Drainage Profile Layout With Manhole Levels, Pipe Sizes, and Slopes

This AutoCAD DWG drawing presents a detailed drainage profile layout showing underground pipeline alignment between multiple manholes with accurate engineering data. The drawing includes profiles such as MH 38 to MH 52, MH 22 to MH 31, MH 9 to MH 34, MH 59 to AH2, MH 7 to MH 41, and MH 62 to AH3. Pipe diameters of 300 mm, 450 mm, and 600 mm are clearly marked along each profile, along with individual pipe lengths like 27.73 m, 32.50 m, 38.64 m, 29.77 m, and 35.69 m. Longitudinal sections display continuous gradients with slopes ranging from 0.30 percent to 1.72 percent, supporting proper flow design and hydraulic performance. Drainage manhole inner heights, rim elevations, and invert elevations are systematically tabulated to ensure precise vertical coordination across the network.

The drawing is scaled horizontally at 1 is to 750 and vertically at 1 is to 200, allowing clear visualization of level variations and depth control. Each profile includes elevation references in meters, supporting accurate setting out and site execution. The drainage profiles are organized for easy comparison between segments, enabling engineers to review flow direction, depth transitions, and pipe continuity. This drainage profile layout is suitable for civil engineers, infrastructure planners, and contractors who require clear manhole to manhole drainage detailing with verified pipe sizes, slopes, and elevation data for construction and coordination.
