The prompt
Engineering concept sketch of an irrigation lagoon with geosynthetic lining, based on a 53.8 m × 58 m site. Plan view: – Rectangular lagoon inside the existing sheet‑pile footprint (53.8 m by 58 m), embankments located within this boundary. – Show outer toe of the embankments aligned with this rectangle, and inner water area sized for about 5000 m³ water volume, with 70–80% working fill level. – Embankment crest width about 3–4 m, slopes 1:1.5 towards the lagoon. Cross‑section view: – Earth lagoon, no sheet‑pile walls. Excavation with side slopes 1:1.5, peat removal depth 2.0 m (note: deeper excavation possible but would require additional geotechnical analysis). – From bottom up: Native soil after peat removal. Non‑woven needle‑punched geotextile, mass 350 g/m², tensile strength at least 20/20 kN/m, as an anti‑silt and separation layer. Compacted medium sand backfill (optionally sand + screenings) up to lagoon bottom level. Drainage geocomposite layer (no geomembrane), approx. 10–15 mm thick, covering the entire lagoon bottom. Woven polypropylene reinforcing fabric, tensile strength about 40–50 kN/m, laid over the drainage layer. Optional thin leveling layer of sand/screenings. LLDPE geomembrane, thickness 1.0–1.5 mm, lining the bottom and slopes, anchored at the crest in an anchor trench. Protective interlayer between geomembrane and concrete canvas: either thin EPS/XPS boards (20–30 mm) or a second drainage geocomposite layer. Concrete canvas (flexible concrete mat) laid on the bottom and slopes, panels overlapped and fixed with ~30 mm screws and sealant; screws must not penetrate the protective interlayer or the geomembrane. – Embankments: – Option A: embankment body from compacted sand + screenings, with a non‑woven geotextile separation layer at the base. – Option B: embankment body from sand + crushed stone (20–40 mm), with possible biaxial geogrid reinforcement in intermediate layers, especially effective with coarse aggregate due to interlock. – Show water level and 1 m freeboard between water surface and crest of embankments. Output: clean CAD‑style plan and cross‑section drawing with approximate dimensions, suitable as a conceptual engineering sketch (DWG or PDF).
