Water storage system with surface layer capable of being used for planting

Abstract

The invention relates to a water collection purification device, in particular to a water storage system with a surface layer capable of being used for planting. The water storage system with the surface layer capable of being used for the planting comprises a water storage container, a water-collecting well and water-permeable padding, wherein the container wall is in a waterproof structure, the well wall is in a waterproof structure and the water-permeable padding fills between the water-collecting well and the water storage container. Collected water is poured into the water storage container through a water pipe, an anti-seepage breathable layer is laid on the upper layer of the water-permeable padding, the anti-seepage breathable layer is formed by anti-seepage breathable granules, pores are formed among the anti-seepage breathable granules, wherein gas molecules can pass through the pores and liquid water molecules cannot penetrate through the pores. According to the water storage system with the surface layer capable of being used for the planting, due to the fact that the anti-seepage breathable layer is arranged on the top surface layer of the water storage container, on the one hand, planting moisture can be prevented from permeating and polluting stored water quality, on the other hand, air permeability of the anti-seepage breathable layer can guarantee the quality of water of the whole water storage system. The water storage system with the surface layer capable of being used for the planting can be effectively applied to water storage of cultivated wetlands.

Description

technical field [0001] The invention relates to a rainwater collection and purification device, in particular to a water storage system whose surface layer can be used for planting. Background technique [0002] At present, the global energy and water resources are scarce, and there are many water-deficient places around the world. In many water-deficient areas, people's drinking water and irrigation water have become very troublesome problems. In order to solve the water shortage problem in these areas, many areas usually rely on pumping Wells draw groundwater for drinking and irrigation needs. However, in view of the fact that groundwater resources are still relatively scarce, and these wells often need to rely on rainwater, river water and other water storage to maintain, the water directly flows into the well without being filtered and is not suitable for drinking; although the water can be slightly clearer after a long period of sedimentation, In order to maintain the ...

However, the water storage system is laid on the upper layer of the filler with a permeable surface layer made of permeable bricks or permeable materials. When the water storage system is built under the daily driving road surface, water such as rainwater on the upper layer can directly penetrate the permeable surface layer into the filler layer. , but this water storage system is not suitable for laying under the planting ground for water storage. On the one hand, the permeable surface layer cannot achieve the effect of water storage planting, and the polluted water on the surface layer can easily seep into the ground

[0004] At the same time, it is also found in the actual construction that in view of the volume limitation of the general water storage container, it is impossible to lay a deep foundation at the bottom of the water storage container like general construction. It is formed by pouring, so that the construction is more convenient, but in view of the fact that the side wall of the entire water storage container is built close to the soil foundation, and a large amount of sand is filled on the side close to the water storage container, this will cause the water storage container to be damaged. The side of the waterproof side wall close to the water storage container is under too much force, which causes the side wall to collapse, which seriously affects the construction progress and the stability of the water storage system.
