HDPE geomembraneinozivikanwawo seyepamusoro-density polyethylene isingapindike geomembrane.Imhando yezvinhu zvisingapindi mvura, iyo mbishi ndeyepamusoro-molecular polymer.Zvikamu zvikuru i97.5% yeHDPE uye 2.5% yeCarbon dema/anti-aging agent/anti-oxygen/UV absorbent/stabilizer and other accessory.
Iyo inogadzirwa kuburikidza nekatatu co-extrusion tekinoroji neyepamberi otomatiki michina inotengeswa kubva kuItari.
Yingfan geomembranes ese anosangana kana kudarika US GRI uye ASTM zviyero.Basa rayo guru ndero-anti-seepage uye kuparadzaniswa., saka kuiswa kweHDPE geomembrane linerkunokosha zvikuru.
HDPE geomembrane yekumisikidza maitiro inoita basa rakakosha mumapurojekiti ekudzivirira mvura uye anopokana.Isu, Shanghai Yingfan Engineering Material Co., LTD, tine yedu tega nyanzvi yekuisa timu yekupa onsite yekuisa masevhisi, ine anopfuura makore gumi ezviitiko.Saka ndinovimba gwara iri rinogona kukubatsira chaizvo.
Gwaro iri rinosuma nzira yekuisa HDPE geomembrane.Kuburikidza negwaro iri, iwe unozoziva zvirinani kuisa HDPE geomembrane uye kukubatsira kuchengetedza nguva nebasa.
Kazhinji kutaura, HDPE geomembrane yekuisa maitiro sezvinotevera:
1) Kugadzirira kuiswa
2) Pa-site kurapwa
3) Kugadzirira kuisa HDPE geomembrane
4) Kuisa HDPE geomembrane
5) Welding HDPE geomembrane
6) Kuongorora kwehutano
7) Gadzirisa HDPE geomembrane
8) HDPE Geomembrane anchorage
9) Chiyero chekudzivirira
Rega ndiunze maitiro ekuisa iyo geomembrane zvakadzama pazasi:
1. Kugadzirira kuiswa
1.1 Gadzirira nzvimbo yakati sandara yakatenderedza saiti (saizi: yakakura kupfuura 8m * 10m) yekuburitsa zvinhu uye kucheka.
1.2 Bvisa geomembrane zvakanyatsonaka.Isa imwe bhodhi yehuni kumucheto kwerori uye bvisa geomembrane kubva murori kuburikidza nemaoko kana muchina.
1.3 Vhara membrane neimwe kavha isingapinde mvura, pazasi pepedhi isina chinhu.
2. Pa-site kurapwa
2.1 Chigadziko chekuisa chinofanira kuva chakasimba uye chakati sandara.Panofanira kunge pasina midzi, marara, matombo, zvimedu zvekongiri, simbi mbariro, girazi shards, nezvimwewo zvinogona kukuvadza HDPE geomembrane.
2.2 Kunyangwe nechepasi nepadivi pamateru etangi, dzvanya pamusoro nemuchina nekuti tangi rinomira zvakanyanya mushure mekuvharirwa kwemvura. deformation yemadziro nekuda kwekumanikidzwa kwemvura.Nzvimbo yacho inofanirwa kudhindwa. Kana ichibvumidzwa, kongiri chimiro chinofanira kunge chiri nani. (Sezviri pazasi mufananidzo.)
2.3.Hollow out anchoring groove (saizi 40cm*40cm) yakatenderedza tangi remvura kuitira kugadzirisa HDPE geomembrane.
3. Peparation yekuisa HDPEgeomembrane
3.1 Iyo yepamusoro inofanira kusvika kune dhizaini uye yemhando inodiwa.
3.2 Hunhu hweHDPE geomembrane uye welding tsvimbo inofanira kusvika pakugadzirwa uye zvinodiwa zvemhando.
3.3 Vanhu vasina hukama havatenderwe kupinda panzvimbo yekuiswa.
3.4 Vese vanoisa vanofanirwa kupfeka pass neshangu izvo zvisina kukuvara kuHDPE geomembrane.Hapana kuputa munzvimbo yekuisa.
3.5 Zvishandiso zvose zvinofanira kubatwa zvinyoro. Zvishandiso zvinopisa hazvibvumirwi kubata HDPE geomembrane.
3.6 Tora matanho ekudzivirira kuisa HDPE geomembrane.
3.7 Hatigoni kushandisa zvishandiso zvinogona kukonzera kukanganisa kwemagetsi panguva yekuendesa.Nzira dzisingadzorwi dzekuwedzera hadzibvumirwi uye dzinobata nekuchenjerera.
4. Kuisa HDPE geomembrane
4.1 Vhura iyo HDPE geomembrane panzvimbo yakati sandara uye cheka zvinhu kune inodiwa chimiro.
4.2 Kukuvadzwa kwakaitwa nemunhu kunofanirwa kudzivirirwa panguva yekuisa. Iyo geomembrane inofanira kuiswa yakatsetseka uye kuderedza drape.Sarudza nzira yekuisa inonzwisisika kuderedza simba rekubatana.
4.3 Deformation yeHDPE geomembrane inofanira kusungirwa nezve 1% -4%.
4.4 Yese yakaongororwa HDPE geomembrane inofanirwa kudzvanywa nemasaga ejecha kana zvimwe zvinhu zvinorema kudzivirira geomembrane kuvhuvhuta nemhepo.
4.5 Kuvakwa kwekunze kwekuisa kweHDPE geomembrane kunofanirwa kunge kuri pamusoro pe5 °C, uye hakuna mvura kana chando chisina mamiriro ekunze pasi pemhepo ina.Paunenge uchiisa geomembrane, iyo weld seam inofanira kuderedzwa.Pasi pemamiriro ekuvimbisa kunaka, zvigadzirwa zvinofanirwa kuchengetedzwa zvakanyanya sezvinobvira, uye mhando inogona kuve nyore kuvimbiswa.
4.6 Kuyera: kuyera saizi yekucheka;
4.7 Kucheka: Kucheka zvinoenderana nehukuru chaihwo hunodiwa;upamhi hwemakumbo ndeye 10cm ~ 15cm.
5. Welding HDPE geomembrane
5.1 Mamiriro ekunze:
(1) Tembiricha:4-40℃
(2) Kuoma mamiriro, hapana mvura kana imwe mvura
(3) Mhepo inomhanya ≤4 kirasi / h
5.2 Kupisa welding:
5.2.1 Iwo maviri HDPE geomembrane anofanira kupindirana zvishoma ne 15cm. Iyo membrane inofanira kugadziriswa uye kuderedza drape.
5.2.2 Nzvimbo yewelding inofanira kucheneswa uye kuona kuti hapana mvura, huruva kana zvimwe zvakasiyana.
5.2.3 Trial welding: Test welding inofanira kuitwa basa rekushongedza risati raitwa.Muedzo welding uchaitwa pane sampuli yezvinhu zvisingapindire zvakapihwa.Kureba kwemuenzaniso hakufaniri kuva pasi pe1 m uye hupamhi hahufaniri kuva pasi pe 0.2 m.Mushure mekunge bvunzo yewelding yapedzwa, matatu 2.5 cm yakafara zvidimbu zvimedu zvakachekwa kuyedza kusimba kwekubvarura uye kusimba kweweld shear.
5.2.4 Welding: Iyo geomembrane yakasungwa uchishandisa otomatiki inokambaira mhando mbiri njanji welding muchina.Iyo extrusion inopisa-yakanyungudika welder ichashandiswa uko kaviri njanji welding muchina haugone kushanda.Iyo inofananidzwa netsvimbo yewelding yezvinhu zvakafanana ne geomembrane.Iyo welding process ndeiyi: kugadzirisa kudzvanywa, kuseta tembiricha, kuseta kukurumidza, majoini ekuongorora, geomembrane kurodha mumushini, tanga mota.Panenge pasina mafuta kana mafuta. guruva pamajoini, uye hapazovi nemarara, condensation, unyoro uye mamwe marara mumakumbo akabatana pamusoro peiyo geomembrane.Inofanira kucheneswa pamberi pewelding.
5.3 Extrusion welding;
(1) Iwo maviri HDPE geomembrane anofanirwa kuputirwa kanenge 7.5cm.Nzvimbo yewelding inofanirwa kucheneswa uye ive nechokwadi chekuti hapana mvura, guruva kana mamwe maturu.
(2) Kupisa kupisa hakugone kukuvadza iyo HDPE geomembrane.
(3) Welding tsvimbo inofanira kuva yakachena uye yakaoma.
Hot welding
Extrusion welding
Panguva yekugadzira welding, kudzivirira HDPE geomembrane kuvhuvhuta nemhepo, tichaisa uye weld panguva imwe chete. Usati wapinza, chenesa nzvimbo yewelding. Gumbo rewelding machine rinofanirawo kucheneswa. Rongedza parameter usati welding. Chengetedza welding machine ichishanda nayo. yunifomu kumhanya.Check welding musono mushure Kunyatsotonhodzwa.
6. Kuongorora kwehutano
6.1 Kuzviongorora: Tarisa uye kurekodha zuva rega rega.
6.2 Tarisa yese yewelding seam, welding dot uye nzvimbo yekugadzirisa.
6.3 Mushure mekuiswa, mamwe madiki bump phenomenon anotenderwa.
6.4 Yese inopisa welding seam inofanirwa kupfuura inoparadza bvunzo, bvunzo yakaita se: tora tensile muchina wekucheka uye kupepeta, iyo base zvinhu yakaparadzwa nepo welding seam isingatenderwe kuparadzwa.
6.5 Kuona kudzvanywa kwemhepo: Paunenge uchishandisa otomatiki yekukambaira mhando mbiri njanji welding muchina, mhepo yemhepo inochengeterwa pakati peiyo weld, uye mhepo yekuyedza dhizaini inofanirwa kushandiswa kuona kusimba uye kusimba kwemhepo.Mushure mekunge kuvakwa kwe weld kwapera, migumo yese ye weld cavity inovharwa, uye kamuri yemhepo ye weld inomanikidzwa kusvika 250 kPa ine gasi rekuona dhizaini kwemaminetsi 3-5, mhepo yemhepo haifanire kunge yakaderera kupfuura. 240 kPa. Uyezve kune imwe magumo eweld, kana kuvhurwa kwabviswa, barometer pointer inogona kukurumidza kudzoserwa kudivi raziro sekukodzera.
7. Gadzirisa HDPE geomembrane
Munguva yekuisa maitiro, chero hurema kana kuparadzwa geomembrane inofanirwa kugadziriswa kudzivirira kupesvedzera kune basa rekusapinda mvura.
7.1 Gomba diki rinogona kugadziriswa neextrusion welding, kana gomba rakakura kupfuura 6mm, isu tinofanirwa kubatanidza zvinhu.
7.2 Chikamu chemutsetse chinofanirwa kuvharwa, kana magumo emutsetse akapinza, tinoicheka kuita denderedzwa tisati tabvisa.
7.3 Geomembrane inofanira kukuyiwa uye kucheneswa isati yaiswa mitsetse.
7.4 Chigamba chinofanirwa kunge chakafanana nechigadzirwa chekupedzisira uye chakachekwa kuita denderedzwa kana kuti ellipse.Chigamba chinofanirwa kunge chakakura kupfuura muganhu wekuremara zvinosvika 15cm.
8. HDPE Geomembrane anchorage
Anchorage groove (saizi:40cm*40cm*40cm), dhonza geomembrane mugoronga neU inopinza woigadzirisa nesaga rejecha kana kongiri.
9. Chiyero chekudzivirira
Kuchengetedza iyo HDPE geomembrane, isu tinotora pazasi nzira:
9.1 Pevera imwe geotextile kumusoro kwegeomembrane wobva wagadzira jecha kana ivhu.
9.2 Pave ivhu kana kongiri uye shongedza.
Isu, Shanghai Yingfan Engineering Material Co., LTD, tine yedu pachedu yekugadzwa timu yekupa onsite yekuisa masevhisi, ane anopfuura makore gumi experiences.Welcome kutibata nesu kuti uwane rumwe ruzivo nezve HDPE geomembrane zvigadzirwa uye yekuisa basa.
