Inethiwekhi yokudonsa amanzi ye-geotechnical ehlanganisiwe Yenziwe nge-geotextile ekhethekile ye-geonet enezinhlangothi ezimbili eboshiwe. Ihlanganisa i-geotextile (isenzo sokulwa nokuhlunga) kanye ne-geonet (isenzo sokudonsa amanzi nokuvikela) ukuze inikeze umphumela ophelele "wokuvikela amanzi okudonsa amanzi okuvimbela ukuhlunga". Inethiwekhi yokudonsa amanzi ehlanganisiwe enezinhlangothi ezintathu Iyinto entsha yokwenziwa kwe-geo. Isakhiwo esiyinhloko siwumgogodla we-geonet onezinhlangothi ezintathu one-geotextile engalukiwe eboshwe ngenaliti enamathiselwe nhlangothi zombili. Umgogodla we-geonet onezinhlangothi ezintathu uhlanganisa ubambo olulodwa olujiyile oluqondile, kanye nobambo olulodwa oluthambekele phezulu naphansi. Ingakhipha amanzi angaphansi komhlaba ngokushesha emgwaqweni, futhi inesistimu yokulungisa imigodi, engavimba amanzi e-capillary ngaphansi komthwalo omkhulu.
Ngemva kokuguga komgwaqo kanye nokuqhekeka, iningi lamanzi emvula lizongena esigabeni. Kulesi simo, inethiwekhi yokudonsa amanzi e-Composite enezinhlangothi ezintathu Ibekwe ngqo ngaphansi kwendlela esikhundleni sesisekelo esingakhishwa amanzi. Inethiwekhi yokudonsa amanzi e-composite enezinhlangothi ezintathu ingasetshenziswa lapho amanzi engena esisekelweni /Isendlalelo esingaphansi kwesisekelo siqoqwa kuqala. Kodwa futhi ifilimu ingasongwa ekugcineni kwenethi yokudonsa amanzi e-composite enezinhlangothi ezintathu ukuze kuvinjelwe umswakama ukuthi ungangeni esisekelweni. Ezinhlelweni zomgwaqo eziqinile, lokhu kulungiselelwa kuvumela ama-coefficient aphezulu okudonsa amanzi e-Cd Ukuklama umgwaqo. Enye inzuzo yalesi sakhiwo ukuthi singavumela ukhonkolo ukuthi umanziswe ngokulinganayo (ucwaningo mayelana nobubanzi balesi nzuzo luyaqhubeka). Kungakhathaliseki ukuthi imigwaqo eqinile noma izinhlelo zomgwaqo eziguquguqukayo, lesi sakhiwo singandisa impilo yenkonzo yemigwaqo.
Inethi yokudonsa amanzi ye-geotechnical ehlanganisiwe iqukethe i-geotextile eyisicaba ebhobozwe ngenaliti ezinhlangothini zombili kanye ne-composite three-dimensional mesh core phakathi. Ngokuvala ukushisa komshini, i-geotextile kanye ne-three-dimensional mesh core zivalwe ngokushisa ndawonye ukuze zakhe inethiwekhi yokudonsa amanzi ene-dimensional ezintathu enesakhiwo sokudonsa amanzi esine-dimensional ezintathu. Ingadlala indima yokuhlunga nokukhuculula amanzi. Inethi yokudonsa amanzi ene-dimensional ezintathu iqukethe ungqimba lwe-composite geomembrane kanye nengqimba ye-geotextile kanye nengqimba ye-three-dimensional mesh core ehlanganiswe phakathi; Ngokuvala ukushisa komshini, i-geotextile composite geomembrane kanye ne-three-dimensional mesh core zivalwe ngokushisa ndawonye ukuze zakhe inethiwekhi yokudonsa amanzi ene-dimensional ezintathu kanye nesakhiwo sokudonsa amanzi, esetshenziswa kakhulu ekukhipheni amanzi, kanti i-composite geomembrane idlala indima engangeni manzi.
Inethi yokukhipha amanzi ehlanganisiwe enezinhlangothi ezintathu iyinto entsha yokwenziwa kwe-geo. Isakhiwo esiyinhloko siwumgogodla we-geonet onezinhlangothi ezintathu one-geotextile engalukiwe enembobo eboshwe ngenaliti enamathiselwe nhlangothi zombili. I-geonet core enezinhlangothi ezintathu ifaka ubambo olulodwa olujiyile oluqondile, kanye nobambo olulodwa oluthambekele phezulu naphansi. Ingakhipha amanzi angaphansi komhlaba ngokushesha emgwaqweni, futhi inesistimu yokulungisa imbobo, engavimba amanzi e-capillary ngaphansi komthwalo omkhulu. Ngesikhathi esifanayo, ingadlala indima yokuhlukaniswa kanye nokuqinisa isisekelo. Izinto ezintsha zokwenziwa kwe-geosynthetic. Inethi yokukhipha amanzi ehlanganisiwe enezinhlangothi ezintathu yenziwe nge-geotextile ekhethekile enezinhlangothi ezintathu enezinhlangothi ezimbili. Ihlanganisa i-geotextile (isenzo sokulwa nokuhlunga) kanye ne-geonet (isenzo sokukhipha amanzi kanye nokuvikela) ukuze inikeze umphumela ophelele "wokuvikela amanzi okukhipha amanzi". Isakhiwo esiyingqayizivele sezinhlangothi ezintathu se-composite drainage core enezinhlangothi ezintathu singamelana nemithwalo ephezulu yokucindezela phakathi nenqubo yonke yokusebenzisa, futhi singagcina ukujiya okukhulu, sinikeze ukuhamba kahle kwamanzi.
