Bungwe la American Society of Agriculture engineers limatchula ma geotextiles ngati deta ya geotextiles kapena geotechnical components pakati pa nthaka ndi mapaipi, ma gabions kapena makoma osungira.Deta iyi ikhoza kupititsa patsogolo kayendedwe ka madzi ndikulepheretsa kuyenda kwa nthaka.Geotextile, yomwe imadziwikanso kuti geotextile, ndi mtundu wansalu yotha kulowa mkati yopangidwa ndi zida za geotechnical.Amagwiritsidwa ntchito ngati dothi, miyala, nthaka kapena zida zina zaukadaulo wa geotechnical, komanso ngati gawo la uinjiniya wochita kupanga kuti akwaniritse mapangidwe ake.Zida za geotextile siziyenera kungoganizira zakuthupi ndi zamankhwala zomwe zimafunikira ndi malo ogwiritsira ntchito, komanso kulabadira mtengo wazinthu.
Geotextile ndi chida chodziwika bwino cha hydraulic conductivity
Madzi m'nthaka akatsuka zinthu zosanjikiza munthaka, singano yokhomeredwa ndi geotextile yokhala ndi permeability yabwino komanso permeability imagwiritsidwa ntchito kuti madziwo adutse ndikuteteza bwino kutuluka kwa tinthu tating'ono, ulusi, miyala yaying'ono, ndi zina zambiri. kuti zitsimikizire kukhazikika kwa uinjiniya wa madzi ndi nthaka.Kutulutsa kwamadzi kwa geotextile geotextile ndi mtundu wazinthu zabwino kwambiri zoyendetsera madzi.Ikhoza kupanga ngalande m'nthaka ndi kutulutsa mpweya wotsalira wamadzimadzi kunja kwa thupi.Kulimbitsa mphamvu ya geotextile singano yopangidwa ndi singano ya geotextile imagwiritsidwa ntchito kupititsa patsogolo kulimba kwamphamvu komanso kukana kusintha kwa nthaka, kukulitsa kukhazikika kwa zomangamanga, ndikuwongolera nthaka.
Njira yopangira filament geotextile ndi motere:
1. filament geotextile idzaikidwa ndi njira yopukutira pamanja, ndipo pamwamba pa nsaluyo padzakhala lathyathyathya ndi gawo loyenera lopindika;
2. makina osokera m'manja adzagwiritsidwa ntchito kusoka filament geotextile, ndipo nthawi ya ola idzayendetsedwa pafupifupi 6mm.Mphamvu zomangira za kumtunda kwa geotextile ndi maziko a geotextile siziyenera kuchepera 70% ya mphamvu ya geotextile yokha.
3. kusankha splicing njira filament geotextile, ndi splicing m'lifupi sadzakhala zosakwana 0.1 M;
4. nsonga zonse ziyenera kuchitidwa mosalekeza, ndipo palibe kusokera kwa mfundo kumaloledwa.Mtunda wocheperako wa singano ndi 2.50cm;
5. ulusi wogwiritsidwa ntchito kusoka udzakhala utomoni wokhala ndi mphamvu yocheperapo kuposa 60N, ndipo ukhale ndi kukana koyenera kapena kopitilira muyeso wa dzimbiri komanso kukana kwa radiation ya ultraviolet ya geotextile;
6. ngati kudumpha kwa singano ndi zochitika zina zosayenerera, kukonzanso kuyambira pachimake pa suture
