In architecture and civil engineering, a road drain section refers to the part of a road design dedicated to managing surface water runoff to prevent water accumulation and structural damage.
It includes various elements such as side drains, gutters, culverts, and catch basins that channel rainwater away from the road surface and into proper drainage systems. Properly designed drain sections are essential for road durability, user safety, and environmental protection.
The layout, slope, and materials used in the drain section are carefully considered during the planning stage to ensure efficient water flow and reduce erosion, flooding, and maintenance issues.

In construction, a road drain section detail drawing is a technical illustration that shows the specific design and dimensions of the drainage components integrated within a roadway. This drawing is crucial for guiding construction teams in properly implementing drainage systems that ensure efficient water removal from the road surface.
These detail drawings typically include:
- Cross-sectional views of the road, showing layers such as the pavement, sub-base, and drainage structures.
- Side drains or open channels along the shoulders for surface runoff.
- Kerb and gutter systems, which collect and direct water into storm drains.
- Culverts and pipes for subsurface water flow under the roadway.
- Slopes and gradients, indicated to ensure gravity flow of water.
- Materials and dimensions, including pipe diameters, concrete specifications, and reinforcement details.
These drawings are essential in ensuring that the drainage system is correctly built to handle expected water loads, protect the road structure, and maintain safety and durability over time.
