Curved Drainage Structure CAD Drawing with RCC Sections and Dimensions

This curved drainage structure CAD drawing provides complete technical details for water management and structural construction projects. The drawing includes a detailed plan view and multiple sectional views showing RCC side walls, curved base slab, stone pitching protection, and compacted foundation layers. It illustrates accurate dimensions for width, depth, height, and curvature, along with centerline references, slope directions, and alignment markings. The layout also highlights internal chambers, drainage flow paths, inlet and outlet positions, and masonry support details. Construction layers such as PCC bedding, RCC lining, stone packing, and backfill treatment are clearly labeled, ensuring precise drafting and smooth on site implementation for civil engineering works.
