HDPE geomembraneimadziwikanso kuti polyethylene yosasunthika kwambiri ya geomembrane.Ndi mtundu wa zinthu zopanda madzi, zopangira zake ndi ma polima apamwamba kwambiri.Zigawo zazikuluzikulu ndi 97.5% ya HDPE ndi 2.5% ya Carbon wakuda / anti-aging agent / anti-oxygen / UV absorbent / stabilizer ndi zina zowonjezera.
Amapangidwa pogwiritsa ntchito njira yolumikizira katatu pogwiritsa ntchito zida zapamwamba kwambiri zomwe zimatumizidwa kuchokera ku Italy.
Ma geomembranes a Yingfan onse amakwaniritsa kapena kupitilira miyezo ya US GRI ndi ASTM.Ntchito yake yayikulu ndi anti-seepage ndi kudzipatula., kotero kuyika kwaHDPE geomembrane linerndizofunikira kwambiri.
Kuyika kwa HDPE geomembrane kumagwira ntchito yofunika kwambiri pama projekiti osalowa madzi komanso odana ndi masamba.Ife, Shanghai Yingfan Engineering Material Co., LTD, tili ndi gulu lathu laukadaulo laukadaulo kuti tipereke ntchito zoika pamalopo, zokumana nazo zaka zoposa khumi.Chifukwa chake ndikukhulupirira kuti bukhuli lingakuthandizenidi.
Bukuli likuwonetsa njira yoyika HDPE geomembrane.Kudzera mu bukhuli, mudziwa momwe mungayikitsire HDPE geomembrane ndikukuthandizani kuti musunge nthawi ndi ntchito.
Nthawi zambiri, njira yoyika ya HDPE geomembrane motere:
1) Kukonzekera unsembe
2) Chithandizo chapamalo
3) Kukonzekera kuyala HDPE geomembrane
4) Kuyala HDPE geomembrane
5) Kuwotcherera HDPE geomembrane
6) Yang'anani Ubwino
7) Konzani HDPE geomembrane
8) HDPE Geomembrane nangula
9) Muyeso woteteza
Ndiroleni ndidziwitse za kukhazikitsa kwa geomembrane mwatsatanetsatane pansipa:
1. Kukonzekera unsembe
1.1 Konzani malo athyathyathya mozungulira malowo (kukula:kukulirapo kuposa 8m*10m) potsitsa ndi kudula.
1.2 Tulutsani geomembrane mosamala.Ikani bolodi lamatabwa pamphepete mwa galimoto ndikugudubuza geomembrane kuchokera pagalimoto kudzera pamanja kapena makina.
1.3 Phimbani nembanembayo ndi chivundikiro china chosalowa madzi, pansi pa pedi yopanda kanthu.
2. Chithandizo chapamalo
2.1 Maziko oyikapo ayenera kukhala olimba komanso osalala.Sipayenera kukhala mizu, zinyalala, miyala, tinthu tating'ono ta konkriti, zitsulo zazitsulo, magalasi a galasi, ndi zina zotero zomwe zingawononge HDPE geomembrane .
2.2 Ngakhale m'munsi ndi m'mbali otsetsereka kwa thanki, pondani pamwamba ndi makina chifukwa thanki idzayima mwamphamvu kwambiri pambuyo pa kutsekedwa kwa madzi. khoma deformation chifukwa cha kuthamanga kwa madzi.Pamwamba payenera kukhala tamped. Ngati kuloledwa, konkire kapangidwe ayenera kukhala bwino.(Monga pansipa chithunzi.)
2.3.Phimbani polowera (kukula kwa 40cm*40cm) mozungulira thanki yamadzi kuti mukonzere HDPE geomembrane.
3. Peparation kwa kuyala HDPEgeomembrane
3.1 Pamwamba payenera kufika pamapangidwe ndi zofunikira zamtundu.
3.2 Ubwino wa HDPE geomembrane ndi ndodo yowotcherera ziyenera kufika pamapangidwe ndi zofunikira.
3.3 Anthu osagwirizana saloledwa kupita kumalo oyikapo.
3.4 Onse oyika ayenera kuvala pass ndi nsapato zomwe popanda kuwonongeka kwa HDPE geomembrane.No kusuta pa malo oikamo.
3.5 Zida zonse ziyenera kugwiridwa mofatsa.Zida zotentha siziloledwa kukhudza HDPE geomembrane.
3.6 Tengani njira zodzitetezera kuti muyike HDPE geomembrane.
3.7 Sitingathe kugwiritsa ntchito zida zomwe zingayambitse kuwonongeka kwa makina panthawi yotumiza.Njira zowonjezera zosalamulirika siziloledwa ndikugwira ntchito mosamala.
4. Kuyala HDPE geomembrane
4.1 Tsegulani geomembrane ya HDPE pamalo athyathyathya ndikudula zinthuzo kuti zikhale zofunikira.
4.2 Kuwonongeka kopangidwa ndi anthu kuyenera kupewedwa panthawi yoyika.Geomembrane iyenera kuikidwa bwino ndi kuchepetsa kutsekemera.
4.3 Kusintha kwa HDPE geomembrane kuyenera kukhala 1% -4%.
4.4 Ma geomembrane onse ofufuzidwa a HDPE akuyenera kukanikizidwa kudzera m'matumba a mchenga kapena zinthu zina zolemetsa kuti apewe kuwomba mphepo kwa geomembrane.
4.5 Kumanga panja kwa HDPE geomembrane kuyenera kupitirira 5 °C, ndipo kulibe mvula kapena nyengo yopanda chipale chofewa pansi pa mphepo zinayi.Mukayika geomembrane, msoko wa weld uyenera kuchepetsedwa.Pansi pa malo owonetsetsa kuti zinthu zili bwino, zopangira ziyenera kupulumutsidwa momwe zingathere, ndipo khalidweli likhoza kutsimikiziridwa mosavuta.
4.6 Kuyeza: kuyeza kukula kwa kudula;
4.7 Kudula: Kudula molingana ndi zosowa zenizeni;m'lifupi mwake ndi 10-15 cm.
5. Kuwotcherera HDPE geomembrane
5.1 Nyengo:
(1) Kutentha:4-40℃
(2) Kuyanika, palibe mvula kapena madzi ena
(3) Kuthamanga kwa mphepo ≤4 kalasi / h
5.2 kuwotcherera otentha:
5.2.1 Ma geomembrane awiri a HDPE ayenera kupindika osachepera 15cm.
5.2.2 Malo owotcherera amayenera kutsukidwa ndikuonetsetsa kuti palibe madzi, fumbi kapena zina.
5.2.3 Kuwotcherera kwa mayesero: Kuwotcherera koyesa kuyenera kuchitidwa ntchito yowotcherera isanayambe.Kuwotcherera mayeso kudzachitika pazitsanzo za zinthu zopanda pake zomwe zaperekedwa.Kutalika kwa chitsanzo sikuyenera kukhala kosachepera 1 m ndipo m'lifupi sikuyenera kuchepera 0.2 m.Kuwotcherera mayeso kukamalizidwa, zidutswa zitatu zoyeserera za 2.5 cm mulifupi zidadulidwa kuyesa mphamvu yong'ambika ndi mphamvu yakumeta ubweya.
5.2.4 kuwotcherera: The geomembrane ndi welded ntchito kukwawa mtundu wapawiri njanji kuwotcherera makina.Chowotcherera chowotcherera chotenthetsera chotentha chidzagwiritsidwa ntchito pomwe makina owotcherera njanji apawiri sangathe kugwira ntchito.Zimagwirizanitsidwa ndi ndodo yowotcherera ya zinthu zomwezo ndi geomembrane.Njira yowotcherera ili motere: kusintha kupanikizika, kuyika kutentha, kuyika liwiro, kuyang'ana kwamagulu, kuyika kwa geomembrane mu makina, kuyambitsa injini.Sipadzakhala mafuta kapena mafuta. fumbi pa mfundo, ndipo sipadzakhala zinyalala, condensation, chinyezi ndi zinyalala zina mu chilolo olowa pamwamba pa geomembrane.Ayenera kutsukidwa pamaso kuwotcherera.
5.3 kuwotcherera Extrusion;
(1) Ma HDPE geomembrane awiri akuyenera kupitirana osachepera 7.5cm.Malo owotcherera amayenera kutsukidwa ndikuonetsetsa kuti palibe madzi, fumbi kapena zina.
(2) kuwotcherera otentha sikungawononge HDPE geomembrane.
(3) Ndodo yowotchera iyenera kukhala yoyera ndi youma.
Kuwotcherera kotentha
Extrusion kuwotcherera
Pa kuwotcherera, kuteteza HDPE geomembrane windblown, ife kuyala ndi kuwotcherera nthawi yomweyo.Pamaso kuwotcherera, kuyeretsa malo kuwotcherera.Gulo la kuwotcherera makina ayeneranso kutsukidwa.Sinthani chizindikiro pamaso kuwotcherera.Pitirizani kuwotcherera makina kuthamanga ndi yunifolomu liwiro.Chongani kuwotcherera msoko pambuyo Kwathunthu utakhazikika.
6. Kuyendera khalidwe
6.1 Dziyeseni nokha: Onani ndikulemba tsiku lililonse.
6.2 Yang'anani msoko wonse wowotcherera, dontho lakuwotcherera ndi malo okonzera.
6.3 Pambuyo kukhazikitsa, zochitika zina zazing'ono zimaloledwa.
6.4 Msoko wonse wowotcherera wowotchera uyenera kudutsa mayeso owononga, mayesowo ali ngati: kutengera makina omata kuti azidula ndi kusenda, zinthu zoyambira zidawonongeka pomwe kuwotcherera sikuloledwa kuwonongedwa.
6.5 Kuzindikira kuthamanga kwa mpweya: Mukamagwiritsa ntchito makina owotcherera njanji yamtundu wapawiri, mpweya umasungidwa pakati pa chowotcherera, ndipo zida zoyezera kuthamanga kwa mpweya ziyenera kugwiritsidwa ntchito kuzindikira mphamvu ndi kulimba kwa mpweya.Pambuyo pomanga weld, nsonga zonse ziwiri za weld zimasindikizidwa, ndipo chipinda cha mpweya cha weld chimakanikizidwa mpaka 250 kPa ndi chipangizo chowunikira mpweya kwa mphindi 3-5, kuthamanga kwa mpweya sikuyenera kutsika kuposa 240 kPa. Ndiyeno kumapeto kwina kwa weld, pamene kutsegula kwatsekedwa, barometer pointer ikhoza kubwezeredwa mwamsanga ku mbali ya ziro monga yoyenerera.
7. Konzani HDPE geomembrane
Panthawi yoyika, zolakwika zilizonse kapena kuwonongeka kwa geomembrane ziyenera kukonzedwa kuti zisakhudzidwe ndi ntchito yopanda madzi.
7.1 dzenje Small akhoza kukonzedwa ndi kuwotcherera extrusion, ngati dzenje ndi lalikulu kuposa 6mm, tiyenera chigamba zakuthupi.
7.2 Malo otsetsereka amayenera kukhala ndi zigamba, ngati mapeto a mzerewo ndi akuthwa, tidzadula mozungulira tisanamenye.
7.3 Geomembrane iyenera kupukutidwa ndi kuyeretsedwa musanamete.
7.4 Chigambacho chiyenera kukhala chofanana ndi chomaliza ndikudulidwa kukhala chozungulira kapena ellipse.Chigambacho chiyenera kukhala chachikulu kuposa malire a chilema osachepera 15cm.
8. HDPE Geomembrane nangula
Anchorage poyambira (kukula: 40cm * 40cm * 40cm), kokerani geomembrane mu poyambira ndi U wakuthwa ndikuikonza ndi thumba la mchenga kapena konkire.
9. Muyeso wodzitchinjiriza
Kuteteza HDPE geomembrane, tidzatengera njira zotsatirazi:
9.1 Pangani geotextile ina pamwamba pa geomembrane kenako konza mchenga kapena dothi.
9.2 Pambulani dothi kapena konkire ndikukongoletsa.
Ife, Shanghai Yingfan Engineering Material Co., LTD, tili ndi gulu lathu laukadaulo la unsembe kuti tipereke ntchito zoika pamalopo, ndi zaka zopitilira khumi.
