Mafuro mapfupi egeotextile nefuro refu egeotextile imhando mbiri dzemafuro anoshandiswa zvakanyanya muinjiniya yezvivakwa, uye ane musiyano mukushanda uye mashandisirwo awo. Chinyorwa chino chichatsanangura musiyano uripo pakati pefuro pfupi egeotextile nefuro refu egeotextile zvakadzama.
1. Zvinhu uye maitiro ekugadzira
Ma staple fiber geotextile anogadzirwa nema staple fiber polymers (akadai se polyester fibers) ane urefu hupfupi hwefiber, kazhinji pakati pemamirimita mashoma. Maitiro ekugadzira staple fiber geotextile ari nyore uye mutengo wakaderera, saka anoshandiswa zvakanyanya muinjiniya yezvivakwa.
Geotextile yefiber yakareba inogadzirwa nepolymer yefiber refu (polyester chip), uye urefu hwayo hwefiber hwakareba, kazhinji pakati pemakumi emamirimita. Maitiro ekugadzira mageotextile efiber refu akaoma uye anodhura, asi ane simba rakawanda uye anogara kwenguva refu.
2. Hunhu hwekushanda
1. Simba vs. Kugara kwenguva refu
Matanda marefu efiber geotextile ane simba rakawanda uye anogara kwenguva refu, uye anogona kutsungirira kumanikidzwa kukuru uye simba rekudhonza, saka anoshandiswa zvakanyanya muinjiniya yezvivakwa uko anoda kutakura mitoro mikuru. Zvisinei, simba uye kugara kwenguva refu kwestaple fiber geotextile kwakaderera, uye kwakakodzera hunyanzvi hwekugadzira zvezvivakwa.
2. Kupinda kwemvura
Staple fiber geotextile ine mvura yakakwana inoyerera zvakanaka, iyo inogona kuburitsa mvura nekukurumidza pamusoro pejira uye kuchengetedza ivhu rakaoma. Zvisinei, mvura inoyerera ye fiber refu geotextile haina kunaka, asi inogona kupinda nepachivako chidiki chiri pamusoro pejira.
3. Kusagona kushandisa makemikari
Geotextile refu ine ngura yakanaka yemakemikari uye inogona kuramba kukanganiswa neacids, alkalis nemamwe makemikari. Zvisinei, ngura yemakemikari ye staple fiber geotextiles haina kunaka, saka matanho ekudzivirira anoenderana nawo anofanira kutorwa.
4. Kudzivirira UV
Geotextile refu ine simba rakanaka rekudzivirira ultraviolet, iyo inogona kudzivirira kuputsika kwemwaranzi ye ultraviolet uye kuchengetedza simba uye kugara kwenguva refu kwejira. Zvisinei, simba rekudzivirira ultraviolet rema staple fiber geotextiles harina kunaka, saka matanho ekudzivirira anoenderana nawo anofanira kutorwa.
3. Minda yekushandisa
1. Uinjiniya hweHydraulic
Mumapurojekiti ekuchengetedza mvura, mageotextile mapfupi uye mageotextile marefu akashandiswa zvakanyanya. Mageotextile mapfupi anogona kushandiswa kusimbisa nekudzivirira mahombekombe erwizi, madhamu nezvimwe zvikamu, nepo mageotextile marefu anogona kushandiswa pakuvaka mapurojekiti makuru ekuchengetedza mvura akadai sematangi emvura nemadhamu.
2. Uinjiniya hwemigwagwa
Mukugadzira migwagwa, jira remachira mapfupi rinogona kushandiswa kusimbisa nekudzivirira pasi pevhu nemugwagwa, nepo jira remachira marefu rinogona kushandiswa pakuvaka migwagwa mikuru, njanji nedzimwe nzira dzekutakura zvinhu.
3. Uinjiniya hweKuchengetedza Zvakatipoteredza
Mumapurojekiti ekuchengetedza nharaunda, ma "short-fiber geotextile" anogona kushandiswa mukuvaka mapurojekiti ekugadzirisa nharaunda akadai sekugadzirisa ivhu uye kurasira marara, nepo ma "long-fiber geotextile" anogona kushandiswa mukuvaka mapurojekiti ekuchengetedza nharaunda akadai sekuchenesa tsvina yetsvina uye kugadzirisa mvura.
Muchidimbu, pane musiyano uri pachena pakati pema "short-fiber geotextile" nema "long-fiber geotextile" muzvinhu, maitiro ekugadzira, maitiro ekushanda uye minda yekushandisa. Muinjiniya yezvivakwa, mhando yakakodzera ye "geotextile" inofanira kusarudzwa zvichienderana nezvinodiwa chaizvo nemamiriro chaiwo ezvinhu.
