2. This application ecological drainage ditch adopts the prefabricated brick of cement, and prefabricated batch production lowers the cost, and building stones light in weight is compared to the cement brick material, obviously reduces handling cost, adopts the method of dry-laid at the bottom of the ecological drainage ditch, has improved the construction speed, therefore has reduced engineering cost.

3. Aiming at the drainage ditches in the urban water and soil conservation engineering, the water-retaining and water-draining ditch has a water-draining function, is beneficial to the restoration of natural ecological landscape, has a water-seepage function, fully utilizes water resources, and has the vegetation restoration effect and the like; the utility model is a practical drainage ditch with simple structure, convenient construction and relatively low cost; the ecological drainage ditch technology is an effective combination of water and soil conservation engineering measures and forest and grass measures.
