Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dry creek construction, in particular to a sponge dry creek garden ecological water storage system. Background Art
[0002] A dry creek refers to a surface ditch with pebbles and gravel at the bottom. When it is not raining, the dry creek is like a dry riverbed, which is easy to integrate with the surrounding site landscape. When it rains heavily, the rainwater collected from the rainwater downpipes and road ditches will become a trickle when flowing through the dry creek before entering other sponge facilities, and some larger suspended matter in the rainwater runoff will be intercepted. This is very helpful for preventing soil erosion and improving the performance of other sponge facilities. However, the current dry creek has a single function and can only play a landscape role. It lacks the collection and reuse of rainwater, wastes water resources, and the utilization of water resources is extremely limited.
[0003] A Chinese patent discloses a dry creek structure with a rainwater collection and irrigation system (publication number: CN205444115U), which includes a creek bed, and the soil on both sides of the creek bed is provided with vegetation. The characteristic is that the creek bed is formed by the accumulation of permeable materials, and a rainwater collection and irrigation system is provided under the creek bed. The rainwater collection and irrigation system includes a water storage tank and a plurality of drainage pipes connected to the water storage tank and leading to the soil on both sides of the creek bed. However, this dry creek structure has a single functionality and can only play a landscape role. It lacks the collection and reuse of rainwater, wastes water resources, and the utilization of water resources is extremely limited. Therefore, a sponge dry creek garden ecological water storage system is needed. Utility Model Content

[0019] Example
[0020] See also Figure 1-3 As shown, a sponge dry creek garden ecological water storage system includes a soil layer 1, characterized in that: a trapezoidal depression area is provided inside the soil layer 1, a non-woven fabric layer 2 is provided at the bottom of the trapezoidal depression area, a gravel layer 6 is provided on the top of the non-woven fabric layer 2, a coarse sand layer 5 is provided on the top of the gravel layer 6, a landscape stone layer 4 is provided on the top of the coarse sand layer 5, a vegetation layer 3 is provided on the top of the landscape stone layer 4, a water storage layer 7 is provided on the top surface of the vegetation layer 3, a permeation pipe 8 is provided on the top of the water storage layer 7, and the other end of the permeation pipe 8 passes through the water storage layer 7, the vegetation layer 3, the landscape stone layer 4, the coarse sand layer 5 and the gravel layer 6 in sequence and is connected to a water storage component.
[0021] In this embodiment, the water storage component includes a rainwater collection well 10, one end of which is connected to the infiltration pipe 8, and the other end is connected to the drainage pipe 9. By setting the drainage pipe 9, the purified rainwater in the rainwater collection well 10 can be used for irrigation or landscaping water.
[0022] In this embodiment, the inner wall of the rainwater collection well 10 is a concrete structure, and a filter grid 11 is provided inside the rainwater collection well 10 .
[0023] In this embodiment, a filter net 12 is provided on the top of the filter grid 11. The filter net 12 is made of stainless steel. The filter net 12 is a common product on the market and can be purchased directly. By setting the filter net 12, impurities brought by rainwater can be preliminarily filtered, and large particles of impurities can be blocked on the filter net 12.
[0024] In this embodiment, the filter grid 11 is a sunken inverted trapezoidal structure. The filter grid 11 is made of PVC material, which is a common product on the market and can be purchased directly. The filter grid 11 is provided with a filter groove 13. By setting the filter grid 11 and the filter groove 13 in association with each other, most of the impurities in the rainwater can be filtered, which has a certain purification effect on the rainwater.
[0025] In this embodiment, the infiltration pipe 8 is located on both sides of the pipe wall of the gravel layer 6 pipe section and is provided with reverse osmosis holes 14. The number of the reverse osmosis holes 14 is 10 to 16 and they are arranged in an array with equal spacing. When the gravel layer 6 is overfilled with water, the water enters the rainwater collection well 10 through the infiltration pipe 8 with the reverse osmosis holes 14.
[0026] The implementation principle of this embodiment is as follows: rainwater naturally falls into the aquifer 7 or gathers in the aquifer due to the terrain, allowing visible objects such as mud, dust, and fallen leaves to settle here. After that, the rainwater enters the vegetation layer 3, and the metal ions, nutrients and other pollutants that cannot be seen in the rainwater are adsorbed and degraded by the fine root system of the plants. Then the rainwater enters the coarse sand layer 5. Because the materials in the sand layer are mostly small-grained and highly permeable, the rainwater can quickly infiltrate and leave some pollutants with larger particles in the sand layer, thus completing the preliminary filtration of the rainwater. Finally, the rainwater that has undergone preliminary filtration will be collected and stored in the gravel layer 6 with many gaps. If water is stored, it will enter the rainwater collection well 10 through the infiltration pipe 8 with reverse osmosis holes 14 on the surface. Part of the rainwater will enter the rainwater collection well 10 through the double filtration of the filter screen 12 and the filter grid 11. The purified and filtered rainwater will be used as irrigation and landscape water through the drainage pipe 9.
