Inethiwekhi yokudonsa amanzi ehlanganisiwe inokusebenza kahle kakhulu kokudonsa amanzi, amandla aphezulu okudonseka kanye nokuqina okuhle. Iyinto evame ukusetshenziswa kwezobunjiniyela bemigwaqo emikhulu. Ngakho-ke, yiziphi izinhlelo zayo ezikhethekile kwezobunjiniyela bemigwaqo emikhulu?
1. Izici eziyisisekelo zenethiwekhi yokudonsa amanzi ehlanganisiwe
Inethi yokudonsa amanzi ehlanganisiwe yenziwe nge-polyethylene enobukhulu obuphezulu (i-HDPE） Isakhiwo senethiwekhi esinezinhlangothi ezintathu esenziwe ngezinto ezinjalo ze-polymer, futhi ubuso ngokuvamile buhlanganiswa ne-geotextile engalukiwe. Inezici ezilandelayo eziyisisekelo:
1、Ukusebenza kahle kakhulu kokukhipha amanzi: Isakhiwo senethiwekhi esinezinhlangothi ezintathu senethiwekhi yokukhipha amanzi ehlanganisiwe sinikeza umzila wokukhipha amanzi obushelelezi, ongakhipha amanzi amaningi ngokushesha enhlabathini futhi ugcine umgwaqo womile futhi uzinzile.
2、Amandla aphezulu okudonswa: Izinto ngokwazo zinamandla aphezulu okudonswa futhi zingamelana nokucindezeleka okubangelwa ukuguquguquka kwe-subgrade kanye nomthwalo wemoto, okungaqinisekisa ukuzinza kwesikhathi eside kohlelo lokukhipha amanzi.
3、Ukuqina Okuhle: Inethiwekhi yokukhipha amanzi ehlanganisiwe inezici zokumelana nokugqwala, ukumelana ne-asidi ne-alkali, kanye nokulwa nokuguga. Ingasetshenziswa isikhathi eside ngaphansi kwezimo zemvelo ezinzima futhi yandise impilo yenkonzo yomgwaqo.
2. Izimo zokusetshenziswa kwenethiwekhi yokudonsa amanzi ehlanganisiwe kubunjiniyela bomgwaqo omkhulu
1, amanzi angaphansi komhlaba
Ekwakhiweni kwe-subgrade yomgwaqo omkhulu, inethiwekhi yokudonsa amanzi ehlanganisiwe ivame ukufakwa phansi noma emthambekeni we-subgrade, engakhipha amanzi angaphansi komhlaba kanye namanzi emvula, futhi ivimbele i-road gene ukuthi ithambise futhi ihlale ngenxa yokuqongelela kwamanzi.
2, Ukuvikelwa kwe-Slope
Emthambekeni omkhulu, inethiwekhi yokudonsa amanzi ehlanganisiwe ayikwazi nje ukukhipha amanzi, kodwa futhi iqinise umthambekeni futhi ivimbele ukuguguleka kwenhlabathi. Uma ihlanganiswe nezitshalo, ingakha ukuvikelwa komthambekeni wemvelo futhi ithuthukise ukuzinza kanye nobuhle bomthambekeni.
3, Ukugeleza kwamanzi kwesendlalelo sesakhiwo sendlela
Engqimbeni yesakhiwo sendlela, inethiwekhi yokudonsa amanzi ehlanganisiwe ingafakwa phakathi kwengqimba yesisekelo kanye nengqimba yesisekelo esingaphansi, engakhipha amanzi aqongelelekile phakathi kwengqimba futhi ivimbele izifo zendlela ezibangelwa amanzi aqongelelekile, njengemifantu, imigodi, njll. Ukushelela kobuso bomgwaqo kanye nenduduzo yokuhamba kungathuthukiswa.
3. Izinzuzo zenethiwekhi yokudonsa amanzi ehlanganisiwe kubunjiniyela bemigwaqo emikhulu
1、Thuthukisa ukuzinza komgwaqo: Ngokusebenzisa amanzi ahlanzekile ngempumelelo, inethiwekhi yokudonsa amanzi ehlanganisiwe inganciphisa ukuvela kwezifo ezibangelwa yimigwaqo kanye nezingozi zomgwaqo futhi ithuthukise ukuzinza komgwaqo jikelele.
2、Nweba impilo yesevisi: Ukuqina kanye nezakhiwo zokulwa nokuguga kwenethi yokudonsa amanzi ehlanganisiwe kuyivumela ukuthi igcine umphumela wokudonsa amanzi ozinzile isikhathi eside, okungandisa impilo yesevisi yomgwaqo.
3、Ukwakhiwa okulula: Inethiwekhi yokudonsa amanzi ehlanganisiwe ithambile ngobunjalo bayo, kulula ukuyibeka nokuyisika, futhi isebenza kahle kakhulu ekwakheni, okunganciphisa isikhathi sokwakha futhi kunciphise izindleko.
4、Ukuvikelwa kwemvelo nokonga amandla: Ukukhiqizwa nokusetshenziswa kwamanethiwekhi okudonsa amanzi ahlanganisiwe akunawo umthelela omkhulu emvelweni futhi kuhlangabezana nezidingo zokuvikelwa kwemvelo zokwakha ubunjiniyela besimanje.
