Mu zomangamanga zamakono ndi zomangamanga, njira zotulutsira madzi ndi zofunika kwambiri. Maukonde otulutsira madzi okhala ndi madzi ambiri amakhala ndi ntchito yabwino kwambiri yotulutsira madzi, mphamvu zambiri komanso kulimba, ndipo amagwiritsidwa ntchito kwambiri m'misewu, njanji, ngalande, mapulojekiti osamalira madzi ndi malo otayira zinyalala. Ndiye, ndi zinthu zingati zomwe zimapangidwa nazo?
Ukonde wothira madzi wophatikizika umapangidwa ndi zigawo zitatu zazikulu: maziko a pulasitiki, geotextile yolowa m'madzi ndi guluu wolumikiza ziwirizi. Zigawo zitatuzi zimagwirira ntchito limodzi kuti zitsimikizire kuti madzi akuyenda bwino, mphamvu zambiri komanso kulimba kwa netiweki yothira madzi yophatikizika.
1, Pulasitiki mauna pachimake
（1）Malo ozungulira a pulasitiki ndiye maziko a ukonde wophatikizana wothira madzi, womwe umapangidwa ndi polyethylene yolimba kwambiri (HDPE) Zipangizo zofanana za pulasitiki zolimba zimapangidwa ndi njira yapadera yopangira zinthu. Ili ndi kapangidwe kapadera ka magawo atatu, komwe kamapangidwa ndi nthiti zoyima ndi zopingasa zolumikizana. Nthitizi sizimangokhala zolimba kwambiri ndipo zimatha kupanga njira yothandiza yothira madzi, komanso zimathandizana kuti geotextile isalowe mu njira yothira madzi, kuonetsetsa kuti ukonde wothira madzi ukuyenda bwino komanso bwino.
（2）Pali mapangidwe osiyanasiyana a pulasitiki mesh core, kuphatikizapo two-dimensional mesh core ndi three-dimensional mesh core. two-dimensional mesh core imapangidwa ndi drainage mesh core yokhala ndi nthiti ziwiri, pomwe three-dimensional mesh core imakhala ndi nthiti zitatu kapena kuposerapo, zomwe zimapanga kapangidwe kovuta kwambiri mumlengalenga, zomwe zimapangitsa kuti madzi azituluka bwino komanso kuti azigwira ntchito mwamphamvu. Makamaka netiweki ya drainage ya three-dimensional composite, kapangidwe kake kapadera kamatha kutulutsa madzi apansi panthaka mwachangu ndikutseka madzi a capillary pansi pa katundu wambiri, zomwe zimathandiza pakudzipatula komanso kulimbitsa maziko.
2、Madzi olowa geotextile
（1）Geotextile yolowa m'madzi ndi gawo lina lofunika kwambiri la ukonde wophatikizana wa madzi, womwe nthawi zambiri umalumikizidwa mbali zonse ziwiri kapena mbali imodzi ya pulasitiki kudzera mu njira yolumikizirana ndi kutentha. Geotextile yolowa m'madzi imapangidwa ndi geotextile yosalukidwa ndi singano, yomwe ili ndi mphamvu yabwino kwambiri yolowera m'madzi komanso yoletsa kusefa. Mphamvu yake yoletsa tinthu tating'onoting'ono ta nthaka ndi zodetsa kuti tisalowe mu ngalande yotulutsira madzi, imalolanso chinyezi kudutsa momasuka, kuonetsetsa kuti njira yotulutsira madzi ikhale yopanda choletsa.
（2） Kusankhidwa kwa geotextile yolowa m'madzi kumakhudza kwambiri momwe netiweki yolumikizira madzi imagwirira ntchito. Geotextile yapamwamba kwambiri yolowa m'madzi sikuti imangokhala ndi kukula kwa ma pore owoneka bwino, kulowa kwa madzi ndi kulowa kwa madzi, komanso imakhala ndi mphamvu yoboola kwambiri, mphamvu ya kung'amba kwa trapezoidal ndi mphamvu yokoka, kuti iwonetsetse kuti imatha kupirira mphamvu zosiyanasiyana zakunja ndi kuwonongeka kwa chilengedwe ikagwiritsidwa ntchito kwa nthawi yayitali.
3, Womatira wosanjikiza
（1）Gawo lomatira ndilo gawo lofunika kwambiri polumikiza pakati pa maukonde apulasitiki ndi geotextile yolowa madzi. Limapangidwa ndi zipangizo zapadera za thermoplastic. Kudzera mu njira yotentha yolumikizira, gawo lomatira limatha kuphatikiza mwamphamvu pakati pa maukonde apulasitiki ndi geotextile yolowa madzi kuti apange ukonde wophatikizana wokhala ndi kapangidwe kogwirizana. Kapangidwe kameneka sikuti kokha kamangotsimikizira kukhazikika ndi kulimba kwa ukonde wolowa madzi, komanso kumapangitsa kuti kuyika ndi kuyika kwake kukhale kosavuta komanso mwachangu.
（2）Kugwira ntchito kwa guluu kumakhudza kwambiri momwe madzi amagwirira ntchito komanso mphamvu yolimbana ndi ukalamba wa guluu. Guluu ...
Monga momwe taonera pamwambapa, ukonde wothira madzi wopangidwa ndi zinthu zitatu: pulasitiki, geotextile yolowa m'madzi, ndi guluu. Zinthuzi zimagwirira ntchito limodzi kuti zitsimikizire kuti ukonde wothira madzi wopangidwa ndi zinthu zambiri ukuyenda bwino, wamphamvu komanso wokhalitsa.
