Ukusetyenziswa kweGeogrid kwiDikes

Ukusukela ekuqaleni kweminyaka yoo-1980, i-China yaqala ukusetyenziswa kunye nophando lwezixhobo zokwenziwa ezifana ne-geotextiles.Ngokusetyenziswa kwayo kwiiprojekthi ezininzi, izibonelelo zesi sixhobo kunye netekhnoloji ziya ziqondwa ngakumbi luluntu lobunjineli.I-Geosynthetics inemisebenzi efana nokuhluzwa, ukukhutshwa kwamanzi, ukuhlukaniswa, ukuqinisa, ukuthintela ukukhupha, kunye nokukhusela.Phakathi kwabo, imisebenzi yokuqinisa (ingakumbi iintlobo ezintsha ze-geosynthetics) ziye zanda ukusetyenziswa kwiminyaka yamuva nje, kwaye iindawo zabo zokusetyenziswa ziye zanda ngokuthe ngcembe.Nangona kunjalo, ukusetyenziswa kobu buchwepheshe e-China akukabikho ngokubanzi, kwaye okwangoku kwinqanaba lokunyusa, ngakumbi kwiiprojekthi ezinkulu kunye neziphakathi.Inkqubo yomenzi weGeogrid

Kufunyaniswe ukuba ngoku, iigeogrid zisetyenziswa ikakhulu kuhola wendlela, kuloliwe, nakwezinye iiprojekthi, kodwa zikwasetyenziswa ngokuthe ngcembe kubunjineli behydraulic obufana nolawulo lwezandyondyo, i-cofferdams, kunye ne-inland port and wharf project.Ngokokusebenza kunye neempawu zegeogrids,

Eyona nto isetyenziswayo kwiprojekthi yile:

(1) Unyango olusisiseko.Ingasetyenziselwa ukuqinisa iziseko ezibuthathaka, ukuphucula ngokukhawuleza umthamo wokuthwala isiseko, kunye nokulawula ukuhlaliswa kwesiseko kunye nokuhlaliswa kokungalingani.Okwangoku, isetyenziswa kakhulu kuloliwe, uhola wendlela, kunye nezinye iiprojekthi ezineemfuno ezisezantsi kunyango lwesiseko.

(2) Ukuqiniswa kodonga olugcina umhlaba kunye nokubuyisela.Kwiindonga eziqinisiweyo zokugcina umhlaba, amandla e-tensile ye-geogrids kunye nezithintelo ekutshintsheni okusecaleni kwamasuntswana omhlaba kuya kwandisa kakhulu ukuzinza komhlaba ngokwawo.Okwangoku, isetyenziselwa ikakhulu ukuqinisa udonga lomzila kaloliwe kunye nethambeka lohola wendlela, ukubuyiswa kodonga lomlambo, kunye neeprojekthi ezithile zethambeka eliphezulu.

Kwiminyaka yakutshanje, ingqwalasela engakumbi ihlawulwe kulwakhiwo lolawulo lwezandyondyo kunye neeprojekthi zokukhusela iibhanki, kwaye inani leeprojekthi zokwakha liye landa, okukhokelela ekusetyenzisweni okubanzi kwee-geogrids kwiiprojekthi ze-embankment.Ngokukodwa kwiiprojekthi zodonga lwasezidolophini, ukuze kuncitshiswe indawo yomgangatho weprojekthi yodonga kunye nokwandisa izibonelelo zomhlaba ezixabisekileyo, ukukhuselwa kwethambeka lemilambo ihlala ithande ukwamkela ithambeka elinyukayo.Kwiiprojekthi ze-embankment ezizaliswe ngumhlaba kunye nelitye, xa izinto zokuzaliswa zingenako ukuhlangabezana neemfuno zokuzinza zokukhusela i-slope, ukusetyenziswa komhlaba oqiniweyo akukwazi ukuhlangabezana ngokufanelekileyo neemfuno zozinzo lokukhusela i-slope, kodwa kunokunciphisa ukuhlaliswa kokungalingani komzimba we-embankment body. , ngeenzuzo zobunjineli ezilungileyo.
