Daim duab hauv qab no qhia cov yeeb nkab poob thiab qhov deb
- PUAS = GRADIENT X DISTANCE.
- Hloov qib.
- Qib ntawm lub crown ntawm lub cev = lub invert theem + internal txoj kab uas hla ntawm lub cev + cev phab ntsa thickness.
- Manholes tuaj yeem tsim los ntawm masonry lossis precast qhob.
Hais txog qhov no, lub caij nplooj zeeg yuav tsum muaj pes tsawg lub yeeb nkab?

Dab tsi yog qhov tsawg kawg nkaus poob ntawm cov kav dej kav dej? Standard Kab rov tav Drainage Pipe Slope
| PIPE DIAMETER | MINIMUM SLOPE |
|---|---|
| 2 1/2 "los yog me dua | 1/4 "rau ko taw |
| 3 "rau 6" | 1/8 "rau ko taw |
| 8" los yog loj dua | 1/16 "rau ko taw |
Tsis tas li ntawd, koj yuav suav li cas poob rau hauv cov yeeb nkab?
Faib cov cev s ntsug poob los ntawm qhov ntev ntawm cov cev , ces muab qhov tshwm sim los ntawm 100 kom pom qhov feem pua. Cov poob thiab ntev yuav tsum nyob rau hauv tib chav (ko taw lossis ntiv tes) rau qhov no ua haujlwm. Piv txwv li, yog tias cov cev poob ntawm ib ko taw thiab ntev 50 ko taw, koj faib 1 los ntawm 50 kom tau 0.02.
Lub caij nplooj zeeg ntawm 1 ntawm 40 yog dab tsi?
A 1 ua 40 cev poob txhais tau tias rau txhua tus 40 units ntawm qhov ntev, cov yeeb nkab yuav poob los ntawm 1 chav tsev. Piv txwv li, hauv a 40 'meter' khiav ntawm cov yeeb nkab, ntsug poob ntawm cov yeeb nkab khiav yuav yog 1 ' meter '
