Hongyue tri-dimension composite geonet rau kev ntws dej
Kev Piav Qhia Luv:
Peb-dimensional composite geodrainage network yog ib hom khoom siv geosynthetic tshiab. Cov qauv sib xyaw ua ke yog lub plawv geomesh peb-dimensional, ob sab yog nplaum nrog cov geotextiles uas tsis yog woven. Lub plawv geonet 3D muaj ib daim tav ntsug tuab thiab ib daim tav diagonal nyob rau sab saum toj thiab hauv qab. Cov dej hauv av tuaj yeem tawm sai sai ntawm txoj kev, thiab nws muaj lub kaw lus tswj qhov hws uas tuaj yeem thaiv cov dej capillary thaum muaj kev thauj khoom ntau. Tib lub sijhawm, nws kuj tseem tuaj yeem ua lub luag haujlwm hauv kev sib cais thiab kev txhawb nqa lub hauv paus.
Cov Khoom Piav Qhia
Kev nyab xeeb thiab lub neej ua haujlwm ntawm txoj kev tsheb ciav hlau, txoj kev loj thiab lwm yam kev thauj mus los hauv paus tseem ceeb muaj feem cuam tshuam nrog lawv tus kheej lub kaw lus ntws dej, uas cov ntaub ntawv geosynthetic yog ib feem tseem ceeb ntawm lub kaw lus ntws dej. Peb-seem composite drainage network yog ib hom tshiab ntawm cov khoom siv geosynthetic, peb-seem composite drainage network yog ib hom tshiab ntawm cov khoom siv geosynthetic, peb-seem composite drainage network yog ib hom tshiab ntawm cov khoom siv geosynthetic. Peb-seem composite geodrainage network muaj peb-seem qauv ntawm cov yas mesh ob-sab bonded permeable geotextile, tuaj yeem hloov cov xuab zeb thiab xuab zeb ib txwm muaj, feem ntau yog siv rau qhov chaw pov tseg, txoj kev thiab qhov av sab hauv phab ntsa ntws dej.
Cov yam ntxwv ntawm cov khoom
Tri-dimension composite geonet rau kev ntws dej yog ua los ntawm ib qho tshwj xeeb tri-dimension geonet coated nrog geotextile ntawm ob sab. Nws muaj cov khoom ntawm geotextile (filtration) thiab geonet (dej ntws thiab kev tiv thaiv) thiab muab ib qho kev ua haujlwm ntawm "filtration-drainage-protection". Lub qauv tri-dimension tuaj yeem dais qhov hnyav dua hauv kev tsim kho thiab tseem muaj qee qhov tuab, lub zog thiab zoo heev hauv kev coj dej.
Scope ntawm Daim Ntawv Thov
Kev ntws dej ntawm cov chaw pov tseg; Kev ntws dej ntawm txoj kev loj thiab txoj kev taug kev; Kev txhawb nqa kev ntws dej ntawm txoj kev tsheb ciav hlau; Kev ntws dej ntawm txoj kev tsheb ciav hlau, kev ntws dej ntawm txoj kev tsheb ciav hlau ballast thiab ballast, kev ntws dej ntawm qhov av; Kev ntws dej ntawm cov qauv hauv av; Kev ntws dej ntawm phab ntsa rov qab; Kev ntws dej ntawm lub vaj thiab chaw ua si.
