Geotextilesyog cov ntaub ntawv permeable uas, thaum siv hauv kev koom nrog hauv av, muaj peev xwm sib cais, lim, txhawb zog, tiv thaiv, los yog ntws.Feem ntau ua los ntawm polypropylene los yog polyester, geotextile fabrics tuaj nyob rau hauv peb cov ntaub ntawv yooj yim: woven (zoo li lub hnab xa ntawv sacking), koob punched (zoo li xav), los yog kub bonded (zoo li ironed xav).
Geotextile composites tau qhia thiab cov khoom xws li geogrids thiab meshes tau tsim.Geotextiles yog qhov ruaj khov, thiab tuaj yeem ua rau lub caij nplooj zeeg yog tias ib tug neeg poob.Zuag qhia tag nrho, cov ntaub ntawv no raug xa mus rau geosynthetics thiab txhua qhov kev teeb tsa - geonets, geosynthetic av nplaum liners, geogrids, geotextile raj, thiab lwm yam - tuaj yeem tau txais txiaj ntsig hauv geotechnical thiab ib puag ncig engineering tsim.
Keeb kwm
Nrog geotextile fabrics tau siv feem ntau ntawm cov chaw ua haujlwm niaj hnub no, nws nyuaj rau ntseeg tias cov thev naus laus zis no tsis muaj nyob rau yim xyoo dhau los.Cov tshuab no feem ntau yog siv los cais cov txheej hauv av, thiab tau dhau los ua kev lag luam ntau txhiab daus las.
Geotextiles yog Ameslikas tsim los ua lwm txoj hauv kev lim dej granular.Thawj, thiab tseem qee zaum siv, lo lus rau geotextiles yog lim ntaub.Ua hauj lwm pib thaum xyoo 1950 nrog RJ Barrett siv geotextiles qab precast pob zeb seawalls, nyob rau hauv precast qhob yaig tswj thaiv, hauv qab pob zeb loj riprap, thiab lwm yam kev tiv thaiv yaig.Nws siv cov qauv sib txawv ntawm woven monofilament fabrics, txhua tus yam ntxwv los ntawm qhov feem pua ntawm qhov chaw qhib (vim li ntawm 6 txog 30%).Nws tau tham txog qhov xav tau rau ob qho tib si txaus permeability thiab av khaws cia, nrog rau cov ntaub tsim nyog lub zog thiab elongation kom raug thiab teeb tsa lub suab rau geotextile siv hauv cov xwm txheej pom.
Daim ntawv thov
Geotextiles thiab cov khoom muaj feem xyuam muaj ntau daim ntawv thov thiab tam sim no txhawb nqa ntau yam kev siv engineering xws li txoj kev, airfields, railroads, embankments, retaining structures, reservoirs, canals, dams, bank protection, coastal engineering and construction site silt fences or geotube.
Feem ntau geotextiles muab tso rau ntawm qhov nro saum npoo kom ntxiv dag zog rau cov av.Geotextiles kuj tseem siv rau cov xuab zeb dune armoring los tiv thaiv thaj tsam ntawm ntug dej hiav txwv los ntawm cua daj cua dub, yoj ua haujlwm thiab dej nyab.Lub thawv ntim xuab zeb loj (SFC) nyob rau hauv lub dune system tiv thaiv cua daj cua dub los ntawm kev mus dhau ntawm SFC.Kev siv ib qho chaw sloped es tsis yog ib lub raj tshem tawm kev puas tsuaj.
Erosion tswj phau ntawv qhia txog qhov ua tau zoo ntawm txoj kab nqes, cov duab kauj ruam hauv kev txo cov shoreline yaig puas los ntawm cua daj cua dub.Geotextile sand-filled units muab "mos" armoring tov rau kev tiv thaiv cov cuab yeej upland.Geotextiles yog siv los ua matting kom stabilize ntws hauv kwj raws thiab swales.
Geotextiles tuaj yeem txhim kho av lub zog ntawm tus nqi qis dua li cov pa hauv av nailing. Ntxiv rau, geotextiles tso cai cog rau ntawm qhov chaw siab tshaj, ntxiv kev ruaj ntseg rau txoj kab nqes.
Geotextiles tau siv los tiv thaiv fossil hominid hneev taw ntawm Laetoli hauv Tanzania los ntawm kev yaig, nag, thiab tsob ntoo hauv paus.
Nyob rau hauv lub tsev demolition, geotextile fabrics ua ke nrog steel hlau fencing tuaj yeem muaj cov khoom tawg.
