Technical Field

[0001] The utility model relates to the field of sponge cities, and more specifically, to a modular sponge city green space irrigation structure. Background Art

[0002] A sponge city refers to a city that can absorb and store water like a sponge when it rains. The green space irrigation structure can use the water stored during rain to irrigate green plants.

[0003] The existing technology of sponge city green space irrigation structure mostly includes a water pump and a sprinkler. The water pump sucks the stored water, and the sprinkler sprays the water on the green plants. When watering, it is necessary to water thoroughly so that the plant roots can absorb sufficient water. However, the soil infiltration rate is limited. When the soil is watered thoroughly, the humidity of the soil surface is already too high, which will cause surface runoff and waste water.

[0004] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0014] In the picture: 1. Green plant pot; 2. Drainage ditch; 3. Water diversion trough; 4. Capillary plate; 5. Leakage hole; 6. Protective mesh plate. DETAILED DESCRIPTION

[0015] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] Example: Modular sponge urban green space irrigation structure, such as Figure 1 As shown, it includes a water collection tank, a sprinkler device and a green plant module. The water collection tank can store rainwater, and the sprinkler device can use the rainwater collected in the water collection tank to irrigate the green plant module. The green plant module includes a green plant pot 1 in the shape of a cube. The green plant pot 1 is buried in the soil as a whole. The green plant pot 1 is also paved with soil and planted with green plants. Gaps are set between adjacent green plant pots 1, and the gaps form drainage grooves 2. A number of sand and gravel particles are set in the drainage grooves 2. The bottom of the drainage grooves 2 is connected to the water collection tank through a drainage network. The bottoms of the side walls of the green plant pots 1 are all opened. A water diversion trough 3 is provided, and a capillary plate 4 is arranged in the water diversion trough 3. The capillary plate 4 extends to the drainage ditch 2 and the green plant pot 1. Tiny capillary pores are formed on the capillary plate 4. The water infiltration rate of sand and gravel particles is much greater than the water infiltration rate of soil. The water sprayed by the sprinkler irrigation device can quickly pass through the drainage ditch 2 and fall on the capillary plate 4. Through capillary action, the water can be conducted through the capillary plate 4 and enter the green plant pot 1 through the water diversion trough 3. The moisture can be transferred to the bottom of the green plant pot 1, quickly soaking the soil at the bottom of the green plant pot 1, and irrigating the soil faster, which can save water.

[0017] Sand and gravel particles include coarse sand particles and fine sand particles. The coarse sand particles are located above the fine sand particles. The particle size of the coarse sand particles is larger than that of the fine sand particles. There are larger gaps between the coarse sand particles, which can allow water to pass through quickly and can also filter out larger impurities. The gaps between the fine sand particles are smaller, which has a finer filtering effect. The water flows through the coarse sand particles first and then through the fine sand particles. The impurities are gradually filtered out, making the filtering effect better.

[0018] A plurality of drainage holes 5 are vertically provided on the capillary plate 4. When it rains heavily, the drainage ditch 2 itself can drain water quickly, and the drainage holes 5 can also drain excess rainwater quickly, thus preventing the capillary plate 4 from blocking drainage during heavy rain.

[0019] The capillary plate 4 is made of PP material, which is non-toxic and harmless and has excellent mechanical properties, can avoid rainwater pollution, and has good durability.

[0020] A protective mesh plate 6 is arranged under the green plant module. The protective mesh plate 6 is made of PP material, which can evenly distribute the weight of the green plant module and sand and gravel particles on the soil under the protective mesh plate 6, prevent local settlement of the soil, and have better stability.

[0021] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
