Urugomero rwamazi geomembrane
Ibisobanuro bigufi:
- Geomembranes ikoreshwa ku ngomero z’ibigega ikozwe mu bikoresho bya polymer, cyane cyane polyethylene (PE), chloride polyvinyl (PVC), nibindi. Ibyo bikoresho bifite amazi make cyane kandi birashobora kubuza amazi kwinjira. Kurugero, polyethylene geomembrane ikorwa hifashishijwe reaction ya polymerisation ya Ethylene, kandi imiterere ya molekile yayo iroroshye kuburyo molekile zamazi zidashobora kuyinyuramo.

1.Ibiranga imikorere
- Imikorere yo kurwanya seepage:
Nibikorwa byingenzi bya geomembrane mugukoresha ingomero zamazi. Geomembranes yo mu rwego rwo hejuru irashobora kugira coeffisente yinjira igera kuri 10⁻¹² - 10⁻¹³ cm / s, hafi yo guhagarika inzira y'amazi. Ugereranije n’ibumba gakondo rirwanya seepage, ingaruka zaryo zo kurwanya seepage ziragaragara cyane. Kurugero, munsi yumuvuduko umwe wumutwe wamazi, ubwinshi bwamazi yinjira muri geomembrane nigice gito cyayo binyuze mubumba anti-seepage. - Imikorere yo kurwanya puncture:
Mugihe cyo gukoresha geomembranes ku ngomero z’ibigega, zirashobora gutoborwa nibintu bikarishye nkamabuye n'amashami imbere yumubiri. Geomembran nziza ifite imbaraga nyinshi zo kurwanya puncture. Kurugero, ibice bimwe bya geomembran bifite ibice byimbere bya fibre byongera imbaraga bishobora kurwanya gucumita. Muri rusange, imbaraga zo kurwanya puncture za geomembran zujuje ibyangombwa zishobora kugera kuri 300 - 600N, zikareba ko zitazangirika byoroshye mubidukikije bigoye byumubiri wurugomero. - Kurwanya gusaza:
Kubera ko ingomero z’ibigega zifite igihe kirekire cyo gukora, geomembranes igomba kugira gusaza neza. Imiti igabanya ubukana yongewemo mugihe cyo kubyara geomembranes, ibafasha gukomeza gukora neza igihe kirekire bitewe n’ibidukikije nk’imirasire ya ultraviolet n’imihindagurikire y’ubushyuhe. Kurugero, geomembranes yatunganijwe hamwe nubuhanga bwihariye birashobora kugira ubuzima bwumurimo wimyaka 30 - 50 hanze. - Guhuza n'imihindagurikire y'ikirere:
Urugomero ruzagira impinduka zimwe nko gutura no kwimurwa mugihe cyo kubika amazi. Geomembranes irashobora guhuza nuburyo bugaragara butavunitse. Kurugero, zirashobora kurambura no kugunama kurwego runaka hamwe no gutura umurambo wurugomero. Imbaraga zabo zingana zirashobora kugera kuri 10 - 30MPa, zikabafasha guhangana nihungabana riterwa no guhindura umubiri wurugomero.
kness ukurikije ibikenewe byumushinga. Ubunini bwa geomembrane mubusanzwe ni 0.3mm kugeza kuri 2.0mm.
- Kudahinduka: Menya neza ko geomembrane ifite ubudahangarwa bwiza bwo kubuza amazi mu butaka kwinjira mu mushinga.
2.Ubwubatsi Ingingo z'ingenzi
- Umuti shingiro:
Mbere yo gushyira geomembranes, umusingi wurugomero ugomba kuba uringaniye kandi rukomeye. Ibintu bikarishye, ibyatsi bibi, ubutaka bworoshye nubutare hejuru yikibanza bigomba kuvaho. Kurugero, ikosa ryibanze ryibanze risabwa kugenzurwa muri ± 2cm. Ibi birashobora kubuza geomembrane gushushanya kandi ikemeza ko habaho imikoranire myiza hagati ya geomembrane na base kugirango imikorere yayo yo kurwanya seepage ikorwe. - Uburyo bwo Gushiraho:
Ubusanzwe Geomembranes iterwa no gusudira cyangwa guhuza. Iyo gusudira, birakenewe kwemeza ko ubushyuhe bwo gusudira, umuvuduko nigitutu bikwiye. Kurugero, kuri geomembranes yubushyuhe, ubushyuhe bwo gusudira muri rusange buri hagati ya 200 - 300 ° C, umuvuduko wo gusudira ni 0.2 - 0.5m / min, naho umuvuduko wo gusudira uri hagati ya 0.1 - 0.3MPa kugirango ubashe gusudira no gukumira ibibazo byo kumeneka biterwa no gusudira nabi. - Ihuza rya Periferiya:
Guhuza geomembrane nishingiro ryurugomero, imisozi kumpande zombi zurugomero, nibindi kuruhande rwurugomero ni ngombwa cyane. Mubisanzwe, imiyoboro ya ankoring, gufata beto, nibindi bizakirwa. Kurugero, umwobo wa ankoring ufite ubujyakuzimu bwa 30 - 50cm ushyirwa ku rugomero. Impera ya geomembrane ishyirwa mu mwobo wa ankeri hanyuma igashyirwaho ibikoresho byubutaka byegeranye cyangwa beto kugirango barebe ko geomembrane ifitanye isano rya bugufi n’inzego ziyikikije kandi ikarinda kumeneka.
3.Gufata neza no kugenzura
- Kubungabunga Gahunda:
Birakenewe kugenzura buri gihe niba hari ibyangiritse, amarira, gucumita, nibindi hejuru ya geomembrane. Kurugero, mugihe cyibikorwa byurugomero, abakozi bashinzwe kubungabunga barashobora gukora igenzura rimwe mukwezi, bakibanda kugenzura geomembrane mubice aho amazi y’amazi ahinduka kenshi hamwe n’ahantu hafite imiterere nini y’urugomero. - Uburyo bwo Kugenzura:
Tekinike yo kwangiza idasenya irashobora gukoreshwa, nkuburyo bwo gupima ikibatsi. Muri ubu buryo, voltage runaka ikoreshwa hejuru ya geomembrane. Iyo hari ibyangiritse kuri geomembrane, hazavamo ibishashi, kugirango ingingo zangiritse zishobora kuboneka vuba. Mubyongeyeho, hariho nuburyo bwo gupima vacuum. Umwanya ufunze ukorwa hagati ya geomembrane nigikoresho cyo kwipimisha, kandi kubaho kwa geomembrane kugenzurwa no kureba ihinduka ryurwego rwa vacuum.
Ibipimo byibicuruzwa
