Inethiwekhi yokudonsa amanzi ehlanganisiwe yakhiwe yizingxenye eziningana

Ekwakhiweni kobunjiniyela bezokwakha kanye nengqalasizinda yesimanje, uhlelo lokukhipha amanzi lubaluleke kakhulu. Inethiwekhi yokukhipha amanzi ehlanganisiwe inokusebenza kahle kakhulu kokukhipha amanzi, amandla aphezulu kanye nokuqina, futhi ivame ukusetshenziswa emigwaqweni, ezitimeleni, emihubheni, kumaphrojekthi okulondolozwa kwamanzi kanye nasezindaweni zokulahla udoti. Ngakho-ke, zingaki izingxenye ezenziwe ngayo?

Inethi yokukhipha amanzi ehlanganisiwe yakhiwe yizingxenye ezintathu eziyinhloko: umgogodla we-mesh wepulasitiki, i-geotextile engena emanzini kanye nesendlalelo sokunamathela esihlanganisa lokhu okubili. Lezi zingxenye ezintathu zisebenza ndawonye ukuqinisekisa ukukhishwa kwamanzi okusebenzayo, amandla aphezulu kanye nokuqina kwenethiwekhi yokukhipha amanzi ehlanganisiwe.

1, i-Plastic mesh core

（1）I-plastic mesh core iyisisekeli esiyinhloko sesakhiwo senethi yokudonsa amanzi ehlanganisiwe, eyenziwe nge-polyethylene enobukhulu obuphezulu (HDPE) Izinto zepulasitiki ezilinganayo ezinamandla aphezulu zenziwa ngenqubo ekhethekile yokubumba i-extrusion. Inesakhiwo esiyingqayizivele esinezinhlangothi ezintathu, esakhiwa yizimbambo eziqondile nezivundlile ezihlela ngokuhlanganisa. Lezi zimbambo azigcini nje ngokuba nokuqina okuphezulu futhi zingakha isiteshi sokudonsa amanzi esisebenzayo, kodwa futhi ziyasekelana ukuvimbela i-geotextile ukuthi ingangeniswa emgudwini wokudonsa amanzi, ukuqinisekisa ukuzinza nokusebenza kokudonsa amanzi kwenethi yokudonsa amanzi ngaphansi komthwalo omkhulu.

（2）Kunemiklamo ehlukahlukene ye-plastic mesh core, kufaka phakathi i-two-dimensional mesh core kanye ne-three-dimensional mesh core. I-two-dimensional mesh core yakhiwe i-drainage mesh core enesakhiwo se-two-ribs, kuyilapho i-three-dimensional mesh core iqukethe i-three-dimensional mesh ribs, ezakha isakhiwo esiyinkimbinkimbi kakhulu esikhaleni, enikeza amandla aphezulu okukhipha amanzi kanye namandla okucindezela. Ikakhulukazi inethiwekhi yokukhipha amanzi ehlanganisiwe ene-three-dimensional, isakhiwo sayo esiyingqayizivele singakhipha ngokushesha amanzi angaphansi komgwaqo futhi sivimbe amanzi e-capillary ngaphansi komthwalo omkhulu, okudlala indima ekuhlukaniseni nasekuqiniseni isisekelo.

2, i-geotextile engenela emanzini

（1）I-geotextile engenela emanzini ingenye ingxenye ebalulekile yenethi yokudonsa amanzi ehlanganisiwe, evame ukuhlanganiswa eduze nezinhlangothi zombili noma ohlangothini olulodwa lwe-plastic mesh core ngenqubo yokubopha ngokushisa. I-geotextile engenela emanzini yenziwe nge-geotextile engalukiwe ebhobozwe ngenaliti, enekhono elihle kakhulu lokungena kwamanzi kanye nokusebenza kokulwa nokuhlunga. Amandla ayo okuvimbela izinhlayiya zomhlabathi kanye nokungcola okuncane ukuthi kungangeni emgudwini wokudonsa amanzi, futhi ivumela umswakama ukuthi udlule ngokukhululeka, iqinisekisa uhlelo lokudonsa amanzi olungavimbelwe.

（2）Ukukhethwa kwe-geotextile engenela emanzini kunethonya elibalulekile ekusebenzeni kwenethi yokudonsa amanzi ehlanganisiwe. I-geotextile engenela emanzini esezingeni eliphezulu ayigcini nje ngokuba nosayizi omuhle wembobo ebonakalayo, ukungena kwamanzi kanye nokungena kwamanzi, kodwa futhi inamandla aphezulu okubhoboza, amandla okudabuka kwe-trapezoidal kanye namandla okubamba okubamba, ukuze kuqinisekiswe ukuthi ingamelana namandla ahlukahlukene angaphandle kanye nokuguguleka kwemvelo ekusetshenzisweni kwesikhathi eside.

3, ungqimba olunamathelayo

（1）Isendlalelo sokunamathela siyingxenye ebalulekile yokuxhumanisa umongo we-mesh yepulasitiki kanye ne-geotextile engenela emanzini. Senziwe ngezinto ezikhethekile ze-thermoplastic. Ngenqubo yokubopha eshisayo, ungqimba lokunamathela lungahlanganisa ngokuqinile umongo we-mesh yepulasitiki kanye ne-geotextile engenela amanzi ukuze kwakheke inethi yokudonsa amanzi ehlanganisiwe enesakhiwo esihlanganisiwe. Lesi sakhiwo asigcini nje ngokuqinisekisa ukuzinza nokuqina kwenethi yokudonsa amanzi, kodwa futhi senza ukufakwa nokubekwa kwayo kube lula futhi kusheshe.

（2） Ukusebenza kwesendlalelo sokunamathela kunethonya elibalulekile ekusebenzeni kahle kokukhipha amanzi kanye nekhono lokulwa nokuguga kwenethi yokukhipha amanzi ehlanganisiwe. Isendlalelo sokunamathela esisezingeni eliphezulu singaqinisekisa ukuthi inethi yokukhipha amanzi ngeke ihlukane noma iwe ngesikhathi sokusetshenziswa isikhathi eside, futhi singaqinisekisa ukuqhubeka nokuzinza kohlelo lokukhipha amanzi.

Njengoba kungabonakala ngenhla, inethi yokudonsa amanzi ehlanganisiwe yakhiwe yizingxenye ezintathu: umongo we-mesh yepulasitiki, i-geotextile engenela emanzini kanye nengqimba yokunamathela. Lezi zingxenye zisebenza ndawonye ukuqinisekisa ukuthi i-drainage iyasebenza kahle, amandla aphezulu kanye nokuqina kwenethi yokudonsa amanzi ehlanganisiwe.
