Inkcazelo emfutshane:
I-geotextiles ezingalukwanga zineengenelo ezininzi, ezinje ngokungena komoya, ukuhluzwa, ukugquma, ukufunxwa kwamanzi, ukungenwa manzi, ukurhoxiswa, ukuziva ulungile, uthambile, ulula, ulula, uyabuyiswa, akukho mkhombandlela welaphu, imveliso ephezulu, isantya semveliso kunye namaxabiso aphantsi. Ukongeza, ikwanawo amandla aphezulu okuzibamba kunye nokuxhathisa ukukrazula, i-drainage elungileyo ethe nkqo kunye nethe tyaba, ukubekwa yodwa, ukuzinza, ukuqinisa kunye neminye imisebenzi, kunye nokugqwesa okugqwesileyo kunye nokusebenza kokucoca.
IiNkcazo zeeMveliso
Ii-geotextiles ezingalukwanga zizinto ze-geosynthetic ezinokungena emanzini ezenziwe ngeentsinga zokwenziwa ngokulinaliti okanye ngokulukwa. Inokucoca okugqwesileyo, ukwahlukaniswa, ukomelezwa kunye nokhuseleko, ngelixa amandla aphezulu, ukunyanzeliswa okulungileyo, ukumelana nobushushu obuphezulu, ukumelana nomkhenkce, ukumelana nokuguga, ukuxhathisa ukubola. I-geotextiles engalukwanga isetyenziswa ngokubanzi kwiiprojekthi ezininzi, ezinjengeendlela, iindlela zikaloliwe, ii-embankments, i-DAMS yamatye omhlaba, izikhululo zeenqwelo moya, amabala ezemidlalo, njl., Ukuqinisa iziseko ezibuthathaka, ngelixa udlala indima yokuzahlula kunye nokucoca. Ukongezelela, kukwafanelekile ukuqiniswa kwi-backfill yokugcina iindonga, okanye ukubethelela iipaneli zeendonga zokugcina, kunye nokwakhiwa kweendonga ezigciniweyo okanye i-abutments.
Uphawu
1. Amandla aphezulu: phantsi kobunzima obufanayo begram, ukomelela kwesilika ende ephothiweyo ngenaliti ye-nonwoven geotextiles kuwo onke amacala kuphezulu kunokwezinye ii-nonwovens ezidityanisiweyo, kwaye zinamandla aphezulu okuqina.
2. Ukusebenza kakuhle kwe-creep: Le geotextile inokusebenza kakuhle kwe-creep, inokugcina ukusebenza okuzinzileyo kusetyenziso lwexesha elide, kwaye akukho lula ukuyiguqula.
3. Ukuxhathisa okuqinileyo komhlwa, ukumelana nokwaluphala kunye nokumelana nobushushu: isilika ende ephothiweyo enenaliti engalukwanga ye-geotextile inokumelana nokugqwesa okugqwesileyo, ukumelana nokwaluphala kunye nokumelana nobushushu, kwaye inokusetyenziswa ixesha elide kwindawo erhabaxa ngaphandle komonakalo.
4. Ukusebenza okugqwesileyo kokugcinwa kwamanzi: ii-pores zayo zesakhiwo zinokulawulwa ngokufanelekileyo ukufezekisa ukufikeleleka okuthile, okufanelekileyo kwiiprojekthi ezifuna ukulawula ukuhamba kwamanzi.
5. Ukukhuselwa kwendalo kunye nokuqina, uqoqosho kunye nokusebenza kakuhle: xa kuthelekiswa nezinto zemveli, isilika ende ephothiweyo ebondwe i-geotextile ihambelana nokusingqongileyo, inokuphinda isetyenziswe kwaye isetyenziswe kwakhona, ukunciphisa umthwalo wokusingqongileyo, kunye nokuqina okuphezulu, ukuvezwa kwexesha elide kusenokugcina kuzinzile. ukusebenza, ukunciphisa kakhulu iindleko zokugcina.
6. Ulwakhiwo olulula: ulwakhiwo olufanelekileyo, aludingi itekhnoloji entsonkothileyo kunye nezixhobo, gcina abasebenzi kunye nezixhobo eziphathekayo, ezifanelekileyo kwiiprojekthi ngokukhawuleza.
Isicelo
Isetyenziswa kwindawo yohola wendlela, umzila kaloliwe, idama, unxweme oluselunxwemeni ukuze kunyanzeliswe ukunyanzeliswa, ukuhluzwa, ukwahlula kunye nokukhupha amanzi, ngakumbi asetyenziswa kwimigxobhozo yetyuwa nakwindawo yokungcwaba inkunkuma. Ikakhulu ekuhluzeni, ukuqiniswa kunye nokwahlula.
