Abstract: A water purification and storage system comprises a water storage container, a covering plate and an impermeable wall. The water storage container is formed by a plurality of tangentially connected polygonal water-filtering wells (1). Well walls of the water-filtering wells (1) are of a water-permeable structure, and an impermeable layer (4) is arranged at the bottom of the well, wherein at least one of the water-filtering wells (1) is a water output well (14). The covering plate (2) is arranged at the upper portion of the water storage container, and comprises an impermeable covering plate (21) arranged at the upper portion of the water output well (14) and a water-permeable covering plates (22) arranged at the upper portions of the remaining water-filtering wells. The impermeable wall (3) is arranged around the water storage container. The water purification and storage system is suitable for the collection and purification of rain water.

Abstract: A composition used for high-strength impermeable concrete. The composition contains sand, stone, cement, water reducer, water and reinforced impermeable sand. The reinforced impermeable sand includes aeolian sand and binder covering the surface of the aeolian sand. The reinforced impermeable sand can fill the gap between the sand and the stone, and well combine various components in the composition, and suppress the seepage phenomenon of the molded concrete, thereby greatly improving the strength and impermeability of the concrete.

Abstract: An anti-penetration and gas permeable potting container and preparation method thereof are disclosed. The anti-penetration and gas permeable potting container is made by bonding aggregate particles with hydrophobic binder, and pores which allow gas molecules to penetrate and liquid water molecules not to penetrate are formed between adjacent aggregate particles. Further, a potting planting container applying said potting container is disclosed, wherein it includes a cultivating layer, and a base anti-penetration layer formed of waterproof and gas permeable particles which is provided between the potting container and the bottom of the cultivating layer. Pores which allow gas molecules to penetrate and liquid water molecules not to penetrate are formed between adjacent waterproof and gas permeable particles. Said pores are thoroughly distributed on the base anti-penetration layer. The container can prevent water from flowing from its bottom, and has gas permeable property.
