Caij nplooj ntoos hlav hom underground ntws hose mos permeable yeeb nkab
Lus piav qhia luv luv:
Mos permeable yeeb nkab yog cov kav dej siv rau cov dej ntws thiab cov dej nag sau, tseem hu ua hose drainage system lossis hose collection system. Nws yog ua los ntawm cov ntaub ntawv mos, feem ntau yog polymers lossis hluavtaws fiber ntau, nrog dej permeability siab. Lub luag haujlwm tseem ceeb ntawm cov kav dej mos permeable yog khaws thiab tso dej nag, tiv thaiv cov dej sib sau thiab khaws cia, thiab txo cov dej hauv av thiab cov dej hauv av nce. Nws yog feem ntau siv rau hauv cov kav dej nag, txoj kev tso dej, kev tsim kho vaj tse, thiab lwm yam haujlwm engineering.
Khoom Description
Cov kav dej mos permeable siv qhov "capillary" tshwm sim thiab "siphon" hauv paus ntsiab lus los ua ke cov dej nqus, permeability, thiab kua dej. Nws cov nyhuv permeability tag nrho ua rau tag nrho cov yeeb nkab lub cev ua los ntawm cov khoom permeable, nrog rau thaj tsam loj permeable. Nyob rau tib lub sijhawm, lub zog lim dej muaj peev xwm lim tawm ntau yam zoo gravel, av nplaum, nplua xuab zeb, micro organic teeb meem, thiab lwm yam.
Khoom nta
1. Permeability: Cov phab ntsa ntawm cov yeeb nkab mos permeable muaj qee qhov porosity, uas tuaj yeem txhawb kev nkag mus rau hauv dej thiab tso dej, txhim kho av permeability, txo cov av compaction thiab dej tuav.
2. Flexibility: Cov kav dej mos permeable yog ua los ntawm cov ntaub ntawv mos, uas muaj qhov ua tau zoo thiab khoov kev ua tau zoo, thiab tuaj yeem hloov kho raws li engineering xav tau ntawm cov duab sib txawv thiab cov terrains.
3. Durability: Flexible permeable kav feem ntau yog ua los ntawm cov khoom siv polymer lossis hluavtaws fiber ntau nrog cov huab cua tsis zoo, uas muaj kev ua haujlwm zoo thiab tiv thaiv kev laus thiab tuaj yeem siv tau ntev.
4. Compressive kev ua tau zoo: Cov kav dej mos permeable muaj qee qhov compressive muaj peev xwm, tuaj yeem tiv taus qee yam loads, thiab tswj cov duab thiab kev ua haujlwm ntawm cov kav dej.
5. Kev tiv thaiv ib puag ncig thiab kev txuag hluav taws xob: Cov kav dej mos permeable tuaj yeem sau thiab siv cov dej los nag, txo cov load ntawm cov kav dej hauv nroog, thiab ua tiav cov kev siv rov qab thiab kev txuag dej nag.
6. Kev tsim kho yooj yim: Cov kav dej mos permeable yog mos thiab yooj yim rau khoov, ua rau kev tsim kho yooj yim thiab muaj peev xwm hloov kho raws li engineering xav tau ntawm cov duab sib txawv thiab cov terrain complex.
7. Kev saib xyuas yooj yim: Kev saib xyuas cov kav dej mos permeable yog qhov yooj yim, feem ntau tsuas yog yuav tsum tau ntxuav thiab tshuaj xyuas, nrog rau cov nqi kho mob qis dua.
