Storage Tank Project Detail with Hermetic Sealing and Channel Base

This Storage Tank Project AutoCAD drawing presents a detailed inspection box and underground tank construction layout with precise plan and section views. The drawing includes hermetic sealing with a removable cover, a round steel handle, and a gasket arrangement for airtight performance. Wall construction is shown using half brick masonry with burnt bricks, internal mortar plaster finish, and a regulated mortar ratio of 1:3. Dimensional details such as variable width minimum 60 cm, wall thickness, pipe inlet and outlet positioning, and elevation references are clearly marked for accurate site execution. The plan view explains pipe alignment and chamber sizing, supporting proper drainage and storage coordination.

The section detail further illustrates the channel background detail with curved base canaleta, concrete blinding layer, leveling mortar, and compacted ground below. Structural elements include concrete slab thickness, base support, and internal channel slope for smooth flow. Height variations, sealing points, and construction layers are clearly defined to ensure durability and maintenance accessibility. This AutoCAD DWG file is useful for architects, civil engineers, and builders working on storage tank systems, inspection chambers, and underground utility projects. The drawing is compatible with AutoCAD, 3D Max, Revit, and Google SketchUp, making it suitable for professional drafting, detailing, and construction documentation.
