Description

Technical Field

[0001] This invention relates to the field of geotechnical engineering technology, specifically to a smart water storage system for sandstone areas and its construction method. Background Technology

[0002] Inner Mongolia Autonomous Region, especially its western leagues and cities such as Ordos, Alxa, and Bayannur (Western Inner Mongolia), is located in the core area of ​​my country's northern ecological barrier and an important energy base, characterized by a typical temperate continental arid to semi-arid climate. The region receives less than 200 mm of precipitation annually, while evaporation exceeds 2000 mm, resulting in extreme water scarcity and uneven spatial and temporal distribution. Water consumption per unit of GDP is 28% higher than the national average. The Yellow River's flow through the region is constrained by "red line" regulations and upstream competition, and over-extraction of groundwater has caused water levels to drop by 1-2 meters annually in some areas, exacerbating the increasingly acute water shortage problem. Simultaneously, the region's ecosystem is highly vulnerable: soil erosion covers over 45% of the total land area, desertification expands by an average of 1.5% annually, and grassland degradation and desertification seriously threaten the livelihoods of farmers and herders and national ecological security. The unique geological conditions further exacerbate the challenges of water management: the widely distributed sandstone in the area has poor cementation, disintegrating upon contact with water to form a "leakage above, blockage below" structure—the loose surface layer is difficult to retain water and is easily eroded, while the deeper rock layers prevent rainwater infiltration; the high porosity of the loess leads to severe evaporation loss of stored water, and its collapsibility makes traditional slope water storage projects (such as fish-scale pits and horizontal ditches) prone to collapse and damage. Existing water storage facilities generally suffer from structural instability, large evaporation losses, and limited capacity, making it difficult to achieve efficient interception and long-term utilization of rainwater resources.

[0003] Against this backdrop, the national strategic guidance of "prioritizing water conservation and determining afforestation based on water availability" has placed rigid demands on the ecological restoration of western Inner Mongolia: areas with annual precipitation below 400 mm must focus on rain-fed water conservation and scientifically restore vegetation. As the main body of the northern agro-pastoral ecotone, implementing "determining grazing based on water availability" requires solving the problem of grassland water supply—an innovative technology that can adapt to the special geology of sandstone-loess, efficiently collect and store slope runoff, reduce soil erosion, and support precise water supply to vegetation is urgently needed. This technology should scientifically constrain livestock carrying capacity based on water resource carrying capacity to achieve synergy between ecological protection and sustainable development of animal husbandry.

[0004] Existing technical solutions reduce rainwater infiltration by leveling and compacting the slope to form a natural slope, using gravity to collect rainwater, and employing a multi-gradient structure to filter sediment. Existing technologies also lay clay or concrete impermeable layers at the bottom of the catchment area and on the surface of the slope to reduce rainwater infiltration losses, while adopting an open-air design to achieve natural rainwater storage by relying on low-lying areas of the terrain.

[0005] In existing technologies, the relevant equipment adopts an open-air structure design, which leads to significant water loss due to evaporation in the natural environment, resulting in ineffective evaporation and waste of water resources; its large size makes it difficult to adapt to the installation and use requirements under different site conditions, creating spatial layout obstacles for large-scale application; it directly utilizes rainwater and lacks water body testing, thus failing to ensure that the water quality provided meets the safety standards and health requirements for livestock drinking; and it does not consider the ecological functions of plant roots or the environmental improvement effects of vegetation systems. Summary of the Invention

[0006] In view of the shortcomings of the existing technologies, and in response to the challenges of water scarcity, geological constraints, failure of traditional engineering, and the strategic need for "water-based grazing", this invention proposes the "Kongdui Smart Water Storage System and its Construction Method in Arsenic Sandstone Area". It aims to break through the bottleneck of slope water storage and utilization through structural innovation and intelligent regulation, and provide core support for regional ecological security and sustainable animal husbandry.

[0007] The present invention adopts the following technical solution: A smart water storage system for arsenic sandstone areas includes a vertical water collection tank, a water collection pipe at the bottom of the vertical water collection tank, a sedimentation tank connected to a sedimentation tank, a filter connected to a water storage tank, and a water extractor installed on the water storage tank, which is powered by a solar panel. The connection between the water collection pipe and the sedimentation tank is equipped with a drop stone. A sand discharge port is installed on the side of the sedimentation tank. A pressure sensor is installed at the bottom of the sedimentation tank. When the pressure sensor reaches a threshold, the sand discharge port is activated. A first heavy metal sensor and a laser turbidity sensor are installed at the outlet of the sedimentation tank. A valve is installed on the pipe between the sedimentation tank and the filter. A water level detector, a second heavy metal sensor, an ultraviolet germicidal lamp, and an E. coli detector are installed on the water storage tank. The water level detector controls the opening and closing of the valve. The ultraviolet germicidal lamp receives the signal from the E. coli detector. When the pathogenic bacteria exceed the standard, enhanced sterilization is activated.

[0008] The area is planted with Suaeda salsa, which is highly resistant to adverse conditions, salt, moisture, and poor soil. Its ability to be planted in this region not only helps to stabilize the soil but also greatly improves the regional environment.

[0009] Drainage channels are placed at the bottom of this system to guide rainwater left on the slope during the rainy season, and the amount of sediment deposited in the channels can be used to determine the soil erosion situation in the area.

[0010] The filter is equipped with burlap, which is placed in the top and bottom layers of coarse gravel, medium gravel, and fine gravel arranged from top to bottom. Below the burlap under the fine gravel is fine sand, and below the fine sand is activated carbon. The different materials filled in the layers can purify the rainwater that seeps into and stores, while improving the effective utilization rate of the infiltrated rainwater.

[0011] The vertical water collection tank is made of acrylic material with holes and a simple filter screen inside; the water collection pipe is designed with a slope of 3-8% (the slope design allows the rainwater collected by the pipe to be better gathered together).

[0012] The implementation method is as follows: 1) Buried facilities: After the system facilities are buried, self-inspection should be carried out at fixed intervals throughout the year. During daily use, the water quality should be continuously monitored to ensure that it meets the standards for livestock drinking water and to provide basic protection for the safety of livestock water. 2) Inspect the water storage status of the reservoir: Regularly inspect the water storage status of the reservoir, locate the faulty reservoir through sensor data in the control room, and check the operational stability of the entire monitoring system to ensure the continuous and effective operation of the system. 3) System operation and maintenance: To ensure the filtration effect, the filter media in the filter needs to be replaced regularly, the filter screen in the vertical water collection tank needs to be cleaned, and consumables for various sensors need to be replenished regularly to ensure that the monitoring functions are normal. 4) Sediment removal: Clean the sand discharge outlet regularly to prevent silt blockage from affecting the sand discharge function, ensure the normal operation of the sedimentation tank and drainage channel, and maintain the system's silt treatment capacity. 5) Data processing: Unify the export of various types of data monitored by the system, analyze the soil and water conservation status and environmental changes in the region, and provide a basis for system optimization and regional ecological assessment.

[0013] This invention primarily protects the Kongdui intelligent water storage system and its construction method in arsenic sandstone areas. It is adapted to the special geology of arsenic sandstone-loess and breaks through the bottleneck of slope water resource storage and utilization through structural innovation and intelligent regulation. It also protects the composite water storage structure integrating intelligent monitoring modules and ecological vegetation layers, intelligently monitors water quality and coordinates regulation, and combines vegetation ecological functions to achieve water storage and ecological synergy. An ecological protection system that combines drought-resistant vegetation with engineering structures to enhance slope erosion resistance utilizes the root system of vegetation to stabilize and improve the soil, while engineering structures enhance the slope's erosion resistance and prevent soil erosion.

[0014] In response to the problem of high water evaporation loss caused by open-air structures in existing technologies, this invention aims to enhance the natural water storage capacity of the land, realize the comprehensive utilization of rainwater and shallow groundwater, reduce the ineffective evaporation and waste of water resources, and improve utilization efficiency.

[0015] This invention utilizes an integrated system to achieve real-time detection and targeted intervention of water quality, solving the problems of existing technologies lacking water detection and failing to guarantee water quality safety; This invention meets the water needs of livestock farming while achieving synergistic optimization of water conservation and land protection through ecological design.

[0016] Beneficial effects This invention can improve the problem of water evaporation caused by open-air structures in existing technologies, combining water storage and water retention to improve water resource utilization. It has enabled the comprehensive utilization of rainwater and shallow groundwater, enhanced the natural water storage capacity of the region, provided water resource support for the implementation of the "water-based grazing" strategy, helped balance the relationship between ecological protection and pastoral development, and promoted sustainable development. It can monitor water indicators in real time and coordinate with the filtration system to ensure the safety and health of livestock drinking water from a technical perspective, and meet the high standards for livestock water. It can be combined with drought-resistant vegetation planting and biological seepage prevention technology to improve soil structure by using plant roots to stabilize the soil, thereby simultaneously achieving soil and water conservation and enhancing natural water storage capacity. Attached Figure Description

[0017] To more clearly illustrate the technical solutions of this application, the accompanying drawings used in this application will be briefly described below. Obviously, the drawings described below are merely some embodiments of this application. For those skilled in the art, other drawings can be obtained from these drawings without any creative effort.

[0018] Figure 1 This is an overall diagram of the present invention; Figure 2 This is a side view of the present invention; Figure 3 This is a schematic diagram of the filter of the present invention. Detailed Implementation

[0019] The following will be combined with the appendix Figure 1-3 The embodiments of the technical solution of this application are described in detail below. The following embodiments are only used to illustrate the technical solution of this application more clearly, and are therefore only examples and should not be used to limit the scope of protection of this application.

[0020] The present invention will now be described in further detail with reference to specific embodiments.

[0021] Example 1 The functions and connections of each part are as follows: Figure 1The system consists of three parts: 1. A vertical water collection tank made of high-strength acrylic material that inhibits bacterial growth. The tank has perforations to collect shallow water through seepage. An internal simple filter screen pre-filters sediment, achieving initial collection and pre-treatment of rainwater and shallow groundwater. The collected water is then transported to a sedimentation tank via a collection pipe. 2. The collection pipe, designed with a 5% slope, gathers the water from the vertical collection tank and guides the flow to the sedimentation tank, achieving directional water transport. 3. The sedimentation tank treats the collected water through sedimentation, reducing the sediment content. 4. The filter, after treatment, deeply filters the water after sedimentation in the sedimentation tank. Through a multi-layered structure, it intercepts silt particles and colloidal substances, adsorbs microorganisms, organic pollutants, and some heavy metals, reducing the content of microorganisms and fine particles in the water and purifying the water quality; 5. The reservoir stores the water purified by the filter, serving as a water resource reserve unit to provide a stable water source for subsequent needs such as livestock drinking; 6. The water extractor pumps water from the underground reservoir for direct use; 7. The solar panel generates electricity using solar energy to provide power for the electrical equipment in the system, ensuring the energy supply for the intelligent operation of the system; 8. Suaeda salsa absorbs heavy metals in the soil and improves the environment of the sandstone soil, thus meeting water demand while playing an ecological role in conserving water sources and protecting the land, contributing to soil and water conservation and ecological restoration; 9. The drainage ditch is mainly used to monitor the amount of silt deposited in the ditch. The sedimentation data can be used to evaluate the regional soil erosion situation and provide a reference for ecological protection and system optimization.

[0022] A drop stone 10 is installed at the connection section between the water collection pipe 2 and the sedimentation tank 3. A sand discharge port 11 is installed on the side of the sedimentation tank 3. A pressure sensor 12 is installed at the bottom of the sedimentation tank 3. When the pressure sensor 12 reaches the threshold, the sand discharge port 11 is activated. A first heavy metal sensor 16 and a laser turbidity sensor 13 are installed at the outlet of the sedimentation tank 3. A valve 14 is installed on the pipe between the sedimentation tank 3 and the filter 4. A water level detector 15, a second heavy metal sensor 17, an ultraviolet germicidal lamp 18 and an E. coli detector 19 are installed on the water storage tank 5. The water level detector 15 controls the opening and closing of the valve 14. The ultraviolet germicidal lamp 18 receives the signal from the E. coli detector. When the pathogenic bacteria exceed the standard, enhanced sterilization is activated.

[0023] Figure 2In the middle section, a dropper 10 is installed at the connection between the water collection pipe and the sedimentation tank. By reducing the water flow velocity, it prevents the sediment from being stirred up by impacting the bottom sediment, thus ensuring the sedimentation effect. A sand discharge port 11 transmits signals to the pressure sensor on the right side as sediment accumulates at the bottom of the tank. A pressure sensor 12 is installed at the bottom of the sedimentation tank to monitor the weight of the accumulated sediment. When a threshold is reached, the sand discharge port is activated to automatically clean the sediment, ensuring the effective volume of the sedimentation tank. A first heavy metal sensor 16 (multi-parameter electrochemical sensor) is installed at the outlet of the sedimentation tank to initially detect the heavy metal content in the water, providing a preliminary assessment of water quality safety. A valve 14 is located on the pipe between the sedimentation tank and the filter, receiving signals from the water level detector 15. The filter is shut off when the water level reaches the standard to prevent the filter layer from shortening its service life due to prolonged immersion. The laser turbidity sensor 13, installed at the filter outlet, detects the turbidity of the water to determine whether it meets the drinking water standards for livestock and ensures that the physical indicators of the water quality meet the standards. The second heavy metal sensor 17, located after the filter, performs secondary detection of the water, ensuring water safety while indicating whether the filter material needs to be replaced. The ultraviolet germicidal lamp 18 performs routine water sterilization and receives signals from the E. coli detector. When the pathogenic bacteria exceed the standard, enhanced sterilization is activated to ensure the safety of the water microorganisms. The E. coli detector 19 activates the ultraviolet lamp for sterilization when the E. coli level reaches a certain level.

[0024] Figure 3 Medium: Linen 41: Primarily serves as support and isolation, acting as the base or layering material for the filter. It prevents larger particles such as coarse and medium gravel from mixing into the finer filter layer below. It also initially blocks larger suspended impurities in the water, preventing them from directly entering subsequent fine filtration stages and causing blockages. Coarse Gravel 42: As the first-stage filter layer, its larger particles intercept larger particles such as silt and stones in the water, reducing the burden on subsequent fine filtration layers and initially purifying the water. Medium Gravel 43: Can further purify the water... Medium-sized impurities are filtered in the water, receiving the water after the first stage of filtration; Fine gravel 44: with a smaller particle size, it can filter finer silt particles in the water, further purifying the water after the medium gravel filtration; Fine sand 45: can intercept fine suspended particles and colloidal substances in the water, further purifying the water quality; Activated carbon 46: has strong adsorption properties, can adsorb microorganisms, organic pollutants, odors and some heavy metals and other harmful substances in the water, deeply purifying the water quality and ensuring that the filtered water meets the safety standards for subsequent livestock drinking.
