Geosynthetics rudzi rutsva rwe geotechnical engineering zvinhu, zvinogona kugadzirwa nemapolymers echisikigo kana akaitwa nevanhu (plastiki, kemikari fiber, synthetic rubber, nezvimwewo) uye kuiswa mukati, pamusoro kana pakati pezvikamu zvakasiyana zvevhu kusimbisa kana kudzivirira iyo ivhu.
Parizvino, Geotextiles yakashandiswa zvakanyanya mumigwagwa, njanji, kuchengetedza mvura, simba remagetsi, kuvaka, zviteshi zvegungwa, migodhi, indasitiri yemauto, kuchengetedza kwezvakatipoteredza uye mamwe minda.Iwo makuru emhando dze geosynthetics anosanganisira geotextiles, geogrids, geogrids, geomembranes, geogrids, geo composites, bentonite mats, geological materu, geo foam, etc. Muinjiniya application, Geotextiles inogona kushandiswa yega kana musanganiswa ne geogrids, geomembranes nemamwe, geogrids geo composite zvinhu.
Parizvino, zvigadzirwa zve geotextiles zvinonyanya kugadzirwa, izvo zvinonyanya kushandiswa ndeye polyester fiber uye polypropylene fibers, inoteverwa ne polyamide fibers uye polyvinyl acetal fibers.
Polyester fiber ine yakanaka yemuviri uye mekiniki zvivakwa, kusimba kwakanyanya uye zvinokambaira zvivakwa, yakakwirira kunyungudika, yakakwirira tembiricha kuramba, kuramba kuchembera, tekinoroji yekugadzira yakakura uye musika wakakwira.Izvo zvisingabatsiri hydrophobicity yakashata, nyore kuunganidza condensate yemafuta ekudzivirira zvinhu, kuderera-kupisa kwekuita, nyore kuita vitrify, kuderedzwa simba, kuderera kweasidhi uye alkali kuramba.
Polypropylene faibha ine elasticity yakanaka, uye kunyungudika kwayo nekusimba kwayo kuri nani pane faibha yepolyester.Yakanaka asidhi uye alkali kuramba, kupfeka kuramba, mildew kuramba uye kushomeka kwekushisa;Iyo ine yakanaka hydrophobicity uye kunyura kwemvura, uye inogona kuendesa mvura kunzvimbo yekunze pamwe chete nefiber axis.Iyo density idiki, chete 66% yepolyester fiber.Mushure menguva zhinji dzekunyora, yakanaka denier fiber ine compact dhizaini uye yepamusoro mashandiro anogona kuwanikwa, uyezve mushure mekusimbisa maitiro, simba rayo rinogona kuwedzera.Izvo zvisingabatsiri ndeyekupisa kwekushisa kwepamusoro, kupfava kwe130 ~ 160 ℃, kushomeka kwechiedza, nyore kuora muzuva, asi zvinotora UV uye zvimwe zvinowedzera zvinogona kuwedzerwa kuti zviite kuti UV isarambe.
Pamusoro pemafibers ari pamusoro apa, jute fibers, polyethylene fibers, polylactic acid fibers, nezvimwewo zvinogona kushandiswawo sezvigadziriso zvenonwoven geotextiles.Mafibisi echisikigo uye akakosha fiber zvishoma nezvishoma akapinda munzvimbo dzakasiyana dzekushandisa dze geotextiles.Semuenzaniso, mashizha echisikigo (jute, coconut shell fiber, bamboo pulp fiber, nezvimwewo) akashandiswa mukudzikisa, mvura, kuchengetedzwa kwebhangi, kudzivirira kwevhu uye mamwe minda.
Mhando yeGeotextile
Geotextile imhando yeinopindika geotextile yakagadzirwa nepolymer fiber nekupisa kudzvanya, simende uye kurukwa, inozivikanwawo se geotextile, kusanganisira kuruka uye nonwovens.
Zvigadzirwa zvakarukwa zveGeotextile zvinosanganisira kuruka (plain weave, round weave), kuruka (plain weave, twill), kuruka (warp knitting, kuruka tsono) uye mamwe maitiro ekugadzira.
Nonwoven geotextiles anosanganisira maitiro ekugadzira akadai semechani yekusimbisa nzira (acupuncture nzira, nzira yekuboora mvura), makemikari bonding nzira (glue yekupfapfaidza nzira, impregnation nzira), inopisa kunyunguduka nzira yekubatanidza (inopisa yekutenderedza nzira, inopisa mweya nzira), nezvimwe.
Yakarukwa geotextile ndiyo yekutanga yakaunzwa geotextile, asi ine zvisingakwanisi kudhura zvakanyanya uye kusaita zvakanaka.Mukupera kwema1960s, asiri-yakarukwa geotextiles akaunzwa.Mukutanga kwema1980, China yakatanga kushandisa zvinyorwa izvi mumasangano einjiniya.Nekukurumbira kwetsono dzakaroverwa nonwovens uye spunbonded nonwovens, iyo nzvimbo yekushandiswa yenonwovens yakakura kupfuura iyo ye deformed geotextiles, uye yakagadzira nekukurumidza.China yakagadzira kuve mugadziri mukuru weNonwovens pasirese, uye zvishoma nezvishoma iri kuenda kune mugadziri ane simba.
Geotextile filtration, kudiridza, kuzviparadzanisa nevamwe, kusimbisa, kudzivirira, kudzivirira hutachiona, huremu huremu, kusimba kwepamusoro, kupinza kwakanaka uye kushomeka kwekushisa, kutonhora kwekudzivirira, kuchembera kuramba, kusimba, kushanduka uye zvichingodaro, zvinoshandiswa zvakanyanya munzvimbo dzakasiyana siyana.Hupenyu hweguta rebasa rakanakisa kwenguva pfupi hunoratidza zvachose kuti hapana imwe hutachiona.
Nei chaiyo accounting ichifanira kuitwa pamberi pekuvaka geotextile?Mazhinji manovice tekinoroji haana kunyatso kujeka nezve chaiyo accounting ye geotextiles isati yavakwa.Izvo zvinoenderana nekontrakiti yekuronga uye nzira yekuvaka quotation.Kazhinji, inoverengwa maererano nenzvimbo.Iwe unofanirwa kuterera kune yakatenuka.Iwe unofanirwa kuiwedzera nekatsetse kakatsetseka.
