一. Ukulungiselela ukwakhiwa
1. Ukwelashwa ngezinga lotshani
Ngaphambi kokubeka inethiwekhi yokukhipha amanzi ye-geocomposite, ungqimba lwesisekelo kufanele luhlanzwe kahle ukuqinisekisa ukuthi azikho izimbobo eziqinile ezifana namatshe ayigugu namabhulokhi ebusweni, futhi ukuthamba kanye nokuminyana okudingekayo ngomklamo kufanele kuhlangatshezwane nakho. Ukuthamba akufanele kube ngaphezu kuka-15 mm, Izinga lokuminyana kufanele lihlangabezane nezindinganiso zokuklama zobunjiniyela. Ubuso bengqimba lesisekelo kufanele futhi bugcinwe bomile ukuze kugwenywe ithonya lomswakama ekusebenzeni kwenetha yokukhipha amanzi.
2, ukuhlolwa kwezinto
Ngaphambi kokwakha, inethiwekhi yokudonsa amanzi ye-geocomposite kufanele ihlolwe ngokuphelele ukuqinisekisa ukuthi ayonakali noma ayonakalisiwe, futhi ihlangabezana nezidingo zomklamo. Kufanele kuqashelwe ngokukhethekile ukuhlola ingxenye eyinhloko yenethi yokudonsa amanzi ukuqinisekisa ukuthi isakhiwo sayo esinezinhlangothi ezintathu siphelele futhi asinazo iziphazamiso noma umonakalo.
3. Izimo Zemvelo
Uma kufakwa inethiwekhi yokudonsa amanzi ye-geocomposite, izinga lokushisa langaphandle kufanele libe ngu-5 ℃. Lingenziwa ngaphansi kwezimo zezulu ezingaphezulu, amandla omoya angaphansi kwezinga lesi-4, futhi kungabikho mvula noma iqhwa, ukuze kuqinisekiswe ikhwalithi yokwakha.
二. Imininingwane yokubeka
1, isiqondiso sokubeka
Amanethiwekhi okudonsa amanzi ahlanganisiwe kumele abekwe phansi emthambekeni, kuqinisekiswe ukuthi ubude buhambisana nokugeleza kwamanzi. Kweminye imithambeka emide nephakeme, kufanele kunakwe ngokukhethekile ukusebenzisa ubude obuphelele bokugoqa izinto phezulu emthambekeni ukuze kugwenywe ukuthinta umphumela wokudonsa amanzi ngenxa yokusikwa.
2, Ukuphathwa kwezithiyo
Uma uhlangabezana nezithiyo ngesikhathi sokubekwa, njengamapayipi okukhipha amanzi noma imithombo yokuqapha, sika inethi yokukhipha amanzi bese ulala eduze kwezithiyo ukuqinisekisa ukuthi akukho sikhala phakathi kwezithiyo nezinto zokwakha. Uma usika, i-geotextile engezansi kanye ne-geonet core yenethi yokukhipha amanzi ehlanganisiwe kufanele ihlangane nezithiyo, kanti i-geotextile engenhla kufanele ibe nomkhawulo owanele, ukuze ikwazi ukugoqwa ngaphansi kwenethi yokukhipha amanzi ukuze kuvikelwe i-geonet core eveziwe.
3, Izidingo zokubeka
Uma ubeka, inethi yokukhipha amanzi kufanele iqondiswe futhi ibushelelezi, eduze kwesendlalelo sesisekelo, futhi akufanele kube nokuphambuka, ukushwabana noma i-Stack Phenomenon esindayo. Ingxenye eseduze ehambisanayo yonqenqema ohlangothini lobude benethiwekhi yokukhipha amanzi ehlanganisiwe okungenani ingu-100 mm, Sebenzisa futhi i-HDPE Plastic belt binding, ibhande lokubopha kufanele libekwe ku-Stack esindayo. Umgodi we-geonet okungenani eyodwa uphakathi kwengxenye futhi udlula ku-shaft ye-geonet okungenani eyodwa. Isikhala sokubopha esihlangene eceleni komthambeka ohlangothini singama-150 mm, Isikhala sokubopha phakathi kwamalunga kuzo zombili izinhlangothi zomsele wokunamathisela kanye nephansi lendawo yokulahla udoti naso singama-150 mm.
三. Imininingwane yokweqana
1, Indlela yokuhlanganisa ithanga
Uma inethi yokukhipha amanzi ye-geocomposite ihlanganiswa, kufanele kusetshenziswe izibambo zepulasitiki noma izinto ze-polymer ukuxhuma, futhi akufanele kusetshenziswe amabhande ensimbi noma izibambo zensimbi. Umbala wokumboza kufanele ube mhlophe noma ophuzi ukuze kube lula ukuhlola. Kwi-geotextile engenhla, isisindo esincane I-Stack 150 mm； I-geotextile engezansi idinga ukumboza ngokuphelele, futhi i-geotextile engenhla ingalungiswa ndawonye ngokuthunga noma ukushisela. Okungenani umugqa owodwa wezinaliti ezinezintambo ezimbili kufanele usetshenziswe ejoyintini, intambo yokuthunga kufanele ibe nemicu eminingi, futhi ukucindezelwa okuncane akufanele kube ngaphansi kuka-60 N， Kumelwe futhi kube nokugqwala kwamakhemikhali kanye nokumelana ne-ultraviolet okufana nama-geotextile.
2, imininingwane ehambisanayo
Ngesikhathi senqubo yokugqagqana, kufanele kuqashelwe ngokukhethekile ukuvalwa kwengxenye egqagqana ukuze kuvinjelwe umswakama noma izinhlayiya ezincane ukuthi zingangeni enkabeni ye-drainage mesh. Indlela yokubopha ngokushisa, izinga lokushisa kufanele lilawulwe ngokuqinile ukuze kugwenywe ukusha nge-geotextile. Zonke izingxenye ezigqagqana kufanele zihlolwe ngokucophelela ukuqinisekisa ukuthi akukho "isitishi esingekho", futhi uma kukhona okutholakalayo, imithungo kufanele ilungiswe ngesikhathi.
Ukugcwalisa emuva kanye nokuqinisa
1, Izinto zokugcwalisa emuva
Ngemva kokufakwa kwenethiwekhi yokukhipha amanzi, ukwelashwa kokugcwalisa amanzi ngemuva kufanele kwenziwe ngesikhathi. Izinto zokugcwalisa amanzi ngemuva kufanele zenziwe ngotshani noma isihlabathi esilinganiswe kahle, futhi kugwenywe ukusebenzisa amatshe amakhulu ukuze kugwenywe ukulimaza inetha lokukhipha amanzi. Ukugcwalisa amanzi ngemuva kufanele kwenziwe kuzo zombili izinhlangothi ngesikhathi esisodwa ukuze kugwenywe ukuguquka kwenethiwekhi yokukhipha amanzi okubangelwa ukulayisha ohlangothini olulodwa.
2, Izidingo zokuminyana
Izinto zokugcwalisa ngemuva kufanele zihlanganiswe ngezendlalelo, futhi ubukhulu besendlalelo ngasinye akufanele budlule ama-30 cm. Ngesikhathi sokucindezela, izindlela ezilula zomshini noma zesandla kufanele zisetshenziswe ukugwema ukucindezela ngokweqile kunethiwekhi yokukhipha amanzi. Isendlalelo sokugcwalisa emuva esihlanganisiwe kufanele sihlangabezane nobukhulu kanye nokuthamba okudingekayo kumklamo.
Ukwamukelwa nokugcinwa
1. Izindlela zokwamukelwa
Ngemva kokuqedwa kokwakhiwa, ikhwalithi yokubekwa kwenethiwekhi yokukhipha amanzi ye-geocomposite kufanele yamukelwe ngokuphelele. Okuqukethwe okwamukelwayo kufaka phakathi kodwa akukhawulelwe kulokhu: isiqondiso sokubekwa kwenethiwekhi yokukhipha amanzi, ikhwalithi yokuhlangana, ukuqina kanye nokuba yisicaba kwengqimba yokugcwalisa emuva, njll. Hlola futhi ukuthi uhlelo lokukhipha amanzi aluphazamisekile futhi uqinisekise ukuthi umphumela wokukhipha amanzi ufeza umgomo ofiselekayo.
2. Ukugcinwa Nokuhlolwa
Ngesikhathi sokusetshenziswa, inethiwekhi yokukhipha amanzi ye-geocomposite kufanele ihlolwe futhi igcinwe njalo. Okuqukethwe kokuhlolwa kufaka phakathi ubuqotho belethi yokukhipha amanzi, ukuqina kwezingxenye ezihambisanayo kanye nomphumela wokukhipha amanzi. Uma kutholakala izinkinga, kufanele zixazululwe ngesikhathi ukuze kugwenywe ukuthinta ukuzinza nokuqina kwesakhiwo sobunjiniyela.
Njengoba kungabonakala ngenhla, inethi yokudonsa amanzi ye-Geocomposite ebekwe kahle kuphela engaqinisekisa ukusebenza kwayo okugcwele. Kusukela ekulungiseleleni ukwakha kuya ekubekeni, ukuhlangana, ukugcwalisa emuva kanye nokwamukelwa, zonke izici kumele zilandele ngokuqinile izidingo zemininingwane ukuqinisekisa ukuthi yonke inqubo ihlangabezana nezidingo zomklamo. Kungale ndlela kuphela lapho ukusebenza kokudonsa amanzi kwenethiwekhi yokudonsa amanzi ye-geocomposite kungasebenza ngokugcwele futhi ukuzinza nokuqina kwesakhiwo sobunjiniyela kungathuthukiswa.
