Igipimo cyo gushyira hamwe geomembrane

Imikorere yubuzima bwa geomembrane ikora igenwa ahanini nimba firime ya plastike ikorerwa imiti yica amazi. Ukurikije amahame y’igihugu cy’Abasoviyeti, firime ya polyethylene ifite umubyimba wa 0.2m hamwe na stabilisateur y’ubuhanga bw’amazi irashobora gukora imyaka 40 kugeza kuri 50 mu gihe cy’amazi meza n’imyaka 30 kugeza kuri 40 mu gihe cy’imyanda. Urugomero rwa Zhoutou mu ntangiriro rwahoze ari urugomero runini, ariko kubera urugomero rwasenyutse, igice cyo hejuru cyurukuta rwibanze cyavanyweho. Kugirango ukemure imikorere ya anti-seepage yo hejuru, urukuta rurwanya anti-seepage rwongewe kuri base. Dukurikije imyigaragambyo y’umutekano no kubora ku rugomero rw’ikigega cya Zhoutou, mu rwego rwo guhangana n’ubutaka bwangiritse ndetse n’urugomero rw’urugomero rwatewe n’isenyuka ryinshi ry’urugomero, imiterere y’imibiri idahwitse nko gutwikira umwenda wo kuryama, kurwanira hejuru y’intambara, gutemba no gufata neza umwenda usubira inyuma, hamwe nindege yumuvuduko ukabije wogukuta urukuta rwa plaque rwakoreshejwe muburyo bwo gukumira imyanda ihagaze.
Ibiranga geomembrane ikomatanya: Geomembrane igizwe nibintu bya geomembrane bigizwe na firime ya plastike nka substrate anti-seepage hamwe nigitambara kidoda. Imikorere yayo yo kurwanya seepage iterwa nibikorwa byo kurwanya seepage ya firime ya plastike. Uburyo bwayo bwo guhagarika umutima ni uko ubudahangarwa bwa firime ya pulasitike butuma inzira y’urugomero rw’amazi ava mu mazi, ikihanganira umuvuduko w’amazi kandi igahuza n’imihindagurikire y’urugomero bitewe n’ingufu nini nini kandi itinda; Imyenda idoda kandi ni ibikoresho bya chimique ya fibre ngufi ya polymer, ikorwa binyuze mu gukubita inshinge cyangwa guhuza ubushyuhe, kandi ifite imbaraga zingana no gutinda. Nyuma yo guhura na firime ya pulasitike, ntabwo yongerera imbaraga gusa imbaraga zo guhangana na firime ya plastike, ahubwo inongera coeffisiyoneri yo guterana hejuru yintambara kubera ibisobanuro bitomoye byimyenda idoda, ifitiye akamaro ituze rya geomembranes. no guhisha ibice.
Kubwibyo, ubuzima bwimikorere ya geomembrane irahagije kugirango uhaze ubuzima bwibikorwa byasabwe kugirango hirindwe ingomero.
Urukuta rwo hejuru ruhengamye rutwikiriwe na geomembrane igizwe no gukumira amazi y’amazi, igice cyo hepfo gikurikira urukuta rwo gukumira inkuta zihagaritse kandi igice cyo hejuru kigera ku butumburuke bwa 358.0m (0,97m hejuru y’urwego rw’imyuzure).
Kurwanya ubushyuhe bwinshi, imikorere myiza ya antifreeze.
Kugeza ubu, firime ya pulasitike ikoreshwa mu kugenzura imiyoboro y’imbere mu gihugu ndetse no hanze yarwo harimo polyvinyl chloride (PVC) na polyethylene (PE), ibyo bikaba ibikoresho bya polymer bihindura ibikoresho bifite uburemere buke, gutinda cyane, no guhuza cyane na deformasiyo.
Muri icyo gihe, bafite imbaraga zo kurwanya bagiteri no gukangurira imiti, kandi ntibatinya aside, alkali, n'umunyu.
