I-geotextile yokuhambisa amanzi
Inkcazo emfutshane:
-
- I-drainage geotextile luhlobo lwezinto ze-geosynthetic, ezisetyenziswa kakhulu kwiinkqubo zokukhupha amanzi zobunjineli bokwakha kunye nobunjineli be-geotechnical. Ingakhupha amanzi ngokufanelekileyo emhlabeni kwaye ikwadlala indima yokuhluza kunye nokwahlulahlula. Sisixhobo sobunjineli esisebenza ngeendlela ezininzi.

- Umgaqo wokukhupha amanzi
- Ukukhupha amanzi kwi-geotextile yokukhupha amanzi kusekelwe kakhulu kwisakhiwo sayo se-pore kunye nokuvuleka kwamanzi. Kukho ii-pore ezininzi ezincinci ngaphakathi kuyo, kwaye ezi pores zidibene ukuze zenze uthungelwano oluntsonkothileyo lwemijelo yokukhupha amanzi.
- Xa kukho amanzi emhlabeni, phantsi kwempembelelo yomxhuzulane okanye umahluko woxinzelelo (njengoxinzelelo lwe-hydrostatic, uxinzelelo lokuvuza kwamanzi, njl.njl.), amanzi aya kungena ngaphakathi kwe-geotextile ngeembobo ze-geotextile. Emva koko, amanzi ahamba ngemijelo yokukhupha amanzi ngaphakathi kwe-geotextile aze ekugqibeleni akhokelwe kwindawo yokuphuma kwenkqubo yokukhupha amanzi, njengemibhobho yokukhupha amanzi, imibhobho yokukhupha amanzi, njl.njl.
- Umzekelo, kwinkqubo yokukhupha amanzi angaphantsi komhlaba, amanzi angaphantsi komhlaba angena kwi-drainage geotextile phantsi kwesenzo somahluko woxinzelelo, aze amanzi athuthwe aye kwimibhobho yokukhupha amanzi esecaleni kwendlela nge-geotextile, ngaloo ndlela efezekisa ukukhutshelwa kwamanzi angaphantsi komhlaba.
- Iimpawu zokusebenza
- Ukusebenza koMsele woMbane
- I-geotextile yokukhupha amanzi inesantya esiphezulu sokukhupha amanzi kwaye ingakhupha amanzi ngokukhawuleza. Isantya sayo sokukhupha amanzi sidla ngokulinganiswa yi-coefficient yokukhupha amanzi. Okukhona i-coefficient yokukhupha amanzi inkulu, kokukhona isantya sokukhupha amanzi sikhawuleza. Ngokubanzi, i-coefficient yokukhupha amanzi ye-geotextile yokukhupha amanzi inokufikelela kumlinganiselo wobukhulu be-10⁻² - 10⁻³ cm/s, nto leyo eyenza ukuba ikwazi ukuhlangabezana neemfuno ezahlukeneyo zokukhupha amanzi.
- Ingagcina ukusebenza kakuhle kokukhupha amanzi phantsi koxinzelelo oluthile. Umzekelo, xa udonga lwendlela luphantsi komthwalo wesithuthi, i-drainage geotextile isenokukhupha amanzi ngendlela eqhelekileyo kwaye ayiyi kuvala imijelo yokukhupha amanzi ngenxa yoxinzelelo.
- Ukusebenza kokuhluza
- Ngethuba kutsalwa amanzi, i-drainage geotextile inokuyihluza ngempumelelo iingceba zomhlaba. Ingayithintela iingceba ezincinci (ezifana ne-silt, udongwe, njl.njl.) emhlabeni ukuba zingangeni kwimisele yokukhupha amanzi kwaye ithintele inkqubo yokukhupha amanzi ukuba ingavaleki. Ukusebenza kwayo kokucoca kufezekiswa ngokulawula ubungakanani be-pore kunye nolwakhiwo lwe-pore ye-geotextile.
- Ngokubanzi, ubungakanani bembobo elinganayo (O₉₅) busetyenziselwa ukulinganisa ukusebenza kokuhluza kwe-geotextile. Le parameter imele ixabiso eliphezulu le-95% yobubanzi bento enokuthi idlule kwi-geotextile. Ubungakanani bembobo elinganayo efanelekileyo bunokuqinisekisa ukuba kuphela ngamanzi nezinto ezinyibilikisiweyo emanzini ezinokudlula, ngelixa amasuntswana omhlaba ebanjwa.
- Iipropati zoomatshini
- I-geotextile yokukhupha amanzi inamandla athile okutsalwa kunye namandla okukrazula kwaye inokumelana nemiphumo yokutsalwa kunye nokukrazula ngexesha lenkqubo yokwakha. Amandla okutsalwa ngokubanzi aphakathi kwe-1 - 10 kN/m, nto leyo eyenza ukuba ingaqhekeki lula ngexesha lenkqubo yokubeka nokusetyenziswa.
- Ikwasebenza kakuhle ekulweni nokubhoboza kwaye inokumelana nokubhoboza xa idibana nezinto ezibukhali (ezifana namatye, iingcambu, njl.njl.) kwaye ithintele ukutshatyalaliswa kwemijelo yokukhupha amanzi.
- Ukuqina kunye nokumelana nokugqwala
- Ekubeni i-drainage geotextile idla ngokuchatshazelwa ziimeko ezahlukeneyo zendalo, ihlala ixesha elide. Iphantsi kwempembelelo yemitha ye-ultraviolet, utshintsho lobushushu, ukukhukuliseka kwezinto zeekhemikhali kunye nezinye izinto, isenako ukugcina ukusebenza kwayo.
- Iyakwazi ukumelana kakuhle nezinto zeekhemikhali ezifana ne-asidi kunye ne-alkali, kwaye ingasebenza ngokuqhelekileyo nokuba kumhlaba one-asidi okanye umhlaba one-alkali. Umzekelo, kwinkqubo yokukhupha amanzi phantsi komhlaba yepaki yemizi-mveliso yeekhemikhali, i-drainage geotextile inokumelana nokukhukuliseka kwamanzi amdaka eekhemikhali kwaye iqinisekise ukusebenza okuqhelekileyo kwenkqubo yokukhupha amanzi.
- Ukusebenza koMsele woMbane
- Imizekelo yesicelo
- Ubunjineli beNdlela noLoliwe
- Ngokuphathelele ukukhupha amanzi angaphantsi komhlaba, i-drainage geotextile inokubekwa ezantsi okanye kwithambeka le-subgrade ukuze kukhutshwe amanzi angaphantsi komhlaba kunye namanzi angaphezulu kwendlela. Oku kunceda ukuthintela ukukhupha amanzi angaphantsi komhlaba kwizifo ezibangelwa kukuqokelelwa kwamanzi, njengokugcwala kweqabaka kunye nokuncipha.
- Kwindlela zokulungisa iindonga ezigcina amanzi, i-drainage geotextile ingasetyenziswa njengomaleko wesihluzo kwaye ifakwe ngasemva kodonga olugcina amanzi ukuze kukhutshwe amanzi emva kodonga kwaye kuthintelwe ukulahleka kwamasuntswana omhlaba, ukuqinisekisa uzinzo lodonga olugcina amanzi.
- Ubunjineli boLondolozo lwaManzi
- Kwiinkqubo zangaphakathi zokukhupha amanzi kwizakhiwo zokugcina amanzi ezifana namadama kunye needike, i-drainage geotextile ingasetyenziselwa ukuthulula amanzi aphumayo ngaphakathi komzimba wedama okanye umzimba wedike, ukunciphisa uxinzelelo lwamanzi kunye nokuphucula uzinzo lwesakhiwo.
- Kwi-slope yomlambo - udonga lwe-slope - ubunjineli bokukhusela, i-drainage geotextile ingasetyenziswa njengesixhobo sokukhupha amanzi kunye nesihluzo sokukhupha amanzi aqokelelene kwi-slope body kunye nokuthintela umhlaba we-slope body ukuba ungakhukuliswa ngamanzi omlambo.
- Ubunjineli boKwakha
- Kwiinkqubo zokukhupha amanzi kunye nezokukhupha amanzi kwizakhiwo ezingaphantsi komhlaba, i-drainage geotextile ingasetyenziswa njengesixhobo sokuncedisa ukukhupha amanzi kunye nomaleko ongangeni manzi. Ingakhupha amanzi angaphantsi komhlaba ajikeleze i-basement kwaye ithintele i-basement ukuba ingafumi kwaye ikhukulise.
- Kwinjineli yokukhupha amanzi kwisiseko, i-drainage geotextile inokubekwa ezantsi kwesiseko ukuze kukhutshwe amanzi phantsi kwesiseko kwaye kuphuculwe imeko yoxinzelelo lwesiseko.
- Ubunjineli bokuLahla iNkunkuma
- Emazantsi nakwiindawo ezithe tyaba zeenkunkuma, i-drainage geotextile ingasetyenziselwa ukuqokelela nokukhuculula inkunkuma ephuma kwinkunkuma ebolayo. Oku kubaluleke kakhulu ekuthinteleni ukuvuza kwenkunkuma ephumayo nokukhusela okusingqongileyo.
- Ingasetyenziswa kunye nezinye izinto zobugcisa be-geotechnical (ezifana nee-geomembranes) ukwakha inkqubo yokukhupha amanzi edibeneyo kunye nenkqubo engangenisi amanzi kwiindawo zokulahla inkunkuma.
