Description

Technical Field

[0001] This invention relates to the field of municipal engineering construction technology, and in particular to a municipal water storage and reuse reverse irrigation system and its construction method. Background Technology

[0002] my country has actively promoted the construction of sponge cities, driving the implementation of numerous comprehensive renovation projects, such as road reconstruction, renovation of old residential areas, and rainwater harvesting and reuse. These measures have effectively promoted green travel and the application of carbon-neutral technologies, bringing new vitality to urban development. However, the maintenance of urban green spaces still faces some challenges. For example, the area of ​​green spaces in parks and roadside tree pits is increasing too rapidly, requiring regular artificial spraying; large amounts of rainwater are discharged without effective utilization during heavy rains; and during road construction in dry seasons, newly planted trees have low survival rates. Under high temperatures, excessive watering of plants leads to oversaturation, which is detrimental to growth. Soil and root moisture and nutrient status are crucial for tree survival, but there are no corresponding effective measures to address these issues. Summary of the Invention

[0003] The purpose of this invention is to effectively solve the problems in existing technologies, such as the inability of sprinkler systems to meet the needs of extreme drought seasons, the large amount of manual labor required, the inability of rainwater storage and reuse, and the inability of nutrient solutions to reach the root system directly. Therefore, this invention proposes a municipal water storage and reuse reverse irrigation system and construction method.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A municipal water storage and reuse irrigation system includes a rainwater storage well, a manhole cover, a main water pipe under a tree pit, a water pump, honeycomb stones, vertical longitudinal water pipes, connectors, a flat pipe coil, a permeable drainage ring, a bend pipe, a pressure spray device, and a water level monitor. The main water pipe under the tree pit is connected to the rainwater storage well. The water pump is installed in the rainwater storage well. One end of the water pump is connected to an inlet pipe, and the other end is connected to a delivery pipe. Several vertical longitudinal water pipes are laid on the delivery pipe. A flat pipe coil is connected to the middle of the vertical longitudinal water pipes through a connector. A permeable drainage ring is arranged around the circumference of the flat pipe coil. A bend pipe is connected to the top of the vertical longitudinal water pipes. The vertical longitudinal water pipes, connectors, flat pipe coils, and permeable drainage rings are all buried underground. The top of the bend pipe protrudes from the ground and is equipped with a pressure spray device. A water level monitor is installed in the rainwater storage well.

[0006] Preferably, the water pump is an automatically controlled, bottom-mounted water pump.

[0007] Preferably, the pressure spray device includes a pressure seal, a pressure spray nozzle, and a spray eye, wherein the pressure seal includes a pressure plate.

[0008] Preferably, the planar tube coil has multiple layers.

[0009] Preferably, the system also includes a soil moisture detection device, which is connected to a signal feedback device, and a start / stop controller is connected to the water pump. The start / stop controller can control the start and stop of the water pump based on the feedback signals from the water level detector and the soil moisture detection device.

[0010] Preferably, the signal feedback device, soil moisture detection device, and start / stop controller are wired or wirelessly connected.

[0011] Preferably, the soil moisture detection device is buried in the soil layer at a horizontal distance of 50-100cm from the flat tube disc.

[0012] A construction method for a municipal water storage and reuse reverse irrigation system includes the following steps:

[0013] S1. After the rainwater storage well is completed, install the water pump and use underground buried electrical wires for terminal switch control.

[0014] S2. Install water pipes, and install the longitudinal water pipes that supply water to the green plants in sections.

[0015] S3. Then lay a 20-25cm thick layer of fill soil, then a layer of crushed stone soil with a diameter of no more than 2-3cm, and then a 5-8cm layer of honeycomb stones with soil embedded in them to form a dense structure. Use a small tamping hammer to compact it.

[0016] S4. Install the flat pipe coil and the turbulent permeable water inlet ring, inserting the turbulent permeable water inlet ring 5-10cm into the flat pipe coil;

[0017] S5. After installation, lay a 20-25cm layer of soil, and then lay a layer of honeycomb stones.

[0018] Preferably, a bend in the water pipe is installed 30-50cm below the ground level, extending 15-20cm above the ground. A pressure seal is installed on top, allowing water to flow through the pressure plate to prevent dust from entering when not in use. Water can be poured in from above to directly irrigate the roots of the plants, and excess water can flow back into the rainwater storage well. Meanwhile, the water below can be used in pump mode to achieve centralized spraying.

[0019] Preferably, the planar tube coil has multiple layers. After the upper layer of embedded soil reaches the point of covering the honeycomb stones, the upper layer of planar tube coil is installed according to the overall soil layer design thickness.

[0020] Compared with the prior art, the present invention provides a municipal water storage and reuse reverse irrigation system and construction method, which has the following beneficial effects:

[0021] By adopting the above-mentioned construction equipment and methods, the reuse of water storage in municipal road construction can be realized and integrated with the greening system. In the face of special weather, especially the dry season, the storage of natural water volume and reverse irrigation can be used to improve the survival rate of green plants. At the same time, the two-way supply of surface and groundwater storage and the use of various filling materials provide an environment for the ecosystem and make better use of the development of diverse ecosystems.

[0022] The use of flat pipe discs and turbulent permeable water-guiding rings allows water to flow through honeycomb stones, which can slowly absorb water into the soil layer and prevent it from flowing away quickly. At the same time, due to the structure of the honeycomb stones and the influence of water flow, the soil layer is further stimulated to promote the reproduction of soil-loosening organisms at the tree roots, which is more conducive to the growth of green plants.

[0023] At the same time, the targeted injection of nutrient solution from the top can directly reach the roots of the plants, and the nutrients can slowly seep into the soil, ensuring the survival rate of newly planted plants.

[0024] Furthermore, the use of soil moisture detection devices can effectively prevent over-irrigation or drought, and timely feedback on soil moisture can facilitate automated control, thereby reducing manual labor. Attached Figure Description
