Description

Technical Field

[0001] The invention relates to the technical field of isolation dam construction, and in particular to a method for constructing multi-water area isolation dams in natural infiltration artificial wetlands. Background Art

[0002] In economically developed areas, indoor sanitary facilities are gradually improved, courtyard floors are hardened, and flush toilets are popularized. The treatment of rural sewage needs to be adapted to local conditions. Not only should attention be paid to preventing environmental pollution, but also resource utilization should be considered. If the sewage is not reused after treatment and is directly discharged, it will cause additional waste of resources, impose a huge economic burden on rural residents or local governments, and hinder the development of the rural economy.

[0003] As a key hydraulic engineering structure in rural sewage land, the isolation dam plays a vital role in controlling water flow. It can accurately separate different sewage purification areas, ensure that each water area is treated independently, and prevent untreated sewage from mixing into the purified water area, greatly improving the treatment effect of rural sewage land. At the same time, by effectively preventing water mixing, the isolation dam provides a stable environment for sewage treatment at different stages and ensures the orderly progress of water purification;

[0004] Under existing technical conditions, isolation dams have obvious design flaws. On the one hand, it is impossible to accurately control the height. The uncertainty of height may result in the failure to play the best separation and blocking role under different water flow conditions. For example, during floods, if the height is insufficient, untreated sewage may overflow the isolation dam and mix into the purified area, destroying the stability of the entire sewage treatment system. On the other hand, it is also difficult to accurately control the width of the isolation dam. Unreasonable width may affect the passability of water flow and purification effect. An isolation dam that is too wide may hinder the normal flow of water and reduce the efficiency of sewage treatment; while an isolation dam that is too narrow may not provide sufficient stability and separation effect.

[0005] In view of this, it is necessary to carry out targeted improvement and optimization of the isolation dam to meet the specific needs of rural sewage land and ensure its maximum efficiency in the sewage treatment process. To this end, we propose a natural infiltration artificial wetland multi-water area isolation dam construction method to solve the above problems. Summary of the invention

[0035] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0036] See also Figure 1-Figure 6 , the present invention provides a method for constructing a multi-water isolation dam in a natural infiltration artificial wetland, including design and planning, isolation dam design, construction steps, vegetation configuration, monitoring and maintenance, and effect evaluation;

[0037] In the design and planning, it is necessary to conduct on-site inspections of the construction site, observe the existing ecology, vegetation, and animals, collect data on the climate, topography, and land use of the region, conduct soil analysis and soil sampling, take samples at different locations and depths, analyze soil type, texture, water content, and chemical composition, conduct soil property tests, conduct permeability, pH value, and nutrient content tests to evaluate the ability of the soil to grow plants in rural sewage lands, conduct hydrological surveys and water source analysis, determine the type of water sources such as surface water and groundwater and their flow changes, and evaluate water quality indicators such as turbidity and pollutant concentrations, water level monitoring, set up water level monitoring equipment, and record seasonal water level changes to provide a basis for design, and determine the location and scale of rural sewage lands. Spatial planning, based on the survey results, reasonably layout the location of rural sewage lands to avoid conflicts with urban infrastructure, scale calculation, based on water quality treatment needs and water volume, calculate The area and depth of the required rural sewage land, the type of rural sewage land selection type assessment, according to the water quality treatment objectives, the selected rural sewage land type such as free water surface rural sewage land, subsurface rural sewage land and mixed rural sewage land, ecological characteristics considerations, consider the impact of the selected rural sewage land type on the ecosystem, including biodiversity and habitat protection, through detailed investigation and analysis, rational allocation of land resources, reduce waste, improve water quality treatment effect, select the right type and scale of rural sewage land, help improve water purification efficiency, meet environmental standards, support ecological balance, scientific planning can effectively maintain and improve the surrounding ecological environment, promote biodiversity, reduce maintenance costs, reasonable design can reduce the later maintenance needs and costs, improve the sustainability of the project, enhance flood control capabilities, through proper design, rural sewage land can play a role in regulating water flow and alleviating flood pressure.

[0038] In the isolation dam design, the highest water level (H max ) and the minimum water level (H min ), and the annual change of water level (ΔH). Safety overheight (h s), which is generally based on experience and can be between 0.5 and 2 meters, depending on the importance of the water area and wind and wave factors. If the flow rate (Q) and the area of ​​the water area (A) are known, the flow velocity (V = Q / A) can be calculated, and the water level height (h) that may be caused by the dynamic effect of the water flow can be estimated. v ), at this time the dam height is:

[0039] H=H max +ΔH+h s +h v

[0040] Using the slope stability analysis method in soil mechanics, assuming that a safety factor is generally between 1.2 and 1.5, the preliminary formula can be expressed as:

[0041]

[0042] Where tanβ is the slope coefficient calculated based on the material and stability requirements, L is the foundation width and an additional width value determined according to the construction requirements, the impact force of the water flow is calculated based on the flow rate and velocity of the water flow, and the amount (ΔB) that needs to be increased in the dam width to resist the impact force of the water flow is determined based on the strength and impact resistance of the material.

[0043] Final dam width:

[0044]

[0045] The dam height is determined by taking into full consideration the highest water level, lowest water level, water level change amplitude, safety superelevation, and water level Yonghe value factors caused by the dynamic effect of water flow. This makes the design of the dam height more scientific and reasonable, and can effectively cope with water level changes under different hydrological conditions, and improve the safety and stability of the dam. In terms of the dam width design, not only the slope coefficient and foundation width factors based on material stability requirements are considered, but also the impact of water flow impact force is included to ensure that the dam can withstand the impact of water flow and avoid damage to the dam due to water flow impact. Taking into account a variety of factors, it can be applied to different types of waters, including rivers, lakes, and reservoirs. Whether it is a water area with large flow and drastic water level changes, or an area with complex geological conditions, targeted design can be carried out by adjusting the parameters in the formula to meet the special needs of different waters.

[0046] The parameters can be adjusted according to the actual situation. In the actual design process, the parameters in the formula can be adjusted and optimized according to the specific engineering requirements, geological survey data, and hydrological data. For example, the values ​​of internal friction angle and cohesion are adjusted according to different soil properties, and the safe overheight and water level Yonghe values ​​are determined according to the actual water flow. This flexibility enables the design to better adapt to the changes in the actual project, improve the feasibility and practicality of the design, and through scientific and reasonable formula design, the height and width of the dam body can be accurately determined to ensure that the dam body can operate stably under various hydrological conditions. This helps prevent the dam body from being submerged by floods due to insufficient height, and from collapsing due to insufficient width under the impact of water flow, providing strong protection for the safety of life and property of people in the surrounding areas.

[0047] In the construction steps, it is necessary to first clear the weeds in the construction area, use mechanical tools to clear the weeds and shrubs in the construction area, remove obstacles, remove stones and old facilities in the area, and prepare for subsequent construction. The foundation and surface are leveled. The ground is leveled by excavators and bulldozers to ensure that the foundation surface is smooth and there is no obvious height difference. Soil testing, check the bearing capacity and water content of the soil to ensure that it meets the construction requirements. Dig the dam foundation according to the design drawings, and carry out foundation excavation according to the depth and width determined by the design drawings. Monitor the depth and use measuring tools regularly to ensure that the excavation depth and width meet the design standards. Layered filling of isolation dams, layered filling, place the fill in layers, the thickness of each layer should be controlled between 15-30 cm, and it should be adjusted according to the material properties and design requirements. Density control, compact each layer after filling to ensure that the design density is reached, compaction and vibration compaction compaction method, use a tamping machine to compact each layer to ensure that the soil is dense Solid without gaps, vibration compaction, when necessary, use vibration compaction equipment to improve the density and stability of the dam body, design the overflow position to determine, determine the best location of the overflow according to the water flow calculation, construct and construct, excavate and build the overflow on the dam body to ensure its functionality and safety, completion acceptance structure inspection, comprehensive inspection of the dam body and overflow to ensure compliance with design standards, water level test, simulated water flow test to ensure that the overflow function is normal, through reasonable filling and compaction technology, significantly improve the stability of the dam body, prevent landslides, effectively prevent floods, the designed overflow can effectively drain water, reduce the pressure of floods on the dam body, protect the downstream area, save materials, layered filling and compaction methods, make material utilization more efficient, reduce engineering costs, high construction efficiency, systematic construction steps and effective equipment use, improve construction efficiency, shorten construction period, environmentally friendly, after removing weeds and obstacles can reduce damage to the surrounding ecology and promote ecological recovery.

Functional demand analysis should be carried out to determine the vegetation configuration goals based on the ecological functional needs of rural sewage lands, such as water purification and self-repair. Plants that are resistant to water and humidity should be selected. Local plants that are suitable for the rural sewage land environment, such as reeds, yellow irises, and orientals, should be selected. Diversity should be considered to ensure that plant species are diverse to improve biodiversity and ecological stability. Vegetation zoning should be designed and laid out. According to the functional needs of rural sewage lands, vegetation should be divided into different areas, such as waterside buffer zones, core rural sewage lands, and transition zones. The layers should be rich, and vertical layers should be designed based on plant height and growth characteristics to enhance ecological benefits. The best planting season should be selected for vegetation planting, usually in spring and autumn. Planting technology and the planting methods used should be confirmed. Maintain good contact between plant roots and soil to promote growth, conduct regular monitoring of post-maintenance, regularly monitor plant growth, promptly identify and deal with problems, irrigate and fertilize, provide water and nutrients as needed, promote healthy growth of vegetation, and enhance the self-repair ability of rural sewage lands. The setting of water-resistant plants can enhance the natural restoration ability of rural sewage lands, promote ecological balance, improve water purification function, and specific plants can effectively absorb pollutants in water, improve water quality, enhance the purification function of rural sewage lands, increase biodiversity, and diverse vegetation configurations provide habitats for various organisms, promote the stability and health of the ecosystem, beautify the ecological landscape, and enrich plant configurations to enhance the visual beauty of rural sewage lands, increase the potential for ecotourism and education, and prevent erosion. Plant roots can fix the soil, reduce soil erosion and erosion, and protect rural sewage lands and their surrounding environment.

[0049] After the construction is completed, monitoring and maintenance are required. Water quality monitoring and regular sampling.
