Kusukela ekuqaleni kwawo-1980, i-China yaqala ukusetshenziswa nokucwaninga kwezinto zokwenziwa ezifana ne-geotextiles.Ngokusetshenziswa kwayo kumaphrojekthi amaningi, izinzuzo zale nto kanye nobuchwepheshe ziya ngokuya ziqashelwa umphakathi wobunjiniyela.I-Geosynthetics inemisebenzi efana nokuhlunga, ukukhipha amanzi, ukuhlukaniswa, ukuqinisa, ukuvimbela ukugeleza kwamanzi, nokuvikela.Phakathi kwazo, imisebenzi yokuqinisa (ikakhulukazi izinhlobo ezintsha ze-geosynthetics) iye yasetshenziswa kakhulu eminyakeni yamuva nje, futhi izinkambu zabo zokufaka isicelo ziye zanda kancane kancane.Kodwa-ke, ukusetshenziswa kwalobu buchwepheshe e-China akukakasakazeki, futhi okwamanje kusesiteji sokuphromotha, ikakhulukazi kumaphrojekthi amakhulu naphakathi.Isistimu yomkhiqizi we-Geogrid
Kutholwe ukuthi njengamanje, ama-geogrid asetshenziswa kakhulu emigwaqweni emikhulu, kuloliwe, nakwamanye amaphrojekthi, kodwa futhi kancane kancane asetshenziswa kubunjiniyela bamanzi asetshenziswayo njengamanzingo okulawula izikhukhula, amadamu ama-cofferdam, kanye namaphrojekthi aphakathi nezwe kanye namachweba.Ngokusho kokusebenza nezici ze-geogrids,
Ukusetshenziswa kwayo okuyinhloko kuphrojekthi yilezi:
(1) Ukwelashwa kwesisekelo.Ingasetshenziselwa ukuqinisa izisekelo ezibuthakathaka, ukuthuthukisa ngokushesha umthamo wokuthwala isisekelo, nokulawula ukuxazululwa kwesisekelo kanye nokuxazululwa ngokungalingani.Njengamanje, isetshenziswa kakhulu kuloliwe, umgwaqo omkhulu, nakwamanye amaphrojekthi anezidingo eziphansi zokwelashwa kwesisekelo.
(2) Udonga oluqinisiwe olugcina inhlabathi kanye nokubuyisela.Ezindongeni eziqinisiwe zokugcina umhlaba, amandla aqinile we-geogrid kanye nezingqinamba ekugudluzweni kwezinhlayiya zenhlabathi kuzokwandisa kakhulu ukuzinza kwenhlabathi ngokwayo.Njengamanje, isetshenziswa kakhulu ukuqinisa izindonga zemithambeka kaloliwe kanye nothelawayeka, ukubuyiswa konqenqema lomfula, kanye namaphrojekthi athile emithambeka aphezulu.
Eminyakeni yamuva nje, kuye kwaqashelwa kakhulu ekwakhiweni kokulawulwa kwezikhukhula kanye namaphrojekthi okuvikela amabhange, futhi inani lamaphrojekthi wokwakha liye landa, okuholela ekusetshenzisweni okubanzi kwama-geogrid kumaphrojekthi wokuhlanganisa.Ikakhulukazi kumaphrojekthi othango lwasemadolobheni, ukuze kuncishiswe indawo ephansi yephrojekthi yothango futhi kwandiswe izinsiza zomhlaba ezibalulekile, ukuvikelwa komthambeka wezingongolo zemifula kuhlale kuthambekele ekuthatheni umqansa.Kumaphrojekthi we-embankment agcwele umhlaba kanye namadwala, lapho izinto zokugcwalisa zingakwazi ukuhlangabezana nezidingo zokuzinza zokuvikela umthambeko, ukusetshenziswa komhlabathi oqinisiwe akukwazi nje ukuhlangabezana ngokuphumelelayo nezidingo zokuzinza zokuvikela umthambeka, kodwa futhi kunganciphisa ukuxazululwa kokungalingani komzimba we-embankment. , ngezinzuzo ezinhle zobunjiniyela.
