Kukhazikitsa kwa HDPE geomembrane

Chithandizo cha maziko a malo

1. Musanayike geomembrane ya HDPE, malo oyikapo adzawunikiridwa mokwanira pamodzi ndi madipatimenti oyenera.Choyikapo chizikhala cholimba komanso chophwanyika.Sipadzakhala mizu yamtengo, zinyalala, miyala, tinthu tating'ono ta konkriti, mitu yolimbikitsira, tchipisi tagalasi ndi zinyalala zina zomwe zingawononge geomembrane mkati mwa kuya kwa 25 mm.Gwiritsani ntchito makina opangira magudumu kuti muphatikizepo kuchotsa zizindikiro za galimoto, mapazi ndi madontho apansi.Kuphatikiza apo, zotupa zapansi zokulirapo kuposa 12mm ziyeneranso kudulidwa kapena kuphatikizika.
2. Pamene HDPE geomembrane yaikidwa pa backfill, compactness wa backfill si kuchepera 95%.
3.Maziko a malowa azikhala opanda madzi otayira, zinyalala, dziwe, zotsalira za organic ndi zinthu zovulaza zomwe zingayambitse kuipitsa chilengedwe.Ngodya ya m'munsi ikhale yosalala.Nthawi zambiri, arc radius yake siyenera kuchepera 500 mm.

Zofunikira zaukadaulo pakukhazikitsa kwa HDPE geomembrane.

1. Kuyala ndi kuwotcherera kwa HDPE geomembrane kuyenera kuchitika nyengo yomwe kutentha kuli pamwamba pa 5 ℃ ndipo mphamvu ya mphepo imakhala pansi pa Sitandade 4 popanda mvula kapena matalala.
2. Ntchito yomanga ya HDPE geomembrane idzachitika motere: kuyika kwa geomembrane → zolumikizira zowotcherera → kuwotcherera → kuyang'ana pamalopo → kukonza → kuyang'ananso → kubwezeretsanso.
3. M'lifupi mwake molumikizana mafupa pakati pa nembanemba sikuyenera kuchepera 80mm.Nthawi zambiri, njira yolumikizirana idzakhala yofanana ndi mzere wotsetsereka, ndiye kuti, idzakonzedwa motsatira njira yotsetsereka.
4. Pakuyika kwa HDPE geomembrane, makwinya ochita kupanga apewedwe momwe angathere.Mukayala HDPE geomembrane, kufalikira kwapang'onopang'ono komwe kumachitika chifukwa cha kusintha kwa kutentha kumasungidwa molingana ndi kusintha kwa kutentha komweko komanso zofunikira za HDPE geomembrane.Kuonjezera apo, kuchuluka kwa geomembrane kudzasungidwa molingana ndi malo a malo ndi kuyika kwa geomembrane kuti zigwirizane ndi kukhazikitsidwa kosagwirizana kwa maziko.
5. Pambuyo pa kuikidwa kwa geomembrane ya HDPE, kuyenda pa membrane pamwamba ndi zida zogwirira ntchito ziyenera kuchepetsedwa.Zinthu zomwe zingayambitse kuwonongeka kwa HDPE geomembrane sizidzayikidwa pa geomembrane kapena kunyamulidwa pa geomembrane kuti zisawonongeke mwangozi nembanemba ya HDPE.
6. Onse ogwira ntchito pa malo opangira mafilimu a HDPE sayenera kusuta, kuvala nsapato zokhala ndi misomali kapena nsapato zolimba zolimba kuti ayende pamwamba pa filimuyo, kapena kuchita chilichonse chomwe chingawononge filimuyo.
7. Pambuyo pa kuikidwa kwa geomembrane ya HDPE ndipo chitetezo chisanaphimbidwe, thumba la mchenga la 20-40Kg lidzayikidwa pakona ya nembanemba 2-5m iliyonse kuti geomembrane isawombedwe ndi mphepo.
8. HDPE geomembrane idzakhala yachilengedwe komanso pafupi ndi gawo lothandizira, ndipo silidzapindidwa kapena kuyimitsidwa mlengalenga.
9. Pamene geomembrane imapangidwa m'zigawo, gawo lapamwamba lidzaphimbidwa ndi nthawi pambuyo pa kuyika, ndipo nthawi yowonekera mumlengalenga sayenera kupitirira masiku 30.
Kuyika kwa HDPE geomembrane kudzachitika molingana ndi kapangidwe kake.M'malo omwe ali ndi malo ovuta mu polojekitiyi, gawo lomangamanga lidzafotokozera njira zina zoyikira, zomwe zidzachitike pambuyo polandira chilolezo cha gulu lokonzekera ndi gulu loyang'anira.

HDPE geomembrane kuwotcherera zofunika:

1. Kuphatikizika kwa HDPE geomembrane weld kudzakhala kopanda dothi, mchenga, madzi (kuphatikiza mame) ndi zonyansa zina zomwe zimakhudza mtundu wa kuwotcherera, ndipo ziyenera kutsukidwa pakuwotcherera.
2. Kumayambiriro kwa kuwotcherera tsiku lililonse (m'mawa ndi pambuyo popuma nkhomaliro), kuyesa kuwotcherera kuyenera kuchitidwa pamalowo poyamba, ndipo kuwotcherera kovomerezeka kungatheke pokhapokha atayenerera.
3. Geomembrane ya HDPE iyenera kutenthedwa ndi makina awiri otsekemera otentha-otentha, ndipo kuwotcherera kwa extrusion kapena kuwotcherera kwamfuti yotentha kumayenera kugwiritsidwa ntchito m'malo omwe makina okonzera, ophimba kapena otentha otentha sangathe kufika.
4. Panthawi yomanga, kutentha kwa ntchito ndi liwiro la makina otsekemera zidzasinthidwa ndikuyendetsedwa nthawi iliyonse malinga ndi kutentha ndi zinthu zakuthupi.
Kanema wa 5.HDPE pa weld adzawotcherera kwathunthu, ndipo sipadzakhala kuwotcherera kwabodza, kuwotcherera kosowa kapena kuwotcherera kwambiri.Magawo awiri olumikizidwa a HDPE geomembrane ayenera kukhala osalala komanso odekha.

Weld khalidwe kulamulira

Ndi kupita patsogolo kwa zomangamanga, ndikofunikira kuyang'ana momwe kuwotcherera kwa filimu ya HDPE munthawi yake, ndikukonza zowotcherera ndi mfuti yamoto yotentha kapena mfuti yowotcherera ya pulasitiki nthawi iliyonse chifukwa chosowa kuwotcherera ndi zolakwika zowotcherera.Njira zenizeni ndi izi:
1.Kuyendera kukuchitika m'magawo atatu, omwe ndi kuyang'anitsitsa, kuyang'ana kwa inflation ndi kuyesa kuwonongeka.
2. Kuyang'ana kowoneka: fufuzani ngati ma welds awiriwo ndi athyathyathya, owoneka bwino, opanda makwinya, owoneka bwino, opanda slag, kuwira, kutayikira, malo osungunuka kapena weld bead.
Kuyang'anira zowoneka makamaka kuyang'ana mosamala maonekedwe a anaika geomembrane, weld khalidwe, T-zoboola pakati kuwotcherera, gawo lapansi zinyalala, etc. Onse ogwira ntchito yomanga adzagwira ntchito imeneyi mu njira zonse yomanga.
3. Kuphatikiza pa kuyang'ana kowonekera, kuyang'ana kwa vacuum kudzatengedwa kuti kukhale kolimba kwa ma welds onse, ndipo kudziyang'anira nokha kudzalimbikitsidwa kwa magawo omwe sangathe kuyesedwa ndi vacuum.
4. Mphamvu ya inflation yomwe imadziwika ndi kuthamanga kwa inflation ndi 0.25Mpa, ndipo palibe mpweya wotuluka kwa mphindi ziwiri.Poganizira kuti zinthu zophimbidwa ndi zofewa komanso zosavuta kupunduka, kutsika kovomerezeka ndi 20%
5. Poyesa kuyesa kwachitsulo pa chitsanzo chotengedwa kuchokera ku double rail weld, muyezo ndi wakuti weld sanang'ambika koma amayi amang'ambika ndi kuwonongeka panthawi yoyesa peel ndi kumeta ubweya.Panthawi imeneyi, kuwotcherera ndikoyenera.Ngati chitsanzocho sichiyenera, chidutswa chachiwiri chidzatengedwa kuchokera ku weld yapachiyambi.Ngati zidutswa zitatu zili zosayenera, weld yonse idzakonzedwanso.
6. Zitsanzo zopambana mayeso zidzaperekedwa kwa Mwini, General Contractor ndi mayunitsi oyenerera kuti asungidwe.
7. Zowonongeka zomwe zimapezeka poyang'ana zowona, kufufuza kwa inflation ndi kuyesa zowonongeka zidzakonzedwa panthawi yake.Zomwe sizingakonzedwe nthawi yomweyo ziyenera kulembedwa kuti zisawonongeke panthawi yokonza.
8. Poyang'anitsitsa maonekedwe, ngati pali zolakwika monga mabowo pa nembanemba pamwamba ndi kusowa kuwotcherera, kuwotcherera kolakwika ndi kuwonongeka panthawi yowotcherera, zitsulo zatsopano zidzagwiritsidwa ntchito kukonzanso nthawi, ndipo mbali iliyonse ya chilonda chokonzedwa chidzapitirira gawo lowonongeka ndi 10-20cm.Lembani zolemba.
9. Kwa wowotcherera wokonzedwa, kuyang'anitsitsa kwatsatanetsatane kudzachitidwa kawirikawiri, ndipo kumasulidwa kudzachitidwa pambuyo poti kukonzanso kutsimikiziridwa kukhala kodalirika.
