Isisekelo somhlabathi othambile sinezici zokuqukethwe kwamanzi amaningi, amandla okuthwala aphansi kanye nokuguquguquka okulula, okuthinta kakhulu ukuzinza kwesisekelo. Inethi yokudonsa amanzi ehlanganisiwe enama-dimensional amathathu iyinto yokudonsa amanzi evame ukusetshenziswa kwezobunjiniyela. Ngakho-ke ingasetshenziswa yini esisekelweni somhlabathi othambile?
1. Izici zesakhiwo senethi yokudonsa amanzi ehlanganisiwe enezinhlangothi ezintathu
Inethi yokudonsa amanzi ehlanganisiwe enezinhlangothi ezintathu uhlobo olusha lwezinto zokudonsa amanzi ezenziwe nge-polyethylene ephezulu (i-HDPE) njengezinto zokusetshenziswa futhi zicutshungulwa ngenqubo ekhethekile yokubumba i-extrusion. Inesakhiwo esikhethekile esinezingqimba ezintathu: izimbambo eziphakathi ziqinile futhi zihlelwe ngobude ukuze zenze isiteshi sokudonsa amanzi; izimbambo ezihlelwe ngokunqamula phezulu naphansi zakha ukwesekwa ukuvimbela ngempumelelo i-geotextile ukuthi ingangeni emgudwini wokudonsa amanzi. Lesi sakhiwo senza inethi yokudonsa amanzi ehlanganisiwe enezinhlangothi ezintathu ukuthi igcine ukusebenza okuphezulu kokudonsa amanzi ngisho nangaphansi kwemithwalo ephezulu. Ngaphezu kwalokho, i-geotextile eboshwe zinhlangothi zombili ithuthukisa ukusebenza kwayo okuphelele kokulwa nokuhlunga, ukudonsa amanzi, ukuphefumula kanye nokuvikela.
2. Indlela yokusebenza kwenetha yokudonsa amanzi ehlanganisiwe enezinhlangothi ezintathu ekwelashweni kwesisekelo senhlabathi ethambile
1. Umphumela wokukhipha amanzi kanye nokuhlanganiswa: ukubeka inethi yokukhipha amanzi ehlanganisiwe enezinhlangothi ezintathu esisekelweni senhlabathi ethambile kungakha umzila wokukhipha amanzi ophumelelayo ukuze kukhishwe amanzi aqongelelwe esisekelweni ngokushesha. Kunganciphisa okuqukethwe kwamanzi esisekelweni, kusheshiswe inqubo yokuhlanganisa inhlabathi, futhi kuthuthukiswe amandla okuthwala kanye nokuqina kwesisekelo.
2. Ukuvimba ukukhuphuka kwamanzi e-capillary: Ngokuvamile kunenkinga yokukhuphuka kwamanzi e-capillary ezindaweni ezithambile zomhlabathi, okuzokwenza ukuthi umswakama wesisekelo wande futhi kuthinte amandla nokuqina kwesisekelo. Inethi yokudonsa amanzi ehlanganisiwe enama-three-dimensional ingavimba ukukhuphuka kwamanzi e-capillary, igcine isisekelo somile, futhi ithuthukise amandla okuthwala esisekelo.
3. Thuthukisa ukuzinza kwesisekelo: Inethi yokukhipha amanzi ehlanganisiwe enezinhlangothi ezintathu ayigcini nje ngokuba nomsebenzi wokukhipha amanzi, kodwa futhi ingakha isakhiwo esihlanganisiwe nenhlabathi. Ngokusebenzisana kwenhlabathi negridi, amandla okusika kanye nekhono lokuthwala inhlabathi kuyakhula. Lo mphumela wokuqinisa ukuhlanganiswa ungathuthukisa ukuzinza kanye nokuphepha kwesisekelo.
III. Ukusetshenziswa kwamanethi okudonsa amanzi ahlanganisiwe anezinhlangothi ezintathu ekuphathweni kwesisekelo senhlabathi ethambile
Amanetha okukhipha amanzi ahlanganisiwe anama-three-dimensional angasetshenziswa ekulungisweni kwemigwaqo kanye nasezinhlelweni zokukhipha amanzi. Lapho umgwaqo uguga futhi uqhekeka, iningi lamanzi emvula lizongena engxenyeni. Ngalesi sikhathi, ukubeka inetha lokukhipha amanzi elihlanganisiwe elinama-three-dimensional ngqo ngaphansi kobuso bomgwaqo kungathatha indawo yesisekelo esikhishwa amanzi, kuqoqwe futhi kukhishwe amanzi, futhi kuvimbele amanzi ukuthi angangeni esisekelweni/esingaphansi komhlaba. Ekwakhiweni kwengqalasizinda yezokuthutha njengesitimela nemigudu, amanetha okukhipha amanzi ahlanganisiwe anama-three-dimensional avame ukusetshenziswa ekuphathweni kombhede womgwaqo kanye nasekuphathweni kokukhipha amanzi odongeni lwangaphakathi lwemigudu, okungaxazulula inkinga yokuqongelela kwamanzi esisekelweni futhi kuthuthukise ukuzinza kanye namandla okuthwala isakhiwo.
Njengoba kungabonakala kulokhu okungenhla, inethi yokukhipha amanzi ehlanganisiwe enezinhlangothi ezintathu ingasetshenziswa ekwelapheni isisekelo senhlabathi ethambile. Ingaxazulula inkinga yokukhipha amanzi ezisekelweni zenhlabathi ethambile futhi ithuthukise amandla okuthwala kanye nokuqina kwesisekelo.
