Kwezobunjiniyela, inkinga yokusila ibilokhu ibaluleke kakhulu. Inethiwekhi yokukhipha amanzi ehlanganisiwe enezinhlangothi ezintathu. Iyinto yokukhipha amanzi evame ukusetshenziswa kumaphrojekthi amakhulu. Ngakho-ke, ingabe ingavimbela ukusila nokuvaleka?
1. Ukusungula izinto ezintsha kwesakhiwo
Inethiwekhi yokudonsa amanzi ehlanganisiwe enezinhlangothi ezintathu Yakhiwe nge-geotextile enezinhlangothi ezimbili kanye ne-geotextile enezinhlangothi ezintathu. I-mesh core yenziwe nge-polyethylene enobukhulu obuphezulu (i-HDPE) Inqubo yokubumba enezinhlangothi ezintathu yakha inethiwekhi ye-criss-crossing rib, futhi ukuhluka kwayo kubonakala kulezi zici ezimbili ezilandelayo:
1、Uhlelo lwe-Gradient pore: isikhala sembambo eqondile se-mesh core singu-10-20 mm， Umbambo othambekele phezulu kanye nombambo ongezansi kwakha isiteshi sokuphambukisa esinezinhlangothi ezintathu, esihambisana nomklamo we-aperture gradient we-geotextile (ungqimba olungaphezulu 200 μm, Izinga eliphansi 150 μm）， Usayizi wezinhlayiya ezingabanjwa mkhulu kuno-0.3 mm Wezinto ezincane, i-Real Now "coarse filtration-fine filtration" ehlelwe ngokuhlunga.
2、Umklamo ovimbela ukushumeka: ubukhulu bembambo ye-mesh core kufika ku-4-8 mm， Ku-2000 kPa Ngaphezu kuka-90% wobukhulu bokuqala kusengakwazi ukugcinwa ngaphansi komthwalo, ukuze kugwenywe ukuthi i-geotextile ifakwe ku-mesh ngenxa yokucindezelwa kwendawo. Ngokusho kwedatha yobunjiniyela yendawo yokulahla imfucuza, ngemuva kweminyaka emi-5 yokusetshenziswa, ungqimba lokukhipha amanzi olusebenzisa le nto luzohambisa amanzi. Izinga lokunciphisa izinga lingu-8% kuphela, okuphansi kakhulu kune-35% yongqimba lwendabuko lwamatshe.
2. Izakhiwo zezinto ezibonakalayo
1、Ukuqina Kwamakhemikhali: I-HDPE I-mesh core imelana nokugqwala kwe-asidi kanye ne-alkali. Ku-pH Endaweni ebuthakathaka ye-asidi kanye nesisekelo esibuthakathaka enenani elingu-4-10, izinga lokugcina ukuqina kwesakhiwo sayo sama-molecule lidlula u-95%. I-polyester ehlanganisiwe i-Filament geotextile I-coating emelana ne-UV ingamelana nokuguga kwezinto okubangelwa imisebe ye-UV.
2、Indlela yokuzihlanza: ubulukhuni bomphezulu we-mesh core Ra Inani elilawulwa ku-3.2-6.3 μm Ngaphakathi kobubanzi, alikwazi nje ukuqinisekisa ukusebenza kahle kokukhipha amanzi, kodwa futhi ligweme ukunamathela kwe-biofilm okubangelwa ukushelela ngokweqile.
3. Umkhuba wobunjiniyela
1、Ukusetshenziswa kokulahla imfucuza: Endaweni yokulahla imfucuza enekhono lokucubungula nsuku zonke lamathani angu-2,000, inethiwekhi yokukhipha imfucuza ehlanganisiwe enezinhlangothi ezintathu kanye ne-HDPE. I-membrane yakha uhlelo oluhlanganisiwe oluvimbela ukuvuza. I-mesh core yayo enezinhlangothi ezintathu ingamelana no-1500 ngosuku m³Umthwalo womthelela we-leachate, kuhlanganiswe nomsebenzi we-backstop we-geotextile, ungafinyelela ukugeleza. Uketshezi lukhishwa ohlangothini olulodwa, okungavimbela ukugeleza kwemfucuza emuva. Ngemuva kweminyaka emi-3 yokusebenza, inani lokwehla kwengcindezi ye-drainage laminate liyi-0.05 MPa kuphela, ngaphansi komkhawulo womklamo ongu-0.2 MPa.
2、Isicelo sobunjiniyela bomgwaqo: Emgwaqweni omkhulu endaweni yenhlabathi eqandisiwe enyakatho yeShayina, ingasetshenziswa njengengqimba yokudonsa amanzi engaphansi komhlaba, enganciphisa izinga lamanzi angaphansi komhlaba ngo-1.2% ngokuvimbela ukukhuphuka kwamanzi e-capillary m. Ukuqina kwengxenye yayo ye-mesh core kungu-120 kN/m, Kunganciphisa ukufuduka kwengqimba yesisekelo ehlanganisiwe futhi kunciphise ukuvela kwemifantu ekhanyayo. Ukuqapha kukhombisa ukuthi ukwanda kwezingxenye zomgwaqo ezisebenzisa lobu buchwepheshe kuncishiswe ngo-67% uma kuqhathaniswa nezifo zendabuko ezingaphansi komhlaba, futhi impilo yesevisi inwetshwa ibe ngaphezu kweminyaka engama-20.
3、Ukusetshenziswa kobunjiniyela bemihubhe: Emhubheni wesitimela odlula ezintanjeni ezigcwele amanzi, inethiwekhi yokudonsa amanzi ehlanganisiwe enezinhlangothi ezintathu kanye nekhethini le-grouting kusetshenziswa ndawonye ukwakha uhlelo olungangeni manzi “lokuhlanganisa amanzi nokuvinjwa”. Ingaphakathi layo linomoya wokudonsa amanzi ongu-2.5 × 10⁻³m/s, Ipuleti lokudonsa amanzi lendabuko elingcono kakhulu Thuthukisa izikhathi ezi-3, ubambisane nendwangu ye-geotechnical Umsebenzi wokuhlunga unganciphisa ingozi yokuvaleka kohlelo lokudonsa amanzi emuhubhe ngo-90%.
4. Isu lokulungisa
1, Ukuqapha i-Inthanethi Yezinto: Izinzwa ze-optical fiber zifakwe kunethiwekhi yokukhipha amanzi ukuze ziqaphe amapharamitha afana nokuqhuba kwe-hydraulic, ukucindezeleka kanye nokucindezeleka ngesikhathi sangempela.
2. Ukupholisa ijethi yamanzi enomfutho ophezulu: izindawo ezivinjiwe endaweni, sebenzisa i-20-30 MPa. Ijethi yamanzi enomfutho ophezulu ukuze idonse ngendlela eqondile. Isakhiwo sembambo se-mesh core singathwala ingcindezi ngaphandle kokuguquka, futhi izinga lokubuyisa i-hydraulic conductivity ngemva kokupholisa lingaphezu kuka-95%.
Isikhathi sokuthunyelwe: Juni-14-2025
