HDPE kwishyiriraho geomembrane

Kuvura urufatiro

1. Mbere yo gushyira geomembrane ya HDPE, ishingiro ryashyizweho rigomba kugenzurwa byimazeyo hamwe ninzego zibishinzwe.Urufatiro rwo gushiraho ruzaba rukomeye kandi ruringaniye.Ntihazabaho imizi yibiti, amatongo, amabuye, ibice bya beto, imitwe ishimangira, imitobe yikirahure nindi myanda ishobora kwangiza geomembrane muburebure bwa mm 25.Koresha uruziga rukora kugirango ukureho ibimenyetso byimodoka, ibirenge hamwe nubutaka.Byongeye kandi, ibibyimba byubutaka burenze 12mm nabyo bizacibwa cyangwa byegeranye.
2. Iyo HDPE geomembrane ishyizwe kumugongo winyuma, ubwuzuzanye bwinyuma ntibushobora kuba munsi ya 95%.
3.Urufatiro rwikibanza ntiruzaba rwuzuye amazi, isuka, ibyuzi, ibisigazwa kama nibintu byangiza bishobora kwangiza ibidukikije.Inguni y'ifatizo igomba kuba yoroshye.Mubisanzwe, radiyo ya arc ntishobora kuba munsi ya mm 500.

Ibisabwa bya tekinike yo kwishyiriraho HDPE geomembrane.

1. Gushyira no gusudira bya geomembrane ya HDPE bigomba gukorwa mugihe ikirere kiri hejuru ya 5 ℃ naho umuyaga ukaba uri munsi yicyiciro cya 4 nta mvura cyangwa shelegi.
2. Igikorwa cyo kubaka geomembrane ya HDPE kizakorwa muburyo bukurikira: gushira geomembrane → guhuza gusudira hamwe → gusudira → kugenzura aho hantu → gusana → kugenzura → gusubira inyuma.
3. Ubugari bwuzuye bwubugingo buri hagati ya membrane ntibushobora kuba munsi ya 80mm.Mubisanzwe, icyerekezo gihuriweho icyerekezo kizaba kingana numurongo ntarengwa, ni ukuvuga ko uzashyirwa kumurongo werekeza.
4. Mugihe cyo gushyira HDPE geomembrane, iminkanyari yubukorikori igomba kwirindwa bishoboka.Iyo ushyizeho geomembrane ya HDPE, ihinduka ryagutse ryatewe nihindagurika ryubushyuhe rigomba kubikwa ukurikije intera ihindagurika ryubushyuhe bwaho hamwe nibisabwa na HDPE geomembrane.Byongeye kandi, ubwiyongere bwa geomembrane bugomba kubikwa hakurikijwe ahantu hamwe no gushyira geomembrane kugirango ihuze n’imiturire idahwitse.
5. Nyuma ya HDPE geomembrane imaze gushyirwaho, kugendera hejuru ya membrane nibikoresho byo gukoresha bigomba kugabanuka.Ibintu bishobora kwangiza geomembrane ya HDPE ntibishobora gushyirwa kuri geomembrane cyangwa ngo bitwarwe kuri geomembrane kugirango birinde kwangirika kubwimpanuka ya HDPE.
6. Abakozi bose bari ahazubakwa firime ya HDPE ntibashobora kunywa itabi, kwambara inkweto zifite imisumari cyangwa inkweto ndende zikomeye kugirango bagende hejuru ya firime, cyangwa kwishora mubikorwa byose bishobora kwangiza firime itemewe.
7. Nyuma ya geomembrane ya HDPE imaze gushyirwaho kandi mbere yuko igipfundikizo gitwikirwa, umufuka wumucanga wa 20-40Kg uzashyirwa ku mfuruka ya membrane buri 2-5m kugirango wirinde geomembrane guhuhwa n umuyaga.
8. HDPE geomembrane igomba kuba karemano kandi yegereye urwego rushyigikiwe, kandi ntishobora kuzingirwa cyangwa guhagarikwa mukirere.
9. Iyo geomembrane yubatswe mubice, igice cyo hejuru kigomba gutwikirwa mugihe nyuma yo kuryama, kandi igihe cyagaragaye mukirere ntigishobora kurenza iminsi 30.
Inanga ya HDPE geomembrane igomba gukorwa hakurikijwe igishushanyo mbonera.Ahantu hamwe nubutaka bugoye mumushinga, ishami ryubwubatsi rigomba gutanga ubundi buryo bwo gufata ibyuma, bizakorwa nyuma yo kubyemererwa nishami rishinzwe igishushanyo n’ishami rishinzwe kugenzura.

HDPE geomembrane ibisabwa byo gusudira:

1. Ubuso bwuzuye bwa HDPE geomembrane weld igomba kuba idafite umwanda, umucanga, amazi (harimo ikime) nibindi byanduye bigira ingaruka kumiterere yo gusudira, kandi bizasukurwa mugihe cyo gusudira.
2. Mugutangira gusudira buri munsi (mugitondo na nyuma yikiruhuko cya sasita), gusudira ibizamini bigomba kubanza gukorerwa kurubuga, kandi gusudira kumugaragaro birashobora gukorwa nyuma yujuje ibyangombwa.
3. Geomembrane ya HDPE igomba gusudwa na mashini yo gusudira inshuro ebyiri zishyushye, kandi gusudira cyangwa gusohora imbunda zo mu kirere bigomba gukoreshwa gusa aho imashini yo gusana, gupfuka cyangwa gushyushya ubushyuhe idashobora kugera.
4. Mugihe cyubwubatsi, ubushyuhe bwakazi n'umuvuduko wimashini yo gusudira bigomba guhindurwa no kugenzurwa igihe icyo aricyo cyose ukurikije ubushyuhe nibintu.
5.HDPE ya firime kuri weld igomba gusudwa muri rusange, kandi ntihazabaho gusudira ibinyoma, kubura gusudira cyangwa gusudira cyane.Ihuza ibice bibiri bya HDPE geomembrane bigomba kuba bifunze neza kandi byoroheje.

Kugenzura ubuziranenge

Hamwe niterambere ryubwubatsi, birasabwa kugenzura ubuziranenge bwo gusudira bwa firime ya HDPE mugihe, no gusana gusudira ukoresheje imbunda ishyushye cyangwa imbunda yo gusudira ya plastike igihe icyo aricyo cyose kugirango habuze gusudira nibice byo gusudira nabi.Uburyo bwihariye nuburyo bukurikira:
1.Ubugenzuzi bukorwa mubyiciro bitatu, aribyo kugenzura amashusho, kugenzura ifaranga no gupima ibyangiritse.
2. Igenzura ryibonekeje: reba niba gusudira byombi biringaniye, bisobanutse, bitagira inkari, bisobanutse, slag yubusa, ibibyimba, ibimeneka, aho gushonga cyangwa isaro.
Igenzura rigaragara cyane cyane ni ukugenzura neza isura ya geomembrane yashyizweho, ubuziranenge bwo gusudira, gusudira T-gusudira, imyanda ya substrate, nibindi. Abakozi bose bubaka bazakora iki gikorwa mubikorwa byose byubwubatsi.
3. Usibye ubugenzuzi bugaragara, hagomba no kugenzurwa vacuum kugirango ubukana bwa weld zose, kandi igenzurwa ryonyine rizashimangirwa kubice bidashobora kugenzurwa na vacuum.
4. Imbaraga zifaranga zagaragajwe nigitutu cy’ifaranga ni 0.25Mpa, kandi nta mwuka uva mu minota 2.Urebye ko ibikoresho bifunitse byoroshye kandi byoroshye guhindura, kugabanuka k'umuvuduko ni 20%
5. Iyo ukora ikizamini cya tensile kuri sample yakuwe muri kaburimbo ya gari ya moshi ebyiri, igipimo ni uko gusudira bidatanyaguwe ariko umubyeyi arashwanyagurika kandi yangiritse mugihe cyo gupima ibishishwa.Muri iki gihe, gusudira birujuje ibisabwa.Niba icyitegererezo kitujuje ibyangombwa, igice cya kabiri kizakurwa muri weld yambere.Niba ibice bitatu bitujuje ibyangombwa, gusudira byose bizongera gukorwa.
6. Ingero zatsinze ikizamini zishyikirizwa nyirazo, rwiyemezamirimo rusange hamwe ninzego zibishinzwe kugirango batange.
7. Inenge ziboneka mu igenzura rigaragara, kumenya ifaranga no gupima ibyangiritse bigomba gusanwa mu gihe gikwiye.Ibidashobora gusanwa ako kanya bigomba gushyirwaho ikimenyetso kugirango birinde gusiba mugihe cyo gusana.
8. Mu igenzura ryigaragara, mugihe habaye inenge nkumwobo uri hejuru ya membrane no kubura gusudira, gusudira nabi no kwangirika mugihe cyo gusudira, ibyuma shingiro bizakoreshwa mugusana mugihe, kandi impande zose zinkovu zasanwe zirenze igice cyangiritse kuri 10-20cm.Kora inyandiko.
9. Kuri weld yasanwe, igenzura rirambuye rigomba gukorwa muri rusange, kandi kurekura bizakorwa nyuma yo gusanwa byemejwe ko byizewe.
