Ma geotextile a ulusi waufupi ndi ma geotextile a ulusi wautali ndi mitundu iwiri ya ma geotextile omwe amagwiritsidwa ntchito kwambiri muuinjiniya wa zomangamanga, ndipo ali ndi kusiyana pang'ono pa magwiridwe antchito ndi kagwiritsidwe ntchito. Nkhaniyi ifotokoza mwatsatanetsatane kusiyana pakati pa geotextile ya ulusi waufupi ndi geotextile ya ulusi wautali.
1. Zipangizo ndi njira zopangira
Ma geotextile a ulusi wokhazikika amapangidwa ndi ma polima a ulusi wokhazikika (monga ulusi wa polyester) okhala ndi ulusi waufupi, nthawi zambiri pakati pa mamilimita angapo. Njira yopangira ulusi wokhazikika wa geotextile ndi yosavuta ndipo mtengo wake ndi wotsika, kotero imagwiritsidwa ntchito kwambiri muuinjiniya wa zomangamanga.
Geotextile ya ulusi wautali imapangidwa ndi polymer ya ulusi wautali (polyester chip), ndipo ulusi wake ndi wautali, nthawi zambiri pakati pa mamilimita makumi. Njira yopangira ma geotextile a ulusi wautali ndi yovuta komanso yokwera mtengo, koma imakhala ndi mphamvu komanso kulimba kwambiri.
2. Makhalidwe a ntchito
1. Mphamvu vs. Kukhalitsa
Ma geotextile a ulusi wautali ali ndi mphamvu komanso kulimba kwambiri, ndipo amatha kupirira kupsinjika kwakukulu komanso mphamvu zokoka, kotero amagwiritsidwa ntchito kwambiri mu uinjiniya wa zomangamanga komwe amafunika kunyamula katundu wokulirapo. Komabe, mphamvu ndi kulimba kwa geotextile ya ulusi wofunikira ndizochepa, ndipo ndi yoyenera uinjiniya wamba.
2. Kulowa kwa madzi
Staple fiber geotextile ili ndi madzi okwanira, omwe amatha kutulutsa madzi mwachangu pamwamba pa nsalu ndikusunga nthaka youma. Komabe, madzi okwanira a fiber geotextile yayitali ndi ochepa, koma amatha kulowa kudzera mu kapangidwe ka microporous pamwamba pa nsalu.
3. Kukana mankhwala
Ulusi wautali wa geotextile uli ndi kukana dzimbiri kwa mankhwala ndipo umatha kulimbana ndi kuwonongeka kwa ma asidi, alkali ndi mankhwala ena. Komabe, kukana dzimbiri kwa mankhwala a ulusi wofunikira wa geotextile ndi kochepa, kotero njira zodzitetezera ziyenera kutengedwa.
4. Kukana kwa UV
Ulusi wautali wa geotextile uli ndi kukana bwino kwa ultraviolet, komwe kumatha kukana kuwonongeka kwa kuwala kwa ultraviolet ndikusunga mphamvu ndi kulimba kwa nsalu. Komabe, kukana kwa ultraviolet kwa ulusi wofunikira wa geotextile ndi kochepa, kotero njira zodzitetezera ziyenera kutengedwa.
3. Magawo ogwiritsira ntchito
1. Uinjiniya wamadzimadzi
Mu mapulojekiti osamalira madzi, ma geotextile afupiafupi ndi ma geotextile aatali akhala akugwiritsidwa ntchito kwambiri. Ma geotextile afupiafupi angagwiritsidwe ntchito polimbitsa ndi kuteteza magombe a mitsinje, madamu ndi zigawo zina, pomwe ma geotextile aatali angagwiritsidwe ntchito pomanga mapulojekiti akuluakulu osamalira madzi monga malo osungiramo madzi ndi madamu.
2. Uinjiniya wa misewu
Mu uinjiniya wa misewu, geotextile yaufupi ingagwiritsidwe ntchito polimbitsa ndi kuteteza pansi pa nthaka ndi panjira, pomwe geotextile yautali ingagwiritsidwe ntchito pomanga misewu ikuluikulu, njanji ndi mizere ina ya magalimoto.
3. Uinjiniya Woteteza Zachilengedwe
Mu mapulojekiti oteteza chilengedwe, ma geotextile afupiafupi angagwiritsidwe ntchito pomanga mapulojekiti osamalira chilengedwe monga kukonza nthaka ndi malo otayira zinyalala, pomwe ma geotextile aatali angagwiritsidwe ntchito pomanga mapulojekiti oteteza chilengedwe monga kukonza zinyalala ndi kuyeretsa madzi.
Mwachidule, pali kusiyana koonekeratu pakati pa ma geotextiles afupiafupi ndi ma geotextiles aataliatali pa zipangizo, njira zopangira, makhalidwe a ntchito ndi malo ogwiritsira ntchito. Mu uinjiniya wa zomangamanga, mtundu woyenera wa geotextiles uyenera kusankhidwa malinga ndi zosowa zenizeni komanso mikhalidwe yeniyeni.
