Kumanga kwa geotextile komwe kumagwiritsidwa ntchito ndi singano ya geotextile yomwe imakhomeredwa ndi nonwoven

Geotextilesndi nsalu zotha kulowa mkati zomwe zikagwiritsidwa ntchito limodzi ndi dothi zimatha kupatukana, kusefa, kulimbikitsa, kuteteza, kapena kukhetsa.Zopangidwa kuchokera ku polypropylene kapena poliyesitala, nsalu za geotextile zimabwera m'njira zitatu: zoluka (zofanana ndi thumba la makalata), singano yokhomeredwa (yofanana ndi kumverera), kapena yomangika (yofanana ndi chitsulo).

Ma composites a geotextile adayambitsidwa ndipo zinthu monga ma geogrids ndi ma meshes apangidwa.Ma geotextiles ndi olimba, ndipo amatha kufewetsa kugwa ngati wina agwa.Ponseponse, zidazi zimatchedwa geosynthetics ndipo kasinthidwe kalikonse - ma geonets, ma geosynthetic dongo, ma geogrids, machubu a geotextile, ndi ena - amatha kupindula pamapangidwe a geotechnical ndi chilengedwe.

Mbiri

Ndi nsalu za geotextile zomwe zimagwiritsidwa ntchito nthawi zambiri pamalo ogwirira ntchito masiku ano, ndizovuta kukhulupirira kuti ukadaulo uwu sunakhaleko zaka makumi asanu ndi atatu zapitazo.Ukadaulo umenewu umagwiritsidwa ntchito mowirikiza kulekanitsa zigawo za dothi, ndipo wasanduka bizinesi ya mabiliyoni ambiri.

Ma geotextiles poyambirira adapangidwa kuti akhale m'malo mwa zosefera za granular.Choyambirira, ndipo nthawi zina chimagwiritsidwa ntchito, mawu oti geotextiles ndi nsalu zosefera.Ntchito idayamba mzaka za m'ma 1950 ndi RJ Barrett pogwiritsa ntchito ma geotextiles kuseri kwa mipanda ya konkriti yokhazikika, pansi pa midadada yoletsa kukokoloka kwa konkriti, pansi pamiyala yayikulu, komanso nthawi zina zowongolera kukokoloka.Anagwiritsa ntchito masitayelo osiyanasiyana a nsalu zopangidwa ndi monofilament, zonse zodziwika ndi malo otseguka (osiyana 6 mpaka 30%).Anakambirana za kufunika kokwanira kokwanira komanso kusunga nthaka, komanso mphamvu yokwanira ya nsalu ndi elongation yoyenera ndikuyika kamvekedwe ka geotextile pakugwiritsa ntchito kusefa.

Mapulogalamu

Ma geotextiles ndi zinthu zina zofananira zili ndi ntchito zambiri ndipo pakadali pano zimathandizira ntchito zambiri zamaumisiri wamba kuphatikiza misewu, mabwalo a ndege, njanji, mipanda, zosungiramo, malo osungiramo madzi, ngalande, madamu, chitetezo chamabanki, uinjiniya wa m'mphepete mwa nyanja ndi mipanda ya silt kapena geotube.

Nthawi zambiri ma geotextiles amayikidwa pamtunda kuti alimbitse nthaka.Ma geotextiles amagwiritsidwanso ntchito popangira zida za mchenga kuti ateteze malo okwera m'mphepete mwa nyanja ku mvula yamkuntho, mafunde komanso kusefukira kwamadzi.Chidebe chachikulu chodzaza mchenga (SFC) mkati mwaduna chimalepheretsa kukokoloka kwa mkuntho kupitilira SFC.Kugwiritsa ntchito motsetsereka m'malo mogwiritsa ntchito chubu limodzi kumachotsa zowononga.

Mabuku oletsa kukokoloka akufotokoza za mphamvu ya zinthu zotsetsereka, zopondapo pochepetsa kuonongeka kwa gombe ndi mphepo yamkuntho.Magawo odzaza mchenga wa geotextile amapereka yankho "lofewa" lachitetezo chachitetezo chamtunda.Ma geotextiles amagwiritsidwa ntchito ngati matting kuti akhazikitse kuyenda kwa mitsinje ndi mitsinje.

Ma geotextiles amatha kukulitsa mphamvu ya nthaka pamtengo wotsika kuposa kukhomerera nthaka wamba.Kuphatikiza apo, ma geotextiles amalola kubzala pamapiri otsetsereka, kuteteza malo otsetsereka.

Geotextiles akhala akugwiritsidwa ntchito kuteteza mapazi a Laetoli ku Tanzania kuti asakokoloke, mvula, ndi mizu yamitengo.

Pakugwetsa nyumba, nsalu za geotextile zophatikizana ndi mpanda wa waya wachitsulo zimatha kukhala ndi zinyalala zophulika.
