Drainage Gravel Calculation
Gravel Volume = Trench Volume - Pipe Volume
The perforated pipe displaces some of the trench volume. Subtract its cross-sectional area multiplied by the trench length to get the net gravel volume. Use washed, angular gravel (3/4 to 1-1/2 inch) for good drainage.
हल किया गया उदाहरण
50 ft French drain, 12 in wide, 18 in deep, with 4-inch pipe.
- 01Trench volume = 50 x 1 x 1.5 = 75 cu ft
- 02Pipe volume = 50 x pi x (2/12) squared = 2.18 cu ft
- 03Gravel = (75 - 2.18) / 27 = 2.7 cu yd
- 04Weight = 2.7 x 1.4 = 3.8 tons
अक्सर पूछे जाने वाले प्रश्न
What kind of gravel for French drains?
Use clean, washed gravel in 3/4 to 1-1/2 inch size. Avoid crushed limestone with fines, as the fine particles can clog the system over time.
Do I need filter fabric?
Yes, wrap the pipe in filter fabric or line the trench with it to prevent soil from migrating into the gravel and clogging the drain.
