Imininingwane yokuhlangana kwamanethi okudonsa amanzi ahlanganisiwe anezinhlangothi ezintathu

Inethi yokukhipha amanzi ehlanganisiwe enezinhlangothi ezintathu iyinto yokukhipha amanzi evame ukusetshenziswa kumaphrojekthi amakhulu. Ngakho-ke, kufanele ihlanganiswe kanjani ngesikhathi sokwakha?

1. Ukulungiswa kwesiqondiso esihlangene

Uma ubeka inethi yokukhipha amanzi ehlanganisiwe enezinhlangothi ezintathu, lungisa indlela yokukhipha amanzi ukuze uqinisekise ukuthi ubude bendlela yokukhipha amanzi buqonde ngqo endleleni eyinhloko yomgwaqo noma iphrojekthi. Lokhu kulungiswa kuvumela inethi yokukhipha amanzi ukuthi igcine ukusebenza kahle kokukhipha amanzi lapho ithwala imithwalo, ithuthukise indlela yokugeleza kwamanzi, futhi ithuthukise ukusebenza kahle kokukhipha amanzi. Uma indlela yokukhipha amanzi ingalungiswanga kahle, kungaholela ekukhipheni amanzi kabi noma ekuqongeleleni kwamanzi endawo, okuthinta umphumela wephrojekthi.

2. Ukuphela kwezinto ezibonakalayo kanye nokuhlangana kwazo

Inethi yokudonsa amanzi ehlanganisiwe enezinhlangothi ezintathu kumele iqedwe, futhi ama-geotextile kuma-geonet cores aseduze kumele ahlanganiswe ngendlela yomugqa wezinto ezibonakalayo. Uma ugoqana, qiniseka ukuthi i-geotextile iyisicaba futhi ayinamibimbi, futhi ubude bokugoqana buhlangabezana nezidingo zomklamo. Ngokuvamile, ubude bokugoqana obude abungaphansi kuka-15cm, kanti ubude bokugoqana obuphambene bulawulwa ngaphakathi kobubanzi obungu-30-90cm. Ubude bokugoqana obunganele bungabangela amandla anganele ejoyintini, okuthinta ukuzinza kwenethi yokudonsa amanzi; kuyilapho ukugoqana ngokweqile kungandisa imfucuza yezinto zokwakha kanye nobunzima bokwakha.

3. Ukusetshenziswa kwezixhumi

Ekucutshungulweni kwamalunga, ukukhethwa nokusetshenziswa kwezixhumi kubaluleke kakhulu. Ngokuvamile, kusetshenziswa amabhakede epulasitiki amhlophe noma aphuzi noma amabhande e-polymer ukuxhuma ama-geonet cores emiqulwini ye-geotextile eseduze. Uma uxhuma, sebenzisa izixhumi ukuze uzilungise ngezikhathi ezithile (njenge-30cm noma i-1m) ngobude bomqulwini wezinto zokwakha. Izixhumi kumele zibe namandla anele nokuqina ukuqinisekisa ukuzinza kwamalunga. Uma izixhumi zisetshenziswa ngendlela engafanele, amalunga angase akhululeke noma awe, okuthinta umphumela wokukhipha amanzi wenethi yokukhipha amanzi.

4. Ukulungiswa kwama-geotextile ahambisanayo

Uma inethi yokudonsa amanzi ehlanganisiwe enezinhlangothi ezintathu ibekwa phakathi kwesisekelo, isisekelo kanye nesisekelo esingaphansi, ama-geotextile ahambisanayo kumele alungiswe. Izindlela zokulungisa zifaka phakathi ukushibiliza okuqhubekayo, ukushibiliza ikhanda eliyisicaba noma ukuthunga. Uma ushibiliza, qiniseka ukuthi ama-weld ahlanzekile, amahle futhi awashibiliki futhi awashibiliki; uma uthunga, ukushibiliza ikhanda eliyisicaba noma ukuthunga okuvamile kungasetshenziswa ukuhlangabezana nezidingo zobude obuncane bokuthunga. Ukulungisa kungathuthukisa amandla nokuzinza kwamajoyinti futhi kuvimbele ama-geotextile ukuthi angasuswa noma alimale ngesikhathi sokufakwa kwama-filler.

5. Ukwelashwa kwendawo ekhethekile

Ezindaweni ezikhethekile, njengalapho kukhona amatshe aqinile ebusweni bomcamelo wesisekelo samatshe, ukuze kuvinjelwe ukuthi angabhobozi i-geomembrane engangeni amanzi, ungqimba oluncane lwesihlabathi esixubile (ubukhulu obungu-3-5cm) kufanele lusakazwe bese lugoqwa ebusweni bomcamelo wesisekelo samatshe. Ungqimba lwesihlabathi kufanele lumboze ngokuphelele ubuso bomcamelo wesisekelo samatshe, futhi akufanele kube khona umcamelo onobukhulu bezinhlayiya obungaphezu kuka-4mm ongqimbeni lwesihlabathi. Lapho kwakhiwa ezindaweni ezibandayo noma ezishisayo kakhulu, kufanele kuthathwe izinyathelo zokuzivikela ezifanele, njengezixhumi zokushisa nokulungisa isikhathi sokwakha, ukuqinisekisa ukuthi ikhwalithi yamalunga ayithinteki yimvelo.

Njengoba kungabonakala ngenhla, ukwelashwa okuhlangene kwenethi yokukhipha amanzi ehlanganisiwe enezinhlangothi ezintathu kuyisixhumanisi esibalulekile enkambisweni yokwakha, okuhlobene ngqo nomphumela wokukhipha amanzi kanye nokuqina okuphelele kwenethi yokukhipha amanzi. Ukulandela imininingwane yokulungiswa kwesiqondiso sejoyinti, ukuphela kwezinto kanye nokugqagqana, ukusetshenziswa kwesixhumi, ukulungiswa kwe-geotextile egqagqana kanye nokwelashwa kwendawo ekhethekile kungaqinisekisa amandla nokuzinza kwamalunga futhi kuthuthukise ukusebenza kahle kokukhipha amanzi kanye nokuphila kwenkonzo yenethi yokukhipha amanzi.
