke.

3. Kulumikizana kwa nembanemba yosasunthika yokha.Njira zolumikizirana za filimu yonyowa yosasunthika zitha kufotokozedwa mwachidule m'mitundu itatu, yomwe ndi njira yolumikizirana, njira yowotcherera, ndi njira yavulcanization.Kusankhidwa kumadalira mitundu yosiyanasiyana ya filimu yosasunthika, ndipo kusasunthika kwa ziwalo zonse zogwirizanitsa ziyenera kufufuzidwa.Gulu la geomembrane liyenera kugwiritsidwa ntchito popewa kutayikira chifukwa cholumikizana molakwika.
