Sponge soil structure capable of efficiently retaining water

The utility model belongs to the technical field of sponge soil, and discloses an efficient water retention sponge soil structure which comprises a soil component. The soil component is used for planting plants, and the soil component is used for absorbing and retaining water; a pre-embedded water storage frame is mounted at the lowest position of the soil component; a water storage cavity used for storing water is formed in the pre-embedded water storage frame, and the water outlet end of the pre-embedded water storage frame is fixedly connected with a drainage pipe; the drainage pipe is used for guiding water stored in the water storage cavity to be discharged, and a limiting groove is formed in the drainage pipe; one side of the limiting groove is rotationally connected with a one-way plate. After water is adsorbed through the soil component, the water is guided through the soil component, so that the water enters the water storage cavity in the pre-embedded water storage frame, the water collected by the
