Mushure mokunge nhamba huru yezviitiko zvemvura, zvinogumiswa kuti nekuiisa pasi pechidziva, mvura iri mudziva inoparadzaniswa nevhu kuti iwane chinangwa chekudzivirira mvura. Ndiyo mhinduro yakanakira kushandisa yakakwirira-simba polyethylene HDPE geomembrane seyakadzika jira redziva kudzivirira kubuda.
Tekinoroji yekugadzira yeHDPE geomembrane yakatyora musimboti wemachira, uye inoshandisa ruzivo rwemazuva ano rwesainzi. Maitiro ayo ekugadzirisa ndeyekuronga zvisina tsarukano machira mapfupi mafirita kana filaments kuti igadzire fiber mesh chimiro.
Panguva yekuiswa kweHDPE geomembrane, makwinya ekugadzira anofanirwa kudzivirirwa zvakanyanya sezvinobvira. Kana uchiisa HDPE geomembrane, kuwedzera uye kuderera kwehuwandu hunokonzerwa nekushanduka kwekushisa kunofanirwa kuchengetedzwa zvichienderana nekuchinja kwekushisa kwenzvimbo uye zvinodiwa zvekushanda kweHDPE geomembrane. Uye zvakare, iyo yekuwedzera uye chibvumirano huwandu hweiyo geomembrane inofanirwa kuchengetedzwa zvinoenderana nenzvimbo yenzvimbo uye geomembrane yekuisa mamiriro. Kugadzirisa kune kusaenzana kwekugadzirisa kwenheyo.
Iyo yekuisa uye welding kuvaka kweHDPE geomembrane kunofanirwa kuitwa kana tembiricha iri pamusoro pe5 ℃, simba remhepo riri pazasi pedanho 4, uye pasina mvura kana chando. Iyo hdpe geomembrane yekuvaka maitiro inoitwa nenzira inotevera: geomembrane kuisa → kubatanidza welding seams → welding → on-site yekuongorora → kugadzirisa → kuongorora zvakare → kudzosera kumashure. Kupindirana kwehupamhi hwemajoini pakati pe membranes haafanire kunge ari pasi pe80 mm. Kazhinji, kurongeka kwekuronga kunofanirwa kuenzana nehupamhi hwemateru mutsetse, ndiko kuti, kurongeka pamwe negwara remateru.
Mushure mokunge hdpe geomembrane yaiswa, kufamba pamusoro pe membrane, kutakura zvishandiso, nezvimwewo zvinofanira kuderedzwa. Zvinhu zvinogona kukonzera kukuvadza kune hdpe geomembrane hazvifanirwe kuiswa pa geomembrane kana kutakurwa uchifamba pa geomembrane kudzivirira kukuvadza hdpe membrane. kukonzera kukanganisa kwetsaona. Vese vashandi vari paHDPE membrane saiti yekuvaka havabvumidzwe kuputa, havabvumidzwe kupfeka shangu dzine mbambo kana shangu dzakasimba dzakasimba-heeled kufamba pamusoro pe membrane, uye havabvumidzwe kuita chero zviitiko zvinogona kukanganisa anti-seepage membrane.
Mushure mokunge hdpe geomembrane yaiswa, isati yafukidzwa nevhavha yekudzivirira, 20-40kg sandbag inofanira kuiswa yega 2-5m pamakona e membrane kudzivirira geomembrane kubva kumhepo. HDPE geomembrane anchorage inofanirwa kuvakwa zvinoenderana nedhizaini. Munzvimbo dzine nzvimbo dzakaoma mupurojekiti, kana chikwata chekuvaka chichikurudzira dzimwe nzira dzekumisa, inofanira kuwana kubvumirwa kwechikwata chekugadzira uye chikwata chekutarisa chisati chaenderera mberi.
Basa remubatanidzwa geomembrane muinjiniya yemumugwagwa ine durability chengetedzo
1. Basa remubatanidzwa geomembrane mukugadzira migwagwa
1. Kuzviparadzanisa nevamwe
Kuisa geomembrane inoumbwa pakati pezvinhu zviviri zvakasiyana, pakati pemadhayamita ezviyo akasiyana echinhu chimwe chete, kana pakati pevhu uye superstructure inogona kuitsaura. Kana iyo nzira yemugwagwa iri pasi pemitoro yekunze, kunyangwe iyo inosanganiswa geomembrane inotsikirirwa kune imwe neimwe pasi pekumanikidza, asi nekuti iyo inoumbwa geomembrane yakaparadzaniswa nepakati, haina kusanganisa kana kudonhedza pamwe chete, uye inogona kuchengetedza iyo yakazara. magadzirirwo uye kushanda kwenzira yenzira. Inoshandiswa zvakanyanya munjanji, migwagwa mikuru, mapurojekiti edhamu repasi-dombo, ivhu rakapfava Basic processing uye mamwe mapurojekiti.
2. Kudzivirira maitiro
Composite geomembrane inogona kuita basa mukuparadzira kushushikana. Kana simba rekunze richiendeswa kubva kune chimwe chinhu kuenda kune chimwe, rinogona kuodza kushushikana uye kudzivirira ivhu kuti risakuvadzwe nekunze kwesimba, nekudaro ichidzivirira nzira yenzira. Basa rekudzivirira reiyo composite geomembrane inonyanya kuchengetedza mukati mekubatana kwepamusoro, ndiko kuti, iyo composite geomembrane inoiswa pakati pezvinhu zviviri pamusoro penzira yepasi. Kana chimwe chinhu chiri pasi pekunetseka kwakanyanya, chimwe chacho hachizokuvadzwa.
3. Kusimbisa mhedzisiro
Iyo composite geomembrane ine yakakwira tensile simba. Kana yakavigwa muvhu kana panzvimbo yakakodzera mune yakarongwa dhizaini, inogona kugovera kushushikana kwevhu kana pavement chimiro, kutamisa kushushikana kwesimba, kudzikisira kusimuka kwayo kwekupedzisira, uye kuwedzera kubatana kwayo nevhu kana mugwagwa. Iko kupokana pakati pezvimiro zvezvimiro zvemukati kunowedzera kusimba kwevhu kana pavement structural layer uye geosynthetic material composite, zvichibva zvadzora chimiro chevhu kana pavement structural layer, kuvharidzira kana kudzikisa kugadzikana kwevhu, nekuvandudza kunaka kwevhu. Kana kugadzikana kwepavement structural layer ine basa rekusimbisa.
Kunyangwe akaumbwa geomembranes achitamba mabasa mazhinji mumapurojekiti emumugwagwa, anotamba akasiyana ekutanga uye echipiri mabasa munzvimbo dzakasiyana dzeprojekiti. Semuyenzaniso, kana uchiisa pakati peguva base layer uye hwaro hwenzira huru, basa rekuzviparadzanisa nevamwe rinowanzova iro guru, uye kudzivirira nekusimbisa ndekwechipiri. Paunenge uchivaka migwagwa panheyo dzisina simba, iyo inosimbisa mhedzisiro yeiyo composite geomembrane inogona kudzora ivhu.
