Hauv kev tsim kho vaj tse, qhov teeb meem ntawm cov av nplaum yeej ib txwm tseem ceeb heev. Peb lub voj voog dej ntws sib xyaw ua ke Nws yog cov khoom siv dej ntws uas siv ntau hauv cov haujlwm loj. Yog li, nws puas tuaj yeem tiv thaiv cov av nplaum thiab thaiv?
1. Kev tsim kho tshiab ntawm cov qauv
Peb-seem Composite drainage network Muaj ob sab geotextile thiab peb-seem geotextile core. Lub mesh core yog ua los ntawm high density polyethylene (HDPE) Cov txheej txheem molding peb-seem tsim cov kab sib txuas criss-crossing, thiab nws qhov tshwj xeeb yog pom tseeb hauv ob qho hauv qab no:
1 、 Qhov system gradient pore: qhov ntsug tav spacing ntawm lub mesh core yog 10-20 hli ， Lub tav inclined sab saum toj thiab lub tav hauv qab tsim ib txoj kab peb-seem, uas yog phim nrog lub aperture gradient tsim ntawm geotextile (txheej sab saud 200 μm ， Qib qis dua 150 μm ） ， Interceptable particle loj dua 0.3 hli Ntawm particulate teeb meem, Tam sim no tiag tiag "coarse filtration-fine filtration" graded filtration.
2, Tsim kom tsis txhob muab embedding: mesh core rib thickness txog li 4-8 hli, Hauv 2000 kPa Ntau tshaj 90% ntawm cov tuab qub tseem tuaj yeem tswj tau hauv qab load, yog li kom tsis txhob muaj geotextile raug embedded hauv mesh vim yog qhov chaw compression. Raws li cov ntaub ntawv engineering ntawm qhov chaw pov tseg, tom qab 5 xyoos ntawm kev siv, cov txheej dej ntws siv cov khoom siv no yuav ua dej Tus nqi attenuation tsuas yog 8%, uas qis dua 35% ntawm cov txheej gravel ib txwm muaj.
2. Cov khoom siv
1, Kev Ruaj Ntseg Tshuaj: HDPE Lub hauv paus mesh yog resistant rau acid thiab alkali corrosion. Hauv pH Hauv ib qho tsis muaj zog acid thiab tsis muaj zog puag ncig nrog tus nqi ntawm 4-10, nws cov qauv molecular ruaj khov khaws cia tus nqi tshaj 95%. Ua ke polyester Filament geotextile Lub UV-resistant txheej tuaj yeem tiv taus cov khoom laus los ntawm UV hluav taws xob.
2, Lub tshuab ntxuav tus kheej: qhov roughness ntawm qhov mesh core Ra Value tswj tau ntawm 3.2-6.3 μm Hauv qhov ntau, nws tsis tsuas yog ua kom cov dej ntws zoo xwb, tab sis kuj zam kev nplaum biofilm los ntawm kev du ntau dhau.
3. Kev xyaum ua haujlwm engineering
1. Daim ntawv thov rau qhov chaw pov tseg: Hauv qhov chaw pov tseg uas muaj peev xwm ua tiav txhua hnub ntawm 2,000 tons, lub network dej sib xyaw ua ke peb-seem thiab HDPE Lub membrane tsim cov txheej txheem tiv thaiv kev nqus dej. Nws lub plawv mesh peb-seem tuaj yeem tiv taus 1500 m³ ib hnub. Lub nra hnyav ntawm leachate, ua ke nrog lub luag haujlwm backstop ntawm geotextile, tuaj yeem ua tiav percolation. Cov kua dej raug tso tawm hauv ib qho kev taw qhia, uas tuaj yeem tiv thaiv sludge los ntawm kev rov qab ntws. Tom qab 3 xyoos ntawm kev ua haujlwm, qhov siab poob ntawm cov dej ntws laminate tsuas yog 0.05 MPa, qis dua qhov tsim qauv ntawm 0.2 MPa.
2, Daim ntawv thov kev tsim kho txoj kev: Hauv txoj kev loj hauv thaj chaw av khov hauv sab qaum teb Suav teb, nws tuaj yeem siv ua txheej dej ntws hauv qab, uas tuaj yeem txo qib dej hauv av los ntawm 1.2% los ntawm kev thaiv qhov nce ntawm cov dej capillary m. Lub zog tawv ntawm nws lub mesh core yog 120 kN / m, Nws tuaj yeem txwv qhov kev hloov pauv ntawm cov txheej hauv paus sib sau ua ke thiab txo qhov tshwm sim ntawm cov kab nrib pleb. Kev saib xyuas qhia tau hais tias qhov tshwm sim ntawm cov ntu txoj kev siv cov thev naus laus zis no raug txo los ntawm 67% piv rau cov kab mob hauv qab ib txwm muaj, thiab lub neej kev pabcuam tau ntev mus txog ntau dua 20 xyoo.
3, Daim ntawv thov kev tsim kho qhov av: Hauv qhov av tsheb ciav hlau uas hla dhau cov dej nplua nuj, lub network dej ntws sib xyaw ua ke peb-seem thiab cov ntaub thaiv grouting siv ua ke los tsim cov txheej txheem dej tsis muaj dej ntawm "kev sib xyaw ua ke ntawm kev ntws thiab thaiv". Nws lub hauv paus muaj cov hydraulic conductivity ntawm 2.5 × 10⁻³m / s, Cov phaj dej ntws ib txwm muaj Txhim kho 3 zaug, koom tes nrog geotechnical Cloth Lub luag haujlwm lim dej tuaj yeem txo qhov kev pheej hmoo ntawm kev txhaws ntawm lub kaw lus dej ntws qhov av los ntawm 90%.
4. Txoj kev tswj xyuas
1, Kev soj ntsuam hauv Is Taws Nem: Cov cuab yeej siv fiber ntau optical tau muab tso rau hauv lub network dej ntws los saib xyuas cov yam ntxwv xws li hydraulic conductivity, kev ntxhov siab thiab kev ntxhov siab hauv lub sijhawm tiag tiag.
2. Kev siv dej siab siab kho: thaj chaw uas raug thaiv hauv zos, siv 20-30 MPa dej siab siab rau kev khawb av. Cov qauv tav ntawm lub mesh core tuaj yeem dais qhov siab yam tsis muaj kev hloov pauv, thiab tus nqi rov qab ntawm hydraulic conductivity tom qab kho yog ntau dua 95%.
