I-geotextile emhlophe engu-100% engalukiwe yokwakhiwa kwedamu lomgwaqo
Incazelo emfushane:
I-geotextiles engalukiwe inezinzuzo eziningi, njengokungena komoya, ukuhlunga, ukwahlukanisa, ukumuncwa kwamanzi, ukungangeni kwamanzi, ukuhoxiswa, ukuzizwa kumnandi, ukuthambile, ukukhanya, ukunwebeka, ukubuyiseleka, akukho ukuqondiswa kwendwangu, ukukhiqiza okuphezulu, isivinini sokukhiqiza kanye namanani aphansi. Ngaphezu kwalokho, iphinde ibe namandla aphezulu okudonsa kanye nokumelana nezinyembezi, ukugeleza okuhle kokuma okuqondile nokuvundlile, ukuhlukaniswa, ukuzinza, ukuqinisa kanye neminye imisebenzi, kanye nokungena kahle nokusebenza kokuhlunga.
Incazelo Yemikhiqizo
Ama-geotextile angalukwanga ayizinto ze-geosynthetic ezikwazi ukungena emanzini ezenziwe ngemicu yokwenziwa ngokuyinaliti noma ngokulukwa. Inokuhlunga okuhle kakhulu, ukuhlukaniswa, ukuqiniswa nokuvikela, kuyilapho amandla aqinile aphezulu, ukungena kahle, ukumelana nokushisa okuphezulu, ukumelana nokuqandisa, ukumelana nokuguga, ukumelana nokugqwala. I-geotextiles engalukiwe isetshenziswa kabanzi kumaphrojekthi amaningi, njengemigwaqo, izitimela, ama-embankments, i-Earth-rock DAMS, izikhumulo zezindiza, izinkundla zemidlalo, njll., ukuqinisa izisekelo ezibuthakathaka, ngenkathi idlala indima yokuhlukaniswa nokuhlunga. Ngaphezu kwalokho, ibuye ifanele ukuqiniswa ekufakweni kwe-backfill yokugcina izindonga, noma ukuhlanganisa amaphaneli okugcina izindonga, kanye nokwakha izindonga ezigoqekile ezigcinayo noma ama-abutments.
Isici
1. Amandla aphezulu: ngaphansi kokucaciswa kwesisindo esifanayo segremu, amandla aqinile kasilika omude ophothelwe ngenaliti ye-nonwoven geotextiles kuzo zonke izinhlangothi aphakeme kunawamanye ama-nonwovens anenaliti, futhi anamandla aqinile aqinile.
2.Ukusebenza kahle kwe-creep: Le geotextile inokusebenza kahle kwe-creep, ingakwazi ukugcina ukusebenza okuzinzile lapho isetshenziswa isikhathi eside, futhi akulula ukuyishintsha.
3. Ukumelana nokugqwala okuqinile, ukumelana nokuguga kanye nokumelana nokushisa: i-geotextile ende kasilika ephothiwe enenaliti enenaliti inokumelana nokugqwala okuhle kakhulu, ukumelana nokuguga nokumelana nokushisa, futhi ingasetshenziswa isikhathi eside endaweni enokhahlo ngaphandle kokulimala.
4. Ukusebenza kahle kakhulu ukongiwa kwamanzi: izimbotshana zawo zesakhiwo zingalawuleka ngempumelelo ukuze kufinyelele izinga elithile lokungena, elifanele amaphrojekthi adinga ukulawula ukugeleza kwamanzi.
5. Ukuvikelwa kwemvelo futhi kuhlala isikhathi eside, ukonga kanye nokusebenza kahle: uma kuqhathaniswa nezinto zendabuko, i-geotextile ende ephothiwe nge-bonded ivumelana nemvelo, ingagaywa kabusha futhi isetshenziswe kabusha, yehlise umthwalo wemvelo, nokuqina okuphezulu, ukuchayeka isikhathi eside kusengagcina kuzinzile. ukusebenza, kunciphisa kakhulu izindleko zokunakekela.
6. Ukwakhiwa okulula: ukwakhiwa okulula, akudingi ubuchwepheshe obuyinkimbinkimbi nemishini, londoloza abasebenzi kanye nezinsiza ezibonakalayo, ezifanele amaphrojekthi ngokushesha.
Isicelo
Isetshenziswa endaweni yomgwaqo onguthelawayeka, ujantshi wesitimela, idamu, ogwini lolwandle ukuze kuqiniswe amandla, ukuhlunga, ukuhlukanisa kanye nokukhipha amanzi, ikakhulukazi esetshenziswa ezindaweni ezinosawoti kanye nenkundla yokungcwaba udoti. Ikakhulukazi ekuhlungeni, ekuqiniseni nasekuhlukaniseni.
